FIELD OF THE INVENTION
The invention relates to a lamp, a housing component for a lamp, and a method for producing a lamp.
TECHNICAL BACKGROUND
The applicant is aware of luminaires which, for example, have individual luminous dots or light sources arranged linearly in a row and act as “downlights” or as “wallwashers”. The applicant is also aware of lights in which such individual light sources are provided in a matrix.
Conventional lights of the aforementioned type are limited in their configurability. A desired lighting scene or lighting effect often requires the use of multiple lights.
SUMMARY OF THE INVENTION
Against this background, the present invention is based on the object of specifying a luminaire which can be configured and then assembled in advance for a wide variety of lighting effects or lighting scenes, which is also of compact construction and yet can in particular achieve a large number of lighting effects which, despite its compact size Construction makes it possible to dissipate heat generated in an effective manner, and which is also economical to produce.
According to the invention, this object is achieved by a lamp with the features of claim 1 and / or by a housing component for a lamp with the features of claim 21 and / or by a method for producing a lamp with the features of claim 22.
Accordingly, a luminaire is proposed which has a housing component and at least one LED carrier board. The housing component has at least one section projecting from a base of the housing component, which section has a plurality of re / 57
-2 is formed relative to the base of differently oriented surfaces. The LED carrier board carries at least one LED device as a light source for providing light to be emitted by the luminaire. In the luminaire according to the invention, the LED carrier board with a rear side thereof is arranged at least in sections on one of the several surfaces of the section protruding from the base in such a way that the LED device overlaps the one of the surfaces at least in regions. Furthermore, in the luminaire according to the invention, the housing component in the region of the base thereof has at least one region which is designed as a heat sink for dissipating heat generated by the LED device during operation.
In addition, a housing component for a lamp, in particular for such a lamp, is proposed, the housing component having at least one section which projects from a base of the housing component, in particular a dome-like section, which is connected to the base in a free-standing manner and with a plurality of surfaces which are oriented differently relative to the base is trained. In the area of the base of the housing component, the housing component has at least one area which is designed as a heat sink. The housing component is also set up for fastening at least one LED carrier board, which carries at least one LED device as a light source for providing light to be emitted by the luminaire, on the housing component in such a way that heat generated by the LED device during operation exceeds the heat generated by the base projecting section can be removed into the area formed as a heat sink.
Furthermore, a method for producing a lamp, in particular a lamp of this type, is proposed according to the invention, the method comprising the steps:
- Providing a housing component with a predefined number of functional fields, the housing component having a plurality of sections protruding from a base of the housing component, which are in particular of the same design and are each formed with a plurality of differently oriented surfaces relative to the base, one of the functional fields in each of the functional fields a plurality of portions protruding from the base is arranged;
- Equipping the housing component with an LED carrier board or several LED carrier boards and / or with an assembly or several assemblies, each comprising at least one LED carrier board and at least one optical component, such that the LED carrier board or several of the LED carrier boards each with a rear side thereof being arranged at least in sections on one of the several surfaces of an associated one of the sections projecting from the base, or that one on the LED3 / 57
Carrier board provided LED device which at least partially overlaps one of the surfaces.
The idea on which the present invention is based is to propose a luminaire whose construction follows a modular system approach. The luminaire according to the invention can already be configured in a flexible manner before it is assembled, in other words before the individual parts of the luminaire are assembled, and as a result can be individually designed and shaped. There is a high degree of modularity and flexibility. The modular, configurable structure of the lamp is made possible by the housing component of the lamp provided according to the invention, the projecting section of which is formed with the surfaces oriented differently relative to the base. In this way it becomes possible, for example, to use the LED carrier board in such a way that light can optionally be emitted in accordance with the emission characteristics of a downlight or a wall washer, for example with the aid of optical components provided for this purpose. For a given size of the lamp, only a single shape of the housing component is required. One and the same type of housing component therefore enables differently configured luminaires and thus a variety of lighting effects. Depending on the desired effect that is to be achieved with the LED device and the desired main emission direction, for example in the manner of a downlight or wall washer, the rear of the LED carrier board can be placed on one of the differently oriented surfaces of the section protruding from the base , With one and the same housing component, different arrangements of the LED carrier board can be achieved with a compact and cost-saving construction of the luminaire, combined with effective heat dissipation via the section protruding from the base and the area designed as a heat sink, and thus effective cooling of the LED device. The luminaire can be configured prior to its production and delivery, for example when ordering, for example by the customer or lighting designer. The multifunctional housing component combines a housing function and a cooling function in the same component with the area acting as a heat sink. This also contributes to a compact lamp. In particular, the light can be made comparatively small to save space and still illuminate a large area.
The at least partial overlap of the LED device with the surface of the section protruding from the base is to be understood in the present case in such a way that cases are also included in which one or more further components (n ) is / are, in particular a sub-area / 57
-4 of the LED carrier board on which the LED device is arranged. In this sense, the above-mentioned superimposition can be understood in such a way that the LED device covers the area of the section protruding from the base, at least in some areas, although one or more additional components, in particular the named area of the area, between the LED device and the area LED carrier board, can be arranged. Arrangements in which the LED device is located entirely within the limits of the area mentioned or the area is completely overlaid by the LED device should also be included in particular.
Advantageous refinements and developments result from the subclaims and from the description with reference to the figures of the drawing.
In one embodiment, the housing component is cast in one piece, in particular die-cast in one piece. Such a housing component can also be produced economically with a more complex shape.
In a preferred embodiment, the housing component is formed with a metal material. In particular, the housing component can be produced from a metal material, for example by die casting. The metal material can be aluminum or an aluminum alloy, for example. Such a housing component is well suited to act as a heat sink in some areas and is also robust.
In one embodiment, a base area of the housing component is in particular rectangular or square. This can be useful in many assembly situations. However, other shapes are also conceivable.
The section projecting from the base is preferably connected to the base in a free-standing manner. This allows good access to the previous section.
In one configuration, the section protruding from the base of the housing component is designed in the form of a dome. The outer shape of the portion protruding from the base preferably has the shape of a truncated pyramid. In this way, sufficiently large and suitably oriented surfaces, for example inclined with respect to the base, can be created.
In one configuration, the shape of the truncated pyramid is a shape of a truncated pyramid, in particular a straight pyramid with a square base / 57
-5 area, formed. Other base shapes are also conceivable, in particular base areas in the form of a regular polygon. Such shapes have advantageous symmetries.
In particular, the outer shape of the section projecting from the base can have a rotational symmetry and can be imaged, for example, by rotation about an axis by a defined angle. For example, it can be provided that the outer shape of the section projecting from the base can be imaged on itself when rotated about an axis by 90 degrees, which is the case, for example, with the abovementioned shape of a truncated pyramid of a regular pyramid with a square base area. This simplifies the arrangement of the LED carrier board in sections with its rear side optionally on different surfaces of the section protruding from the base.
In one configuration, a surface of the surfaces of the section projecting from the base forms a top surface thereof and is preferably oriented essentially parallel to a main extension plane of the base. In this embodiment, further of the surfaces of the section projecting from the base are designed as surfaces inclined to the main plane of extent of the base.
In particular, the LED carrier board is arranged at least with a section of the rear side thereof on the one of the plurality of surfaces of the section protruding from the base such that the LED device overlaps the one of the surfaces at least in regions.
For example, for an LED device which provides light which is to be emitted from the luminaire in the manner of a downlight, the rear of the LED carrier board can be arranged in sections on the cover surface of the section projecting from the base. For an LED device, on the other hand, which provides light which is to be emitted from the lamp in the manner of a wall washer, the back of the LED carrier board can be arranged in sections on one of the inclined surfaces of the section projecting from the base. The various inclined surfaces can in particular offer the possibility of choosing the direction of radiation without the need for a modified housing component.
The surfaces of the projecting section which are oriented differently relative to the base can in particular be flat surfaces. This further facilitates the arrangement of the LED carrier board on one of these surfaces.
/ 57
In one configuration, the luminaire has at least one adapter component which is provided with a recess in which the section protruding from the base can be received at least in some areas. Here, an LED carrier board is attached to the adapter component in such a way that the LED carrier board attached to the adapter component placed on the section protruding from the base is arranged with a rear side thereof at least in sections on one of the inclined surfaces of the section protruding from the base such that the LED device arranged on this LED carrier board, which at least partially overlaps one of the inclined surfaces. With this configuration, a defined, stable arrangement of the LED carrier boards can be achieved in sections with their back on one of the inclined surfaces and a reliable fastening of the LED carrier board in the housing component.
In one development, the adapter component is cast in one piece, in particular die-cast in one piece. Such an adapter component can be manufactured economically.
In particular, the adapter component is formed with a metal material. Like the housing component, the adapter component can be made of a metal material, for example by die casting. The metal material can be aluminum or an aluminum alloy, for example. Such materials have favorable thermal conductivity properties for the adapter component and contribute to a robust adapter component.
In one embodiment, inclinations of opposing surfaces of the recess of the adapter component correspond to the inclinations of two of the inclined surfaces of the section projecting from the base. Furthermore, in one development, an inclination of a receiving surface of the adapter component for receiving the LED carrier board can correspond to the inclination of one of the further inclined surfaces of the section protruding from the base. Thus, in particular, a stable attachment of the adapter component to the projecting section and good heat dissipation can be achieved by a flat contact.
In a preferred embodiment, the housing component has a plurality of the sections protruding from the base, which are of the same design. Furthermore, the luminaire has a plurality of functional fields, one of the several sections projecting from the base being arranged in each of the functional fields. In particular, the section protruding from the base can in each case essentially in the middle of the function / 57
-7 field be arranged. This enables a variety of different ways to arrange LED devices in such a way that effective heat dissipation is possible in a compact and expedient manner.
The plurality of sections projecting from the base and thus also the functional fields can be arranged along a line or in accordance with a two-dimensional pattern or grid. For example, the above sections and thus the functional fields can be arranged linearly in a row or instead in a matrix. This can further facilitate the arrangement of the LED devices and the LED carrier board (s) and expand the possible combinations. Such a lamp can also be designed to be aesthetically pleasing.
In one embodiment it can be provided that the luminaire has only a single functional field. In preferred configurations, it can be provided that the lamp has a plurality of functional fields, for example two, three, four, five or six functional fields, or a different number of these, arranged in a row next to one another and thus “linearly”. In further preferred configurations, the functional fields can be arranged according to an n x m matrix with n rows and m columns, for example a 2 x 2 matrix or a 3 x 3 matrix or a 3 x 2 matrix. Here n, m are integers.
In a preferred embodiment, the functional fields can be of square shape. Other shapes, for example rectangular functional fields, are also conceivable. In particular, square functional fields can be arranged in a regular and space-saving manner.
In one configuration, the housing component in the area of the base thereof has an area assigned to this functional field for each functional field, which is designed as a heat sink for dissipating heat, which can be generated by an LED device that can be arranged in this functional field during its operation. The heat generated by each of the LED devices can thus be dissipated effectively and reliably, which can have a favorable effect on the service life of the LED devices, for example.
In one configuration, the plurality of regions designed as heat sinks are spaced apart from one another by channels on a rear side of the base, which faces away from the sections projecting from the base. This improves the cooling effect of these areas / 57
-8weiter. For example, the channels can further improve heat dissipation by convection.
In one configuration, the luminaire has a plurality of LED devices, each of which is assigned to one of the functional fields and arranged in one of the functional fields. The luminaire thus has several light sources, which is advantageous for generating different lighting effects or for lighting different areas.
In one configuration, the luminaire has a plurality of LED carrier boards, each of the LED carrier boards carrying one or more of the LED devices. Carrier boards, each carrying an LED device, can be easily combined with one another and with other LED carrier boards. The assembly of the luminaire can be simplified by arranging several LED devices on one LED carrier board. In one embodiment, all of the LED devices can be carried by the same LED carrier board.
In a further exemplary embodiment, several LED devices, each of which is assigned to one of several of the functional fields, are arranged on an LED carrier board. In this way, for example, LED devices aligned in the same way can be easily provided and installed in the luminaire.
In a further embodiment, a plurality of LED carrier boards can be provided, each of which carries one of a plurality of LED devices, each of the LED devices being assigned to one of the functional fields. In this way, the functional fields can be well equipped with LED devices in different ways, for example with differently oriented LED devices.
In one configuration, the plurality of LED carrier boards are designed differently from one another. In particular, the LED carrier boards can carry different numbers of LED devices, as a result of which, for example, one / more LED carrier boards, each with a single LED device, can be combined with one / more LED carrier boards, each with several LED devices. The housing component makes it possible to combine different LED carrier boards in one luminaire in order to realize different functional fields and lighting effects. In particular, different board shapes can be combined in one luminaire, which, for example, makes it possible to arrange LED devices to configure the luminaire in the simplest and most economical manner possible.

In one configuration, the luminaire has one optical component or a plurality of optical components. Here, the optical component (s) is / are each arranged in particular in one of the functional fields. For example, the optical component (s) is / are arranged such that a functional field, by means of the interaction of the optical component with the LED device, has a predefined radiation characteristic, for example the radiation characteristic of a downlight or a wall washer. If several optical components are provided, each of the optical components of the luminaire, in cooperation with the LED device assigned to the optical component, produces a respectively predefined radiation characteristic of the respective functional field. The radiation characteristics of different functional fields can differ from one another to produce different lighting effects and, for example, can each be designed as the radiation characteristic of a downlight or wall washer. A combination of different radiation characteristics in one luminaire is thus possible in an economical way. With the help of the advantageous design of the housing component, each of the functional fields can be selectively equipped with the radiation characteristic of a downlight or a wall washer.
In particular, the back of the LED carrier board for a functional field with the radiation characteristic of a downlight can be arranged in sections on the cover surface of the section protruding from the base. The back of the LED carrier board for a functional field with the radiation characteristic of a wall washer, however, can be arranged in sections on one of the inclined surfaces of the section protruding from the base.
The optical component can, for example, each have a rectangular or preferably square outer contour, in particular in such a way that a plurality of the optical components can be arranged next to one another to fill substantially a rectangular or square area.
In one embodiment, the optical component (s) is / are each designed as a reflector. An embodiment of the optical component (s) as a lens (s) would also be conceivable. A combination of reflector (s) and lens (s) is also conceivable.
In one embodiment, in at least a first of the functional fields, a first LED carrier board with a rear side thereof is arranged, at least in sections, on a first surface of the section protruding from the base, which is assigned to the first functional field, such that one of the first functional field is assigned to the first / 57
-10 LED carrier board carried LED device overlaps the first surface at least in some areas. In this case, a first optical component is also arranged in the first functional field, which gives the first functional field a first radiation characteristic. Furthermore, in this embodiment, in at least a second of the functional fields, a second LED carrier board with a rear side thereof is arranged, at least in sections, on a second surface of the section protruding from the base and assigned to the second functional field in such a way that a LED device carried by the second LED carrier board overlaps the second surface at least in regions. In this case, a second optical component is arranged in the second functional field, which gives the second functional field a second radiation characteristic. The first surface and the second surface are aligned in the same way relative to the base. In this embodiment, the first and second radiation characteristics can be essentially the same or different from one another. Thus, two functional fields are provided, each of which can emit light with a predefined radiation characteristic in the same main direction by means of an optical component. In particular, in a further development the first and second radiation characteristics can each be designed as a radiation characteristic of a downlight or as a radiation characteristic of a wall washer. The first and second functional fields can thus emit, for example, each in the manner of a downlight or in each case in the manner of a wall washer.
In one embodiment, in at least a first of the functional fields, a first LED carrier board with a rear side thereof is arranged, at least in sections, on a first surface of the section protruding from the base, which is assigned to the first functional field, such that one of the first functional field is assigned to the first LED carrier board carried LED device overlaps the first surface at least in regions. In this case, a first optical component is also arranged in the first functional field, which gives the first functional field a first radiation characteristic. Furthermore, in this embodiment, in at least a second of the functional fields, a second LED carrier board with a rear side thereof is arranged, at least in sections, on a second surface of the section protruding from the base and assigned to the second functional field in such a way that a LED device carried by the second LED carrier board overlaps the second surface at least in regions. In this case, a second optical component is arranged in the second functional field, which gives the second functional field a second emission characteristic. The second surface is oriented differently to the base than the first surface. The first and second Ab / 57
-11 beam characteristics can each be designed as a radiation characteristic of a wall washer. In an alternative development, the first radiation characteristic can be designed as a radiation characteristic of a downlight and the second radiation characteristic can be designed as a radiation characteristic of a wall washer.
In one embodiment, a sensor device is arranged in at least one of the functional fields. This means that the range of functions of the luminaire can be expanded with an additional function in a space- and effort-saving manner.
In further refinements, the sensor device could be designed, for example, as a presence sensor or as a brightness sensor or as a humidity sensor or as a temperature sensor. However, sensor devices for detecting other parameters are also conceivable.
In one configuration, the luminaire has a connection unit or a connection and control unit which is equipped with a plurality of connection devices by means of which the LED carrier board or more of the LED carrier boards can be / are electrically coupled to the connection unit or the connection and control unit , In this embodiment, the housing component is trough-shaped with a base, side walls, an inner region and an open side formed by the base. The housing component has in a side wall a recess that also extends into the base for receiving the connection unit or the connection and control unit, the connection unit or the connection and control unit being flat and with its main plane of extension along the side wall in sections in the interior of the housing component and is received in the recess. Such a connection unit or connection and control unit can be accommodated in a space-saving manner and enables versatile, flexible coupling with the carrier boards.
In particular, the connection unit can be arranged essentially flush with an outside of the housing component. In this way, the connection unit is arranged in a particularly space-saving manner.
In one configuration, the luminaire has a central control arrangement which provides a plurality of channels for controlling the LED device or a plurality of the LED devices. In particular, several of the LED devices can be controlled individually and / or combined in groups by means of the control arrangement. This enables a highly flexible switching and / or control of the LED device (s). Be / 57
Thus, a uniform luminaire with several light sources that can be switched and / or controlled to produce different lighting effects can be provided.
In one configuration, each of the LED devices can be controlled separately by the central control unit via one or two control channels / channels assigned to the LED device.
In particular, the central control arrangement can provide at least one control channel or at least two control channels per LED device. With at least one control channel for each LED device, each of these can be controlled separately in their light intensity. At least two control channels per LED device also allow the color of the emitted light to change, for example in the sense of "tunable white".
In further developments of the invention, several of the LED devices can be controlled via one or two common control channels.
In one configuration, the lamp can be switched and / or controlled by means of a switching and / or control signal provided wirelessly or by wire, in particular for switching and / or controlling the LED device (s) or groups thereof. The luminaire can have an interface for receiving such a switching and / or control signal in a wireless or wired way. The lamp can preferably be switched and / or controlled wirelessly and has a corresponding interface.
In one development, the central control unit can be set up to receive a switching and / or control signal for switching and / or controlling the LED device (s) or groups of the LED devices in a wireless and / or wired way, for example by means of a ZigBee Interface or a DALI interface.
In one embodiment, a power electronic component and / or a power electronic arrangement is or are arranged together with the LED device on the LED carrier board. Alternatively or additionally, the power electronic component and / or the power electronic arrangement can be provided on a further circuit board arranged at least partially within the functional field assigned to the LED device. The further circuit board can in particular be arranged at least in sections on one of the several differently oriented surfaces of the section protruding from the base, for example on one of the inclined surfaces. Leis / 57
Electronic electronic elements can thus be provided decoupled from the central control arrangement.
In one embodiment, the LED device (s) can be dimmed analogously. Analog dimming is to be understood here to mean, in particular, a current dimming which, by regulating a constant current with which the LED device (s) is / are supplied for its operation, a dimming of the light output by the LED device and thus in particular a dimming of the light emitted by the aforementioned functional field enabled. Such a dimming differs from pulse dimming, in which the dimming is achieved by switching the light source on and off periodically (“pulse”).
The LED device (s) in particular each have at least one LED. The LED device (s) can each be designed in particular as an LED (light-emitting diode or light-emitting diode) or as a group of several LEDs.
In one embodiment, the luminaire is set up to supply the LED device or LED devices of the luminaire with electrical energy by means of an external converter. This enables the provision of a luminaire which is simplified with regard to the control and supply of the LED device (s) and at the same time saves costs. In this embodiment, there is no need for power electronic components on the LED carrier board (s) or on the further board (s).
In one embodiment, the luminaire has an installation frame with which the housing component can be locked by means of spring-loaded elements, in particular spring-loaded balls, arranged on the housing component. For this purpose, the housing component can be inserted into the mounting frame, the mounting frame having an inner region corresponding to the housing component for receiving the housing component. By means of the spring-loaded balls, which in particular releasably snap into the mounting frame, the housing component can be fastened and held reliably and easily in the mounting frame. The housing component can be easily removed from the mounting frame if required.
In a further embodiment, the mounting frame is designed such that the housing component can be inserted into the interior of the mounting frame from two sides and can be latched to the mounting frame. In this way, the frame can be used in two installation positions. For example, the installation frame can be set up in a first / 57
-14Location to be installed in such a way that a first edge of the installation frame remains visible from one visible side after installation, and to be installed in a second position in such a way that a second edge of the installation frame is no longer visible from the visible side , for example by filling. This means that different installation situations can be met in a flexible manner.
In one embodiment of the method, the housing component is provided and equipped as a function of the configuration data specified by the customer when the lamp is ordered before it is manufactured. For the customer, there is the advantage of being able to select a precisely fitting luminaire configuration from a variety of possible configurations, which provides the desired effects. In the manufacture of the luminaire, a uniform housing component for each luminaire size, i.e. for each number and geometric arrangement of functional fields, can be used cost-effectively. The housing component can be used for luminaires of various configurations in the same way, without the need for post-processing.
In a further embodiment of the method, depending on the configuration data specified when the lamp is ordered, a program that can be executed by means of a data processing device of the control system is loaded onto a storage medium of a control system of the lamp. The luminaire is therefore also adapted to the selected configuration of the functional fields on the control side when it is delivered.
In one embodiment of the method, the equipping can include equipping the housing component with at least one LED carrier board and one optical component assigned to it in succession.
It goes without saying that the above refinements and developments of the invention can be applied analogously both to the luminaire according to the invention and to the housing component according to the invention and to the method of the invention.
The above refinements and developments can, if appropriate, be combined with one another as desired. Further possible refinements, developments and implementations of the invention also include combinations of features of the invention described above or below with reference to the exemplary embodiments, which are not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

DESCRIPTION OF EMBODIMENTS
A luminaire 1 according to an exemplary embodiment is illustrated in FIGS. 1 to 15. The luminaire 1 can be installed, for example, in a suspended ceiling, for example, or can be fastened to a ceiling, and attachment to other parts of a building, for example in the wall area, is also possible. The luminaire 1 is freely configurable by the customer, for example by a light designer, prior to its manufacture and delivery, for example in order to combine a plurality of light effects to be represented in the luminaire 1 in the desired manner.
The housing component 2 of FIG. 1 is die-cast in one piece from a metal material, for example aluminum or an aluminum alloy, the housing component 2 in the exemplary embodiment shown in FIG. 1 having a substantially square base area. A height of the housing component 2 is significantly less than this edge length in comparison with the edge length of the square base area thereof, as a result of which the housing component 2 has the basic shape of a flat cuboid with regard to its outer shape.
The housing component 2 has a base 3, the main extension plane 10 of which is indicated schematically in FIG. 1. In the main extension plane 10, the housing component 2 has the aforementioned essentially square base area. The main extension plane 10 is essentially parallel to a plane spanned by the directions X and Y in FIG. 1.
The housing component 2 is trough-shaped, the base 3 forming a bottom 19 of the housing component 2 and the housing component 2 further comprising side walls 20a to 20d which are connected to one another around the housing component 2 and delimit an inner region 21 of the same in the circumferential direction of the housing component 2 , In FIG. 1 above, the housing component 2 has an open side 22.
A multiplicity of projection-like sections 40 and 4 protrude upward from the base 3 in the inner region 21 in FIG. 1. Sections / 57 protruding from base 3
-184 are larger than the other sections 40. The function of sections 4 is explained in more detail below. The projection-like sections 40, which protrude into the inner region 21, are designed in different ways, but a multiplicity of the sections 40 end in a direction Z normal to the main extension plane 10 at the same height relative to the base 3 and each with a fastening opening 41 are equipped, the function of which will also be explained. In FIG. 1, for the sake of a better overview, only some of the sections 40 and the fastening openings 41 are provided with reference numerals. All sections 40, 4 are formed in one piece with the housing component 2. Many of the sections 40, and all of the above sections 4, are integrally connected to the base 3 in a free-standing manner, see FIG. 1.
Each of the sections 4 or “domes” protruding from the base 3, see FIGS. 1, 7, 9 and 10, is dome-shaped, the outer shape of the section 4 in the example shown being each the shape of a truncated pyramid of a straight pyramid with a square base equivalent. In this way, the section 4 each has a rotational or rotational symmetry about a central axis of the section 4 parallel to the direction Z, as a result of which the section 4 can be imaged on itself by rotating by 90 degrees around the central axis.
Each of the sections 4 protruding from the base 3 is of the same design as the other sections 4 and has, on an outer side thereof, a plurality of planar surfaces 5a to 5e which are oriented differently relative to the base 3. In this case, the surface 5a forms a cover surface of the section 4 which is substantially parallel to the main extension plane 10 and thus to the main extension plane 10, while the other surfaces 5b, 5c, 5d and 5e are inclined to the main extension plane 10 are and together form a lateral surface of the truncated pyramid shape, see also Figures 9 and 10. The section 4 is thus flattened on its top facing away from the base 3.
Each of the sections 4 protruding from the base 3 is assigned to a functional field 13 of the lamp 1 and is arranged centrally within the functional field 13. In the exemplary embodiment in FIGS. 1 to 15, the luminaire 1 has a total of nine functional fields 13 which, for example, can be clearly seen in FIG. 5 and are schematically identified by dotted lines. In this exemplary embodiment, the functional fields 13 are arranged in a matrix-like manner in accordance with a 3 × 3 matrix, all functional fields 13 being of the same size and each square.
/ 57
Thus, in each of the functional fields 13, a surface 5a parallel to the main extension plane 10 and a plurality of surfaces 5b-5e inclined to the main extension plane 10 with the same inclination are provided.
The base 3 of the housing component 2 has, for each functional field 13, an area 9 assigned to it, which is designed as a heat sink. See, for example, FIGS. 1, 3, 4, 6, and 8. For the purpose of better heat dissipation, each area 9 is equipped with a plurality of cooling fins 45, which are visible in particular in FIG. 8. Furthermore, the areas 9, which are formed in one piece as partial areas of the housing component 2, are arranged on a rear side 14 of the base 3, which faces away from the above sections 4, 40 and thus also from the inner area 21. The areas 9 are spaced apart from one another on the rear side 14 by channels 15 which, in the example shown, see FIG. 4, form a grid pattern. The channels 15 serve to further improve the cooling effect of the areas 9. In the channels 15 designed as air channels, an effective air flow can be achieved which, in combination with the large external surface area ratio of each heat sink area 9, contributes to effective heat dissipation. In the exemplary embodiment shown, in which there may be a high need for effective heat dissipation due to the plurality of LED devices 7, optimized heat management is thus advantageously possible.
The housing component 2 can be inserted into an installation frame 100 shown separately in FIG. 2. FIGS. 4, 5, 7, 9 and 10 each show the housing component 2 in a state inserted into the installation frame 100.
The mounting frame 100 is formed with an essentially square base area and has an inner region 101, the shape of which corresponds to the outer shape of the housing component 2 and which is provided for receiving the housing component 2. The housing component 2 can be inserted into the inner region 101 from a first open side 107 and alternatively from a second open side 108 of the mounting frame 100. Inner side surfaces of the mounting frame 100 facing the inner region 101 are provided with edges 109 and 110 facing away from one another, the edges 109, 110 being provided on all four inner side surfaces of the mounting frame 100. Spring-loaded balls 35 are arranged on the outside of the housing component 2 in the region of the side walls 20b and 20d. The edges 109, 110 form circumferential steps which can be engaged by the spring-loaded balls 35 in order to hold the housing component 2 on the mounting frame 100. Thus, the housing component 2 can be so / 57 by means of the balls 35
Lock into frame 100 when inserting from first side 107 and when inserting from second side 108.
The installation frame 100 can thus be used, for example, when installed in a ceiling in two layers, either with a visible edge 105 facing a visible side or with an invisible built-in edge 106 towards the visible side. In the area of the edge 106, the mounting frame 100 is provided on its circumferential outer side with structures 104 which, for example, facilitate “borderless” installation, for example by means of filling.
In this exemplary embodiment, the mounting frame 100 can be fastened in a ceiling (not shown in more detail in the figures) with the aid of fastening devices 102 or 103, which are arranged on the outside of the mounting frame 100, see, for example, FIG. 2. The spring-like fastening devices 102 can for mounting the installation frame 100 in such a way that the edge 105 remains visible. On the other hand, the fastening devices 103 designed as plate-like holding elements are provided for mounting the mounting frame 100 in the reverse position and thus with the edge 106 (not visible) towards the visible side. The fastening devices 103 can be inserted into the mounting frame 100 on the outside at different heights relative to the edge 106, in order to be able to take into account different thicknesses of a suspended ceiling.
It should be pointed out at this point that the section A-A shown in FIG. 9 shows the orientation of the installation frame 100, unlike the section B-B in FIG. 10, in an installation position in which the edge 106 points towards the visible side of the installed luminaire 1. In this way, the possibility of installation in the two positions of the installation frame 100 explained is to be illustrated.
The lamp 1 makes it possible to switch between different lighting effects or lighting scenes in a versatile manner by switching or controlling accordingly. The luminaire 1 provides a flexible and compact lighting solution with which the most varied lighting effects can be achieved. For this purpose, a plurality of optical components 16, each of which in the exemplary embodiment shown are reflectors, are combined with one another within the housing component 2 in the luminaire 1. In particular, the optical components 16 combined with one another in the housing component 2 are designed differently and generate different emission characteristics.
/ 57
It is thus possible with the luminaire 1 to arrange different optical components 16 in different positions within a uniform housing component 2 in a wide variety of ways. In the exemplary embodiment shown, an optical component 16 with an outer square shape in plan view is arranged in each functional field 13. 1 and 5, for better illustration of the housing component 2, only two different optical components 16 - here reflectors - are shown, but in the case of a luminaire 1 in a finished state, preferably all the functional fields 13 are filled or equipped and none of the functional fields 13 remains empty.
Light to be emitted by the luminaire 1 is provided by LED devices 7, which are designed as LEDs or groups of LEDs or have these. The LED devices 7 are illustrated by way of example in FIGS. 9, 10, 15. Each of the LED devices 7 is arranged on an LED carrier board 6 which carries the LED device 7. The luminaire 1 thus has a plurality of LED devices 7, each of which is assigned to a functional field 13 and arranged in this functional field 13. A plurality of mutually different LED carrier boards 6 are combined in the luminaire 1 according to the exemplary embodiment within the housing component 2 and fastened in the inner region 21. This will be explained in more detail below. Two different LED carrier boards 6 and associated optical components 16 are to be referred to below by way of example with the reference numerals 6a and 6b or 16a and 16b.
FIG. 1 shows an example of a first optical component 16a, which is designed as a reflector and is arranged in a first functional field 13a. The first functional field 13a forms a first luminous field, which is given a first radiation characteristic by the reflector 16a, which corresponds to the radiation characteristic of a downlight. In this example, the radiation characteristic of the first functional field 13a thus corresponds to a radiation characteristic of an individual luminaire which radiates along a main emission direction which is essentially perpendicular to the main extension plane 10, i.e. downwards when mounted on the ceiling, and for example produces a circular or elliptical, more or less bundled light cone.
Arranged in the functional field 13a is a first LED carrier board 6a, which is fastened in FIG. 1 essentially horizontally, and thus parallel to the main extension plane 10 of the base 3, in the inner region 21 of the housing component 2. The fastening of the LED carrier board 6a is on four sections 40/57 arranged around a projecting section 4 which is not visible in FIG. 1 because it is hidden by the LED carrier board 6a
-22 placed and screwed to the housing component 2 by means of screws and fastening openings 41 of these sections 40.
In FIG. 1, the optical component 16a is arranged on the LED carrier board 6a, the optical component 16a in particular being plugged onto the LED carrier board 6a and being able to be latched to the latter. In other words, the LED carrier board 6a is located in the functional field 13a between the base 3 and the optical component 16a.
Reference is now made to FIG. 9. The LED carrier board 6a carries the LED device 7 on its front side facing upwards in FIG. 9, while the LED carrier board 6 with its rear side 8, which is oriented opposite to the front side carrying the LED device 7 and points downward in FIG. 9, in the region the LED device 7 is seated on the top surface 5a of the section 4. Depending on the size and positioning of the LED device 7, the rear side 8 of the LED carrier board 6a can be arranged on the top surface 5a completely or at least partially in the area in which the LED device 7 is located on the opposite front side. The back 8 of the LED carrier board 6a thus sits in sections on the top surface 5a in such a way that the LED device 7 at least partially overlaps the top surface 5a, and to a relatively large extent in the example in FIG. 9. In the example shown in FIG. 9, the essentially complete top surface 5a lies on the rear side 8 of the LED carrier board 6a.
In operation of the LED device 7, not only light, but also heat is generated by this, which in the luminaire 1 by the contact of the rear side 8 of the LED carrier board 6a with the top surface 5a effectively and efficiently via the dome-like section 4 in the as Cooling element trained area 9 is assigned to section 4. The heat can then be dissipated further in the region 9, in particular given off to the surrounding air by convection. Effective cooling of the LED device 7 is achieved even when the light 1 and the housing component 2 are at a low height in the Z direction.
The LED carrier board 6 with the LED device 7 carried by it and the optical component 16a can form a first assembly 27a.
A second optical component 16b is arranged in the second functional field 13b, see FIG. 1, which differs from the optical component 16a. The second optical component 16b gives the second functional field 13b, which in this example forms a further luminous field, a second radiation characteristic, that of the radiation characteristic of a / 57
-23Wallwashers corresponds. In other words, when the luminaire 1 is installed on the ceiling, a main emission direction of the functional field 13b is not perpendicular to the main extension plane 10, but rather is inclined thereto, such that, for example, a wall can be illuminated.
Reference is made to FIG. 10. A second LED carrier board 6b is arranged in the second functional field 13b, which in turn carries an LED device 7 on a front side. See also FIG. 15, in which the carrier board 6b and the LED device 7 can be seen enlarged. A rear side 8 of the LED carrier board 6b, which faces away from the front side carrying the LED device 7, sits in sections on one of the inclined surfaces 5b to 5e of the section 4, in FIG. 10 as an example on the surface 5b. The rear side 8 of the LED carrier board 6b in FIG. 10 is thus arranged in sections in the region of the LED device 7 assigned to the second functional field 13b on one of the lateral surface sections of the section 4. The rear side 8 in FIG. 10 is seated in sections on one of the surfaces 5b to 5e, here 5b, in such a way that the LED device 7 overlaps the surface 5b in regions. In FIG. 10, the arrangement of the LED carrier board 6b is such that the LED device 7 carried by the LED carrier board 6b projects beyond an upper end of the section 4 and thus beyond the top surface 5a. A large part of the inclined surface 5b rests in FIG. 10 on the rear side 8 of the LED carrier board 6b.
The LED carrier board 6b in FIG. 10 is thus oriented differently than the LED carrier board 6a in FIG. 9. In FIG. 10, the LED carrier board 6b is strongly inclined to the main extension plane 10 of the base 3, corresponding to the inclination of the surface 5b with respect to the plane 10. The inclination of the surfaces 5b-5e with respect to the plane 10 can be, for example, between 75 degrees and 85 degrees, and is, for example, 81 degrees in the embodiment shown.
The optical component 16b, see for example FIG. 15, is formed with a reflecting section 16b 'which is curved and enables a lateral emission and guidance of light, inclined to the plane 10. In a lower region in FIGS. 10 and 15, the LED device 7, which is also inclined in accordance with the inclination of the LED carrier board 6b, radiates light into the reflecting section 16b '. The section 16b 'can be formed as an integral part of the optical component 16b, or the optical component 16b can be constructed in several parts, the section 16b' forming a part of the optical component 16b and can be joined together with an additional cover element.
/ 57
The LED carrier board 6b, as well as a further board 6 ', are fastened by means of screws 42 to an adapter component 11, which will now be described in more detail.
The adapter component 11, see in particular FIGS. 11 to 15, has an external shape in the manner of a lying prism, which is modified on one upper long side in FIG. 11 by a step 11 ′ and on the opposite long side in FIG. 11 by a large recess 12 is. The recess 12 has a shape which is selected such that the size and inclination of inclined flat inner surfaces 12 'and 12 correspond to the size and inclination of two opposite ones of the surfaces 5b-5e of the section 4.
The adapter component 11 has inclined first and second side surfaces 43 and 44 which face away from one another, the inclination of which in turn corresponds to that of the two opposite ones of the surfaces 5b to 5e of the above section 4 and to which the recess 12 is open. In other words, analogously to section 4, the outer shape of which corresponds to a regular truncated pyramid with a square base, all surfaces 12 ', 12, 43 and 44 of the adapter component 11 are arranged with the same inclination with respect to the main extension plane 10 of the base 3. The section 4 protruding from the base 3 can thus be accommodated in the recess 12 in four angular positions, offset from one another by 90 degrees in each case, about the central axis of the section 4, in such a way that the recess 12 is essentially completely filled and the received part of the Section 4 does not protrude over the surfaces 43 and 44.
The adapter component 11 is die-cast in one piece from a metal material, for example aluminum or an aluminum alloy, for example from the same material as the housing component 2.
In order to arrange the rear side of the LED carrier board 6b 8 on one of the surfaces 5b to 5e in the manner described above, the LED carrier board 6b is arranged on the first side surface 43 and fastened by means of the screws 42, while the further board 6 'is open the second side surface 44 of the adapter component 11 and is fastened by means of further screws 42, see FIG. 12. For fastening the circuit boards 6b, 6 ', the adapter component 11 is provided in the region of the side surfaces 43 and 44 with fastening openings 43', 44 '.
Furthermore, the optical component 16b can be plugged onto the adapter component 11 and fastened and held on the adapter component 11, for example by means of suitable fastening means, for example by latching or screwing.
/ 57
A module 27b formed with the optical component 16b, the circuit boards 6 'and 6b and the adapter component 11, see FIGS. 12 and 13, can then be placed in one of the four angular positions mentioned on one of the above sections 4 of the housing component 2. In FIG. 1, for example, the surfaces 12 'and 12 are seated on the inclined surfaces 5c and 5e.
In the bottom 19 of the housing component 2, see FIG. 5, the base 3 is provided with further fastening openings 48 arranged around the projecting section 4, one fastening opening 48 being arranged in front of each of the inclined surfaces 5b to 5e. The fastening openings 48 are thus arranged at an angular distance of 90 degrees regularly around the central axis of the section 4 parallel to the direction Z, within the respective functional field 13, and within an imaginary square defined for each functional field 13 by the associated fastening openings 41. The adapter component 11 can thus be fastened to the housing component 2 in each of the four angular positions by screwing from the rear 14 of the base 3 by means of screws 49 and the fastening openings 48 and pulled against the section 4. In this way, the adapter component 11 also comes into good contact with the section 4. The adapter component 11 is provided with suitable openings, which are not described in more detail, into which the screws 49 can be screwed through the openings 48.
The adapter component 11 therefore makes it possible to use the above section 4 without reworking the housing component 2 to equip the functional field 13b in the manner of a wall washer. In the case of the functional field 13b, the rear side 8 of the LED carrier board 6b rests in regions on the inclined surface 5b of the section 4 and in regions on the first side surface 43 of the adapter component 11. In particular, see FIG. 10, the rear side 8 lies partially in the area of the LED device 7 arranged on the opposite front side on the surface 43, while a further part of the rear side 8 rests in the area of the LED device 7 on the surface 5b, as a result of which the LED device 7 superimposed area 5b in areas. It should be mentioned that the position of the LED device 7 can vary in variants such that the rear side 8 rests essentially completely in the area of the LED device 7 on the surface 5b. Alternatively, the rear 8 in the area of the LED device 7 can be largely seated on the surface 43, in the latter case the rear 8 of the LED carrier board 6b nevertheless on the inclined surface 5b of the section 4 - or, depending on the orientation of the adapter component 11 and thus of the optical component 16b, one of the further inclined surfaces 5c, 5d or 5e - that another be / 57
-26 there is plenty of superimposition of the LED device 7 with this inclined surface, here 5b. In this way, the heat generated by the LED device 7 during operation can in turn be effectively dissipated via the section 4 into the region 9 from which it is further dissipated. The rear side of the circuit board 6 'can also rest on the surface 5d.
With a view of the area 9, FIGS. 9 and 10 also show that walls of the dome-like section 4 on the rear side 14 of the base 3 continue in cooling fins 46 connected in the manner of a square, see FIG. 8. A further cooling fin 47 radiates from corner regions of the fins 46 connected as a rectangle.
Each functional field 13 and thus each LED device 7 is therefore assigned an area 9 designed as a heat sink in order to effectively cool the LED device 7.
The functional fields 13 not yet populated in FIGS. 1, 5 are also populated to complete the luminaire 1 by fastening further LED carrier boards 6 in the housing component 2 with LED devices 7 carried by them. The heat generated by the latter during operation is again dissipated into the respectively assigned area 9 for each of the LED devices 7. The further functional fields 13 can each be set up as light fields, for example in the manner of a downlight, such as in the case of the functional field 13a, or in the manner of a wall washer, such as in the functional field 13b. With the nine functional fields 13 of FIGS. 1, 5, there are thus a multitude of possible combinations within the housing component 2.
An individual LED carrier board 6 can be provided for each of the functional fields 13, each of the LED carrier boards 6 then carrying an LED device 7. However, LED devices 7 of mutually adjacent functional fields 13, for which the LED devices 7 are to be arranged in the same way in relation to the above section 4 in the housing component 2, can also be arranged on a common LED carrier board 6.
This is illustrated by way of example in FIG. 16. Figure 16 (a) shows an LED carrier board 6 which carries nine LED devices 7. The LED devices 7 are arranged in accordance with a 3 × 3 arrangement of the projecting sections 4 in the housing component 2 on the LED carrier board 6. The LED carrier board 6 of FIG. 16 (a) can be arranged as a whole in the housing component 2 of FIG. 1 and attached to a number of the sections 40. In this variant, the LED carrier board 6 is not / 57 in FIG. 16 (a)
Visible rear side 8 in the area of each of the LED devices 7 on the cover surface 5a of the section 4 assigned to the LED device 7, such that each of the LED devices 7 overlaps the cover surface 5a of the assigned section 4 at least in regions. For example, all of the LED devices 7 shown in FIG. 16 (a) can be provided to provide light in the manner of a downlight in each of the functional fields 13 in conjunction with corresponding, possibly different, optical components 16.
FIG. 16 (b) shows a group of four LED devices 7 arranged in a 2 × 2 grid, which are carried by an LED carrier board 6 according to a further variant, while FIG. 16 (c) shows an LED carrier board 6 with a single LED Device 7 illustrated.
Further LED carrier boards 6 are shown in FIGS. 16 (d) and 16 (e), for example for a linear arrangement of three LED devices 7 arranged next to one another in a row or for two LED devices 7 arranged next to one another.
The LED carrier boards 6 shown in FIGS. 16 (a) to 16 (e) are designed to be arranged with their back 8 in sections on the top surface 5a. In other words, these LED carrier boards 6 are placed on the sections 4 from above in FIG. 1.
FIG. 16 also shows in the sub-images (f) to (k) that with sideways, ie. H. Several LED devices 7 can also be arranged on an LED carrier board 6 on the inclined surfaces 5b to 5e in sections on the rear of the LED carrier boards 6, for example to enable wallwasher light fields analogous to the functional field 13b described above. For example, FIG. 16 (f) shows the configuration of an LED carrier board 6 for three LED devices 7 which are to be arranged in a row and which point in the same direction in the finished luminaire 1, in other words, the LED carrier board 6 of FIG. f) can be arranged in such a way in the housing component 2 that this circuit board 6, with its rear side not visible in FIG. 16, sits in sections on an inclined surface 5b-5e of three sections 4 arranged side by side in the housing component 2 such that each of the LED devices 7 overlap the inclined surface of the assigned section 4 at least in regions. The circuit board 6 of FIG. 16 (f) can thus, with its rear side 8, for example in sections in each case on the surface 5b of three / 57 arranged side by side
Mount sections 4, an adapter component 11 then being placed on each of the three sections 4 arranged next to one another.
It can be seen from FIGS. 16 (g) and 16 (h) that an LED carrier board 6 for two LED devices 7 arranged next to one another, as well as for a single LED device 7, which are or must be arranged inclined in the housing component 2 , can be provided in each case.
Furthermore, FIG. 16 shows in sub-images (i) to (k) further circuit boards 6 ', for three or two LED devices 7 arranged next to one another, and for a single LED device 7, analogously to the arrangement of FIGS. 12, 13. For example 16 (d) can also be fastened to three adapter components 11 arranged next to one another.
Each of the LED devices 7 of the lamp 1 is assigned to one of the functional fields 13 and arranged in the respectively assigned functional field 13. Within a luminaire 1, until the housing component 2 is completely equipped, LED carrier boards 6 of various types, as illustrated in FIG. 16, can be combined with one another. A wide variety of lighting requirements can thus be taken into account when configuring the luminaire 1. Some of the functional fields 13 can, for example, emit light in the manner of a downlight, while other functional fields 13 act as wallwashers. Post-processing of housing component 2 is not necessary. Depending on the requirements, the number and / or the cut of the LED carrier boards 6 and, if appropriate, the number of adapter components 11 used can vary.
With reference to FIG. 16, it should also be pointed out that the LED carrier boards 6 can have a cutout 80, the function of which will be explained below.
Although the housing component 2 can be completely filled in such a way that each functional field 13 forms a luminous field, it can be provided in a variant that a sensor device 50 is arranged in one of the functional fields 13 instead of an LED device 7. The sensor device 50 could be provided on a single circuit board specially provided for this purpose, or could be arranged on one of the LED carrier boards 6 instead of an LED device 7. The functional field 13 equipped with the sensor device 50 could also be provided with an optical component adapted to the sensor device 50 and / or with a suitable cover (not shown) adapted to the shape of the functional field 13 and to the function of the sensor device 50. The sensor device 50 can be, for example, a presence / 57
-29 sensor, a brightness sensor, a humidity sensor or a temperature sensor or another desired sensor.
The luminaire 1 is designed as a uniform luminaire which, in the exemplary embodiment shown, has a plurality of light sources which are formed by the LED devices 7 and to which an optical component 16 is assigned in each case. The multiple light sources in the luminaire 1 are flexible, for example individually or in different groups, switchable and / or controllable for generating different lighting effects.
The luminaire 1 has a connection and control unit 17, see FIGS. 1, 5, 6, 8, the connection and control unit 17 having a central control arrangement 25 and a multiplicity of connecting devices 18. The central control arrangement 25 and the connecting devices 18 are arranged, for example, on a control board of the connection and control unit 17. The connecting devices 18 can be set up to produce plug connections. Each of the LED carrier boards 6 can be electrically coupled to the connection and control unit 17 by means of the connecting devices 18.
In the side wall 20c of the housing component 2, a recess 23 is made, which is open to the outside of the housing component 2 and also extends into the base 3. The recess 23 is provided for receiving the flat connection and control unit 17. The connection and control unit 17 is received in the recess 23 in such a way that a main extension plane 24 of the connection and control unit 17, see FIGS. 4 and 5, extends along the side wall 20c. The connection and control unit 17 is thus arranged essentially parallel to the side wall 20c and essentially in a center of the side wall 20c. The connection and control unit 17 is inserted into the recess 23 from the rear 14 and protrudes a bit into the inner region 21. The cutouts 80 of the LED carrier boards 6 create space for the connection and control unit 17. The connection and control unit 17, which has, for example, a housing which carries the control board, does not protrude beyond the side wall 20c on an outside of the housing component 2, but is flush with this.
The central control arrangement 25 can have a DALI module for wired reception of a switching and / or control signal or a ZigBee module for wireless reception of a switching and / or control signal. Electrical current for the operation of the lamp 1 is provided via a connecting line 90 coupled to the connection and control unit 17. The connecting line 90 can also, if switching and / or control signal / 57
-30nale are received by the control arrangement 25 in a wired manner, these switching and / or control signals are provided via corresponding conductors of the connecting line 90.
In the example shown in FIG. 1, there are nine slots on the control board, which form nine connecting devices 18. This enables up to nine plug connections. Thus, up to nine connections can be made, each with an LED carrier board 6 - one of which could be a carrier board for the sensor device 50, in other words, each functional field can have its own LED carrier board 6, which is specifically and separately by means of the Connection devices 18 is connected to the control arrangement 25. The LED carrier boards 6 or LED devices 7 are connected to the connecting devices 18 within the inner region 21 by means of flexible cables. In the case of the assembly 27b of FIGS. 12, 13, the connection between the LED carrier board 6b and the connecting device 18 could alternatively also be established via the board 6 ', which in turn is coupled to the board 6b.
In a variant of the luminaire 1 with great flexibility in the control of individual functional fields 13, the central control arrangement 25 enables a large number of control channels, for example 18 channels. In this variant, the connecting devices 18 are designed, for example, as four-pole plug connections, nine plug connections being provided. In this way, two control channels can be provided for each functional field, one of them for dimming the respective LED device 7, i.e. the control of the light intensity, and the second can be used to control the color temperature of the light emitted by the LED device 7 (“tunable white”). A lamp 1 configured in this way can be configured and controlled in a highly flexible manner. The central control arrangement 25 provides two control channels for each LED device 7. The control channels are controlled flexibly and individually using the central control arrangement 25.
Alternatively, the central control arrangement 25 can be designed to provide 9 channels if only the light intensity of the individual LED devices 7 is to be controlled. In this case too, nine plug connections are provided.
In the exemplary embodiment of the luminaire 1, power electronic components 29 are arranged as a power electronic arrangement 28 together with the LED device 7 or the LED devices 7 on the LED carrier board 6 and thus “brought up” to the LED devices 7. Alternatively, at least some power electronics / 57
Components 29 can be arranged on a further circuit board 6 'in the functional field 13. This is illustrated by way of example in FIGS. 12 and 13 for the carrier board 6b and the further board 6 ', the board 6' also being fastened adjacent to the adapter component 11 in the functional field 13b of the LED carrier board 6b.
By means of the four-pole plug connections, which serve as connecting devices 18, and for example by means of flexible cables, the LED carrier board 6 is coupled to the central control arrangement 25, the four contacts of the plug connections then two contacts for the two control channels, one contact for the supply voltage as well as a contact for the earth. For example, 48 volts are provided as the input supply voltage. In the case of a sensor device 50, the control channels can serve as return channels for the sensor device 50.
The voltage supply brought in via the connecting line 90 is thus connected to a single splitter which further distributes the electrical power and provides a control signal for each control channel.
As described above, the number and design of the LED carrier boards 6 can vary depending on the desired configuration of the lamp 1. Likewise, different numbers of the channels provided can be used in one lamp 1.
The central control arrangement 25 has a data processing device 62, e.g. B. a processor and a storage medium 61. This is indicated purely schematically as an example in FIG. 7.
The LED devices 7 can be dimmed analogously in the light 1 according to the exemplary embodiment described above. Analog dimming with linear controllers is provided for this. Alternatively, switching regulators could be provided.
The assignment of a different number of LED carrier boards 6 at different positions within the housing component 2 to a different number of control channels will be explained in more detail below.
There are different ways to control the LED devices 7. It is not only possible to assign a control channel to each LED carrier board 6, but it is also possible for a plurality of LED devices 7, irrespective of whether they are arranged on a common LED carrier board 6 or on several, to form a single / 57
-32 together controllable group. Furthermore, it is fundamentally also conceivable to address two or more LED devices 7 arranged on a common carrier board 6 via different control channels, provided the LED carrier board is set up for this.
FIGS. 17 and 18 illustrate some possibilities for the configuration of the lamp 1 according to the exemplary embodiment described above.
FIG. 17 (a) shows a configuration of the luminaire 1, in which four functional fields 13, each formed with a wallwasher function, are provided at the corners of the 3 × 3 grid. Two of the wallwasher fields form a controllable group 201, while two further of the wallwasher fields form a further group 203 which can be controlled separately from group 201. Downlight functional fields 13 with an elliptical light distribution are arranged in the middle of the sides of the 3 × 3 grid, which can be controlled together as a group 202. In the middle of the 3 x 3 grid there is an individually controllable functional field 301, which has the function of a downlight with bundled light distribution. In the case of FIG. 17 (a), nine individual LED carrier boards 6 are thus assigned to four control channels, for example, it being assumed that only the light intensity for the individual LED devices 7 is controlled or switched.
In FIG. 17 (b) there are three downlight function fields arranged in a row, each with elliptical light distribution, which are combined to form a group 206 which can be controlled together. A middle row is formed by three downlight function fields combined into a group 205 with a beam angle of 25 degrees, while in the top row in FIG. 17 (b) an individually controllable downlight field 302 between two wallwasher fields combined into a group 204 is arranged.
In the case of FIG. 17 (b), five individual LED carrier boards 6 are thus assigned to four control channels, for example.
FIG. 17 (c) shows a configuration analogous to FIG. 17 (b), in which the fields of groups 205 and 206 shown in FIG. 17 (b) can now be controlled together as group 207. Here, all LED devices 7 of group 207 are arranged on a common LED carrier board 6, as indicated in FIG. 17 (c). Thus, in the configuration of FIG. 17 (c), four individual LED carrier boards 6 are assigned to three control channels.
/ 57
FIG. 17 (d) shows a configuration in which four LED carrier boards 6 are assigned to four control channels. In the upper left corner of the 3 x 3 arrangement in FIG. 17 (d), an individually controllable functional field 303 acting as a downlight is provided, whereas, starting from the lower right corner of the 3 x 3 arrangement, a group 210 of 2 x 2 is common controllable downlight fields with a beam angle of 25 degrees are provided. The remaining functional fields 13 form wallwasher fields which can radiate upwards and to the left in FIG. 17 (d). The wallwasher fields which radiate upwards in FIG. 17 (d) are combined in a group 208, while the wallwasher fields which radiate to the left are combined in a further group 209. Again, the LED devices 7, each grouped in groups 208, 209 and 210, are arranged on a common carrier board 6.
The arrangement of FIG. 17 (e) corresponds to the arrangement of FIG. 17 (d) with regard to the mode of operation of the functional fields 13, but the functional fields 13 combined in FIG. 17 (d) in two separate groups 208 and 209 now in a common group 211 are summarized. The LED devices 7 of the group 211 are nevertheless arranged on two LED carrier boards 6, one for the wallwashers radiating upwards and one for the wallwashers radiating to the left. Four LED carrier boards 6 are thus assigned to three control channels.
In the configuration in FIG. 17 (f), two downlight fields are combined to form a group 212 that can be controlled together, while the LED devices 7 of the remaining function fields 304 to 310 can be individually controlled via an assigned channel. In this case, eight control channels are used. All functional fields are designed as downlight fields, the functional fields of group 212 each producing an elliptical light distribution, fields 304 and 305 a beam angle of 25 degrees, fields 306 and 307 a beam angle of 35 degrees, fields 308 and 309 a beam angle of 45 degrees, and field 310 produce a highly focused light distribution.
The configuration shown in FIG. 18 corresponds to that of FIG. 17 (f), but the functional field 310 arranged centrally in FIG. 17 (f) is used differently. In the middle of the 3 × 3 grid, a circuit board (not shown in detail) with a sensor device 50 is arranged in FIG.
The luminaire 1 not only enables the configurations shown in FIGS. 17 and 18, but also offers many other configuration options.
/ 57
In a method for producing the luminaire 1 according to the exemplary embodiment described above, the procedure is, for example, as follows:
A customer, for example a lighting designer, configures the luminaire 1, for example with software provided specifically for this purpose, which the customer can download, for example, via a data network, for example the Internet, or operate directly via the data network.
For example, the customer first selects the size of the desired luminaire, for example a luminaire size that enables a 3 × 3 grid as in FIG. 1. Other sizes of the luminaire can also be selected, for example several function fields in a row, or a grid of function fields in the manner of a 2 x 2 or 3 x 2 grid.
The customer then configures the functional fields 13, in other words, he selects which light effect or which light distribution the functional field 13 is to provide in each case. If a sensor is to be installed, the customer also selects this.
The customer must then specify the desired control options, for example to what extent the functional fields should be controllable separately or together in groups and whether only the intensity or the color of the light should be controllable.
Depending on the aforementioned configuration data specified by the customer in the course of the configuration of the luminaire, a housing component 2, as explained above, is provided and, for example also with the aid of the software, the suitable number and type of LED carrier boards 6 are determined. Depending on the configuration data, these can then be installed in the housing component 2 with the appropriate optical components 16 and, if necessary, adapter components 11. The necessary connections to the central control arrangement 25 are made by means of flexible cables.
The software can also be used to provide, generate or configure a program that can be executed by means of the data processing device 62 of the control arrangement 25, again depending on the configuration data specified by the customer, the program then being loaded onto the storage medium 61 of the control arrangement 25. The control of the functional fields 13 can be effected or modified by means of the program. For example, the same control arrangement 25 can be used for differently configured lamps 1, the functions of which are suitably adapted by loading the program.
/ 57
In the exemplary embodiment, the LED devices 7 can be connected in parallel in order to be able to control them separately. The aforementioned program (firmware) can set a maximum control current for each group channel that addresses a control group, in order to ensure that all light sources can deliver the same light intensity in the desired manner.
In a variant of the exemplary embodiment described above, the activation of the LED devices 17 of the functional fields 13 of the lamp 1 can be implemented in a simplified manner. While the exemplary embodiment described above is highly flexible and very versatile in terms of the possible lighting effects, in a simplified embodiment, for example if simpler lighting effects and lower costs are desired, the luminaire 1 can be constructed without the central control arrangement 25. While the mechanical, optical and thermal concept explained for the exemplary embodiment described above remains unchanged, the LED devices 7 in the simplified variant are supplied via an external converter 30, which can be arranged, for example, in the connecting line 90. See the schematic representation in FIG. 19. The converter 30 can be a DALI converter with one or two output channels, thereby providing a more cost-effective control with reduced complexity for simpler applications.
In the case of such a simplified variant, all functional fields 13 could be designed, for example, as downlights or as wallwashers, although a combined arrangement of downlights and wallwashers is also possible in the simplified variant described above with control via the external converter 30.
In the simplified variant with the external converter 30, the power electronic components 29 or arrangements 28 on the LED carrier boards 6 are also omitted. In this case, the electrical current for supplying the LED devices 7 is supplied directly by the external converter 30, in which case the connection and control unit 17 of the embodiment described above in the simplified variant now forms a connection unit 17 which, for. B. only has a strain relief for the connecting line 90 and plug connections for connecting the LED carrier boards 6 via flexible cables.
In further variants, a reduced number of channels could be provided, starting from the exemplary embodiment described above with a central control arrangement 25, at / 57
-36 for example for simpler applications, in which several individually controllable lighting effects should nevertheless be combined in lamp 1. In such a case, the number of control channels could be less than nine, for example four or eight.
The luminaire 1 thus enables the display of different lighting effects and different light scenes as well as the illumination of a large area of space with a very compact design of the luminaire 1 by means of the flexible control. This is achieved without mechanical adjustment of individual light sources being provided. A flexible and modular coupling of different numbers of LED carrier boards 6 is possible. Furthermore, it becomes possible to arrange different optical components 16, for example different reflectors, at different positions in a uniform, single housing component 2 in a selectable combination without the housing component 2 having to be modified subsequently. For each size of the luminaire 1, that is to say for a given number and geometrical arrangement of functional fields 13, only one housing component 2 of a single type is to be produced, which advantageously reduces the costs for die casting tools and the variety of components. The housing component 2 is also optimized with regard to heat dissipation and enables efficient cooling of the LED devices 7. The luminaire 1 has a low height and thus also a comparatively small space requirement. The voltage supply and the control of the LED devices 7 succeed in a space-saving manner.
Although the invention has been completely described above on the basis of preferred exemplary embodiments, it is not restricted to these but can be modified in a variety of ways.
