    SUMMARY OF THE INVENTION
    Against this background, the invention is based on the object of providing a luminaire which avoids the above-mentioned disadvantages of conventional lighting devices and offers improved lighting options in order to illuminate the areas or objects to be illuminated in a more targeted and efficient manner and to meet the aesthetic requirements of the light effect achieved in a variety of situations flexible to meet.
    According to the invention, this object is achieved by a lamp with the features of patent claim 1.
    Accordingly, a luminaire is proposed which has a luminaire base body and luminaire segments which can be inserted into the luminaire base body. It is provided here that each of the light segments emits light in a directed manner and has a predefined emission characteristic. Here, the radiation characteristics of the light segments comprise at least two different radiation characteristics.
    One finding on which the present invention is based is that the light emitted by the light segments can be used more efficiently in this way than when using conventional spotlights. In particular, it is possible to illuminate specifically desired areas, to avoid direct lighting of areas that are not to be illuminated, and to achieve different aesthetic lighting effects in a flexible manner, for example in order to stage a room and / or an object and / or a person in different ways , Furthermore, luminaires can be saved by the more efficient, more effective emission of light, and more efficient use of the emitted light can also offer the advantageous possibility of saving energy. In particular, a luminaire can therefore be created according to a modular principle. In other words, in particular, a flexibly usable luminaire system of modular design is provided, which comprises the luminaire base body and the luminaire segments.

    -3 In the present case, a radiation characteristic is to be understood as the directed light output (quantity) emitted by a light segment. The term “radiation characteristic” should in particular also be understood to mean that simply twisting or swiveling and otherwise repositioning a light segment does not change its radiation characteristic.
    Advantageous refinements and developments result from the subclaims and from the description with reference to the figures of the drawing.
    In one embodiment, at least two light segments can be inserted into the light base body. The luminaire base body is designed to insert at least two luminaire segments into it. In particular, when using the lamp, the user can insert the total number of at least two or more lamp segments that can be inserted into the lamp base body for some applications, whereas for other applications, the user can insert fewer lamp segments into the lamp base body than the design of the lamp base body makes possible. A very flexible use of the lamp is possible thanks to this modular design. For example, a subsequent adjustment of the luminaire can easily be carried out in the case of redesigns, for example in a business premises.
    In one configuration, the light segments can be inserted into the light base body at predefined, for example regularly arranged, positions. This allows a high degree of flexibility when equipping the luminaire base body, for example with a selection from a total of available luminaire segments. In particular, light segments that are essentially identical in terms of their outer shape can thus be flexibly combined.
    In one development, the light segments can be insertable, for example, at positions which are specified by a regular grid, for example with grid lines crossing at right angles.
    / 53
    In one embodiment, the light segments can be inserted into the light base body in such a way that the inserted light segments form an arrangement extending in one plane, in particular in a horizontal or vertical plane when the light is in an assembled state. In this way, a variety of light effects can be achieved for the individual light segments by means of the emission characteristics of the light segments without complicated rotating and pivoting mechanisms. For example, if the level is essentially horizontal when the luminaire is installed, floor areas, wall areas or both can be illuminated, but the luminaire segments do not have to be adjusted by pivoting or twisting, but can preferably be arranged in a fixed orientation and from the horizontal out light. In an analogous manner, lighting effects can optionally be generated in floor, wall and / or ceiling areas if the plane is essentially vertical, in which case the preferably firmly aligned light segments shine out from the vertical. In particular, by arranging the light segments in accordance with this configuration, the light can be used to achieve light effects, for example, both in horizontal and in vertical subregions of a room. The generation of such light effects with an arrangement of light segments extending essentially in one plane can achieve an interesting aesthetic effect and can also be advantageous, for example, when the light is used in a grid ceiling.
    For example, the arrangement can be formed in such a way that the light segments in the horizontal or vertical plane, for example, are inserted next to one another in a row or in two directions in a matrix-like manner in the light base body.
    In one embodiment, in the assembled state of the lamp, the plane in which the arrangement extends can run essentially parallel to a ceiling or essentially parallel to a wall of a room.
    In a further embodiment, two or more of the inserted light segments can have the same radiation characteristic. For example, this can be done / 53
    -5chen to provide several similar lighting effects or a larger lighting effect of a kind.
    In one embodiment, the light segments each have an optical component, the use of which in each case achieves the emission characteristic of the light segment. In one development, the luminaire can in particular be equipped with luminaire segments in such a way that the luminaire has such optical components of at least two differently designed types. In this way, it is possible to provide different radiation characteristics in an expedient manner.
    In one embodiment, at least one of the light segments has a reflector as an optical component, or several or all of the light segments each have a reflector as an optical component, the reflector preferably having at least one light-reflecting partial surface designed as a free-form surface. In a further development of this configuration, at least one of a plurality of light-reflecting partial surfaces of the reflector is designed as a standard reflector surface or as part of a standard reflector surface and at least one as a free-form surface. In this way, the radiation characteristic of the light segment can be influenced effectively, and the reflector can advantageously be designed with comparatively small dimensions.
    A standard reflector surface can be, for example, a reflector surface of parabolic shape, in particular a reflector surface of parabolic shape with a facet structure. The standard reflector surface could therefore be, for example, a paraboloid surface or part of one, possibly with a facet structure.
    A free-form surface, on the other hand, can be designed freely in order to specifically influence the reflection process on the light-reflecting partial surface designed as a free-form surface and to change or optimize the light distribution achieved and thus the radiation characteristic.
    / 53
    Thus, in one embodiment, the lamp can be equipped with light segments in such a way that the lamp has reflectors of at least two different types. This advantageously enables different radiation characteristics and different lighting effects. In another embodiment, however, several of the reflectors can be of the same type.
    In one embodiment, at least two of the light-reflecting partial surfaces are each designed as a standard reflector surface or as part of a standard reflector surface and at least two of the light-reflecting partial surfaces are each designed as a free-form surface.
    According to a further development, the reflector has two light-reflecting partial surfaces each designed as a standard reflector surface or as part of a standard reflector surface, which are arranged opposite one another. Furthermore, the reflector here has two light-reflecting partial surfaces designed as free-form surfaces, which are arranged opposite one another. This can be useful, for example, to create a rather elongated cone of light for illuminating elongated areas, such as aisles.
    In one configuration, the reflector is designed with four light-reflecting sides. Such a reflector can harmoniously form part of a four-sided light segment.
    In one embodiment, adjacent ones of the light-reflecting partial surfaces are connected to one another at one of several corners of the reflector. A shape of the reflector with several corners can in turn contribute to the setting of the desired radiation characteristic.
    In one embodiment, at least one of the free-form surfaces is bulged in the manner of a bulb toward an inner reflector region. This can also be advantageous for generating a light distribution that is to be adapted to an area that is to be illuminated, for example, rather elongated.
    / 53
    In one configuration, the reflector is designed as an injection molded part. Here, the reflector can also have, for example, a reflective layer connected to the injection molded component. Such a reflector can be produced comparatively inexpensively, even if the reflector has a complex shape.
    In other configurations of the invention, the reflector can be manufactured by means of another manufacturing method. For example, the reflector can be produced by forming a metal sheet, for example using one or more of the following processes: roll forming or cold rolling, bending, stretch drawing, drawing processes such as, in particular, deep drawing, pressing, embossing, punching, shaping - for example deep drawing - using a rubber cushion, Pressing, superplastic forming, hammering or driving, explosion forms, magnetic pulse shaping.
    In particular, a further development provides that the shape of the reflector cannot be changed by a user, but is fixed. In embodiments of the invention, however, a number of light segments, each with a different reflector shape, are preferably provided for different applications and / or effects, the reflector shape thus being provided by a corresponding choice of the light segments when the configuration of the light is put together for the first time or by later replacement of the light segments Demand can be varied. This eliminates the need for complicated and time-consuming adjustment processes. Instead, the luminaire can advantageously be configured by a customer in a suitable manner for the intended use, for example, by appropriately combining luminaire segments with different emission characteristics.
    In particular, in embodiments of the invention, a plurality of luminaire segments can be combined in one luminaire, which have different reflectors, each with at least one light-reflecting partial surface designed as a free-form surface.
    In one embodiment, a plurality of reflectors with the same outer contour are advantageously provided, but each of the light segments is un / 53
    -8 give different radiation characteristics. Luminous segments with a wide range of radiation characteristics can thus be offered, which can be selected by a customer as required and inserted into the luminaire base. Due to the same outer contour of the reflector, such light segments fit well together, both in terms of the space required in the base of the luminaire and with regard to the aesthetic effect. In further refinements, for example, the reflectors of all light segments can have an essentially identical outer contour. This can be particularly practical and useful from an aesthetic point of view and when inserting the light segments. Alternatively, the light segments of the light can form groups within which the outer contour of the reflectors is the same.
    In embodiments, the outer contour of the reflector can be, for example, square, in particular square, or round, in particular circular. Combinations of reflectors with square and round outer contours are also conceivable.
    In one embodiment, at least one of the light segments has a lens as an optical component, or several or all of the light segments each have a lens as an optical component. An effective influencing of the radiation characteristics of the light segment can also be achieved by means of a lens.
    In a further embodiment, the lamp can be equipped with light segments in such a way that the lamp has lenses of at least two different types. This in turn advantageously enables different radiation characteristics and different lighting effects. In another embodiment, however, several of the lenses can be of the same type.
    According to a further development, it can in particular be provided that the shape of the lens cannot be changed by a user, but is fixed. In embodiments of the invention, a number of light segments, each with a lens having a different effect, for example a different lens shape, are preferably provided for different applications and / or effects. The lens type / 53
    -9therefore can be varied by a corresponding choice of the light segments when the configuration of the light is put together for the first time or by later replacement of the light segments if necessary. Complicated and time-consuming adjustment processes are thus eliminated, and the luminaire can instead be advantageously configured by a customer, for example, when the order is placed, for the desired purpose, for example by appropriately combining luminaire segments with different emission characteristics.
    In particular, in embodiments of the invention, a plurality of luminaire segments can be combined in one luminaire, which have differently shaped lenses.
    In one embodiment, a plurality of lenses with the same outer contour are advantageously provided, each of which gives the light segments a different radiation characteristic. Thus, when designing the optical component as a lens, light segments with a wide variety of radiation characteristics can also be offered, which can be selected by a customer as required and inserted into the light base body. Due to the same outer contour of the lens, such light segments fit well together, both in terms of the space required in the base of the luminaire and in terms of the aesthetic effect. In further refinements, for example, the lenses of all the light segments can have an essentially identical outer contour. This can be particularly practical and useful from an aesthetic point of view and when inserting the light segments. Alternatively, the light segments of the light can form groups within which the outer contour of the lenses is the same.
    In embodiments, the outer contour of the lens can be, for example, square, in particular square, or round, in particular circular. Combinations of lenses with square and round outer contours are also conceivable.
    In a further development, the lens can be a lens, the effect of which is largely based on total internal reflection (so-called TIR lens in English, where TIR stands for "total internal reflection").
    / 53
    In a further embodiment of the invention, at least one of the light segments can have a lens as an optical component, while at least one further of the light segments has a reflector as an optical component. In particular, the reflector has at least one light-reflecting partial surface designed as a free-form surface. According to this embodiment, at least one light segment with a lens is thus combined with at least one light segment with a reflector. This can have an even more advantageous effect on the variety of light effects that can be produced.
    In one embodiment, the light segments are designed as interchangeable light segments. Thus, one or more light segments can advantageously be exchanged in order to replace the light segment (s) with one or more light segments with a different radiation characteristic and to vary the light effects that can be achieved. In addition, a possibly damaged light segment can be easily replaced in this way.
    For example, the light segments can be designed as exchangeable spots. The interchangeability not only enables the replacement of a light segment in the event of damage, but also a certain changeability of the light in the event of changes, for example in an environment to be illuminated by means of the spots. Light effects can thus be varied in a simple manner, e.g. the lighting function of the lamp can be influenced in many ways by changing the lighting segments.
    For example, the luminaire base body can be rectangular, in particular square, in one embodiment. A rectangular or square luminaire base body can be useful, for example, if the luminaire is to be installed in a grid in a false ceiling.
    In one configuration, for example, four to nine light segments or four to sixteen light segments can be inserted into the light base body. In particular, a right-angled grid with 2 x 2 insertion positions for light segments or with 3 x 3 such insertion positions or with 4 x 4 such insertion positions can be provided. In further training courses, however, are / 53
    11 such grids with η x n or n x m positions are generally conceivable, where n and m each represent an integer.
    In one configuration, the luminaire as a whole can be finely adjustable, for example by finely adjusting the angular position of the entire luminaire within a limited angular range. This can be useful, for example, to make a fine adjustment or fine adjustment of the lighting effect achieved after mounting the luminaire and to compensate for any installation tolerances.
    In a preferred embodiment, the light segments are inserted into the light base body at fixed positions and also in relation to the light base body after insertion so that the structure of the light is simplified and the light can be produced more cost-effectively. However, in a further development it is conceivable to design the light segments to be insertable into the light base body in one of several defined angular positions, for example rotated in steps of 90 degrees.
    In one embodiment, the light output of the light segments can be switched and / or controlled specifically for individual light segments and / or for subgroups of the light segments, such that different light effects can be achieved by means of the light. In particular, a wide variety of possibilities are conceivable here to switch on or off light segments individually or in combination with one another or to control the light emission thereof in order to make the most varied lighting effects possible.
    According to a development, the light output of the light segments can be switched and / or controlled in such a way that a plurality of light segments, in particular a plurality of light segments of the same design, of a first subgroup of the light segments can be activated simultaneously for emitting light, in order to achieve a first by interaction of the light segments of the first subgroup To produce a light effect, and that furthermore a plurality of light segments, in particular a plurality of light segments of the same design, of a further subgroup of the light segments can be activated simultaneously to emit light, in order to produce a further light effect by the interaction of the light segments of the further subgroup.
    / 53
    The further light effect is different from the first light effect. In this way, different lighting effects can be effectively achieved by means of lighting segments adapted for this purpose. In a modification, some or all of the light segments combined in a subgroup can be designed differently if this is useful for generating the desired light effect.
    In a further development, the first and second subgroups of the light segments are disjoint. According to an alternative further development, however, the first and second subgroups can instead comprise one or more common light segments.
    In further refinements, more than two subgroups of light segments can be provided to produce further light effects, for example three or four subgroups or even more.
    In one embodiment, the light effects include targeted, in particular direct, lighting of a wall or a predefined area of a wall, and / or targeted, in particular direct, lighting of a floor or a predefined area of a floor, and / or targeted, in particular direct, Illumination of an object placed in a room or a person in a room.
    It can thus be provided in one embodiment of the invention that the wall or the predefined region of the wall can be illuminated by means of a subgroup of several identically designed light segments, while the floor or the predefined one can be illuminated by another subgroup of differently, but mutually identically designed, light segments Area of the floor can be illuminated, the two subgroups can be used in combination for simultaneous lighting in the wall and floor area by appropriate switching and / or controlling the light segments.
    In other configurations, however, it can be provided that the lighting of the wall or the predefined area of the wall and / or the lighting of the floor or the predefined area of the floor and / or the lighting of the / 53
    -13 in the object placed in the room or by the person in the room by means of a single light segment each associated with the light effect.
    In a further embodiment, the light effects include targeted, in particular direct, lighting of a wall or a predefined area of a wall, and / or targeted, in particular direct, lighting of a floor or a predefined area of a floor, and / or targeted, in particular direct Illumination of a ceiling or a predefined area of a ceiling and / or targeted, in particular direct, illumination of an object placed in a room or a person in a room.
    It can thus be provided in a further embodiment of the invention that the wall or the predefined area of the wall can be illuminated by means of a subgroup of several identically designed light segments, while the floor or the base can be illuminated by means of a further subgroup of differently, but mutually identical, light segments predefined area of the floor can be illuminated, while the ceiling or the predefined area of the ceiling can be illuminated by means of yet another subgroup of, for example, different, but again identical lighting segments. By switching and / or controlling the light segments accordingly, the sub-groups can be used in combination for simultaneous lighting in the wall, floor and ceiling area.
    In other configurations, however, it can be provided that the lighting of the wall or the predefined area of the wall and / or the lighting of the floor or the predefined area of the floor and / or the lighting of the ceiling or the predefined area of the ceiling and / or the lighting of the object placed in the room or of the person in the room by means of a single light segment each assigned to the light effect.
    In a further development, the producibility of one or more of the light effects can be created by means of a single one of the light segments with the producibility of another
    -14ren or several other of the lighting effects can be combined by means of a subset of the lighting segments.
    In one embodiment, the light segments each have a device which makes it possible to receive control signals for switching and / or controlling the light output of the light segment in a wireless or wired way. In a further development, devices can be provided which enable the control signals to be received both by wire and by wireless means. Here, the light segments are set up to switch and / or control the light output in accordance with the control signals. In this way it is possible to address the lighting segments in a flexible manner and at the same time to limit the wiring effort.
    In one embodiment, the light segments each have a communication device which enables the control signals to be received by wireless means and in particular comprises an interface for communication via a wireless protocol. Alternatively or additionally, the light segments can each have an interface for connection to a wired bus or a wired network, which enables the control signals to be received.
    In one configuration, an outer contour of at least one of the light segments, some of the light segments or all of the light segments is polygonal, in particular rectangular or square. Alternatively, an outer contour of at least one of the light segments, some of the light segments or all of the light segments can be round, in particular circular. In a further alternative embodiment, an outer contour of at least one of the light segments is round, in particular circular, and an outer contour of at least one other of the light segments is polygonal, in particular rectangular or square. For example, an interesting aesthetic effect can be achieved if the light segments all have a relatively simple, for example the same, outer contour, but differ in their radiation characteristics. A rectangular outer contour can also be advantageous in order to insert a multiplicity of light segments into a substantially rectangular light base body.
    / 53
    In further developments of the invention, the lamp can be designed for arranging the lamp in the ceiling area and / or for arranging the lamp in the wall area.
    In one configuration, the luminaire is designed as a grid luminaire for arrangement in a grid ceiling. It is thus advantageously possible to provide lighting effects in a flexible and versatile manner even in cases in which the arrangement and fastening of the luminaire are based, for example, on the grid of a grid ceiling.
    In an alternative embodiment, the lamp is designed as a recessed lamp. Here, the luminaire can be provided and set up, for example, for installation in a ceiling and / or for installation in a wall.
    According to a further alternative embodiment, the luminaire is designed for use as a suspended luminaire, the luminaire being able, for example, to have an independent housing for use as a suspended luminaire.
    In a further alternative embodiment, the luminaire is designed for mounting on a wall. For this purpose, the lamp can in particular have an independent housing, which makes it possible to arrange the lamp in the wall area on the surface of the wall. Alternatively, the luminaire could be designed for mounting on a surface of a ceiling and in particular have an independent housing which is set up for arranging the luminaire on the surface of the ceiling.
    In this way, a wide variety of lighting requirements can be met.
    In one embodiment, the light segments are each equipped with an LED or an LED arrangement for generating light. In this way, an energy-efficient and long-lasting luminaire can be provided.

    The above configurations and further 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.

They illustrate embodiments and, in conjunction with the description, serve to explain principles and concepts of the invention. Other embodiments and many of the advantages mentioned result from the drawings. The elements of the drawings are not necessarily shown to scale with respect to one another.
    In the figures of the drawings, elements, features and components that are the same, have the same function or have the same effect — unless otherwise stated — are each provided with the same reference symbols.
    DESCRIPTION OF EMBODIMENTS
    Fig. 1 shows a lamp 1 according to a first embodiment. Furthermore, FIG. 1 shows a room 2 in a building which is not shown in its entirety, the room 2 having a relatively narrow and elongated shape in the exemplary embodiment shown. Room 2 can be, for example, a corridor inside the building. Room 2 can also be / 53
    -19 act a different kind of space, for example an office space, a business space, etc. The room 2 has a grid ceiling 3, which forms a suspended false ceiling. Furthermore, the room 2 has a first wall 4a, a second wall 4b and a floor 5. The lamp 1 is designed as a grid lamp for mounting in the grid ceiling 3 and is fastened in the grid ceiling 3, which is not shown in detail in FIG. 1 but only indicated.
    The luminaire 1 has a square luminaire base body 6 and a plurality of luminaire segments 7 and 8 which can be inserted into the luminaire base body 6, the luminaire segments 7 and 8 being inserted into the luminaire base body 6 at predefined positions 7a and 8a, see also FIG. 1A , For the sake of a better overview, not all of the light segments and positions are provided with reference numerals in FIGS. 1 and 1A. For example, the luminaire 1 of FIGS. 1, 1A has four luminescent segments 8 and twelve luminescent segments 7. An outer contour 9 of each of the light segments 7 is square in FIG. 1. In contrast, an outer contour 10 of each of the light segments 8 is circular. The outer contours 9 of the light segments 7 and the outer contours 10 of the light segments 8 are each of the same design.
    1 and 1A also show that the positions 7a of the light segments 7 and the positions 8a of the light segments 8 are each arranged regularly. While the light segments 8 are arranged along a straight line, the light segments 7 are arranged at positions 7a which correspond to the crossing points of an orthogonal grid. In the first exemplary embodiment, however, positions 8a also form further intersection points of the grid which already defines positions 7a, see FIG. 1A.
    In their inserted state, the light segments 7 and 8 thus form an arrangement 80, see FIGS. 1A and 2, which extends in a plane E. 1, 1A and 2 in the assembled state of the lamp 1 shown there, it runs horizontally and parallel to a plane in which the grid ceiling 3 extends, whereby the plane E and the plane of the grid ceiling 3 can coincide. A direction H which is horizontal with respect to space 2 is shown in FIG. 1 for clarification. The plane E is thus, see FIGS. 1A and 2, through two directions RI, R2 on / 53
    Stretched, which in FIG. 1A run perpendicular to one another and parallel to the grid ceiling 3, or in the plane of the grid ceiling 3.
    The light segments 7 and 8 are each designed to be inserted into the light base body 6 and thereby be releasably inserted therein. For example, the light segments 7, 8 and / or the light base body 6 can be provided with suitable latching devices, by means of which it can be achieved that the light segments 7 and 8 each snap into the light base body 6 when inserted and are thus held, in particular releasably. It can be provided here that the latching insertion of the light segments 7, 8 in each case in several rotational positions, for example in several positions rotated about an axis parallel to the vertical axis V, and in particular normal to the plane E, is made possible by the center point of the light segment. Latching insertion could be possible in a plurality of steps, offset by a predefined angle, e.g. in 90 degree increments.
    In the first exemplary embodiment, the light segments 7 and 8 are designed as exchangeable spotlights, in particular spots. Each of the light segments 7, 8 thus emits light in a directed manner and has a predefined radiation characteristic. However, the radiation characteristics of the light segments 7, 8 of the light 1 are not all identical, but the total amount of the radiation characteristics of the light segments 7, 8 comprises several different radiation characteristics.
    Each of the light segments 7, 8 has one or more light sources, which allow the directional emission of light by the light segments 7, 8. The light output of the light segments 7, 8 in the light 1 of FIG. 1 can be switched and / or controlled in a targeted manner at least in the manner illustrated schematically in FIGS. 1 to 4 in order to generate a number of different light effects. Switching and / or controlling the light output of a light segment 7, 8 can in particular include completely switching off the light segment, switching it on at full power, and, if necessary, switching on the light segment at a predefined power level below full power. Furthermore, / 53
    The switching and / or controlling of the light output additionally comprise a continuous regulation of the light output in the sense of dimming.
    In Fig. 1, the provision of a first light effect 11 by means of the lamp 1 according to the first embodiment is schematically outlined. For this purpose, two light segments 7, which are additionally provided with the reference symbol 7 'for better identification, were activated, while the other light segments 7, 8 are switched off. The two light segments 7 'each have a radiation characteristic which makes it possible to use the two light segments 7' to jointly generate a light distribution which enables direct illumination of a predefined region 11a of the floor 5 of the aisle 2. For this it is useful if the light segments 7 'produce an elongated light distribution which is better adapted to the elongated shape of the room 2 than a circular light cone. Efficient illumination is thus possible with one lamp 1.
    In FIG. 2, instead of the light segments 7 ', a single light segment 7, identified by the reference number 7 in FIG. 2, has been activated, while the other light segments 7, 8 are switched off. The radiation characteristic of the light segment 7 differs from that of the light segments 7 '. The light segment 7 produces a round, for example circular or elliptical, light distribution in a region 12a on the base 5 as a second light effect 12. In contrast to, for example, larger-area illumination of the base 5, as in FIG. 1, the light effect in FIG. 2 12 creates a different mood and the room 2 differs from that in Fig.
    staged. In FIG. 2, a smaller and differently shaped predefined area 12a of the base 5 is illuminated directly than in FIG. 1. There may optionally be an object 0 in the room, shown in dashed lines in FIG. 2, which stands, for example, on the floor 5 and is particularly illuminated and staged by means of the light effect 12. Instead of object 0, a person in room 2 could be illuminated by means of activated light segment 7.
    In FIG. 3, two of the light segments 8 identified by the reference symbol 8 'and two of the light segments 7 identified by the reference symbol 7' are activated in order to generate a third light effect 13. The third light effect 13 includes two individual light effects 13 'and 13 and includes direct lighting / 53
    22 of both walls 4a, 4b of room 2 in rather elongated illuminated areas 13a, 13b, but without the floor 5 being deliberately illuminated directly. This in turn creates a different mood in room 2. If available, objects on the walls can be illuminated, or only the wall surface and structure are illuminated in order to highlight room 2.
    4, the light output of the light segments 7, 8 of the light 1 is switched and / or controlled in such a way that the lighting effects schematically outlined in FIGS. 1, 2 and 3 are combined and thus form a fourth light effect 14. The fourth light effect 14 thus combines the direct illumination of the walls 4a, 4b as in FIG. 3 with the illumination of the floor 5 according to FIG. 1 and with an increased illumination of a circular or elliptical area 12a of the floor 5, within that by means of the light segments 7 'already illuminated floor area 11a.
    In order to generate the light effects 11-14 which are illustrated schematically in FIGS. 1, 2, 3 and 4, individual light segments 7, 8 of light 1 or subgroups of light segments 7, 8 are specifically switched on or off or their light output is controlled in a targeted manner.
    In Fig. 1, the light segments 7 ', which can be of identical design, form a first sub-group 21 of light segments 7, which are activated at the same time in order to produce the first light effect 11 by the interaction of the light segments 7' of the first sub-group 21. In contrast, a single light segment 7 was activated in FIG. 2 to generate the second light effect 12.
    In FIG. 3, the light segments of a second subgroup 22, which comprises two light segments 8 'and two light segments 7', see FIG. 3, were activated simultaneously to produce the third light effect 13, a third subgroup 22a comprising the two, for example, similar light segments 8 ', the illumination of the area 13a on the first wall 4a and a fourth sub-group 22b, comprising the two, for example, similar light segments 7, the area 13b on the second wall 4b is illuminated. Thus, the / 53
    -23Luminous segments 8 'of the third sub-group 22a jointly produce the light effect 13' on the first wall 4a, while the luminous segments 7 'of the fourth sub-group 22b jointly produce the light effect 13 on the second wall 4b. The third light effect 13 is formed by the interaction of the light effects 13 ', 13.
    4, the subgroups 21, 22a, 22b and the light segment 7 are activated at the same time in order to provide the light effect 14. The light segments 8 ', 7', 7, 7 form the fourth sub-group 23, which is schematically outlined in FIG. 4.
    1-4 it is clear that the light effects 11, 12, 13 'and 13 are different from each other. The light effects 13 and 14 also differ from the individual light effects 11, 12, 13 ', 13 in that new or different lighting effects are created by combining some or all of the light effects 11, 12, 13', 13. The subgroups 21, 22a, 22b are disjoint and thus do not contain any common light segments, whereas the subgroups 21, 22a and 22b are all contained in the fifth subgroup 23.
    It can thus be seen that the luminaire 1 advantageously enables the generation of light effects, in particular in vertical and horizontal subregions or areas of the room 2, for example in the area of the floor 5 and the walls 4a, 4b, without pivoting or to vary the light effects Twisting spots would be necessary. The light segments 7, 8 radiate out of the horizontally extending arrangement 80 into the space 2, for example onto one or more areas of the walls 4a and / or 4b or the entire wall 4a and / or 4b, and alternatively or in combination with this on one or more area (s) of the floor 5 or the entire floor 5. Thus, with a permanently mounted lamp 1 with a fixed arrangement 80 of the light segments 7, 8 horizontally laid out in the mounted state, a wide variety of lighting effects in the horizontal and in particular in the vertical can be generated. The light effects are varied in a simple manner by switching and / or controlling the light output from individual light segments 7, 8 or from groups of these.
    According to the first exemplary embodiment, each of the light segments 7 and 8 has an optical component 25 designed as a reflector 30, below which / 53
    Use in each case the radiation characteristic of the light segment 7, 8 is achieved. In order to achieve different radiation characteristics, the light 1 is equipped with light segments 7 and 8 in such a way that the light 1 contains different reflectors 30 of this type. The luminaire 1 has luminaire segments 7, 8 with at least two different types of reflectors for generating at least two different emission characteristics in order to be able to provide different lighting effects.
    5 and 5A schematically show a reflector 30 for a light segment 7 of the light 1 according to the first embodiment. The light segment 7 can be, for example, one of the light segments 7 'of the first subgroup 21.
    The reflector 30 is manufactured, for example, by means of injection molding and has a plurality of light-reflecting partial surfaces 31, 32, 33, 34, 35, 36, 37, 38. Instead, the reflector 30 could alternatively be produced by means of another manufacturing method, for example by reshaping a sheet metal blank. The two light-reflecting partial surfaces 31 and 33 are arranged opposite one another and are each designed as part of a standard reflector surface. Furthermore, the two light-reflecting partial surfaces 32 and 34 are arranged opposite one another and are each designed as a free-form surface. The free-form surfaces 32 and 34 can be used to influence the radiation characteristic of the light segment which is equipped with the reflector 30 in a targeted manner.
    A light source 49 is also schematically shown in FIG. 5, which in this exemplary embodiment is designed as an LED arrangement 50 with a plurality of light-emitting diodes (LEDs) 51. The LED arrangement 50, like the reflector 30, forms part of a light segment and is, for example, square in FIG. 5, but it should be mentioned that the light source 49 can also be shaped differently, for example round. Instead of LEDs, other light sources, such as halogen lamps, are also conceivable.
    Furthermore, in FIG. 5, a visible side S of the reflector 30 facing the room 2 in the inserted state of the light base body 6 is 53
    -25tet. The reflector 30 opens to the visible side S in order to emit the light with the desired radiation characteristic. 5A shows the reflector 30 schematically in a top view from the visible side S.
    The reflector 30 has four light-reflecting sides 30a, 30b, 30c, 30d, adjacent ones of the light-reflecting partial surfaces 31-38 being connected to one another at one of a plurality of corners 39a-39d of the reflector 30. In detail, the partial areas 31 and 32 and 35 and 36 are each connected to one another at the corner 39a, the partial areas 32 and 33 and 36 and 37 are each connected to one another at the corner 39b, the partial areas 33 and 34 as well as 37 and 38 are each on of the corner 39c and the sub-areas 34 and 31 and 38 and 35 are each connected at the corner 39d. The reference symbol 30u designates the substantially rectangular, in particular square, outer contour of the reflector 30.
    FIG. 5 also shows a central axis A of the reflector 30. The light-reflecting partial areas 31-38 enclose an inner reflector area 40, which runs towards the LED arrangement 50 in the manner of a funnel, but with an angular cross-sectional shape with the four corners 39a-d. The light-reflecting partial surfaces 35-38 arranged further towards the visible side S are more inclined to the central axis A, are therefore flatter when viewed from the visible side S, and together form a considerably larger opening angle than the light-reflecting partial surfaces 31-34.
    The partial surfaces 32 and 34, which are designed as free-form surfaces, are bulged toward the inside of the reflector 40. The bulbous protrusion is designated by reference numeral 45 in FIGS. 5 and 5A. Such a design of the free-form surfaces 32, 34 is particularly useful in order to adapt the light distribution and radiation characteristic of a light segment which has the reflector 30 to an elongated area to be illuminated, for example. 6 and 7 schematically illustrate a light cone 60, as can be generated by means of a reflector 30 with light-reflecting partial areas 31-38 according to FIGS. 5, 5A, in two directions normal to one another. 6 shows a schematic side view of the light cone 60, while FIG. 7 shows it from the front. It is clear that the light cone 60 is different in the two viewing directions / 53
    -26 is shaped and, as is particularly clear from FIG. 7, has an elongated shape. This enables easier and more efficient illumination of long premises such as corridors, see Fig. 1-4.
    8 and 9 additionally illustrate the shape of the light-reflecting partial areas 31-38 schematically and in a simplified manner. FIG. 8 shows the partial areas 31 and 33, which are designed as standard reflector areas, are designed with a parabolic shape and in particular are provided with a facet structure the reflector 30, cf. Figure 5A. In the middle section II-II of FIG. 9 normal to the section of FIG. 8, cf. 5A, the partial surfaces 32 and 34 formed with bulge-like protrusions toward the inner reflector region 40 are shown in a schematically simplified manner, as are the schematically indicated cutting lines (shown in dotted lines) of the partial surfaces 32 and 34 with the other two partial surfaces 31 and 33 in the region of the corners 39a. d of the reflector 30.
    Although the shape of the reflector 30 cannot be changed by a user, a number of different reflector shapes are preferably provided, by means of which the emission characteristic of the light segment can be modified in a suitable manner for different light effects. For some of the light segments, for example light segment 7 of FIG. 2, a design of the reflector without free-form surfaces can be considered, for example also a reflector with an inner region 40 which is round in cross section. For example, a user can choose 1 light segments during the initial configuration of the light 7, 8 from a variety of available light segments with different or the same outer contour and different reflector shape to meet the intended use. For example, different reflectors 30 could be provided for illuminating aisles of different widths.
    1-4 show several light segments 7 with the same square outer contour 9. However, the light segments 7 can have different reflector shapes, in other words, the shape of the reflector of the light segment 7 'differs from that of the reflector of the light segment 7 and this in turn differs from the shape of the reflector of the light segment 7 '. The same outer contour 9 is not only aesthetically interesting, but also makes the Kombi / 53 easier
    Nation of light segments 7 with different radiation characteristics, especially since the outer contour 9 does not vary. If the luminaire 1 is configured by selecting luminaire segments from a larger number of available luminaire segments, the essentially identical outer contour 9 can prove to be practical. If the outer contour 9 is identical, the outer contours 30u of the assigned reflectors 30 can also be the same, e.g. for all of the light segments 7 of FIGS. 1-4, even if the design of the partial surfaces 31-38 varies to provide different radiation characteristics.
    The above statements regarding the design of the reflector 30 can be applied analogously to the light segments 8 with the outer contour 10, in which case the reflector z. B. may have a round outer contour.
    The detachably inserted light segments 7 and 8 are each interchangeable, which means that changes to the lighting effects are still possible after the selection of the initial configuration and, if necessary, a damaged light segment can easily be replaced by a new one.
    The luminaire 1 as a whole can still be finely adjustable or adjustable in the assembled state of FIGS. 1-4, for example for fine adjustment of the overall alignment of the luminaire 1 and to compensate for assembly tolerances. This can be done by pivoting the lamp 1, for example, about the two axes A ', A, see FIG. 1, in particular within a limited angular range. However, it is alternatively possible to dispense with such adjustability of the lamp 1, which further simplifies the structure of the lamp 1.
    As mentioned, the lamp 1 according to the first embodiment is designed as a grid lamp. The luminaire base body 6 is dimensioned in such a way that it can be accommodated appropriately in a grid of the grid ceiling 3. This schematically illustrates FIG. 10, which also schematically shows profile elements 3a of the grid ceiling 3. The luminaire base body 6, which can in particular comprise a suitable housing, can also be equipped with suitable devices to hold the luminaire 1 in a grid of the grid ceiling 3 formed by the profile elements 3a.
    / 53
    A second exemplary embodiment sketched in FIG. 11 differs from the first exemplary embodiment only in that the luminaire 1 'is designed as a built-in luminaire instead of as a grid luminaire. For this purpose, the luminaire 1 'can have a luminaire base body 6' adapted to the installation situation, which in turn can be designed with a suitable housing. A ceiling 3 'of the room 2 can, for example, have a suitable recess for receiving the luminaire base body 6'. The ceiling 3 'in one example can also be a suspended false ceiling, which, however, does not form a grid ceiling in this example.
    A third exemplary embodiment, sketched in FIG. 12, differs from the first exemplary embodiment only in that the lamp 1 is designed in a suitable manner and in particular has a suitably designed lamp base body 6 in order to be used as a suspended lamp 1. 12, the luminaire base body 6 has an independent housing, which remains visible after the luminaire 1 has been hung up. In Fig. 12, the lamp 1 is suspended, for example, by ropes on a ceiling 3 of the room 2. However, the lamp 1 can instead be suspended from the ceiling 3 by other suitable means.
    FIG. 15 shows a schematically highly simplified illustration of a light segment 7 or 8 for the lights according to the exemplary embodiments described above, wherein a section of the light base body 6, 6 ′ or 6 is also shown schematically and in a simplified manner. The light segment 7, 8 has the optical component 25, the light source 49, for example in the form of the LED arrangement 50, an arrangement 100 of electrical and electronic components for supplying and controlling the light source 49, in particular having a converter, latching devices 110 for mechanical fastening and for holding the light segment 7, 8 in the light base body 6, 6 ', or 6 and electrical contacting devices 120, in particular for establishing an electrical connection with a power supply, for example at mains voltage, e.g. B. 230 V on. The luminaire base body 6, 6 ′ or 6 is in turn provided with latching devices 111 and electrical contacting devices 121 on the luminaire base body side. The locking devices 111 are set up with the locking devices 110 ras / 53
    29 to come into engagement in order to hold the light segment 7 or 8 on the light base body 6, 6 'or 6, while the electrical contacting devices 121 are designed to come into contact with the contacting devices 120 and to establish an electrically conductive connection, to supply the light segment 7, 8 with electrical current. For this purpose, electrical supply lines can be provided in the luminaire base body 6, 6 'or 6, which for the sake of clarity are not shown in detail in FIG. 15.
    The components of the arrangement 100, the light source 49 and the contacting means 120 could, for example, be arranged on a common circuit board or printed circuit board or instead be provided separately in a suitable housing.
    In further exemplary embodiments of the invention, instead of the reflector 30, as described for the above exemplary embodiments, a lens can be used as the optical component 25 in order to influence the radiation characteristic of the respective light segment 7, 8. A lens 130 and a lens 230, which can be used by way of example in corresponding modifications of the first to third exemplary embodiments to influence the radiation characteristic, are shown schematically in FIGS. 16 and 17, it being understood that the lens 130 and 230, respectively View of material and geometry to the desired light effect and the desired radiation characteristics of the light segment 7 or 8 can be adjusted.
    The lens 130 according to a fourth exemplary embodiment, see FIG. 16, has a plate-shaped section 131 on an end face 135, which corresponds to a visible side S and on which the lens 130 emits light in the luminaire 1 when in use, the outer contour of which Example of FIG. 16 also defines the outer contour 131u of the lens 130. In the example in FIG. 16, the outer contour 131u of the lens 130 is square, although it is conceivable to provide lenses with a round, for example circular, outer contour 131u in a modification of the example in FIG. 16. In the case of the use of lenses, the choice of the outer contour 131u can also depend on how the positions 7a, 8a are provided in the lamp base body 6 and which outer contour 9, 10 the respective / 53
    -30Light segment should have. 16 shows the lens 130 together with its indicated central axis AA.
    In order to influence the radiation characteristic, which is achieved using the lens 130, the lens 130 has a recess 132 in the center on the front side 135, which is provided for setting the radiation characteristic and thus serves as optics for controlling or influencing the radiation characteristic. The recess 132 is thus formed in the lens 130 of FIG. 16 as a function of the desired radiation characteristic of the light segment which is equipped with the lens 130.
    On a rear side 136 of the lens 130 opposite the plate-shaped section 131, the latter has a further recess 133, in which the light source 49, preferably an LED or LED arrangement, is arranged in the light segment 7 or 8 when the lens 130 is in use.
    Furthermore, the lens 130 on the back 136 has two fixing sections 134, which are designed, for example, like bolts or cones and are used to fix the lens 130, in particular on a circuit board. However, other types of fixing the lens 130 in the light segment 7, 8, in particular on a circuit board which also carries the LED or LED arrangement, are also conceivable.
    In a variant of the fourth exemplary embodiment, a lens 230, see FIG. 17, could be provided instead of the lens 130. The lens 230 of FIG. 17 differs from the lens 130 of FIG. 16 only in that the lens 230 on the front side 135 is not provided with a recess 132 for influencing the radiation characteristic. If the desired radiation characteristic of the light segment 7 or 8 does not make a recess 132 necessary, this can be omitted.
    According to the fourth exemplary embodiment described above and the variant of the same explained, the light segments 7 and the light segments 8 each have a lens 130 or 230 instead of the reflector 30. If necessary, the light segment 7, 8 is then suitably set up around the lens 130 or / 53
    -31230 to be able to be attached in a suitable manner instead of the reflector. Beyond that, however, the luminaire according to the fourth embodiment and its variant is configured as described above for the first embodiment, and the luminaires according to the fourth embodiment and its variant can also be modified as explained above for the second and third embodiments.
    A lamp 1001 'according to a fifth exemplary embodiment and a lamp 1001 according to a sixth exemplary embodiment are shown in FIGS. 18 and 19. The lamps 1001' and 1001 each represent modifications of the exemplary embodiments described above and their variants, so that apart from the differences explained below reference is made to the above statements.
    The lamp 1001 'is installed in the wall area in a room 1002. The room 1002 has a ceiling 1003, a floor 1005 and at least one first wall 1004a and a second wall 1004b ′ opposite this. The luminaire 1001 'is installed in the second wall 1004b', the luminaire 1001 'having a luminaire base body 1006' adapted to the installation situation in the wall 1004b '. In the exemplary embodiment in FIG. 18, the luminaire base body 1006 'is formed with a housing which is set up for installation in the wall 1004b'. The luminaire base body 1006 'is accommodated in a suitable recess in the wall 1004b' in FIG. 18 and held with the aid of holding means, not shown.
    In the sixth embodiment of FIG. 19, the lamp 1001 is also installed in the wall area. Again, the room 1002 has two walls 1004a and 1004b. The lamp 1001 is mounted on the surface of the wall 1004b. The luminaire 1001 is designed for this and in particular has a luminaire base body 1006 in order to be used as a surface-mounted or surface-mounted luminaire 1001. The luminaire base body 1006 of FIG. 19 has an independent housing which remains visible after the luminaire 1001 has been mounted on the wall 1004b.
    The generation of a light effect 1011 on the first wall 1004a is shown schematically in both FIG. 18 and FIG. 19. However, it is understood that / 53
    32 of the lamp 1001 'and the lamp 1001 each, analogously to the generation of light effects by the lamps 1, 1', 1, different light effects can be generated. 18, 19, light effects can be generated not only on the wall 1004a but also on the floor 1005 and / or on the ceiling 1003 by means of suitable light segments 7, 8. Please refer to the above explanations.
    In the light 1001 ', the light segments 7 and 8 in their inserted state thus, see FIG. 18, form an arrangement which extends in a plane E', the plane E 'in FIG. 18 in the mounted state of the light 1001' runs vertically and parallel to a plane in which the wall 1004b 'extends. In the case of a built-in lamp 1001 ', the level E' and the level of the wall 1004b 'can coincide. The plane E 'is spanned by two directions R1', R2 ', which in FIG. 18 run perpendicular to one another and parallel to the wall 1004b', or in the plane of the wall 1004b '. 19, the light segments 7 and 8 also form an arrangement which extends in a vertical plane (not shown in FIG. 19) parallel to the wall 1004b.
    In particular, it should be mentioned that the above statements relating to FIG. 15 can also be applied to the lights 1001 ′, 1001.
    The switching and / or control of the light output of the light segments 7, 8 described above, individually, combined in disjoint and / or overlapping sub-groups, or all together, can be carried out in a variant not shown of all of the exemplary embodiments described above by means of leading to the individual light segments, live cables and switches or dimmers. For this purpose, for example, subgroups to be switched can already be specified when installing the luminaire 1, 1 ', 1, 1001', 1001 and a suitable number of switches or dimmers can be provided for these subgroups. The electrical connection of the light segments 7, 8 with the switches or dimmers then determines whether and how the light segments 7, 8 can all be switched or controlled together or individually or in subgroups with regard to their light output.
    / 53
    In a further variant of the exemplary embodiments described above, however, the switching and / or control of the light output of the light segments 7, 8 takes place in a manner schematically outlined in FIG. 13 via a bus 70. Each of the light segments 7, 8 is connected to a power supply, for example connected, which is not shown in Fig. 13 in detail. The activation, deactivation or dimming of the light segments 7, 8 takes place in the variant of FIG. 13, for example, with the aid of addresses assigned to the light segments 7, 8 and / or a suitable protocol and in a suitable form control and / or transport via the bus 70 or switching instructions. The light segments 7, 8 can thus be addressed in a particularly flexible and variable manner. Alternatively, a control network can be used instead of the bus 70. Each of the light segments 7, 8, see FIG. 13, has a device 71 which makes it possible to receive control signals for switching and / or controlling the light output of the light segment 7 or 8 via the wire 70 via the wire. In this case, the device 71 comprises an interface for connection to the bus 70. Alternatively, the interface can be designed for connection to a wired network.
    In a further, preferred variant of the exemplary embodiments described above, the control and / or switching of the light output of the individual light segments 7, 8 is not wired, but wireless, which avoids laying cables. This is outlined schematically in FIG. 14. Each of the light segments 7 and 8 has a communication device 72, which enables reception of control signals for switching and / or controlling the light output in a wireless way. In particular, the communication device 72 comprises an interface for communication via a wireless protocol.
    It should be mentioned that, in addition to the devices 71 or 72, each of the light segments 7, 8 can also have a computing device for processing the control signals and a driver component which enables the light output emitted to be varied in accordance with the control signals.
    / 53
    The devices 71 and 72 as well as the computing device and the driver component can be part of the arrangement 100 schematically indicated in FIG. 15.
    Furthermore, it should be mentioned that in the exemplary embodiments described above, the light segments 7, 8 and the light base body 6, 6 ', 6, 1006' and 1006 can have contacting means 120, 121, see FIG. 15, which are not only suitable for one To make electrical contact of the light segments 7, 8 with a power supply, but, if a wired control is to be possible, additionally make it possible, for example, to make contact with a data line, for example for the bus 70. Alternatively, it would be conceivable to provide separate contacting means for the data line.
    Although the present 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.
    In particular, the invention is not limited to a lamp with the number and combination of lamp segments specified in the exemplary embodiments. More or fewer light segments could be provided, all of which can have, for example, a rectangular or square outer contour. Many numbers and combinations of light segments are conceivable.
