    Description: The present invention relates to a luminaire which has a lighting unit which is held by a scaffold structure and which has a light emission opening provided for light emission. The lighting unit is particularly intended to emit light directed via the light emission opening.
    Depending on the task in lighting technology, light is emitted in different ways. If, for example, it is desired that there are optimal lighting conditions for performing work or reading, this often requires a relatively high brightness in the area to be illuminated. Furthermore, the light should also be emitted in such a way that glare effects and / or disruptive reflections on screen surfaces or the like are avoided. Appropriate standards also exist for such directional lighting, which is used, for example, to illuminate workplaces.
    On the other hand, a rather large-area lighting is often desired, in which the light is emitted rather diffusely, since this is optically more appealing to an observer. In this case, however, the high luminance levels that would be optimal for working or reading cannot usually be achieved in an area to be illuminated.
    [0004] If light is emitted in a directed manner, LEDs are now often used as light sources. In terms of their dimensions, these are very small light sources, so that the associated further optical means generally also have rather small dimensions in the case of directional light emission. It is therefore often desirable to integrate such means for directional light emission into a larger luminaire, through which light may then additionally be emitted over a large area.
    The present invention is accordingly based on the task to provide a way to integrate means for directional lighting in a lamp, which means for directional light output are harmoniously integrated into the external appearance of the lamp.
    The object is achieved by a lamp which has the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.
    The solution according to the invention is based on the idea of first providing the lamp with a base, a so-called scaffold structure, on which at least one lighting unit is held, which has a light emission opening provided for directional light emission. The light emission opening is now harmoniously integrated into the luminaire housing, in that at least a partial area of a cover of the luminaire is formed by a covering, which is formed from a flexible material and is fixed to the frame structure at its edge region, the covering material additionally also on the outer circumference of the light emission opening Lighting unit is fixed.
    According to the invention, therefore, a lamp with a scaffold structure and a lighting unit held by the scaffold structure is proposed, which has a light emission opening provided for light emission, at least one partial area surrounding the light emission opening of the cover of the lamp being formed by a covering made of a flexible material is formed and fixed to the framework structure at its edge area, and the covering material is additionally fixed to the outer circumference of the light emission opening of the lighting unit.
    Characterized in that the cover according to the invention is formed by a flexible material which is attached to the corresponding components of the lamp, this can adapt in a flexible manner to the corresponding structures of the lamp. This has the effect that the light emission opening fits harmoniously into the exterior of the lamp and, in particular, there are no projections or edges that adversely affect the appearance of the lamp. Instead, the light emission opening used for the directed light emission harmoniously continues the shape of the surface of the housing.
    This advantageous effect is achieved in particular when, according to the present invention, the light emission opening of the lighting unit projects beyond a plane defined by the scaffold structure. This results in a complex three-dimensional surface design of the exterior of the lamp, which, however, can be achieved in a relatively simple manner. In particular, it is not necessary to use extremely complex and therefore difficult to manufacture surface parts for the luminaire housing. Instead, a lamp is created that has a completely new, extremely appealing shape.
    It is particularly preferably provided that the covering material has an opening which corresponds to the light emission opening of the lighting unit. In this case, the covering material is only fixed to the edge area of the light emission opening, but otherwise leaves it free.
    According to a particularly preferred embodiment of the invention, it can further be provided that light is also emitted via the area of the luminaire surrounding the light exit opening, but now the flat and possible diffuse light emission already mentioned is present. For this purpose it can be provided that the covering material is at least partially translucent, the luminaire then having further illuminants in order to emit light over the covering material over a wide area.
    CH 712 771 A2 [0013] According to a particularly preferred exemplary embodiment, it is provided here that the further illuminants are likewise part of the lighting unit. In this case, only one lighting unit, which is present as a structural unit, can be used here, which is fastened in its entirety to the framework structure and is then responsible for the two different types of light emission.
    It is provided according to a particularly preferred embodiment that the scaffold structure has a plate-shaped light-guiding element which is designed to emit light via at least one flat side and is spanned on this flat side by the flexible material of the cover, the further illuminants being arranged in this way that light which is emitted by these further illuminants initially enters the light-guiding element. With the help of this light-guiding element, the large-area light emission can be optimized again, since this allows a better distribution of the light before it is then emitted to the outside through the flexible, translucent covers of the lamp. The light-guiding element can have an opening or recess in which the lighting unit is arranged, the further illuminants then being distributed around the circumference of fastening elements of the lighting unit and arranged facing an edge surface of the recesses in the light-guiding element.
    The inventive design of the outside of the lamp can only be provided in a partial area of the lamp surface. However, it is particularly preferably provided that the lamp body as a whole is designed in the manner according to the invention. In particular, it can be provided that the lighting unit protrudes on both sides beyond the light-guiding element mentioned above and that both sides of the light-guiding element are covered with the flexible material. Of course, the light-guiding element is then also designed in such a way that a two-dimensional light emission is achieved on both sides, whereby it would also be conceivable, if necessary, to cover the rear side of the lamp opposite the light exit opening with an opaque flexible material, so that there is no light emission, the shape However, the lamp corresponds to the design of the front side responsible for the light emission.
    The cover used according to the invention preferably consists of a so-called bidirectionally flexible textile material. The scaffold structure can have an outer frame to which the covering material is attached. For this purpose, the frame can have at least one outward-pointing groove in which the covering material is suspended with a piping provided on the covering material.
    As already mentioned, the lighting unit is used in particular for directional direct lighting. It is therefore preferably provided that it has a spotlight, the light exit opening of which then forms the light exit opening of the lighting unit. It can particularly preferably be provided that the radiator is adjustable, in particular gimbal-mounted. In this case, there is then the possibility of aligning the spotlight accordingly and of directing the light in a desired preferred direction. The fact that the covering material, which is connected to the light exit opening of the spotlight, is flexible, ensures that the shape of the luminaire then adapts automatically according to the orientation of the spotlight, and nevertheless the harmonious integration of the light emission opening into the lamp cover according to the invention is achieved.
    [0018] Of course, according to the invention, a plurality of lighting units can be provided. With regard to the implementation of the luminaire according to the invention, there is great freedom.
    The invention will be explained in more detail with reference to the accompanying drawing. Show it:

    Fig. 1 shows a lamp generally provided with the reference numeral 1, in which the inventive concept is used. In the exemplary embodiment shown, the luminaire 1 is designed as a pendant luminaire, since — as can be seen clearly from the description below — the advantages of the solution according to the invention are particularly effective. Despite everything, it would also be conceivable to use the present invention in the form of other types of lights
    CH 712 771 A2, for example as a surface-mounted or recessed ceiling light or as a floor or table lamp. In these cases, the scaffold structure described in more detail below may only be spanned with the cover on one side.
    The actual luminaire body 5 is suspended with the aid of a narrow, elongated ceiling-mounted housing 3, which is mounted directly on a support element, for example on the ceiling of a room or the like. Such a ceiling-mounted housing 3 could, however, possibly also be dispensed with. In the case of the pendant lamp shown, the ceiling-mounted housing 3 also serves to accommodate operating devices for the power supply, the suspension of the lamp body 5 then taking place via ropes 4 which extend downward from the two end regions of the ceiling-mounted housing 3. As will be described in more detail below, these ropes 4 serve not only for the mechanical mounting of the lamp body 5 but also for the power supply to the units arranged in the lamp body 5, which are responsible for emitting light.
    The special feature of the lamp 1 according to the invention is the design or shape of the lamp body 5 and the manner in which the light is emitted.
    The shape of the lamp body 5 is in this case first of all characterized by the fact that, in the present case, a rectangular, elongated basic structure is formed by a framework structure described in more detail below, which forms a horizontal - central plane E of the lamp body 5 here. On both sides of this level E, the framework structure is spanned by a cover 10, which is fixed on the one hand with its edge region to the frame of the framework structure, but on the other hand is spanned or fixed on both sides of shaping elements that protrude beyond the plane E. Since the material of the cover 10 is flexible, it follows in a curved manner the paths predetermined by the framework structure or the frame of the framework structure and by the shaping elements, so that the recognizable three-dimensional design of the exterior of the lamp body 5 ultimately results. In the following it will be explained in detail how this special, extremely appealing design of the surface can be achieved.
    Another special feature of the lamp body 5 is namely the way in which light is emitted. For example, illuminants are initially provided, with the aid of which light can be emitted over a large area and preferably diffusely via the translucent cover 10. In other words, the flexible covering material is designed to be translucent, in which case illuminants, which are described in more detail below, are then arranged in the interior of the lamp body 5 enclosed by both coverings, with the aid of which light is emitted diffusely as far as possible over the entire cover 10.
    In the present case, the diffuse light is emitted via the cover 10 both towards the bottom and towards the top, since in both cases the identical translucent material is used for the covering. However, this is also not absolutely necessary and it can be provided that the two materials which are used for covering the underside and for covering the upper side differ from one another and e.g. light is only emitted in one direction. Furthermore, it would also be conceivable in certain cases that the material for realizing the lamp cover 10 is completely opaque and, accordingly, no planar light emission is provided.
    The luminaire 1 shown has moreover in addition further means by means of which light can be directed and preferably emitted bundled in a certain direction. These are lighting units which are also described in more detail below, which in turn are each fastened to the framework structure already mentioned and have a light exit opening for directional light emission. In the present case, these lighting units are arranged in such a way that a directed light emission is provided towards the underside, although it would of course also be conceivable to arrange or orient at least some lighting units in such a way that light is emitted directed towards the upper side, for example in order to specifically target a specific area to lighten the ceiling.
    The covering material forming the cover is now designed in such a way that it extends from the frame, that is, the circumference of the scaffolding structure, to these light exit openings of the lighting units, but does not cover them. Ie, light outlet openings of the lighting units preferably also form light outlet openings 11 of the lamp cover 10 at the same time, and the covering material does not influence the light output realized by the lighting units, although it would also be conceivable that the covering material would cover the light outlet openings of the lighting units and at least in these areas is that it has little or no influence on the directional light output.
    In the illustrated embodiment, the lighting units described in more detail below also simultaneously represent the shaping elements already mentioned above, with the aid of which the three-dimensional design of the surface of the lamp body 5 is achieved. As an alternative or in addition to this, other shaping elements could also be provided on the scaffold structure, which do not emit light, but are specifically used to influence the shape of the lamp body 5 due to the effect already described above by correspondingly protruding from the plane E of the scaffold structure.
    CH 712 771 A2 The components of the lamp 1 according to the invention which are located inside the lamp body 5 will now be explained in more detail below. As already mentioned above, it is assumed here that the scaffold structure forms an elongated, rectangular basic shape, to which the further units, in particular the lighting units for direct light emission and, if appropriate, additionally or alternatively, shaping elements provided without a lighting function are then attached. However, it should be pointed out that the concept according to the invention can be implemented in a significantly more versatile manner and, of course, the number of lighting units used for the directional lighting or the number of shaping elements can also be freely selected. The basic shape of the luminaire body 5 predetermined by the framework structure does not have to be rectangular or square, but could have any shape. In particular, a polygonal or generally a polygonal shape or an oval or elliptical shape, in particular a circular shape, would be conceivable.
    2 and 3 show first two views of the lamp 1 in a state in which the two covers 10 and coverings described above have been removed. In particular, the perspective view of FIG. 3 shows the frame-like framework structure 20 by which the circumferential shape of the lamp body 5 is determined. It can also be seen that a total of six lighting units 50 are used in the case shown. As already mentioned, these lighting units 50 serve, in particular, for direct or directed light emission to the underside, but at the same time they also have other means for generating light, with the aid of which light is emitted across the lamp covers 10.
    The central element of the scaffold structure 20 is a plate-shaped light guide 25 which is surrounded at its edge by frame parts 30 which are mitred in the corner areas and are joined to form a frame 21 surrounding the light guide 25. The frame structure 20 is suspended from the ropes 4 via this frame 21, which will be described later. Furthermore, the frame parts 30 also serve to hang the covering material.
    Since the plate-shaped light guide 25 should be as light and thin as possible and accordingly has a thickness of only a few millimeters in the present case, its stability is rather low even in cooperation with the frame 21. For additional stabilization of the framework structure 20, a reinforcement 22 extending centrally in the longitudinal direction on the upper side of the light guide 25 is therefore provided. At its end regions - as can be seen in FIG. 3 - it is coupled to the circumferential suspension cables 4. Since the reinforcement 22 is screwed to the light guide plate 25, this results in an overall sufficiently stiff or stable construction, in which an undesired bending of the frame structure 20 is prevented despite the not inconsiderable length of the lamp body 5. The reinforcement 22 also has the advantage that it can be used to accommodate components for supplying power to the lighting units 50.
    The design and mounting of the lighting units 50 will now be explained in more detail below. On the one hand, these are responsible for the direct or directed illumination towards the underside, on the other hand, however, they also have means for generating light, by means of which the above-mentioned light emission via the lamp cover 10 takes place. Strictly speaking, these further means for generating light are designed such that they couple light into the light guide 25. Within this light guide 25, the light is then distributed in a known manner as evenly as possible by multiple reflections, then coupled out flat across the top and bottom of the light guide 25 and finally emitted via the cover 10. As already mentioned, depending on the type of light output desired, it can be provided that light is emitted only via one of the two flat sides of the light guide plate 25. The light is decoupled from the light guide plate 25 in a known manner in that its surface (s) is or are provided with special decoupling structures which deflect the incident light such that it is no longer totally internally reflected, but instead via one of the flat sides can leave the light guide plate 25.
    Views of an individual lighting unit in the state not mounted on the light guide 25 are shown in FIGS. 7a to 7e. The actual light output for direct lighting takes place by means of a cylindrical spotlight 60, which has a circular light exit opening 62 on the front or underside of its cylindrical housing 61, via which the light output takes place. In the illustrated embodiment, according to the sectional view of FIG. 5 or 6, an LED circuit board 64 arranged within the spotlight housing 61 is used with an associated LED 65 or an LED cluster as a light source, this LED 65 being arranged upstream of a lens 66, with the aid of which the LED light collimates, that is, it is formed into an approximately parallel beam, which is then emitted via the light exit opening 62. The lens is a so-called TIR lens, which has already been known for a long time, although obviously, as an alternative to the illustrated embodiment of the radiator 60, other optical systems could also be used, with the aid of which direct, directed light emission can be achieved.
    Each lighting unit 50 thus has a radiator 60 which - as can be seen, for example, from the sectional views in FIGS. 4 to 6 - is positioned such that it is approximately in the center of the plane of the light guide plate 25 and thus plane E of the framework structure 20 is arranged. That is, the radiator 60 projects beyond the horizontal plane E of the framework structure 20 both towards the bottom and towards the top. The light guide plate 25 in this case has a circular receptacle - or assembly opening - in which a lighting unit 60 is then mounted.
    CH 712 771 A2 The cylindrical housing 61 of the radiator 60 is gimbal-suspended in the preferred exemplary embodiment shown, so that the radiator 60 can be pivoted freely and thus align the directed light emission. However, a rigid holder or a holder that only allows pivoting about a single axis would also be conceivable for at least some of the radiators 60.
    The attachment of the radiator 60 together with the means for the gimbal 70 takes place here via several ring-like mounting elements, which can be seen in particular in the sectional view of FIG. 6.
    First, a first, annular angled fastening part 75 is provided, which is designed such that it rests with a lower, horizontal leg 76 on the underside of the light guide plate 25. From this horizontal leg 76 extends on its inner circumference a second vertical leg 77, which initially has two mutually opposite openings 78, into which suspension elements 71 of the gimbal bracket 70 engage. On the other hand, LED boards 90 which are uniformly distributed over the circumference and are directed outward are provided on the circumferential wall of the vertical web 77 (see FIGS. 7a and 7c).
    For further assembly of the lighting unit 50, an upper mounting ring 80 is provided, which can be connected to the angled fastening part 75 by means of a plurality of screws 81. Furthermore, a further spacer ring 85 is provided below the upper mounting ring 80 and is positioned between the underside of the ring 80 and the top of the light guide 25.
    The lighting unit is then assembled by first attaching the angled fastening part 75 with the gimbal 70 attached to it and the radiator 60 from the underside to the mounting opening of the light guide 25. In this state, the spacer ring 85 is then placed from the top and finally the second mounting ring 80 is connected to the lower angled fastening part 75 with the aid of the screws 81. This results in the entire unit being clamped on the light guide 25 and the lighting unit 50 is accordingly fixed in the desired position on the light guide 25. The mounting opening of the light guide 25 and the corresponding fastening parts for the lighting unit 50 do not necessarily have to be circular, but can also have a different shape, for example a square shape.
    In the assembled position of the lighting unit, the LED boards 90 are positioned and aligned in such a way that they lie opposite the edge region of the mounting opening of the light guide 25, that is to say the inner peripheral surface 26. When these LEDs 91 are activated, the light is coupled into the light guide 25 via the edge region of the mounting opening. It is further advantageously provided that - as can again be seen in FIG. 6 - those areas of the angled fastening part 75 and the spacer ring 85 between which the light guide 25 is clamped are provided with a ring-like reflecting element 79 or 86. This is preferably a highly reflective material, on the one hand optimizing the coupling of light, on the other hand mixing the light and thus making the coupling more uniform over the entire circumference in the light guide 25 is improved. This measure also contributes to the fact that the flat light guide 25 is illuminated uniformly and ultimately the luminaire cover 10 then appears in a uniform brightness.
    A uniform light emission via the lamp cover 10 is also optimized in that - as can be seen in particular from FIG. 3 - the lighting units 60 are positioned as evenly as possible in the plane of the light guide plate 25. At the same time, however, this positioning of the lighting units 50 also allows them to be supplied with electricity in a simple manner, as will be explained in more detail below.
    To suspend the luminaire body 5 and power supply of the lamps, it is provided that the cables 4 led downwards from the ceiling-mounted housing 3 are passed through the frame parts 30 at special openings 34. A strain relief element 38, which can be seen in FIGS. 8 and 9, is additionally inserted into the frame parts 30 in the area of the ropes 4 and is looped over by the rope 4, so that a strain relief preferred for secure suspension is achieved here.
    The ropes 4 then extend above the light guide 25 to the central reinforcement 22 and are here electrically coupled to further lines and units used for power supply, which lead to the lighting units 50 along the reinforcement. It can be provided that the central reinforcement 22 is U-shaped and thereby contains an elongated receiving space for further power supply units for the power supply of the lamps. These can be small circuit boards or electronic components which finally convert the supply voltage supplied via the suspension cables 4 into a suitable voltage for the operation of the LEDs 65 of the radiators 60 and the LEDs 91 responsible for coupling the light into the light guide 25. For example, it can be provided that an operating device arranged in the ceiling-mounted housing 3 first converts the general mains supply voltage into a low-voltage supply voltage, which is supplied to the lamp body 5 via the suspension cables 4. The actual power supply of the lighting units 50 then takes place by means of the further electronic components which are positioned in the central reinforcement 22.
    It can preferably be provided that the directional light output can be set independently of the flat and possibly diffuse light output realized via the cover 10. A corresponding additional transmission of control information may then be required for this, which may then require the use of additional lines for signal transmission or for a separate power supply for the corresponding lamps.
    CH 712 771 A2
    Of course, in addition to this, it could also be provided that the illuminants can be adjusted in their intensity and / or color or color temperature.
    Of course, however, a different positioning for the means for power supply can also be realized. In the case of the pendant lamp, it would also be conceivable to dispense with the ceiling-mounted housing 5 and to arrange suitable operating devices which convert the mains supply voltage into a voltage suitable for LED operation directly in the receiving space of the central reinforcement 22.
    After mounting the lighting units 50 on the light guide plate 25, the resulting arrangement is then covered with the flexible material that forms the cover 10 of the lamp body 5. A so-called bidirectionally flexible textile material is preferably used for this, which is therefore stretchable in two mutually perpendicular directions of the material plane. As already mentioned, the material can be made translucent in particular if diffuse brightening of the lamp body 5 is desired. In this regard, however, there are no general restrictions and it would also be conceivable to use a material which is designed in a special way in order to give the surface of the lamp body 5 a special appearance. A patterned material or even an opaque material could also be used for this, different materials with different optical properties possibly being used for the top of the lamp body 5 and the bottom.
    It is essential, however, that the material on the one hand is braced over its circumference with the scaffold structure 20, on the other hand it extends to the lighting units 50 and is supported or also fixed there, whereby the outer cover 10 of the lamp body 5 ultimately takes the form recognizable in Fig. 1.
    The covering material 10 is braced with the frame 30 in that the frame parts — as can be seen in FIG. 8 or 9, for example — are designed in such a way that two longitudinal grooves 31 and 32 open to the outside are formed, which serve to hang the edge area of the covering material 10. Strictly speaking, according to the representation of FIG. 9, the covering has a so-called welt 12 on its edge region, which is inserted into the outwardly directed groove 32. The covering material wraps around the outwardly directed lower edge of the frame part 30, so that it is firmly attached here. Since the covering material 10 is preferably suspended in the frame parts 30 over its entire circumference in the manner described above, it is accordingly under tension, so that it is adequately fixed to the frame parts 30 by this measure. After both the upper and the lower cover 10 have been attached to the frame in this way, a T-shaped cover 35 is then placed on the frame parts 30, which engages with a central web 36 in a corresponding receiving opening of the frame part 30 and here is jammed. This frame 35 primarily closes the frame all the way around, the frame 35 is not absolutely necessary for holding the covering material.
    The covering material clamped in this way with the frame 21 then covers both the top and the bottom of the framework structure 20, which is formed in particular by the flat light guide 25 and the frame 21 and the reinforcement 22. On the other hand, the covering or cover 10 is, however, also fixed to the lighting units 50, strictly speaking on the front or rear sides of the radiators 60, so that the lighting units 50 protruding beyond the plane of the light guide plate 25 achieve a special curved, three-dimensional shape of the cover becomes.
    The cover 10 has the light exit opening 62 of the radiator 60 and the circular rear of the radiator 60 corresponding recesses or openings. The cover 10 is fastened to the spotlight 60 in the region of the light exit opening 62 with the aid of two clamping rings 67 and 68, which engage in one another in such a way that they can be clamped or locked together, but at the same time can also be fastened to the spotlight housing 61. The edge area of the covering material is first inserted into the inner area of the outer ring 67. The second clamping ring 68 is then inserted from the opposite side, so that it engages with the outer ring 67 and clamps the textile material between them. The arrangement consisting of the two rings 67 and 68 with the covering material jammed therein is then placed on the front end region of the cylindrical radiator housing 61. As a result, the covering material is flush with the light exit opening 62 of the radiator 60.
    On the other hand, the covering material is fixed on the back of the lamp by the fact that it in turn has an opening, the size of which is dimensioned somewhat smaller than the outer circumference of the rear lamp housing 61. This has a removable cover 69, which is attached with the aid of a screw 69a the radiator housing 61 can be fixed. The covering material is thus positioned in such a way that it lies at least in the edge area on the back of the radiator housing 61. The rear cover 69 is then screwed on, so that the covering material is also fixed to the radiator 60 here. For reasons of clarity, the anchoring of the covering material on the frame 21 on the one hand and the radiator 60 on the other hand is only partially shown in FIGS. 5 and 9.
    By means of the measures described above, the covering material is clamped on the one hand between the surrounding frame 21 and on the other hand on the lighting units 50, in such a way that due to the Flexi7
    CH 712 771 A2 bility of the material results in a curved surface design of the cover 10, which follows the positioning of the lighting units 50. This results in a particularly appealing design of the luminaire housing, which gives the luminaire 1 a particularly interesting appearance, which may be further emphasized by the fact that the surface of the luminaire housing can also emit light or appear luminous with the aid of the LEDs 91.
    The previously described effect of the design of the surface shape can be further enhanced by the fact that the emitters 60 are adjustable due to the gimbal suspension mentioned, in particular can thus be aligned in the desired manner in order to emit light in a very specifically selected angular range. Due to the flexibility of the covering material, this can follow an adjustment of the emitters 60, so that despite the different alignment of the emitters 60, a closed luminaire cover is achieved, aside from the light emission openings 11. The gimbal for the radiators 60 is selected such that they maintain the set orientation despite the tension of the cover 10. A certain friction of the gimbal suspension elements is therefore required for this, or corresponding latching means are provided, which lock the radiators 60 accordingly in the set orientation.
    The concept of the special design of the surface or shape of the lamp body 5 described above is not necessarily limited to using adjustable lighting units 50 for this purpose. Instead, other, non-light-emitting shaping elements could also be used, which through appropriate positioning and connection to the covering material ensure that the lamp cover is given a special design. In the event that these shaping elements are designed to be adjustable, the end user can in turn flexibly influence the shape of the lamp.
    Ultimately, with the help of the solution according to the invention, a possibility is created to emit light in an appealing manner and to perform a wide variety of lighting tasks. At the same time, the external appearance of a lamp can be designed in a particularly positive manner by the measures according to the invention.
