Description

The invention relates to a straight and longitudinally extending luminaire for a light strip according to the preamble of claim 1.

Luminaires for a light strip are already known from the prior art. The light band usually comprises several straight luminaires that are mounted in a row on a wall or on a ceiling. The respective luminaire usually comprises a support profile with a current guide rail, on which a device carrier with a light source plate is fixed. The light source plate with several light sources is supplied with power via the power supply rail and controlled by a control device in the support profile. The device carrier is usually closed with an optics cover through which the light generated by the light sources is scattered. Many components have to be assembled in the luminaire, which makes assembly more difficult and increases manufacturing costs. In DE 10 2013 216 275 A1 a generic lamp with a support profile, a device carrier and an optical cover is disclosed. Here the equipment rack is attached to the support profile by means of a clamp and the lens cover is attached to the equipment rack by means of a tongue and groove connection.

The object of the invention is to provide an improved or at least alternative embodiment for the luminaire of the generic type in which the disadvantages described are overcome.

According to the invention, this object is achieved by the subject matter of independent claim 1. Advantageous embodiments are the subject of the dependent claims.

The present invention is based on the general idea of assembling individual components in a luminaire and thereby simplifying the assembly of the luminaire. The straight and longitudinally extending lamp is intended for a light band and has an elongated U-shaped support profile and an elongated U-shaped device carrier which is positively fixed to the support profile. The device carrier closes the support profile transversely to the longitudinal direction at least in some areas with a profile locking base and a profile interior is thereby formed in the support profile. The luminaire also has at least one elongated optics cover that is attached to the device carrier. The at least one optics cover closes the device carrier transversely to the longitudinal direction and a carrier interior is thereby formed in the device carrier. The lamp also has at least one elongated light support plate with several light sources, which is fixed in the carrier interior of the device carrier. The lamp has at least two elongated V-shaped retaining clips, each with a first support wing and a second support wing, which are each connected to one another by a support edge. According to the invention, the respective retaining clip is supported in the carrier interior with the first support wing on the luminous support plate, with the second support wing on the at least one optics cover and with the support edge on an elongated support contour of the device carrier. The luminous support plate and the at least one optics cover are also fixed in the carrier interior towards the support profile on the device carrier so that the holding effect of the retaining clip can be reinforced by the weight of the luminous support plate and the weight of the optics cover.

When the lamp is properly aligned for operation, the holding effect of the retaining clip in the lamp according to the invention can be reinforced by the weight of the light support plate and by the weight of the optics cover. In particular, the weight force is then from the luminous support plate and from the optics cover directed towards the elongated support contour of the device carrier, so that the retaining clip is reinforced on the support contour as a result. In particular, the retaining clip according to the invention can thereby be used for secure, sustainable fastening of the luminous support plate and the optical cover in the interior of the support to care. Furthermore, dismantling of the optics cover can be made more difficult because when the optics cover is detached from the device carrier, the retaining clip is reinforced on the support contour and detachment of the optics cover can be prevented.
Appropriately, the support profile can have a current guide rail with several electrical conductors, which can supply the several light sources on the luminous support plate with power. For this purpose, an electrical connection element can be provided on the luminous support plate, by means of which the multiple light sources on the luminous support plate can be connected to the power supply rail. For this purpose, the electrical connection element can engage in the power supply rail and in this way electrically connect the multiple light sources to at least one of the conductors of the power supply rail. The connection element can also be electrically connected to a control device that can control the multiple light sources individually or in groups. Appropriately, the plurality of light sources are arranged on a front side of the luminous support plate, which is arranged facing the optics cover in the carrier interior. The electrical connection element can then appropriately be fixed on a rear side of the luminous support plate facing away from the front side and thereby facing the profile interior.

In the lamp according to the invention, the device carrier is closed with at least one optical cover. The at least one optical cover is expediently designed to be at least partially and at least partially light-transparent. The luminaire can, for example, have a single lens cover that closes the device carrier transversely to the longitudinal direction. Alternatively, several - and preferably two - optical covers can also be provided, which are arranged next to one another transversely to the longitudinal direction and close the device carrier transversely to the longitudinal direction. The carrier interior can be divided in the longitudinal direction by at least one intermediate flange of the device carrier and the respective optics cover can then be fixed on one side between a flange of the device carrier and the respective intermediate flange adjacent to the flange, or alternatively between two adjacent intermediate flanges. The respective intermediate flange can expediently have the inner contour of the facing flange on both sides, so that the optics cover can be fixed to it. Correspondingly, the distance between the flanges in an equipment rack without an intermediate flange and the distance between the flanges and the respective intermediate flange and the intermediate flanges from one another in an equipment rack with the respective intermediate flange can be the same. Advantageously, the optics cover, the luminous support plate as well as further components arranged in the device carrier can then remain configured in the same way in a device carrier with and without the at least one intermediate flange.

By means of the respective retaining clips, the luminous support plate and the optics cover are advantageously fixed together in the interior of the support and additional fastening means are dispensed with. This allows both the production costs to be reduced and the assembly of the lamp to be simplified. The retaining clip can advantageously also ensure that the luminous support plate and the optics cover are securely and sustainably fastened in the interior of the support. In addition, the retaining clip according to the invention makes dismantling of the optics cover more difficult, so that the risk of injury to a person who is not responsible is reduced.

Advantageously, it can be provided that the respective retaining clip presses the luminous support plate in the carrier interior onto the device carrier towards the carrier profile through the first support wing. As a result, the light support plate rests against the device carrier and the heat generated in the light support plate can be dissipated to the device carrier. In addition, the respective retaining clip presses the at least one optics cover into the through the second support wing Carrier interior to the light support plate to the support profile. In this way, the luminous support plate is pressed against the device carrier and the optics cover on the luminous support plate is pressed towards the support profile. The optics cover thereby encloses the light sources fixed on the light support plate transversely to the longitudinal direction and the light sources on the light support plate can thereby be better protected from contamination.

Furthermore, it can advantageously be provided that the first support wing of the respective retaining clip has at least one first beveled bevel area and at least one second beveled bevel area. The respective folding areas are folded transversely to the longitudinal direction and extend in the longitudinal direction. The at least one first folded area can fix the luminous support plate towards the supporting profile on the device carrier and the at least one second folded zone can fix the luminous supporting plate parallel to the supporting profile and laterally transversely to the longitudinal direction. The at least one first folding area and the at least one second folding area both act transversely to the longitudinal direction, so that the luminous support plate is fixed on the device carrier such that it can be displaced in the longitudinal direction. In particular, thermal expansion of the luminous support plate in and across the longitudinal direction can thereby be compensated for and distortion of the luminous support plate during operation of the lamp can advantageously be prevented.

In the interior of the support, a retaining clip can be arranged on both sides of the light support plate, so that the light support plate lies against the device carrier and is fixed transversely to the longitudinal direction through the folding areas of the first support wing of the respective retaining clips. The respective second folded areas of the first support wing of the respective retaining clips do not prevent any thermal expansion of the luminous support plate transversely to the longitudinal direction, so that a distortion of the light support plate during operation of the lamp can advantageously be prevented.

Advantageously, it can also be provided that the second support wing of the respective retaining clip has at least one third beveled bevel region which is beveled transversely to the longitudinal direction and extends in the longitudinal direction. The third folding area defines the at least one optical cover towards the luminous support plate. The third folded area of the second support wing of the respective retaining clip can bear against a support surface of the optics cover that extends in the longitudinal direction in order to enable a large-area contact of the second support wing with the optics cover.

In order to fix the respective retaining clip so that it cannot be displaced in the device carrier in the longitudinal direction, a plurality of tips can be integrally formed on the supporting edge of the respective retaining clip. The tips fix the retaining clip in the longitudinal direction on the respective support contour of the device carrier.

In an advantageous further development of the lamp according to the invention it is provided that a seal extending in the longitudinal direction is arranged between the at least one optics cover and the device carrier. The seal is supported on one side on the device carrier and on the other side on the at least one optical system cover and fixes the at least one optical system cover to the support profile in the carrier interior.

Advantageously, the seal can press the luminous support plate onto the device carrier towards the support profile. In particular, this allows the optics cover to be securely attached to the device carrier and an undesired detachment of the optics cover from the device carrier can be prevented. The seal can be elastic, for example, to prevent deformation of the optics cover or the To compensate device carrier due to thermal expansion during operation of the luminaire. The seal can advantageously be injection-molded onto the at least one optics cover in order to reduce the manufacturing costs.

In an advantageous development of the lamp according to the invention, it is provided that the device carrier has a light support base which is arranged parallel to and spaced apart from the profile locking base and extends in the longitudinal direction. The light support base divides the support interior into a light interior with the at least one light support plate and a heat insulating space which is arranged in the longitudinal direction between the profile interior and the light interior. The luminous support plate with the multiple light sources is then arranged in the luminous interior adjacent to the luminous support base and can be fixed - for example pressed on - to the latter by the respective retaining clips.

The heat insulating space is arranged between the light interior and the profile interior and isolates the profile interior and the light interior from one another. In this way, in particular, the direct heat transfer between the luminous support plate with the multiple light sources and electrical or electronic components in the profile interior - such as a control device, for example - can be minimized. In this way, the heat generated in the luminaire can preferably be dissipated to the outside and the functionality of the luminaire can advantageously be retained.

Advantageously, it can be provided that the profile locking base is integrally formed by at least one projection facing the support profile on the luminous support base of the device carrier, the projection having a T-shaped cross section transversely to the longitudinal direction and extending in the longitudinal direction. Alternatively, the profile locking base can be attached by means of two lateral projections be integrally formed with the light support base of the device carrier, the projections facing one another and extending in the longitudinal direction. Both the support profile and electrical or electronic components in the profile interior - such as a control device - can be supported on the respective projections. The respective projection expediently extends in the longitudinal direction over an entire length of the device carrier, so that the profile interior and the light interior are separated from one another in a heat-insulating manner over an entire length of the lamp.

In a further development of the device carrier, it is advantageously provided that the light support base has at least one guide formation for centering the light support plate. The guide formation is directed into the light interior and extends in the longitudinal direction. The guide formation facilitates a centered fixing of the light support plate with the multiple light sources in the light interior, whereby the assembly of the light is simplified.

The equipment carrier can advantageously be clamped in the support profile on both sides in the longitudinal direction. In particular, the assembly and disassembly of the device carrier on the support profile can be simplified as a result. For example, flanges of the device carrier can be arranged in the profile interior and clamped between flanges of the support profile in the longitudinal direction over an entire length of the support profile or the device carrier. In addition, a clamping arrangement with a clamping groove and a clamping spring, which extend in the longitudinal direction and can be brought into engagement with one another transversely to the longitudinal direction, can be provided on both sides. Appropriately, the respective clamping spring or clamping groove are then integrally formed on the outside on the flanges of the device carrier and the respective clamping groove or clamping spring on the inside on the flanges of the support profile. To the assembly of the device carrier on the To simplify the support profile, the equipment carrier can have a handle groove arrangement on both sides with a plurality of preferably parallel handle grooves. The respective grip groove arrangement extends on the outside on a flange of the device carrier in the longitudinal direction.

In an advantageous further development of the device carrier, it is provided that the device carrier is an extruded part formed from aluminum in an extrusion process. Alternatively, the equipment carrier can be a shaped sheet metal part formed from sheet steel.

In an advantageous development of the lamp according to the invention, it is provided that the at least one optics cover is centered on the device carrier by a centering arrangement in and transverse to the longitudinal direction and is fixed so that it can be extended in the longitudinal direction. Centering arrangement can for example comprise a centering formation and a centering recess which can be brought into engagement with one another transversely to the longitudinal direction. The respective centering recess or centering formation can then be formed on the optics cover and the respective centering formation or centering recess can be formed, for example, on the luminous support plate. As a result of the centering arrangement, optics arranged in the optics cover can be aligned relative to the multiple light sources of the light support plate and optical losses in the luminaire can thereby be reduced. The centering arrangement also does not prevent thermal expansion of the optics cover in the longitudinal direction and distortion of the optics cover during operation of the lamp can advantageously be prevented.

In an advantageous development of the optics cover, it is provided that the at least one optics cover has a plurality of integrally formed prisms. The optical cover is then preferably produced in an extrusion process. Alternatively, the at least one optical cover can be several integrally have molded lenses. The optics cover is then preferably produced in an injection molding process. The at least one optics cover can advantageously consist of several optics cover parts which are arranged one behind the other on the device carrier in the longitudinal direction. In particular, the production of an elongated optical cover in an injection molding process can thereby be simplified.

The optics cover can then advantageously have a centering arrangement which is integrated into the lenses. For example, one of the lenses can have a centering recess and the luminous support plate can have a centering formation which interlock and fix the lens on the luminous support plate in and across the longitudinal direction. In particular, in the event of thermal expansion of the light support plate and the optics cover, the lenses and the light sources can then remain centered with respect to one another and optical losses in the luminaire are advantageously reduced. Alternatively or additionally, the optics cover or also the optics cover parts can have at least one identification arrangement which is integrally formed on both sides of the optics cover transversely to the longitudinal direction. The identification arrangement can, for example, have an identification projection and an identification recess which can be brought into engagement with the identification projection, which prevents incorrect installation of the optical covers or the optical cover parts on one another in the longitudinal direction and also simplifies the installation of the lamp.

In summary, additional fastening means can be avoided in the luminaire according to the invention by the retaining clip and the assembly can thereby be simplified; the heat generated in the luminaire is preferably dissipated to the outside through the heat insulating space and the functionality of the luminaire is advantageously preserved; the interior of the light is protected from dirt particles by the seal and the optics cover is securely attached to the device carrier; and through the centering arrangement on the optics cover Thermal expansion of the optics cover is compensated and optical losses are advantageously reduced.

Fig. 1 shows a view of a lamp 1 according to the invention. The lamp 1 has an elongated U-shaped support profile 2 and an elongated U-shaped device carrier 3, which is fixed to the support profile 2 in a form-fitting manner. The equipment carrier 3 closes the support profile 2 transversely to the longitudinal direction 4 with a profile locking base 5, so that a profile interior 6 is formed in the support profile 2. The luminaire 1 also has an elongated optics cover 7, which is fixed to the device carrier 3. In this exemplary embodiment, the optics cover 7 has a plurality of prisms 8a formed integrally in the optics cover 7 and can be produced in an extrusion process. The optics cover 7 closes the device carrier 3 transversely to the longitudinal direction 4, so that a carrier interior 9 is formed in the device carrier 3.

Furthermore, the device carrier 3 has a luminous support base 10, which is arranged parallel to and at a distance from the profile locking base 5 and extends in the longitudinal direction 4. The light support base 10 divides the support interior 9 into a light interior 9a and a heat insulating space 9b. In the light interior 9a, a light support plate 11 with a plurality of light sources 12 is fixed on the light support base 10 on both sides by a retaining clip 13 in each case. Between the device carrier 3 and the optics cover 7, a seal 14 is arranged on both sides, which is supported on the optics cover 7 and on the device carrier 3 and seals the luminous interior 9a from the outside.

The support profile 2 has a current guide rail 15 with several electrical conductors 15a, which supply the several light sources 12 on the luminous support plate 11 with current. For this purpose, an electrical connection element - not visible here - is provided on the luminous support plate 11, by means of which the multiple light sources 12 on the luminous support plate 11 are electrically conductively connected to the conductors 15a of the power supply rail 15 via a control device 16. The control device 16 can control the multiple light sources 12 individually or in groups. The control device 16 is arranged in the profile interior 6 and is supported on the profile locking base 5. The profile interior is through the heat insulating space 9b 6 with the control device 16 from the luminous interior 9a with the luminous support plate 11 is thermally insulated. In this way, in particular, direct heat transfer between the luminous support plate 11 with the multiple light sources 12 and the control device 16 can be reduced. In this way, the heat generated in the luminaire 1 can preferably be dissipated to the outside and the functionality of the luminaire 1 can advantageously be maintained. In this exemplary embodiment, the device carrier 3 is a shaped sheet metal part and the profile locking base 5 is integrally formed by two lateral projections 17a on the luminous support base 10 of the device carrier 3. The projections 17a face one another and extend in the longitudinal direction 4 over an entire length of the device carrier 3.

The equipment rack 3 is clamped in the support profile 2 on both sides. For this purpose, flanges 18 of the device carrier 3 are arranged in the profile interior 6 and clamped between flanges 19 of the support profile 2 in the longitudinal direction 4 over an entire length of the support profile 2 or the device carrier 3. In addition, a clamping arrangement 20 with a clamping spring 20a and a clamping groove 20b is integrally formed on both sides. The clamping spring 20a and the clamping groove 20b engage one another and extend in the longitudinal direction 4. In addition, the support profile 2 is supported on the equipment carrier 3 on both sides on a respective support formation 21. Furthermore, the device carrier 3 has a handle groove arrangement 22 on both sides with a plurality of preferably parallel handle grooves 23. The respective grip groove arrangement 22 extends on the outside on the respective flange 18 of the device carrier 3 in the longitudinal direction 4.

The luminous support plate 11 with the light sources 12 is arranged in the luminous interior 9a in contact with the luminous support base 10 and is pressed against the latter on both sides by the retaining clips 13. As a result, the light support plate 11 rests on the light support base 10 and the heat generated in the light support plate 11 by the light sources 12 can be dissipated to the outside through the device carrier 3. In this case, the luminous support base 10 is separated from the control device 16 by the heat insulating space 9b, so that a direct heat transfer between the luminous support plate 11 and the control device 16 is advantageously prevented. On both sides of the luminous support base 10, a guide formation 24 aligned in the luminous interior 9a is integrally formed, which centers the luminous support plate 11 in the luminous interior 9a transversely to the longitudinal direction 4.

The respective retaining clip 13 has a first support wing 25a and a second support wing 25b, which are connected to one another by a support edge 26. The respective retaining clip 13 is supported with the first support wing 25a on the luminous support plate 11, with the second support wing 25b on the optics cover 7 and with the support edge 26 on an elongated support contour 27 of the device carrier 3. The respective retaining clip 13 is resilient and presses the luminous support plate 11 against the luminous support base 10 through the first support wing 25a and the optics cover 7 against the luminous support plate 11 through the second support wing 25b. In this way, the luminous support plate 11 is fixed on the luminous support base 10 and the optics cover 7 on the luminous support plate 11. In addition, the optics cover 7 is pressed against the luminous support plate 11 by the seal 14, which is supported on one side on the device carrier 3 and on the other side on the optics cover 7. The retaining clip 13 is fixed to the support contour 27 of the device carrier 3 in the longitudinal direction 4 by a plurality of tips 28 formed integrally on the support edge 26.

The optics cover 7 encloses the light sources 12 fixed on the luminous support plate 11 transversely to the longitudinal direction 4 and the light sources 12 are thereby protected from contamination. The luminous interior 9a is also sealed off from the outside by the seal 14. The seal 14 can, for example, be elastic and injection-molded onto the optics cover 7. In addition, the lamp can 1 by cover caps - not shown here - be sealed on both sides in the longitudinal direction to the outside.

The optics cover 7 also has a centering recess 29b of a centering arrangement 29 on one of the lenses 8b, into which a centering recess 29a - here the light source 12 on the luminous support plate 11 - engages and in this way centers the lens 8b on the light source 12 and in and across to the longitudinal direction 4 on the light source 12. The thermal expansion of the optics cover 7 is not prevented to the side of the centering recess 29b and distortion of the optics cover 7 is advantageously avoided. The optics cover 7 can for example be produced in an injection molding process and consist of several optics cover parts arranged one behind the other in the longitudinal direction 4. In this exemplary embodiment, the optics cover 7 is shaped in such a way that the support profile 2, the device carrier 3 and other components of the lamp 1 according to the invention remain the same. The optical cover 7 shown here and the one in FIG FIGS. 1 and 2 Optical covers 7 shown in the lamp 1 according to the invention are interchangeable with one another.

Fig. 4 shows a view of the lamp 1 according to the invention in a different embodiment. In this exemplary embodiment, only the optics cover 7 has a structure that differs from the optics cover 7 in FIG Fig. 2 on. Otherwise, the structure of the lamp 1 shown here corresponds to the structure of the in Fig. 2 1. Alternatively, viewed as an alternative, only the device carrier 3 has a structure that differs from the device carrier 3 in FIG Fig. 3 on. Otherwise, the structure of the lamp 1 shown here corresponds to the structure of the in Fig. 3 shown lamp 1.

In this exemplary embodiment, the equipment carrier 3 is an extruded part formed from aluminum in an extrusion process. In contrast to the device carrier 3 in Fig. 3 Here the profile locking base 5 is integrally formed by the T-shaped projections 17b facing the support profile 2 on the luminous support base 10 of the device carrier 3. The device carrier 3 also has different from that in Fig. 3 The device carrier 3 shown has the intermediate flange 18a which divides the luminous interior 9a in the longitudinal direction 4. The respective optics cover 7 with the lenses 8b is fixed on one side between the flange 18 and the intermediate flange 18a of the device carrier 3. In this exemplary embodiment, the device carrier 3 is shaped in such a way that the respective optics cover 7, the support profile 2 and other components of the lamp 1 according to the invention remain the same. The equipment rack 3 shown here and the one in FIG Fig. 3 Device carrier 3 shown in the lamp 1 according to the invention can be interchanged with one another.

In addition, in contrast to that in FIG Fig. 2 The optics cover 7 shown has a plurality of lenses 8b formed integrally on the optics cover 7. The optics cover 7 also has the centering recess 29b of the centering arrangement 29 on one of the lenses 8b, through which the optics cover 7 is centered on the luminous support plate 11. The optics cover 7 can for example be produced in an injection molding process and consist of several optics cover parts arranged one behind the other in the longitudinal direction 4. In this exemplary embodiment, the optics cover 7 is shaped in such a way that the support profile 2, the device carrier 3 and other components of the lamp 1 according to the invention remain the same. The optical covers 7 shown here and those in FIG Fig. 2 Optical covers 7 shown in the lamp 1 according to the invention are interchangeable with one another.

Fig. 5 FIG. 11 shows a partial view of the device carrier 3 with the retaining clip 13 in a first embodiment, as shown in FIG FIGS. 1 to 4 is shown. In Fig. 6 is a View of the in Fig. 5 retaining clip 13 shown. The retaining clip 13 has the first support wing 25a and the second support wing 25b, which are connected to one another by the support edge 26. The respective retaining clip 13 is supported with the first support wing 25a on the luminous support plate 11, with the second support wing 25b on the optics cover 7 and with the support edge 26 on the elongated support contour 27 of the device carrier 3. The respective retaining clip 13 presses the luminous support plate 11 against the luminous support base 10 through the first support wing 25a and the optics cover 7 against the luminous support plate 11 through the second support wing 25b. In this way, the luminous support plate 11 is fixed on the luminous support base 10 and the optics cover 7 on the luminous support plate 11. As a result of the plurality of tips 28 formed integrally on the support edge 26, the retaining clip 13 is also fixed to the support contour 27 of the device carrier 3 in the longitudinal direction 4.

The first support wing 25a has a first beveled bevel region 30 and two second beveled bevel regions 31. The folded areas 30 and 31 are folded transversely to the longitudinal direction 4 and extend in the longitudinal direction 4. The first folded area 30 presses the luminous support plate 11 towards the luminous support base 10 and the two second folded regions 31 fix the luminous support plate 11 laterally on the luminous support base 10. The folded regions 30 and 31 act transversely to the longitudinal direction 4, so that the luminous support plate 11 is fixed on the luminous support base 10 such that it can be displaced in the longitudinal direction 4. In particular, a thermal expansion of the luminous support plate 11 in the longitudinal direction 4 can thereby be compensated and a distortion of the luminous support plate 11 during operation of the luminaire 1 can advantageously be prevented.

In summary, in the luminaire 1 according to the invention, the heat insulating space 9b prevents a direct heat transfer between the luminous support plate 11 and the control device 16, whereby the functionality of the luminaire 1 is advantageously preserved. The retaining clip 13 eliminates the need for additional fasteners and the assembly of the lamp 1 is significantly simplified. The seal 14 advantageously seals the light interior 9a to the outside and additionally supports the optics cover 7 in the device carrier 3. The centering arrangement 29 on the optics cover 7 enables the lenses 8b to be centered on the light sources 12 and does not prevent the optics cover 7 from thermal expansion. In particular, a distortion of the luminous support plate 11 can thereby be prevented and optical losses in the luminaire 1 can advantageously be reduced.
