Led luminaire and arrangement comprising a luminaire body and an led operating device

The invention discloses an LED luminaire, in the case of which an LED module is applied to the luminaire body such that the height of the luminaire body and the LED module is ≦8 mm and the luminaire body at least partially forms the heat sink for the LED module. In this case, LED modules having power ratings of ≧3 watts are used. LED operating devices can be used for voltage supply purposes which form an outer face section of an arrangement comprising a luminaire body and an LED operating device, the total height of the luminaire body and LED operating device being ≦10 mm, and the LED operating device preferably being cooled via the luminaire body.

Background of the invention

[0002] LED modules such as DRAGONtape.RTM., DRAGONpuck.RTM. and DRAGONeye.RTM. are known which are used, for example, as shop and furniture luminaires, as reading lights and as spotlights for entertainment tasks or as a light head for miniradiators or as pilot lighting. In the case of such LED modules, the illuminance is lower and the light quality is poorer than in the case of burners. In addition, even the high-flux LED Golden Dragon.RTM. used already provides a minimum installation height which needs to be taken into consideration when designing the luminaire.

[0003] In the case of burners, the conventional axial arrangement of the lamp, the reflector and the lampholder prevents the luminaires from having a low height.
 

Brief summary of the invention

[0001] The present invention relates to LED luminaires having a luminaire body and at least one LED module, which is applied to the luminaire body. It relates further to an arrangement comprising a luminaire body and an LED operating device.

Claims


1. A luminaire having a luminaire body and at least one LED module, which is applied to the luminaire body, wherein the luminaire body, with the at least one LED module, has a height of .ltoreq.8 mm, and the luminaire body at least partially forms the heat sink for the LED module.

2. The luminaire as claimed in claim 1, the LED module having been produced using the chip-on-board technology, having a large number of light-emitting diodes and having a power rating of .gtoreq.3 watts, preferably .gtoreq.5 watts.

3. The luminaire as claimed in claim 1 having an optical system, which is provided directly above the LED module, for the purpose of deflecting light and for the purpose of protecting the LED module, the height h of the luminaire body with the LED module and the optical system being .ltoreq.8 mm.

4. The luminaire as claimed in claim 1, the LED module being recessed into the luminaire body.

5. The luminaire as claimed in claim 1, an anti-glare device being provided on the luminaire body so as to at least partially surround the LED module.

6. The luminaire as claimed in claim 5, the anti-glare device having a partially transparent component.

7. The luminaire as claimed in claim 1, the luminaire body having an aluminum or copper plate or an extruded section.

8. The luminaire as claimed in claim 1, the power supply to the LED module being provided by means of flat conductors on the luminaire body.

9. The luminaire as claimed in claim 1, the power supply to the LED module being formed by cables in at least one channel in the luminaire body.

10. An arrangement comprising a luminaire body and an LED operating device, it being possible for the LED operating device to be inserted in a receptacle of the luminaire body in an interlocking or force-fitting manner such that it forms an outer face section of the arrangement.

11. The arrangement as claimed in claim 10, at least one side face of the luminaire body extending flush with the LED operating device, and the height of the LED operating device, which has been applied to the luminaire body, together with the luminaire body, being .ltoreq.10 mm.

12. The arrangement as claimed in claim 10, the LED operating device having a piezoelectric transformer.

13. The arrangement as claimed in claim 10, it being possible for the LED operating device to be inserted in the receptacle in the luminaire body in such a manner that two opposite side faces of the luminaire body extend essentially flush with the LED operating device.

14. The arrangement as claimed in claim 13, the LED operating device being in the form of an end piece in such a manner that at least three side faces of said LED operating device extend flush with at least three side faces of the luminaire body in the state in which the LED operating device is inserted in the luminaire body.

15. The arrangement as claimed in claim 13, the LED operating device being in the form of a mechanical and electrical connecting piece between two luminaire body sections, and its longitudinal dimension L being approximately the sum of the depths T1, T2 of the respective cutouts in each of the luminaire body sections.

16. The arrangement as claimed in claim 10, the LED operating device being designed in such a manner that the LED operating device can be cooled at least partially by the luminaire body.

17. The arrangement as claimed in claim 10, the LED operating device having a preferably dovetailed cutout, it being possible for the LED operating device to be pushed onto the luminaire body via said cutout.

18. The luminaire as claimed in claim 1 having an arrangement comprising a luminaire body and an LED operating device, it being possible for the LED operating device to be inserted in a receptacle of the luminaire body in an interlocking or force-fitting manner such that it forms an outer face section of the arrangement.

19. The luminaire as claimed in claim 18, the LED operating device having resilient contacts, which can be brought into contact with connection faces of flat conductors on the surface of the luminaire body in the state in which the LED operating device has been pushed onto the luminaire body.

20. The luminaire as claimed in claim 18, the luminaire body having electrical connections in its longitudinal direction, which can be connected to electrical connections of the LED operating device in the longitudinal direction of the luminaire body.
