Abstract

Disclosed is an illuminating system of flexible shape and comprising at least one LED disposed on a flexible carrier material, an optic being provided that permits uniform, directed and/or glare-free light emission.

Claims (36)

1. An illuminating system of flexible shape and comprising at least one LED disposed on a flexible carrier material, and an optic that permits uniform, directed and/or glare-free light emission;

wherein said carrier material with said at least one LED and said optic is received in at least one flexible hollow profile bar of substantially rectangular cross section, in which said LEDs are adjacently disposed and form a common light-emitting area;

wherein in order to mount the illuminating system, said hollow profile bar is insertable form-lockingly into a mounting profile;

wherein said hollow profile bar comprises at least one projection that engages in at least one guide channel of said mounting profile, or said hollow profile bar comprises at least one guide channel in which at least one projection of said mounting profile engages;

wherein the side walls of said mounting profile each comprise at least one channel in which an approximately U-shaped, fixedly disposable holder form-lockingly engages.

2. The illuminating system of flexible shape as in claim 1 , wherein said optic is a Fresnel lens.

3. The illuminating system of flexible shape as in claim 1 , wherein said optic is configured as a separate component.

4. The illuminating system of flexible shape as in claim 1 , wherein said optic is configured by means of a nano- and/or microstructured film.

5. The illuminating system of flexible shape as in claim 1 , wherein said optic comprises a macrostructure.

6. The illuminating system of flexible shape as in claim 1 , wherein said optic comprises convexities, corrugations, or knobs.

7. The illuminating system of flexible shape as in claim 1 , wherein said optic comprises an optically active fluid.

8. The illuminating system of flexible shape as in claim 1 , wherein said optic is made of rigid material.

9. The illuminating system of flexible shape as in claim 1 , wherein said optic is made of glass.

10. The illuminating system of flexible shape as in claim 1 , wherein said optic is held in place via a holder in such a way that it does not hinder deformation of said illuminating system.

11. The illuminating system of flexible shape as in claim 10 , wherein said holder comprises at least two support elements, which are disposed diametrically opposite each other, and is supported by them on said carrier material.

12. The illuminating system of flexible shape as in claim 1 , wherein said optic is mounted in such a way that its position in relation to said LED remains substantially unchanged during deformation of said illuminating system.

13. The illuminating system of flexible shape as in claim 1 , wherein said illuminating system comprises flat LEDs.

14. The illuminating system of flexible shape as in claim 1 , wherein said illuminating system comprises DRAGON®, TOPLED®, POINTLED® and/or SIDELED® type flat LEDs.

15. The illuminating system of flexible shape as in claim 1 , wherein said LEDs are configured as colored and/or color-changing.

16. The illuminating system of flexible shape as in claim 1 , wherein a flexboard and/or a film conductor is used as said carrier material.

17. The illuminating system of flexible shape as in claim 1 , wherein said LED is placed, unhoused, directly on said carrier material.

18. The illuminating system of flexible shape as in claim 1 , wherein said illuminating system comprises additional height-optimized components.

19. The illuminating system of flexible shape as in claim 1 , wherein at least one thin cooling element of high thermal conductivity is provided to dissipate heat from said LEDs.

20. The illuminating system of flexible shape as in claim 19 , wherein said cooling element is implemented as a cooling plate.

21. The illuminating system of flexible shape as in claim 1 , wherein said carrier material with said at least one LED and said optic is received in at least one flexible lamp envelope.

22. The illuminating system of flexible shape as in claim 21 , wherein said flexible lamp envelope is formed by at least one element from the group consisting of molded part, tube, film and deep-drawn film.

23. The illuminating system of flexible shape as in claim 1 , wherein said hollow profile bar is of a flexible plastic.

24. The illuminating system of flexible shape as in claim 23 , wherein said hollow profile bar is of PMMA.

25. The illuminating system of flexible shape as in claim 1 , wherein said hollow profile bar is closed endwise by an end piece and/or by a plug-type electrical connector system.

26. The illuminating system of flexible shape as in claim 25 , wherein said end piece and/or said plug connector system are configured in such a way that in the state of being mounted on said hollow profile bar, at least one of their lateral faces extends approximately flush with at least one lateral face of said hollow profile bar.

27. The illuminating system of flexible shape as in claim 1 , wherein said illuminating system is configured as a flat, pixel-type flat lamp comprising a multiplicity of LEDs.

28. The illuminating system of flexible shape as in claim 27 , wherein said flat, pixel-like flat lamp is a display.

29. The illuminating system of flexible shape as in claim 1 , wherein said LEDs are controllable individually via a control device.

30. The illuminating system of flexible shape as claim 1 , wherein said LEDs are controllable individually via a bus.

31. The illuminating system of flexible shape as in claim 1 , wherein an overall height of said illuminating system is 5 mm or less.

32. The illuminating system of flexible shape as in claim 1 , wherein an overall height of said illuminating system is 3 mm or less.
