Lighting device, backlighting device, and display device

1. A lighting arrangement with a light module comprising:

at least one first group of light sources and one second group of light sources arranged spaced apart from each other on a flexible circuit board;

a carrier on which the light module is mounted; and

a buffer zone between the first and the second group of light sources, which buffer zone laterally overlaps with the light module;

wherein at least one of the light sources includes a light-emitting semiconductor chip; and

wherein the light-emitting semiconductor chip is comprised in at least one of a housing and an encapsulation of an optoelectronic component, and the optoelectronic component is mounted on the flexible circuit board.

2. The lighting arrangement according to claim 1 , wherein the flexible circuit board includes a bend or a fold on a back side of the carrier, in a region of the buffer zone.

3. The lighting arrangement according to claim 2 , wherein the flexible circuit includes a U-shaped bend on the back side of the carrier, in the region of the buffer zone.

4. The lighting arrangement according to claim 1 , wherein the lighting arrangement emits light from a front side of the carrier, and wherein, in a region of the buffer zone, the flexible circuit board extends, at least in some places, at a back side of the carrier, the back side being arranged opposite the front side.

5. The lighting arrangement according to claim 2 , wherein the first and the second groups of light sources are arranged on a front side of the carrier, the carrier includes, in the region of the buffer zone, an opening, and the flexible circuit board extends through the opening to the back side of the carrier, the back side being arranged opposite the front side.

6. The lighting arrangement according to claim 1 , wherein, in a top view of the carrier, the first group of light sources is arranged in an opening of the carrier.

7. The lighting arrangement according to claim 6 , wherein, in a top view of the carrier, the second group of light sources is arranged in a further opening and the buffer zone is arranged between the opening and the further opening.

8. The lighting arrangement according to claim 6 , wherein a heat sink is arranged on a back side of the carrier and laterally overlaps with the first group of light sources and the opening.

9. The lighting arrangement according to claim 1 , wherein the light module is at least one of bonded and clamped with the carrier.

10. The lighting arrangement according to claim 8 , wherein the first group of light sources is locked in position with the carrier by the heat sink.

11. The lighting arrangement according to claim 1 , wherein the light-emitting semiconductor chip is mounted directly on the flexible circuit board.

12. The lighting arrangement according to claim 1 , wherein the first group of light sources and the second group of light sources are rotated by an angle α relative to each other.

13. The lighting arrangement according to claim 12 , wherein the flexible circuit board includes at least one of a fold and bend between the first and the second group of light sources.

14. The lighting arrangement according to claim 1 , further comprising:

a reflective film or plate that covers at least one of the carrier and the light module, at least in places.

15. A backlighting device for a display device with a lighting arrangement according to claim 1 .

16. A display device with a backlighting device according to claim 15 .

17. A display device according to claim 16 , further comprising:

an image-generating display unit that is backlighted during operation by the lighting arrangement.

18. The display device according to claim 16 , wherein the display unit is an LCD panel.
