Abstract

An illumination module may include at least one flexible carrier for a plurality of heat sources, including light sources, wherein the carrier is provided for being bent over at least part of its width.

Claims

1. An illumination module comprising at least one flexible carrier for a plurality of heat sources, including light sources, wherein the carrier is provided for being bent over at least part of its width.

2. The illumination module as claimed in claim 1, wherein the carrier is not provided for a bend at a strip running at least below the light sources, and is provided for a bend at at least one strip running laterally with respect to the light sources.

3. The illumination module as claimed in claim 2, wherein the carrier comprises at least one heat spreading area at least on the at least one strip running laterally with respect to the light sources.

4. The illumination module as claimed in claim 3, wherein at least part of the at least one heat spreading area is formed by at least one conductor track.

5. The illumination module as claimed in claim 1, wherein the at least one strip provided for a bend comprises at least one bearing area.

6. The illumination module as claimed in claim 1, comprising at least one expansion joint extending along a longitudinal direction of the carrier.

7. The illumination module as claimed in claim 1, comprising at least one reflector.

8. The illumination module as claimed in claim 7, wherein the reflector is present as a separately produced component or the reflector is applied in the form of a mirror layer on the carrier.

16. The illumination module as claimed in claim 1, wherein the at least one carrier is a tape-type carrier.

9. An illumination device comprising a bent support and at least one illumination module, the at least one illumination module comprising at least one flexible carrier for a plurality of heat sources, wherein the carrier is provided for being bent over at least part of its width, wherein the illumination module is fixed areally to the support at least regionally by a part of the carrier bent widthwise.

10. The illumination device as claimed in claim 9, wherein the support is embodied in the form of a tube and the at least one illumination module is arranged longitudinally in the tube such that the at least one illumination module s at least partly fitted to a curved inner side of the tube.

11. The illumination device as claimed in claim 9, wherein the light sources are arranged in a plurality of rows.

12. The illumination device as claimed in claim 10, wherein the at least one carrier bears by an underside on the tube.

13. The illumination device as claimed in claim 12, comprising at least one light passage window.

14. The illumination device as claimed in claim 13, wherein the at least one light passage window fixes the at least one carrier.

15. The illumination device as claimed in claim 10, wherein the at least one carrier bears by its top side on the tube and the light sources project into at least one leadthrough introduced in the tube.
