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.

First claim

The invention claimed is:

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,
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 least one strip running laterally with respect to the light sources, and
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,
wherein at least part of the at least one heat spreading area is formed by at least one metallic conductor track, and
wherein substantially the at least one conductor track runs solely in the carrier strip provided for a bend,
wherein substantially no conductor tracks run in the strip running at least below the light sources,
wherein the conductor tracks are the electrical connection between at least one first light source of the light sources and at least one second light source of the light sources.

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

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

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

5. The illumination module as claimed in claim 4 , 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.

6. 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,
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, and
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,
wherein the support is embodied in the form of a substantially cylindrical tube and the at least one illumination module is arranged longitudinally in the tube such that the at least one illumination module is at least partly fitted to a curved inner side of the tube,
wherein substantially no conductor tracks run in the strip running at least below the light sources,
wherein the conductor tracks are the electrical connection between at least one first light source of the light sources and at least one second light source of the light sources.

7. The illumination device as claimed in claim 6 , wherein the light sources are arranged in a plurality of rows.

8. The illumination device as claimed in claim 6 , wherein the at least one carrier bears by an underside on the tube.

9. The illumination device as claimed in claim 8 , comprising at least one light passage window.

10. The illumination device as claimed in claim 9 , wherein the at least one light passage window fixes the at least one carrier.

11. The illumination device as claimed in claim 6 , 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.

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