Abstract

An organic luminous means and an illumination device comprising such a luminous means are specified. An optical display apparatus, emergency lighting, motor vehicle interior lighting, an item of furniture, a construction material, a glazing and a display comprising such a luminous means and, respectively, comprising an illumination device having such a luminous means are furthermore specified.

First claim

What is claimed:

1. A luminous means comprising:
a substrate having a first main surface, to which a first electrode is applied;
a second electrode;
an organic layer stack within an active region of the substrate between the first and the second electrode, wherein the organic layer stack comprises at least one organic layer which is suitable for generating light; and
a sensor adapted for determining the color locus and/or the brightness of a light.

2. The luminous means according to claim 1 , wherein the sensor is adapted for determining the color locus and/or the brightness of the light emitted by the luminous means during operation.

3. The luminous means according to claim 1 , wherein the sensor is a photodetector.

4. The luminous means according to claim 1 , wherein the sensor is arranged jointly with the organic layer stack of the luminous means on the first main surface of the substrate.

5. The luminous means according to claim 1 , wherein the sensor comprises a first electrode, a second electrode and a photodetecting layer sequence arranged between the two electrodes, wherein the photodetecting layer sequence comprises one layer which contains an organic material.

6. The luminous means according to claim 5 , wherein the sensor is produced jointly with the organic layer stack and the electrodes on the active region.

7. The luminous means according to claim 5 , wherein the sensor is constructed in the same way as the organic layer stack between the two electrodes.

8. The luminous means according to claim 1 , wherein the sensor and the organic layer stack are encapsulated by a shared encapsulation.

9. The luminous means according to claim 1 , comprising a controller configured for energizing the luminous means in a manner dependent on a measured value determined by the sensor.

10. The luminous means according to claim 9 , wherein the controller is arranged jointly with the organic layer stack of the luminous means on the first main surface of the substrate.

11. The luminous means according to claim 9 , wherein the controller contains an organic material.

12. The luminous means according to claim 9 , wherein the controller and the organic layer stack of the luminous means are encapsulated by a shared encapsulation.

13. The luminous means according to claim 9 , wherein the sensor, the controller and the organic layer stack of the luminous means are arranged jointly on the first main surface of the substrate.

14. An illumination device comprising:
at least two luminous means which are electrically and mechanically connected to one another;
a carrier mechanically connecting the luminous means of the illumination device to one another,
wherein each of said at least two luminous means comprises:
a substrate having a first main surface, to which a first electrode is applied,
a second electrode, and
an organic layer stack within an active region of the substrate between the first electrode and the second electrode, wherein the organic layer stack comprises at least one organic layer which is adapted for generating light.

15. The illumination device according to claim 14 , wherein the luminous means of the illumination device are electrically connected to one another by means of the carrier.

16. The illumination device according to claim 14 , wherein the carrier is embodied as one of the following components: carrier plate, carrier grid, cable system, rod system.

17. The illumination device according to claim 14 , wherein the carrier contains a textile material.

18. The illumination device according to claim 14 , wherein at least one luminous means is mechanically and electrically connected to the carrier by a connection location embodied as a connection pin or as a connection rail.

19. The illumination device according to claim 14 comprising:
a multiplicity of luminous means, wherein the luminous means are arranged in matrix-like fashion; and
a controller adapted for driving each of the luminous means independently of the remaining luminous means.

20. The illumination device according to claim 19 , wherein at least one of the luminous means is suitable for emitting light of a first color during a first time period and for emitting light of a second color during a second time period, wherein the first color differs from the second color.

21. An illumination device comprising:
at least two rigid luminous means which inherently have no flexibility, each of said at least two luminous means comprising:
a substrate having a first main surface, to which a first electrode is applied,
a second electrode,
an organic layer stack within an active region of the substrate between the first and the second electrode, wherein the organic layer stack comprises at least one organic layer which is suitable for generating light, and
a flexible matrix in which said at least two rigid luminous means are embedded,
wherein each of said at least two luminous means has its own substrate which is separate from the substrates of each other of said at least two luminous means, and
wherein the flexible matrix covers the substrate of each of said at least two luminous means on a side facing away from the first electrode.

22. The illumination device according to claim 21 , further comprising two flexible carriers between which the rigid luminous means and the material of the flexible matrix are arranged.

23. The illumination device according to claim 21 , wherein the flexible matrix is formed with a light-transmissive material which contains particles of at least one of the following materials: luminescence conversion material, color filter material, diffuser material.

24. The illumination device according to claim 21 , wherein conductor tracks for connecting the individual luminous means electrically to one another are arranged in the matrix material.
