Abstract

A lamp is disclosed. In an embodiment, the lamp includes a first light source and a second light source embodied as a light-emitting reflector, with a reflective layer and an electroluminescent layer sequence. The second light source is deformable such that an emission pattern of light emitted by the first light source and reflected by the light-emitting reflector is modifiable.

Claims

1-10. -10. (canceled)

11. A lamp comprising:

a first light source; and

a second light source embodied as a light-emitting reflector with a reflective layer and an electroluminescent layer sequence, wherein the second light source is deformable such that an emission pattern of light emitted by the first light source and reflected by the light-emitting reflector is modifiable.

12. The lamp according to claim 11, wherein the electroluminescent layer sequence comprises an organic functional layer stack with at least one organic light-emitting layer.

13. The lamp according to claim 12, wherein the organic functional layer stack is arranged between two electrodes.

14. The lamp according to claim 13, wherein the reflective layer comprises one of the electrodes.

15. The lamp according to claim 12, wherein the organic functional layer stack is formed in a large-area fashion over the reflective layer.

16. The lamp according to claim 11, wherein the electroluminescent layer sequence comprises an organic light-emitting diode.

17. The lamp according to claim 11, wherein the first light source is spaced apart from the second light source.

18. The lamp according to claim 11, wherein the first light source is a point light-type light source.

19. The lamp according to claim 18, wherein the first light source comprises an inorganic light-emitting diode.

20. The lamp according to claim 18, wherein the first light source comprises an incandescent lamp.

21. The lamp according to claim 18, wherein the first light source comprises a gas discharge lamp.

22. The lamp according to claim 11, wherein the lamp is part of a motor vehicle headlight.

23. The lamp according to claim 11, wherein the lamp is part of a flashlight.

24. The lamp according to claim 11, wherein the lamp is part of a head torch or headlamp.
