Abstract

The invention relates to an optoelectronic module, comprising a housing ( 11 ) having a first housing part ( 11 ) having a first cover surface ( 11 a ) and an opening ( 4 ); a mechanically flexibly designed organic light source ( 2 ) having an illuminating surface ( 2 a ); and a cover element ( 3 ) which is mounted on the illuminating surface ( 2 a ) and has a light-transmissive surface ( 3 a ) facing away from the illuminating surface ( 2 a ), wherein the organic light source ( 2 ) is introduced at least at some points into the opening ( 14 ), the first cover surface ( 11 a ) is curved and/or bowed, the size of the illuminating surface ( 2 a ) is at least 1 cm 2 , preferably at least 5 cm 2 , and the distance between the illuminating surface ( 2 a ) and the first cover surface ( 11 a ) is at most 1 cm, preferably at most 5 mm.

Claims (59)

1. An optoelectronic device comprising:

a housing having a first housing part comprising a first cover surface,

a mechanically flexible organic light source having an illuminating surface, and

a mechanically flexible cover element being applied to the illuminating surface and comprising a light passage surface facing away from the illuminating surface, wherein

the organic light source is introduced into the housing at least in places,

a size of the illuminating surface is at least 1 cm2, and

a distance between the illuminating surface and the first cover surface is at most 1 cm.

2. The optoelectronic device according to claim 1 , wherein

the cover element is adhesively bonded to the illuminating surface.

3. The optoelectronic device according to claim 1 , wherein

the cover element comprises a foil.

4. The optoelectronic device according to claim 1 , wherein

the cover element has a protruding region which projects laterally beyond the illuminating surface.

5. The optoelectronic device according to claim 1 , wherein

the cover element is connected to the housing.

6. The optoelectronic device according to claim 1 , wherein

the cover element has a protruding region which is connected to the housing.

7. The optoelectronic device according to claim 1 , wherein

the housing comprises the first housing part and a second housing part.

8. The optoelectronic device according to claim 1 , wherein

the housing comprises the first housing part and a second housing part, wherein

the first housing part and the second housing part are connected to one another in a mechanically detachable manner.

9. The optoelectronic device according to claim 1 , wherein

the housing comprises the first housing part and a second housing part, wherein the second housing part has a second cover surface which is curved or arched.

10. The optoelectronic device according to claim 1 , wherein

the first housing part has a first cover surface which is curved or arched.

11. The optoelectronic device according to claim 1 , wherein

the organic light source is bendable in a non-destructive manner around at least one first axis.

12. The optoelectronic device according to claim 11 , wherein

the organic light source is bendable at a radius of curvature which is at least 50 times the extent of the organic light source along a further axis.

13. The optoelectronic device according to claim 1 , wherein

the cover element is bendable in a non-destructive manner around at least one first axis.

14. The optoelectronic device according to claim 13 , wherein

the cover element is bendable at a radius of curvature which is at least 50 times the extent of the cover element along a further axis.

15. The optoelectronic device according to claim 1 , wherein

the housing comprises an opening in which the organic light source is introduced at least in places.

16. The optoelectronic device according to claim 1 , further comprising a mechanically flexible circuit board, which is at least partially arranged on a mounting surface of the organic light source that is facing away from the illuminating surface and which is electrically conductively connected to the organic light source.

17. The optoelectronic device according to claim 16 , wherein

the circuit board is bendable in a non-destructive manner around at least one first axis.

18. The optoelectronic device according to claim 16 , wherein

the organic light source, the cover element and the circuit board are bendable in a non-destructive manner around at least one first axis.

19. An optoelectronic device comprising:

a housing having

a first housing part comprising a first cover surface and

a second housing part, wherein the second housing part has a second cover surface which is curved or arched,

a mechanically flexible organic light source having an illuminating surface, and

a mechanically flexible cover element being applied to the illuminating surface and comprising a light passage surface facing away from the illuminating surface, wherein

the organic light source is introduced into the housing at least in places,

a size of the illuminating surface is at least 1 cm2, and

a distance between the illuminating surface and the first cover surface is at most 1 cm.

20. An optoelectronic device comprising:

a housing having a first housing part comprising a first cover surface,

a mechanically flexible organic light source having an illuminating surface, and

a mechanically flexible cover element being applied to the illuminating surface and comprising a light passage surface facing away from the illuminating surface, wherein

the organic light source is introduced into the housing at least in places,

a size of the illuminating surface is at least 1 cm2,

a distance between the illuminating surface and the first cover surface is at most 1 cm,

the organic light source is bendable in a non-destructive manner around at least one first axis, and

the organic light source is bendable at a radius of curvature which is at least 50 times the extent of the organic light source along a further axis.
