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 (58)

1. An optoelectronic device comprising:

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

a mechanically flexible organic light emitting diode having a light emission surface emitting light produced by the organic light emitting diode, and

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

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

a size of the light emission surface is at least 1 cm 2 , and

a distance between the light emission 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 light emission 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 light emission 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
