Abstract

A light emitter with a radiation exit surface including a housing part with a receptacle, at least one organic optoelectronic device, arranged in the receptacle, and at least one cover part joined to the housing part, wherein the device is mounted between the cover part and the housing part.

Claims (44)

1. A light emitter with a radiation exit surface comprising:

a housing part with a receptacle,

at least one organic optoelectronic device arranged in the receptacle,

at least one cover part joined to the housing part, wherein the device is mounted between the cover part and the housing part, and

one or more external electrical terminal parts,

wherein

the device comprises a plurality of electrical contacts of the same polarity,

the contacts of the same polarity connect via a connecting conductor of a conductor part to a common external electrical terminal part, and

at least one of:

i. the conductor part connects electrically conductively to the device via an anisotropic electrically conductive layer, and

ii. the respective external electrical terminal part connects electrically conductively to the conductor part by solder.

2. A light emitter with a radiation exit surface comprising:

a housing part with a receptacle,

at least one organic optoelectronic device arranged in the receptacle,

at least one cover part joined to the housing part, and

a heat-conducting element is arranged on the device and connected thermally conductively to the device,

wherein the device is mounted between the cover part and the housing part,

the cover part comprises one or more thermal contact elements, via which the cover part connects thermally conductively to the device,

the heat-conducting element comprises a thermal land which, when viewed in plan view onto the radiation exit surface, is arranged next to the radiation exit surface, and

the thermal land connects thermally conductively to a thermal contact element of the cover part.

3. The light emitter according to claim 2 , with a maximum thickness of 8 mm or less.

4. The light emitter according to claim 2 , in which the cover part has a cut-out in a radiation passage region and in which the housing part has a cut-out in a region which overlaps with the radiation passage region.

5. The light emitter according to claim 2 , in which the cover part is of magnetic construction and is detachably fastened to the housing part by magnetic force.

6. The light emitter according to claim 2 , in which the respective external electrical terminal part is a connecting part for a jack plug connection.

7. The light emitter according to claim 2 , in which the device comprises a plurality of electrical contacts of the same polarity, and the contacts of the same polarity connect via a connecting conductor of a conductor part to a common external electrical terminal part.

8. The light emitter according to claim 7 , in which the conductor part connects electrically conductively to the device via an anisotropic electrically conductive layer.

9. The light emitter according to claim 7 , in which the conductor part is a flexible printed circuit board.

10. The light emitter according to claim 7 , in which the respective external electrical terminal part connects electrically conductively to the conductor part by solder.

11. The light emitter according to claim 2 , in which the cover part comprises a fixing element designed and arranged to safeguard one of the external electrical terminal parts against movement relative to the housing part.

12. The light emitter according to claim 2 , wherein

the device comprises a plurality of electrical contacts of the same polarity,

the contacts of the same polarity connect via a connecting conductor of a conductor part to a common external electrical terminal part, and

the conductor part is a flexible printed circuit board.

13. The light emitter according to claim 12 , wherein the flexible printed circuit board comprises a foil as printed circuit board conductor carrier.

14. The light emitter according to claim 12 , wherein the foil comprises Kapton.

15. The light emitter according to claim 12 , wherein the foil has a thickness of 350 μm or less.

16. A light emitter with a radiation exit surface comprising:

a housing part with a receptacle,

at least one organic optoelectronic device, arranged in the receptacle,

at least one cover part joined to the housing part, wherein the device is mounted between the cover part and the housing part, and

one or more external electrical terminal parts having at least one of:

i. one terminal part of the terminal parts is a male connecting part of an electrical plug connection and another terminal part of the terminal parts is a female connecting part of an electrical plug connection, and

ii. two terminal parts are oriented along an axis extending through the two terminal parts or the light emitter has a retaining device, and the retaining device and an electrical terminal part of the light emitter are oriented along a common axis extending through the retaining device and the terminal part,

wherein the cover part comprises one or more thermal contact elements, via which the cover part connects thermally conductively to the device, a heat-conducting element is arranged on the device and connected thermally conductively to the device, the heat-conducting element comprises a thermal land which, when viewed in plan view onto the radiation exit surface, is arranged next to the radiation exit surface, and wherein the thermal land connects thermally conductively to a thermal contact element of the cover part.
