Abstract

An optoelectronic device includes a flexible organic light-emitting diode having a main extension plane, a first retaining element having a first major surface formed in accordance with a bent surface, and a second retaining element, wherein the OLED is arranged between the first retaining element and the second retaining element, and the OLED is mechanically fixed by the first retaining element and/or the second retaining element such that the main extension plane of the OLED is formed in accordance with the bent surface.

First claim

The invention claimed is:

1. An optoelectronic device comprising:
a flexible organic light-emitting diode having a main extension plane,
a first retaining element having a first major surface formed in accordance with a bent surface, and
a second retaining element, wherein
the OLED is arranged between the first retaining element and the second retaining element,
the OLED is mechanically fixed by the first retaining element and/or the second retaining element such that the main extension plane of the OLED is formed in accordance with the bent surface.

2. The optoelectronic device according to claim 1 , wherein the first retaining element and/or the second retaining element have a transparent light exit surface.

3. The optoelectronic device according to claim 1 , wherein the composite consisting of the OLED and the two retaining elements is embedded in a casting compound.

4. The optoelectronic device according to claim 1 , wherein the second retaining element is formed as a casting compound.

5. The optoelectronic device according to claim 1 , wherein the first retaining element and the second retaining element connect together in a mechanically stable and reversible manner by a connecting element.

6. The optoelectronic device according to claim 5 , wherein the connecting element is arranged in edge regions of the retaining elements.

7. The optoelectronic device according to claim 1 , wherein the first retaining element and/or the second retaining element are transparent.

8. The optoelectronic device according to claim 7 , wherein one of a logo, three-dimensional effects, scattering particles, luminescent particles, color filters, temperature-activated dyes and UV-activated dyes are incorporated into the transparent material.

9. The optoelectronic device according to claim 1 , wherein the first retaining element and/or the second retaining element include electrical contacts that electrically contact the OLED.

10. The optoelectronic device according to claim 1 , wherein the OLED comprises a flexible printed circuit board element guided through starting from an edge region of the OLED between the first retaining element and the second retaining element and electrically contacts the OLED.

11. The optoelectronic device according to claim 1 , wherein the first retaining element and/or the second retaining element comprise markings for recognition by a final assembly system.

12. The optoelectronic device according to claim 1 , wherein the first retaining element and/or the second retaining element are equipped with one of: temperature sensor, moisture sensor, acceleration sensor and light sensor.

13. An arrangement comprising:
at least one optoelectronic device according to claim 1 , and a holder in which the optoelectronic device is fastened.

14. The arrangement according to claim 13 , wherein the first retaining element and/or the second retaining element comprise a plug connector inserted into the holder and thus produces at least one mechanical connection, electrical connection or thermally conductive connection between the optoelectronic device and the holder.

15. The arrangement according to claim 13 , wherein a plurality of optoelectronic devices are fastened in the holder.

16. The arrangement according to claim 13 , wherein further light sources, a light-emitting diode, a laser, a halogen lamp or a xenon lamp are integrated.

17. The arrangement according to claim 13 , wherein the position of the optoelectronic device can vary within the holder.

18. A method of producing an optoelectronic device, comprising:
providing a flexible OLED having a main extension plane,
providing a first retaining element having a first major surface formed in accordance with a bent surface, and
fixing the OLED between the first retaining element and a second retaining element such that the main extension plane of the OLED is formed in accordance with the bent surface.

19. The method according to claim 18 , wherein fixing the OLED between the first retaining element and the second retaining element includes:
inserting the OLED into the first retaining element,
arranging a mold half such that a closed cavity is formed from the first retaining element and the mold half, said cavity surrounding the OLED,
injecting an injection-molding compound into the cavity, wherein the OLED is pressed against the first major surface of the first retaining element so that the main extension plane of the OLED is formed in accordance with the bent surface, and
hardening the injection-molding compound so that it forms the second retaining element.

20. A lamp for a motor vehicle comprising the optoelectronic device according to claim 1 .

21. An optoelectronic device comprising:
a flexible organic light-emitting diode having a main extension plane,
a first retaining element having a first major surface formed in accordance with a bent surface, and
a second retaining element, wherein
the OLED is arranged between the first retaining element and the second retaining element,
the OLED is mechanically fixed by the first retaining element and/or the second retaining element such that the main extension plane of the OLED is formed in accordance with the bent surface, and
no joining material is used to mechanically fix the OLED in the retaining elements.
