Abstract

An optoelectronic apparatus comprises a transparent first cover, at least two carriers mounted on the first cover, wherein a plurality of optoelectronic elements configured to emit light are attached to each of the at least two carriers, and a second cover mounted on the at least two carriers, wherein the second cover has at least partially a lower optical transmittance than the first cover and/or the at least two carriers.

First claim

The invention claimed is:

1. An optoelectronic apparatus comprising:
a transparent first cover;
at least two carriers mounted on the first cover, wherein a plurality of optoelectronic elements configured to emit light are attached to each of the at least two carriers; and
a second cover mounted on the at least two carriers, wherein the second cover has at least partially a lower optical transmittance than the first cover and/or the at least two carriers.

2. The optoelectronic apparatus according to claim 1 , wherein the second cover has the lower optical transmittance in a region at an interface between two adjacent carriers of the at least two carriers compared to the optical transmittance in other regions.

3. The optoelectronic apparatus according to claim 1 , wherein dots or a pattern are printed on the second cover, or the second cover comprises light absorbing particles.

4. The optoelectronic apparatus according to claim 1 , wherein a gap between two adjacent carriers of the at least two carriers is filled with a material having an optical transmittance identical or similar to the optical transmittance of the at least two carriers and/or a refraction index identical or similar to the refraction index of the at least two carriers.

5. The optoelectronic apparatus according to claim 1 , wherein the first cover is made of a glass and/or a plastic material.

6. The optoelectronic apparatus according to claim 1 , wherein the second cover is made of a glass, a carrier, and/or a plastic material.

7. The optoelectronic apparatus according to claim 1 , wherein the optoelectronic apparatus comprises a roof lining, a panoramic roof, a windscreen, a rear window, or a side window for a vehicle.

8. A vehicle comprising an optoelectronic apparatus according to claim 1 .

9. A window of a vehicle, comprising:
a transparent first cover;
at least two carriers mounted on the first cover;
wherein a plurality of optoelectronic elements configured to emit light are attached to each of the at least two carriers; and
wherein a gap between two adjacent carriers of the at least two carriers is filled with a material having an optical transmittance identical or similar to the optical transmittance of the two carriers and/or a refraction index identical or similar to the refraction index of the two carriers.

10. The window according to claim 9 , further comprising a transparent second cover mounted on the at least two carriers.

11. An optoelectronic apparatus comprising:
a transparent first cover;
at least two carriers mounted on the first cover;
wherein a plurality of optoelectronic elements configured to emit light are attached to each of the at least two carriers; and
wherein the optical transmittance of each of the carriers is varied in the direction of a gap between the respective carrier and an adjacent carrier.

12. The optoelectronic apparatus according to claim 11 , wherein the optical transmittance of each of the carriers is increased in the direction of the gap between the respective carrier and the adjacent carrier.

13. The optoelectronic apparatus according to claim 11 , wherein the optical transmittance of each of the carriers is varied by a perforation in the respective carrier and/or a pattern printed on the respective carrier.

14. The optoelectronic apparatus according to claim 11 , further comprising a transparent second cover mounted on the at least two carriers.

15. The optoelectronic apparatus according to claim 11 , wherein the first cover is made of a glass and/or a plastic material.

16. The optoelectronic apparatus according to claim 11 , wherein the second cover is made of a glass, a carrier, and/or a plastic material.

17. The optoelectronic apparatus according to claim 11 , wherein the optoelectronic apparatus comprises a roof lining, a panoramic roof, a windscreen, a rear window, or a side window for a vehicle.

18. A vehicle comprising the optoelectronic apparatus according to claim 11 .

19. A method for manufacturing an optoelectronic apparatus, comprising:
mounting at least two carriers on a transparent first cover, wherein a plurality of optoelectronic elements configured to emit light are attached to each of the at least two carriers; and
mounting a second cover on the at least two carriers, wherein the second cover has at least partially a lower optical transmittance than the first cover and/or the at least two carriers.

20. A method for manufacturing a window of a vehicle, comprising:
mounting at least two carriers on a transparent first cover, wherein a plurality of optoelectronic elements configured to emit light are attached to each of the at least two carriers; and
filling a gap between two adjacent carriers of the at least two carriers with a material having an optical transmittance identical or similar to the optical transmittance of the two carriers and/or a refraction index identical or similar to the refraction index of the two carriers.

21. A method for manufacturing an optoelectronic apparatus, comprising:
mounting at least two carriers on a transparent first cover;
wherein a plurality of optoelectronic elements configured to emit light are attached to each of the at least two carriers; and
wherein the optical transmittance of each of the carriers is varied in the direction of a gap between the respective carrier and an adjacent carrier.

22. An optoelectronic apparatus, comprising:
a transparent first cover,
at least two carriers mounted on the first cover, wherein a plurality of optoelectronic elements configured to emit light are attached to each of the at least two carriers, and
a second cover mounted on the at least two carriers, wherein the second cover has at least partially a lower optical transmittance than the first cover and/or the at least two carriers,

and/or
a transparent first cover,
a first layer segment, in particular intermediate layer segment, arranged on the transparent first cover and comprising at least one optoelectronic element,
a second layer segment, in particular intermediate layer segment, arranged on the transparent first cover adjacent to the first layer segment along a first direction,
wherein the first and the second layer segment comprise an approximately similar refractive index,
wherein the first and the second layer segment are joined together along the first direction by a melted or dissolved and resolidified material,

and/or
an at least partially transparent first cover,
a second cover,
at least one first layer segment, in particular intermediate layer segment, which is arranged between the first cover and the second cover, and which carries an arrangement of a plurality of optoelectronic light sources,
wherein the arrangement of the plurality of optoelectronic light sources has a defined shape with a defined contour, and
wherein the first layer segment has the same shape and the same contour as the arrangement of the plurality of optoelectronic light sources.
