Abstract

In an embodiment an optoelectronic lighting device includes a carrier, exactly one light-emitting optoelectronic semiconductor component, wherein the semiconductor component has a light emission area on at least one surface side, and wherein the semiconductor component is arranged on an upper side of the carrier, at least one functional layer arranged above the light emission area and/or adjacent to the light emission area and an edging for the functional layer, wherein the edging surrounds the functional layer when viewed in a circumferential direction, the circumferential direction being parallel to the upper side of the carrier around the functional layer, and wherein the edging is formed of a transparent material.

First claim

The invention claimed is:

1. An optoelectronic lighting device comprising:
a carrier;
at least one light-emitting optoelectronic semiconductor component arranged on an upper side of the carrier and comprising a light emission area on a surface side facing away from the carrier and a side surface perpendicular to the carrier;
a filling layer arranged on the upper side of the carrier and adjacent to the side surface of the semiconductor component in plan view;
at least one functional layer arranged on the light emission area and/or adjacent to the light emission area;
an intermediate layer arranged on the functional layer;
an edging surrounding the functional layer in plan view, wherein the edging comprises a transparent material; and
at least one cover layer arranged above the intermediate layer and the edging.

2. The optoelectronic lighting device according to claim 1 , wherein the edging surrounds the functional layer such that the functional layer is completely arranged within the edging when viewed in a direction parallel to the upper side of the carrier.

3. The optoelectronic lighting device according to claim 1 ,
wherein the edging comprises a surrounding border, in a center of which a continuous opening is provided, and
wherein the edging surrounds the functional layer such that the center of the border is arranged above the light emission area of the semiconductor component and/or above the center of the semiconductor component and the functional layer is at least partially arranged the opening.

4. The optoelectronic lighting device according to claim 1 ,
wherein a border of the edging has at least one outer surface arranged on a side surface of the lighting device, and
wherein the side surface and/or the outer surface of the border extend at least substantially perpendicular to the upper side of the carrier.

5. The optoelectronic lighting device according to claim 1 , wherein at least one outer surface of a border of the edging does not lie on a side surface of the lighting device but at least one edge layer is formed between the outer surface and the side surface.

6. The optoelectronic lighting device according to claim 1 , wherein the edging has a refractive index which is between a refractive index of the functional layer and a refractive index of air.

7. The optoelectronic lighting device according to claim 1 , wherein the edging is formed of a material comprising silicone or glass.

8. The optoelectronic lighting device according to claim 1 , wherein the functional layer is formed flat on its top side opposite to the upper side of the carrier or has a recess in the middle of the top side.

9. The optoelectronic lighting device according to claim 1 , wherein the cover layer is opaque and/or reflective with respect to the functional layer.

10. An optoelectronic lighting device comprising:
a carrier;
at least one light-emitting optoelectronic semiconductor component arranged on an upper side of the carrier and comprising a light emission area on a surface side facing away from the carrier;
a filling layer arranged on the upper side of the carrier;
at least one functional layer arranged on the light emission area and/or adjacent to the light emission area;
an intermediate layer arranged on the functional layer;
an edging surrounding the functional layer in plan view; and
at least one cover layer is arranged above the intermediate layer and the edging.

11. The optoelectronic lighting device according to claim 10 , wherein the edging surrounds the functional layer such that the functional layer is completely arranged within the edging when viewed in a direction parallel to the upper side of the carrier.

12. The optoelectronic lighting device according to claim 10 ,
wherein the edging comprises a surrounding border, in a center of which a continuous opening is provided, and
wherein the edging surrounds the functional layer such that the center of the border is arranged above the light emission area of the semiconductor component and/or above the center of the semiconductor component and the functional layer is at least partially arranged the opening.

13. The optoelectronic lighting device according to claim 10 ,
wherein a border of the edging has at least one outer surface arranged on a side surface of the lighting device, and
wherein the side surface and/or the outer surface of the border extend at least substantially perpendicular to the upper side of the carrier.

14. The optoelectronic lighting device according to claim 10 , wherein at least one outer surface of a border of the edging does not lie on a side surface of the lighting device but at least one edge layer is formed between the outer surface and the side surface.

15. The optoelectronic lighting device according to claim 10 , wherein the edging has a refractive index which is between a refractive index of the functional layer and a refractive index and air.

16. The optoelectronic lighting device according to claim 10 , wherein the edging is formed of a material comprising silicone or glass.

17. The optoelectronic lighting device according to claim 10 , wherein the functional layer is formed flat on its top side opposite to the upper side of the carrier or has a recess in the middle of the top side.

18. The optoelectronic lighting device according to claim 10 , wherein the cover layer is opaque and/or reflective with respect to the functional layer.
