Abstract

An optoelectronic component includes a carrier, and a light source arranged on a surface of the carrier, said light source including at least one luminous surface formed by at least one light-emitting diode, wherein a transparent converter-free spacer is arranged on the luminous surface such that a distance is formed between the luminous surface and a spacer surface of the spacer facing away from the luminous surface, and wherein the light source is potted by a potting compound such that the spacer surface is formed extending flush with a potting compound surface facing away from the surface of the carrier and a surface formed by a spacer surface and the potting compound surface is plane.

Claims (33)

1. An optoelectronic component comprising:

a carrier, and

a light source arranged on a surface of the carrier,

said light source comprising at least one luminous surface formed by at least one light-emitting diode, wherein

a transparent converter-free spacer is arranged on the luminous surface such that

a distance is formed between the luminous surface and a spacer surface of the spacer facing away from the luminous surface, and wherein

the light source and the spacer is potted up to the spacer surface by means of a potting compound such that the spacer surface is formed extending flush and level with a potting compound surface facing away from the surface of the carrier and a surface formed by means of the spacer surface and the potting compound surface is planar.

2. The optoelectronic component as claimed in claim 1 , wherein a converter layer which leaves the luminous surface open is arranged on the surface.

3. The optoelectronic component as claimed in claim 1 , wherein the spacer has an electrically insulating embodiment.

4. The optoelectronic component as claimed in claim 1 , wherein the light-emitting diode is electrically contacted on an upper side facing away from the surface of the carrier and wherein the spacer projects beyond the electrical contacting.

5. The optoelectronic component as claimed in claim 1 , wherein the spacer is a glass layer or a glass platelet.

6. The optoelectronic component as claimed in claim 1 , wherein a converter layer at least partly covering the luminous surface is arranged on the surface.

7. The optoelectronic component as claimed in claim 6 , wherein the converter layer is produced by means of screen printing or by means of potting.

8. The optoelectronic component as claimed in claim 6 , wherein a color scattering layer for creating a color by scattering light at a color scattering layer surface of the color scattering layer facing away from the surface is arranged on the converter layer.

9. An optoelectronic component comprising:

a carrier, and

a light source arranged on a surface of the carrier,

said light source comprising at least one luminous surface formed by at least one light-emitting diode, wherein

the light source is potted up to the luminous surface by means of a potting compound such that a potting compound surface facing away from the surface of the carrier is formed extending flush and level with the luminous surface and a surface formed by means of the luminous surface and the potting compound surface is planar, wherein a converter layer at least partly covering the luminous surface is arranged on the surface and wherein a color scattering layer for creating a color by scattering light at a color scattering layer surface of the color scattering layer facing away from the surface is arranged on the converter layer.

10. The optoelectronic component as claimed in claim 9 , wherein the converter layer is produced by means of screen printing or by means of potting.

11. The optoelectronic component as claimed in claim 9 , wherein the color scattering layer comprises titanium dioxide.

12. The optoelectronic component as claimed in claim 9 , wherein the color scattering layer has a layer thickness of between 1 μm and 40 μm.

13. A method for producing an optoelectronic component, comprising:

providing a carrier,

arranging a light source on a surface of the carrier, wherein the light source comprises at least one luminous surface formed by at least one light-emitting diode,

arranging a transparent converter-free spacer on the luminous surface such that a distance is formed between the luminous surface and a spacer surface of the spacer facing away from the luminous surface, and

potting the light source and the spacer up to the spacer surface by means of a potting compound such that the spacer surface is formed extending flush and level with a potting compound surface facing away from the surface of the carrier and a planar surface is formed by means of the spacer surface and the potting compound surface.

14. A method for producing an optoelectronic component, comprising:

providing a carrier,

arranging a light source on a surface of the carrier, wherein the light source comprises at least one luminous surface formed by at least one light-emitting diode,

potting the light source up to the luminous surface by means of a potting compound such that a potting compound surface facing away from the surface of the carrier is formed extending flush and level with the luminous surface and a planar surface is formed by means of the luminous surface and the potting compound surface,

arranging, on the layer, a converter layer at least partly covering the luminous surface, and

arranging, on the converter layer, a color scattering layer for creating a color by scattering light at a color scattering layer surface of the color scattering layer facing away from the layer.
