Abstract

An optoelectronic semiconductor component comprising: a main body ( 100 ) having a recess; ( 102 ), a first optoelectronic element ( 104 ) and a second optoelectronic element; ( 106 ) a surface structured element; ( 110 ) and a filling compound ( 112 ) embedding the first optoelectronic element ( 104 ) and the second optoelectronic element ( 106 ) in the recess, wherein the surface structured element configures a surface of the filling compound ( 112 ) such that at least two domed regions ( 114, 116, 118 ) of the surface are formed.

First claim

The invention claimed is:

1. An optoelectronic semiconductor component comprising:
a main body having a recess, wherein the recess has a bottom and lateral inner faces;
a first optoelectronic element and a second optoelectronic element arranged in the recess;
a surface structuring element formed by a protrusion of the main body extending from a lateral inner face partially into the recess, producing a constriction in the recess such that the recess is divided in at least two contiguous regions; and
a filling compound embedding the first optoelectronic element and the second optoelectronic element in the recess, wherein the filling compound is a potting compound, and
wherein the surface structuring element configures a surface of the filling compound such that at least two domed concave regions of the surface are formed.

2. The optoelectronic semiconductor component as claimed in claim 1 , wherein the constriction in the recess has a width of more than 100μm.

3. The optoelectronic semiconductor component as claimed in claim 1 , wherein the constriction is formed by a first protrusion and a second protrusion, wherein the first protrusion extends from a first lateral inner face into the recess and the second protrusion extends from a second lateral inner face into the recess, wherein the first and the second lateral inner faces are arranged opposite to each other.

4. The optoelectronic semiconductor component as claimed in claim 1 , wherein at least one surface structuring element structures a continuous surface of the filling compound in at least two regions.

5. The optoelectronic semiconductor component as claimed in claim 1 , wherein the first optoelectronic element and the second optoelectronic element are each designed as radiation sources.

6. The optoelectronic semiconductor component as claimed in claim 5 , wherein the first optoelectronic element has a different emission spectrum to the second optoelectronic element.

7. The optoelectronic semiconductor component as claimed in claim 1 , wherein the potting compound comprises one of the following materials: epoxy, resin, acrylic resin, and silicone resin.

8. The optoelectronic semiconductor component as claimed in claim 1 , wherein the filling compound comprises a diffuse material.

9. The optoelectronic semiconductor component as claimed in claim 1 , wherein the filling compound comprises an absorber material.

10. An optoelectronic semiconductor component comprising:
a main body having a recess, wherein the recess has a bottom and lateral inner faces;
a first optoelectronic element and a second optoelectronic element arranged in the recess;
a surface structuring element formed by a protrusion of the main body extending from a lateral inner face into the recess at a distance from the bottom of the recess, said surface structuring element having a bridge shaped form; and
a filling compound embedding the first optoelectronic element and the second optoelectronic element in the recess,
wherein the filling compound is a potting compound, and
wherein the surface structuring element configures a surface of the filling compound such that at least two domed concave regions of the surface are formed.

11. The optoelectronic semiconductor component as claimed in claim 10 , wherein the bridge shaped structuring element has a circular cross-section.

12. An optoelectronic semiconductor component comprising:
a main body having a recess, wherein the recess has a bottom and lateral inner faces;
a first optoelectronic element and a second optoelectronic element arranged in the recess;
a surface structuring element, wherein the surface structuring element is not connected to the lateral inner faces of the recess; and
a filling compound embedding the first optoelectronic element and the second optoelectronic element in the recess,
wherein the filling compound is a potting compound, and
wherein the surface structuring element configures a surface of the filling compound such that at least two domed concave regions of the surface are formed.

13. The optoelectronic semiconductor component as claimed in claim 12 , wherein the surface structuring element is coupled to the bottom of the recess.
