Classification: CPC H  F | IPC H

Claim 0:
1. An optoelectronic component comprising:
a continuous one-piece housing having a cutout; wherein the continuous one-piece housing comprises a bottom surface and two sidewall surfaces connected to the bottom surface where the two sidewall surfaces are at opposite ends of the bottom surface;
a layer sequence having an active layer configured to emit an electromagnetic primary radiation during operation of the component; wherein the layer sequence is arranged in the cutout; wherein the layer sequence has a radiation exit surface and side surfaces; wherein the layer sequence is arranged over the bottom surface of the continuous one-piece housing;
a conversion element arranged in the beam path of the electromagnetic primary radiation; wherein the conversion element comprises:
a conversion layer comprising a first matrix material and a converter material;
wherein the conversion layer is arranged in the cutout; and
a conversion potting arranged over the conversion layer comprising a second matrix material and a converter material; wherein the conversion potting has a thickness greater than a thickness of the conversion layer, wherein the thickness of the conversion potting and the thickness of the conversion layer are measured in a direction perpendicular to the bottom surface of the housing;
wherein there is a jump in concentration of converter material between the conversion layer and the conversion potting, and wherein the converter material is configured to at least partially convert the electromagnetic primary radiation into a yellow electromagnetic secondary radiation during operation of the component;
wherein the conversion layer comprises an amount of the converter material ranging from 80% to 97% relative to the total amount of converter material in the conversion element; and
wherein the conversion potting comprises an amount of the converter material ranging from 3% to 20% relative to the total amount of converter material in the conversion element.
