Abstract
An optoelectronic component can be used for mixing electromagnetic radiation having different wavelengths, in particular in the far field. The optoelectronic component includes a carrier. A first semiconductor chip has a first radiation exit surface for emitting electromagnetic radiation in a first spectral range is provided on the carrier and a second semiconductor chip as a second radiation exit surface for emitting electromagnetic radiation in a second spectral range is provided on the carrier. A diffusing layer is provided on the radiation exit surfaces of the semiconductor chips which face away from the carrier.
Claims15
An optoelectronic component for mixing electromagnetic radiation having different wavelengths in a far field, the component comprising:
- a carrier;
- a first semiconductor chip arranged on the carrier and having a first radiation exit surface for emitting electromagnetic radiation in a first spectral range;
- a second semiconductor chip arranged on the carrier and having a second radiation exit surface for emitting electromagnetic radiation in a second spectral range;
- a diffusing layer overlying the radiation exit surfaces of the first and second semiconductor chips;
- a conversion layer between the radiation exit surfaces of the semiconductor chips and the diffusing layer;
- and
- a clear material arranged in the conversion layer above the first semiconductor chip, wherein the clear material extends from the first semiconductor chip to the diffusion layer, wherein the clear material directly adjoins the first radiation exit surface, the conversion layer and the diffusion layer, and wherein the clear material does not cover the second radiation exist surface.
