ABSTRACT:
A radiation emitter component, in particular an infrared emitter component with a conventional light-emitting diode housing, includes two electrode connections, one of which has a well-shaped reflector. The housing has an optically transparent, electrically non-conducting encapsulation material. A semiconductor laser chip is fastened in a well-shaped reflector of the light-emitting diode housing. The semiconductor laser chip has a quantum well structure, in particular with a strained layer structure, for example MOVPE epitaxial layers with a layer sequence GaAlAs-InGaAs-GaAlAs. A diffusor material can be inserted into the optically transparent, electrically non-conducting material of the light-emitting diode housing. The diffusor material is constructed or inserted with regard to type and concentration in such a way that in connection with the semiconductor laser chip encapsulated in the light-emitting diode housing, a radiation characteristic curve or an increase of an effective emission surface is produced that is comparable to that of a conventional infrared light-emitting diode.
