摘要:
A radiation-emitting optoelectronic component (1) which is connected to a heat sink (3) and is intended for pulsed operation with the pulse duration D, and in which temperature changes of the optoelectronic component (1) take place with a thermal time constant τ during pulsed operation. The thermal time constant τ is matched to the pulse duration D in order to reduce the amplitude of the temperature changes.

摘要:
An optoelectronic component includes a component housing and a body comprising a carrier substrate and a radiation emitting layer sequence. In certain embodiments, the body is arranged in a reflector cup of the component housing and is electrically conductively connected to external electrical leads of the component housing. The component housing can also be further provided with a lens that produces a desired aperture angle for the radiation cone. Uses for the component are also described.
摘要:
A method for patterned metallization of a plastic-containing body, which comprises the steps of producing the body via a two-component injection-molding process with at least two plastics, one of which is non-metallizable, and metallizing the body in such a way that a metallized region and a non-metallized region are formed, wherein the non-metallized region is determined by the non-metallizable plastic. A method for the patterned metallization of a plastic-containing body in particular a package body for an optoelectronic device is also provided.
