Abstract

A luminescent semiconductor component has a casing member of a light transmissive plastics material containing particles which simultaneously determine the light scattering and filtering properties of the light which is emitted by the semiconductor component and passes out of the casing member. The casing member may be of epoxy resin, and the particles may be of colored ground filter glass.

Claims

1. A luminescent semiconductor component comprising a light emitting semiconductor body and a casing member of light-transmissive plastics material enclosing said body, said casing member containing up to 20% by volume of particles which are comprised of a colored glass powder and which simultaneously determine the light scattering and filtering properties of said casing member with respect to light emitted by said body and passing through said casing member, and wherein the refractive index of said plastics material is substantially different from that of the material of said particles.
