OPTICAL CONVERTER FOR HIGH LUMINANCES

摘要

The invention relates to an optical converter for producing colored or white light from blue excitation light (4). In addition to good conversion, the converter also has good scattering properties in order to be able to produce nearly white light from the scattered blue light components and the scattered, converted yellow light components (5). The converter material is a YAG ceramic or LuAG ceramic or a magnesium-aluminum ceramic having strong scattering.
