CONVERSION MATERIAL, ESPECIALLY FOR A WHITE OR COLORED LIGHT SOURCE COMPRISING A SEMICONDUCTOR LIGHT SOURCE, METHOD FOR PRODUCING THE SAME AND LIGHT SOURCE COMPRISING SAID CONVERSION MATERIAL

摘要

A conversion material for a white or colored light source is provided. The material includes a matrix glass that, as bulk material, for a thickness of about 1 mm, has a pure transmission of greater than 80% in the wavelength region from 350 to 800 nm and in the region in which the primary light source emits light, wherein the sum of transmission and reflection of the sintered matrix glass without luminophore is at least greater than 80% in the spectral region from 350 nm to 800 nm and in the spectral region in which the primary light source emits light.
