Light source used as a luminescence conversion-LED has a polycrystalline ceramic body acting completely or partially as a phosphor

摘要

Light source (1) comprises an LED (2) for emitting a primary radiation (4), and a luminescence conversion body (3) for converting the primary radiation into a secondary radiation (5). The luminescence conversion body is a polycrystalline ceramic body acting completely or partially as a phosphor whilst a part of the base material forming the ceramic body is activated by a dopant. An Independent claim is also included for a process for the production of the light source.
