Conversion light emitting diode, for the conversion of primary radiation, includes a chip which emits primary radiation at a first wavelength and a powder containing fluorescent material

摘要

A conversion light emitting diode (LED) with a chip, which emits primary radiation of a first wavelength, especially a peak emission wavelength of 430-490 nm, and at least one powder containing fluorescent material, which absorbs at least part of the primary radiation and emits secondary radiation at a different wavelength. The mean particle size d 50of the fluorescent material is 0.1-1.5 Micro.
