PHOSPHOR COMPOSITE MEMBER, LED DEVICE AND METHOD FOR MANUFACTURING PHOSPHOR COMPOSITE MEMBER

摘要

Disclosed is a phosphor composite member having excellent heat resistance and colour rendering properties etc. and having colour control capabilities for various colours from daylight colours to light-bulb colours. The phosphor composite member is constituted by forming an inorganic powder sintered body layer containing an inorganic phosphor powder and SnO-P2O5 based glass on the surface of a ceramic substrate. When excitation light is irradiated, the ceramic substrate and the inorganic powder sintered body layer emit fluorescence having mutually different wavelengths.
