<P>PROBLEM TO BE SOLVED: To provide a phosphor composite member having excellent heat resistance, high color rendering properties, and color control capabilities for various colors from daylight colors to light-bulb colors, and capable of achieving high emission intensity. <P>SOLUTION: The phosphor composite member is constituted by forming an inorganic powder sintered body layer containing SnO-P<SB POS="POST">2</SB>O<SB POS="POST">5</SB>based glass and an inorganic phosphor powder 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. <P>COPYRIGHT: (C)2012,JPO&INPIT |
