<P>PROBLEM TO BE SOLVED: To provide an emission color converting member capable of producing a highly reliable, long lifetime white color illumination light source using a blue color LED element, especially a high output blue color LED element. <P>SOLUTION: The emission color converting member for converting a part of blue color light emitted from a blue color light source into yellow light and synthesizing it with the remaining blue color light to generate white color light in which an inorganic phosphor is dispersed into glass having a melting point higher than 500°C. An oxide phosphor, e.g. a Y<SB>3</SB>Al<SB>5</SB>O<SB>12</SB>based phosphor, is suitably employed as the inorganic phosphor. <P>COPYRIGHT: (C)2003,JPO |
