GLASS-SEALED LIGHT EMITTING ELEMENT INCLUDING PHOSPHOR, CIRCUIT SUBSTRATE WITH GLASS-SEALED LIGHT EMITTING ELEMENT, METHOD OF MANUFACTURING GLASS-SEALED LIGHT EMITTING ELEMENT, AND METHOD OF MOUNTING GLASS-SEALED LIGHT EMITTING ELEMENT

PROBLEM TO BE SOLVED: To obtain white light emission performance and excellent sealing properties. SOLUTION: A blue light emitting diode chip and a glass member closely adhered to at least part of the surface of the light emitting diode chip are provided. Inside the glass member, a phosphor is included, which is YAG having a homogeneous primary particle diameter of 0.01 to 30 μm and coated with silica formed by the sol-gel method, and at least part of the surface form of the glass member is curved. The curved surface is preferably part of a sphere or ellipsoid of revolution. The surface form of the glass member is composed of a spherical part and a flat part, and the diode chip is disposed preferably on the flat part. COPYRIGHT: (C)2008,JPO&INPIT
