LIGHT-EMITTING APPARATUS USING PHOSPHOR SHEET

摘要

PROBLEM TO BE SOLVED: To provide a light-emitting apparatus having a laminated structure of phosphor sheets which are easy to laminate in a multilayer form and to match a color.

SOLUTION: A mixture of a phosphor powder, an organic system binder member and an inorganic system sintering assistant is formed into a desired configuration, then the organic system binder member is sintered and removed to obtain the phosphor sheets. The phosphor sheets are laminated so that a first phosphor sheet 5 including phosphor emitting fluorescence of a longer wavelength may be placed nearer to its light-emitting device than to a second phosphor sheet 6 including the phosphor emitting fluorescence of a shorter wavelength.
