COMPOSITE SHEET, LED PACKAGE USING THE SAME, AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a phosphor composite sheet capable of increasing heat resistance of an optical semiconductor element.SOLUTION: The composite sheet includes: a phosphor layer 3; and an adhesive layer 2 on the phosphor layer. The adhesive layer includes: a matrix resin and metal compound particles. When the metal compound particles are included in the adhesive layer, since thermal conductivity of the metal compound particles is higher than that of the resin, it becomes possible to increase thermal conductivity of the entire adhesive layer.
