LED WAVELENGTH CONVERSION MEMBER

摘要

PROBLEM TO BE SOLVED: To inexpensively provide a wavelength conversion member good in moisture resistance and high in durability, in an LED module using a remote phosphor technology in which a phosphor layer serving as a wavelength conversion member is disposed at a distance from a light-emitting element.SOLUTION: A wavelength conversion member good in moisture resistance and high in durability is inexpensively provided by including a structure where a glass material with a protective layer is arranged, the glass material being disposed on both faces of a phosphor layer including a phosphor dispersed in an epoxy resin or a silicone resin and the glass material being bonded with a glass material protective layer that is formed of a polycarbonate resin and has a thickness of 0.1-0.5 mm.SELECTED DRAWING: Figure 1
