WAVELENGTH CONVERSION MEMBER AND LIGHT EMITTING DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide: a wavelength conversion member in which a decrease in luminous intensity with time and melting of a constituent material can be suppressed in cases where the wavelength conversion member is irradiated with light of a high-power LED or LD; and a light emitting device in which the wavelength conversion member is used.SOLUTION: A wavelength conversion member 11 is formed of a laminate including a phosphor layer 1 and light-transmitting heat dissipation layers 2 that are formed on both surfaces of the phosphor layer 1 and have a higher thermal conductivity than the phosphor layer 1.SELECTED DRAWING: Figure 1
