WAVELENGTH CONVERSION MEMBER AND LIGHT EMITTING DEVICE USING SAME

摘要

Provided are: a wavelength conversion member which is able to be suppressed in decrease of luminous intensity over time and in melting of a constituent material in cases where the wavelength conversion member is irradiated with light of a high-power LED or LD; and a light emitting device which uses this wavelength conversion member. A wavelength conversion member (11) is characterized by being formed of a laminate that is provided with 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).
