WAVELENGTH CONVERSION MEMBER AND LIGHT EMITTING DEVICE USING THE SAME
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
【課題】ハイパワーのＬＥＤやＬＤの光を照射した場合に、経時的な発光強度の低下や構成材料の溶解を抑制することが可能な波長変換部材、及びそれを用いた発光装置を提供する。【解決手段】波長変換部材１１は、蛍光体層１と、蛍光体層１の両面に形成され、蛍光体層１より高い熱伝導率を有する透光性放熱層２とを備える積層体からなることを特徴とする。【選択図】図１
