Abstract:
(EN) Provided are a wavelength conversion member and a wavelength conversion element that are capable of suppressing temporal reduction in light emission intensity or dissolution of a constituent material when being irradiated with light from a high-power LED or LD, and a light emitting apparatus using same. A waveform conversion member according to the present invention contains, in mass%, 70-99.9% of inorganic phosphor particles and 0.1-30% of easily sinterable ceramic particles, wherein the easily sinterable ceramic particles are interposed between the inorganic phosphor particles, and the inorganic phosphor particles are bound by the easily sinterable ceramic particles.
(FR) La présente invention concerne un composant de conversion de longueur d’onde et un élément de conversion de longueur d’onde qui sont capables de supprimer la réduction temporelle de l’intensité d’émission de lumière ou la dissolution d’un matériau constituant lorsque celui-ci est irradié avec une lumière provenant d’une LED ou LD à haute puissance, et un appareil d’émission de lumière utilisant ceux-ci. Un composant de conversion de forme d’onde selon la présente invention contient, en % en masse, 70 à 99,9 % de particules de luminophore inorganique et 0,1 à 30 % de particules de céramique aisément frittables, les particules de céramique aisément frittables étant intercalées entre les particules de luminophore inorganique, et les particules de luminophore inorganique étant liées par les particules de céramique aisément frittables.
(JA) 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波長変換素子、並びにそれを用い た発光装置を提供する。 質量%で、無機蛍光体粒子 70~99.9%、及び、易焼結性セラミック粒子 0.1~30%を含有する波長変換部材であって、 無機蛍光体粒子間に易焼結性セラミック粒子が介在しており、かつ、無機蛍光体粒子が易焼結性セラミック粒子により結着されていることを特徴とする波長変換部材。
