Title (EN) WHITE LIGHT-EMITTING LAMP AND ILLUMINATING DEVICE USING THE SAME
(FR) LAMPE ÉMETTANT UNE LUMIÈRE BLANCHE ET DISPOSITIF D'ÉCLAIRAGE UTILISANT CELLE-CI
(JA) 白色発光ランプとそれを用いた照明装置
Abstract: front page image
(EN)Disclosed is a white light-emitting lamp (1) comprising a light-emitting section (9) emitting white light when excited by the light emitted from a semiconductor light-emitting element (2). The light-emitting section (9) contains a blue phosphor, a yellow phosphor and a red phosphor. The yellow phosphor is composed of an europium and manganese activated alkaline earth silicate phosphor having a composition expressed as (Sr1-x-y-z-u,Bax,Mgy,Euz,Mnu)2SiO4 (wherein 0.1 ≤ x ≤ 0.35, 0.025 ≤ y ≤ 0.105, 0.025 ≤ z ≤ 0.25, 0.0005 ≤ u ≤ 0.02).
(FR)L'invention concerne une lampe (1) émettant une lumière blanche comprenant une section (9) émettant de la lumière qui émet une lumière blanche lorsqu'elle est excitée par la lumière émise à partir d'un élément (2) émettant de la lumière semi-conducteur. La section (9) émettant de la lumière contient un luminophore bleu, un luminophore jaune et un luminophore rouge. Le luminophore jaune est composé d'un luminophore de silicate alcalino-terreux activé par europium et manganèse, ayant une composition exprimée comme étant (Sr1-x-y-z-u, Bax, Mgy, Euz, Mnu)2SiO4 (où 0,1 £ x £ 0,35, 0,025 £ y £ 0,105, 0,025 £ z £ 0,25, 0,0005 £ u £ 0,02).
(JA) 白色発光ランプ1は、半導体発光素子2から出射された光により励起されて白色光を発光する発光部9を具備する。発光部9は青色蛍光体と黄色蛍光体と赤色蛍光体とを含む。黄色蛍光体は、(Sr1-x-y-z-u,Ba,Mg,Eu,MnSiO(0.1≦x≦0.35、0.025≦y≦0.105、0.025≦z≦0.25、0.0005≦u≦0.02)で表される組成を有するユーロピウムおよびマンガン付活アルカリ土類珪酸塩蛍光体からなる。
