Description

本発明の発光装置は、光源と、光源から出射された光が波長変換する波長変換部材とを有する発光装置であって、波長変換部材が、洗浄処理及び／または被覆処理を施した蛍光体を、モル百分率で、ＳｉＯ２：３０〜５０％、Ｌｉ２Ｏ：０〜１５％、Ｎａ２Ｏ：０〜１０％、Ｋ２Ｏ：０〜１０％、Ｌｉ２Ｏ＋Ｎａ２Ｏ＋Ｋ２Ｏ：２０〜３０％、Ｂ２Ｏ３：５〜１５％、ＭｇＯ：０〜１０％、ＢａＯ：０〜１０％、ＣａＯ：０〜１０％、ＳｒＯ：０〜１０％、Ａｌ２Ｏ３：０〜１０％、ＺｎＯ：０〜１５％、ＴｉＯ２：１０〜２０％、Ｎｂ２Ｏ５：１〜５％、Ｌａ２Ｏ３：０〜５％、ＴｉＯ２＋Ｎｂ２Ｏ５＋Ｌａ２Ｏ３：１１〜２０％の組成のガラス材料中に含有させたことを特徴としている。
なお、耐候性の低下を抑えるには、ＴｉＯ２、Ｎｂ２Ｏ５、及びＬａ２Ｏ３の合計量を１１％〜２０％にすることが望ましい。
