Abstract
【解決手段】レーザー発光装置10に含まれる青色光を発するレーザーダイオードと、レーザーダイオードの発する光の一部を吸収して波長を変換する波長変換部11と、を有し、波長変換部11は、YAG系の単結晶蛍光体を含み、レーザーダイオードから発せられて波長変換部11に照射される光の放射照度が80W/mm2以上である、発光装置1を提供する。
【選択図】図2
Description
第1の実施の形態に係る発光装置は、波長変換部の光取出し面が被照射面(LDから発せられた光が照射される面)の反対側にある透過型構造を有する。
図2、図3は、第1の実施の形態に係る発光装置1、2の構成を示す模式図である。発光装置1、2は、青色光を発するLDを有するレーザー発光装置10と、レーザー発光装置10の発する光(レーザー発光装置10に含まれるLDの発する光)の一部を吸収して波長を変換する波長変換部11と、を有する。
第1の実施の形態に係る単結晶蛍光体は、Ceで付活されるYAG系単結晶蛍光体であり、(Y1−a−bLuaCeb)3+cAl5−cO12(0≦a≦0.9994、0.0002≦b≦0.0067、−0.016≦c≦0.315)で表される組成を有する。ここで、Ceは、Yサイトに置換され、付活剤として機能する(発光中心となる)。一方、Luは、Yサイトに置換されるが、付活剤としては機能しない。
本実施の形態の単結晶蛍光体の製造方法の一例として、CZ法による製造方法について以下に述べる。
図4〜13は、第1の実施の形態に係る波長変換部11の保持構造の例を示す断面図である。
第2の実施の形態に係る発光装置は、波長変換部の光取出し面が被照射面の反対側にない構造を有する。
図14、図15は、第2の実施の形態に係る発光装置3、4の構成を示す模式図である。発光装置3、4は、発光装置1、2と同様に、青色光を発するレーザーダイオードを有するレーザー発光装置10と、レーザー発光装置10に含まれるレーザーダイオードの発する光の一部を吸収して波長を変換する波長変換部11と、を有する。
図16〜20は、第2の実施の形態に係る波長変換部11の保持構造の例を示す断面図である。
第3の実施の形態は、第1の実施の形態及び第2の実施の形態の発光装置の使用例を示すものである。
上記実施の形態によれば、高出力のレーザーダイオードと高温下での量子効率や温度消光特性に優れる単結晶蛍光体を用いることにより、高輝度の発光装置を提供することができる。
