Description
board)型のものであって、図2,3に示すように基板11と、複数の半導体発光素子例えばLEDチップ21と、枠部25と、透光性の封止部材27、拡散層6を具備している。
封止部材27には図示しない蛍光体が適量混ぜられている。蛍光体は、LEDチップ21が発する光で励起されて、LEDチップ21が発する光の色とは異なる色の光を放射する。LEDチップ21が青色光を発する本実施例1では、発光装置10が白色光を出射できるようにするために、蛍光体に青色の光とは補色の関係にある黄色系の光を放射する黄色蛍光体が使用されている。このように蛍光体が混ぜられた封止部材27は、その蛍光体が発光するので、発光装置10の発光部をなす。
