Abstract
【解決手段】LEDチップ1と、LEDチップ1が実装されたベース部材たる実装基板10と、実装基板10におけるLEDチップの実装面側に配設される第1の色変換部材20と、第1の色変換部材20に対して実装基板10と反対側に配設される第2の色変換部材30とを備える。LEDチップ1から放射される第1の可視光(青色光)と、第1の色変換部材20によって第1の可視光から色変換された第2の可視光(赤色光)と、第2の色変換部材30によって第1の可視光から色変換された第3の可視光(緑色光)とを混色することで白色光を得ることができ、しかも、青色光と黄色光を混色する従来例に比較して、長波長領域の第2の可視光(赤色光)が増えるために演色性が向上する。
