Description
図1(a)は、第1実施形態の半導体発光装置1の模式断面図である。
図1(b)は、図1(a)において破線Aで囲む部分の模式拡大図である。
半導体層15の第1の面15a側に設けられる光学層としては、蛍光体層に限らず、図4(a)に示すように、散乱層35であってもよい。
また、図4(b)に示すように、半導体層15の側面15cの周囲の領域に、金属膜ではなく、白色樹脂膜57を設けてもよい。白色樹脂膜57は、発光層13の放射光、蛍光体の放射光、散乱材による散乱光に対して反射性を有する。
以上説明した実施形態は、図16(a)及び(b)に示すサイドビュータイプの半導体発光装置4にも適用することができる。
図16(b)は、第4実施形態の半導体発光装置4を実装基板310上に実装した構成を有する発光モジュールの模式断面図である。
