Description
前記色変換部材が、前記発光素子の側部を囲むように筒形状に前記基板上に形成されており、前記反射部材が該筒形状の色変換部材の開口を塞ぐように配置され、かつ、該反射部材の前記発光素子に対向する側が錐体の形に形成されており、該反射部材で閉じられた前記色変換部材の内側の空間に透明な封止材が充填されており、
前記色変換部材の外径が前記基板から離れる方向に伴って小さくなるように前記色変換部材の側面が傾斜していることを特徴とする。
本発明は、図1に示した形状に限られない。すなわち、LEDデバイス10から出射される光の演色性が上がるよう、LEDチップ11が持っている配光特性に合わせて、色変換部材13や反射部材14の形状を変更することが好ましい。以下、その変更例を図3〜図5に示す。

12 基板
13 色変換部材
14 反射部材
15 ベース板
16、17 絶縁層
