Claims (2)
- LEDチップと、LEDチップが実装されたベース部材と、LEDチップを封止した封止樹脂からなる封止部と、光出射面が凸曲面状に形成され封止部に重ねて配置されたレンズと、LEDチップから放射された光によって励起されてLEDチップの発光色とは異なる色の光を放射する蛍光体を透明材料とともに成形した成形品であってレンズの前記光出射面側にレンズを覆い前記光出射面との間に空気層が形成される形で配設されるドーム状の色変換部材とを備え、レンズは、前記光出射面が封止部側の光入射面から入射した光を前記光出射面と空気層との境界で全反射させない凸曲面状であり球面の一部により形成されており、当該球面の中心がLEDチップの厚み方向に沿った発光部の中心線上に位置するように配置されてなり、色変換部材は、内面が前記光出射面に沿った形状であり前記光出射面に対応した前記球面よりも直径が大きな球面の一部からなる形状に形成されており、レンズの光出射面の位置によらず法線方向におけるレンズの前記光出射面と色変換部材の内面との間の距離が略一定値となっていることを特徴とする発光装置。
- 前記LEDチップの発光色が青色であり、前記色変換部材の前記蛍光体として黄色蛍光体もしくは赤色蛍光体と緑色蛍光体とを用いてなることを特徴とする請求項1記載の発光装置。
