Abstract

　中空のユニットケース1の底面に光反射面部材2が配置され、ユニットケースの上面側に光反射面部材と対向して発光面部材3が配置され、光反射面部材と発光面部材とで挟まれる中空導光領域10を形成される。ユニットケースの側面には、赤色、緑色、青色それぞれを単色発光する多数個のLED7R、7B、7Gが列状に配列されて成るLED光源5が設けられる。ユニットケース1内の光反射面部材2条には、LED光源5から中空導光領域に入射した各色光の照度を計測するカラーセンサが設置される。このカラーセンサの計測データはLED制御回路に供給され、LED制御回路は各色光の照度に基づき、LED光源に含まれる各LED7R、7B、7Gの発光強度を制御する。
