Abstract
【解決手段】光発生部21と、光分析部31と、コントローラ51と、第1の通信インタフェース41とを有する照明ユニット20が開示される。光発生部21および光分析部31は、透明窓を有するハウジング内に収容される。光発生部21はLEDの複数のグループを含み、各グループは他のグループとは異なるスペクトルの光を発する。光分析部31は、各グループによって発生される光の輝度およびハウジングの外側の場所からくる光の輝度に関連する輝度信号を発生する。コントローラ51は、輝度信号に応じて各LEDを流れる電流を調整する。第1の通信インタフェース41は、照明ユニット20の動作中に照明ユニット20の外部の装置と通信してコマンドを受けるためにコントローラ51によって利用される。
