Abstract
Description
本発明は、独立請求項に記載した照明装置、照明制御装置および照明システムに関する。
本発明の目的は、LEDを用いて質が高く制御可能な照明を現出し得る、照明装置、照明制御装置および照明システムを提供することにある。
上述の照明装置などのための照明制御装置は、個別に制御された動作信号(電圧または電流)を異なる色のLEDに提供する、異なる色のLED用の制御可能な異なる電源、前記個別に制御された動作信号を異なる色のLEDに供給する、それぞれ異なる色のLED用の異なる出力端子、および、制御可能な電源用の個々の動作制御信号を生成する第1の制御手段を有する。動作制御信号は、温度信号および/または光強度信号に応じて生成されてもよく、これらの信号は、制御装置によって制御される照明装置から与えられるのが好ましい。
以下、添付の図面を参照しながら、本発明の特徴および実施形態について説明する。
上述の照明装置およびシステムは、通常のRGB装置では得ることのできない、質の高い制御可能な光を提供することが可能である。LEDは、波長および強度などの因子に基づいて選択することができる。この配置を使用し、2つの緑色LEDを用いることで、このような装置は、図10に示したように、可視色空間100の85%以上をカバーすることが可能である。外側の楕円形状102は、すべての可視波長を表し、一方、内側の三角形状104は、図1を参照して説明した装置を使用して生成することができる色を表す。中央の曲線106は、異なるすべての色温度において白色を生成するために、組み合わされるLEDのすべての組合せを表すので、「白線」(white line)と呼ばれる。良好な「太陽光」白色は、約5000〜6000Kの範囲内の色温度で得られる。
