Description
1.光混合ユニットを照明装置ホルダーにおける傾斜角度が異なる各固定面に固定し、各光混合ユニットを互いに分散して配列することにより、異なる画素効果を実現する。
2.白色光LEDとカラー光LEDを同時に協調して用いることにより、十分な照度の提供を前提に、さらに各画素点に対してフルカラー調節機能を実現可能であり、かつ、単色LEDと白色光LEDの光混合作用によって、演色性が90%以上まで高められる。
3.LED照明装置本来の特性を十分に発揮し、蛍光灯と比較して省電力(電気消費量は蛍光灯の約10分の1)であり、衝撃に強く容易に破損せず、使用寿命が長い(白熱灯と蛍光灯の約20倍)。
4.放熱性能がよく、環境に優しく汚染が生じず、ちらつきがなく起動速度が速い。
