Description
従来技術にかかる片方向LEDモジュール装置は、印加される交流電源110を整流するブリッジダイオード120と、ブリッジダイオード120に抵抗R1を介して結合される片方向LEDモジュール130とを含む。
ここで、抵抗R1は、片方向LEDモジュール130に流れる電流の大きさを決定する。
交流電源110の正の半周期電圧が印加されると、電圧の大きさがLEDモジュール130の順方向閾値電圧以上の場合に電流が流れ、LEDモジュール130が発光する。同様に、交流電源110の負の半周期においても、電圧の大きさがLEDモジュール130の順方向閾値電圧以上の場合に電流が流れ、LEDモジュール130が発光する。すなわち、図2に示すように、a区間とb区間で負荷電流が流れない。
従来技術にかかる双方向LEDモジュール装置は、印加される交流電源210と、抵抗R1を介して結合される双方向LEDモジュール220とを含む。
ここで、抵抗R1は、双方向LEDモジュール220に流れる電流の大きさを決定する。
