Claims (2)
- 外部の商用電源から供給される交流電力を所定の電圧の直流電力である駆動電力に変換し、LEDに一定電流を供給してLEDの輝度を一定に保持する定電流制御用の駆動ICに上記駆動電力を供給すると共に、上記商用電源からの電力によってバックアップ電源を充電すると共に、商用電源が停電した際に、バックアップ電源に充電した電力を上記駆動ICに供給して、LEDの点灯を継続するLED照明装置において、上記駆動ICは電圧値によってLEDに供給する電流値を変化させるアジャスト端子を有しており、停電が生じていない状態では上記駆動電力の電圧値を分圧してアジャスト端子に入力し、停電が発生した状態では、上記バックアップ電源の電圧を分圧してアジャスト端子に入力させることを特徴とするLED照明装置。
- 上記バックアップ電源はコンデンサで構成されていることを特徴とする請求項1に記載のLED照明装置。
