Claims (2)
- 外部の商用電源から供給される電力によりLEDを発光させるLED照明器具であって、この商用電源からの電力により充電させる蓄電部を有し、停電時にはこの蓄電部に蓄電された電荷の電圧を昇圧してLEDの発光を継続させるものにおいて、上記LEDは複数個のLEDが直列に接続されており、これら複数のLEDの発光個数を減少することによって上記蓄電部に蓄電された電荷の消費速度を減少させ、停電時におけるLEDの発光の継続時間を延長させるマイコンを有し、停電時において、上記LED発光用に昇圧された電力を降圧コンバータでさらに降圧してマイコンの駆動用電力を生成することを特徴とするLED照明器具。
- 上記蓄電部は、電気二重層コンデンサであることを特徴とする請求項1に記載のLED照明器具。
