Claims (5)
- LEDランプを光源とする照明灯具において、前記照明灯具には、PWM制御を行う電源制御部と、タイマ回路と、遅延回路とが設けられ、前記照明灯具の点灯時には、前記遅延回路により前記LEDランプの規定の光度までの上昇が、所定の傾斜をもつ光度の上昇をもって行なわれ、前記照明灯具の消灯時には、前記タイマ回路が一定時間導通し電源制御部に電源を供給して前記遅延回路にPWM出力を行い、前記LEDランプの消灯までの光度の低下が、所定の傾斜を持つ光度の減少をもって行われることを特徴とする照明灯具。
- 前記照明灯具の消灯時の所定の傾斜は、消灯開始時から消灯完了時までの50%〜70%の時間内に傾斜量の変位点を有し、消灯開始点から変位点までの傾斜量に対し、変位点から消灯完了時までの傾斜量が略半分であることを特徴とする請求項1に記載の照明灯具。
- 前記変位点は、消灯開始時から消灯完了時までの略60%の時間に有することを特徴とする請求項2に記載の照明灯具。
- 前記消灯開始時間から消灯完了時間までの時間は、120〜200msであることを特徴とする請求項2または3に記載の照明灯具。
- 前記照明灯具は、テール/ストップランプを有する車両用であり、前記電源制御部とタイマ回路と遅延回路とはストップランプ側にのみ設けられていることを特徴とする請求項2〜4記載の照明灯具。
