R1,R2:抵抗
C:タイマーコンデンサ
Claims (3)
- 放電灯と、該放電灯に制御された電力を供給する電力制御装置と、を備えた車両用放電灯を点灯するとき、該電力制御装置が、該放電灯に起動電力を付与して点灯開始し、その後、該起動電力より電力の低い定常電力まで電力を低下する車両用放電灯の制御方法であって、
電力の低下の開始から該放電灯の温度が付与される電力の変化によりラジオノイズを発生するようになる温度に低下するまでは第一の低下速度で、その後は、該第一の低下速度よりも遅い速度の第二の低下速度の低下速度で該起動電力から該定常電力まで電力が低下したときに、該放電灯の温度低下の温度勾配が所定以下となるように行われることを特徴とする車両用放電灯の制御方法。 - 前記電力制御装置は、前記第一の低下速度の時の電力を供給する第一の電源と、前記第二の低下速度の時の電力を供給する第二の電源と、前記第一の電源からの電力あるいは前記第二の電源からの電力を前記放電灯に供給する電力供給部と、該電力供給部に供給される電力を該第一の電源と該第二の電源との間で切り替える電源選択部と、を備えた請求項1記載の車両用放電灯の制御方法。
- 前記電源選択部は、前記第一の電源からの入力に基づいて切り替えを行うタイマーコンデンサをもつ請求項2記載の車両用放電灯の制御方法。
