- 放電灯を点灯する放電灯点灯回路において、
電源電圧を受け、該電源電圧を昇圧して交流変換し、前記放電灯に交流電力を供給する昇圧交流コンバータと、
前記放電灯が起動すると、定常点灯時の周波数より長い周期の長周期信号を前記昇圧交流コンバータへ送出し、その後、前記定常点灯時の周波数である定常駆動信号を前記昇圧交流コンバータへ送出するものであり、前記長周期信号の周期を、前記電源電圧及び消灯時間により設定する制御回路とを備え、
前記制御回路は、前記長周期信号の周期を、前記電源電圧が低くなるほど長く、また、前記消灯時間が長くなるほど長く設定する
ことを特徴とする放電灯点灯回路。 - 前記制御回路は、
前記長周期信号の周期を、更に回路温度により設定し、前記回路温度が高くなるほど長く設定する
ことを特徴とする請求項1に記載の放電灯点灯回路。 - 前記制御回路は、
前記長周期信号の周期を、離散的に設定する
ことを特徴とする請求項1に記載の放電灯点灯回路。
