A control circuit for a xenon search light is provided to turn on a xenon search light of a large capacity of about 150 watt by providing a high start voltage. A control circuit for a xenon search light includes a power switch(10), an oscillating unit(20), a voltage-boosting unit(30), a high voltage generation unit(40), and an ignitor(50). If the power switch(10) is turned on, the oscillator(20) outputs a current of a specific frequency. The voltage-boosting unit(30) is controlled by the oscillating unit(20), and promotes lighting of a xenon lamp(X1) by providing a boosted voltage of a positive electrode of the xenon lamp(X1). The high voltage generation unit(40) is controlled by the oscillating unit(20), and raises a low voltage provided through the power switch(10) to a high voltage. The ignitor(50) turns on the xenon lamp(X1) by raising the high voltage provided from the high voltage generation unit(40) to a predetermined voltage and providing the raised voltage to a negative electrode. |
