Abstract
PURPOSE:To forcedly turn off a switching means at the time of completing the luminance of a flash lamp by stopping start of a main DC power supply for a fixed time even when the value of an output current of the main DC power supply is above a holding current of a switching means (thyristor). CONSTITUTION:When a control signal generating means 10 receives a driving control signal responding to a detection signal from a detection means 9 and a trigger pulse supplied from a trigger pulse generating means 12, it sends out a stop control signal to the main DC power supply control means 11 for starting or stopping the main power supply 4 for longer fixed time than a turn-off time of a thyristor 6. Thereby, the luminance of the flash lamp 2 is going to be completed, the current flowing through the thyristor 6 is made less than a holding current so as to forcedly turn off the thyristor 6.
