PURPOSE: To provide a flat light emission driving circuit for a stroboscopic device by which the flat light emission of a stroboscope is realized stably in flat and smooth light emission wavelength. CONSTITUTION: A diode D4 preventing the rapid recharge of a trigger capacitor C1 is connected between the trigger capacitor C1 and the collector of a switching element IGBT1. By charging the trigger capacitor C1 through a resistance for charging R4, light emission is shifted to a series of flat light emission. After the trigger capacitor C1 discharges by turning on the IGBT1, the rapid recharge of the trigger capacitor C1 is prevented by the diode D4, and a trigger circuit consisting of the trigger capacitor C1 and a trigger coil T1 is prevented from continuously acting in the midst of the flat light emission, so that the influence of trigger noise is eliminated. |
