The circuit includes the AC voltage generator, transformer or transistor AC voltage converter, the power that the flash needs can be adjusted by the potentiometer Rp1 according to need. When the thyristor is blocked, the flash transformer discharges, the capacitor is charged by the 2.2MΩ resistor. When the potentiometer Rp2 smooth contactor voltage is lower than the little Ne pipe, the pipe is conducting, the thyristor is also conducting, so the 0.2μF capacitor discharges, the flashing transformer provides power for the flash pipe.
