A controller is provided for several sets of flash lamps that shares a common power source. The controller comprises a high-voltage charging/discharging circuit and several sets of flashing circuits that shares the high-voltage charging/discharging circuit. The high-voltage charging/discharging circuit is a voltage-increasing loop. comprising two diodes, two capacitors, and a choke coil. Each flashing circuit is a self-activating flashing circuit comprising a resistive-capacitor charging circuit, an activating coil, a silicon controlled rectifier, and a flash lamp. Each set of flashing circuit includes a power source end that is electrically connected to an output end of the high-voltage charging/discharging circuit.
