CONTROL METHOD FOR PULSED LIGHT DEVICE AND RELATED DEVICE

A pulsed light device and a related device are provided. The pulsed light device includes a charging module, a capacitor, and a light source. The capacitor is connected between the charging module and the light source, the charging module is configured to charge the capacitor, and the capacitor is configured to supply power to the light source to allow the light source to flash. The control method includes: controlling the light source to flash N times in one flash window, N being an integer greater than or equal to 3; controlling the capacitor to discharge to the light source during each flash of the light source; and controlling the charging module to charge the capacitor during a time interval between two adjacent flashes.
