Abstract
A control device of a flash type movable decorating lamp comprises a high voltage converting circuit, an actuating circuit, a high voltage storage capacitor, a flash displaying circuit and other units. The time difference between charging and discharging of the high voltage converting circuit to the high voltage storage capacitor and the voltage difference for the triggering of the flash lamp tubes are used to replaced a movable decorating lamp sequential control circuit. Part of the storage capacitor and each the flash lamp high voltage generating circuit are used in common so as to achieve the object of simplifying part of the circuit and the manufacturing process becomes more economic.
