ABSTRACT:
A flashing device comprises a rechargeable power supply, a voltage-raising circuit for producing a high voltage from an output voltage of the power supply, a condenser for storing the high voltage, a light-emitting tube for emitting light for a short moment using energy stored in the condenser, an emission control circuit for triggering light emission of the light-emitting tube, a charging circuit including a diode for allowing a current flow from the condenser to the power supply, and a changeover switch for discharging over connection of the power supply to the voltage-raising circuit or to the charging circuit.
