Abstract

PURPOSE:To shorten a light emission waiting time and to emit light in plural light emitting modes by permitting a charge and discharge control means to control plural capacitors so that they begin to charge and are prohibited from charging with time lag. CONSTITUTION:The 1st and 2nd capacitors 24 and 12 supplying electric charges to a discharge tube 21 and the charge and discharge control means are provided. It controls the capacitors so that the first capacitor 24 begins to charge the 2nd one 12 when the capacitor 24 is charged to a 1st prescribed voltage or above. The control means prohibits the discharge of the 2nd capacitor until it is charged to a 2nd prescribed voltage. Therefore electric charges can be accumulated in the capacitors all the time. Thus the light emission waiting time of the titled flashing device is shorter than that of a conventional flashing device, and the former can emit light in plural light emitting modes.
