ABSTRACT:
A flashlight emission apparatus is provided which inhibits the emission of flashlight from a flash discharge tube before a voltage to which a main discharge capacitor is charged reaches a proper voltage level for emission. This occurs in response to an output from a detector that detects the voltage across the main capacitor. The apparatus provides an indication that the main capacitor is being charged as long as the converter is in operation to provide a booster action, and terminates the indication and ceases the operation of the converter when the voltage across the main capacitor reaches a proper voltage level for emission.
