ABSTRACT:
An electric flash device for photography is controlled of its light radiation of a flash tube by a transistor, which is connected in series with the flash tube and is given its base current through a parallelly connected capacitor and resistor, and when the transistor turns OFF, an electric charge stored in the capacitor is applied across the base and the emitter of the transistor as a reverse bias.
