Flash device.

摘要

An improved flash device which is characterized in the provision of a power source, a main capacitor (C3) adapted to be charged by the power source, a flash firing unit operable to consume charge stored in the main capacitor to emit a flash light, a trigger circuit (3) for exciting the flash firing unit in response to a flash firing command, an insulated gate bipolar (IGBT) transistor disposed in a discharge loop for the main capacitor through the flash firing unit, and a control circuit (5) for applying a voltage to a gate of the insulated gate bipolar transistor in response to the flash firing command and for interrupting the application of the voltage to the insulated gate bipolar transistor in response to a flash terminating command.
