Abstract

PURPOSE: To control the quantity of light through a relatively simple circuit by emitting impulsive light with constant intensity continuously.
CONSTITUTION: When the quantity of light attains to a preset specific value, that is detected by a detecting means and a main switching element is turned on and off by a means which turns on a switching element for commutation to generate a light emission stop signal for turning off the main switching element and a means which starts operating with said light emission stop signal to generate a light emission restart signal for turning on the switching element again after a specific time shorter than the deionization discharge tube 14 and also generates a speedy charge signal for turning on a switching element for speedy charging. Consequently, impulsive light emission with nearly constant intensity is carried on during the shutter exposing operation of a camera.
