プ発光装置。[Claims for Utility Model Registration] The device comprises a flash lamp, a main capacitor that supplies luminous energy to the flash lamp, and a charging circuit that charges the main capacitor, and the charging circuit is configured to charge the main capacitor. A voltage detector detects the charging voltage, and generates an output signal that compares the detection signal from this voltage detector with a reference voltage signal to constantize the charging voltage of the main capacitor to a set value corresponding to the reference voltage signal. a control circuit that controls the charging operation based on the output signal from the charging voltage comparison circuit; and a control circuit that generates a digital signal corresponding to the detection signal from the optical sensor that detects the light of the flash lamp. a light amount signal generation circuit that generates a light amount signal, a light amount control circuit that generates a level shift signal when the digital signal from this light amount signal generation circuit is smaller than a preset light amount reference value, and a light amount control circuit that generates a level shift signal based on the level shift signal from this light amount control circuit. 1. A flash lamp light emitting device for exposure, comprising: a reference voltage adjustment circuit that shifts the level of a reference voltage signal of the charging voltage comparison circuit to increase a set value of the charging voltage of the main capacitor.
