ABSTRACT:
A strobo device in accordance with the present invention is provided with an insulated gate bipolar transistor connected to a flash discharge tube in series and a step-up capacitor to step up a voltage between the main electrodes of the flash discharge tube in the luminous operation. The step-up capacitor is connected so that a terminal on the side connected to a cathode of the flash discharge tube can have a high potential and the step-up capacitor is also connected so as to be charged by a current flowing through the flash discharge tube, which is not flashing. Thus the device realizes a rapid charging of the step-up capacitor. In this way a high voltage, at least more than twice as high as the charged voltage of the main capacitor, can be applied between the main electrodes of the flash discharge tube in the luminous operation, resulting in preventing flash failures during the repeating high-speed luminous emissions.
