ABSTRACT OF THE DISCLOSURE At least one electric pulse having a predetermined voltage which is higher than a switching voltage for a pnpn semiconductor device and a predetermined width is applied across the pnpn semiconductor device. The electric pulse width is set not to turn the pnpn semiconductor device on. Consequently, a predetermined amount of carriers are accumulated in the pnpn semiconductor device. In this circumstance, a trigger light is supplied to the pnpn semiconductor device to be turned on. As a result, an energy of the trigger light is largely decreased as compared to a conventional method.
