摘要： In the disclosed flash system, a flash voltage detector operates a switch which enables a flash triggering circuit only after the flash voltage reaches a predetermined value. In a preferred embodiment the switch includes a unidirectional element in series opposition to the triggering current flow. When the flash voltage is sufficiently high the switch passes forward current through the unidirectional element thereby decreasing the voltage drop thereacross and permits a triggering current.
