Abstract

The utility model discloses a xenon-mercury lamp trigger, comprising a starting switch, a first transformer, an energy storage capacitor, a second transformer, and a spark gap electrically connected in sequence. The starting switch is used to access electric supply to the xenon-mercury lamp trigger.

The energy storage capacitor is used to store electric energy and release the electric energy through the second transformer and the spark gap, and at the same time when the electric energy is released, transient high voltage is generated in the second transformer. The second transformer is used to boost the transient high voltage to second voltage which is supplied to a xenon-mercury lamp. Beneficial effects of the xenon-mercury lamp trigger are that magnetic core length of the second transformer is prolonged and the number of turns of a secondary coil is increased, so that trigger voltage of the trigger is improved, and the xenon-mercury lamp is easy to illuminate. The trigger is simple in circuit structure, relatively low in cost, and has relatively high reliability and work stability.
