The abnormal protection of the electronic ignitor, in the conventional electronic ignitor circuit two ends of the resistor divider branch access delay circuits. When the lighting circuit is abnormal, the bulb end of the pressure was maintained in the power grid voltage exceeds the set time, the metal oxide semiconductor field effect transistor, is not enough to trigger diode, electronic trigger stop working. The main advantage of this utility model is a abnormal state protection after power lamp does not start, stop triggering within 5 minutes, to avoid long-term trigger for light bulbs, mh hps ballasts and high-voltage shocks ignitor itself, affect life expectancy, but also to avoid long-term electrical equipment near strong electromagnetic interference....
