灯点灯回路。 For emergency lighting equipment that has a DC/AC switching function consisting of an AC relay and a capacitor and can turn on fluorescent lamps using either DC or AC power, a diode is connected in series with the discharge resistance of the capacitor to change the polarity when the DC power is supplied. A fluorescent lamp lighting circuit characterized in that even when reversely connected, DC power is prevented from being applied to an AC drive circuit without driving an AC relay.
