When a power failure accident occurs, the relay J1 is released, the normally closed contact J1-2 is closed, the super capacitors C3-C7 supply power to the light emitting diode LED3 and the LED4 flicker circuit, if the triode BG1 is firstly conducted, the collector voltage of the triode BG1 is reduced, the light emitting diode LED3 is lightened, the anode of the capacitor C8 is close to zero voltage, and the voltage at the two ends of the capacitor C8 cannot suddenly change, so that the base of the triode BG2 is also pulled to be close to zero voltage, the triode BG2 is cut off, and the light emitting diode LED4 is not lightened. The base voltage of the transistor BG2 is gradually increased along with the charging of the capacitor C8 by the power supply through the resistor R5, when the voltage exceeds 0.6V, the transistor BG2 is changed from an off state to an on state, the collector voltage is reduced, and the light-emitting diode LED4 is lighted.
