The invention discloses a corridor emergency lighting facility powered on in a smart piezoelectric mode. The corridor emergency lighting facility powered on in the smart piezoelectric mode is characterized in that a voltage detection module judges that building electricity transmission fails and intelligently turns on the emergency lighting facility; after a main circuit piezoelectric transduction structure converts the mechanical energy generated by walking loads into electric energy, electric signals are obtained through conversion with a two-stage energy voltage reduction type DC-DC conversion circuit and then sequentially transmitted into a voltage stabilizing and rectifying circuit to be subjected to voltage stabilizing and rectifying and into a transformation output circuit to be subjected to voltage regulation, and finally the electric energy is supplied to lighting lamps to be used. When the voltage detection module judges that electricity transmission returns to normal, a common circuit is closed through switching intelligently. The corridor emergency lighting facility powered on in the smart piezoelectric mode has the advantages that the corridor emergency lighting facility is provided when a circuit fails or a disaster occurs, can guide an escape route for pedestrians in a building, the visual field is widened, and the escape risk of people is reduced; starting and closing of the facility and turning on and off of the lamps are switched intelligently; and the mechanical energy generated by stepping of pedestrians is collected through smart piezoelectric materials and converted into electric energy instantly, and energy supply of the emergency lighting facility is effectively achieved.
