The communication unit 530 connects the control unit 700 and the illumination unit 500 wirelessly when the external power supply 200 is cut off and the cable is cut off and control of the engineer is impossible due to the occurrence of an emergency. At this time, the engineer can receive information such as the operating state and the lighting state of the illumination unit 500.

The emergency lighting switch 540 may be disposed outside the lighting unit 500 or near a seat where the passengers are seated so that the passengers can manually light the light emitting unit 510. [ Accordingly, when a problem occurs in the illumination unit 500 in an emergency state, the passengers can forcibly emit the light emission unit 510 by operating the emergency lighting switch 540. [

Therefore, the emergency lighting system 100 can be installed only by attaching it to the passenger room of the existing railway car, and can determine whether the passenger is present in the passenger room through the sensor unit 600 in the emergency state There is an advantage that emergency lighting can be provided to the passenger with low power.

Also, even when the external power supply 200 is shut off, power can be supplied through the battery unit 400 and the rechargeable battery 520,
