Abstract
An emergency light includes a lighting module configured for emitting lights, an input unit configured for receiving a power supply voltage from a home power supply, a normal driving module connected to the input unit to receive the power supply voltage and configured to output a first driving signal to drive the lighting module emit lights when the home power supply is normal; and an emergency control and battery module connected to the two input terminals and the lighting module. The emergency control and battery module is configured for detecting the alternating voltage of the input unit and a resistance value between the two input terminals to determine whether the home power supply failure occurs. When the home power supply failure occurs, the emergency control and battery module provides a second driving signal to drive the lighting module emit lights.
