摘要： 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.

摘要： An LED lamp and a power supply module thereof are provided. The power supply module includes a driving circuit, a OVP circuit, and an impedance detection circuit. The OVP circuit is configured to determine whether an OVP condition is detected by sampling the driving signal, and the impedance detection circuit is configured to determine whether a user touching state is detected. When either the OVP condition or the user touching state is detected, the power switch of the driving circuit will be controlled to limit the amount of a current flowing through the power switch. In addition, the impedance detection circuit could detect the user touching state by comparing signals with a defined level sampled during each pulse, thus enhancing the detection accuracy.
