Emergency lighting is an important safety facility in modern public buildings and industrial buildings. It is closely related to personal safety and building safety. When a fire or other disaster occurs in a building and the power is interrupted, emergency lighting plays an important role in personnel evacuation, fire rescue work, and the continued operation of important production and work or necessary operations.

[0003] At present, the leakage detection device of the fire emergency lighting circuit in the prior art usually contacts the circuit with a sensing device or a test pen for detection.
