But in the day-to-day inspection wefound that there are many problems in the process of selection, installation and use of fireemergency lighting unit. There should be a reasonable choice of the emergency lightingsystem power supply control mode, wiring, do well routine maintenance work, all these willplay a direct impact on the role of the fire emergency lighting system.Types of Emergency LightsThere are many kinds of emergency lights, according to different functions and structures,emergency lights can be divided into the following common types: led emergency lights,portable emergency lights, fire emergency lights, the energy emergency lights, supplyemergency lights, underwater emergency lights, rechargeable emergency lights, solaremergency lights, multi-function emergency lights.
