lights, portable emergency lights, fire emergency lights, LED
emergency lights, energy-saving emergency lights, explosion-proof
emergency lights, underwater emergency lights, rechargeable
emergency lights, solar emergency lights, multi-function emergency
lights. Among them, fire emergency lights are divided into: fire

2. Emergency light principle:
There are two sets of power supply systems inside the emergency
light. One set is the internal battery to supply the light. The
other set is the external power supply to supply the light while
charging the battery. In addition, there is a power conversion
mechanism. When the external power supply is disconnected
(blackout) The line will switch to the way the battery is powered.
This will keep the emergency light on while the emergency light is
off.
