Function and composition of emergency led lighting
Emergency led lighting is a type of lamps that can effectively illuminate and display evacuation passages when the normal lighting power supply fails, or can continue to illuminate and work uninterrupted. Widely used in public places and places where lighting cannot be interrupted.
Emergency led lighting is composed of light source, light source driver, rectifier, inverter, battery pack, sign lamp housing and other parts. Usually, 36V drives the light source for normal lighting through the light source driver, and supplements the battery pack with power through the rectifier. Even when the lighting is turned off after get off work, the rectifier still works in a charging state, so that the battery pack is always in full combat readiness. . When encountering an emergency and the city power suddenly stops, the inverter will automatically start the inverter circuit, convert the low-voltage power of the battery pack into high-voltage power, and drive the light source to continue lighting.
Evacuation emergency led lighting and sign lights, collectively referred to as fire emergency lighting, are an important product required in fire safety measures. Usually it needs to provide lighting like ordinary lamps. When there is an emergency, such as an earthquake, fire or circuit failure, the power supply is suddenly interrupted, and all light sources have stopped working. At this time, it must provide reliable lighting immediately and indicate the evacuation of people. Directions and location of emergency exits to ensure smooth evacuation of people stranded in the dark. It can be seen that emergency lighting is a light source that keeps lighting and guides evacuation in emergency situations.
