Emergency Lights To Secure Or Continue To Work

The role of emergency lights

Emergency lights are in the normal lighting system due to power failure, no longer provide normal lighting conditions, for evacuation, security or continue to work the lights. Emergency lights are different from ordinary lighting, which includes: spare lighting, evacuation lighting, safety lighting three.

Standby lighting should normally be set in the following locations:

(1) A place such as hydrogen production, paint production, chemical, petroleum, plastic, celluloid and its products for the production, production and solvent production of accidents such as explosion, fire and poisoning after the power failure is not carried out in a timely manner or disposal Some operating parts.

(2) after the power failure is not carried out in a timely manner or disposal will cause the production process confusion or processing of valuable parts of the damaged parts of the place. Such as chemical industry, some of the oil industry processes, metallurgical, aerospace and other industrial steelmaking furnaces, metal melting casting, heat treatment and precision machining workshops in certain sectors.

(3) places where the lighting is extinguished will cause a greater political or serious economic loss. Such as important communication centers, radio stations, television stations, power plants and central substations, control centers, national and international conference centers, important hotels, international terminals, transport hubs, important power supply stations (heating, gas supply , Oil supply) and water supply facilities.

(4) lighting extinguished will hinder the fire rescue work carried out by the place. Such as fire control room, emergency power room, radio room and power distribution room.

(5) Important underground buildings will not work and be active due to lighting extinguishment. Such as subway stations, underground hospitals, large and medium-sized underground shopping malls, underground hotels, underground restaurants, underground garage and underground entertainment.

(6) lighting extinguished will cause cash, valuables stolen place. Such as large and medium-sized shopping malls of valuables sales area, cashier and bank cashier and so on.

Emergency lighting system to own power independent control type, the normal power supply from the ordinary lighting power supply circuit, usually on the emergency light battery charging, when the normal power cut off, the backup power supply (battery) automatic power supply. This form of emergency lights each lamp has a transformer, voltage regulator, charge, inverter, battery and other large number of electronic components, emergency lights in the use, maintenance, failure when the battery charge and discharge. The other is centralized power centralized control type, emergency lights without independent power supply, the normal lighting power failure, by the centralized power supply system. In this form of emergency lighting system, all the internal electronic circuit is saved, the emergency lighting and ordinary lighting is no different, centralized power supply system set in a dedicated room.
