Flameproof the principle according to European standard EN13463-1: 2002 "Non-electrical equipment for explosive atmospheres - Part 1: Basic methods and requirements" concept explosion proof lights and fire type bad52, flameproof are allowed to take measures to prevent an internal explosion and a booster flame proof type, is the most commonly used type of protection. Since this type of proof lamp housing is generally used metal materials proof lights bcd200, heat resistance, high strength and durability shell, very popular with users. Moreover, many increased safety explosion-proof light fixture components, such as lamp holder, interlock switches, also used flameproof explosion-proof structure patented design led emergency lighting, by environmental 2200mah 3.7V lithium-ion battery; comply with the new national standards for explosion proof. By environmental 2200mah 3.7V lithium-ion battery powered emergency, when the main power fails bootable emergency lighting explosion-proof lighting immediately, can also be controlled via an external switch.
