With the rapid development of the petroleum, chemical, mining and other industries, lighting fixtures used in the production, storage, rescue and more widely, more and more varieties . In places where hazardous explosive gas lighting how to prevent accidental explosions have become a very important topic .
Since lighting inevitably spark formation at work or hot surfaces , once with explosive gas mixtures are produced or rescue scene of the encounter , it will lead to explosion occurred directly endanger the safety of life and property of the citizens of the country .
Therefore, as the most widely used lighting, explosion-proof technical problems it had aroused widespread concern and attention. Aluminum shell, surface spray ; lighting, emergency dual ; inner nickel -cadmium battery pack is automatically charged at the normal power supply , power failure or power outage accident emergency lights turn on automatically ; tube wiring ; emergency lights normally dedicated lighting and emergency lighting independently ; dual-lamp emergency lighting , normal lighting and emergency lighting public a light body , light independently.
LED explosion proof lights means for flammable gases and dust present in dangerous places , to prevent arcing , sparks and heat generated inside the lamp may ignite surrounding combustible gas and dust in order to achieve the required proof lamps . Flammable gas mixtures of different environments and explosion proof grade form of proof LED lights have different requirements .
Divided according to the type of protection flameproof , increased safety , positive pressure , no sparks and dust explosion-proof type of five main types , and also by other types of protection , and a combination of these various types of protection and special -shaped or complex type .
The most commonly used : flameproof is to take measures to allow an internal explosion and prevent flame proof type booster , this type of proof lamp housing is generally used metal materials , good heat dissipation , high strength and durability shell .
LED explosion proof lights Scope
1 . Suitable for explosive gas atmospheres 1 and Zone 2 hazardous locations ; 2 . Suitable for IIA, IIB, IIC explosive gas atmospheres level ; 3. Suitable for combustible dust Zone 20 , Zone 21 , Zone 22 ; 4. Suitable for temperature class T1-T6 environment.
