The explosion-proof structure of the explosion-proof lamp, according to the size of the area and the explosive gas environment, if necessary, use the explosion-proof lamps and lanterns within the scope of Zone 1; the second fixture can be used for explosion-proof type and added safety, and portable lamps must be explosion-proof. The selection level or category of explosion-proof lamps should not be less than the explosion risk environment level and category of the mixture. LED explosion-proof lights. To consider the impact of the environment, explosion-proof lights should be satisfied with the ambient temperature, air humidity, corrosion or pollutants, such as various environments. According to different environmental requirements, choose the protection level and anti-corrosion type of lamps and lanterns. Especially in the corrosive gas in the explosive gas environment, it is very important to select the function of the corresponding anti-corrosion lamps.

In petrochemical enterprises, the main purpose of explosion-proof lighting for blasting risk sites. With the added safety type electrical equipment is widely used in blasting risk zone 2, the added safety and comprehensive lighting fixtures are also more and more used. Adding safety type lamps must have explosion-proof function, according to the comparison with explosion-proof lamps, light weight, low price, simple installation and protection, long service life, etc. In petrochemical enterprises, it is the most common use of complex electrical equipment safety - blasting compound, adding explosion-proof electrical equipment, generally composed of explosion-proof parts, adding safety terminals and adding safety shells. It is a combination of fire safety functions, but also Added the benefit of safe types.
