The regional level and scope of the explosive gas environment are determined. For example, explosion-proof luminaires must be used in the range. The fixed luminaires can be explosion-proof and increased in safety, the mobile luminaires must be explosion-proof. The level or group of Explosion Proof Energy-Efficient Led Light selected should not be lower than the level and group of explosive mixtures in an explosive atmosphere. At the same time, the impact of the environment on the explosion-proof lamp should be considered, and the requirements of various environments such as ambient temperature, air humidity, corrosion or polluting substances should be met. The degree of protection and corrosion resistance of the luminaire should be selected according to different environmental requirements. Especially in the presence of corrosive gases in explosive atmospheres, it is important to choose a luminaire with appropriate corrosion protection.
In petrochemical enterprises, lighting fixtures in explosive hazardous areas mainly use explosion-proof type. With the widespread use of increased safety electrical equipment in explosive hazardous locations, increased safety and composite lighting fixtures are increasingly being used. Compared with the explosion-proof luminaire, the ampere-type luminaire has the advantages of light weight, low price, convenient installation and maintenance, and long service life.
