With the rapid development of industries such as petroleum, chemical, and mining, the use of lighting fixtures in production, storage, and rescue is becoming increasingly widespread, with a growing variety. How to prevent accidental explosions of lighting fixtures in explosive gas hazardous areas has become a very important issue. Due to the inevitable generation of electric sparks or the formation of hot surfaces during the operation of lighting fixtures, once they come into contact with explosive gas mixtures at production or rescue sites, it can lead to explosion accidents, directly endangering national property and the safety of citizens' lives. Therefore, as the most widely used lighting fixture, its explosion-proof technology has already attracted widespread attention and high attention from people.
Traditional explosion-proof lamps are usually produced by professional explosion-proof lamp manufacturers, mainly using explosion-proof technology. With the rapid development of new light sources such as LED, explosion-proof lamps using new light sources have begun to apply explosion-proof technologies such as intrinsic safety, increased safety, n-type, as well as a combination of multiple technologies. More and more ordinary lighting manufacturers are entering the field of explosion-proof lighting production.
As the name suggests, explosion-proof lamps refer to explosion-proof lamps used in explosive environments.
From a product perspective, explosion-proof lamps are divided into:
1. Mining explosion-proof lighting fixtures: explosion-proof lighting fixtures used in coal mines, belonging to Class I.
2. Non mining explosion-proof lighting fixtures.
(1) Used in explosive gas environments outside of coal mines, it belongs to Class II.
(2) Used in non coal mine dust explosion environments, belonging to Class III.
Market access system for explosion-proof lamps in China
1. Mining explosion-proof lighting fixtures, used in coal mines and non coal mine underground areas, require obtaining the National Coal Mine Safety Mark Certificate, also known as the Coal Safety Certificate.
2. Non mining explosion-proof lamps are mainly used in non mining explosive gas environments and combustible dust environments, and require obtaining an explosion-proof certificate.
3. On October 1, 2019, the State Administration for Market Regulation announced that some explosion-proof electrical products would be included in the national mandatory product certification catalog, but there were no explosion-proof lamps. This means that the current market access system for explosion-proof lighting fixtures in China only requires obtaining an explosion-proof certificate.
4. According to the latest announcement on May 1, 2024, explosion-proof lamps and control devices have been officially included in the national mandatory product certification catalog, namely the explosion-proof CCC certification.
