1. It is suitable for dangerous places in Zone 1 and Zone 2 of explosive gas environment; 2. 2. Applicable to IIA, IIB, IIC explosive gas environment; 3. Suitable for combustible dust environment 20, 21, 22; It is suitable for environments with temperature groups T1-T6.

With the rapid development of petroleum, chemical, mining and other industries, lighting fixtures are more and more widely used in production, storage, and rescue, and there are more and more varieties. How to prevent the accidental explosion of lighting fixtures in explosive gas dangerous places has become a very important issue. Since lighting fixtures inevitably generate electrical sparks or form hot surfaces during operation, once they meet the explosive gas mixture at the production or rescue site, it will lead to an explosion accident, directly endangering the lives of citizens and the safety of national property. Therefore, as the most widely used lighting fixture, its explosion-proof technology has already attracted widespread attention and great attention. Aluminum alloy shell with plastic spraying on the surface; dual use for lighting and emergency; built-in maintenance-free nickel-cadmium battery pack, which can be automatically charged under normal power supply, and the emergency light will be automatically lit by accidental power failure or power failure; steel pipe wiring; Lighting and emergency lighting are independent; emergency dual-purpose lighting, normal lighting and emergency lighting share one lamp body, and the light source is independent.
