防爆燈具是否防水

Explosion-proof lights are not necessarily waterproof.

The principle of flameproof (enclosed) explosion-proof lights is to isolate the ignition source from explosive gases. Their casings are not completely sealed and have small gaps. These gaps play a crucial role in explosion prevention; as the 火焰 passes through these narrow spaces, it encounters resistance and heat dissipation, reducing the heat to levels insufficient to ignite explosives. For requirements that demand both explosion-proof and 防水 capabilities, ensure the casing’s protection rating is specified as IP65 or IP66.
