They are suitable for fixed lighting in coal mine tunnels and other places with explosive mixed gases such as methane and coal dust, as well as in gas or steam environments that do not damage insulation. Most existing mining tunnel lights have low heat dissipation efficiency, which makes them prone to failure due to slow heat dissipation, thus affecting their service life; although mining tunnel lights also have explosion-proof grade requirements, their explosion-proof performance needs to be improved.
