The coal mine is a special lighting place with no natural light exposure, and downhole work is more dependent on lighting. Traditional coal mine lighting fixtures (incandescent lamps,

 fluorescent lamps, high-pressure, sodium lamps, etc.)have poor light transmission, short lighting life, and many maintenance times.

The coal mine is a special lighting place with no natural light exposure, and downhole work is more dependent on lighting. Traditional coal mine lighting fixtures (incandescent lamps, fluorescent lamps, high-pressure sodium lamps, etc.) have poor light transmission, short lighting life, and many maintenance times.

Coal mine lighting is generally divided into ground factory lighting and downhole lighting. Underground lighting can be divided into portable lighting, roadway lighting, blasting cave lighting, onboard lighting, mining face lighting and so on. Due to the difference in downhole environment and usage requirements, LED mining lamps and lanterns are classified as flameproof, intrinsically safe, flameproof and intrinsically safe according to the series of "GB3836-2010 Explosive Environment" standards. According to "Coal Mine Safety Regulations", "Comprehensive standard for coal mine electromechanical equipment" and "international  explosion-proof electrical standards" and other provisions.

 

CESP developed LED explosion-proof miner's lamp, Explosion proof LED hand lamp, LED explosion-proof drop light, LED explosion-proof emergency sign light and various types of explosion-proof plugs applied in downhole lighting with following advantages:

The whole lamp has good sealing performance, heat resistance, shock resistance and vibration resistance.

With a variety of circuit protection, low effect in voltage.

High light efficiency, stable light source, large average illumination, and strong light penetration.

The LED light source has strong seismic resistance, safety, reliability, energy saving, long  lifespan, and saves labor and electricity costs.
