Identify safety lights and explosion-proof lights General safety lights and explosion-proof lights look very similar. Some industrial and mining enterprises often mistakenly put safety lights as explosion-proof lights in explosive areas, which is very dangerous. Although the general safety lamp is also equipped with glass lampshade and seal, but only waterproof, dustproof, but can not stop the flammable gas drilling, such as reaching the explosion limit will cause an explosion. The main difference between the two is the explosion-proof lights on the explosion-proof electrical certificate number. Lamp shell and cast with explosion-proof signs, but the general safety lights are not these features and signs. LED explosion-proof lamp is what LED explosion-proof lights mainly in high-power LED lamp beads and package integrated chip-based, combined with the light structure and the application of places such as the requirements to customize, but the choice of LED explosion-proof lights is the need to be cautious, especially the choice of power size and lighting is stress The size of the lamp power LED lamp shell size is closely integrated, because the high temperature LED lamps, high power lamps naturally require a larger shell to achieve good cooling effect. What is the characteristics of LED mining explosion-proof lamp for explosion-proof lamps and lanterns for coal mine lighting with gas or (and) coal dust explosion danger. The underground mine lighting has used incandescent lamps, fluorescent lamps, energy-saving lamps three times. LED as the fourth generation of new light source, with high luminous efficiency, low power consumption, long life, safety and reliability, environmental protection and other characteristics. LED has been widely used in coal mine safety production, and played an irreplaceable use, LED mining explosion-proof lights have been popular. Due to the many advantages of LED light source, it will also have broad application prospects in coal mines. It plays an important role in energy saving, safety production and coal mining cost reduction in coal mines.
