Tai'an City Electric Co., Ltd. opened at 104 State Road, followed by the development of the times, the development of energy-efficient products. Professional production of mine explosion-proof lights, mature technology. Scope and Purpose DGS12 / 127L (B) type flameproof LED roadway lights (the LED lights) are using the latest semiconductor materials and constant voltage constant current LED cold light source from the development. For hazardous mine have gas and coal dust explosion in available parking lots and mechanical caverns, substations, roadway transportation, pumping stations and other places for fixed lighting purposes. Lamps in accordance with GB3836-2010 "Electrical apparatus for explosive gas atmospheres", MT221-2005 "coal mine explosion-proof lighting" and other relevant standards of design, manufacture and testing. Features ● saving effect is obvious: the more ordinary incandescent brightness equivalent to 90%, compared with 70% energy-saving energy-saving lamps. ● Long life: light life of up to 50,000 hours, to solve the frequent replacement of ordinary light bulbs or underground tube problems, maintenance-free, safe to use. ● Wide operating voltage range: to work between the input voltage 80V-260V, and the brightness is not any change, effective solution to easily burn underground tube voltage fluctuation phenomenon. ● environmental protection: pollution, wireless perimeter and ultraviolet radiation, is a new generation of green lighting. ● LED light colors are red, green, white are three underground lighting can do, but also can use mine lights. ● The independent wiring cavity structure and unique thermal design, and obtained a patent, the structure is more reasonable, simple, easy installation and maintenance ● through scientific and technological achievements in Henan appraisal concluded: leading.
