a) Power saving and high brightness: Comparing to the incandescent lamps with the same brightness, LED lamps can save 80% electricity. The effect is obvious. The brightness of 10W LED lamp corresponds to 60-80W old laneway lamp.b) Long life:As using LED light, it can come up to 50,000 hours. No need to replace the light source all the life to solve the problem of frequent replacement of old light bulb.c) Good security: As the Operation temperature of LED lights is low, lamps’ structure is reasonable, explosion, impact resistance, and high sealing performance, it is safe to use in the underground.Explosion-proof type: flameproof; proof mark: ExdIThe main basic parameters: Rated voltage: 127V power: 12WIllumination shall comply with the provisions of the table:NoNameIrradiation distance,mIllumination,lx1Laneway room lighting 3 >102Mining face lighting 2 >5Working pressure:Lamps should bear 2000v/1min frequency voltage, no breakdown, and flashover.Structure and working principleMainly the lamp is made of the aluminum lamp body, the power block, a number of high-power LED light tube, reflective bowl, transparent shade and other components.
