MH Tunnel light、HPS Tunnel light

in order to solve the vehicle into or out of the tunnel when the brightness mutations make visual effect of "black hole" or "white hole effect", used for tunnel lighting special tunnel lighting lamps and lanterns. Due to the special environment of lamps and lanterns and light source requirement is relatively high, the dongguan from lighting tunnel lamp shell with high strength, good toughness alloy environmental protection material, transparent to strengthen toughened glass, dustproof, waterproof, corrosion rust.Has the strong ability of the collision and impact resistance;Multi-channel shockproof structure and high-tech surface spray processing, all kinds of high strength high frequency vibrations from close range can't affect the lamps and lanterns, and in the workshop, roadbed and rail high-frequency vibration and damp, high temperature medium and long term stable working environment.Good electromagnetic compatibility, power transmission network will not cause interference.In the choice first consider light lights, light life, energy conservation and environmental protection etc;So now commonly used light source are: metal halide lamp, high-pressure sodium lamp, electrodeless lamp and other special point source.
