The Tunnel is known as connecting the roads and railways, thanks to the tunnel , the car and the train can travel freely, especially in mountainous areas, the tunnel plays the much more important role in connecting the roads to bring convenience to our trip, so more and more mountain are opened up, meanwhile,we encounter another thorny problem, how to light it? The fluorescent light was firstly thought,although because fluorescent lamps are covered by the vitreous and are mainly designed for interior lighting, which simply is not only unable to adopt to the open-air environment that is full of the air and moisture, but also be easily damaged by the frequent shaking passing vehicles makes in the tunnel, , the theoretical 8000 hours life of the fluorescent is significantly reduced, but there is mercury and other heavy metals in phosphor fluorescent, once broken, it will do harm to our health and pollute the environment, moreover the efficiency of fluorescent light is low, which simply can not be used at the entry section, transition and outlet areas that require high illuminance environment. We continue to develop and improve other light, then the high-pressure sodium lamp was invented, but the high pressure sodium also has the vitreous shell, it can not very well qualified for the tunnel environment, but it is filled with high pressure sodium and mercury vapor, it will also pollute the environment, In order to overcome these two fatal flaw, we developed the energy saving LED tunnel light that is famous for the semiconductor lighting -, the shell of the LED tunnel light is made of high strength, good toughness alloy and environmentally friendly materials, the transparent pieces is the strengthened glass, which has the character of dustproof and waterproof, corrosion rust and is good at resisting he strong impact strength and impact; multi-channel vibration structure and high-tech surface coating, a variety of high-strength high-frequency close vibration can not make an impact on the lamps, and can steadily work in the workshop, roadbed, track and other high-frequency vibration and humidity high temperature environment for a long time. Good electromagnetic compatibility, will not interfere with the transmission network. Undoubtedly,the LED tunnel light is the best lighting in the tunnel. Although the LED tunnel light is more expensive compared to conventional fluorescent lamps and high pressure sodium lamps, but the late repair and maintenance cost savings can offset the extra purchased inputs of LED tunnel lights, log http://www.lead-lighting.com/products/bid32-1.htm to learn more about characteristics and parameters of the LED tunnel light.
