Why is LED tunnel light most suitable for tunnel lightingAt present, the high pressure sodium lamp obtain a large-scale applications because of higher photopic luminous efficiency (up to 120lm / w) in lighting source adopting tunnel lighting, but it is still more difficult to overcome the main problem that is poor color and scope and limited choice of power source (usually only choose 250W and 400W) high pressure sodium lighting in the tunnel, especially in the interior section lighting, high pressure sodium has no less power, on the other hand, glare and flicker caused by strong punctate light is more serious. In some long tunnel, the straight tube fluorescent lamps because of its high color rendering and a good visual inducing linear light has also been a number of applications, but the life of the fluorescent lamp is short, usually only about 8,000 hours, and it often needs to be replaced, greatly increasing the maintenance cost of the tunnel. In addition, fluorescent less power can not meet the requirements at the entrance stage, transitional stage and outlet areas that require high illuminance. In recent years as the electrodeless lamp matures, due to the elimination the electrode factors, compared to traditional fluorescent lamp electrodeless fluorescent lamps have a longer life and more power, which makes the lamp reflected an advantage in the tunnel lighting applications. But lamp emitting surface is larger, when making optical designing,the optical efficiency is low. The LED tunnel light can be said is the integration of high-pressure sodium lamps, straight tube fluorescent lamp and various advantages. Just click to learn about more LED tunnel light. ...
