With the rapidly development of highway traffic construction, the number of tunnel light in highway has been steadily on the increase. Thereby, tunnel lighting has many urgent issues that must be solved, such as energy saving, safety, etc. Due to the mature gradually of LED light source technology, lighting industry has started to use LED in highway tunnel. Practice proves that using new generation light source has become the trend of times in tunnel lighting.

LED Tunnel Light, which selects lighting emitting diode as the luminophor of light source, is high efficiency and energy saving fixture. Its lifetime is long and it is able to realize many kinds of lighting when matched with different retroreflector. Meanwhile, after soften handled, it won’t make people feel dazzling or other unsuitable reaction. The ballast chooses the technology of thermal overheat protection to ensure the longevity of fixture.

LED is a solid semiconductor device, which has the ability to convert electricity into light. In contrast with traditional road tunnel light source, LED Tunnel Light has the following advantage.

1. Small lumens depreciation

In the condition of good heat dissipation, the first 10000h is positive lumens depreciation, which is about 3%10%. The first 50000h is about 30%, which is far lower than ordinary road lighting source and the shine is much more stable.

2. High color rendering index

In general, the color rendering index of LED is about 7080. When use trichromatic phosphor, it is much higher. On the contrary, the index of high pressure sodium lamp is about 2030. Therefore, even though the luminance of traditional light source is higher than LED, the visual effect is worse than LED.

3. Lifetime

The lifetime of LED is always over 50000h, which is far higher than ordinary road tunnel light source.

In addition, LED features on low maintenance, good performance, no strobe and environmental protection. Even though the price is a little higher than other fixture, anyway, it is the best light that is worth purchasing in the market.
