LED tunnel light is a kind of tunnel light. It is used in large-area flood lighting in tunnels, workshops, large warehouses, venues, metallurgy and various factories, engineering construction and other places. It is suitable for urban landscapes, billboards, building facades For landscaping lighting.

Advantages of LED tunnel lights:
Comparison of LED tunnel lights and traditional tunnel lighting sources LED is a solid-state semiconductor device, which can directly convert electricity into light. Compared with traditional road tunnel lighting sources (sodium lamps, metal halide lamps, etc.), LED light sources have the following advantages:

(1) Small light decay: if the heat dissipation conditions are good, the first 10000h of the LED is positive light decay, the first 10000h light decay is 3% to 10%, and the first 50000h is basically 30%, which is far lower than ordinary road lighting sources. Glow is more stable.

(2) High color rendering: Generally, the color rendering of LED is about 70-80, and it is higher if three primary color phosphors are used; the general high-pressure sodium lamp is 20-35, and the low-pressure sodium lamp is lower, so even the brightness of traditional light source It is higher than LED, but the visual effect is worse than that of LED. "Not the brightest, but the clearest view" should be a direction for the development of LED light source applications.

(3) Lifespan: The lifespan of LEDs is higher than that of general road tunnel lighting sources, and is now generally higher than 50000H.

(4) Price: Although the current price of LED lamp caps is higher than that of traditional lighting fixtures, with the maturity of manufacturing technology, its price is currently falling sharply. The price of a set of high and low pressure sodium lamps is generally around 2,000 yuan, while its cables and other auxiliary The price of the parts is higher than the cost of the LED cable.

In addition, LED also has the advantages of high maintenance factor, good safety performance, no flicker, energy saving and environmental protection.
