LED tunnel light is a kind of tunnel light, and it is widely used in the society. , billboards, landscaping lighting for building facades.

What are the characteristics of LED tunnel lights?

LED tunnel light is a kind of light-efficiency energy-saving lamp, using light-emitting diode (LED) as the light source, high light efficiency, long life, multi-purpose lighting with different mirror surfaces; and softening, causing glare or other discomfort. LED tunnel lamp ballast adopts overheating protection technology to ensure lamp life. Imported high-purity mirror-surface aluminum anodized material is used as the mirror surface and through precise light distribution design, the power factor is greater than 0.9, the reflection efficiency is high, and the light transmittance is good. The LED tunnel lamp is energy-saving and environmentally friendly. Comparison of LED and traditional tunnel lighting source LED is a solid-state semiconductor device, which can be directly converted into light. Compared with traditional road tunnel lighting (sodium lamp, metal halide lamp, etc.),

(1) Small light decay: if the heat dissipation conditions are good, the LED has positive light decay in the first 10,000 hours, 3% to 10% in the first 10,000 hours, and 30% in the first 50,000 hours, which is much lower than ordinary road lighting, and the light is more stable.

(2) High color rendering: Generally, the color rendering of LED is about 70~80, if you use tri-color phosphors, it will be higher; the general high pressure sodium lamp is 20~35, and the low pressure sodium lamp is lower, so even the brightness of the traditional light source is higher than that of the LED. High, but the visual effect is worse than that of LED, "not the brightest, but the clearest view"" This should be a direction for the development of LED light sources.

(3) Lifespan: LED lifespan is higher than that of general road tunnel lights, and now LED tunnel lights are generally higher than 50000H.

(4) Price: Although the current price of LED lamp head is higher than that of traditional lighting, with the maturity of manufacturing technology, the current price has dropped significantly. The general price of LED tunnel lamp high and low pressure sodium lamp is about 2,000 yuan, and its auxiliary pieces such as cables are expensive. The price is higher than the cost of LED cable.

In addition, LED also has the advantages of high maintenance factor, good safety, no flicker and energy saving. It is with this series of advantages that LED tunnel lights have been widely used in society.
