Do you understand the LED tunnel light and its characteristics?
Dec 11, 2018

Led tunnel light is a kind of tunnel light. It is applied to large-area floodlighting in tunnels, workshops, large warehouses, venues, metallurgy and various types of factories and construction sites. It is most suitable for urban landscapes, billboards and buildings. The face is landscaping.

With the rapid development of road traffic construction in China, the scale and quantity of road tunnel construction is also growing, and tunnel lighting has emerged as problems such as energy conservation and safety. With the maturity of LED light source technology, domestic The lighting industry has also carried out research and application practice of LED in highway tunnel lighting. Therefore, combining advanced control methods in tunnel lighting, using a new generation of light source with high luminous efficiency, good stability and long life will become a demand. And trends.

Led tunnel light is a kind of light-efficiency energy-saving lamp. Light-emitting diode (LED) is used as the light source of the illuminant. It has high light efficiency and long life. It can be used for multi-purpose lighting with different mirrors. Produces glare or other uncomfortable reactions. The ballast uses overheat protection technology to ensure the service life of the lamp. Imported high-purity mirror aluminum anodized material as a mirror and through precise light distribution design, the power factor is greater than 0.9,

High reflective efficiency, good light transmission, energy saving and environmental protection.

LED vs. Traditional Tunnel Lighting Source LED is a solid-state semiconductor device that converts electricity directly into light. Compared to traditional road tunnel illumination sources (sodium lamps, metal halide lamps, etc.), LED sources have the following advantages:

(1) Low light decay: If the heat dissipation condition is good, the 10000h before 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 the ordinary road illumination source. The light is more stable.

(2) High color rendering: general LED color rendering is about 70 to 80, which is higher if using three primary color phosphors; general high pressure sodium lamps are 20 to 35, low pressure sodium lamps are lower, so even the brightness of traditional light sources Higher than LED, but the visual effect is worse than LED, "not the brightest, but the most clear" This should be a direction of LED light source application development.

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

(4) Price: Although the current price of LED lamp head is higher than that of traditional lighting fixtures, with the maturity of manufacturing technology, its price is currently dropping sharply. The price of high and low pressure sodium lamp is generally around 2,000 yuan, and its cable is auxiliary. The price of the piece is higher than the cost of the LED cable.

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