Product Features of LED Tunnel Lights!
With the rapid development of China's road traffic construction, the scale and quantity of highway tunnels are also increasing. Therefore, problems such as energy saving and safety urgently need to be solved in tunnel lighting. With the increasingly mature LED technology, the domestic lighting industry in China has conducted research and practical applications of LED in highway tunnel lighting. Therefore, combining advanced control methods in tunnel lighting and adopting new generation light sources with high light efficiency, good stability, and long lifespan will become a demand and trend.
LED tunnel lights are highly efficient and energy-saving lighting fixtures that use light-emitting diodes (LEDs) as light sources. They have high light efficiency and long lifespan, and can achieve multi-purpose lighting with different reflectors. After being softened, they will not cause dazzling or other uncomfortable reactions in people. The ballast uses overheat protection technology to ensure the service life of the lamp. The imported high-purity mirror aluminum anodized material is used as the reflector, and precise light distribution design is used. The power factor is greater than 0.9, with high reflection efficiency, good transmittance, and energy-saving and environment-friendly features.
Comparison between LED and traditional tunnel lighting sources. LED is a solid-state semiconductor device that can directly convert electricity into light. Compared with traditional road tunnel lighting sources (such as sodium lamps and metal halide lamps), LED light sources have the following advantages:
The light decay of LED tunnel lights is small:
If the heat dissipation conditions are good, the first 10,000 hours of LED are normal light decay, and the light decay is 3%-10% in the first 10,000 hours, and basically 30% in the first 50,000 hours, which is much lower than ordinary road illumination sources, and the light emission is more stable.
LED tunnel lights have high color rendering properties:
The color rendering properties of general LED are about 70 to 80, which is even higher when using tricolor fluorescent powder. The high-pressure sodium lamp is usually 20 to 35, and the low-pressure sodium lamp is even lower. Therefore, even if the brightness of traditional light sources is higher than LED, the visual effect is worse than LED. "Not the brightest, but the clearest to see" should be a direction for the application development of LED light sources.
The lifespan of LED tunnel lights:
The lifespan of LED tunnel lights is higher than that of general road tunnel lighting sources, which is now generally more than 50,000 hours.
The price of LED tunnel lights:
Although the price of LED tunnel light heads is currently higher than that of traditional lighting fixtures, with the maturity of manufacturing technology, their prices are continuously decreasing. The price of a set of high and low voltage sodium lamps is generally around 2000 yuan, while the cost of their cables and accessories is higher than that of LED cables and costs.
In addition, LED tunnel lights also have the advantages of high maintenance coefficient, good safety performance, no flicker, and energy-saving and environment-friendly features.
