LED tunnel lights are energy-saving lamps with light efficiency. They use light-emitting diodes (LEDs) as the light source. They have high light efficiency and long life. They can be used with different reflectors to achieve multi-purpose lighting. They are softened and will not cause discomfort to people. Dazzling or other uncomfortable reactions may occur. The ballast adopts overheating protection technology to ensure the service life of the lamp. Imported high-purity mirror aluminum anodized materials are used as reflectors and through accurate light distribution design, the power factor is greater than 0.9.
LED Tunnel Lights and Underpass Lighting Buying Guide
Comparison between LED tunnel lights 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 (sodium lamps, metal halide lamps, etc.), LED light sources have the following advantages:
1. Small light attenuation: If the heat dissipation conditions are good, the LED light attenuation is positive in the first 10000h, the light attenuation in the first 10000h is 3% to 10%, and the light attenuation in the first 50000h is basically 30%, which is far lower than that of ordinary road lighting sources. The light is more stable.
2. High color rendering: Generally, the color rendering of LED is about 70 to 80, and it is higher if three primary color phosphors are used; Generally, the color rendering of high pressure sodium lamp is 20 to 35, and the color rendering of low pressure sodium lamp is lower, so even if the brightness of traditional light sources is higher than that of LED , but the visual effect is worse than that of LED. It is not brighter, but it can be seen more clearly. This 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 50,000H.
4. Price: Although the current price of LED lamp heads is higher than that of traditional lighting fixtures, with the maturity of manufacturing technology, their prices are 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 parts is higher than the cost of LED cables.
In addition, LED also has the advantages of high maintenance factor, good safety performance, no flicker, energy saving and environmental protection.
