Tunnel lights are special lamps used for tunnel lighting in order to solve the "black hole effect" or white hole effect" caused by the sudden change of brightness when vehicles enter or exit the tunnel. The light source is generally used: sodium lamp, metal halide lamp and sometimes Use electrodeless lights. Tunnels are special sections of highways. When vehicles are entering, passing and exiting the tunnels, a series of visual problems will occur. In order to adapt to visual changes, additional electro-optical lighting is required.

With the rapid development of road traffic construction in my country, the construction scale and number of road tunnels have also become larger and larger, and tunnel lighting has also emerged such as energy saving and safety. As the LED light source technology has matured, the domestic lighting industry has also developed Based on the research and application practice of LED application in highway tunnel lighting, it will become a demand and trend to combine advanced control methods in tunnel lighting and adopt a new generation of light sources with high luminous efficiency, good stability and long life.

LED tunnel light is a kind of light-efficiency energy-saving lamps. Light-emitting diodes (LED) are used as the light source of the luminous body. It has high light efficiency and long life. With different reflectors, it can achieve multi-purpose lighting; Dazzling or other discomfort. The ballast uses overheating protection technology to ensure the service life of the lamp. Imported high-purity mirror-surface aluminum anodized material is used as the reflector and through the precise light distribution design, the power factor is greater than 0.9. The reflective efficiency is high, the light transmission is good, and it is energy-saving and environmentally friendly.
Road tunnel lighting has its own characteristics, it is not only the same as ordinary road lighting. The following points should be considered in the design: 1. The road surface should have a certain level of brightness. 2. The tunnel wall should have a certain level of brightness. 3. The design speed, traffic volume, route and many other influencing factors 4. From the safety of driving Comprehensively determine the lighting level 5, human vision, especially in the entrance section and exit section of the tunnel 6, and the tunnel also needs lighting during the day, and the lighting problem during the day is more complicated than at night.
In recent years, with the continuous update and development of LED chips, packaging and lighting accessories technology, the efficiency of LED light sources has increased to a new level. For example, the Spark series LED tunnel lights use high-quality chips, reasonable light distribution and structural design, and average light The efficiency is much higher than the current LED tunnel light products.
Scope of application: tunnels, workshops, large warehouses, gas stations, venues, metallurgy and various factories, engineering construction and other places.
