Tunnel lighting is different from general road lighting. It has obvious particularity and importance. It plays a vital role in the traffic safety of the tunnel. Therefore, when designing, it is necessary to consider the factors of human light adaptation and dark adaptation, and pay attention to excessive Design of space and excessive lighting. Tunnel lighting lamp source selection problem lamps are required to be able to operate normally in an environment where the relative air quality is relatively poor, the temperature is relatively low, and the light source is difficult to replace. The use of lamps should consider the light distribution control of the road cross section direction, so that the road surface and the wall can achieve efficient lighting at the same time. The types of light sources include gas discharge light sources, LED light sources, and electrodeless light sources. At the entrance and exit, use HID light sources such as low-pressure sodium lamps, high-pressure sodium lamps, and metal halide lamps. In basic lighting, the use of induction lamps is gradually increasing. At present, gas discharge lamps are commonly used in tunnels. Because LEDs and electrodeless lamps have significant effects on energy saving and environmental protection, there is a trend to replace gas discharge light sources, but the actual lighting effect needs to be tested.
With the development of modernization, the scale and quantity of tunnel lighting facilities will become larger and larger. Tunnels are places with high energy consumption, and electricity operating costs are getting higher and higher. There will be more urgent needs for effective energy-saving light sources, lighting energy-saving control systems, and reasonable brightness design to improve the lighting effect and ensure the stability and suitability of driving.
