Abstract
To reduce the enormous waste of electric energy in tunnel lighting, an intelligent control system of road tunnel lighting which can realize the effect of illumination moving with the vehicle is proposed. In this system, the group control of LED lamps is realized based on Air Lamp lighting technology through the wide area fusion Internet of Things (WF-IoT). By the group control of LED lamps, the tunnel lighting is divided into several illumination segments. When the vehicle is detected by the surveillance camera, the corresponding LED group can be adjusted to the demand luminance according to the environmental conditions and traffic information. The other LED groups maintain 10% of the maximum luminance to reduce energy consumption. To realize the effect of illumination moving with the vehicle, the structure of the intelligent control system and hardware system is designed, and the length of the illumination segment is calculated. To evaluate the lighting effect of the intelligent control system, a simulation model of tunnel lighting is established. In addition, the energy-saving effect of the intelligent control system is evaluated. The results show that the intelligent control system can meet the requirements of illumination in a tunnel and have a notable energy-saving effect.

Summary
The construction scale and quantity of tunnel engineering is increasing rapidly [1]. At present, the cumulative construction mileage of long road tunnels in China has exceeded 69% of the total tunnel mileage [2,3,4]. Li et al [12] proposed an energy-saving control system for a road tunnel which can adjust the luminance of the LED lamps to the maximum when a vehicle is detected by the vehicle. Considering its advantages, such as its long distance, consumption, WF-IoT is a mature product is the best choice forlow tunnel lighting control systems. Lamp intelligent new technology developed in the Air Lamp commercial IoT lighting networking protocol. The Air andID, dimming controller usedcontrol as the luminaires in tunnel lighting, andLamp each lighting technology is used to realize the group controlcontrol of the luminaires, which can achieve faster and LED lamp has its own ID, which enables the precise of luminaires. Lighting technology is used to realize the group control of to thelight luminaires, can achieve faster and more precise luminance control, and enable the luminaires to light up group by group
