By using the studies of highway tunnel as research background, a tunnel lighting energy-saving LED lamp control system is designed, which according to the requirements of highway tunnel lighting safety, comfort level and energy-saving. The system uses monitor computer as the operation control core, and median machine as the local output controller. By using CAN bus control, going through the sensor module to collect vehicle flow rate, the speed and the brightness information. Subsequently, the system input control parameters as the control signal output to the lighting equipments from the operation control center are collected. Therefore, the command to the microcontroller and control the real-time automatic switch to on-off state in the different sections of the tunnel lighting is implemented. Based on the development of the lightings intelligence control system of CAN bus technology, to improve the lighting scalable class, the control precision, and the lighting continuity. In the meantime, it also saves the electric energy of the operation system. This paper includes the diagram for the tunnel control system, the research on the structure of the control system, and the usage analysis of the features and requirements of the control system.

In order to acquire the most energy-saving luminaire installation parameters (LIPs) of highway tunnel interior zone, a parameters optimization model (POM) of symmetric luminaire distribution (SLD) lighting for tunnel interior zone was established. It includes luminaire installation height, longitudinal installation spacing, crosswise installation spacing, elevation angle and power as optimization parameters, and with minimum total power of the SLD lighting system as objective function. Yanlieshan tunnel of Jiujing highway was used as an example for the optimization. The optimal LIPs of the SLD lighting system of tunnel interior zone were obtained by the POM. A comparison between the optimization results and that of Yanlieshan tunnel lighting system is performed, which demonstrates that the optimized SLD lighting system with LED lamps installed according to the optimized LIPs has remarkable energy-saving effect even under full capacity lighting condition. Illuminance and illuminance uniformity of the tunnel road surface still meet the traffic lighting requirements. Even the LED lamps’ luminance decreases by 30%. A SLD lighting simulation experiment with the optimized SLD lighting LIPs for Yanlieshan tunnel was carried out by the software Dialux. The simulation results primarily agree with the optimization calculated results from the POM, which proves the correctness of the SLD lighting POM.
