Study On Energy Saving Of Highway Tunnel Lighting

In order to achieve the goal of lighting energy saving under tunnel safety conditions,based on in-depth analysis of tunnel lighting quality influencing factors and evaluation indicators,based on the brightness,speed and traffic data outside the tunnel,a tunnel lighting blur based on L₂₀-N-V under safe driving conditions was proposed control method.In-depth analysis of the influence factors and evaluation indicators of highway tunnel lighting quality,using DIALux and Ecotect lighting software to simulate the highway tunnel lighting scene respectively,by comparing the two sides of the tunnel symmetry,two sides staggered,the center,and the center line sideways With regard to the influence of tunnel lighting quality and energy consumption,the lighting layout plan for each section of the tunnel was determined,and the tunnel lighting layout plan and parameters were optimized.A hybrid lighting combination lighting scheme was proposed.The DIALux software was used to simulate the combined lighting scheme of the mixed lamps.According to the illuminance,uniformity and related energy consumption of the tunnel pavement,the entrance 1,entrance 2,transition 1,exit 1,and exit 2 adopt the central lighting method of LED+electrodeless lamp,Transition2,the middle section adopts LED+electrodeless lamp staggered on both sides of the way to the optimal state.Based on the above research,a tunnel lighting fuzzy control model with brightness,speed and traffic volume outside the tunnel as input parameters and brightness inside the tunnel as the output parameter was established to achieve the satisfaction of changes in weather environment and traffic parameters.The goal of adjusting the brightness in the tunnel in real time while driving safely.Take the Nan’anzhuang Tunnel of Zhang Zhuo Expressway as an example,optimize its existing lighting scheme,collect the brightness,vehicle speed and traffic flow data outside the tunnel collected from 6 to 18 in the morning of the tunnel entrance,and use MATLAB to perform fuzzy control dimming Through comparative analysis of hierarchical dimming,maximum brightness lighting and fuzzy control dimming,it is found that tunnel lighting fuzzy control saves 21%of electrical energy than hierarchical dimming and 44%of electrical energy than maximum brightness lighting.Research shows that the energy-saving control method for highway tunnel lighting can better solve the problem of mutual restraint between safety and energy-saving,and can achieve on-demand lighting while ensuring driving safety.
