Study on the Influence of Wall Reflection Coefficient on the Lighting Energy Saving of Operating Highway Tunnels Based on DIAlux
In order to quantitatively analyze the actual effect,energy-saving rate,and economy of the wall reflection coefficient on the energy-saving of operating highway tunnel lighting,the DIALux lighting calculation software was used to simulate the lighting environment of the entire section of the highway tunnel.The lighting conditions inside the tunnel were simulated under 9 different reflection coefficients(0.1～0.9),and a total of 180 working conditions were simulated using 20 example tunnels to study the impact of the wall reflection coefficient on the lighting effect of the road surface inside the tunnel.Energy efficiency analysis is obtained by reducing lighting configuration,and economic analysis is conducted using static investment payback periods.
