公路隧道入口和过渡段照明布灯参数优化研究

Study on Luminaire-Distribution Parameters Optimization for Threshold and Transition Zone Lighting of Highway Tunnel

为了得到高速公路隧道入口段和过渡段两侧对称布灯方式下的最优布灯参数,以总功耗最小为目标,以路面照度满足照明要求为约束条件,建立隧道入口段和过渡段两侧对称布灯方式下的参数优化模型。以九景高速公路雁列山隧道为例,通过优化模型求出布灯优化参数以及总功率,与该隧道的实际布灯情况进行了比较。结果表明,采用优化布灯参数的LED隧道灯照明系统,装灯总功率比该隧道的电磁感应灯方案的装灯总功率减少69.59%。利用DIALux软件对雁列山隧道的优化布灯参数进行仿真实验,验证优化模型的正确性。优化亮度适应曲线与理论亮度适应曲线的比较表明,优化的布灯方案同样能较好地满足视觉适应要求。

To obtain the optimal luminaire-distribution parameters（LDPs） of highway tunnel threshold and transition zone lighting system with symmetrical luminaire-distribution-style（LDS）, a parameter optimization model（POM） of SLDS for tunnel threshold and transition zone was established, by taking illuminance of road surface meeting lighting requirement as constraint conditions, and taking minimum total power consumption of the lighting system as the objective function. In this paper, Yanlieshan tunnel of Jiujing highway was taken as an example for the optimization. The optimal LDPs and the corresponding total power of the lighting system were obtained by the POM, and a comparison analysis between the optimization results and that of the real tunnel lighting system was performed. The research results show that the total power of the LED lighting system installed according to the optimized LDPs was less 69.59% than the total power of the transformed lighting system installed with electromagnetic induction？lamps. A simulation experiment of the optimized LDPs of Yanlieshan tunnel lighting system was carried out by using Dialux software and the simulation results verified the correctness of the POM. The comparison between the optimized brightness adaptation curve and the theoretical brightness adaptation curve of the highway tunnel indicates that the optimized LDS can meet the visual adaptation requirement preferably.
