摘要
高速公路隧道照明系统的布灯参数决定着路面照度,影响着交通安全和照明能耗。为了得到高速公路隧道中间段中央布灯方式下最节能的布灯参数,以灯具安装高度、纵向安装间距和单灯功率为优化参数,以总功耗最小为目标,建立了隧道中间段中央布灯方式的参数优化模型。以九景高速公路雁列山隧道为例,通过优化模型得到该隧道中间段在中央布灯方式的优化布灯参数,并将优化结果与该隧道的布灯情况进行了比较。结果表明,基于优化布灯参数的LED灯照明系统,即使满负荷工作,比原高压钠灯照明系统节能超过51%,比改造后的电磁感应灯照明系统节能超过39%,节能效果显著;LED灯光衰30%以后路面照度及均匀度依然满足隧道照明要求。利用Dialux软件根据优化布灯参数建立了照明仿真系统并进行了仿真实验,仿真结果与优化计算结果基本一致,均满足隧道照明要求,证明了优化模型的正确性。
Lamp-installation-parameters（LIPs） of highway tunnel lighting system determine illuminance of road surface and influence traffic safety and lighting power consumption. In order to acquire the most energy-saving LIPs of central lamp distribution（CLD） lighting system in highway tunnel interior zone, the parameters optimization model（POM） of CLD for tunnel interior zone was established, with lamp installation height, longitudinal installation spacing and lamp power as optimization parameters, and with minimum total power consumption of the CLD lighting system as objective function. Yanlieshan Tunnel of Jiujing Highway was taken as the example for the optimization. The optimal LIPs of the CLD lighting system of the tunnel interior zone were obtained by the POM, and comparison between the optimization results and that of Yanlieshan Tunnel lighting system was performed, which showed that the optimized CLD lighting system with LED lamps installed based on the optimized LIPs could save more 51% electric energy than the original lighting system installed with high pressure sodium lamps and could save more 39% electric energy than the transformed lighting system installed with electromagnetic induction lamps even under full-capacity lighting condition, the energy-saving effect is remarkable. Illuminance and illuminance uniformity of the tunnel road surface still met the lighting demands even the LED lamp＇s luminance decreased 30%. A CLD lighting simulation experiment with the optimized CLD LIPs for Yanlieshan Tunnel was accomplished in the software Dialux, and the simulated results were obtained and met the lighting demands and basically agreed with the optimization calculation results, which proved the correctness of the CLD POM.
