以交通隧道安全舒适行车和灯光照明节能为目标,分析了标准的交通隧道照明亮度曲线模型,仿真分析了隧道外亮度、车流量、车速等参数对隧道灯光照明功率损耗的影响。提出了隧道灯光照明节能减排的方法和按需照明的智能控制系统设计方案。研究表明,降低隧道入口处亮度、按需照明以及LED照明是降低隧道电能损耗的有效方法。 With the goal of traffic safety and traffic lighting and lighting energy saving, a standard traffic light curve model of traffic tunnel is analyzed. The influence of tunnel brightness, traffic flow, vehicle speed and other parameters on power loss of tunnel lighting is simulated. Put forward the tunnel lighting lighting energy saving methods and on-demand lighting intelligent control system design. Research shows that reducing tunnel entrance brightness, on-demand lighting and LED lighting is an effective way to reduce tunnel power loss.
