基于布灯参数优化的隧道照明节能控制

Tunnel Lighting Energy-saving Control Based on Parameter Optimization of Luminaire Distribution

为了保证在行车安全的前提下最大程度地降低隧道照明能耗,提出了一种针对隧道中间段的照明节能控制系统。该系统以布灯参数优化后的照明系统为基础,根据实际车速、车流量确定隧道最小需求亮度,采用调光控制方法调节LED灯的功率,实现照明节能。以雁列山隧道为例,对参数优化后的中央布灯照明系统进行节能控制,并与只进行优化的照明系统和该隧道实际改造后的照明系统进行比较,结果表明,实行调光控制的照明系统比只进行优化的照明系统至少节能38.8%,比实际改造后的电磁感应灯照明系统至少节能63.1%,节能效果非常显著。利用Dialux对实行调光控制的照明系统进行了仿真,仿真结果表明,不同车速、车流量条件下的隧道路面最小照度、路面照度总均匀度和路面纵向照度均匀度均满足交通要求。

In order to reduce the energy consumption of tunnel lighting to the greatest degree on the premise of guaranteeing driving safety, a lighting energy-saving control system for the tunnel interior zone was proposed.Based on the optimized luminaire-installation-parameters（LIPs）, the lighting system was controlled to realize the maximum energy-saving by using dimming method to adjust the power of LED lamps according to the minimum demand brightness determined by the actual vehicle speed and vehicle volume. By taking the tunnel-interior-zone lighting system of Yanlieshan tunnel as an example, the energy-saving control of the optimized central luminaire distribution lighting was carried out, and contrasting experiments were conducted between the LIPs optimized lighting system and the actual transformed lighting system with electromagnetic induction lamps（EILs）.The results found that the dimming-controlled lighting system can save 38.8% more energy than the optimized lighting system without control, or save 63.1% more energy than the actual transformed lighting system with EILs, and the energy-saving effect was remarkable. The dimming-controlled lighting system based on the optimized LIPs was simulated with Dialux. The simulation results showed that the minimum illuminance, overall uniformity and longitudinal uniformity of the tunnel road surface illuminance meet the traffic demands of the tunnel lighting.
