摘　　要：为解决隧道照明系统中存在的能源浪费问题,基于无级控制方法设计了一种隧道照明自动控制系统。控制系统主要由车流量采集器、车速采集器、亮度采集器、数据转换器、照明控制计算机、驱动电源和配套的LED隧道灯组成,控制计算机收集各采集器的数据,按照调光控制逻辑和隧道照明控制模型调整洞内LED灯的功率,实现隧道洞内照明亮度的连续调节。对隧道照明控制模型进行了仿真试验,仿真试验数据和理论计算结果的误差小于2%,表明自动控制系统能够满足隧道照明的实际亮度需求。与按最大亮度值考虑的HPS灯和LED灯相比,无级控制的LED灯可分别节能80%和35%以上,比4级控制的LED灯节能20%以上。To solve the problem of energy dissipation in tunnel lighting system,an automatic control system fortunnel lighting is designed based on stepless control method.The control system is made up of vehicle detec-tors,luminance detectors,data converters,lighting control computer,dimming controllers and LED（light-emitting diode）lamps.The lighting control computer collects data from the detectors and adjusts thepower of interior LED lamps according to dimming logic and tunnel lighting control model to achieve continu-ous tuning of tunnel lighting luminance.The simulation experiment for the tunnel lighting control model isdone,comparison between simulation luminance data and theoretical luminance data calculated shows that theautomatic control system can meet the actual luminance requirements in tunnel lighting,the error can be controlled less than 2% .The stepless controlled LED lamps can save more than 80% and 35% energy than HPS（high pressure sodium）lamps and LED lamps respectively while they are used with maximum lighting value,and can save more than 20% energy than 4-step controlled LED lamps.
