通过隧道照明系统设计和控制模式的案例分析,提出了基于隧道洞外照度、行车速度、交通量及照明供电电压等因素的隧道照明节能控制方案,对现行高速公路隧道照明控制现状及其节能潜力进行浅析。分析发现,行车速度、交通量是隧道照明设计中两个极为重要的参数,直接影响隧道内照明度;通过安装变功率镇流器、照度仪、车辆检测器、车速检测器等技术手段,有效地调控隧道照明设施,解决了现行隧道照明设计中的缺陷。另外,从实际测试数据,可得同样的灯具及变功率镇流器,电压升高,功率消耗相差很大。
According to the case analysis of tunnel lighting system design and control mode, the tunnel lighting energy saving control scheme based on tunnel external illumination, traffic speed, traffic volume and lighting supply voltage is proposed. The current status of tunnel lighting control and its energy saving potential Analysis. The analysis shows that driving speed and traffic volume are two very important parameters in the tunnel lighting design and directly affect the illumination in the tunnel. Through the installation of variable power ballasts, illumination meters, vehicle detectors, vehicle speed detectors and other technical means, effective To regulate the tunnel lighting facilities to solve the design of the existing tunnel lighting defects. In addition, from the actual test data, available the same lamps and variable power ballasts, voltage, power consumption vary widely.
