Experimental Research on the LED Energy-saving Lighting and Controlling System in Highway Tunnel

应用LED节能灯替代高压钠灯进行隧道照明,采用减光棚、隧道内壁涂白等方式实施隧道引入段和过渡段的调光及增加隧道内部的亮度,并依靠可编程控制器和红外对射、噪声检测传感器组合对隧道全部LED照明灯具进行开启、关断自动控制。试验表明,应用LED节能照明自动控制系统完全满足隧道照明要求,比普通照明节能65%以上。

In this paper, A LED energy-saving bulb is applied to replace a high pressure sodium bulb in a tunnel. And then such ways as a light-reducing tent and smearing white on the inner walls of a tunnel and so on are used to adjust the light and increase the internal lightness in the tunnel beginning part and transition part. Meanwhile depends on the programmable logic controllers, the combination of mutual infrared lighting and noise-detecting sensors,automatically controlling of the turning on and turning off on all LED lighting bulbs is realized. The experiment indicates that the application of LED energy-saving lighting and automatically controlling system can completely meet the demands of tunnel lighting,and can save energy over 65 % comparing with an ordinary lighting.
