采用LED节能灯泡代替隧道内高压钠灯泡，采用减光帐篷、隧道内壁涂白等方式调节光线，增加隧道起始部和过渡部的内部亮度，同时依靠可编程逻辑控制器，结合红外照明和噪声检测传感器，自动控制所有LED灯泡的开、关。实验表明，LED节能照明及自动控制系统的应用完全可以满足隧道照明的要求，与普通照明相比，可节能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.
