可调光LED在隧道照明工程中的应用

On Adjustable LED Applied in Tunnel Illumination Engineering

以河北省承德市石洞子沟隧道照明工程为例,根据JTJ 026.1—1999《公路隧道通风照明设计规范》的标准要求,采用可调光LED光源对其照明系统进行设计。详细介绍了灯具布置方案及无级调光控制系统原理。该工程现已投入使用,经过现场实测,隧道内照明完全达到国家要求的照度和均匀度,且与传统隧道灯具相比有效节约了电能。

Taking Shidongzigou tunnel illumination project in Chengde,Hebei for example,and according to the requirements ofJTJ 026.1 —1999 Design Specification for Ventilation & Illumination of Highway Tunnel,the related illumination system is adopting adjustable LED light source.Luminaries ’ layout plan and stepless adjustment light control system principle are introduced in detail.The project has been in service,and the illumination within the tunnel can arrive at luminance & uniformity requirements of national standards totally after a field surveying.What ’s more,it can save the power effectively compared with traditional tunnel luminaries.
