钱塘江隧道中间段LED照明系统评估研究

Study and Evaluation of the Lighting Performance of LED Luminaires for the Interior Zone of Qiantang River Tunnel

基于LED光源的优点,钱江隧道拟在其中间段采用LED照明,并将四款灯具(A、B、C、D)于现场试挂,评选出最好的LED隧道灯。在4308小时评估周期中,定时测量并记录路面测试网格的照度值。分析发现B灯具的照度衰减量最大,为4.6%;C灯具的照度衰减量最小,为1.9%。在评估过程中采用另一种照度计进行比较测试,以评价测量过程数据的稳定性。方差分析法(ANVOA)分析对比测量数据的结果表明照明环境、灯具光谱、测量人员等会影响照度的结果,且灯具A、D比灯具B、C的测量稳定性好。

Based on the advantages of LED lighting source, the tunnel lights of the interior zone of Qiantang River tunnel is planned to adopt LED lighting. And LED tunnel luminaires （A, B, C, and D） from four manufacturers were installed, and their performances are evaluated. With recording the illuminance data of each measurement point on the road for about 4308 hours, we found that luminare B has the highest illuminance degradation of 4.6% , whereas luminaire C has the lowest illuminance decay of 1.9%. In order to evaluate the measurement stability, we used another illuminometer to performe comparison test. ANVOA （analysis of variation） analysis result shows that the lighting environment, spectrum of the luminaire, testing stuff etc. , can influence the illumination results and luminaire A, D have better measurement stability than that of luminaire B and C.
