摘要
为了解决LED光源应用于机动车交通道路照明时无测试标准可依的问题,参考现行国家标准GB/T 5700—2008《照明测量方法》提出了机动车交通道路LED路灯照明的照度和亮度测量方法,在照度和亮度指标之外提出了对小目标发现距离的指标,并探索了发现距离的测量方法。实测结果显示,发现距离可以直接用于评价照明效果对行车安全的影响,在进行照明效果评价时可以作为照度和亮度指标的补充。
No standard can be used to test the lighting quality of LEDs in road lighting,in order to evaluate the lighting quality of LEDs,we advanced illuminance and luminance measurement methods of LEDs used in road lighting,based on Measurement Methods for Lighting（GB/T 5700-2008）.We advanced another index beside illuminance and luminance,discovery distance,we advance measurement methods of discovery distance also.Measurement results indicates that discovery distance can be used to evaluate the influence of lighting quality to traffic safety,and discovery distance can be used as another index beside illuminance and luminance in road lighting.
