摘要
路面的光学反射性能是决定道路照明质量的重要因素,其描述参数——路面简化亮度系数是道路照明计算中的重要参数,但长久以来我国使用的是国际照明委员会在20世纪70年代建立的标准C表,与我国实际路面材料和运行情况相差很大,从而造成道路照明的巨大浪费。目前市面上还没有可用于路面简化亮度系数实验室精确测量的商业仪器。本文主要介绍了一套由分布式光度计结合成像亮度计改造而成的实验室自动化测量系统,给出了测量原理和系统设计,测试了25块路面样本,部分测试结果与一套手动测试系统的测试结果进行了比对,结果表明两者的简化亮度系数值差异均在10%以内。
The optical reflection performance of the road surface is an important factor determining the quality of road lighting.Its descriptive parameters,the reduced luminance coefficients,are important parameters in the calculation of road lighting.However,for a long time,China has used the standard C table established by the CIE in the 1970s,which is significantly different from the actual pavement materials and operation conditions in China,resulting in a huge waste of road lighting.Currently,there are no commercially available instruments that can be used to accurately measure the reduced luminance coefficients of road surfaces in the laboratory.This article mainly introduces a set of laboratory automated measurement system that is transformed from a gonio-photometer combined with an imaging luminance meter.The measurement principle and system design are given.25 road samples were tested,and some of the test results were compared with the test results of a manual test system.The results showed that the differences in the reduced luminance coefficient values between the two systems were within 10%.
