室内眩光测量准确性探究
Research on the Measurement Accuracy of Indoor Glare

眩光是一种能引起观察者辨别能力下降的光现象。量化表征眩光影响的指标称为眩光指标，眩光指标包含多个参数，眩光测量的过程就是获取这些参数的过程，因此，眩光指标的准确性由这些参数的准确性决定。本文从UGR的定义出发，得出UGR的误差分析方法，研究了各参数测量准确性与UGR准确性的关系，并结合实际测量中的两个问题，探讨了测量室内眩光的正确方法。
Glare is a light phenomenon that can weaken the observer’s ability to discern. The index that quantifies the impact of glare is called the glare index. The glare index contains multiple parame-ters. The process of glare measurement is the process of obtaining these parameters. Therefore, the accuracy of the glare index is determined by the accuracy of these parameters. Based on the definition of UGR, the method of the error analysis for UGR can be obtained. We show the rela-tionship between the measurement accuracy of the related parameters and the accuracy of UGR, and investigate the correct method of measuring indoor glare based on two problems in actual measurement.
