摘　　要：作为建筑照明系统验收和绿色建筑评价的重要考量因素之一,统一眩光值的重要性不言而喻。阐述了统一眩光值检测的研究现状,在实际检测中,立体角传统测量方法为先测量观察者与灯具相对位置尺寸,再通过公式近似计算结果,存在立体角测量误差较大的问题。基于三维建模测量立体角的方法,对某办公室系统的统一眩光值进行了实测,并将眩光源立体角计算公式法和三维建模法两种立体角测量方法的检测结果进行对比分析,得到三维建模法检测更准确的结论,以期提高统一眩光值检测的准确度。As one of the important considerations in the acceptance of building lighting system and green building evaluation,the importance of unified glare rating is self-evident.The research status of UGR detection is described.In the actual detection,the traditional measurement method of three-dimensional angle first measures the relative position size of the observer and the luminaire,and then approximates the result by the formula,which has the problem of large error in the measurement of the three-dimensional angle.Based on the method of three-dimensional modelling to measure the stereo angle,the UGR of an office system was measured in practice,and the detection results of the two stereo angle measurement methods,namely the formula method of calculating the stereo angle of the glare source and the three-dimensional modelling method,were compared and analysed,and a conclusion was drawn that the detection of the three-dimensional modelling method was more accurate,with a view to improving the accuracy of the detection of the UGR.
