一种快速准确测量照明空间统一眩光指数的方法

A Fast and Accurate Method for Measuring Lighting Space UGR

现有的眩光测量方法不能明确找出照明空间最大统一眩光值(UGR)的所在点,所测得的UGR值也不一定是该空间的最大值,而且测量工作较为繁杂。为了快速准确地测得照明空间的UGR值,本文提出先用Dialux evo软件仿真计算,依据仿真计算结果设置UGR测点,再来测量UGR的方法,并在暗室中对该方法进行了实验验证。从实验结果来看,该方法不仅可以减少需设置的测点数、减少繁杂的测量工作,而且能求得被测空间最大UGR值。

Existing glare measurement methods can not clearly identify the point where the maximum UGR of illumination space is located,and the measured UGR value is not necessarily the maximum value of the space,and the measurement work is complicated.In order to quickly and accurately measure the UGR value of illumination space,this paper proposes a method to set UGR measurement point first and then measure UGR by using Dialux evo software simulation,and then validates the method in darkroom.The experimental results show that this method can not only reduce the number of measurement points to be set,reduce the cumbersome measurement work,but also obtain the maximum UGR value of the measured space.
