室内照明统一眩光值(UGR)校准装置的研制

Establishment of Calibration Facility for Unified Glare Rating(UGR)in Interior Lighting

统一眩光值UGR是表征室内照明眩光程度高低和视觉舒适度的重要参数,在室内照明检测和照明设计中有着广泛应用。目前国内对于眩光测试仪的溯源方法一般只采用光亮度标准装置校准亮度值,而对于照明光源的亮度分布和几何位置信息都没有进行相关校准,造成眩光测量结果的失准和不统一。针对此问题,本文研制了一套统一眩光值UGR校准装置,介绍了装置原理和结构,并对其不确定度进行分析。该装置的研制对于保障眩光测量结果的准确统一,有效提升照明设计质量,保护视觉健康有着重要作用。

The unified glare rating UGR value is an important parameter to characterize the degree of glare and visual comfort of indoor lighting,which is widely used in indoor lighting detection and lighting design.At present,the tracing method of the glare tester in China only uses the brightness standard device to calibrate the brightness value,but there is no relevant calibration for the brightness distribution and geometric position information of the lighting source,resulting in the inaccuracy and inconsistency of the glare measurement results.In order to solve this problem,this paper developed a set of unified glare UGR calibration device,introduced the principle and structure of the device,and analyzed its uncertainty.The development of the device plays an important role in ensuring the accuracy and unity of the glare measurement results,effectively improving the lighting design quality and protecting the visual health.
