UGR stands for Unified Glare Rating. It is an objective measure of glare that is used by lighting designers to help control the risk that occupants of a building will experience glare from the artificial lighting. UGR values range from 40 (extremely high glare) to 5 (very low glare).

為了協助設計師更有效地控制眩光，國際照明委員會（CIE）提出了室內照明燈具統一眩光指數（Unified Glare Rating，UGR），以衡量照明設備對視覺舒適性的影響。

UGR stands for ‘Unified Glare Rating’ and is a method for assessing the glare effect of indoor lighting systems. It evaluates ‘psychological’, i.e. disturbing glare, but where there is no reduction in visual performance. The calculation method only provides meaningful results for mainly direct distribution luminaires.

What is UGR? Unified Glare Rating (UGR) is a measure of potential discomfort glare experienced by an occupant in interior lighting spaces. UGR incorporates data from electric sources within an interior environment and assigns a value which represents the calculated glare rating. It only accounts for sources for which IES file data is included.

2021年7月10日 · 统一眩光等级 (ugr) 是用于测量照明眩光造成的不适感的量表。它量化照明设备的眩光，考虑亮度、角度和光源相对于观察者的排列等因素。ugr 值通常在 10 到 30 之间，值越低越好。高 ugr 表示眩光严重，而低 ugr 表示照明舒适并减少视觉不适。

What is the Unified Glare Rating? The Unified Glare Rating (UGR) predicts the glare caused by an electric lighting system along a psychometric scale of discomfort. In simpler words, UGR predicts the amount of discomfort-causing glare produced by a lighting installation for a fixed set of conditions. Discomfort glare

Unified Glare Rating (UGR) is a standardized method for evaluating the level of discomfort glare that a luminaire can cause in a space. Developed by the International Commission on Illumination (CIE), the UGR scale ranges from 10 to 30, where lower values indicate a lower likelihood of glare, and higher values indicate a higher likelihood of ...

2023年7月25日 · The unified glare rating system measures direct light to predict “distraction levels” in a room. It averages the light values over surfaces like walls and work desks. Meeting these requirements ensures efficient lighting applications.

2025年2月20日 · A Unified Glare Rating (UGR) is a way designers can assign a value to the amount of glare likely to be experienced in an environment based on information about the luminaires, the room, and the likely position of observers. ... A light with a small origin point has a greater luminous flux or perceived brightness than one where the same ...
