Exploring the Applicability of the Unified Glare Rating for an Outdoor Non-Uniform Residential Luminaire

Abstract: The Unified Glare Rating (UGR) and the modified version (UGR’) have been developed and widely accepted in multiple standards for measuring the discomfort glare of a luminaire in typical indoor environments; however, a standardized glare metric for non-uniform outdoor luminaires is still missing. In this paper, the possibility to apply UGR and UGR’ to an outdoor residential luminaire with a non-uniform spatial luminance distribution is explored. The luminaire was characterized in a large near-field goniophotome… Show more

“…Lighting quality has a profound impact on occupant visual comfort and overall wellbeing. Parameters including illuminance, color rendering index (CRI), and glare index are key to evaluating lighting quality [22]. Adequate illuminance levels promote visual clarity, while CRI ensures accurate color perception.…”

“…Illuminance measurements can help ensure that the lighting levels are appropriate for the activities performed in each area [10]. Glare is a visual sensation caused by excessive brightness or contrast and can be assessed using tools such as the unified glare rating (UGR) [11]. By analyzing glare, designers can ensure that the lighting design does not cause discomfort or visual impairment.…”
