Proposing a Method Reducing UGR Calculations for LED Luminaires with Diffusers in Indoor Applications

open access: yesApplied Sciences, 2022
This paper studies discomfort glare in indoor LED lighting systems and proposes a method reducing UGR calculations. There are several methods for expressing discomfort glare, among which the unified glare rating (UGR) method is one of the most popular ...

DISCOMFORT GLARE FROM DAYLIGHTING: INFLUENCE OF CULTURE ON DISCOMFORT GLARE PERCEPETION

open access: yesPROCEEDINGS OF THE CONFERENCE AT THE CIE MIDTERM MEETING 2017 23 – 25 OCTOBER 2017, JEJU, REPUBLIC OF KOREA, 2018
In a context where lighting standards are developed based on glare indices, no study has ever investigated that these indices could be used analogously for subjects having different cultures and living in different climates. The wide variability existing between individuals’ discomfort glare perceptions suggests, however, that some of the factors ...

Daylight Discomfort Glare Evaluation with Evalglare: Influence of Parameters and Methods on the Accuracy of Discomfort Glare Prediction

open access: yesBuildings, 2018
Nowadays, discomfort glare indices are frequently calculated by using evalglare. Due to the lack of knowledge on the implications of the methods and parameters of evalglare, the default settings are often used.

Stimulus Range Effect in Discomfort Glare Studies

open access: yesLight & Engineering, 2022
When asked for a subjective judgment, such as rating the discomfort from a glare source, the response of participants depends on the range of stimuli they are provided: this is known as a stimulus range effect.

Discomfort glare and time of day [PDF]

open access: yes, 2014
There are strong reasons to suspect that glare sensation varies with time of the day. This study was designed to test whether such a relationship exists. Thirty subjects were exposed to an artificial lighting source at four times of the day.

The Usefulness of Near-Field Goniophotometry Data to Assess Illuminances and Discomfort Glare in Indoor Lighting

open access: yesLEUKOS The Journal of the Illuminating Engineering Society of North America, 2021
In lighting simulations, a luminaire is usually modeled using a luminous intensity distribution emitted by a single-point source. This so-called far-field approach is valid as long as the dimensions of the luminaire are much smaller than the distance to ...
