| Summary: | The cheap LED products with high overall brightness without sufficient protective angle lenses of luminaries or shielding the light-emitting elements can be sources of high glare and create discomfort or even glare the human eyes. For timely assessment of high-quality lighting performance, which is done visual work, in European standards regulated by a combined indicator of discomfort (in Ukrainian standards - a rating of discomfort), the experimental determination is not possible, and the existing engineering method of calculation which is enough complex and requires considerable time. The article presents the results of analysis of the Unified Glare Rating in the program for the calculation and modeling of lighting systems. The calculation model of parameter UGR has been considered. The influence of the input parameters on the final result of the calculation of the combined discomfort are analyzed. Оne of the main input parameters for the calculation of the UGR, taking into account its location relative to the line of view of the observer has been investigated. |
