Glare is one of the most important parameter of lighting quality. Despite the passage of time from the beginning of glare research, no standard of conducting laboratory experiments was proposed. In the article the review of solutions related to glare assessment is presented. The method of conducting research on glare is also described. The authors pay attention to the most important aspects in the methodology of glare assessment for the experimental research on glare and glare assessment based on UGR measurements. The tests of the new algorithm for UGR calculation is presented-algorithm for precise identification and extraction of glare source area from HDR image. Streszczenie. Olśnienie jest jednym z najważniejszych parametrów jakości oświetlenia. Pomimo upływu czasu od rozpoczęcia badań nad olśnieniem, nie zaproponowano żadnego standardu prowadzenia eksperymentów laboratoryjnych. W artykule przedstawiono przegląd rozwiązań związanych z oceną olśnienia. Została także opisana metoda prowadzenia badań nad olśnieniem. Autorzy zwracają uwagę na najważniejsze aspekty metodyki oceny olśnienia w badaniach eksperymentalnych nad olśnieniem oraz metodyki oceny olśnienia w oparciu o pomiar UGR. Przedstawiono testy nowego algorytmu wyznaczania wskaźnika UGR; algorytmu precyzyjnego wyodrębniania obszaru źródła olśnienia na obrazie HDR. (Ocena olśnienia dla badań i rozwoju metod pomiarowych).

In this paper, the design of a luminaire for badminton court illumination is demonstrated from concept through computer simulation, construction trials, on-site installation, comparison with simulations and, finally, evaluations of the illuminated environment before and after the installation of the luminaires. The luminaire is composed of two high-performance light-emitting diode lighting modules, volume scattering diffusers with a one-shot transmittance higher than 70% and a reflecting cavity with a reflectivity higher than 85%. The luminaire has three different exit faces forming three Lambertian-like light sources with low luminance so as to reduce glare to the players when looking at the flight of the shuttlecock. Under similar total electric power consumption, compared to the original traditional lighting, the average illuminance on the ground is enhanced by about 300% and the uniformity is obviously improved. A questionnaire was issued to players before and after the installation of the new light-emitting diode luminaires. The new installation gained much more positive responses for brightness, comfort and number of usable courts from the players than the old installation.
