In the field of lighting technology, glare evaluation is one of the basic parameters of determining the quality of lighting systems. Disturbing glare is most often evaluated by UGR in internal systems. The UGR method is well described and verified for uniform glare sources. With the development of LED, non-uniform sources of glare become involved in the lighting system. Thus verification of UGR suitability for non-uniform sources is necessary and possibly modification of the method or replacement it by another more appropriate method is required. This diploma thesis focuses on evaluation methods of disturbing glare from luminaires with non-uniform radiation surface. For this purpose, the thesis includes glare analysis, methods of glare calculation and glare evaluation. Furthermore, the UGR analysis and modification for the calculation of disturbing glare from non-uniform glare sources are included. The practical part is concentrated on measurement of glare from uniform and non-uniform glare sources. For the purpose of evaluating the suitability of the measurement method, the subjective evaluation of glare from a statically significant sample is included in the thesis. |
