Measurement and analysis of disruptive glare UGR method by using luminance analyzer

The aim of this paper was to compare the results measured using the UGR method of computer programs and practical implementation. The reason for this comparison is newly deployed LED luminaires. For LED luminaires may happen some applications to the user´s subjective complaints of glare, although calculations for project documentation meet the conditions for glare reduction. The basic problem is a very small area from which the LEDs emit. The optical active area has significantly higher luminances than conventional light sources. The energetic advantage of lighting systems using LEDs will lead to more widespread usage, provided the lighting. It is therefore necessary that the issue involving high luminances in the direction of view of the user to solve as soon as possible.
