SPATIAL-ANGULAR DISTRIBUTION OF LUMINANCE IN LIGHTING DESIGN OF LIGHTING SCENES
Abstract and keywords
Abstract (English):
The article deals with modeling the spatial-angular distribution of luminance (SADL) in lighting scenes based on the solution of the global lighting equation by local estimates of the Monte Carlo method. Based on the SADL, a new criterion for lighting quality is formulated, which, in contrast to the generally accepted UGR to date, does not take into account the point glare sources, but directly the continuous distribution of luminance. The proposed criterion is applied in the analysis of lighting at some stations of the Moscow metro, which shows its correlation with the feelings of real observers.

Keywords:
spatial-angular distribution of luminance, quality of illumination, global illumination
