Modeling of luminous flux radiation to the upper hemisphere from real model of town

Popis výsledku v původním jazyce

Article targets to show potential of software goniophotometer from point of view calculation of the luminous flux leads to the upper hemisphere from road lighting system. Basis for this article was real model of blocks of flats in Frydek-Mistek. Software goniophotometer was originally checked in terms of accuracy for calculation direct and reflected part of the luminous flux [1]. In next step was creating of basic model formed from several objects including buildings and road lighting system realized by five luminaires [2]. Software upgrade allows possibility of inserting calculation grid in sphere shape. These points represented normal illuminance in direction to the middle of sphere and behave like an imagine luxmeter sensors. Aim of implementation this net is update simulation program for calculation of the luminous flux radiated to the upper hemisphere from artificial lighting systems as basis for next astronomic calculation which are deeply focused on night sky luminance description [3]. Using this model will possible to do models of the artificial light radiation of whole towns contains not only road light systems, but other artificial light sources too. Principle is to include radiation characteristics of these big units to LDT file as a one luminaire with information about luminous flux and shape of luminous intensity distribution. This LDT file could be used for next calculations which will evaluate influence of big light sources to night sky luminance. (C) 2019 IEEE.
