Modelování chování velkých vertikálních světelných zdrojů z pohledu jejich vyzařování do horního poloprostoru

Abstract

This diploma thesis deals with the issue of generating obtrusive light by the vertical light sources. The main purpose of this work is to assess the emission of the light flux into the upper half-space, which is generated by a model of a billboard illuminated by various lighting systems. The theoretical part is divided into four chapters. The first chapter describes how the individual manifestations of disturbing light arise. Furthermore, the standards that define the limitation of interfering light are described there. The second chapter deals with the description of individual vertical light sources such as illuminated advertisements, billboards, architectural lighting, car headlights, and last but not least, windows and shop windows. The third chapter describes the properties of reflective and transmissive materials used in lighting technology and a description of optical laws. The fourth chapter describes the Building Design software, which can be used to model the emission of the light flux into the upper half-space from various light sources. The practical part is divided into two chapters. The fifth chapter is focused on the design of a billboard lighting model using various lighting systems and their evaluation in terms of radiation to the upper half-space. In the last sixth chapter, the radiation of individual billboard lighting systems is compared with the radiation of the light flux into the upper half-space, which is generated by public lighting.
