Let There Be Light? Impact of Light Pollution on the Environment
Svoboda, Lukáš ; Mihai, Hana (oponent) ; Ellederová, Eva (vedoucí práce)
Light pollution is one of many types of pollution that threaten our planet. The main reason for its creation is the fact that light pollution is a side effect of industrial civilization. The adverse effects of light pollution can have a serious impact on human health, wildlife and climate. The aim of this bachelor’s thesis is to define the concept of light pollution, describe means of its measurement and its adverse effects. The theoretical part of this thesis deals with defining what the light pollution is and it describes how it is manifested. Furthermore, possibilities of how light pollution can be measured are discussed. Subsequently, impacts on human health, wildlife, economy, safety, and astronomy are described and discussed. Towards the end, common light sources used for public lighting and their parameters are defined. Lastly, basic practices that help to reduce light pollution are presented with examples of correctly designed luminaires for outdoor lighting. The practical part of the thesis is concerned with quantitative research, whose purpose was to identify the level of awareness of light pollution among the general public. The data were gathered by means of the questionnaire survey.

Slovak standards and regulations for design and evaluation of indoor daylight in residential buildings require average values of the Daylight Factor (D) in two check points as basic criterion. In offices, the daylighting is evaluated in workplaces which can be often situated far from window. In this paper are presented results of daylighting measurements in deeper positions in three model rooms with different internal coloured surfaces which are exposed only to natural daylight during cloudy days. Positions are investigated from point of view of visual and biological response performance, represented by circadian efficiency, which may be significantly influenced by indoor surface’s colour selection.
