The topic of this final paper is the theory and application of artificial lighting and example of calculation. Artificial lighting is of great importance in our daily lives. Not only does it have a lighting function in times of poor visibility, but it improves safety and mood in people. Namely, the use of warm lighting can create a pleasant and peaceful atmosphere, while cold light stimulates mental and physical activity. Thus, it is clear that the requirements that lighting needs to meet for lighting, for example living rooms, are not the same as those needed in workspaces where lighting needs to provide adequate illumination of work surfaces in order to achieve work efficiency and thus better work results. At the beginning of the paper, I will talk in general about light and lighting as well as the advantages and disadvantages of natural and artificial lighting. Throughout the paper, I will list individual sources of artificial light and I will continue with light pollution as well as protection measures. At the end of the paper, I will explain, through an example, how to design and calculate artificial lighting.
