The daylighting and the artificial lighting is a part of environment. The lighting plays\nan important role in life of everyone of us. We know that it is not possible fully replace\ndaylighting by artificial lighting. The amount of daylight is important mainly in areas with\npermanent stay of people and it influences the choice of parameters and functions of system\nof artificial lighting.\nThat`s why I focus on the relations between daylighting and artificial lighting in my\nreport. Owing to these relations I evaluate influences causing an optimal using of artificial\nlighting. Finally, I state here the influence of using of lighting sources in lighting on\nenvironment and ecological aspects used for the production and the liquidation of light\nsources.
