Možnosti řízení světelných zdrojů v průmyslovém prostředí

Abstract

The thesis deals with the light sources. The theoretical part of thesis present and characterized most commonly used light sources, theories about what the light is, what was his development of the applications for the people needs. Further is presented the frequency converter, his functions principle, a basic parts, the history of the construction of oscillators applicable to the frequency converters. The practical part introduces the own construction of the frequency converter, used parts and evaluate the implementation of experiment - measuring light intensity when using different lighting sources operating on the principle of electrical discharge current at different supply voltage frequencies. Hypothesis in the thesis is confirmed and clarified.
