Abstract

This master thesis deals with the problem of plant illumination by artificial lighting. The theoretical part of the thesis defines and compares radiant, photometric and photosynthetic units and their application in plant illumination. The way plants react to electromagnetic radiation and its various "colour" spectra is also explained. The types of light sources, the parameters of growing chambers and typical applications of grow lights are also compared. In the practical part, light-emitting diodes are compared in terms of photosynthetic parameters and then used to generate the optimal emitted spectrum for plant needs. The aim of the work is to develop a methodology for determining an indicative design of a grow lighting system with a conversion factor to convert photometric parameters to photosynthetic ones. In the last part of the thesis, the design, implementation and measurement of an experimental cultivation lighting system for year-round cultivation of fresh vegetables at the point of use is described.
