Purpose - to develop and manufacture experimental samples of LED phytolighting systems for plants with the ability to change the intensity and spectral composition of radiation. Research methods - modern methods of studying the electrical and statistical parameters and characteristics of energy-saving LED phytolighting systems with adjustable spectral composition were used in the work. As a result of the work, experimental samples of energy-saving LED phytolighting systems were developed and manufactured. The experimental samples of energy-saving LED phytolighting systems meet the requirements of the technical task and provided: rated power of more than 200 W; luminous flux fluctuations - no more than 2%; power factor - not less than 0.97; total efficiency of auxiliary electronic devices - not less than 78%; the ability to change the spectral composition of radiation according to certain algorithms; intensity of photosynthetically active radiation flux up to 500 μmol/s; photosynthetic radiation efficiency of up to 2.5 μmol/J; the ability to provide a photosynthetic photon flux density of at least 1250 μmol/(m2·s).
