Abstract
It is known that in the case of technology use of the supplementary lighting, an irradiation spectral composition heavily influences the effectiveness of the photosynthesis processes, development and productivity of vegetable crops. Hence, the definition of general points at development and projecting of modern phyto-irradiators is one of high-priority tasks in techniques development for plants growing in conditions of protected ground. The research is aimed at reviewing and assessing the effectiveness of existing sources of illumination used in modern systems of supplementary lighting and at deduction of general points of development and projecting of phyto-irradiators based on results of laboratory investigations with the use of modern digital technologies of monitoring and data analysis. The results of the comparative tests of light emitting diodes-based phyto-irradiators showed that the energy consumption per product kilogram is less than in the case of LED-irradiators. Based on the research results, general points were deducted for use at development of modern LED-phyto-irradiators.
