LED PHYTO-ILLUMINATOR FOR TOMATO GROWING Russian patent published in 2019 - IPC F21K99/00 

FIELD: lighting engineering.

SUBSTANCE: invention relates to lighting engineering and can be used for illumination when growing tomato culture at all stages of its growth in phytotrons and industrial greenhouses. Technical result is achieved by the fact that in a light-emitting phyto-illuminator for tomato growing, comprising a housing with light-emitting elements, according to the invention, the light emitting elements consist of a combination of light-emitting diodes, the radiation spectrum and power of which are balanced and matched with the intensity of absorption and the role in photosynthesis of key pigments of the photosynthetic apparatus of the plant chlorophylls, carotinoids, cryptochromes, phytochromes, wherein the combination comprises five types of light-emitting diodes with emission band maximums within the range of blue 434–450 nm, red 630–632 nm and 660–670 nm and far-red 730–735 nm, wherein part of blue light-emitting diodes is combined with luminophore with maximum reradiation in green spectral region of 500–600 nm, and distribution of radiation power in spectral regions is blue 15–20 %, green 15–20 %, red 50–55 %, far red 10–15 %.

EFFECT: increased photosynthetic activity, reduced power consumption and simplified operation during cultivation of tomato culture; high efficiency of photosynthesis, increased food quality of tomato and reduced energy consumption of phyto-illuminator.
