LUMINAIRE Russian patent published in 2018 - IPC A01G9/20 A01G7/04 F21V8/00 

FIELD: lighting.

SUBSTANCE: invention relates to the field of plant growing, in particular to lighting devices. Luminary contains a set of known light-emitting diodes with different emission spectra lying in the range of 400-800 nm, equipped with drivers. At the same time, light-emitting diodes with different spectra are selected from LEDs whose emission spectrum is in the range of 443-650 nm. Spectra of the selected LEDs overlap each other in different spectral regions of the range, preferably at 0.5 of the maximum amplitude. And used 5 types of LEDs with a power of 10W each, including warm white, blue, light blue; green and full spectrum. LED drivers are capable of delivering energy, which is respectively 1.4; 0.3; 0.3; 1.25 of the energy level fed to the full spectrum LED.

EFFECT: invention provides the luminaire with an emission spectrum corresponding to sunlight, while minimizing the total number of LEDs used.
