ELECTROMAGNETIC RADIATION SPECTRUM FORMING METHOD, AGRICULTURE LIGHTING METHOD AND AGRICULTURE LIGHTING SYSTEM Russian patent published in 2019 - IPC F21K99/00 F21S4/00 A01G7/00 

FIELD: lighting.

SUBSTANCE: invention relates to lighting engineering and is intended for illumination of plant crops. Said technical results are achieved due to the fact that the electromagnetic radiation spectrum formation method, which consists in improvement of plants irradiation efficiency and acceleration of their growth by forming a radiation spectrum using emitters with certain wavelengths of radiation wavelength, is carried out by mixing: a first type of emitter having a dominant emission wavelength of 434 to 446 nm and a relative intensity of 0.22 to 0.28, a second type of emitter having a dominant wavelength of radiation from 450 to 472 nm and a relative intensity of 0.22 to 0.28, a third type of emitter having a relative intensity of 0.08 to 0.12 in the wavelength range from 500 to 580 nm, a fourth type of emitter having a dominant emission wavelength of 614 to 626 nm and a relative intensity of 0.22 to 0.28, a fifth type of emitter having a dominant wavelength of 634 to 646 nm and a relative intensity of 0.65 to 0.75, a sixth type of emitter having a dominant wavelength of 654 to 666 nm and a relative intensity equal to 1, and a seventh type of emitter having a dominant wavelength of 734 nm to 746 nm and a relative intensity of 0.22 to 0.28. Variant of the agricultural crops lighting method is also described, where lighting is carried out in the first and second time periods by at least part of the above mentioned radiators, and a system for lighting the agricultural crop by using the above method.

EFFECT: technical results achieved at the same time are as follows: economy of electric energy consumption, faster development of agricultural crops and increase of crop capacity of agricultural crops.
