LED UNIVERSAL PHYTO-IRRADIATOR Russian patent published in 2021 - IPC A01G9/24 

FIELD: agriculture.

SUBSTANCE: invention can be used to irradiate vegetable and green agricultural crops at different stages of their growth in protected ground conditions, in phytotrons and industrial greenhouse complexes. The phyto-irradiator includes a group of LEDs with an adjustable radiation spectrum of each group and a control unit for the intensity and spectral composition of the radiation, which has a computer and a sensor. The phyto-irradiator has a body (1) which has a block of four groups of LEDs with an adjustable radiation spectrum of each line on it. The phyto-irradiator also has a protective screen against dust and moisture made of translucent thin-walled polycarbonate or glass and hermetically fixed on the body above the LED groups, a temperature sensor attached to the body and connected with a controller that monitors its temperature regime, and a heat removal system made in the form of a coil channel (6) which is threaded on the inner wall of the body, hermetically sealed with a lid and connected by tubes to a liquid cooling system.

EFFECT: invention enhances reliability of the phyto-irradiator operation, the smoothness of the regulation of the intensity and spectral composition of radiation to increase the yield and quality of products.
