LIQUID-COOLED LED ILLUMINATOR Russian patent published in 2024 - IPC F21K99/00 F21V29/56 A01G9/20 

FIELD: lighting engineering.

SUBSTANCE: invention relates to LED lighting devices, and can be used for irradiation of vegetable and green crops at different stages of growth in conditions of protected ground, phytotrons and industrial greenhouses. Liquid-cooled LED illuminator comprises light-emitting diodes connected to power supply unit, placed on the profile and fixed inside a sealed transparent housing with plugs at the ends, filled with a transparent heat-conducting organosilicon anti-corrosion dielectric liquid, protective temperature sensor installed in the profile, which is connected to the power supply unit containing a potentiometer, and the aluminum profile with light-emitting diodes uniformly located along its entire surface. Profile is made in the form of a circular segment with a straight base in contact with the housing with a minimum gap, or a circular segment with a straight base and heat-removing ribs, or a circular segment with a trapezoidal base and heat-removing ribs, or in the form of a hollow polygonal profile, HDPE plugs are made with internal thread and with internal sealing rubber rings, at one end the plug is blind, and at the other end—with a sealed cable entry.

EFFECT: use of the irradiator will make it possible to expand its functional capabilities, increase energy efficiency, increase service life, brightness of lamps and their repairability.
