LIGHT DIODE RADIATOR FOR PLANT GROWING Russian patent published in 2012 - IPC A01G9/20 A01G9/26 

FIELD: agriculture.

SUBSTANCE: light diode radiator comprises a body from a heat conductive material, at least partially ribbed at the rear side. The body has an outlet hole, which is closed with an optically transparent protective glass or a diffuser. Inside the body there are linear boards installed with assembled groups of light diodes with a different spectrum of radiation in the range of spectral efficiency of photosynthesis /400-700 nm/ with optical axes, facing the outlet hole of the body, and connected to a source of supply. At least on two internal side walls of the concave body there is a cascade of longitudinal plates forming terraces from a heat conductive material, which create ribs of an internal radiator of a conductive heat sink. Longitudinal plates are in thermal contact with body walls and face the outlet hole with a flat part. On each plate there are linear boards /lines/ installed in thermal contact, mostly boards with an aluminium base with high-capacity light diodes or light diode modules, or separate light diodes, which are connected in series or in parallel-serial chains to a source of supply.

EFFECT: design will make it possible to improve thermal and spectral characteristics, to increase density of radiation flow with reduced dimensions of a radiator.
