LED LAMP (EMBODIMENTS) FOR LIGHTING OF AGRICULTURAL CROPS Russian patent published in 2019 - IPC F21S4/00 

FIELD: lighting.

SUBSTANCE: group of inventions relates to LED lighting fixtures (embodiments) for illuminating agricultural crops. LED lamp comprises radiator housing in the form of longitudinal V-shaped profile of constant cross section along length, with angle α tilting to the horizontal of two faces of the profile, on each of which at least one LED module is placed. In the lighting fixture according to the first embodiment, the LED module is made in the form of a LED matrix, and the matrices are arranged on the profile edges uniformly along its length in a staggered order, differs by the fact that the thickness of the profile walls on each of its cross-section sections obeys the relationship a < b < c where a is thickness of wall of outer section of profile, b is the thickness of the wall of the middle section of the profile in the attachment point of the LED matrix, c is the wall thickness of the central section of the profile. In the lighting fixture according to the second embodiment, the LED module is made in the form of a linear board with a plurality of distributed point light-emitting diode light sources, characterized in that the thickness of the profile walls on each of its cross-section sections obeys the relationship a < b > c, for a < c, where a is the thickness of the wall of the outer section of the profile, b is the thickness of the wall of the middle section of the profile in the attachment point of the LED linear board, and c is the thickness of the wall of the central section of the profile.

EFFECT: technical result is achieving maximum efficiency of heat sink of radiator housing.
