LED LAMP Russian patent published in 2016 - IPC F21K99/00 

FIELD: lighting.

SUBSTANCE: invention relates to lighting engineering. Led lamp contains a led module, mechanically connected with a radiator, inside which there is a voltage converter. Led module consists of two COB (chip-on-board)-elements, each of which contains at least one light-emitting crystal located on the printed circuit board and having electrical connection with it. COB elements adjoin each other and have thermal contact sides, on which there are no led crystals. Primary optics of the led module is made of a translucent material in the form of a biconvex, biconcave, convex-concave, convex-flat or concave-flat three-dimensional volumetric lens having an undercut with guide slots with narrowing sections ensuring tight thermal coupling of two COB-elements installed in the said undercut. Primary optics can be equipped with a disperser in the form of light-scattering particles. Undercut of the primary optics lens can be filled with a transparent elastic polymer, which can also be equipped with a disperser in the form of light-diffusing particles or luminophor.

EFFECT: technical result consists in possibility to form different radiation diagrams, improvement of optical characteristics in wide spectral range, increase in efficiency of heat removal, increase in level of structure protection from influence of adverse environmental factors.
