LIGHT-EMITTING DIODE LIGHTING FIXTURE Russian patent published in 2015 - IPC F21V7/00 F21Y101/02 

FIELD: electricity.

SUBSTANCE: invention is related to light engineering, in particular, to energy-saving lighting fixtures without dazzling effect, which are designed on the basis of powerful light-emitting diodes (LEDs) with large service life. The lighting fixture comprises a power supply unit, a body, a dissipating cover, a board with mounted LEDs and several refracting plates made as partially refracting plates. The partially refracting plates are mounted normally towards the sectional plane passing perpendicular to the board and the body plane and at the same time slantwise towards the body at different angles in space between the body and dissipating cover. The LED lighting fixture may be equipped with butt-end refracting plate installed slantwise towards the body between the body and dissipating cover behind the refracting plate last in succession as well as the face refracting plate mounted between the partially refracting plates and the body. The butt-end and front refracting plates have high light reflectance. The partially refracting plates may be made as optically transparent plates.

EFFECT: removal of dazzling effect and simplification of the lighting fixture design.
