LED-BASED LIGHT SOURCE FOR LIGHT FIXTURES OF SANITARY GRADE Russian patent published in 2014 - IPC F21S4/00 F21V5/04 H01L33/00 

Abstract RU 2518181 C2

FIELD: electricity.

SUBSTANCE: invention relates to lighting engineering. The light source consists of a printed circuit board dissipating heat, a LED array pack, a beam splitter and reflector. The LED array pack is fixed to the printed circuit board and covered by the beam splitter which, in its turn, is pressed to the reflector and positioned with it. The central light beams from the LED array pack are collimated by the beam splitter for the purpose of projection outside. Side light beams are refracted in the direction by the beam splitter, intercepted by the reflector and redirected to the target area of lighting together with the central beams.

EFFECT: low power consumption and simplification of manufacture.
