LIGHTING FIXTURE Russian patent published in 2015 - IPC F21V9/14 G02B5/30 A01G9/20 

FIELD: electricity.

SUBSTANCE: lighting fixture comprises light emitter (1) with reflector (3) and two-section polarizer. The two-section polarizer is formed with polarizing dielectrics, at that the first dielectric is placed at inner side of the reflector while the second one is placed at surface of dielectric core (6) mounted at symmetrical optical axis of the reflector. The polarizing dielectrics are of film type, single-layer or multilayer. The two-section polarizer may be equipped with electrostatic or magnetostatic tuning mechanism of the dielectric core. Magnetostatic unit may be based on permanent magnets or electromagnets.

EFFECT: improved efficiency factor of photosynthetically active emitted radiation, reduced power consumption, improved growth of plants.
