LUMINAIRE Russian patent published in 2014 - IPC A01G9/20 F21V7/00 

FIELD: electricity.

SUBSTANCE: invention refers to agriculture, particularly to luminaries for seedling, vegetable or flower growing at home or on industrial scale, and can be used in other economy sectors requiring individual lighting, e.g. in breeding of various animals. Luminaire includes emitter and reflector. Luminaire features polariser at optic output or on the way of light stream from emitter. Polariser can be made in the form of dielectric grid or as a film applied on reflective surface of reflector etc. Polarising dielectric in the polariser has medium interfaces, e.g. air-glass. Polarisation surfaces at dielectric medium interfaces are positioned at an angle to falling rays of emitter and are determined by polarisation angle zone.

EFFECT: simplified device design, enhanced efficiency of active photosynthetic irradiation leading to increased vegetation and reduced period of plant growth, spared power, reduced cost of device.
