LIGHTING SYSTEM Russian patent published in 2007 - IPC G02F1/13357 

FIELD: optics.

SUBSTANCE: lighting system comprises, at least, one radiation source, light-conductive layer and an array of light-emitting elements, positioned on the light-conductive layer. Light-emitting elements are made in form of truncated pyramids, lesser bases of which are positioned on the upper surface of the light-conductive layer with creation of optical contact, and side edges of light-conductive elements provide for reflection of light, entering through the base, in a direction which is normal to upper surface of light-conductive layer, while pyramids are made polygonal, greater bases of pyramids are adjacent to each other along perimeter, while the generating line of the side edges is a quadratic curve.

EFFECT: increased efficiency.
