Abstract
An optical system for a lighting device, comprising a light-guiding optical part configured for spreading light beams generated by light sources situated opposite to a rear side of the optical part. Light beams are coupled into the light-guiding optical part, and after passing through the light-guiding optical part the light beams are emitted through its output surface. Rear side of light-guiding optical part is equipped with macroscopic cavities, each pair of adjacent macroscopic cavities forming between themselves an optical segment, whose two sides, which separate the optical segment from the pair of macroscopic cavities, comprise a reflective surface. The optical segment comprises a rear surface on the rear side, opposite to which a light source is positioned. The reflective surfaces are configured for reflecting a part of the light beams, which were coupled through the rear surface into the optical segment, and then directing them to the output surface.
