LIGHT REDIRECTION DEVICE Russian patent published in 2017 - IPC F21V5/00 F21V7/00 F21S11/00 G02B6/00 

FIELD: lighting.

SUBSTANCE: device comprises at least one transparent element (10) having a substantially flat upper surface (11) in the xy plane and a substantially planar bottom surface (14), and said upper (11) and lower (14 ) surfaces are angled α relative to each other about the x axis, and light reflector (20) for each transparent element (10) having a flat surface. The said planar surface of said light reflector (20) is substantially parallel to said lower surface (14) of said transparent element (10) and adjacent thereto. Wherein the said reflecting surface is remote at a distance (12) from the said transparent element via a transparent medium having a lower refractive index than transparent element (10) so that light (31) incident on the device is refracted by each interface between materials and reflected by refleting element (20). The method includes the stage of placing said device (1) substantially perpendicular to direct sunlight (31) in the afternoon. One of its side surfaces is adjacent to wall or window (40) of the building.

EFFECT: energy saving.
