A stack of light-deflecting elements are installed in a window. Each deflecting element has a solar ray inlet, a curved middle section and an end comprising a ray outlet into the room. Each element is rectilinear at the outlet end so that rays are dispersed and emerge from the light-deflecting elements in prisms of rays, the bottom edge of which is horizontal. The solar rays entering the light-deflecting elements are subjected to multiple total internal reflections at a different angle. The angle of the normal line of the deflector elements to the horizontal is selected so that the largest possible amount of sunlight can be captured and conveyed into the room to illuminate the room with a uniform, diffuse distribution.

[ What is claimed is:] [1.] A window apparatus for providing glare-free diffused sunlight to a room, said apparatus comprising at least one light-deflecting element having an inlet face adapted to be exposable to the sun's rays, an outlet face adapted to be exposable to the room to be lit and an intermediate section for guiding and dispersing the sun's rays to and through said outlet face toward a selected location in the room, the said inlet face and said outlet face being disposed at an angle to each other and the intermediate section being curved and being formed rectilinearly at least at its end adjoining the outlet face to have mutually opposing peripheral faces forming a guide path for said rays.
