ABSTRACT:
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.
