<p>A device redirects and concentrates direct sunlight into buildings. The device includes: at least one transparent element having a substantially planar top surface in an x-y-plane and a substantially planar bottom surface, wherein the top and bottom surfaces are arranged at an angle with respect to each other around the x-axis; and a light reflector for each transparent element. The light reflector has a reflective surface arranged substantially parallel and adjacent the bottom surface of the transparent element. The reflective surface is spaced apart from the transparent element by a transparent medium having a lower refractive index than the transparent element. Light incident to the device is refracted by each material transition interface and reflected by the reflecting element. By arranging the device substantially perpendicular to direct sunlight at noon, with one of its edges adjacent a building wall or window, the device can redirect and concentrate sunlight into buildings.</p> |
