Optics are provided for use in illumination devices and solar concentrators, the optics having a light guide, a redirecting layer including a plurality of lenses, and a plurality of reflector elements. In illumination devices, light from a light source enters the light guide and is guided therein until it escapes into a reflector element, which reflects at least some of the light received by the reflector element toward a corresponding lens for emission from the illumination device. In solar concentrators, sunlight is received by the lenses, which focus the sunlight onto reflective surfaces of the reflector elements. The reflective surface of each reflector element redirects the light into the light guide, which guides the light toward a solar energy collector, such as a photovoltaic cell. The light from the light guide may be directed onto the solar energy collector by a light conditioning element. |
