Abstract: A window illumination enhancer having at least one planar reflective surface and two openings is designed to fit in a window well of a building. The surface reflects light from a first of the openings through the window, via the second opening. The first opening is located above the window well. A polymer film surrounds the path of the light between the two openings to reduce soiling of at least the surface. A second planar reflective surface may be included and may be arranged to form a periscopic device, which affords an above-ground view of the exterior. The enhancer may be composed of lightweight materials. It may be freestanding, and may be mounted without fixing to the building wall. Illumination is increased because the view of the dim-lit window well wall is blocked by the more brightly lit surface.
