  • Patent number: 10119667
    Abstract: Light-redirecting optical system for building fenestrations, such as glass doors and windows, storefront glazing systems, and curtain walls, that can collect and redirect daylight into the interior of a building. The light-redirecting optical system includes an outward-facing light-redirecting optical surface and an inward-facing light-redirecting surface. The outward-facing light-redirecting optical surface collects and redirects daylight mostly upward toward the inward-facing light-redirecting surface. The inward-facing light-redirecting surface receives the redirected daylight and further redirects it into the interior environment at pre-determined angles; so that all specular rays of light are at or above the horizon for a wide range of incident angles of daylight striking the outward-facing light-redirecting optical surface. The light-redirecting optical surfaces can be fabricated on a film or flexible substrate that may be directly applied to glass, acrylic, or other glazing surfaces.
