Abstract
A light shelf for daylighting an interior space with reflected sunlight has a reflective upper surface having a cyma-reversa profile along a vertical cross-section perpendicular to the window, with a convex region adjacent to the window and a concave region distal from the window.
Claims17
A light shelf mounted horizontally in an interior room adjacent to a window to reflect sunlight passing through the window upward onto the ceiling of the room, said light shelf comprising:
- a reflective upper surface having a cyma-reversa profile along a vertical cross-section perpendicular to the window, with a convex region adjacent to the window and a concave region distal from the window.
A light shelf mounted horizontally in an interior room adjacent to a window to reflect sunlight passing through the window upward onto the ceiling of the room, said light shelf comprising:
- a thin upper panel with a reflective surface having a cyma-reversa profile along a vertical cross-section perpendicular to the window, with a convex region adjacent to the window and a concave region distal from the window, said upper panel also having a window edge adjacent to the window and a distal edge opposing the window edge;
- a thin lower panel spaced apart from the upper panel having a window edge adjacent to the window and a distal edge opposing the window edge;
- and
- a nose cap engaging the distal edges of the upper and lower panels;
- and
- a base plate engaging the windows edges of the upper and lower panels, said base plate.
A light shelf mounted horizontally in an interior room adjacent to a window to reflect sunlight passing through the window upward onto the ceiling of the room, said light shelf comprising:
- a reflective upper surface having a cyma-reversa profile along a vertical cross-section perpendicular to the window with a convex region adjacent to the window curving downward to disperse reflected sunlight over a large area of the ceiling, and a concave region continuing from the convex region distal from the window to reflect sunlight in an area of the ceiling that at least partially overlaps the area of sunlight reflected by the convex region.
