Transparent light deflecting panel for daylighting rooms

Claim 1

A plane panel adapted to be mounted in vertical orientation in an opening in the facade of a building so as to redirect incident daylight towards the ceiling of said building, said panel comprising: a transparent plastic plate having a plurality of parallel equally spaced apart laser cuts made perpendicularly through said plate such that said plate is divided into a series of parallel, equally spaced apart horizontally aligned parallelpipeds of rectangular cross section, said parallelpipeds being suppored by a narrow continuum of said transparent plate extending around the periphery of said transparent plate and extending at intervals across said transparent plate in a direction perpendicular to the horizontal axis of said parallelpipeds.

Claim 7

A method of controlling the direction and amount of daylight entering a building comprising the steps of: incorporating a plurality of transparent light deflecting plates into louvered panels in an external opening in said building, wherein each of said plates has a plurality of parallel equally spaced apart laser cuts made perpendicularly through said plate such that said plate is divided into a series of parallel, equally spaced apart horizontally aligned parallelpipeds of rectangular cross section, said parallelpipeds being supported by a narrow continuum of said transparent plate extending around the periphery of said transparent plate and extending at intervals across said transparent plate in a direction perpendicular to the horizontal axis of said parallelpipeds; adjusting said louvered panels to the substantially closed position such that sunlight incident on said louvered panels is substantially transmitted into said building and deflected towards the ceiling, or adjusting said louvered panels to the substantially open position such that sunlight incident on said louvered panels is substantially deflected to the exterior of said building.

Claim 8

A method of controlling the direction and amount of daylight entering a building comprising the steps of: incorporating a plurality of transparent light deflecting plates into louvered panels in an external opening in said building, wherein each of said plates has a plurality of parallel equally spaced apart laser cuts made perpendicularly through said plate such that said plate is divided into a series of parallel, equally spaced apart horizontally aligned parallelpipeds of rectangular cross section, said parallelpipeds being supported by a narrow continuum of said transparent plate extending around the periphery of said transparent plate and extending at intervals across said transparent plate in a direction perpendicular to the horizontal axis of said parallelpipeds; adjusting said louvered panels to the substantially closed position such that sunlight incident on said louvered panels is substantially transmitted into said building and deflected towards the ceiling, or adjusting said louvered panels to the substantially open position such that sunlight incident on said louvered panels is substantially deflected to the exterior of said building.

Claim 9

A method of controlling the direction and amount of daylight entering a building comprising the steps of: incorporating a plurality of transparent light deflecting plates into louvered panels in an external opening in said building, wherein each of said plates comprises a planar transparent plastic plate having parallel equally spaced apart laser cuts perpendicular to the surface of said plate, the depth of said laser cuts being such that the ratio of the spacing to the depth is less than unity; adjusting said louvered panels to the substantially closed position such that sunlight incident on said louvered panels is substantially transmitted into said building and deflected towards the ceiling, or adjusting said louvered panels to the substantially open position such that sunlight incident on said louvered panels is substantially deflected to the exterior of said building.

Claim 10

A method of controlling the direction and amount of daylight entering a building comprising the steps of: incorporating a plurality of transparent light deflecting plates into louvered panels in an external opening in said building, wherein each of said plates comprises a planar transparent plastic plate having parallel equally spaced apart laser cuts perpendicular to the surface of said plate, the depth of said laser cuts being such that the ratio of the spacing to the depth is less than unity; adjusting said louvered panels to the substantially closed position such that sunlight incident on said louvered panels is substantially transmitted into said building and deflected towards the ceiling, or adjusting said louvered panels to the substantially open position such that sunlight incident on said louvered panels is substantially deflected to the exterior of said building.
