SUNLIGHT CONDENSING STRUCTURE OF NATURAL LIGHTING APPARATUS USING PRISMS, CAPABLE OF REDUCING ENERGY CONSUMPTION IN A BUILDING

摘要

PURPOSE: A sunlight condensing structure of a natural lighting apparatus using prism is provided to efficiently condense sunlight by using prism or fresnel panels installed on the front, sides, and top of a condensing duct.;CONSTITUTION: A front prism panel(10) is inclined toward about a horizontal plane at an angle(Θ1) of between 61 and 90 degrees. A top prism panel(20) is connected to the top of the front prism panel, and inclined toward about a horizontal plane at an angle(Θ2) of between 0 and 29 degrees. Front ends and top ends of a pair of side prism panels are connected to the side ends of the front prism panel and the top prism panel. Both side ends and an upper end of a rear panel are connected to the rear ends of the side prism panel and the rear end of the top prism panel. The rear panel is configured to stand upright about a horizontal plane at an angle(Θ3) of 90 degrees.;COPYRIGHT KIPO 2013
