  • Descrição: In combination with a building, a system for supplying daylight to an interior portion of the building including rooms located at a significant distance from exterior windows of the building is described comprising: a first component having a generally planar configuration and disposed at an angle between an upper story portion and a wall portion of the building on a side thereof which receives sunlight; a parabolic reflector operatively mounted behind the first component relative to the origin of the sunlight for receiving and reflecting sunlight having a low trajectory which passes through the first component; flat light reflecting means disposed in operative association with the parabolic reflector and the first component to reflect light from the parabolic reflector, and sunlight having a high trajectory which passes through the first component, into an interior portion of the building; and further reflective surfaces for dispersing and diffusing light reflected by the flat reflecting means into interior portions of the building, including at least one room, remote from exterior windows. The first component is a unitary structure comprising: frame means; a pair of spaced rollers rotatable about generally parallel axes of rotation and mounted to the frame means; a sheet of material coupled at each end thereof to one of the rollers, respectively, and extending therebetween and having at least two distinct portions. Each of the distinct portions has substantially the same width and height as the chamber and has different light transmission properties for affecting at least one of the amount and the wavelength of light which passes therethrough after first passing through the transparent panel means; and means for effecting rotation of the rollers to control which of the distinct portions of the sheet is disposed in operative association with the transparent panel means at any one time.
