Abstract

See full text

A passive collimating skylight system includes an energy-receiving aperture defining a first plane and an energy-delivering aperture defining a second plane that is spaced apart from and non-parallel to the first plane. An energy-directing passageway extends between the energy-receiving aperture and the energy-delivering aperture to redirect radiant energy incident on the energy-collecting aperture over a range of incidence angles to the energy-delivering aperture so that the redirected radiant energy emerges from the energy-delivering aperture over a range of emergence angles that is smaller than the range of incidence angles. The passageway is defined by a wall having a first end that defines the energy-delivering aperture and a second end that defines the energy-collecting aperture, the wall tapering inwardly and having a reflective inner surface along substantially the entire length from the first end to the second end. At least a portion of the wall of the passageway can be made of a flexible reflective film.
