摘要： A sunlight redirector has a first mirror array formed of a first plurality of substantially parallel, uniformly spaced, longitudinal outward mirror segments; and a second mirror array formed of a second plurality of substantially parallel, uniformly spaced, longitudinal inward mirror segments. Each mirror segment has a normal vector. The outward mirror segments are adjustably positionable, such that their normal vectors remain parallel. The first mirror array is rotatable about a normal vector of the sunlight redirector. The inward mirror segments may remain fixed in position at all times; or they may be moved, twice per day, between first and second fixed positions.
