Abstract: A radiant energy flux transformation system including a primary linear focus concentrating collector formed by a plurality of cylindrical slat-like reflectors and a secondary elongated collector is described. The reflectors of primary collector generally have concave or planar transversal profiles and are positioned in a stepped arrangement with longitudinal axes being parallel to each other and to the secondary collector. The reflectors are tilted away from the direction to the source of radiant energy at a range of angles being less than 45° to reflect and direct the incident energy flux to a common focal region located below the primary collector where the concentrated flux is intercepted and further transformed by the secondary collector. In addition to efficient concentrating radiant energy such as sunlight, the system can provide uniformity or a desired energy distribution in the concentrated flux.

Abstract: A radiant energy collecting and converting device having at least one array of slat-like concave reflective elements and an elongated receiver. The device efficiently concentrates and converts radiant energy, such as sunlight, to other useful types of energy, such as electricity and heat. The mirrored surfaces of reflective elements having appropriate individual profiles represented by curved and/or straight lines are positioned so that the energy portions reflected from individual surfaces are directed, focused, and superimposed on one another to cooperatively form a common focal region on the receiver. The mirrored surfaces are inclined towards one another at their rear ends facing the receiver and can be arranged to provide lens-like operation of the array. The receiver can be arranged in line photovoltaic cells or a tubular solar heat absorber.

Abstract: A non-imaging energy flux transformation system including a concentrator incorporating a set of nested, ring-like, concave reflective elements, and a receiver. The system efficiently concentrates radiant energy, such as sunlight, by means of focusing the energy striking the entrance aperture of concentrator to the receiver located on the side of concentrator's exit aperture. The mirrored surfaces of reflective elements having appropriate individual non-imaging profiles represented by curved and/or straight lines are positioned so that the energy portions reflected from individual surfaces are directed, focused, and superimposed on one another to cooperatively form a common focal region on the receiver. The receiver can be an energy absorbing device, a secondary energy concentrating transformer, or a flux homogenizer.
