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.

Dependent claims

A multistage system for radiant energy flux transformation comprising:

a primary energy collector comprising a plurality of spaced apart non-transparent elongated reflective elements oriented generally parallel to a reference line, said reflective elements having mirrored surfaces being inclined at predetermined angles to direct parallel incident rays toward a plurality of converging directions through spaces between adjacent pairs of said reflective elements and by means of single stage specular reflection, said angles being such as to result in the reflection of said parallel rays at a range of angles of incidence having particular values more than 45° and less than 90°, at least one mirrored surface having a concave transversal profile;
and
an elongated secondary energy collector extending parallel to said reference line and disposed in energy receiving relation to at least one of said mirrored surfaces;
wherein at least a portion of radiant energy flux impinging on and reflected from said surfaces of said primary energy collector is intercepted and redirected by said secondary energy collector toward a predetermined direction so as to result in an improved transformation of said radiant energy flux.
