Patent ID: 7607429

Claim:
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.
