Abstract

A concentrator (10) of sun rays comprising: a reflective body (15) adapted to reflect incident sun rays towards a focal segment (SF) at which the reflected sun rays intersect, wherein the reflective body (15) comprises a plurality of reflective first sheets (40) alongside each other along a flanking direction parallel to the focal segment (SF) and each of which is inclined with respect to a plane perpendicular to a plane passing through the middle point (PM) of the focal segment (SF) and orthogonal to the focal segment itself, wherein each first sheet (40) comprises a reflective surface defined by a plurality of parabolas (401), which are alongside each other with respect to the flanking direction of the first sheets (40) and each have a vertex (Vn1) placed on a vertex segment (SV1), which joins all the vertices (Vn1) of the parabolas (401) of each first sheet (40) have a focal distance varying along the flanking direction and are configured such that each parabola has a focal point (F1, Fn1, F2) placed on the focal segment (SF).

Abstract

An assembly (1) for conveying solar rays, particularly for systems for converting solar energy into electric power and/or thermal energy, which comprises a structure (5) for supporting at least one conveyance device, comprising a plurality of conveyance devices, each of which comprises at least one sheet (2) made of a material that is optically reflective and has at least one profile that is substantially curved along a single axis of curvature (C1), the profile having a substantially parabolic shape for obtaining the focused reflection of a concentrated luminous image (3) having a substantially rectangular shape, the conveyance devices being associated jointly with the supporting structure (5) and being arranged substantially laterally adjacent to one another without discontinuities, so as to obtain the focal reflection of a substantially rectangular concentrated luminous image (3).
