<p>The invention relates to a collector module (3) having a gutter-like reflector surface (1) which, in cross-section, is composed of circular arcs (100), parabolic arcs (101), elliptical or hyperbolic arcs, the vertices (S) of which each lie on a common base line (11). Said reflector surface is designed, by means of single-axis tracking, to focus the rays of the sun shining in at different angles onto a receiver element (2) arranged coaxially or concentrically with respect to a focal line (f), and said reflector surface has a biaxial curvature and is in each case formed by a family (10) of identical arcs having alternate cut-offs (2p), the focal points (F) of which lie on a common focal line (f), wherein the distance of the base line (11) from the focal line (f) in a collector module (3) changes.</p> |
