<p>A concentrator of solar radiation comprises a carrying structure (1) on which are mounted, in annular rows, facets (2) the reflecting surfaces of which are split into annular zones (3). At least one of the peripheral annular zones (3) has a toroidal surface the generatrix (4) of which has the form of a bow. The centre (5) of curvature of the generatrix (4) is located, in relation to the latter on the other side of the optical axis (6) of the concentrator. The geometrical parameters of the annular zone (3) with the toroidal surface are chosen so as to ensure that from among all the rays falling on it parallel to the optical axis (6) of the concentrator two rays (7, 8) are focused on the theoretical focus (F).</p> |
