The solar reflector (10; 110) comprises a mirror (14; 114) and a supporting structure (16; 116) made of sheet metal supporting the mirror (14;114), wherein the supporting structure (16; 116) comprises a first metal sheet (18; 119) having a plurality of truncated cone-shaped bosses (22; 122a, 122b) obtained by pressing or drawing from a flat metal sheet, and a second metal sheet (20; 120) arranged above the first metal sheet (18; 119) and securely joined to the latter by means of permanent connections (26; 126) so as to give the supporting structure (16; 116) a cellular or honeycomb configuration. The permanent connections (26; 126) are obtained by means of clinching, spot welding, projection welding, laser welding or gluing. The mirror (14; 114) is securely joined to the second metal sheet (20; 120) by means of gluing or mechanical connection. |
