Abstract (en)
[origin: EP0503708A2] The reflector (1) of metal sheet has a concave, reflecting surface (2) having an optical axis (3), and a light emission window (4) transverse to the axis (3). The reflecting surface (2) shows a plurality of flat lanes (5) which approach the axis (3) from the window (4) curves and gives the reflector (1) polygonal sections transverse to the axis. In an area adjacent the window (4) the lanes (5) are divided into flat sublanes (51-55), which sublanes have in sections transverse to the axis (3) mutually similar directions, and are located adjacent a circumscribed curve (6). The reflector is easy to manufacture.
