Reflector for accommodating an electric lamp |
(57) 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.
