Abstract (en)
[origin: EP0933585A1] The headlamp has a light source (10) set in a reflector (20). The light source is cylindrical and is placed horizontally, transverse to the optical axis (y-y) of the reflector. Part of the reflector profile ensures a ray (D1) emitted tangentially from the edge of the source is reflected (D2) parallel to the optical axis, while rays emitted other parts of the source are reflected downward.
