Abstract (en)

[origin: EP0709619A1] A headlight including a light source (3) and a reflector (5), and wherein the reflector (5) collects the source-emitted light over 360 DEG about the source (3) to emit a beam concentrated entirely below the cutoff line (2). The reflector (5) presents a complex reflecting surface including four sectors (10,11,12,13), a first pair (10,11) of which is located on one side of the optical axis (4), and a second pair (12,13) of which is located on the opposite side. The surfaces of the sectors in each pair are connected continuously to each other at respective half planes (A,B) extending through the optical axis (4) and arranged according to the cutoff line (2), form a respective branch of an ellipse (20,21) at each half plane (A,B), and are defined over at least 75% of their angular extension by the envelope of arcs (33,34,35,36) having centers (C1,C2,C3,C4) offset on either side of the optical axis (4). The source (3) is defined by a filament centered on the optical axis (4) but off-centered axially in relation to a first focal point (F) common to the ellipse branches (20,21). <IMAGE> <IMAGE>
