Title:
マスクおよび多焦点レフレクタ付き放電ランプを有する自動車用ヘッドランプ
Document Type and Number:
Japanese Patent JP4011697
Kind Code:
B2
Abstract:
A motor vehicle headlamp has a discharge lamp, a reflector and a smooth or nearly smooth cover lens, the reflector being adapted to generate a beam below a cut-off line. At least two masks are associated with the discharge lamp, and define two shadow zones on the reflector; the reflector includes at least two reflective zones for forming portions of the beam below the cut-off line, with different amounts of sideways spreading of the light; and these zones of the reflector are separated by generally radial transition planes, at least some of which extend into the shadow zones. A particular application is to enable wide cruising beams to be produced to European standards without any optical anomalies.
