Motor vehicle headlight, suitable for emitting a beam limited by a cut-off, and including a modified rear portion |
摘要 |
A motor vehicle headlight of the type suitable for emitting at least one beam that is delimited by a top cut-off and that includes an approximately central concentration spot, the headlight comprising: a filament lamp (100); a reflector (200); and a closure glass (300); the headlight including the improvements whereby said reflector comprises: at least two lateral zones (202, 202') that form small images of the filament defining said concentration spot and forming said cut-off; and a central zone (201, 201, 203, 203') which reflects the light rays emitted by the filament to cause them to converge in a region at a substantial distance from the closure glass while simultaneously forming large filament images which are spread out below said cut-off; with said lateral zones and said central zone joining one another with second order continuity in two essentially vertical planes that are parallel to a central optical axis of the headlight and are disposed on either side thereof.
