Abstract (en)
[origin: WO2006027230A1] The invention relates to an optical system for a motor vehicle headlight, an illumination device for a motor vehicle headlight and a motor vehicle headlight comprising illumination devices of this type. The inventive optical system comprises an optical primary element (2) and an optical secondary element (3). The optical primary element is provided with an irregularity (10), which generates two light-beam sub-bundles, at least one of said bundles being sharply delimited. Said sharp delimitation can be used to generate a light-dark boundary.
