摘要： An optical system for a motor vehicle headlight, wherein the system includes at least two optical elements, including a light coupling area, a light decoupling area, a lateral surface which delimits the optical element and has an optically effective aperture edge for forming a bright/dark boundary in a far-field light distribution producible with the optical system. The system includes at least two anterior optics, wherein an anterior optic is associated with each optical element. The first anterior optic and first optical element are configured to produce a first far-field light distribution, wherein the second anterior optic and second optical element are configured to produce a second far-field light distribution, which lies below the bright/dark boundary of the first far-field light distribution.

摘要： Illumination device for a motor vehicle headlight for producing a dipped beam distribution, which has a homogeneous light distribution in the region below the intersection HV up to at least −3° along the vertical line V-V. The illumination device includes: (i) an illuminant for emitting light, (ii) a screen with a screen edge, wherein the screen includes a first and a second screen section, which are connected by a connecting section, and (iii) a projection optics system, which is designed to project the dipped beam distribution towards a main emission direction. The connecting section has a deflection surface, which extends along a plane with a spatial vector, which forms a first angle of 1° to 3°, preferably of 2°, to the first axis, and forms a second angle of 1° to 3°, preferably of 2°, to the main emission direction.
