摘要： A projection headlight for vehicles, having a first lighting unit containing a light source and a primary optical unit for pre-shaping light exiting the light source, a second lighting unit containing a light source and a primary optical unit for pre-shaping the light exiting the light source, a secondary optical unit for imaging the light exiting the primary optical unit of the first lighting unit in a region in front of the vehicle as a first light distribution and light exiting the primary optical unit of the second lighting unit as a second light distribution, an actuator for actuating the first lighting unit and the second lighting unit in order to generate the light distribution consisting of the first light distribution and the second light distribution, a diaphragm with a diaphragm edge for producing a light-dark boundary in the first light distribution.

摘要： A headlight for a motor vehicle having at least one light source which emits light during operation of the headlight. A primary optical system has at least one light entry surface for the light emitted by the at least one light source and at least one light exit surface. A secondary optical system, which, during operation of the headlight, projects the light emitted from the at least one light exit surface of the primary optical system into the space outside the motor vehicle where it produces a light distribution which has a horizontal cut-off line and light portions located above the cut-off line in order to implement an OS function (overhead sign function). The headlight being designed such that a portion of the light emitted by the primary optical system is reflected back to the primary optical system by the secondary optical system.
