摘要： The invention relates to a motor vehicle headlamp having a shielding screen (9) for shielding incident solar radiation, wherein the shielding screen is arranged between a lighting unit (2) having at least one light source (3), and a projection optics (8). Said shielding screen has a light outlet aperture for light radiated by the light unit to the front, wherein the light emitted by the lighting unit is projected into the traffic space as a light image by means of the projection optics, and the shielding screen is located outside the focal plane of the projection optics. On the border (13) of the light outlet aperture (10) of the shielding screen (9), deflective structures (14, 15, 16, 17, 18, 19) are formed, a least in some areas, which lead to a deflection of scattered light that is emanating from the lighting unit and is undesirable in the light image.

摘要： A lighting device for a vehicle headlight, the lighting device having a first light module (105), a second light module (106) and a third light module (107), wherein, when the modules are installed in a vehicle, the first light module generates a first overall light distribution (A), the second light module generates a first partial light distribution (F), and the third light module generates a second partial light distribution (Z), these distributions being in a region in front of the vehicle. When the first and second light modules are illuminated at the same time, the first overall light distribution at least partially overlaps the first partial light distribution, forming a second overall light distribution (AF). The second partial light distribution lies underneath the hh line and at least partially overlaps the second overall light distribution (AF). When all three light modules are activated simultaneously, a third overall light distribution (AF′) is formed.
