An illumination device () for a motor vehicle headlight, including illumination units arranged next to one another, which respectively have a light source, primary optical device, and a secondary optical device. The primary optical devices are held in a common holding element formed by a transparent body. In the body, an overcoupling protective device in the form of a through hole in the body is provided between two adjacent receiving through holes in which a primary optical device is respectively held. The through hole of the overcoupling protective device is delimited by two side faces, which face the receiving through holes of the primary optical devices. Light deflection means are designed to deflect at least part of the rays of light entering the body such that part of the rays of light does not enter the adjacent illumination unit or strike the secondary optical device of the adjacent illumination unit.

The invention relates to a lighting device () for a motor vehicle headlight for generating a light pattern (LV), particularly an adaptive light pattern, e.g. an adaptive dipped headlight and main beam light pattern, or a part of a light pattern of this kind, wherein the lighting device comprises a number N of preferably identical projection modules (), where N=2, 3, 4 or greater than 4, each of the projection modules () being designed to generate a segment light pattern (LV, LV). The projection modules () are arranged with respect to one another in such a manner than, proceeding from a first projection module (), known as the starting projection module (), which generates what is called the starting segment light pattern (LV), the segment light patterns (LV; LV, LV) of the further projection modules () are displaced laterally in a, particularly in a common, horizontal direction, with the extent of the displacement. VSh, of the nth segment light pattern (LV; LV, LV) of the nth projection module () in said horizontal direction being proportional to (n&#x2212;1)/N times the principal segment width, BR, where n=2, . . . , N, and with at least one of the nth segment light patterns (LV; LV, LV, LV), n=2, . . . , N, being displaced upwards or downwards vertically in respect of the starting segment light pattern (LV).

The invention relates to a motor vehicle headlamp having a shielding screen () for shielding incident solar radiation, wherein the shielding screen is arranged between a lighting unit () having at least one light source (), and a projection optics (). 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 () of the light outlet aperture () of the shielding screen (), deflective structures () 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.
