Abstract (en)
[origin: WO2020127083A1] The invention relates to a lighting device (1) for a motor vehicle headlight for generating a light pattern (LV), particularly an adaptive light pattern, for example 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 (10, 20), where N = 2, 3, 4 or greater than 4, each of the projection modules (10, 20) being designed to generate a segment light pattern (LV10, LV20). The projection modules (10, 20) are arranged with respect to one another in such a manner that, proceeding from a first projection module (10), known as the starting projection module (10), which generates what is called the starting segment light pattern (LV10), the segment light patterns (LV20; LV20, LV30) of the further projection modules (20) are displaced laterally in a, particularly in a common, horizontal direction, with the extent of the displacement, VSh, of the n-th segment light pattern (LV20; LV20, LV30) of the n-th projection module (20) in said horizontal direction being proportional to (n – 1)/N times the principal segment width, BR, where n = 2, …, N, and with at least one of the n-th segment light patterns (LV20; LV10, LV20, LV30), n = 2,..., N, being displaced upwards or downwards vertically in respect of the starting segment light pattern (LV10).
