Abstract
The invention relates to a microprojection light module (1) for a motor vehicle headlight, comprising at least one light source (2) and at least one projection arrangement (3), which images the light exiting from the at least one light source (2) into a region in front of the motor vehicle in the form of at least one light distribution, wherein the projection arrangement (3) comprises: an entry optics (30), which consists of an array of micro entry optics (31); an exit optics (40), which consists of an array of micro exit optics (41), wherein each micro entry optics (31) is paired with exactly one micro exit optics (41), wherein the micro entry optics (31) are formed in such a way and/or the micro entry optics (31) and the micro exit optics (41) are arranged relative to one another in such a way that the light exiting from a micro entry optics (31) enters precisely only into the paired micro exit optics (41), and wherein the light pre-shaped by the micro entry optics (31) is imaged by the micro exit optics (41) into a region in front of the motor vehicle as at least one light distribution (LV1-LV5; GLV).
