Abstract
A micro-projection light module (1) for a vehicle headlight, comprising at least one light source (2) and at least one projection arrangement (3) which images the light emitted from the at least one light source (2) into an area 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) having one, two, or more micro entry optics (31) preferably arranged in an array, and an exit optics (40) having one, two, or more micro exit optics (41) preferably arranged in an array, wherein each micro entry optics (31) is paired with precisely one micro exit optics (41), wherein the micro entry optics (31) are designed 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 substantially all the light emitted 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 an area in front of the motor vehicle in the form of at least one light distribution (LV1-LV5; GLV), wherein the at least o…
