Abstract: An optical system for a motor vehicle headlight, wherein the system includes at least two optical elements, including a light coupling area, a light decoupling area, a lateral surface which delimits the optical element and which has an optically effective aperture edge for forming a bright/dark boundary in a far-field light distribution producible with the optical system. The optical system includes at least two anterior optics, wherein an anterior optic is associated with each optical element, wherein a first anterior optic is configured to direct light beams along a first coupling direction onto the light coupling area of the optical element associated with it.

Abstract: The invention relates to a heat sink (1, 100) for a light source of a motor vehicle light module, wherein: the heat sink (1, 100) comprises a main body (2) and cooling plates (3, 300) which can be arranged on the main body (2); when the cooling plates (3, 300) are connected to the main body (2), the cooling plates (3, 300) are in heat-conducting contact with the main body (2), each cooling plate (3, 300) having a base side (31, 310); the main body (2) has fastening elements (21) on a surface (22), the surface (22) facing the base sides (31, 310) of the cooling plates (3, 300); counter elements (32) mating with the fastening elements (21) are arranged on each base side (31, 310), the fastening elements (21) being designed to engage in the counter elements (32); the fastening elements (21) are arranged in a grid (23); the counter elements (32) are arranged on the respective base sides (31, 310) at regular distances (d1) from one another, and the grid (23) has a grid spacing (d2), the grid spacing (d2) being gre
