1. A headlight for a motor vehicle, the headlight comprising:
a first luminous surface, wherein the headlight is configured so that light emanates from the first luminous surface and is used to generate a high-beam light distribution;
a second luminous surface, wherein the headlight is configured so that light emanates from the second luminous surface and is used to generate a forefield portion of a low-beam light distribution;
projection optics configured so as to project light emanating from the first and second luminous surfaces into an area around the motor vehicle; and
a heat sink,
wherein the first luminous surface corresponds to an active area of a solid-state LED array,
wherein the second luminous surface is formed by a converter or a scatterer that is illuminated by at least one light-emitting diode during operation of the headlight,
wherein the heat sink has a step to form a first mounting surface and a second mounting surface, the second mounting surface being offset from the first mounting surface by the step, and the first mounting surface and the second mounting surface being parallel to one another,
wherein the first luminous surface is mounted on the first mounting surface of the heat sink and the at least one light-emitting diode is mounted on the second mounting surface of the heat sink,
wherein the converter or the scatterer, that forms the second luminous surface, is arranged in a same plane as the first luminous surface.
