1. A headlamp for a motor vehicle, the headlamp comprising:
a plurality of light sources that emit light when in use, wherein the light sources are adjacent to one another in a first direction (X);
a collimator including a plurality of collimating lenses, each of the collimating lenses having an entry surface and an exit surface, wherein the collimating lenses are adjacent to one another in the first direction (X);
a secondary optical element that has having at least one transparent substrate with an entry surface and an exit surface, wherein two sections are adjacent to one another in the first direction (X) on the at least one substrate, wherein an array of cylindrical lenses is positioned in a first section of the two sections, and wherein there is no array of cylindrical lenses in a second section of the two sections;
wherein the light emitted from one of the light sources passes successively through the entry surface and exit surface of one of the collimating lenses and then through one of the sections of the secondary optical element;
wherein an array of refractive structures is positioned in the second section, wherein each refractive structure of the array of refractive structures includes a prism on the entry surface and a prism on the exit surface of the at least one substrate,
wherein, for each refractive structure of the array of refractive structures, light exiting the collimator passes successively through both of the prisms of the refractive structure.
