Abstract
A headlamp includes adjacent light sources. A collimator contains adjacent collimating lenses, each with an entry and an exit surface. A secondary optical element has at least one transparent substrate with an entry and an exit surface. Two sections are adjacent to one another on the substrate. An array of cylindrical lenses is placed in a first section, and there is no array of cylindrical lenses in a second section. The light emitted from one light source to pass successively through the entry and exit surfaces of one of the collimating lenses and then through one of the sections of the secondary optical element. An array of refractive structures is placed in the second section, each of which contains a prism on the entry and exit surfaces. The refractive structures cause the light exiting the collimator to pass successively through both prisms of one of the refractive structures.
