    摘要： A primary optics (100) for a motorcycle headlamp, the primary optics (100) is a non-imaging primary optics configured to irradiate a segmented light distribution (LD1) in front of the primary optics (100), wherein the primary optics (100) comprises:
    - a plurality of light guiding elements (200) for forming a predetermined segmented light distribution (LD1) from light of light sources (50) in a main direction (X), wherein each light guiding element (200) has a light input surface (210) and a common light output surface (220), wherein the light guiding elements (200) are arranged in groups (GP1, GP2, GP3), wherein each group (GP1, GP2, GP3) comprises at least two light guiding elements (200) arranged in juxtaposition along a straight arrangement line (AL1, AL2, AL3) orthogonal to the main direction (X), wherein the light segments (LS1, LS2, LS3) generated by the light guiding elements (200) of a group (GP1) are irradiated in juxtaposition along a straight irradiation line (IL) corresponding to and parallel to respective straight arrangement line (AL1) of the respective group (GP1), wherein the common light output surface (220) comprises a homogenization structure (300), wherein the homogenization structure (300) is formed of a plurality of grooves (310), each of which extends along an extension line (EL) transverse to the straight arrangement line (AL1, AL2, AL3) of each group (GP1, GP2, GP3) of light guiding elements (200), wherein the groove (310) having a constant radius (R) in a cross-section orthogonal to the extension line (EL) along the extension line (EL), and wherein the grooves (310) being arranged with respect to each other in such a way that the extension lines (EL) of the grooves (310) are parallel to each other.
