Lens unit, optical lens, illumination module, vehicle light, and vehicle

An illumination module, comprising an optical lens, wherein the optical lens comprising a plurality of lens units, wherein the lens units are arranged along a left-right direction and each comprise a light incident portion and light emergent portion, and individual light emergent portions are connected to form a light emergent surface, and a plurality of light sources, wherein the light sources are arranged corresponding to light incident portions, so that light emitted from the light sources can enter the optical lens through corresponding light incident portions;

• the illumination module further comprising a plurality of primary optical elements in one-to-one correspondence with the light sources, and the primary optical elements are arranged in a manner of being capable of converging and projecting light emitted by the light sources to the corresponding light incident portions, and directing the light into the optical lens;
• wherein each of the primary optical elements is a reflecting mirror;
• wherein each of the primary optical elements is provided with a main low-beam cut-off line structure or an auxiliary low-beam cut-off line structure;
• and the boundary of the plurality of reflecting mirrors on the side closest to the corresponding light sources is provided with the main low-beam cut-off line structure and the auxiliary low-beam cut-off line structure;
• wherein a curvature of a light incident portion corresponding to the auxiliary low-beam cut-off line structure is larger than a curvature of a light incident portion corresponding to the main low-beam cut-off line structure;
• and
• wherein a lens unit of the plurality of lens unit comprises a light incident portion collimating light in a first single direction and a light emergent portion collimating light in a second single direction, so as to be capable of forming an asymmetric light pattern.
