1. An optical element, comprising a light guide body, wherein the light guide body comprises a plurality of light-incident parts arranged along a length extension direction of the light guide body, a light guide part and a light-emitting part; each light-incident part is provided with at least one light-incident unit; the light guide part is configured to guide light received by the light-incident units to be emitted towards the light-emitting part; the shape of a forward projection surface of the light-emitting part is of a strip shape; at least one groove structure is formed on the light guide part; and a cut-off part used for forming a light shape cut-off line is formed on one of the groove structures; the light received by several light-incident parts corresponding to the cut-off part is cut off by the cut-off part, and is then emitted from the light-emitting part of the light guide body to form a low beam light shape with a low beam cut-off line, and the rest of the light-incident parts are used to form a high beam light shape;
a plurality of light-incident units are connected in sequence and disposed on the corresponding light-incident part, and the light-incident unit is a protrusion protruding towards a light-incident side.
