Abstract
An optical element, comprising a light guide body. 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 each light-incident unit to be emitted toward the light-emitting part; the shape of a forward projection plane of the light-emitting part is of a strip shape. The optical element can reduce the occupied space and improve the space utilization rate, facilitates reducing positioning mounting errors, has an appearance with a narrow and elongated shape, and can be applied in vehicle lamp modules, vehicle lamps and vehicles.
