Vehicle light optical element, vehicle light module, vehicle headlight, and vehicle

A vehicle light optical element (VLOE) comprises a light incident portion, a transmission portion, and a light emitting portion sequentially arranged from back to front. The light incident portion comprises an illuminating light incident structure (ILIS) and at least one high-beam light incident structure (HBLIS), in which an illuminating light incident surface of the ILIS is adapted to receive auxiliary light during low-beam lighting. Alternatively, the light incident portion comprises an ILIS and at least one HBLIS, in which the ILIS is either a flat surface, a curved cylindrical body protruding backwards, a hemispherical body protruding backwards, or a light condensing structure. The ILIS is adapted to receive auxiliary lighting light during low-beam lighting. The ILIS is provided on the VLOE, such that when a vehicle light is in a low-beam lighting mode, the VLOE is also luminous, thereby improving the aesthetic appearance of the vehicle light.

Low-beam headlight element for a vehicle

A low-beam headlight element includes a lens (301) for modifying the distribution pattern of light penetrating the lens, and a reflector element (302) including a first end having a place for a light source (303) and a second end having an opening constituting a passage for the light penetrating the lens. The thickness of the lens is shaped to decrease more strongly towards a first edge (303) of the lens than towards an opposite second edge of lens so as to provide more refractivity on a first area of the lens abutting on the first edge than on a second area of the lens abutting on the second edge. The refractivity on the first area produces a cutoff line in a resulting light distribution pattern. Hence, for achieving a cutoff line meandering in a desired way, there is no need for a screen element which converts light into heat.
