  • Publication number: 20220120401
    Abstract: 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.

  • Publication number: 20220074564
    Abstract: A vehicle lighting module comprises a primary optical element and a secondary optical element. The primary optical element comprises at least one light entrance part, a light transmission part, and a light exit part sequentially provided along a light exit direction. Either the optical axes of the light entrance parts on either side of the primary optical element incline towards an optical axis of the secondary optical element and the light exit part is a concave arc surface, or the direction of the optical axis of the light entrance part is the same as that of the optical axis of the secondary optical element and the horizontal cross-sectional line and/or vertical cross-sectional line of the light exit part is configured as a curved line protruding forward. The vehicle lighting module has a small volume while ensuring light effects, and can be adapted to narrow and compact vehicle lamp modeling.

  • Publication number: 20220065416
    Abstract: A vehicle lamp, a vehicle, and a vehicle lamp illumination module. The vehicle lamp illumination module comprises light sources, a low-beam primary optical element, a high-beam primary optical element, and a secondary optical element. The low-beam primary optical element can guide light to be sequentially emitted via the low-beam primary optical element and the secondary optical element to form a low-beam shape. The high-beam primary optical element comprises multiple collimation units, wherein the surfaces of light emitting ends of the collimation units are connected together or integrally formed to form a high-beam light emitting surface. Light incident ends of the collimation units have one-to-one correspondence to the light sources, so that the light can be sequentially emitted via the high-beam primary optical element and the secondary optical element to form a lightless shape. The module has accurate light shape control, is precise in assembly, and high in light energy utilization.

  • Publication number: 20210310628
    Abstract: Disclosed are a lighting module, a vehicle lamp and a vehicle. The lighting module includes a plurality of high-beam light sources, a plurality of low-beam light sources, a high-beam optical element and a low-beam optical element. The high-beam optical element includes a plurality of high-beam light guide bodies, which are in one-to-one correspondence with the plurality of high-beam light sources. The low-beam optical element includes at least one low-beam light guide body, the plurality of low-beam light sources are disposed at a rear end of the at least one low-beam light guide body, and a front end of the at least one low-beam light guide body forms a continuous low-beam light emitting surface. The low-beam optical element and the high-beam optical element are disposed one above the other, an upper boundary of the high-beam light emitting surface.
