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.
