1. A vehicle light optical element assembly, comprising a low-beam primary optical element, a high-beam primary optical element provided below the low-beam primary optical element, and a lens provided on the front end of the low-beam primary optical element and/or the high-beam primary optical element, wherein
the low-beam primary optical element is integrated with the lens; the low-beam primary optical element sequentially, from back to front, comprises at least one low-beam condensation part and a low-beam light passing part; the low-beam light passing part and a lens light-incidence part are integrated; a front edge of a lower surface of the low-beam light passing part is formed into a low-beam cut-off line structure; the high-beam primary optical element comprises at least one high-beam condensation part; a high-beam light-exiting surface is formed at a front end of the high-beam condensation part; and a high-beam light-exiting surface is formed at a front end of the high-beam condensation part, and there is a gap between the high-beam light-exiting surface and the lens light-incidence part, and there is no high-beam light passing part set on the high-beam primary optical element; or
the high-beam primary optical element is integrated with the lens; the high-beam primary optical element sequentially, from back to front, comprises at least one high-beam condensation part and a high-beam light passing part; the high-beam light passing part and the lens light-incidence part are integrated; and a front edge of an upper surface of the high-beam light passing part is formed into a high-beam cut-off line structure; the low-beam primary optical element comprises at least one low-beam condensation part; a low-beam light-exiting surface is formed at a front end of the low-beam condensation part; and a low-beam light-exiting surface is formed at a front end of the low-beam condensation part, and there is a gap between the low-beam light-exiting surface and the lens light-incidence part, and there is no low-beam light passing part set on the low-beam primary optical element; and
the lens comprises a lens light-incidence part and a lens light-exiting part; the lens light-incidence part is a plane, a backwards protruding curved surface or a forwards protruding curved surface; and the lens light-exiting part is a forwards protruding curved surface; and the low-beam primary optical element and the high-beam primary optical element are suitable for focusing and collimating light and then forming a low-beam lighting light shape and a high-beam lighting light shape via the lens.
