VEHICLE LIGHT OPTICAL ELEMENT ASSEMBLY, VEHICLE LIGHTING DEVICE, VEHICLE LIGHT AND VEHICLE

A vehicle light optical element assembly of a vehicle lamp, and a vehicle lighting device, a vehicle lamp and a vehicle comprising the vehicle light optical element assembly of the vehicle lamp. The vehicle light optical element assembly comprises a low-beam primary optical element (1), a high-beam primary optical element (2) provided below the low-beam primary optical element (1), and a lens (3) provided on the front end of the low-beam primary optical element (1) and/or the high-beam primary optical element (2), wherein the low-beam primary optical element (1) and/or the high-beam primary optical element (2) are integrated with the lens (3), and the low-beam primary optical element (1) and the high-beam primary optical element (2) are suitable for light convergence and collimation to then pass through the lens (3) to form a low-beam illumination light shape and a high-beam illumination light shape. The vehicle light optical element assembly has the advantages of a compact structure, a small volume, and high assembly accuracy.
