Abstract

The embodiments of the invention provide a multi-focal collimating lens and a bi-function headlight assembly. With the relative positions referring to the mounting position of the multi-focal collimating lens within the bi-function headlight assembly, the multi-focal collimating lens includes a lower collimating lens part and an upper collimating lens part located on top of the lower collimating lens part. One focal point of the lower collimating lens part is located on a vertical symmetry plane of the lower collimating lens part, and two focal points of the upper collimating lens part are symmetrically located on both sides of a vertical symmetry plane of the upper collimating lens part, so that a cut-off line of a low beam can be generated in a far-field light pattern of the multi-focal collimating lens.
