Abstract
A light-guiding pillar used in a vehicle lamp includes a major structure and a light-guiding structure. The major structure has a light incident surface, a light outgoing surface, an upper surface, and a bottom surface. The upper surface and the bottom surface are disposed between the light incident surface and the light outgoing surface, in which the upper surface and the bottom surface are opposite to each other. The major structure is configured to guide a portion of a light beam entering the major structure through the light incident surface to the light caving surface. The light-guiding structure is disposed on the upper surface and configured to guide another portion of the light beam entering the major structure through the light incident surface from the upper surface to the bottom surface with passing through the bottom surface.
