Abstract
A vehicle headlamp includes a beamforming waveguide having an input face, an output face, and a guide portion extending between the input face and the output face. A light source is positioned at the input face of the beamforming waveguide. A lens is positioned at the output face so that light output by the beamforming waveguide passes through the lens to provide vehicle forward illumination. The beamforming waveguide is shaped to generate a desired headlamp beam pattern and can be formed as a block of solid material, a bundle of plastic or glass fibers, or a solid molded wedge that can be moved between two positions to provide both high and low beam forward illumination.
