Abstract:
An automotive headlamp that utilizes a lightguide to form light into a desired output shape and illumination pattern. The headlamp is comprised of a light emitting source, and a lightguide. The lightguide is able to create a hot spot, and a horizontal cut-off in the illumination pattern. The cut-off is formed at the exit face of the lightguide. A cut-off facet angled from the exit-face of the lightguide is used to help with obtaining a sharp cut-off.
