Abstract
A system and method for exterior projection lighting of a vehicle include a generally ellipsoidal faceted reflector disposed on a rear side of a projection lens. First and second focal points of each facet define corresponding reflector focal regions. A semi-conducting light source positioned at an acute angle, such as a single light emitting diode (LED) without a primary optic, emits light toward the reflector from within the first reflector focal region. Reflected light passes through the projection lens to illuminate a desired beam pattern. A curved shade disposed between the projection lens and the light source has at least a portion of a top edge disposed within the second reflector focal region. The shade blocks a portion of reflected light from extending below the optical axis.
