Abstract: In various embodiments, an asymmetric optical lens (100) may include a proximal volume (102). The proximal volume may include a base surface (106) and an LED recess (108) shaped to receive light emitted by one or more LEDs (109) along a first central light output axis (112). The LED recess may guide the received light along a second central light output axis (110) that is at a first angle (?) relative to the first central light output axis. The asymmetric optical lens may also include a distal volume (104) that includes, opposite the base surface, a non-planar light emission surface (114). The distal volume may be shaped to guide light from the proximal portion through the light emission surface along a third central light output axis (116) that is at a second angle (?) to the first central light output axis. The second angle may be greater than the first.

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.
