Abstract:
The optics system is a lamp assembly which produces the desired beam pattern by using a reflector, a lens, a retainer lens, and an LED as a light source. The lamp assembly has three main components (the reflector, the lens, and the retainer lens) that maintain proper alignment between the light source and the reflector, the lens, and the retainer lens. The optical system collects substantially 100% of the light from the light source while effectively shaping the beam pattern using both cylindrical and revolved reflector elements. The lens has a saddle-shape which is used with the surface of a revolution to eliminate any “dogbone” light pattern shape. The use of a reflective element forms the foreground of the beam pattern.
