ACRs (All Clear Reflectors), also widely referred to as FFRs (Free Form Reflectors), were designed in general and intelligent ways using a NURBS surface for the mathematical modeling of the reflector shape and artificial intelligence as the optimum design algorithm. An ACR, which consists of a continuous surface reflector and clear outer lens, offers styling advantages and provides a high quality light performance. The clear outer lens of an ACR remains efficient even with a highly inclined shape, as in the design of a sports car, plus the complete clearness of the reflector surface eliminates the nuisance of stray light caused by the steps between individual segments of multi-faced reflectors. The design technique of an ACR was also successfully applied and tested with all types of lamps, including low beams, high beams, fog lamps, and turn signal lamps.
