This report describes the development of an advanced technology headlamp reflector which is capable of producing a sharp cut-off line. Similar attempts in the past have suffered from various drawbacks, but through the use of a mathematically derived set of equations describing a controlled curved surface, we were able to greatly increase performance specifications. Prototype headlamp tests showed improved distant visibility, a major problem in existing designs. Furthermore, by superimposing a ripple pattern onto the reflector surface, we were able to attain sufficient light diffusion to enable the reflector to be used within headlamps having highly slanted outer lenses.
