Application of Free Formed Surface Reflectors

In the 1992 SAE Technology Convention the authors reported a free formed surface reflector capable of sharp-cut illumination by adding a wavy shape to a paraparaboloid reflector consisting of different horizontal and vertical parabolas. Using this reflector, it has become possible to produce headlamps having inclined lens shapes and reduced lamp heights. However, headlamps are required to look more attractive and balanced with the vehicle body design, in addition to improving their photometric performance. In the present study, the authors investigated new free formed surface reflectors providing higher freedom in headlamp design to meet the recent market needs.
