Multi B-Spline Surface Reflector Optimized with Neural Network

A system has been completed that makes it possible to design headlamps having an ideal light distribution pattern. Using multi B-spline surfaces (MBSS) for the reflector, the shape and the light distribution pattern it generates are computer-simulated. The characteristics of the light distribution are analyzed, and using a neural network the reflector is partitioned. Each surface is continuously modified so as to obtain the optimum light distribution pattern.
