Abstract:
This paper describes a new headlamp design evaluation and simulation program that provides greater freedom and improved efficiency in light distribution design, using either concave or convex lens and a reflector with a NURBS (Non-Uniform Rational B-Spline Surface), for one of its free surfaces. It also offers simulation results of light distribution designs using this program in order to produce various headlamps, including high-efficiency and flat headlamps, each with a concave lens, and a thin headlamp with a convex lens.
