Abstract：
 The 3D optical lens design method comprises: based on law of conservation of energy, dividing out some sub-areas as the light source energy equal to illuminant plane energy; selecting one point any of the point in one emergence line and corresponding equal-energy illuminant plane points as the initial point for target lens; iterative solving coordinate and normal vector for every discrete point to determine the lens surface. Compared with prior art, this invention is convenient and high efficient, and can save energy for wide application.
