摘要: A lens comprises an incident curved surface and exit opposite to the surface. The are configured such that light emitted from a emitting diode (LED) source enters through on surface, is refracted by position of point represented z=z 0 −√{square root over (r 2 −(x +y ))}+ax +by +cx y , where x, z respective coordinates along X, Y Z axes, parameters a, b, c, r numbers determining shape axis coincides with optical lens.
