The invention belongs to the field of optical lenses, and particularly relates to a one-step packaging LED (Light Emitting Diode) lens with a free curve and a design method of the same. The lens comprises a plane and the free curve, wherein the plane corresponds to an inner surface, and the free curve corresponds to an outer surface and is used for realizing uniform illumination and rectangular light distribution.
