The invention relates to an LED shaping integrated lens. The LED shaping integrated lens is a shaping element integrating primary light distribution and secondary light distribution into a whole; one surface is a refracting surface with focal power and utilized to collect and converge the light of a chip, and the other surface is a diffractive surface and is used for shaping the light output by the chip on the basis of a principle that far-field light spots are redistributed by modulating the phases of light beams so as to obtain output light beams which meet the requirements for usage. The invention has the advantages of simple system composition, level surface, high integration degree, small size, light weight, accurate positioning, convenience for use without secondary optical assembly, capability of obtaining multiple specific functions, and effective prevention of the influence of dust and aerial fog on the property of the LED chip because of good sealing property, and the like.
