摘要：A light transforming method and device that includes a lens having one or morespecifically shaped surfaces designed to generate an output image by directing theappropriate amount of electromagnetic energy from a pseudo-collimated beam to the
required regions of the output image for the purpose of recreating the output image. AnLED is collimated to produce the minimum spot size at the projection plane reasonablyachievable and the pseudo-collimated light source impinges on the image shaping lenssurface(s) such that the light is redistributed in correct proportion and angle to generatethe predetermined output image. The image generating surface of the present inventionis defined by a multitude of triangular facets that define a free-form surface shape suchthat when the energy distribution pattern exits the free-form surface the output imageclosely resembles the required output distribution pattern.
