A lighting module is provided that includes a single-piece lens having an input surface including a plurality of near-field lens elements, and an exit surface, each element having a different focal length. The lighting module also includes light-emitting diode (LED) source positioned to direct incident light through the input surface. Further, the elements are configured to shape the light from the input surface into a collimated light pattern emanating from the exit surface containing at least 60% of the incident light.
