Method to optimize micro-optic lens in LED flashlight application
A micro-optic lens is disclosed. The micro-optic lens includes a substrate; and a lens element on the substrate, wherein the lens element includes a flat surface and an annularly grooved surface including first facets and second facets, and wherein the first facets collimate a light effectively and the second facets are parallel to a light. The micro-optic lens can decrease the draft loss and collimate the emitted light beams to increase the light efficiency. Further, the present invention also provides a method for designing angles of micro-optic lenses.
