Abstract

See full text

A light emitting diode (LED) with a micro-structure lens includes a LED die and a micro-structure lens. The micro-structure lens includes a convex lens portion, at least one concentric ridge structure surrounding the convex lens portion, and a lower portion below the convex lens portion and the at least one concentric ridge structure. The lower portion is arranged to be disposed over the LED die. A first optical path length from an edge of the LED die to a top center of the microstructure lens is substantially the same as a second optical path length from the edge of the LED die to a side of the micro-structure lens.
