Abstract:
1. A light emitting diode (LED) package comprising: a die pad having a bottom surface and an upper surface, the upper surface having a centrally located recessed cavity with a chip attach surface disposed between the bottom surface and the upper surface of the die pad, the recessed cavity having sidewalls that extend upward and outward from the chip attach surface to the upper surface of the die pad so that a circumference along a junction where the sidewalls intersect the chip attach surface is less than a circumference along a junction where the sidewalls intersect the upper surface of the die pad; leads arranged on opposing sides of the die pad, the leads having bottom surfaces that are substantially coplanar with the bottom surface of the die pad and upper surfaces that are substantially coplanar with the upper surface of the die pad; an LED chip coupled to the chip attach surface within the recessed cavity, the LED chip having bonding pads located on an upper surface thereof; conductors that electrically connect the bonding pads to the leads; and a package body comprising an encapsulant, wherein the encapsulant fills a space between the die pad and the leads to form a bottom encapsulant surface that is substantially coplanar with the bottom surface of the die pad and the bottom surfaces of the leads, and wherein the encapsulant covers the LED chip within the recessed cavity and forms a lens over the LED chip.
