Patent ID: 8217409

Claim:
A light emitting diode lamp comprising: a package; at least one light emitting diode disposed within the package; and an encapsulation formed upon the at least one light emitting diode, the encapsulation having: an overall shape defining a non-flat top; surface-texturing formed upon the top; and wherein the overall shape and the surface-texturing are separate features that cooperate to enhance light extraction wherein the encapsulation has a bottom surface that is coplanar with the bottom surface of the light emitting diode, sidewalls that extend above the top surface of the light emitting diode, and the geometric shape of the surface-texturing and the overall shape of the top surface of the encapsulation are both domed and wherein the surface-texturing is configured so that light emitted from the at least one light emitting diode is incident upon a substantial portion of the encapsulation surface at angles that are greater than the critical angle.
