ABSTRACT:
Surface-textured encapsulations for use with light emitting diodes. In an aspect, a light emitting diode apparatus is provided that includes a light emitting diode, and an encapsulation formed upon the light emitting diode and having a surface texture configured to extract light. In an aspect, a method includes encapsulating a light emitting diode with an encapsulation having a surface texture configured to extract light. In an aspect, a light emitting diode lamp is provided that includes a package, at least one light emitting diode disposed within the package, and an encapsulation formed upon the at least one light emitting diode having a surface texture configured to extract light. In another aspect, a method includes determining one or more regions of an encapsulation, the encapsulation configured to cover a light emitting diode, and surface-texturing each region of the encapsulation with one or more geometric features that are configured to extract light.
