ABSTRACT:
Phosphor layer arrangement for use with light emitting diodes. In an aspect, a light emitting diode apparatus is provided that includes a least one light emitting diode, an encapsulation covering the at least one light emitting diode, a lens having a phosphor layer formed upon a bottom surface, the lens positioned to cover at least part of the encapsulation, and an air gap between the phosphor layer and the encapsulation. In an aspect, a light emitting diode lamp is provided that includes a package, a least one light emitting diode, an encapsulation covering the at least one light emitting diode, a lens having a phosphor layer formed upon a bottom surface, wherein the lens is positioned to cover at least part of the encapsulation, and an air gap between the phosphor layer and the encapsulation.
