Abstract:
1. A light emitting solid state lamp comprising: a light emitting diode (LED) that emits photons having frequencies selected from the group consisting of the ultraviolet, violet and blue portions of the electromagnetic spectrum, an encapsulant, and a header; said LED comprising a Group III nitride active portion for generating desired frequency photons under the application of current across said LED, wherein said LED is vertically oriented; said header comprising a reflective cup for supporting said LED and for providing electrical contact to said diode LED and to said active portion; an ohmic contact to said LED with said ohmic contact being in electrical and direct physical contact with said header; said encapsulant comprising a phosphor, said encapsulant comprising a plurality of portions wherein said phosphor is present in at least one of said portions of said encapsulant that emits responsive frequencies in the yellow portion of the visible spectrum when excited by frequencies emitted from the group consisting of the ultraviolet, violet and blue portions of the electromagnetic spectrum emitted by said LED, wherein a substantially transparent first portion of said encapsulant partially fills said reflective cup and covers said LED and a second portion of said encapsulant comprises said phosphor and is on said first portion.
