Abstract:
1. A lighting package comprising: at least one light emitting chip; a board supporting the at least one light emitting chip; a light-transmissive encapsulant disposed over the at least one light emitting chip and over a footprint area of the board; a light-transmissive generally conformal shell disposed over the light-transmissive encapsulant and having an inner surface spaced apart by an air gap from and generally conformal with an outer surface of the light-transmissive encapsulant; and a phosphor disposed on or embedded in the conformal shell and configured to output converted light responsive to irradiation by the at least one light emitting chip; wherein the light-transmissive encapsulant and conformal shell are generally hemispherical and the footprint area of the board is generally circular with a radius about equal to a radius of the hemispherical light-transmissive encapsulant and the air gap between the outer surface of the light-transmissive encapsulant and the inner surface of the conformal shell is at least about 0.5 millimeter.
