1. A lighting apparatus comprising:
- a light source selected from a group consisting of (i) a single light emitting diode (LED) chip and (ii) a plurality of LED chips facing a same direction; and
a spherical surface spaced apart from and surrounding the light source, the spherical surface comprising phosphor configured to perform wavelength conversion of light emitted by the light source.

Abstract
In a lighting package, a printed circuit board supports at least one light emitting die. A light transmissive cover is disposed over the at least one light emitting die. A phosphor is disposed on or inside of the light transmissive dome-shaped cover. The phosphor outputs converted light responsive to irradiation by the at least one light emitting die. An encapsulant substantially tills an interior volume defined by the light-transmissive cover and the printed circuit board.
