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 fills an interior volume defined by the light-transmissive cover and the printed circuit board.

39. A lighting apparatus comprising:
-
A support surface; a light source comprising at least one light emitting diode (LED) chip, the light source being disposed on the support surface; a phosphor surface comprising phosphor disposed over and spaced apart from the light source, the phosphor configured to perform wavelength conversion of light emitted by the light source; and reflecting surfaces extending between the support surface and phosphor surface; wherein the support surface, the phosphor surface, and the reflecting surfaces are arranged and dimensioned respective to the light source such that most light scattered back from the phosphor surface strikes either the reflecting surfaces or the phosphor surface. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)

52. A lighting apparatus comprising:
-
at least one light emitting diode (LED) chip; and a light mixing chamber including reflecting surfaces defining a light output aperture of the light mixing chamber and a surface comprising phosphor disposed over the light output aperture of the light mixing chamber, the phosphor configured to perform wavelength conversion of light emitted by the at least one LED chip; wherein the at least one LED chip is disposed in the light mixing chamber and is spaced apart from the surface comprising phosphor such that most light scattered in the light mixing chamber strikes either the reflecting surfaces or the surface comprising phosphor. - View Dependent Claims (53, 54, 55, 56, 57)

58. A lighting apparatus comprising:
-
a light source comprising a set of (LED) chips disposed on an electrical interconnect board; a phosphor surface spaced apart from the light source, the phosphor surface comprising phosphor configured to perform wavelength conversion of light emitted by the light source; and reflecting surfaces not comprising phosphor combining with the phosphor surface to surround the set of LEDs. - View Dependent Claims (59, 60, 61, 62, 63)
