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.

Abstract:
In a light emitting package (8), at least one light emitting chip (12, 14, 16, 18) is supported by a board (10). A light transmissive encapsulant (30) is disposed over the at least one light emitting chip and over a footprint area (32) of the board. A light transmissive generally conformal shell (40) is disposed over the encapsulant and has an inner surface (44) spaced apart by an air gap (G) from, and generally conformal with, an outer surface (34) of the encapsulant. At least one phosphor (50) is disposed on or embedded in the conformal shell to output converted light responsive to irradiation by the at least one light emitting chip. A thermally conductive filler material disposed in the generally conformal shell (40) is effective to enhance a thermal conductivity of the composite shell material to a value higher than 0.3 W/(m.K).
Abstract:
A surface mount light emitting package includes a chip carrier having top and bottom principal surfaces. At least one light emitting chip is attached to the top principal surface of the chip carrier. A lead frame attached to the top principal surface of the chip carrier. When surface mounted to an associated support, the bottom principal surface of the chip carrier is in thermal contact with the associated support without the lead frame intervening therebetween.

Abstract:
A light emitting apparatus includes a support having circuitry disposed thereon, at least one light emitting diode (LED) chip mounted on the support and in electrical communication with the circuitry and a reflective layer on the support adjacent the at least one chip.
