    摘要: 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).

    摘要: A packaging method comprises: forming a circuit board by forming a substantially continuous conductive layer on an insulating board and removing selected portions of the continuous conductive layer to define an electrically conductive trace; laser cutting the electrically conductive trace to define sub-traces electrically isolated from each other by a laser-cut gap formed by the laser cutting; and bonding a light emitting diode (LED) chip to the circuit board across or adjacent to the laser-cut gap, the bonding including operatively electrically connecting an electrode of the LED chip to one of the sub-traces without using an interposed submount. A semiconductor package comprises an LED chip flip-chip bonded to sub-traces of an electrically conductive trace of a circuit board, the sub-traces being electrically isolated from each other by a narrow gap of less than or about 100 microns.
