ABSTRACT:
An optical light engine is fabricated by providing a thermally conductive base having one or more mounting pedestals for elevating one or more LED die above the base's surface. The LED die are mounted on the pedestals, electrically connected, and a mold having a molding surface for molding a dome centered around the LED die is disposed on the base over the pedestal-mounted LED die. The encapsulating material is then injected through an input port disposed in the base to mold the dome around the LED die. The encapsulant material is cured and the mold is removed. In an advantageous embodiment, the light engine comprises a ceramic-coated metal base made by the low temperature co-fired ceramic-on-metal process (LTCC-M).
