More Information
Summary:A light source for an image projection system comprises one or more LEDs packaged for high temperature operation. The LED die are disposed on a package comprising a ceramic coated metal base including one or more underlying thermal connection pads, and underlying electrical connection pads, each LED die thermally coupled through the metal base to a thermal connection pad and electrically coupled to electrical connection pads. Arrays of LED die are fabricated by the low temperature co-fired ceramic-on-metal technique (LTTC-M). The LEDs are mounted in an array of cavities having tapered sides to reflect light from the LEDs.
