| Title: |
Light Emitting Diodes Packaged For High Temperature Operation |
| Abstract: |
In accordance with the invention, an LED packaged for high temperature
operation comprises a metal base including an underlying thermal
connection pad and a pair of electrical connection pads, an overlying
ceramic layer, and a LED die mounted overlying the metal base. The LED is
thermally coupled through the metal base to the thermal connection pad,
and the electrodes are electrically connected to the underlying
electrical connection pads. A low thermal resistance insulating layer can
electrically insulate other areas of die from the base while permitting
heat passage. Heat flow can be enhanced by thermal vias to the thermal
connector pad. Ceramic layers formed overlying the base can add circuitry
and assist in distributing emitted light. The novel package can operate
at temperatures as high as 250.degree. C.
