  • Gas cooled LED lamp with heat conductive submount
    Patent number: 9322543
    Abstract: A gas cooled LED lamp and submount is disclosed. The centralized nature of the LEDs allows the LEDs to be configured near the central portion of the optical envelope of the lamp. In example embodiments, the LEDs can be cooled and/or cushioned by a gas in thermal communication with the LED array to enable the LEDs to maintain an appropriate operating temperature for efficient operation and long life. In some embodiments, the LED assembly is mounted on a glass stem. In some embodiments a thermal resistant path is created that prevents overtemperature of the LED array during the making of the lamp. In some embodiments the LED assembly comprises a lead frame and/or metal core board that is bent into a three-dimensional shape to create a desired light pattern in the enclosure or an extruded submount formed into a three-dimensional shape.
