摘要:
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.

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 some embodiments, the LEDs can be mounted on or fixed to a light transmissive submount. In some embodiments, LEDs can be disposed on both sides of a two-sided submount, or on thee or more sides if the submount structure includes three or more mounting surfaces. 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 gas is at a pressure of from about 0.5 to about 10 atmospheres and has a thermal conductivity of at least about 60 mW/m-K.

A semiconductor light emitting apparatus includes an elongated hollow wavelength conversion tube that comprises an elongated wavelength conversion tube wall having wavelength conversion material such as phosphor dispersed therein uniformly or non-uniformly. The tube need not be cylindrical. A semiconductor light emitting device is oriented to emit light inside the elongated hollow wavelength conversion tube to impinge upon the elongated wavelength conversion tube wall and the wavelength conversion material dispersed therein.
