Abstract:
In one embodiment, a lamp comprises an optically transmissive enclosure. An LED array is disposed in the optically transmissive enclosure operable to emit light when energized through an electrical connection. A gas is contained in the enclosure to provide thermal coupling to the LED array. The gas may include oxygen.
Abstract:
A lamp has an optically transmissive enclosure and a base defining a longitudinal axis of the lamp that extends from the base to the free end of the enclosure. An LED assembly is positioned in the optically transmissive enclosure. The LED assembly includes LEDs operable to emit light when energized through an electrical path from the base. The LED assembly is arranged such that the plurality of LEDs face perpendicularly to the longitudinal axis of the lamp. The emission profile of the LEDs being at least 120 degrees FWHM.

In one embodiment, a lamp comprises an optically transmissive enclosure. An LED array is disposed in the optically transmissive enclosure operable to emit light when energized through an electrical connection. A gas is contained in the enclosure to provide thermal coupling to the LED array. A board supports lamp electronics for the lamp and is located in the enclosure. The LED array is mounted to the board and LEDs are mounted on a submount formed to have a three dimensional shape. The board is electrically coupled to the LED array and the submount may be thermally coupled to the gas for dissipating heat from the plurality of LEDs.

Abstract:
A lamp has an optically transmissive enclosure and a base. A tower extends from the base into the enclosure and supports an LED assembly in the enclosure. The LED assembly comprises a plurality of LEDs operable to emit light when energized through an electrical path from the base. The tower and the LED assembly are arranged such that the plurality of LEDs are disposed about the periphery of the tower in a band and face outwardly toward the enclosure to create a source of the light that appears as a glowing filament. The tower forms part of a heat sink that transmits heat from the LED assembly to the ambient environment. The LED assembly has a three-dimensional shape. An electrical interconnect connects a conductor to the heat sink where the conductor is in the electrical path between the LED assembly and the base.
