1. A lamp comprising:
- an optically transmissive enclosure connected to a base to define an interior space;
an LED array disposed in the optically transmissive enclosure operable to emit light when energized through an electrical connection;
a gas contained in the enclosure to provide thermal coupling to the LED array; and
a heat sink structure thermally coupled to the LED array for transmitting heat from the LED array to the enclosure primarily through the gas, wherein the heat sink structure is positioned entirely inside of the enclosure and spaced from the base such that the heat sink structure is supported in the interior space at a distance from the enclosure of less than 8 mm.

10. A lamp comprising:
-
an optically transmissive enclosure; an LED array disposed in the optically transmissive enclosure to be operable to emit light when energized through an electrical connection; a gas contained in the enclosure to provide thermal coupling to the LED array; and a heat sink structure thermally coupled to the LED array for transmitting heat from the LED array to the gas, where the heat sink structure comprises an outside surface that supports the LED array and faces the enclosure and an inside surface that faces away from the enclosure where the inside surface and the outside surface are surrounded by the gas.
