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.
Claims32
A lamp comprising:
- an optically transmissive enclosure;
- 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 gas.
2 more elements
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, the LED array being thermally coupled to the enclosure;
- and
- a base forming part of the electrical connection to the LED assembly comprising an upper part that is connected to enclosure and a lower part that is joined to the upper part.
1 more element
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 wherein the electrical connection comprises a thermally resistive electrical path that prevents overtemperature of the LED array, the LED array being mounted on an LED assembly comprising a heat sink structure where the LED array is positioned substantially in the center of the enclosure;
- a gas contained in the enclosure to provide thermal coupling to the LED array.
