LED lighting systems are becoming more predominant as substitutes for older lighting systems. LED systems are an example of solid-state lighting (SSL) and have advantages over older lighting solutions such as incandescent and fluorescent lighting because they use less energy, are more durable, operate longer, and can be combined in multi-color arrays that can be controlled to deliver virtually any color light, and generally contain no lead or mercury. A solid-state lighting system may take the form of a lighting unit, light fixture, light bulb, or a “lamp. , the invention comprises an optically transmissive enclosure. An LED array is willing 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 heat sink structure is thermally coupled to the LED array for transmitting heat from the LED array to the gas. The heat sink structure is at a distance from the enclosure of less than 8 mm.
