Abstract
Apparatus and methods separate the functions of light emission, heat dissipation, and power conversion in LED lighting. Doing so may facilitate cost-effective LED lighting and enable the conversion of existing incandescent lamps to LED service. An LED light bulb includes a thermal path from LED dies to a thermal transfer contact having an externally available surface. The LED light bulb and an incandescent lamp adapter are consumer-installable in an incandescent lamp. A heat spreader component of the lamp adapter contacts the thermal transfer contact of the LED light bulb to dissipate heat originating at the LED dies. A lamp adaptable LED power supply plugs into a standard AC power outlet and includes a receptacle to accept insertion of a lamp cord plug to deliver power to the LED light bulb. A lock-in safety device prevents retraction of the lamp cord plug from the LED power supply once inserted.
