Light emitting diode light bulb and incandescent lamp conversion apparatus
First Claim
1. A light emitting diode (LED) light bulb, comprising:
- a least one LED package mounted on a substrate, the LED package to include an LED die;
at least one thermal conductor coupled to the LED die to transfer heat away from the LED die; and
a thermal transfer contact thermally coupled to the thermal conductor, at least one surface of the thermal transfer contact configured to thermally contact a heat sink external to the LED light bulb.

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.
