LIGHT EMITTING DIODE LIGHT BULB AND INCANDESCENT LAMP CONVERSION APPARATUS

摘要

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 (100) includes a thermal path from LED dies (111) to a thermal transfer contact (115) having an externally available surface. The LED light bulb (100) and an incandescent lamp adapter (500) are consumer-installable in an incandescent lamp. A heat spreader component (520) of the lamp adapter (500) contacts the thermal transfer contact (115) of the LED light bulb (100) to dissipate heat originating at the LED dies (111). 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 (100). A lock-in safety device prevents retraction of the lamp cord plug from the LED power supply once inserted.
