Title:
LIGHT EMITTING DIODE LIGHT BULB AND INCANDESCENT LAMP CONVERSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/119063
Kind Code:
A3
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 (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.
