Abstract

An LED lighting device for use in and powered through an incandescent light bulb alternating current socket is provided. The lighting device includes an LED light, a regulation circuit and a base. The regulation circuit converts an alternating current input to a direct current output. The base is adapted to fit within an incandescent light bulb alternating current socket. In addition to the LED light, regulation circuit and base, the invention can further include a heat sink that removes heat from the LED light, regulation circuit and combinations thereof. Preferably the heat sink is a ceramic. In addition, the regulation circuit can be a printed circuit that is printed directly onto the ceramic heat sink. The LED light, regulation circuit, base, and ceramic heat sink take the form of a lighting device that is exchangeable with an incandescent light bulb in traditional lighting fixtures.
