LED light bulb with integrated heat sink
An LED lamp includes a lamp housing including an aluminum alloy substantially free of silicone. An electrical circuit trace is disposed on the lamp housing. An LED is attached directly to the lamp housing and electrically connected to the electrical circuit trace. LED driver circuitry is electrically connected to the electrical circuit trace. A housing contains the LED driver circuitry. A threaded incandescent light-type electrical plug may be configured for reception into a standard incandescent light-type socket. The LED driver circuitry is electrically disposed between the electrical plug and the LED. The lamp housing may include a generally frusto-conical shape. A solder mask may be affixed over at least a portion of the electrical circuit trace. The lamp housing may be press formed. The lamp housing is in direct thermal conductive relation to the LED such that heat energy is dissipated from the LED directly to the lamp housing.
