Abstract

An LED lamp includes a thermally conductive base including an appendage protruding from a center of a first end and an opening to cavity on a second end. The appendage includes a channel coupled to the cavity. The LED lamp further includes an LED assembly disposed at an end of the protruding appendage and in thermal communication with the base. The LED assembly further includes a bulb disposed on the first end, wherein the appendage protrudes in a direction towards the center of the bulb, and wherein the LED assembly is proximate to the center of the bulb. The LED assembly further includes an electrical housing, configured to house an electrical module, disposed inside the cavity of the base. An electrical wire disposed inside the channel electrically couples the LED assembly to the electrical module.
