LED lamp and method of making the same

A lamp comprising:

• a heat sink with a plurality of fins and facets, the facets arranged around a central axis and facing outwardly from the central axis, each of the fins placed between adjacent ones of the facets and extending outwardly from the central axis;
• a plurality of circuit boards, each one of the circuit boards mounted on a respective facet, each one of the circuit boards including an array of semiconductor emitters thereon;
• a light diffusing housing covering each of the facets and exposing the fins;
• a power conversion module in communication with the semiconductor emitters;
• and
• a power connector in communication with the power conversion module.

A method for making a lamp, the method comprising:

• providing a heat sink, the heat sink comprising a plurality of fins and facets, the facets arranged around a central axis and facing outwardly from the central axis, each of the fins placed between adjacent ones of the facets and extending outwardly from the central axis;
• disposing a plurality of circuit boards on the plurality of facets, each of the circuit boards including an array of semiconductor emitters;
• electrically connecting the semiconductor emitters to a power conversion device;
• enclosing the facets with a light diffusing housing;
• and
• coupling a power connector to the heat sink and electrically connecting the power connector to the power conversion device.
