Patent ID: 8723212

Claim:
A semiconductor light source, comprising: an electrically and thermally conductive outer lead frame, the outer lead frame comprising: a first end having a plurality of facets; a second end spaced from the first end and configured for mating with an electrical socket; and a hollow passageway extending through the outer lead frame, the hollow passageway having a first opening in the first end and a second opening in the second end; an electrically conductive inner lead frame, the inner lead frame comprising: a shaft having a first end and a second end spaced from the first end, the shaft extending through the hollow passageway of the outer lead frame, and a cap attached to the first end of the shaft; an insulation layer electrically isolating the inner lead frame from the outer lead frame; and a semiconducting LED chip positioned on at least one facet of the plurality of facets, the semiconducting LED chip in electrical communication with the cap and in electrical communication with the outer lead frame.
