  • Patent number: 8920002
    Abstract: A lead frame for a light-emitting diode (LED). The lead frame includes a first lead and a second lead. Each lead includes a top portion and an integrated wire-clasping portion. The first and second top portions each angle away from the center of the lead frame to form an increasingly larger gap between the two leads. The wire-clasping portions of each lead initially lie in a common plane and are adjacent one another. After securing the wire to the wire-clasping portions of the lead frame, the leads of the lead frame are rotated or twisted approximately 90 degrees such that the wire-clasping portions of the leads are opposite one another, rather than lying in the same plane. The wires and attached lead frame are inserted into a lampholder, the lampholder recesses receiving the top tabs of the lead frame and holding the wires and lead frame in place.
