Abstract:
1. A semiconductor light source for illuminating a physical space comprising a lead frame having at least two electrodes, one being a cathode and another being an anode, the lead frame further comprising: a. a cylindrical electrode, made of a heat conductive material, having a closed first end upon which an electrical connection is attached, b. a second electrode, insertable within the cylindrical electrode, said second electrode having an upper portion with a diameter sufficient to prevent full insertion into the cylindrical electrode and an electrical connection; c. electrical insulation between the cylindrical electrode and said second electrode, thereby electrically isolating said cylindrical electrode from said second electrode; d. a plurality of facets located on said cylindrical electrode, said facets being configured to accept mounting of light emitting semiconductor chips thereon; and e. a plurality of light emitting semiconductor chips mounted on said facets of said cylindrical electrode and connected electrically to said cylindrical electrode and said second electrode.
