Semiconductor light source for illuminating a physical space including a 3-dimensional lead frame
View Patent ↗The present invention is a semiconductor light source 100 for illuminating physical spaces including a lead frame with multiple facets 101 . Each facet can have one or more semiconductor light emitting devices 108 , such as LEDs, located on it. The light source is disclosed in threaded 100 , surface mounted 400 , and bar light 700 configurations.
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.
2. A semi-conductor light source as recited in claim 1 wherein said cylindrical electrode and said second electrode are configured with respect to each other to form a bar light.
3. A semi-conductor light source as recited in claim 2 further comprising an encapsulation structure over said bar light.
4. A semi-conductor light source as recited in claim 1 further comprising at least one other lead frame with a plurality of facets in operable connection to the lead frame and having at least one LED chip on at least one facet.
