Semiconductor light source
A light source may comprise a thermally conductive frame comprising a base and a faceted portion extending from the base. The faceted portion may comprise a plurality of facets spaced circumferentially thereabout. Additionally, a hollow passageway may extend through the base and axially through the faceted portion. A plurality of LED chips may be arranged on the plurality of facets to provide an emission of light in an arc of 360 degrees.
