Abstract
An LED lighting device comprising an integral body comprising a dielectric thermally conductive polymer has an electrically conductive material directly attached to, or at least in part is molded within the body and forms a circuit pattern. Two or more LED die each having at least a portion thereof being attached directly either to one of a portion of the first body for direct thermal conduction or a portion of the electrically conductive material for direct electrical and thermal conduction or both. The integral body is optionally molded to have integral cooling surfaces such as fins. The integral body also may take a shape conforming to a mounting structure of a lighting fixture and may also include thereon additional electrical components for assisting the LED die in producing light, in other words drive components. Terminals may be integrally molded or formed in the body upon which a portion of the conductive material resides for electrical connection to another device such as a power source.
