Patent ID: 7196459

Claim:
A light emitting assembly comprising a metal substrate providing an inorganic electrically insulating coating less than one thousand microns thickness; a plurality of circuit traces fired and thereby bonded to the inorganic electrically insulating coating providing terminals and conductive paths for placing light emitting elements in circuit, the terminals being of a composition compatible with metal droplet connections, the circuit traces having therein an inorganic dielectric material and a metal; a plurality of light emitting elements having leads bonded to the terminals with metal droplets and providing a thermally conductive base having a flat section of predetermined area; and a solderable thermal conductor, having therein an inorganic dielectric material and a metal, fired and thereby bonded to the inorganic insulating coating, the thermal conductor being spaced from and electrically isolated from the circuit traces, the flat section of the base of at least some of the light emitting elements being in intimate heat exchange relation with the thermal conductor and thereby in conductive heat transmitting relation with the substrate.
