Abstract: The present invention is designed to overcome the problems with MCPCB technology, which includes conductive solid body, typically copper or aluminum, typically having rods extending therefrom. This conductive solid body is fastened in place by a body constructed of typically plastic/Delrin® that the copper rods may be pressed or installed into. This body may be conductive or non-conductive. Each LED is mounted to a standard printed circuit board (PCB) or flexible circuit board that contains through holes large enough to fit the metal bottom of the LED through the hole far enough for the LED to make contact with the face of the solid body. Typically, board thickness of 0.032? or less is required for this to work effectively. The LED is glued to the face solid body via a thermally conductive, electrically neutral adhesive. The LED may also be adhered via thermal tape, thermal pad, or held against the solid body via its solder joints where no bonding of the LED is required.
