ABSTRACT:
A method of manufacturing an electrically driven L.E.D. lamp assembly (10) comprising the steps of screen printing an electrically insulating coating (16) which can be of less than two hundred microns thickness over an electrically and thermally conductive heat sink, i.e., aluminum, and printing circuit traces 18 of a resin with metal dispersed therein in end to end relationship on the routes of insulating coating 16 to establish discrete and electrically conductive paths for electrically interconnecting light emitting diodes 20. The light emitting diodes 20 are adhesively secured to the ends of adjacent circuit traces 18 with an electrically conductive adhesive 26 comprising an organic polymeric material compounded with a metal.
