Abstract
A method of manufacturing an array of light emitting diodes in which a first insulating sheet carrying a first set of mutually isolated conductors is bonded to a sheet of thermally conductive material, a second, perforated, sheet carrying a second set of mutually isolated conductors is bonded to the first insulating sheet with the perforations overlying the conductors of the first sheet and the two sets of conductors crossing one another, light emitting diodes are placed in the perforations to contact each with one electrode a conductor of the first set and the other electrode of each diode is electrically connected to a conductor of the second set.
