Patent ID: 8803183

Claim:
A light-emitting diode (LED) apparatus comprising: a heat-conducting substrate having a plurality of heat-conducting wires and an insulating material, said insulating material selected from the group consisting of a thermoplastic resin and a thermoset resin, said insulating material filling in gaps between said plurality of heat-conducting wires, said heat-conducting substrate baying a front face and a rear face, said plurality of heat-conducting wires being in spaced relation to each other and extending outwardly of said front and rear face of said heat-conducting substrate, said plurality of heat-conducting wires being segregated from each other by said insulating material after said insulating material has cured; at least one LED unit affixed onto said front face of said heat-conducting substrate, the LED unit having an LED and a pair of electrode pins and a heat sink; a pair of electrode pads formed of a conductive material and spaced from each other, each of said pair of electrode pads being planar and affixed onto said front face of said heat-conducting substrate, said pair of electrode pads being respectively connected to said pair of electrode pins of said LED unit; an insulating layer affixed onto said rear face of said heat-conducting substrate, said insulating layer positioned in a location in correspondence to a location of the electrode pad; and a heat-conducting pad formed of a heat-conducting material, said heat-conducting pad being separate from and spaced from said electrode pads, said heat-conducting pad positioned on adjacent said front face of said heat-conducting substrate, said heat-conducting pad being in contact with said heat sink of the LED unit so as to conduct heat therefrom.
