A light emitting structure comprising a substrate 1, a system of wires and at least one LED 6. The wires comprise a laminate of copper sheet and a graphene layer 5 and each wire is in electrical contact with the LED to form an electrical circuit. The substrate may be transparent. The copper layer may also contain another metal, such as nickel and the graphene layer may be a mono-layer of graphene. The device may be constructed such that it does not have a heat sink. The device may comprise more than one LED and these extra LEDs may be arranged in series. The copper graphene laminate wires have improved thermal conduction in comparison with copper wires. The graphene layer may be patterned onto the copper sheet. |
