▎ 摘　　要

NOVELTY - Heat conducting composite material comprises: a matrix; and many graphene sheets respectively having a two-dimensional planar structure, where a basal plane of each of the graphene sheets has a lateral size of 0.1-100 nm, and comprises a quantum well structure. USE - The heat conducting composite material is useful in a thermal garment, a solar microwave water purifier, an infrared paint and LED (all claimed). ADVANTAGE - The heat conducting composite material: provides high radiating efficiency and heat dissipation effect without affecting the light extraction rate of LED; utilizes the graphene sheets having a high degree of graphitization; and provides the infrared paint material exhibiting improved thermal storage or high temperature resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an LED comprising: an insulating substrate (11); a chip (12) disposed on the insulating substrate; a conducting wire frame clamped between the insulating substrate and the chip; a conducting wire (14) having one end connected to the chip, and one other end connected to the wire conducting frame; and a transparent package material (15) as the heat conducting composite material covering on the insulating substrate. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of the LED. Insulating substrate (11) Chip (12) Conducting wire frame (13) Conducting wire (14) Transparent package material (15)
