An LED with a honeycomb radiating heat dissipation device includes a sapphire substrate, an LED epitaxy layer on the sapphire substrate, a thermally conductive binding layer, an intermediate heat dissipation layer, a base substrate and a honeycomb-like heat dissipation device. The thermally conductive binding layer is provided to bind the sapphire substrate and the intermediate heat dissipation layer. The honeycomb-like heat dissipation device is in contact with the base substrate and includes a heat dissipation body and holes, each having a sidewall covered with a thermally radiative heat dissipation film. The intermediate heat dissipation layer and the thermally radiative heat dissipation film is made from a mixture of metal and nonmetal and has a microscopic surface structure with specific crystal, so as to provide high efficiency of heat dissipation by thermal radiation. |
