High power LED heat radiating device

The utility model discloses a big-power LED heat dissipation device, which comprises a big-power LED and a heat dissipater. The big-power LED is fixed on one end of the heat dissipater. A seal and vacuum heat pipe is formed in the interior of the heat dissipater directly. The utility model has the advantages of dissipating heat effectively by utilizing the least space, reducing the temperature of the luminous diode, slowing the light decay of the big-power LED, improving the stability and the working life of the big-power LED greatly.
