ABSTRACT:
An LED illumination device includes a lampshade and a light engine arranged on the lampshade. The lampshade defines a room therein. The light engine includes a heat dissipation member, and a plurality of LEDs arranged on the heat dissipation member and received in the room of the lampshade. The heat dissipation member includes a heat pipe and a heat sink. The heat pipe forms a planar absorbing surface and a dissipating surface opposite to the absorbing surface. The absorbing surface of the heat pipe attaches to the LEDs to absorb heat therefrom. The heat sink includes a base attaching to the dissipating surface of the heat pipe to absorb heat of the heat pipe, and a plurality of fins extending from the base for dissipating heat absorbed from the heat pipe.
