Heat dissipation device for LED lamp

An LED lamp comprising:

• a plurality of heat sinks, each of the heat sinks comprising a base plate and a plurality of fins arranged on the base plate;
• a plurality of fin sets each comprising a plurality of flakes and defining a plurality of air passages between the flakes;
• a plurality of LED modules attached a bottom of the base plate of each of the heat sinks;
• and
• a plurality of heat pipes extending through the fin sets and the base plates of the heat sinks and thermally connecting the fin sets and the base plates together, wherein the fin sets and the heat sinks are alternate with each other.

An LED lamp comprising:

• two heat sinks each comprising a base plate with a bottom surface and a top surface, and a plurality of fins extending upwardly from the top surface of the base plate of the each heat sink;
• a fin set located between the heat sinks and comprising a plurality of flakes defining a plurality of passages therebetween;
• a heat pipe extending through the flakes and thermally connecting the fin set and the heat sinks together, wherein air can flow from a place under the fin set to a place above the fin set via the passages;
• and
• a plurality of LED modules attached to the bottom surface of the base plate of the each heat sink, each LED module having a printed circuit board and a plurality of LEDs mounted on the printed circuit board.
