Patent ID: 8446081

Claim:
A heat dissipation device for a LED lamp, comprising: an upper piece having a plurality of first, second, and third plug holes wherein the second plug holes are aligned with a portion of the first plug holes, and these first and second plug holes are connected by separate conductive layers; the other first plug holes are also aligned and connected by separate conductive layers; the third plug holes are adjacent to the second plug holes and each third plug hole is configured on an individual conductive layer; at least a lower piece having a plurality of fourth plug holes, each corresponding to a first plug hole on the upper piece 1 wherein the fourth plug holes are aligned and connected by separate conductive layers; a plurality of sleeves sandwiched between the upper and lower pieces and the two ends of each sleeve are against the upper and lower pieces; a plurality of LEDs, each having leads of appropriate length threaded through the first plug holes, a sleeve, and the fourth plug holes, and soldered to the corresponding conductive layers of the upper and lower pieces, respectively; and a plurality of heat dissipation elements having the ends threaded through the second and third plug holes and soldered to the corresponding conductive layers of the upper piece; wherein, when the LEDs are turned on, the heat produced by the LEDs is dissipated through the leads which are reserved for an appropriate length, the conductive layers on the upper and lower pieces which have extended areas, and the heat dissipation elements among the LEDs.
