Abstract
An LED lamp includes a light source including LEDs and a heat dissipation device. The heat dissipation device includes a heat absorption board contacting the light source to absorb heat generated by the LEDs, a fin assembly located over the heat absorption board, two heat pipes thermally connecting the heat absorption board and the fin assembly, a fan and a fan holder fixing the fan on the fin assembly. The fan holder includes a supporting board supporting the fan and supporting posts connecting an outer edge of the heat dissipation board and an outer edge of the supporting board. The supporting posts are embedded in the fin assembly.
