An LED lamp includes a lamp seat, a prism-shaped first heat sink disposed on a top of the lamp seat, a second heat sink covering a top of the first heat sink, a plurality of heat pipes thermally connecting the first heat sink with the second heat sink, a plurality of LED modules mounted on the first heat sink and an envelope located between the lamp seat and the second heat sink and surrounding the first heat sink. The first heat sink includes an annular base and a plurality of first fins and second fins extending therefrom. The LED modules are mounted on the first fins, respectively. Each heat pipe has two parallel sections respectively attached to a corresponding first fin and an inner circumferential periphery of the annular base.
