An LED lamp includes a heat absorbing member having a hollow, cylindrical configuration, a lamp base, a plurality of LED modules and a heat sink. The heat absorbing member defines a through hole therein. The heat sink is secured to a top portion of the heat absorbing member. The lamp base is secured to a bottom portion of the heat absorbing member. The LED modules are mounted on an outer sidewall of the heat absorbing member, and each of the LED modules includes a printed circuit board and a plurality of LEDs mounted on the printed circuit board. Each of the heat pipes has an evaporating portion received in an inner sidewall of the heat absorbing member and a condensing portion connecting with the heat sink. The condensing portions of the heat pipes are radially arranged on the heat sink, radiating outwardly from a central point of the heat sink.
