An LED lamp includes a bulb, an LED module having a plurality of LEDs received in the bulb and a heat dissipation apparatus supporting and cooling the LED module. The heat dissipation device includes a heat sink, a hollow first heat conductor, and a heat pipe. The heat sink has a hollow base and a plurality of fins mounted on the base. The hollow first heat conductor is supported by the heat sink. The heat pipe is retained in the heat sink and the first heat conductor in such a manner that an outer periphery surface of the heat pipe is tightly enclosed by the base and the first heat conductor. The LEDs are distributed on the first heat conductor.
