A light emitting diode (LED) lamp includes a standardized connector; an LED module; a heat dissipating module; an angle adjusting ring; and an isolating ring. The LED module is electrically connected to the standardized connector and includes a circuit board and at least one LED unit electrically connected to the circuit board. The heat dissipating module is for preventing the LED module from overheating and includes at least one heat pipe on which the LED unit is disposed, a rear heat dissipating shield, a piston module, a transmission module, a heat dissipating fan, and a convection fan. The angle adjusting ring is disposed between the LED module and the standardized connector for rotating the LED module so as to change a light emitting direction of the LED module. The isolating ring is used to avoid the electrical connection of the angle adjusting ring and the standardized connector.
