Abstract
A light emitting diode (LED) lighting fixture includes a lamp housing including a heat conductive cover, and a light transmissive shield connected detachably to a periphery of the heat conductive cover to define a compartment therebetween. A base seat is disposed in the compartment. An LED lamp device is mounted on the base seat. A heat conductive unit is disposed in the compartment and includes at least one heat conductive pipe and a heat conductive medium flowing within the heat conductive pipe due to a change between a liquid state and a gaseous state thereof. The heat conductive pipe includes a heat exchange portion that absorbs heat generated by the LED lamp device, and a heat-dissipating portion that conducts heat absorbed by the heat exchange portion to the heat conductive cover.
