An LED automobile headlamp includes an LED lamp positioned on a substrate (100); a heat conducting member (200) having a strip shape, with the substrate (100) being fixed to an end of the heat conducting member (200), and the heat conducting member (200) being internally filled with a low-boiling liquid; and a heat dissipating member (300), including a heat dissipating cylinder (320) and a plurality of heat dissipating fins (340), wherein the heat dissipating cylinder (320) defines a through hole to receive the heat conducting member (200), and the plurality of heat dissipating fins (340) are fixed to a periphery of an end of the heat dissipating cylinder (320) away from the substrate. The LED automobile headlamp uses an LED lamp instead of the traditional tungsten filament and HID, and transmits the heat generated by the LED lamp to the rear end by means of the circulation of the low-boiling liquid in the heat conducting member (200), and then uses the heat dissipating member (300) to dissipate heat.
