Claim Text:
1. An LED automobile headlamp, comprising: an LED lamp positioned on a substrate, the LED lamp having connected wires; a heat conducting member having a strip shape, the substrate being fixed to the heat conducting member, and the heat conducting member being internally filled with a low-boiling liquid; and a heat dissipating member comprising a heat dissipating cylinder and a plurality of heat dissipating fins, wherein the heat dissipating cylinder defines a through hole to receive the heat conducting member, and the plurality of heat dissipating fins are fixed to a periphery of an end of the heat dissipating cylinder away from the substrate, the heat dissipation member having bypass pathways outside of the through hole and extending with the through hole, the wires being laid in the bypass pathways; wherein the heat conducting member occupies substantially the entire center of the through hole in the heat dissipating member; wherein the bypass pathways of the heat dissipation member provide both a pathway for the wires and an air insulator to limit heat transfer through the sides of the heat conducting member.
