The utility model relates to a LED car headlamp, which includes a copper woven net and a heat pipe. Because of the heat tube outer surface is directly welded with a ceramic substrate backside copper clad, outer surface of the ceramic substrate is welded with LED chip, the other end of the outer surface of the ceramic substrate is directly welded with a connector; the ceramic substrate by soldering on the outer surface of heat pipe, welding layer of LED chip by flip chip bonding on the external surface of the ceramic substrate the. At work, the LED chip releases heat, passes through the welding layer to the ceramic substrate, and then passes directly through the welding layer to the heat pipe, and then rapidly transfers heat to the heat dissipation belt of the copper weaving net by the heat pipe, so as to achieve rapid heat dissipation. It is beneficial to prolong the service life of LED chip. Because the outer surface of the heat pipe and the copper woven mesh heat dissipation belt are interlaced with the outer surface of the copper wire, the gap space is formed. Filling the solder in the gap space has the function of heat dissipation and fixing at the same time, so as to achieve the effect of improving the heat dissipation effect and the convenient installation and operation.
