In a preferable embodiment, the hea

In a preferable embodiment, the heat conducting member 200 includes a heat conductive platform 220 and a heat conductive pipe 240. The substrate 100 is fixed to an end surface or a side surface of an end of the heat conductive platform 220, while the other end or an inner hole of the heat conductive platform 220 is connected to the heat conductive pipe 240. Specifically, the heat conductive platform 220 and the heat conductive pipe 240 may be integrally formed, or be connected to each other by welding the ends thereof, or, an end of the heat conductive pipe 240 may also be received in a hole (the inner hole mentioned above) defined at an end of the heat conductive platform 220 opposite to the heat conductive pipe 240, and the end of the heat conductive pipe 240 is fixed to the heat conductive platform 220. Such arrangement can provide a variety of distributions of the LED lamp on the premise of meeting the focal distance standard of automobile headlamps, for example, if the substrate 100 is positioned on the end surface of the heat conducting member 200, the single LED lamp or the multiple LED lamps can be flatly and evenly distributed. Referring to FIG. 7, FIG. 11, FIG. 12, and FIG. 13, when the substrate 100 is positioned on the side surface of the heat conducting member 200, a side surface provided with the heat conducting member 200 or the multiple LED lamps can be distributed circlewise, symmetrically or asymmetrically (referring to FIG. 8), or dislocation distributed (referring to FIG. 8), so as to implement a high-low lamp, a high beam or a dipped headlamp of the LED automobile headlamp.Referring to FIG. 2 and FIG. 3, the heat conductive platform 220 may be in a “T” shape, while the substrate 100 is fixed to a top of the “T”; referring to FIG. 5, FIG. 6 and FIG. 7, the heat conductive platform 220 may also be a flat cuboid, while the substrate 100 is fixed to opposite sides of the cuboid, so that the LED lamps are symmetrically or asymmetrically distributed relative to the cuboid (referring to FIG. 8); referring to FIG. 9, FIG. 10 and FIG. 11, the heat conductive platform 220 may also be a polyhedron having a strip shape, the substrate 100 can be positioned on one surface of the polyhedron or several substrates 100 are positioned on every one surface of the polyhedron, so that the LED lamps are circlewise distributed relative to the polyhedron.
