Embodiment

Below in conjunction with accompanying drawing of the present utility model, the technical scheme in the utility model embodiment is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole embodiments. Based on the embodiment in the utility model, what those of ordinary skill in the art were obtained under the premise of creative work is not made Every other embodiment, belongs to the scope of the utility model protection.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of LED headlamp of the present embodiment.The LED headlamp includes being provided with The lamp bead plate 2 of LED lamp bead 1, radiator 5.Radiator 5 is integrated die casting, and prefocus plate 6 is fixed with thereon.Processed on prefocus plate 6 Having be machined with the second slot to make way 621, the 3rd projection on the first projection 61, the second projection 62 and the 3rd projection 63, the second projection 62 63 are machined with the 3rd slot to make way 631.Stretching side 64 is machined with prefocus plate 6, stretches out on side 64 and is machined with 14 screws 641, First group of screw 642 of these screws 641 formation, second group of screw 643 and the 3rd group of screw 644, wherein first group of screw 642 by Two screws 641 are constituted, and second group of screw 643 is made up of four screws 641, and the 3rd group of screw 644 is by eight 641 groups of screws Into.On radiator 5 water proof ring 7 is set with prefocus plate 6.Two mutual corresponding mounting grooves 53 are machined with radiator 5, Two lamp bead plates 2 are individually fixed at two mounting grooves 53, and the bottom surface of lamp bead plate 2 is fitted with radiator 5, the LED on lamp bead plate 2 Lamp bead 1 is connected by line group 8 with external power source.The end of radiator 5, which is machined with some radiating ribs 52, radiator 5, to be dissipated Place is machined with heat dissipation wind channel 51 between hot muscle 52 and prefocus plate 6.
