The specific embodiment
As shown in Figure 1 and Figure 2, a kind of high-power LED lamp of the present invention comprises housing 1 and led light source 2, and housing 1 has a central part 11 and an outer ring 13, is connected with a plurality of fin 12 between central part 11 and outer ring 13.Forming between the adjacent fin 12 can be for the heat dissipation channel of circulation before and after the air.Also fixedly mount a driving power box 3 and lamp bracket 4 at the rear portion of housing 1, housing 1, driving power box 3 are made by casting aluminium material, have good heat conduction and heat radiation performance.
As shown in Figure 3, the front end of housing central part is provided with a circular groove 14, led light source 2 just is installed in this groove 14, lens 6 cover on the opening of groove 14 and with led light source 2 and are enclosed in the groove 14, be provided with sealing ring 61 between the edge of lens 6 and groove 14, can prevent that moisture from entering infringement led light source 2 in the groove 14.Lens gland 5 is pressed in the edge of lens 6, also rubber washer can be set between lens gland 5 and the lens 6.Lens gland 5 is fixed on the housing 1 by screw 51, and for the purpose of attractive in appearance, the central part that screw 51 passes housing 1 from behind is threaded with lens gland 5.
In fitting structure of the present invention, because the setting of fin, lamp casing has very big cooling surface area and unobstructed air flow passage, and the heat that is produced by led light source 2 can fully be distributed by housing 1; The heat that driving power 8 produces then can distribute by the driving power box, in order to increase the area of dissipation of driving power box, also is provided with outwards outstanding radiating wing 39 (as shown in Figure 4) in the side of box body 32.
In the present invention, the shape of fin can be diversified on the housing 1, except that Fig. 1, line of radiation shape shown in Figure 2, fin 12 also can be helical radial (as shown in Figure 5), wave radial (as shown in Figure 6), helical cross network (as shown in Figure 7), ellipse cross network (as shown in Figure 8), straight line cross network (as shown in Figure 9) or star-like radial (as shown in figure 10).With comparing of line of radiation shape, the fin of other shape has bigger area of dissipation, so radiating effect can be better.
