The specific embodiment

In order to more fully understand technology contents of the present utility model, the technical solution of the utility model is further introduced and explanation below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, three-dimensional structure diagram for the utility model specific embodiment, a kind of novel highly dense radiator structure high-powered LED lamp of the utility model comprises great power LED illuminator 1, is used for fixing the aluminium base circuit board 2 of great power LED illuminator and the metal lamp housing 3 that connects with aluminium base circuit board, the front end of metal lamp housing 3 is provided with LED lenticular body 7, LED lenticular body 7 is that interference fit (clamp-oning with forcing press) connects with the front end of metal lamp housing 3, also can adopt the mode of screw or viscose glue gluing.The LED illuminator is 5, and the LED lenticular body is provided with and corresponding 5 the lens section (not shown)s of LED illuminator.

The utility model not only can be used for the occasion of dc source, the lighting demand that more can be used for AC power, for being suitable for the environment for use of domestic power grid alternating current 220V, be provided with one in the lower end of metal lamp housing 3 and be used for electrically connecting the lamp holder 4 of AC power, and be located in the lamp holder 4 and the led drive circuit 5 that connects with the LED illuminator 1 of aluminium base circuit board 3.Metal lamp housing 3 skins can be provided with anodic oxide coating, and (traditional high-powered LED lamp adopts die casting aluminium, carry out anodic oxidation on its surface a lot of difficulty is arranged, even if can carry out anodic oxidation, effect is not good yet, the cost height), this anodic oxide coating can be realized various color, the more important thing is its surperficial insulating barrier, when this is applied to the illuminating product of AC power for the utility model, very important techniques advantage is arranged.

For realizing connecting between metal lamp housing 3 and the lamp holder 4, be provided with metal lamp housing connection part 6 in the lower end of metal lamp housing 3, be provided with lamp holder connection part 41 in the upper end of lamp holder 4, metal lamp housing connection part 6 connects with lamp holder connection part 41 by screw.Metal lamp housing 3 and connecting of metal lamp housing connection part 6 are thread connection (also can with the interference fit connecting mode of extruding type or the buckle-type connecting mode that relies on the strain of plastic parts to constitute).The end of lamp holder 4 is provided with and is used for the threaded port (also can adopt the connecting mode of card slot type) that connects with the AC power end, lamp holder 4 can be integrally formed structural member with lamp holder connection part 41, also adopts by ultrasonic wave to fuse or the split-type structural of other connecting mode.

Metal lamp housing 3 is one to be circumferentially with a plurality of fin 30 (as shown in Figure 8, the quantity of fin is many more, area is big more, radiating effect is good more, the quantity of fin and big I are set according to the power of LED illuminator and quantity) tubular body, (best mode is for being squeezed into aluminium base circuit board the interference fit connecting mode in the metal lamp housing for close-coupled with metal lamp housing 3 for aluminium base circuit board 2, the external diameter of aluminium base circuit board is greater than the aperture of metal lamp housing, clamp-on by forcing press, reach interference fit, can realize the good heat radiating between aluminium base circuit board and the metal lamp housing).What the metal lamp housing adopted is that (fin not only adopts the form of arc angle to cross sectional shape aluminium section bar as shown in Figure 8, also can adopt the version of flat sided straight shape), metal lamp housing outside can be processed into different shape as required, as shown in the drawing the taper shape of embodiment one, two, three, four, sphere, conical band chimb etc.

As Fig. 2, shown in Figure 3, structure for the utility model embodiment one, the lower end that be aluminium base circuit board 3A different with aforementioned specific embodiment is processed with groove (not doing sign), and the upper end of lamp holder connection part 41A is provided with protuberance, thereby reaches the purpose that is fixedly connected by the crimp screens.

As Fig. 4, shown in Figure 5, structure for the utility model embodiment two, be that with aforementioned instantiation difference the outward appearance of metal lamp housing 3B is a spherical shapes, the semi-round ball convex lens of the lenticular body 7B that the front end of metal lamp housing 3B is provided with for protruding, the quantity of LED illuminator 1B is one.

As shown in Figure 6, for the utility model embodiment three structure, be that with aforementioned embodiments two differences the profile of its metal lamp housing 3C is shouldered taper shape.

As shown in Figure 7, be the structure of the utility model embodiment four, its difference is that the profile of its metal lamp housing 3D is the bullet of straight flange, and the quantity of LED illuminator 1D is one, and lenticular body 7D is a semi-spherical shape.

As shown in Figure 8, section bar sectional view for the metal lamp housing 3 of the utility model, metal lamp housing 3 adopts the aluminium pipe material of stretch forming, and whether its center is hollow can the setting on demand, and the thickness of its fin 30, width, quantity can be made different designs according to need.

Fig. 9 is another specific embodiment cross-sectional view of aluminium base circuit board of the utility model, because the thickness of aluminium base circuit board 2 limited (too thick increase cost), and aluminium base circuit board 2 and the too small radiating effect that can influence of the contact area of metal lamp housing 3, thereby can consider to set up protuberance in the periphery of aluminium base circuit board, to increase the contact area of aluminium base circuit board and metal lamp housing, improve the radiating effect between aluminium base circuit board and the metal lamp housing.

In sum, the utility model can adopt the aluminium section bar of extruding or stretch forming because adopted the metal shell of tubular body, not only saves material, can also realize the anodic oxidation of metal shell, makes top layer of the present utility model have insulating effect.Aluminium base circuit board adopts the interference fit of extruding type to connect with the metal lamp housing, can realize good heat conduction, radiating effect, reduce the temperature of aluminium base circuit board greatly, thereby reduce the temperature of great power LED illuminator, thereby make the life-span of LED illuminator be higher than high-powered LED lamp of the prior art.

The above angle from specific embodiment discloses further to technology contents of the present utility model; but do not represent embodiment of the present utility model and rights protection to be confined to this, rights protection scope of the present utility model should be as the criterion in claims of the present utility model.
