Detailed description of the invention
Embodiment 1, heat radiating cup as depicted in figs. 1 and 2, including aluminum cup 11 be coated on the covered plastics layer 12 outside aluminum cup 11, heat radiating cup is vertically in three stage structure, the lamp holder connecting portion 101 that the cone mouth portion 103 that i.e. the cone cylinder portion 102 at middle part connects with cone cylinder portion big opening end connects with cone cylinder portion osculum end, aluminum cup 11 is predominantly located at inside cone cylinder portion 102, but a part is also respectively extended to cone mouth portion 103 and lamp holder connecting portion 101 in two ends.Covered plastics layer 12 is provided with the resisted shrinkage structure of shrinkage factor during for reducing covered plastics layer molding.Owing to covered plastics layer 12 is relatively thick with the end that connects in cone cylinder portion 102 in cone mouth portion 103, it is easier to shrink, the most preferably resisted shrinkage structure is arranged near this position.In the present embodiment, resisted shrinkage structure is specially groove 121, groove 121 along cone mouth portion 103 and cone cylinder portion 102 the end that connects be arranged circumferentially at least one, this groove 121 or an overall groove along whole hoop, or for the multiple grooves being distributed on heat radiating cup hoop, the shape of groove can be rectangle but be not limited to rectangle.Above-mentioned groove 121 the consumption that can reduce material is set, reduce cost, and covered plastics layer 12 be also minimized with the thickness held that connects in cone cylinder portion 102 in cone mouth portion 103, well solves the contraction problem of covered plastics layer, maintains appearance looks elegant.
Wherein, the mouth inner wall in cone mouth portion 103 is provided with the hoop location plane 14 for placing aluminium base.The radial width of described hoop location plane 14 is 1 10mm.When mounted, the bottom edge of aluminium base is positioned in the plane 14 of hoop location, plays the positioning action to aluminium base, too increases heat radiation contact area, thus strengthen aluminium base heat dispersion, can do higher effect while reducing cost.Further, between aluminium base bottom surface and hoop location plane 14, between aluminium base cylindrical anchor ring and the interior anchor ring of aluminum cup, it is provided with heat-conducting glue, carrys out improving radiating effect by heat-conducting glue.
It addition, the inner side of described lamp holder connecting portion 101 is provided with circumferentially distributed two wiring board draw-in groove 13, wiring board draw-in groove 13 axially extends, and directly wiring board can be snapped in draw-in groove, eliminate screw and fix, save material and operation, reduced cost.Further, can arrange at the bottom width both sides inwall of circuit board groove 13 and each a convex tendon is set, both sides convex tendon coordinates clamping wiring board, can effectively prevent wiring board from situation about rocking occurring after inserting wiring board draw-in groove, both sides convex tendon coordinates in horn-like, facilitate insertion into wiring board, again can clamping wiring board.
For reducing cost further, devise the attachment structure exempting from gluing between lampshade and heat radiating cup.It is provided with the LED of above-mentioned heat radiating cup 1, the cone mouth portion 103 of heat radiating cup is connected by buckle structure with lampshade oral area.Concrete, as shown in Figure 3, in order to realize being reliably connected of lampshade 2 and heat radiating cup 1, prevent both from coming off, described lampshade oral area is provided with flange 21, and the end of flange 21 is provided with snap ring 211, circumferentially arranged with at least two grab 16 inside the cone mouth portion of described heat radiating cup, described snap ring 211 and grab 16 snap-fit engagement, the most described lampshade oral area is provided with the location anchor ring 22 positioning cone mouth end surface on rear side of flange.And, described flange 21, circumferentially arranged with at least two card convex 212, is provided with draw-in groove 15 inside the cone mouth portion of described heat radiating cup, described card convex 212 snaps in draw-in groove 15.The buckle structure that above-mentioned heat radiating cup 1 is connected with lampshade 2, snap ring 211 and grab 16 snap-fit engagement realize axial anticreep, after the flange 21 of lampshade 2 inserts the cone mouth portion 103 of heat radiating cup, card convex 212 enters draw-in groove 15, it is possible to prevent lampshade 2 to rotate, just can reach the design requirement of lamp, lamps & lanterns factory's this technique of gluing water can be saved again, correspondingly reduce the cost of big glue.
Embodiment 2, as shown in Figure 4, from the difference of embodiment 1, the present embodiment is that resisted shrinkage structure is different, concrete, and cone mouth portion 103 is provided with plastic hoop 122 with the end that connects in cone cylinder portion 102 between aluminum cup and covered plastics layer.When Shooting Technique, first put aluminum cup 11, plastic cup 122 is put again outside aluminum cup 11, finally it is molded again, aluminum cup 11, plastic hoop 122, covered plastics layer 12 is made to form an entirety, so covered plastics layer 12 significantly reduces at the thickness in cone mouth portion 103 with the end that connects in cone cylinder portion 102, it is ensured that shrinks uniformly during formed product, keeps appearance looks elegant.
Embodiment 3, as it is shown in figure 5, on the basis of embodiment 2, as improved radiating efficiency further, can be further added by a heat conducting cover plate 17.Heat conducting cover plate 17 is by aluminium sheet punch forming, heat conducting cover plate 17 includes the cover board body of circular plate, the edge of described cover board body is provided with the flange turned over to heat radiating cup lamp holder connecting portion direction, flange is provided with circular arc concave inward structure to strengthen structural strength with the transition part of cover board body, flange periphery therein coordinates with heat radiating cup inner circle annular face contacts, realize the location of heat conducting cover plate, so, heat radiating cup can contact with heat conducting cover plate, and aluminium base is placed in heat conducting cover plate, significantly increase effective area of dissipation.
