It states on H fonts on the side at the Lamp cup edge.
Preferably, the quantity of second pole piece is 8 pieces, is respectively arranged in two injection molding areas.
The utility model is provided through two sides opposite on the Lamp cup, enables and forms two independent zones in the Lamp cup
First pole piece in domain, which can be used as common cathode or common-anode uses, and the second pole piece in two isolated areas is then made
It is used for opposite pole piece, in injection moulding process, injection raw material only passes through the bottom of the first pole piece, you can complete in entire Lamp cup
Injection molding so that LED support injection molding is more uniform, solves existing LED support with partition-type pole piece and there is injection molding unevenness
Even technical problem.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to this practicality
Attached drawing is briefly described needed in the description of new embodiment or the prior art.It should be evident that being described below
In attached drawing be only that a part of the embodiment of the utility model is not paying wound for those of ordinary skill in the art
Under the premise of the property made is laborious, other drawings may also be obtained based on these drawings.
Fig. 1 is existing LED support structural schematic diagram；
Fig. 2 is that the utility model embodiment is bound foot LED support front view；
Fig. 3 is that the utility model embodiment is bound foot LED support rearview figure；
Fig. 4 is that the utility model embodiment is bound foot LED support side view；
Fig. 5 is that the utility model embodiment is bound foot LED support upward view.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
There is the common cathode or common-anode pole piece for forming strip, common cathode in the LED support of existing more lamp beads, patch support
Lamp cup bottom after injection molding is separated into several independent regions by pole or common-anode pole piece, during LED support is molded,
The plastic raw materials of injection hole injection need to sequentially pass through the bottom of polylith pole piece, could complete the injection molding of entire Lamp cup, far from note
The region for moulding mouth is molded non-uniform technical problem, reduces the qualification rate of LED support.
In order to solve the above-mentioned technical problem, Fig. 2-5 is referred to, the present embodiment provides a kind of uniform LED support of injection molding, packets
Include the Lamp cup 10 for installing LED chip and the pole piece being formed in Lamp cup 10.Fig. 3,5 are referred to, which can be pole
Piece cutting product or pole piece are bound foot product.Its difference lies in, the pole piece of pole piece cutting product is concordant with the lateral wall of LED support,
The bottom surface of pole piece is in plane；The bind foot pole piece of product of pole piece is then formed with flanging, pole piece extend out to LED support it is outer after be wrapped in
The bottom of LED support.The present embodiment elaborates by taking LED support of binding foot as an example.
Wherein pole piece includes the first pole piece 20 and the second pole piece 30 for being layed in 10 bottom surface of Lamp cup.First pole piece 20 runs through lamp
Opposite two sides on cup 10, enable and form two independent regions 11 in Lamp cup 10；Second pole piece 30 is set in two regions 11,
And second forms the injection molding area being connected between pole piece 30 and the first pole piece 20.First pole piece 20 can be used as common cathode or common-anode
It uses, the second pole piece 30 in two isolated areas 11 is then used as opposite pole piece.
The injection point 12 of LED support can be set on the side wall of Lamp cup 10, can be also set in two injection molding areas.In injection moulding process
In, after injection raw material fills up one of region 11, only pass through the bottom of the first pole piece 20, you can to another region 11 into
Row filling, and then realize the injection molding in entire Lamp cup 10.LED support provided in this embodiment is in injection moulding process, injection raw material
The injection molding of entire Lamp cup 10 only can be completed by one piece of pole piece so that LED support injection molding is more uniform, and solving existing has
The LED support of partition-type pole piece, which exists, is molded non-uniform technical problem.
In order to improve the practicability of LED support, the second pole piece 30 is formed on the other two sides on Lamp cup 10, second
Third pole piece 40 is formed between pole piece 30 and the first pole piece 20, third pole piece 40 is parallel to the first pole piece 20, and in interposition
Set disconnection.Specifically, it is in H fonts to form injection molding area between the first pole piece 20 and third pole piece 40；Second pole piece 30 is set to H fonts
On the side at upper close 10 edge of Lamp cup.The quantity of second pole piece 30 is 8 pieces, is respectively arranged in two injection molding areas.
LED support using the above structure separates shape since third pole piece 40 disconnects in centre position in the first pole piece 20
At isolated area 11 in, third pole piece 40 does not influence the independence in the region 11, within third pole piece 40 do not influencing to be molded
On the basis of effect, the first pole piece 20 and third pole piece 40 can also interact the positive/negative plate as LED chip, increase LED branch
The diversity of frame illumination effect.
Embodiments described above does not constitute the restriction to the technical solution protection domain.It is any in above-mentioned implementation
Modifications, equivalent substitutions and improvements etc., should be included in the protection model of the technical solution made by within the spirit and principle of mode
Within enclosing.
