Specific implementation mode：
The utility model discloses a kind of LED light bar, the internal substrate conduct made of the punching of strip metal frame
LED illuminator is fixed on the metal substrate, can form good heat dissipation effect, substrate can select by the substrate of LED light bar
It, can also aluminium nickel plating or copper nickel plating material with iron nickel plating material.Wherein, structure such as Fig. 1 and Fig. 2 after substrate punching molding
It is shown.It laterally arranges on substrate multiple repetitive units 8, LED light bar length is realized by the arrangement quantity of repetitive unit 8
Adjustment.The substrate length of punching molding can design longer in advance, specifically can setting according to lamp bar when producing LED light bar
Meter length freely cuts the length of substrate, and this formal freedom is flexible so that the range of applicability of substrate is wider.
It is unfolded to be described in detail its concrete structure with a repetitive unit 8, repetitive unit 8 includes AC conductor wires successively from top to bottom
1, upper DC conducting line segments 3, heat sink 5, lower DC conducting line segments 4 and DC conductor wires 2, above-mentioned each component part are laterally arranged in strip,
And be mutually isolated in the middle part of each part mentioned above and be not connected to each other, only the both ends connecting bridge 9 of each part mentioned above will each other
End it is longitudinally connected together, avoid scattering.The connecting bridge 9 not only serves as the effect of dowel on the substrate being punched,
The realization of the electrical connection between the repetitive unit 8 of adjacent connection is also primarily served, between adjacent two repetitive units 8
Connection is also to rely on the connecting bridge 9 and realizes interconnection.Connecting bridge 9 at different location needs to be shone according to each inside LED light bar
Connection in series-parallel relationship between body, targetedly carries out secondary punch in the fabrication process.
Heat sink 5 is the dumbbell-shaped structure that both ends are wider, middle part is relatively narrow, and the wider region in both ends forms radiating area 12, in
The relatively narrow region in portion forms illuminator installing zone 6.It, can also be by upper DC conducting line segments 3 to coordinate the electrical connection of two electrode of illuminator
Protrusion 7 is set to the direction of heat sink 5 respectively with the middle part of lower DC conducting line segments 4, protrusion 7 is enabled to exactly correspond to heat sink 5
The illuminator installing zone 6 at middle part.LED illuminator 10 is pasted onto at illuminator installing zone 6（As shown in Figure 3）, LED illuminator 10
LED chip may be used, can also use LED lamp bead, the luminescent color of illuminator that can select white, or colored.
In the present embodiment attached drawing by taking LED chip as an example, after LED chip is pasted, two electrodes of LED chip are divided with tinsel 11
It is not connect with the protrusion 7 on upper DC conducting line segments 3 and lower DC conducting line segments 4.It is installed on heat sink 5 in each repetitive unit 8
LED illuminator 10 can be only one, or the form of multiple parallel connections is installed in parallel according to multiple, then it is corresponding on
The length of DC conducting line segments 3 and lower DC conducting line segments 4 wants the growth of appropriateness, guarantees the Capacity design requirement for meeting electric current.
After installing LED illuminator 10 on the substrate of above structure, for the insulation and connection between each electrode
Protection, is coated with plastic-sealed body in the outside of substrate, only enables the front of LED illuminator 10, the radiating area of 5 positive and negative of heat sink
12 and substrate both ends junction it is exposed outside, be used in combination fluorescent glue to cover 10 positive exposed section of LED illuminator
（As shown in Figure 4 and Figure 5, the interconnecting piece of end is omitted in figure）.
Since before plastic packaging, the connecting bridge 9 on substrate is in connected state, entire LED light bar also temporarily cannot achieve electricity
Connection relation needs targetedly to carry out secondary punch to internal connecting bridge 9 after plastic packaging, to realize circuit
Connection relation.No matter the connection relation between the repetitive unit 8 of each adjacent connection is series connection or in parallel, first, respectively repeats list
1 equal cross connection of AC conductor wires between member 8, and the AC conductor wires 1 in each repetitive unit 8 and respectively upper DC conducting line segments 3 it
Between connecting bridge 9 must then be punched disconnected, which is used to connect the end of incoming cables of alternating current.Secondly, each repetitive unit 8 it
Between heat sink 5 between cannot interconnect, the connecting bridge 9 that electrical connection can be established between each heat sink 5 is punched out disconnected.
Again, it is not interconnected between all upper DC conducting line segments 3 and lower DC conducting line segments 4, energy between DC conducting line segments 3 and lower DC conducting line segments 4 need to be gone up
The whole punchings of connecting bridge 9 for establishing electrical connection are disconnected.Connecting bridge 9 between lower DC conducting line segments 4 and DC conductor wires 2 is still protected
It stays, the upper DC conducting line segments 3 and lower DC conducting line segments 4, DC conductor wires 2 exposed to outside plastic-sealed body is separately connected driving power.Its
The connecting bridge 9 at his position needs to be punched out depending on specific circuit connecting relation.
The secondary punch of connecting bridge 9 can be carried out after plastic packaging, the structure after punching is as shown in fig. 6, cut-off
Cavity is formed at connecting bridge 9, can also be applied at the position for being exposed to plastic-sealed body and be covered with reflectorized material, realized to LED illuminator
Light reflection.Fig. 7 gives the inside connection diagram of the one of which embodiment formed between each repetitive unit 8, from the figure
It can clearly find out the place of incision of each connecting bridge 9.From finally formed substrate connection relationship, repetitive unit F and E is
Parallel relationship, repetitive unit D and C are parallel relationship, and repetitive unit B and A is parallel relationship, above-mentioned adjacent connection and in parallel two
A repetitive unit can be considered a cycling element, constitute and be connected in series between each cycling element.Fig. 7 is only used for illustrating
To realizing the meaning of circuit connecting relation, other specific embodiments are omitted bright connecting bridge 9.
The LED light bar that the utility model provides, the formation of circuit connecting relation are that second after plastic packaging was punched
It is realized in journey, facilitates the designer of different circuits that can realize the connection of different circuits by the substrate, further increase this
The versatility of the provided substrate of utility model.
Above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
Other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the right of the utility model.
