Specific embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment.
Preferred embodiment one：
This preferred embodiment discloses a kind of lamp bar.As shown in Figures 2 and 3, this lamp bar includes LED 1 and substrate 2, in base
Multipair U-shaped draw-in groove 21 is offered on plate 2, U-shaped draw-in groove 21 forms opening on a side of substrate 2；LED 1 is welded with
A pair of fixture block 11, a pair of the fixture block 11 in a LED 1 is adapted with a pair of U-shaped draw-in groove 21, and fixture block 11 can be located in substrate 2
Slip into along U-shaped draw-in groove 21, skid off (as shown by the arrows in Figure 2) in plane, U-shaped draw-in groove 21 can limit LED 1 perpendicular to substrate
It is moved on 2 direction.
LED 1 can be slipped into, skidded off U-shaped draw-in groove 21 and be fixed on substrate 2 by U-shaped draw-in groove 21 by fixture block 11 thereon
On, LED 1 easy accessibility, disassembly efficiency are high, push-pull effort is sufficiently high, and after LED 1 is installed, position accurately and contacts good, works as lamp
It is convenient to change when some LED 1 in bar does not work or brightness is deteriorated, and is not result in that whole lamp bar is cancelled, use cost is low；
It is completely embedded between LED 1 and substrate 2, will not will not judge LED 1 by accident and damage because outside vibration is with regard to loose contact, will not
Lead to use cost to raise because changing misjudged LED 1；Only need to be in new LED when needing to change other type product
On lamp 1, setting position welds a pair of fixture block 11 and can use, and the structure of substrate 2 need not make any change.
The concrete shape of fixture block 11 does not limit, can smooth slip into, skid off U-shaped draw-in groove 21 and can fix with U-shaped draw-in groove 21 in case
Only LED 1 is moved on the direction perpendicular to substrate 2.Along cutting perpendicular to LED 1 top surface direction on fixture block 11
Face is in inverted T-shaped or L-shaped, can also be in other shapes.When the cross section of fixture block 11 is L-shaped, in any one LED 1 one
The L-shaped structure of fixture block 11 can relatively inwardly be fastened, can mutually privately turned-out, can also be one inside one outwards
(that is, the footing of two fixture blocks 11 is both facing to right side or towards left side), can effectively fix LED 1.
The concrete shape of U-shaped draw-in groove 21 does not limit, can with fixture block 11 cooperation avoid only LED 1 in the direction perpendicular to substrate 2
On be moved.When being in inverted T-shaped along the section perpendicular to LED 1 top surface direction on fixture block 11, edge on U-shaped draw-in groove 21
Perpendicular to LED 1 top surface direction section it is also preferred that be in inverted T-shaped；When edge cutting perpendicular to LED 1 top surface direction on fixture block 11
When face is L-shaped, along the section perpendicular to LED 1 top surface direction it is also preferred that L-shaped on U-shaped draw-in groove 21, and the L-shaped of U-shaped draw-in groove 21
The direction of structure and fixture block 11 are towards identical.
On the basis of said structure, as shown in Figure 4 and Figure 5, the side in substrate 2 is provided with baffle plate 4, and baffle plate 4 possesses
Depressed position and reset position.Specifically, as shown in figure 4, U-shaped draw-in groove 21 is in substrate 2 side when baffle plate 4 is in depressed position
On opening be in opening-wide state, be the dismounting slot milling of LED 1；As shown in figure 5, when baffle plate 4 is in reset position U
Opening on substrate 2 side for the shape draw-in groove 21 is in the state of being blocked it is ensured that the LED 1 being installed in place will not be slided at opening
Go out.
In order to be able to reach the position preferably limiting LED 1, baffle plate 4 is arranged at the position close proximity to substrate 2,
When the side that baffle plate 4 is in reset position season baffle plate 4 is fitted on the side of substrate 2.Now, LED 1 will not be in U-shaped card
Shake in groove 21 (that is, LED 1 will not be moved along the axis direction of U-shaped draw-in groove 21).
Baffle plate 4 and substrate 2 can be separate two structures, and baffle plate 4 can open wide on substrate 2 side as needed
Opening or block the opening on substrate 2 side.Baffle plate 4 and substrate 2 can also be integral structures, the both sides of baffle plate 4
Termination connects on a substrate 2；Baffle plate 4 in this structure possesses certain retractility and flexibility, the energy in the middle part of it in pressed by external force
Move down, to open wide the opening on substrate 2 side.
On the basis of said structure, the lower section of baffle plate 4 is provided with least one elastic device 3；At elastic device 3
When compressive state, baffle plate 4 is in depressed position, and when elastic device 3 is in reset state, baffle plate 4 is in reset position.
The installation base surface of elastic device 3 is not specifically limited, and can be the planar structure extended by substrate 2 side, can
To be to install, use any operative face of this lamp bar or other plane, can stably support elastic device 3, ensure elasticity
Device 3 provides for baffle plate 4 and does enough elastic force.
In terms of the side of lamp bar, that elastic device 3 can be exposed to baffle plate 4 lower section it is also possible to lateral surface in baffle plate 4
Form block surface vertically downward, block elastic device 3 using block surface, do not affect the normal work of elastic device 3.
The concrete device of elastic device 3 does not limit, and can upspring to shift baffle plate 4 onto substrate 2 side after LED 1 is installed
Position at.Elastic device 3 is preferably spring or spring leaf, can also be other devices.
In order to make baffle plate 4 and substrate 2 can reach best laminating effect, each elastic device 3 is arranged on two pairs of U-shaped draw-in grooves
At position between 21.It is understood that corresponding to an elasticity respectively for the both sides of each U-shaped draw-in groove 21 for whole lamp bar
Device 3.
During mounted LED lamp 1, baffle plate 4 pressed down on, snap in U-shaped draw-in groove 21 slot milling for fixture block 11, now elasticity dress
Put 3 and be in compressive state；The fixture block 11 of LED 1 is slipped in U-shaped draw-in groove 21, completes the installation of LED 1；Remove on baffle plate 4
Pressing force, elastic device 3 resets, and baffle plate 4 is pushed at the lateral location of substrate 2 by elastic device 3.
In order to ensure that LED 1 electrically connected so that LED normal work with substrate 2 circuit, fixture block 11 is by conductive metal material system
Become and be welded on the pin of LED 1.
Preferred embodiment two：
This preferred embodiment discloses a kind of backlight module, including the lamp bar as described in preferred embodiment one.In this lamp bar
LED easy accessibility, can only change the lamp of this damage and need not scrap whole lamp bar when some LED has not worked,
Reduce use cost, improve the replacing efficiency of lamp bar；LED installation effectiveness in lamp bar is high, and then improves backlight mould
The packaging efficiency of group.
Note, above are only presently preferred embodiments of the present invention and the know-why used.Those skilled in the art can manage
Solution, the invention is not restricted to specific embodiment described here, can carry out various obvious changes for a person skilled in the art
Change, readjust and substitute without departing from protection scope of the present invention.Therefore although being entered to the present invention by above example
