Abstract
The utility model discloses a kind of side entering type lamp bar with pad, including pcb board and it is arranged at the positive multiple LEDs spaced apart of the pcb board, also include multiple pads, the bottom surface of pad is welded in the pcb board front, and the top surface of the pad is positive highly high 0.2mm relative to the pcb board relative to top surface of the positive height of the pcb board than the LED.The light guide plate of the utility model LCD backlight module can be pressed on the pad in side entering type lamp bar so that light guide plate will not contact with the LED in side entering type lamp bar, damage LED in side entering type lamp bar by pressure so as to avoid light guide plate, ensure that LCD TV is normally shown.
Description
Technical field
Side entering type lamp bar is the utility model is related to, more particularly to a kind of side entering type lamp bar with pad.
Background technology
It is increasing now with the size of LCD TV, then in the backlight module for resulting in TV LCDs
LGP（Light guide plate）Weight it is also increasing, TV often occurs that light guide plate damages side entering type lamp bar by pressure in use（That is lamp bar
Installed in the upper and lower, left and right of light guide plate）On LED, do not worked phenomenon so as to LCD TV occur.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of side entering type lamp bar with pad, can avoid leaded light
Plate damages the LED in side entering type lamp bar by pressure, so as to ensure that LCD TV is normally shown.
The technical solution of the utility model is：A kind of side entering type lamp bar with pad is provided, including pcb board and is arranged at
The positive multiple LEDs spaced apart of pcb board, in addition to multiple pads, the bottom surface of pad are being welded in the pcb board just
Face, the top surface of the pad relative to top surface of the positive height of the pcb board than the LED relative to the pcb board just
The high 0.2mm of height in face.
The multiple pad is arranged between the positive one end of the pcb board and both ends.
The pad is made of copper.
The pad is made of glass cloth substrate, and is covered with the bottom surface using pad made of glass cloth substrate
Second copper foil layer.
The pcb board includes aluminium base and the insulating heat-conductive glue-line and the first bronze medal that are arranged at from bottom to top on the aluminium base
Layers of foil, the pin of LED are welded on the first copper foil layer of pcb board.
The multiple pad is arranged between the positive both ends of the pcb board and both ends.
The utility model proposes the side entering type lamp bar with pad, the top surface of pad is relative to the positive height of pcb board
More positive highly high 0.2mm relative to pcb board than the top surface of LED, the light guide plate of such LCD backlight module can be pressed in side
Enter on the pad in formula lamp bar so that light guide plate will not contact with the LED in side entering type lamp bar, so as to avoid light guide plate pressure
LED in bad side entering type lamp bar, ensure that LCD TV is normally shown.
Brief description of the drawings
Fig. 1 is the structure chart of lamp bar in the utility model embodiment.
Fig. 2 is the enlarged drawing at A in Fig. 1.
Fig. 3 is that light guide plate is pressed in the schematic diagram in lamp bar in the utility model embodiment.
Fig. 4 is the structural representation of pcb board in the utility model embodiment.
Embodiment
Such as Fig. 1, the side entering type lamp bar with pad that is proposed in the utility model embodiment should side entering type with pad
Lamp bar is applied in the backlight module of LCDs.There is the side entering type lamp bar of pad to include pcb board 10 and be arranged at PCB for this
The positive multiple LEDs 20 spaced apart of plate 10, it should also include multiple pads 30 with the side entering type lamp bar of pad, pad 30
Bottom surface is welded in the front of pcb board 10.Such as Fig. 2, the top surface of pad 30 is relative to the positive height H1 of pcb board 10 than LED 20
Top surface is relative to the positive high 0.2mm of height H2 of pcb board 10（It is the thickness of the thickness ratio LED 20 of pad 30 in actual production
Big 0.2mm）.Such as Fig. 3, the light guide plate 40 of such LCD backlight module can be pressed on the pad 30 in side entering type lamp bar so that
Light guide plate 40 will not be contacted with the LED 20 in side entering type lamp bar, and LED in side entering type lamp bar is damaged by pressure so as to avoid light guide plate
Lamp, ensure that LCD TV is normally shown.
Multiple pads 30 are arranged between 10 positive one end of pcb board and both ends, are arranged between the positive both ends of pcb board
Pad can be between two adjacent LEDs lamp.There is spacing, the spacing is according to the length of light guide plate between two neighboring pad
Spend to set so that the both sides of the length of light guide plate have pad.There are two pads, the two pad pads exist in the present embodiment
The both sides of the length of light guide plate, it is possible to have three pads, these three pads are preferably to pad in the both sides of the length of light guide plate
And centre.
Such as Fig. 4, pcb board 10 includes aluminium base 11 and the He of insulating heat-conductive glue-line 12 being arranged at from bottom to top on aluminium base 11
First copper foil layer 13, i.e. pcb board use aluminium base, and the first copper foil layer is conductive layer, and the pin of LED is welded on the of pcb board
On one copper foil layer.
Pad 30 can be made of copper, and the pad being made of copper is welded on the first copper foil layer on pcb board.System
Copper is pressed into certain thickness sheet material when making pad, produced by punching press, cleaning, nickel plating, mist tin, flow package, nickel plating
Push-pull effort after can increasing pad on pcb board with mist tin, and the inoxidizability of lifting pad.
Pad 30 can also be made of glass cloth substrate, and this is provided with using the bottom surface of pad made of glass cloth substrate
Second copper foil layer, this is welded on the first copper foil layer on pcb board using pad made of glass cloth substrate.Will during making pad
Glass cloth substrate makes pad by punching press, cleaning, packing flow.Copper is used using pad made of glass cloth substrate is relative
Into pad for the pressure that can bear it is relatively small, therefore more than 55 cun of large size TV prioritizing selection is made of copper
Pad.In addition, the push-pull effort after being arranged on using pad made of glass cloth substrate on pcb board need to be more than or equal to 5KG, using copper
Push-pull effort after manufactured pad is arranged on pcb board needs to be more than 10KG.
In another embodiment, multiple pads are arranged between the positive both ends of pcb board and both ends.
In actual production, the size of pad（Length, unit mm）Can be：2x2x0.8、2x2x1、2x2x1.2、
2x3x0.8,2x3x1,2x2x1.2,4x4x0.8,4x4x1 and 4x4x1.2.
Only to illustrate design of the present utility model, one of ordinary skill in the art's specific embodiment above exists
Various deformation and change can be made under design of the present utility model, these deformations and change are included in guarantor of the present utility model
Within the scope of shield.
