Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig.1-5, a kind of positioning light conducting plate structure of setting lamp bar protective device, including lamp bar 1, lamp bar protective cover
2 and backboard 4, lamp bar 1 be made of lamp bar pcb board 11, LED lamp bead 12 and iron block 13, LED lamp bead 12 is uniformly arranged in lamp bar
On pcb board 11, iron block 13 is installed between LED lamp bead 12, and iron block 13 is corresponding with the through-hole 3 that lamp bar protective cover 2 is equipped with, lamp
The fitting of bar protective cover 2 is installed in lamp bar 1 and is inserted by iron block 13 fixed in through-hole 3, and such lamp bar protective cover 2 is assemblied in lamp
When item 1 just more securely, it is not easy to loosen；In the present embodiment, since lamp bar protective cover 2 is that a kind of 0.9mmPMMA or PC is transparent
The component of material（PMMA is organic glass, and PC is makrolon）, and the wherein standby 1.05mm gums of one side, and the gum used
For high viscosity and heat safe 3M glue, glue thickness 0.1-0.5mm.Consequently facilitating the installation of lamp bar protective cover 2, and do not influence light
Learn effect；Trepanning is additionally provided on lamp bar protective cover 2, bore size arranges size with LED lamp bead 12 and matches；Lead on backboard 4
It crosses lock screw 5 and heat-dissipating aluminium plate 6 is installed, by pasting hot glue and being bonded on heat-dissipating aluminium plate 6 in lamp bar 1, light guide plate 8 is positioned over the back of the body
In plate 4, light guide plate 8 is corresponding with lamp bar 1, (can also be used in this scheme and screw tight peace by locking screw 7 on heat-dissipating aluminium plate 6
Scheme equipped with light guide plate 8 and lamp bar 1, while being also required to side chain)；And light guide plate 8 and LED lamp bead 12 are at a distance of 0.3-0.7mm；The back of the body
It is also bonded on plate 4 and silicagel pad 9 is installed, on orientation of the silicagel pad 9 with light guide plate 8, such light guide plate 8 is comprehensive to be had
Positioning, and realize the orientation distance with LED lamp bead 12, it is reliable and stable.
It is fixed on backboard by lock screw in this heat-dissipating aluminium plate or lamp bar passes through patch thermal paste and the fixed side of heat-dissipating aluminium plate
Case：Lamp bar protective cover single-sided back-adhesive, is fixed by way of fitting with lamp bar, and the thickness of lamp bar protective cover compares lamp bar（LED light
Pearl）The high 0.3-0.7mm of height, this height is exactly lamp bead and leaded light plate spacing；Since the thickness of lamp bar protective cover can
To be made very stable, tolerance can be made very small, so lamp bead can be also made very precisely with light guide plate spacing dimension.Light guide plate
Being located through for other directions is positioned in backplane silicagel pad；Light guide plate is comprehensive in this way positioning, and realizes
Lamp bead and guide-lighting plate spacing are reliable and stable.Such backboard old compared to before by lampshade positioning light guide plate design adds flange fixed
Position mode substantially reduces the design gap value of light guide plate and backboard, realizes a kind of scheme of narrow frame or Rimless design.
Increase a through-hole on lamp bar protection cover structure, SMT is brave in lamp bar connects a cylindrical iron block；Iron when assembly
Block is inserted into through-hole；When lamp bar protective cover is assemblied in lamp bar so just more securely, it is not easy to loosen.
For lamp bar protective cover due to there is 5-10 hole, forced area is larger, and stress very uniformly can protect lamp bead very well
It is not expanded and squeezes by light guide plate, and such be installed on can almost be installed in all side-light type lamp bars, it is adaptable.
The present invention is provided with the positioning light conducting plate structure of lamp bar protection closure assembly, installs a lamp bar protection additional in lamp bar 1
Cover 2 is protected LED lamp bead not squeezed by light guide plate and is destroyed, and reaches positioning LED lamp bead 12 at a distance from light guide plate 8, to realize
The ultra-narrow frame or Rimless LCD TV of side-light type or the ultra-narrow frame or Rimless of liquid crystal display position light guide plate mode.
In summary：Using in the display or display device of the present invention program, filled using protective cover is increased in lamp bar 1
It sets to protect LED lamp bead 12 and positioning light guide plate 8, the LED lamp bead 12 in lamp bar 1 can be protected not by light guide plate to realize
8 squeeze, and can be accurately positioned light guide plate 8 and 12 gap of LED lamp bead, thus effective solution the problems of the prior art.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
