Specific embodiment
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, described embodiment is only the utility model section Example, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute under that premise of not paying creative labor
The every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figures 1 and 2, in order to solve since light source is adhered fixed on structural member on traditional backlight source structure,
In rework process, the problem of being easily damaged back light source structure, and then improve maintenance cost, the present embodiment proposes a kind of convenient for more
The back light source structure of lamp bar is changed, mainly includes light emitting structure 10, light-transmissive film layer 20 and glue frame 30；If 20 quantity of light-transmissive film layer
It is dry, 30 surface of glue frame is set to after superposition；One long side of glue frame 30 is formed with length and the consistent groove 31 of glue frame 30；It shines
The shape of structure 10 and the shape of groove 31 match, and are set in groove 31, and light emitting structure 10 can be along the length of groove 31
It is mobile to spend direction；Wherein, the light that light emitting structure 10 issues is irradiated towards light-transmissive film layer 20.In traditional glue frame in the present embodiment
Groove 31 has been added on 30, has enabled light emitting structure 10 that can be slideably positioned in groove 31, has been reprocessed encountering the needs of light emitting structure 10
In the case where, it can be replaced by sliding light emitting structure 10, it is not necessary to which the integrality for damaging back light source structure is also enabled and more being changed
The difficulty of photo structure 10 substantially reduces.
More specifically, barricade (not indicating in figure) is provided in the present embodiment in glue frame 30；Simultaneously in glue frame 30, also
It is formed with the diaphragm slot using barricade as boundary；The size and light-transmissive film layer 20 of diaphragm slot are consistent, for placing light-transmissive film layer 20；Thoroughly
After light film layer 20 is arranged, barricade is between light-transmissive film layer 20 and light emitting structure 10.In order to guarantee the light of light emitting structure 10
Can with normal transmission, need it is further to the height of barricade limited, the setting of barricade both defines light transmission in the present embodiment
The position of film layer 20, so that the position of light-transmissive film layer 20 be enabled to be kept fixed, back light source structure is able to play its function.
As shown in figure 4, more specifically, light emitting structure 10 includes lampshade 11 and lamp bar 12 in the present embodiment；Lamp bar adherency
In on lampshade 11, the two is enabled not generate the movement of relative position；When lampshade 11 and lamp bar 12 are slided in groove 31, lampshade
11 across barricade and partial occlusion light-transmissive film layer 20.Lamp housing portion blocks light-transmissive film layer 20 in the present embodiment, it is ensured that light transmission
Film layer 20 and the position of glue frame are kept fixed, it is not easy to be fallen off from glue frame, so that it is normal to enable the light of back light source structure transmit.
In the present embodiment, if occurring needing to remove lampshade and lamp bar 12 from backlight, so in the case that light emitting structure 10 reprocesses
Lamp bar 12 is individually removed afterwards and is repaired, in disassembly process, replacement lampshade 11 is not needed if lampshade structure is undamaged, if
Lampshade 11 is impaired, then needs together to replace lamp bar 12 and lampshade 11.
More specifically, iron frame 40 is additionally provided in the present embodiment；Iron frame 40 and glue frame 30 are set on same straight line, are enabled saturating
Light film layer 20, which can clamp, to be set between iron frame 40 and glue frame 30.The setting of iron frame 40 further enhances light-transmissive film layer 20
The fixation set enables light-transmissive film layer 20 not generate the movement in vertical direction and horizontal direction.
Each tunic piece that light-transmissive film layer 20 is specially stacked from bottom to top；Further include in the present embodiment light guide plate and
Reflective membrane；Glue frame 30, diaphragm, light guide plate, reflective membrane and iron frame 40 are sequentially superposed；Each being superposed for tunic piece enables light
Line can constantly reflect, while enhance the brightness of light itself, and the light for enabling back light source structure irradiate meets the present embodiment
In application.
As shown in Figure 2 and Figure 3, in the present embodiment, single led light source should be pasted to the PCB route for being welded in band connection line first
Lamp bar 12 is formed on plate, it is rear to be fixed on the slot medial surface of lampshade 11 by pasting heat-conducting glue；Reflective membrane element passes through stickum
Bound edge light guide plate；Another stickum is attached in light guide plate surface, diffusion barrier, upper layer bright enhancement film and lower layer is successively attached and adds lustre to
Film；It is inserted in glue frame 30 after the above components assemble, then these assembled parts are folded to the back side, fills in silica gel solid
It is fixed, and the light emitting structure 10 organized is inserted into groove 31；Iron frame 40 is put on, can also be locked using fastener, is formed complete
Back light source structure.
In conclusion proposed in the present embodiment it is a kind of enable light emitting structure be slideably positioned on back light source structure, to tie up
Trim the hair photo structure when, do not need disassembly back light source structure, reduce maintenance time, difficulty and expense.
