The depth of the sinking groove 420 may be less than the height of the branch part 413, or may be equal to the height of the branch part 413, and when the depth of the sinking groove 420 is equal to the height of the branch part 413, the light supplement lamp bead 600 is equivalently directly disposed on the bottom plate 411.
The light-emitting surface of light filling lamp pearl 600 and the light-emitting surface of lamp pearl on lamp plate 331 are at same horizontal plane, and the distance between light filling lamp pearl 600 and the lamp pearl on lamp plate 331 and optical diaphragm 310 is equal, so the uniformity of luminance can be guaranteed.
Further, the support main body of the lamp panel support 400 is made of an elastic material, and the elastic material includes a rubber material.
When the lamp panel 331 is used, under the condition that the lamp panel 331 deforms due to expansion with heat and contraction with cold, the lamp panel support 400 is made of an elastic material, so that stress generated by deformation of the lamp panel 331 can be effectively absorbed by the lamp panel support 400 and converted into elasticity, and the lamp panel 331 is effectively prevented from being broken; and after the lamp panel 331 deforms and displaces, the lamp panel 331 can return to the original position through elastic recovery of the lamp panel bracket 400.
As shown in fig. 4, heat dissipation holes 430 are formed in the bottom of the mounting groove 410, the area of each heat dissipation hole 430 is smaller than the area of the bottom of the mounting groove 410, heat conducting glue is disposed at the position, corresponding to the heat dissipation holes 430, of the lamp panel 331, and the backboard 320 and the lamp panel 331 are bonded by the heat conducting glue.
The number of the heat dissipation holes 430 may be only one, when there is one heat dissipation hole 430, the distance from the edge of the heat dissipation hole 430 to the branch portion may be just used for setting adhesive, and the shape of the heat dissipation hole 430 is the same as the shape of the groove bottom of the mounting groove 410 and is coaxial.
Thus, when the lamp panel 331 needs to be reworked and disassembled, the lamp panel 331 and the lamp panel bracket 400 can be taken down from the backboard together, and then the adhesive between the lamp panel 331 and the lamp panel bracket 400 is cut off through the heat dissipation holes 430, so that the lamp panel 331 can be taken down easily, and the situation of fragment is not easy to occur when the lamp panel 331 needs to be reworked and disassembled; of course, the heat dissipation hole 430 may be provided in plurality.
Moreover, as shown in fig. 3, this application can also be provided with the heavy groove 321 of support in the position that backplate 320 corresponds lamp plate support 400, and the heavy groove 321 of support is corresponding with lamp plate support 400 shape, sets up lamp plate support 400 in the heavy groove 321 of support for lamp plate 331 can be through direct and backplate 320 contact of louvre 430, directly conducts the heat that lamp plate 331 sent to backplate 320 on, dispel the heat to lamp plate 331, for the scheme that sets up the heat-conducting glue, through the heavy groove 321 of support, make lamp plate 331 and backplate 320 direct contact's scheme, carry out the more economical and practical that dispels the heat.
In this embodiment, a first contact 510 is further disposed on the bottom plate 411, the first contact 510 is electrically connected to the adjacent light-compensating lamp bead 600, a second contact is disposed on the back of the lamp panel 331 at a position corresponding to the first contact 510, and the second contact and the lamp bead on the lamp panel 331 are electrically connected to the same driver.
After lamp plate 331 is installed on lamp plate support 400, second contact on lamp plate 331 can with lamp plate support 400 on first contact 510 electric conduction, realize the effect of lamp pearl on lamp plate 331 and the synchronous work of light filling lamp pearl 600 on lamp plate support 400 for light transition between adjacent lamp plate 331 is more even, the problem that the light of light filling lamp pearl 600 is dark or bright for the lamp pearl on lamp plate 331 can not appear.
Example two:
as shown in fig. 8, as the second embodiment of this application, disclose a backlight module 30, different from the first embodiment, lamp plate support 400 in backlight module 30 of this embodiment includes bottom plate 411 and a plurality of lamp pearl base, lamp pearl base sets up on the bottom plate 411, bottom plate 411 and lamp pearl base integrated into one piece set up.
And it is a plurality of the lamp pearl base is the strip and arranges and form spacing area, many spacing area is violently indulged staggered arrangement, forms a plurality of that latticed distributes mounting groove 410, lamp plate 331 edge corresponds the position of lamp pearl base is provided with draw-in groove 332, light filling lamp pearl 600 sets up on the lamp pearl base, lamp plate 331 sets up on the bottom plate 411, lamp plate 331's draw-in groove 332 with lamp pearl base block.
At lamp plate 331 continuous during operation, generate heat and can lead to the stickness variation of the viscose between lamp plate 331 and the lamp plate support 400, carry out spacing block through draw-in groove 332 at lamp plate 331 edge and lamp pearl base, carry on spacingly to lamp plate 331, prevent effectively that lamp plate 331 from taking place the condition of aversion.
And for first embodiment, lamp plate support 400 in this embodiment can make the distance between light filling lamp pearl 600 and the lamp plate 331 on the lamp plate 331 equal with the distance of adjacent lamp pearl on the lamp plate 331, improves the luminous homogeneity of concatenation lamp plate 330 face.
Wherein, the height of lamp pearl base in this embodiment with lamp plate 331's thickness is the same, light filling lamp pearl 600 with lamp plate 331 on the lamp plate 331 is located the coplanar, the luminous homogeneity of further improvement concatenation lamp plate 330's face.
As shown in fig. 9, the shape of draw-in groove 332 of lamp plate 331 with the shape looks adaptation of lamp pearl base, the lamp pearl base includes first base 620 and second base 630, first base 620 is located two that crisscross each other the intersect department in spacing area, four angles of first base 620 are provided with the breach respectively, form cruciform structure, the apex angle of lamp plate 331 corresponds the breach of first base 620.
The second base 630 corresponds to the side of the lamp panel 331, and the second base 630 is square.
Simply put, for example, when the quantity of lamp plate 331 is four in concatenation lamp plate 330, and four lamp plates 331 are "tian" font setting, then the shape that corresponds the lamp pearl base of four lamp plate 331 intermediate positions department is the structure of "ten" shape, carries on spacingly to four lamp plates 331 simultaneously.
