Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the utility model is described, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the amendment of the various equivalent form of values of the present utility model.
The utility model discloses a kind of fixture of diaphragm of LED-backlit module, be illustrated in figure 1 the structural representation of general LED-backlit module, LED-backlit module comprises: glue frame 10, optical diaphragm group 20, diffuser plate 30, reflector plate 40, LED lamp bar 50 and backboard 60, in the present embodiment, optical diaphragm group 20 comprises 3 prismatic lenses, what Fig. 1 illustrated is direct-light type LED backlight module, and the utility model is also used in the LED-backlit module of other types.
In the present embodiment, increase by a fixture 70, this fixture 70 has elasticity, the viscose glue 72,73 that it comprises body 71 and is positioned at the end of body 71, and in the present embodiment, viscose glue is double faced adhesive tape.
In the present embodiment, described body 71 comprises First 711 and with First 711 second 712 connected vertically, a described viscose glue 72 is positioned at the end of First 711, described another viscose glue 73 is positioned at the end of second 712, there is elasticity at First 711 and second 712 junction, also be that body 71 is made up of unlike material, by having, elastomeric material makes in the middle of it.
When use, the viscose glue 72 of fixture 70 one end is pasted in optical diaphragm group 20, the viscose glue 73 of fixture 70 other ends is pasted on the parts of LED-backlit module, in the utility model, the viscose glue 73 of fixture 70 other ends is pasted on and is fixed on glue frame 10, can reach optical diaphragm group 20 is fixed on to the effect in glue frame 10.
When optical diaphragm group is expanded with heat and contract with cold, owing to being made by elastomeric material the centre of fixture 70, the elastic deformation by fixture and then offset expanding with heat and contract with cold of optical diaphragm group, corresponding fixture elastic deformation also can meet the flexible of diaphragm.
As shown in Figure 6, in the time that optical diaphragm group 20 expands, fixture produces elastic deformation in the middle of fixture, thus the expansion of having offset optical diaphragm group.
