Abstract
The present invention relates to an improvement on a support of a back light module. A surface of a back light module, which faces a lamp casing, is provided with a plurality of protruded supporting elements which are integrally formed, and the protruded length of each supporting element is corresponding to the distance between the bottom of the lamp casing and a diffuser plate. When the diffuser plate is covered on the lamp casing, the supporting elements are butted on the bottom of the lamp casing.
Description
Technical field
The present invention is the improvement that a kind of module backlight supports, and referring to a kind of especially is the structural design that supports by being shaped in the diffuser plate support member of face in addition so that it can replace lampshade, can arrive the effect of saving cost and effectively supporting via enforcement of the present invention.
Background technology
In display device, belong to indispensable assembly by module backlight, but it is that the open end of this lampshade or lamp housing then links a diffuser plate in lampshade or lamp housing inside fixed lamp tube usually.
Existing structure, be as shown in Figure 1, but it is by a lamp housing A inside fixed lamp tube B, the top then is diffuser plate C, this mode there is no support because ask diffuser plate C and lamp housing A bottom, be with because the influence of the material weight of diffuser plate own and environment temperature and humidity can cause the sagging to central part of plate body.
And as shown in Figure 2, be in the bottom of lamp housing A, hang down and establish some support member D that this support member D then can replace diffuser plate C, because this support member D hangs down with screw-in version to being located at lamp housing A, so except the assembly cost height, occasion is set, the homogeneous of the length of then highly or upward dashing forward in many, also become another difficult problem, be with, how to obtain smooth diffuser plate, be a big problem for module backlight.
Summary of the invention
Supervise in this, the applicant is this in being engaged in the experience of display device research and development with production and marketing all the year round, concentrates on studies, and the phase can overcome above-mentioned shortcoming, through exploring repeatedly, start bright go out " improvement that module backlight supports " of the present invention.The improvement that the object of the present invention is to provide a kind of module backlight to support, it can reach the effect of saving cost and effectively supporting.
The improvement that a kind of module backlight of the present invention supports, it is characterized in that, its be in diffuser plate on the face of lamp housing, be provided with some one-body molded outstanding support members, the evagination length of this support member, corresponding to the distance between lamp housing bottom and diffuser plate, so that after diffuser plate was covered on lamp housing, respectively this support member can be replaced the lamp housing bottom.
Support member wherein is perpendicular to diffuser plate.
Support member wherein is the material road moulding of the feeding mouth during for extrusion modling.
Diffuser plate wherein is to be the acryl material.
Description of drawings
For further disclosing concrete technology contents of the present invention, be described in detail as follows below in conjunction with embodiment and accompanying drawing, wherein:
Fig. 1 is existing unsupported synoptic diagram;
Fig. 2 is the existing synoptic diagram that the non-one of support member is linked to lamp housing;
Fig. 3 is a three-dimensional exploded view of the present invention;
Fig. 4 is of the present invention group of upright back synoptic diagram.
Embodiment
As shown in Figures 3 and 4, basically, module backlight of the present invention is combined by a lamp housing 1 and a diffuser plate 2.
Wherein, lamp housing 1 is for existing, and is good with metal material, and only not as limit, it can have a concavo-convex groove shape, so that for the ccontaining location of fluorescent tube (not shown), only this is existing skill, so not as limit.
And of the present invention being different from existingly is, diffuser plate 2, as shown in the figure, on the one side of the low beam shell 1 of this diffuser plate 2, one-body molded prominent some support members 21 of establishing, the height of this support member 21 (or outstanding length), then corresponding to the degree of depth of lamp housing 1, that is, when cover group upright after, respectively this support member 21 is to replace the bottom of lamp housing 1, be with, respectively this support member 21 can be isometric (or contour) by mould design, and its can design via mould the time in the remaining mode in the material road of charging aperture for it, that is promptly become finished product after the extruding.
Embodiment
Please consult accompanying drawing again, the present invention is for as shown in Figure 4 after group is upright, diffuser plate 2 itself since the support with support member 21 with replace, therefore, promptly can be constant smooth and do not have an anxiety of distortion.
So it can make diffuser plate 2 tool good supporting to prevent distortion in not adding under any operation via enforcement of the present invention, can be rated as a quantum jump of module backlight.
Disclosed, be a kind of of preferred embodiment, the change of every part or modification and come from technological thought of the present invention and be have the knack of this technology the people was easy to know by inference, all do not take off patent right category of the present invention.
Claims (4)
1. improvement that module backlight supports, it is characterized in that, its be in diffuser plate on the face of lamp housing, be provided with some one-body molded outstanding support members, the evagination length of this support member, corresponding to the distance between lamp housing bottom and diffuser plate, so that after diffuser plate was covered on lamp housing, respectively this support member can be replaced the lamp housing bottom.
2. the improvement that module backlight as claimed in claim 1 supports is characterized in that support member wherein is perpendicular to diffuser plate.
3. the improvement that module backlight as claimed in claim 1 supports is characterized in that, support member wherein is the material road moulding of the feeding mouth during for extrusion modling.
