A pumping rod is inserted at the both ends for determining frame respectively, and pumping rod one end stretches out in outside, and the other end is inserted in emitting cavity, pumping rod
Inserting end is vertically arranged a drag hook, is packed into a light-emitting device between two drag hooks, light-emitting device include one piece or more of connecting plate with
And luminous lamp bead, it is rotatablely connected by hinge between each connecting plate, shape is in an angle between adjacent two connecting plate.
The bottom of the light guide plate faces light-emitting device and is provided with more than one leaded light as a preferred technical solution,
Cavity, the leaded light cavity face the angle between two connecting plates.
A shackle is respectively set in the both ends of the light-emitting device as a preferred technical solution, and one is provided among shackle
Mounting hole, drag hook are inserted in mounting hole.
As a preferred technical solution, described one piece or more of connecting plate with respect to light guide plate side be both provided with one layer it is reflective
Layer.
The external of pumping rod is set with a silica gel sheath as a preferred technical solution, and silica gel sheath insertion is installed on outer fixed frame
In, pumping rod passes through silica gel sheath.
The utility model has the beneficial effects that：The utility model is simple in structure, and using the mounting means of straight-down negative, shine dress
The length set can be adjusted according to the model of backlight, and the angle between two connecting plates can also require to be adjusted according to light extraction
Section, and connecting plate inner end is provided with reflective layer, and the light that luminous lamp bead is sent out is reflected by reflective layer and is spread so that light extraction
Can be more uniform, the light dark space between adjacent two luminous lamp bead is reduced, overall brightness is improved.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other drawings may also be obtained based on these drawings.
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the structural schematic diagram of the pumping rod of the utility model.
Specific implementation mode
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As depicted in figs. 1 and 2, including an outer fixed frame 2, be packed into a light guide plate 1 among outer fixed frame 2, light guide plate 1 with it is outer
There are one emitting cavities for setting between 2 inner wall of fixed frame, and a pumping rod 11, pumping rod 11 1 are inserted into the both ends of outer fixed frame 2 respectively
End stretches out in outside, and the other end is inserted in emitting cavity, and the inserting end of pumping rod 11 is vertically arranged a drag hook 7, between two drag hooks 7
It is packed into a light-emitting device, light-emitting device includes one piece or more of connecting plate 6 and luminous lamp bead 8, passes through hinge between each connecting plate 6
Chain 5 is rotatablely connected, and shape is in an angle between adjacent two connecting plate 6.
Wherein, the bottom of light guide plate 1 faces light-emitting device and is provided with more than one guide-lighting cavity 4, and guide-lighting cavity 4 is just
