The lamp bead of lamp plate and one or more, the positive and negative polar curve of each lamp bead are separately connected the positive and negative anodes pin on lamp plate, and one or more
Lamp bead be fixedly installed on an elastic webbing, one end of elastic webbing passes through the opening of light source box side and stretches out in light source box
The extension end of outside, the elastic webbing passes through a regulating mechanism stationary positioned.
One extension of setting is respectively protruded in the outer openings two sides of the light source box as a preferred technical solution, adjusts machine
Structure uses two positioning screws, and positioning screw spiral is installed in the screw hole on extension, and two positioning screws are oppositely arranged, bullet
Property band extension end pass through and two positioning screws and be fixed by the positioning screw of two sides.
The inner end of elastic webbing, which is screwed, as a preferred technical solution, is installed in a fixing seat, fixed
Seat is screwed on the inner wall for being installed on installation cavity.
One piece or more of reflector, every piece of reflector are equidistantly bonded on the elastic webbing as a preferred technical solution,
On be respectively mounted a lamp bead, the positive and negative anodes pin of lamp bead passes through luminescent screen and elastic band connection lamp plate.
The positive and negative anodes pin of the lamp bead is provided with one section of spring section as a preferred technical solution,.
The beneficial effects of the utility model are: the backlight of the utility model, lamp bead with respect to light guide plate incident angle with
And the spacing between lamp bead can quickly be adjusted, and can be rapidly performed by adjusting when using in the later period according to actual needs,
Use scope can be wider.
Detailed description of the invention
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, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the partial enlargement diagram in Fig. 1 at A.
Specific embodiment
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 shown in Figure 1, including a light source box 4, light guide plate 8, the installation cavity with a side opening in light source box 4 is led
8 side of tabula rasa is partially loaded in installation cavity, and a light source assembly is installed in installation cavity, and the light-emitting surface of light source assembly faces side
Light guide plate 8 be arranged；
Light source assembly includes the lamp bead 5 of a lamp plate 2 and one or more, and the positive and negative polar curve 9 of each lamp bead 5 is separately connected lamp
Positive and negative anodes pin on plate 2, one or more lamp bead 5 are fixedly installed on an elastic webbing 3, and one end of elastic webbing 3 passes through light
The extension end of the opening 7 of 4 side of source capsule and the outside for stretching out in light source box 4, elastic webbing 3 passes through a regulating mechanism stationary positioned.
As shown in Fig. 2, one extension 11 of setting is respectively protruded in the outer openings two sides of light source box, regulating mechanism is fixed using two
Position screw rod 12,12 spiral of positioning screw are installed in the screw hole on extension 11, and two positioning screws 12 are oppositely arranged, elastic webbing
3 extension end passes through two positioning screws 12 and is fixed by the positioning screw 12 of two sides, and the inner end of elastic webbing 3 passes through
