Abstract
The utility model discloses a backlight module, which comprises a light guide plate, an LED (Light Emitting Diode) group and a backboard. The LED group is located between the backboard and the light guide plate. The backlight module further comprises a strip-like elastic block which is provided with at least three through holes. Elastic sheets are arranged at the side same with the through holes. The elastic sheets correspond to the through holes and one edge of each elastic sheet is fixedly connected with the wall surfaces of the through holes. The elastic block is fixedly connected inside the backboard, the elastic sheets are contacted with the LED group, and the LED group is fitted with the light guide plate. The backlight module with the structure can eliminate the gap between the LED module and the light guide plate and improves the yield of backlight module products.
Description
Technical field
The utility model relates to a kind of module backlight.
Background technology
As shown in Figure 1; Existing module backlight comprises LGP, LED group (the English full Light Emitting Diode that is, Chinese full name is a light emitting diode, hereinafter to be referred as LED) and backboard; The LED group is between backboard and LGP, and the LED group is fixed on the inboard of backboard through adhesive tape.Because itself there are dimensional tolerance in LED group and LGP parts, cause after the LED group is installed on the backboard, having the gap between LED group and the LGP.Simultaneously, because manpower is installed LGP by hand, there are the different of assembling mode in LED when organizing with backboard, thereby cause the difference in size in the gap between LED group and the LGP.Exist the gap can influence the product optical property of entire aphototropism mould between LED group and the LGP, make it can not satisfy the requirement of product design.
The utility model content
Technical problem:The utility model technical problem to be solved is: a kind of module backlight is provided, to eliminate the gap between LED group and the LGP, improves the qualification rate of module product backlight.
Technical scheme:For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of module backlight comprises LGP, LED group and backboard, and LED organizes between backboard and LGP; Also comprise the bullet piece; This bullet piece is strip, is provided with at least three through holes in the bullet piece, is provided with shell fragment in the same side of through hole; Shell fragment is corresponding with through hole, and one side of shell fragment is fixedly connected with the wall of through hole; The bullet piece is fixedly connected on the inboard of backboard, and shell fragment touches with the LED group mutually, and the LED group is fitted with LGP.
Beneficial effect:Compared with prior art, the technical scheme of the utility model can be eliminated the gap between LED group and the LGP, improves the qualification rate of module product backlight.In the prior art, there is the gap between LED group and the LGP, influences the product optical property of module backlight, make it can not satisfy the requirement of product design.And in the present technique scheme,, utilize the elastic force of shell fragment in the bullet piece through newly-increased bullet piece between backboard and LED group, make shell fragment apply extruding force to the LED group.The LED group moves towards LGP under the effect of this extruding force, and the state that finally keeps LED group and LGP to fit each other.So just eliminate the gap between LED group and the LGP, improved the qualification rate of module product backlight.

Fig. 3 is the vertical view of the bullet piece in the utility model.
Fig. 4 is the front view of the bullet piece in the utility model.
Have among the figure: LGP 1, LED group 2, backboard 3, bullet piece 4, through hole 41, shell fragment 42.
The specific embodiment
To shown in Figure 4, the module a kind of backlight of the utility model comprises LGP 1, LED group 2, backboard 3 and bullet piece 4 like Fig. 2.LED group 2 is between backboard 3 and LGP 1.Bullet piece 4 is strip, is provided with at least three through holes 41 in the bullet piece 4.Through hole 41 is preferably square hole.Square hole is made on the one hand easily, helps fixation spring tab 42 on the other hand.The quantity of the through hole 41 in the length of bullet piece 4 and the bullet piece 4 all can be organized 2 length and decides according to LED.Be provided with shell fragment 42 in the same side of through hole 41.Shell fragment 42 is corresponding with through hole 41, and one side of shell fragment 42 is fixedly connected with the wall of through hole 41.Bullet piece 4 is fixedly connected on the inboard of backboard 3, and shell fragment 42 touches with LED group 2 mutually, and LED group 2 is fitted with LGP 1.
The module increase backlight of this structure is provided with bullet piece 4.When assembling the module backlight of this structure, bullet piece 4 can be fixedly connected on the inboard of backboard 3 through gluing or bolt mode.LED group 2 place with backboard 3 and LGP 1 between, and it is 2 inconsistent that shell fragment 42 and LED in the bullet piece 4 organized.The 42 couples of LED of shell fragment group 2 applies extruding force, and on the one hand, shell fragment 42 self deformation takes place, and promptly shell fragment 2 moves towards through hole 41, and on the other hand, LED group 2 moves towards LGP 1, fits fully with LGP 1 until LED group 2.42 pairs of LED groups 2 of shell fragment apply extruding force, can eliminate the gap between LED group 2 and the LGP 1, improve the product percent of pass of module backlight.
Further, described through hole 41 is delegation to be arranged, and is evenly distributed in the bullet piece 4.Can apply uniform, sufficient extruding force so that be arranged on 42 pairs of LED groups 2 of shell fragment in through hole 41 outsides like this, assurance LED group 2 realizes fitting with LGP 1.In addition, the distance between the adjacent shell fragment 42 is set rationally, can guarantees that also 42 pairs of LED groups 2 of shell fragment apply enough extruding forces.Distance between the adjacent shell fragment 42 is preferably 20 millimeters to 30 millimeters, for example can be 20 millimeters, 25 millimeters, 30 millimeters.
The core of the utility model is, through bullet piece 4 is set on backboard 3, makes can not produce the space between LED group 2 and the LGP 1.The content of the above-mentioned specific embodiment only is the explanation to the present technique scheme.The non-creativeness that any those skilled in the art carry out according to the present technique scheme improves, and all belongs to the protection domain of this patent.
