Abstract
The utility model provides a direct type backlight module with a fixing device. From top to bottom, the direct type backlight module with the fixing device comprises an A layer, a B layer, a diffuser plate, the fixing device, a reflector plate, an LED lamp bar and a back plate. The fixing device comprises a main structure positioned in the middle, extending structures positioned on the two sides of the main structure and arranged at intervals, a positioning structure positioned on the lower side of the main structure and a support pillar structure positioned on the upper side of the main structure. A plurality of screw locking holes are formed in the main structure, the main structure and the extending structures are tightly attached to a light-reflecting surface of the reflector plate in parallel and embedded between the reflector plate and the LED lamp bar through the positioning structure, and the main structure is fixedly connected with the back plate of the backlight module through the screw locking holes and screws. The direct type backlight module with the fixing device can conveniently solve the problems that warping occurs and gluing is difficult to operate in the installation process of an LED printed circuit board and the reflector plate in the direct type backlight module, and the direct type backlight module with the fixing device is easy to assemble, low in cost and even in brightness.
Description
Technical field
The utility model relates to technical field of liquid crystal display, particularly a kind of down straight aphototropism mode set that contains fixture.
Background technology
LED is as a kind of novel environment friendly light source, more and more widely be used in that TV is backlight, in the general illumination, automobile-used illumination.LCD, comprise LCD TV, the inside device module backlight, be used to provide the area source that distributes to the liquid crystal panel uniform luminance, led light source installation site difference, be called, the LED light-emitting area is parallel over against the down straight aphototropism mode set that shows drawing, and the LED light-emitting area vertically shows the side entrance back module of drawing.Side entrance back module advantage is thin thickness, and shortcoming is that quality is heavy, efficiency is low, cost is high, and is generally adopting at present in market; The down straight aphototropism mode set shortcoming is that thickness is thicker, and advantage is that quality is light, efficiency is high, cost is low.Yet present down straight aphototropism mode set, because reflector plate is not easy to install, often adopt the support back frame that reflector plate is at first sticked on LCD, directly with the locking of LED lamp strip adoption screw, cause the LCD efficiency to reduce then, though perhaps reflector plate can be installed in LED lamp bar top, to adopt large tracts of land gluing, the perhaps multi-faceted locking of a plurality of screws, to solve the problem of reflector plate warpage, assembling is complicated, cost is high.
The utility model content
In order to overcome the defective of prior art, the utility model provides following technical scheme:
A kind of down straight aphototropism mode set that contains fixture, it comprises from top to bottom: A layer, B layer, diffuser plate, fixture, reflector plate, LED lamp bar and postnotum, described fixture comprises the agent structure that is positioned at mid portion, be positioned at the extended structure that the agent structure both sides are intervally arranged, the fore-set structure that is positioned at the location structure of agent structure downside and is positioned at the agent structure upside, and several screw lock holes are arranged above the described agent structure; The parallel reflector plate reflecting surface that is close to extended structure of described agent structure, in the middle of location structure embedding reflector plate and LED lamp bar, agent structure is fixedlyed connected with module postnotum backlight by screw lock hole and screw.
Further, described A layer is diffusion sheet or blast sheet; Described B layer is diffusion sheet or blast sheet.
The beneficial effect that the utility model brings is:
1, can conveniently solve problems such as the warpage that occurs during LED printed circuit board (PCB) and reflector plate are installed in the down straight aphototropism mode set, gluing operating difficulties;
2, assembling is simple, cost is low, brightness is even.

The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
As shown in Figures 1 to 4, a kind of down straight aphototropism mode set that contains fixture, it comprises from top to bottom: A layer, B layer, diffuser plate 9, fixture, reflector plate 6, LED lamp bar 7 and postnotum 8, described fixture comprises the agent structure 1 that is positioned at mid portion, be positioned at extended structure 2, the location structure 3 that is positioned at the agent structure downside that the agent structure both sides are intervally arranged and the fore-set structure 4 that is positioned at the agent structure upside, and several screw lock holes 5 are arranged above the described agent structure 1; Described agent structure 1 and extended structure 2 parallel reflector plate 6 reflecting surfaces that are close to, in the middle of location structure 3 embedding reflector plates 6 and LED lamp bar 7, agent structure 1 is fixedlyed connected with module postnotum 8 backlight by screw lock hole 5 and screw.Described A layer is diffusion sheet or blast sheet; Described B layer is diffusion sheet or blast sheet.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
