Abstract
The utility model discloses an LED (Light Emitting Diode) backlight module, which comprises a fixing frame, a back plate, a reflecting sheet, an LED lamp bar, a diffusion sheet and an optical film, wherein the LED lamp bar is arranged in the fixing frame; the reflecting sheet and the back plate are arranged in sequence along the light-emitting direction of the LED lamp bar; the diffusion sheet and the optical film are arranged in sequence along the backlight direction of the LED lamp bar; fine radiating fins are uniformly distributed on the LED lamp bar; the optical film is provided with a micro prism lens. Compared with the prior art, the LED backlight module has the advantage that the LED lamp bar is arranged reversely, and the light-emitting direction faces a mirror reflecting part, so that the distance between emitted light rays and the diffusion sheet is increased, and the concealment of a lamp is not influenced; the micro prism lens is arranged on the optical film, so that the diffusion effect of the backlight is enhanced, and the backlight is more uniform; due to the arrangement of the radiating fins on the LED lamp bar, the heat-dissipating efficiency of the entire module is increased, and the working stability of the module is enhanced.
Description
Technical field
The utility model relates to the backlight module field, is specially a kind of LED-backlit module.
Background technology
From the classification of light source, divide, backlight module can be divided into the CCFL backlight module, LED-backlit module etc.The LED-backlit module divides and can be divided into the direct-light type LED backlight module according to the LED position, and LED side backlight module.In general, side liquid crystal module backlight is used in small-medium size, and large scale application end backlight module.Usually side backlight due to light source in side, generally all thinner, and the end backlight due to backlight in bottom, so in general the end backlight all thicker.Can backlight module be all emphasized a disguise, disguised just for watching from liquid crystal display, see an important indicator of lamp shadow.Usually lamp is far away apart from diffusion sheet, and disguise is better, nearer apart from diffusion sheet, and disguise is poorer.In order to realize better disguise, common implementation method is all the diffusion sheet of selecting mist degree larger, when but the diffusion sheet mist degree is large, permeability is just poor, therefore the light utilization efficiency of light source can be lower, if use intensive LED lamp bar, can cause the heat dispersion of backlight module to reduce, affect the operating efficiency of backlight module.
The utility model content
The technical problem that the utility model solves is to provide a kind of LED-backlit module, to solve the problem in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of LED-backlit module, comprise fixed mount, backboard, reflector plate, LED lamp bar, diffusion sheet, blooming, described LED lamp bar is arranged in fixed mount, go out direction of light along LED lamp bar and set gradually reflector plate and backboard, set gradually diffusion sheet and blooming in LED lamp bar direction backlight, described LED lamp bar is provided with equally distributed tiny fin, and described blooming is provided with mini-prism plate.
Further, described blooming and mini-prism plate fit tightly.
Further, described LED lamp bar can many group patterns.
Compared to prior art, LED-backlit module of the present utility model by the anti-dress of LED lamp bar and bright dipping towards this mirror-reflection section, can form a mirror image in the inside of mirror-reflection section, mirror image can be regarded a light source as, increased the distance between emergent ray and diffusion sheet, therefore can suitably reduce the distance between diffusion sheet and lamp, and can not have influence on the disguise of lamp, the mini-prism plate arranged on blooming has been strengthened diffusion effect backlight, make backlight more even, fin on LED lamp bar makes the radiating efficiency of whole module improve, increased the stability of module work.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of LED-backlit module, comprise fixed mount 8, backboard 1, reflector plate 2, LED lamp bar 3, diffusion sheet 5, blooming 6, described LED lamp bar 3 is arranged in fixed mount 8, goes out direction of light along LED lamp bar 3 and has set gradually reflector plate and backboard, in LED lamp bar 3 directions backlight, has set gradually diffusion sheet 5 and blooming 6, described LED lamp bar 3 is provided with equally distributed tiny fin 4, and described blooming 6 is provided with mini-prism plate 7.
Further, described blooming 6 fits tightly with mini-prism plate 7.
Further, described LED lamp bar 3 can many group patterns.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
