Description
Technical field
The utility model relates to back light source technique field, is specially a kind of side-mounted backlight assembly.
Background technology
Backlight is in field extensive application such as liquid crystal display (LCD), advertising lamp box, indoor and outdoor lighting.Place the difference in orientation according to light source, backlight can be divided into straight-down negative and side-mounted two types, straight underFormula backlight, is also referred to as direct-lit backlight, refers to light source is placed on to liquid crystal panel, pervasion componentOr the below of lamp house cloth, direct illumination, light is penetrated from light source (fluorescent tube, light emitting diode (LED) etc.)Go out through reflector reflection, upwards after pervasion component, penetrate from front, illuminate order with the form of area sourceMark, existing direct-light-type backlight, because light source accommodation space is larger, can be according to the size of backlightUse the more light source of number, its advantage is that high brightness, visual angle are good, light utilization efficiency is relatively high, structureSimple etc., but existing direct-light-type backlight has the longitudinally shortcoming such as thick, size is large, difficult mixed light of system,Be mainly used in the less demanding LCD TV of compactedness, thicker advertising lamp box and ceiling light etc. In addition,In prior art, the performance of backlight of LCD sharply declines, its light sending ripple in high temperature rangeLong unstable, colourity is unintelligible, and the service efficiency demand that can not conform, and, need to provide for this reasonNew backlight of LCD overcomes the problems referred to above, therefore, how to design mixed light foot, light is sharpThe side-mounted backlight assembly high by rate, size is little becomes those skilled in the art's problem demanding prompt solution.
Utility model content
The purpose of this utility model is to provide a kind of side-mounted backlight assembly, to solve above-mentioned background skillThe problem proposing in art.
For achieving the above object, the utility model provides following technical scheme: a kind of side-mounted backlight groupPart, comprises the first reflectance coating, light source, LGP, upper diffusion barrier, bright enhancement film, lower diffusion barrier, shadingPaper, the second reflectance coating, described light source is arranged on the first reflectance coating, and the first reflectance coating is arranged on LGPOne side, described LGP bottom is provided with the second reflectance coating, and described light-shielding sheet is arranged on LGP, instituteState diffusion barrier and be arranged on LGP top, described bright enhancement film is arranged on diffusion barrier bottom, described lower diffusionFilm is arranged on bright enhancement film bottom.
Preferably, described bright enhancement film is provided with the prism pattern of homogeneous.
Preferably, described light source becomes cylindrical shape.
Preferably, described upper diffusion barrier and lower diffusion barrier adopt straight-down negative to be arranged on LGP.
Preferably, on described the first reflectance coating and the second reflectance coating, be provided with and regulate the uniform micro-structural of bright dipping.
Compared with prior art, the beneficial effects of the utility model are: the leading of this side-mounted backlight assemblyTabula rasa adopts spectrophotometry to combine with digital UV printing technology and at constant temperature, constant humidity, dustless ringUnder the condition of border, be made, have ultra-thin, superbright, leaded light evenly, energy-saving and environmental protection, no dark space, resistance toWith, be difficult for the distinguishing feature such as yellow, installation and maintenance simple and fast, by LGP, be provided with firstReflectance coating and the second reflectance coating, the light that the LGP back side or the light source back side are transmitted is reflected back in assembly,The loss of the light that light source can be sent is limited in minimum degree, thereby improves the utilization rate of light, increasesFront face brightness is dyed, by upper diffusion barrier and the overlapping use of lower diffusion barrier, by line source (CCFL) and spot light(LED) be converted into a uniform area source by refraction, reflection and the scattering of light, can reach just higherFace brightness effects, simultaneously by the micro-structural being provided with on the first reflectance coating and the second reflectance coating, canAdjust uniform light, make mixed light foot, by the light-shielding sheet being provided with on LGP, can be effectivelyPrevent that light from leaking, by being arranged on the bright enhancement film between upper diffusion barrier and lower diffusion barrier, can be by visual angleOuter unemployed light, is followed according to the reflection effect again of light, and simple in structure, reasonable in design, low energyConsume and be easy to promote the use of.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure: on 1 first reflectance coating, 2 light sources, 3 LGPs, 4, add lustre to paper, 6 times of diffusion barrier, 5 expandsLoose film, 7 light-shielding sheets, 8 second reflectance coatings.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technology in the utility model embodimentScheme is clearly and completely described, and obviously, described embodiment is only one of the utility modelDivide embodiment, instead of whole embodiment. Based on the embodiment in the utility model, this area is commonTechnical staff is not making the every other embodiment obtaining under creative work prerequisite, all belongs to thisThe scope of utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of side-mounted backlight assembly, bagDraw together the first reflectance coating 1, light source 2, LGP 3, upper diffusion barrier 4, bright enhancement film 5, lower diffusion barrier 6, hideMachine-glazed paper 7, the second reflectance coating 8, described light source 2 is arranged on the first reflectance coating 1, and the first reflectance coating 1 is pacifiedBe contained in LGP 3 one sides, described LGP 3 bottoms are provided with the second reflectance coating 8, and described light-shielding sheet 7 is pacifiedBe contained on LGP 3, described upper diffusion barrier 4 is arranged on LGP 3 tops, and described bright enhancement film 5 is installedIn diffusion barrier 4 bottoms, described lower diffusion barrier 6 is arranged on bright enhancement film 5 bottoms.
