Abstract
The invention discloses a side light direct type backlight module. The module comprises a back board, a light guide strip arranged on the back board and a diffusion plate arranged on the upper portion of the light guide strip, wherein the light guide strip comprises a cavity, a net point arranged at the bottom of the cavity and a light source which is arranged on the side of the cavity, the cross section of the cavity is in an arc shape, the light emitted by the light source enters the inside of the cavity, and the light is on the diffusion plate evenly at a certain lighting angle under the coactions of the net point at the bottom of the light guide strip and the arc structure of the light guide strip. The module can emits the light evenly, the light shadow problem in the prior art is solved, and the backlight with good subjective effect is obtained.
Description
Technical field
The present invention relates to the electronic display technology field, relate in particular to a kind of side light inlet down straight aphototropism mode set.
Background technology
Along with China LED LCD TV demand sharply rises violently, the development of LED-backlit module field is swift and violent, add low cost, energy-conservation, the requirements such as performance, straight-down negative 3D all-in-one LED-backlit arises at the historic moment, indicated and had function advanced person (3D, intelligence), with low cost (without LGP, save front frame, backboard etc.), superior performance (brightness uniformity, reliability, heat radiation is better) etc. characteristics backlight, the replacement process of side entering type LED type will be accelerated most probably, and seize energetically side entering type LED market, the television type that forms a new round updates, directly below diffuser plate, cast out for the LED lamp wiring and the straight-down negative structure is most of at present, because cost requirement, a LED lamp number is fewer, and the in addition requirement of thickness, so that the LED lamp shadow is very obvious.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
The technical problem to be solved in the present invention is, for the defects of prior art, provides a kind of side light inlet down straight aphototropism mode set.The present invention is incorporated into light-strip both sides with the LED lamp, allows LED side light inlet through the acting in conjunction of light-strip upside arc and site, bottom, and solving lamp shadow problem of the prior art, thereby it is better backlight to obtain subjective effect.
The technical scheme that technical solution problem of the present invention adopts is as follows:
A kind of side light inlet down straight aphototropism mode set wherein, comprising: backboard, be arranged on light-strip on the backboard, be arranged on the diffuser plate of light-strip top; Described light-strip further comprises a cavity, be arranged on the site of cavity bottom and be arranged on the light source of cavity side, the cross section of described cavity be shaped as circular arc; The light that light source sends enters inside cavity, under the site and the acting in conjunction of light-strip arcuate structure of light-strip bottom, light is certain lighting angle evenly beats on diffuser plate.
Described side light inlet down straight aphototropism mode set, wherein, described light source comprises several LED lamps.
Described side light inlet down straight aphototropism mode set, wherein, described LED lamp is setting up and down.
Described side light inlet down straight aphototropism mode set, in, the number of described light-strip is two, it is arranged side by side on backboard.
A kind of side light inlet down straight aphototropism mode set provided by the present invention, by the LED lamp being incorporated into light-strip both sides, the side light inlet of LED lamp enters into light-strip, allows the at an angle not emission at interval of light, thereby effectively solved the lamp shadow problem, it is better backlight to obtain visual effect.
Description of drawings
Fig. 1 is that a kind of side light inlet down straight aphototropism mode set structure of the present invention is launched schematic diagram.
Fig. 2 is light-strip of the present invention and LED lamp position view.
The specific embodiment
For making purpose of the present invention, technical scheme and advantage clearer, clear and definite, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
The light of LED lamp of the prior art directly casts out from the diffuser plate below, form certain clear zone, because the Cost Problems of LED, the negligible amounts of the LED lamp that generally arranges at light fixture, but the interstitial site between LED lamp and the LED lamp becomes large because of the minimizing of a LED lamp number, the gap becomes the large formation of LED interval location dark space that then directly causes, must be invisible by certain thickness light mixing distance guarantee lamp shadow, and down straight aphototropism mode set of the prior art is difficult to solve the larger problem of its thickness.
A kind of side light inlet down straight aphototropism mode set structure expanded view provided by the invention as shown in Figure 1, wherein, comprising: backboard 10, be arranged on light-strip 20 on the backboard, be arranged on the diffuser plate 30 of light-strip top.
As shown in Figure 2, light-strip of the present invention and LED lamp position view, the number of described light-strip is two, it is arranged side by side on backboard 10.
Described light-strip 20 further comprises a cavity 21, be arranged on the site (not marking among the figure) of cavity bottom and be arranged on the light source of cavity side, the cross section of described cavity 21 be shaped as circular arc; The light that light source sends enters inside cavity, under the site and the acting in conjunction of light-strip arcuate structure of light-strip bottom, light is certain lighting angle evenly beats on diffuser plate 30.
Further, described light source comprises several LED lamps.As shown in Figure 2, described LED lamp 22 is setting up and down, be positioned over the both sides of light-strip, its light that sends enters the inside cavity of light-strip, owing to be provided with the arcuate structure of site and light-strip in the light-strip bottom light is sent at an angle uniformly, thereby can overcome the dark space of horizontal lamp gap location of the prior art fully, and can effectively reduce the thickness of module.
A kind of side light inlet down straight aphototropism mode set provided by the present invention, by the LED lamp being incorporated into light-strip both sides, the side light inlet of LED lamp enters into light-strip, acting in conjunction through light-strip upside arc and site, bottom, allow light at an angle not the interval launch light, thereby effectively solved lamp shadow problem of the prior art, it is better backlight to obtain subjective effect.
Should be understood that application of the present invention is not limited to above-mentioned giving an example, for those of ordinary skills, can be improved according to the above description or conversion that all these improvement and conversion all should belong to the protection domain of claims of the present invention.
