Detailed description of the invention
Refer to Fig. 1 and Fig. 2, the backlight module 100 of embodiment of the present invention comprises that a backlight module housing 200 and is installed on the LGP 300 in backlight module housing 200.Except above-mentioned LGP 300, this backlight module 100 also comprises the light source, reflector plate, the diffusion sheet that are installed in backlight module housing 200.
Backlight module housing 200 comprises first frame 20, one the 3rd frames 30 of 10, one the second frames and the 4th frame 40.Described the first frame 10, described the second frame 20, described the 3rd frame 30 and described the 4th frame 40 join end to end successively and form described backlight module housing 200.Wherein, described the first frame 10 is parallel to each other with described the 3rd frame 30, and described the second frame 20 is parallel to each other with described the 4th frame 40 and is mutually vertical with described the first frame 10 and described the 3rd frame 30 respectively.
In present embodiment, described backlight module housing 200 is adopted made of plastic, and described the first frame 10, described the second frame 20, described the 3rd frame 30, described the 4th frame 40 structure that is formed in one.
Please refer to Fig. 3, Fig. 4, the first frame 10 of described backlight module housing 200, the second frame 20, the 3rd frame 30, the 4th frame 40 are also formed with to the stage portion 103 of described backlight module housing 200 inner recess.In the time of assembling, the optical modules such as described light source, reflector plate, LGP 300, diffusion sheet enter described backlight module housing 200 according to a graded group, and are bearing on the stage portion 103 of described backlight module.Wherein, contiguous described the first frame 10 of described light source arranges, thereby described the first frame 10 forms the light inlet side of described backlight module housing 200, and the light that described light source sends enters LGP 300 and in the interior propagation of LGP 300 from described light inlet side.Described the second frame 20, the 3rd frame 30, the 4th frame 40 form the reflection side of described backlight module housing 200, when light arrives after the second frame 20, the 3rd frame 30, the 4th frame 40, described the second frame 20, the 3rd frame 30, the 4th frame 40 are reflected back light in LGP 300, to increase the utilization ratio of light.
Described the second frame 20, the 3rd frame 30, the 4th frame 40 also comprise towards the first inner surface 104 of described backlight module housing 200 inside and the second inner surface 105.The first inner surface 104 and the second inner surface 105 lay respectively at the both sides of stage portion 103.The sidewall setting of the corresponding LGP 300 of the first inner surface 104.
In order to reduce the second frame 20, the 3rd frame 30, the 4th absorption of frame 40 to light, increase reflectivity, on the first inner surface 104, be also distributed with optics site 106.In the present embodiment, optics site 106 is dome type site, and optics site 106 is uniformly distributed on whole the first inner surface 104.In other embodiments, its also can disorder distribution on whole the first inner surface 104.
Optics site 106 has increased the area of the first inner surface 104, make can have more area to reflect under unit length, thereby the light that incides the first inner surface 104 can be reflected back toward in LGP 300 more, thereby reduce the second frame 20, the 3rd frame 30, the 4th absorption of frame 40 to light, increased reflectivity.
In other embodiments, optics site 106 also can be distributed on the second inner surface 105 simultaneously.
In a word; those skilled in the art will be appreciated that; above embodiment is only for the present invention is described; and be not used as limitation of the invention; as long as within connotation scope of the present invention, within the appropriate change that above embodiment is done and variation all drop on the scope of protection of present invention.
