[specific embodiment]
Below will be with graphic exposure a plurality of embodiments of the present invention, as clearly stated, the details in many practices will be explained in the following description.Yet those of ordinary skill in the art should recognize, in part embodiment of the present invention, the details in the plurality of practice is also non-essential, therefore does not apply to limit the present invention.In addition,, for the purpose of simplicity of illustration, some known habitual structures and element middlely illustrate the mode simply to illustrate graphic.
Fig. 1 illustrates the top view according to the backlight module of an embodiment of the present invention.Fig. 2 illustrates the profile that the backlight module of Fig. 1 cuts open along A-A ' line.As the 1st and Fig. 2 as shown in, in present embodiment, backlight module can comprise framework 100, blooming piece 300 and light source module 400.Framework 100 comprises framework 110 and projection 200.Framework 110 openings 101, and the upper surface of framework 110 has the first inclined plane 111, and a plurality of projections 200 are arranged on the first inclined plane 111.Blooming piece 300 is to be sheathed on projection 200, and blooming piece 300 covers opening 101.Light source module 400 is be arranged at framework 100 belows and be exposed at least in part opening 101, and is positioned at blooming piece 300 belows.Blooming piece 300 has bottom surface 301, and the bottom surface 301 of part is towards the first inclined plane 111.The first inclined plane 111 is that relative bottom surface 301 tilts, and furthermore, the vertical range H of the first 301 of 111Zhi bottom surfaces, inclined plane increases gradually towards opening 101.
In above-mentioned embodiment, because projection 200 is to be arranged on the first inclined plane 111, and the first inclined plane 111 is towards the bottom surface 301 of blooming piece 300 and relative this bottom surface 301 tilts, therefore, when the part light from light source module 400 arrives at the first inclined plane 111, the first inclined plane 111 can be reflected this light towards blooming piece 300, thereby increases the amount of light of projection 200 and blooming piece 300 junctions, to avoid projection 200 too low with the brightness of the junction of blooming piece 300.
In part embodiment, as shown in Figure 2, the upper surface of framework 110 also has the second inclined plane 112.The second inclined plane 112 is to be adjacent to the first inclined plane 111, and the second inclined plane 112 is between the first inclined plane 111 and opening 101.In other words, framework 100 has sequentially the first inclined plane 111 and second inclined plane 112 of adjacency, and the first inclined plane 111 with respect to the second inclined plane 112 away from opening 101.The second inclined plane 112 is towards the bottom surface 301 of blooming piece 300, and is also that relative bottom surface 301 tilts.Thus, not only the first inclined plane 111 can be by the light from light source module 400 towards blooming piece 300 reflections, and the second inclined plane 112 also can be reflected the light from light source module 400 towards blooming piece 300, thereby promotes the light effect that of backlight module.In part embodiment, the slope on the first inclined plane 111 and the second inclined plane 112 can be unequal.For instance, the slope on the second inclined plane 112 can be greater than the slope on the first inclined plane 111, and makes to form slope turning point 113 between the first inclined plane 111 and the second inclined plane 112.More hour, the luminance difference of the left and right sides of slope turning point 113 is less, thereby makes the bright dipping of backlight module more even for slope difference between the first inclined plane 111 and the second inclined plane 112.
In part embodiment, as shown in Figure 2, projection 200 is first inclined planes 111 of out of plumb ground connecting frame 100.Specifically, projection 200 has sidewall 201.The first inclined plane 111 of sidewall 201 connecting frames 100 of projection 200, sidewall 201 and the first inclined plane 111 out of plumb.In other words, the first inclined plane 111 is that the sidewall 201 of relative projection 200 tilts.In addition, the sidewall 201 of projection 200 is in fact perpendicular to the bottom surface 301 of blooming piece 300.
Thus, when blooming piece 300 is sheathed on projection 200, the bottom surface 301 of blooming piece 300 and the first inclined plane 111 of framework 110 gap that can be separated by, arrives at the first inclined plane 111 for light through this gap, and by the first inclined plane 111 towards blooming piece 300 reflections.
In part embodiment, as shown in Figure 2, blooming piece 300 has end face 302 and through hole 303.Bottom surface 301 is relative with end face 302, and through hole 303 is through between bottom surface 301 and end face 302.Blooming piece 300 can be sheathed on projection 200 by through hole 303.Furthermore, projection 200 can insert through holes 303 from bottom surface 301, and from end face 302 passes through hole 303, and make blooming piece 300 thereon sheathed.In part embodiment, the sectional area of through hole 303 can equate in fact with the sectional area of projection 200, so that projection 200 closely supports and closes with the hole wall of through hole 303, to prevent that blooming piece 300 from moving relative to projection 200, thereby be beneficial to fixed optics diaphragm 300.
In part embodiment, as shown in Figure 2, light source module 400 is side entering type light source.Specifically, light source module 400 can comprise light source 410 and LGP 420.LGP 420 is to be exposed at least in part opening 101, and is positioned at blooming piece 300 belows.Light source 410 be a wherein side of LGP 420 and be located in framework 100 and LGP 420 between, and without being exposed to opening 101.Say further, LGP 420 can have incidence surface 422 and exiting surface 424, and incidence surface 422 is adjacent with exiting surface 424, and exiting surface 424 is to be exposed at least in part opening 101, and light source 410 is to be positioned at incidence surface 422 sides.
Thus, when light source 410 starts, it can ray, and this light can be entered by the incidence surface 422 of LGP 420 in LGP 420, and is passed to opening 101 by exiting surface 424, then enters in blooming piece 300.
In part embodiment, as shown in Figure 2, the framework 100 of part, around light source module 400, so that light source module 400 is in the inner spacing, and avoids light source module 400 to move arbitrarily.Specifically, the framework 110 of framework 100 can comprise side frame body 120.Side frame body 120 is around LGP 420, and light source 410 is between side frame body 120 and LGP 420.In other words, side frame body 120 is around accommodation space S, and light source 410 is all placed in accommodation space S with LGP 420.Thus, side frame body 120 can be limited in light source 410 and LGP 420 in accommodation space S.
In part embodiment, framework 110 also comprises top framework 130.Top framework 130 is to be arranged on side frame body 120.Top framework 130 covers light source 410 and LGP 420 partly.The first inclined plane 111 and the second inclined plane 112 are the upper surface of top framework 130, and opening 101 is around forming by 130 of top frameworks.Whereby, top framework 130 can be covered light source 410, and enters in blooming piece 300 by opening 101 for the part light in LGP 420.
