The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
Referring to Fig. 1, is a kind of backlight module 100 that first embodiment of the invention provides, and it comprises a light source 10, LGP 20 and an optical fiber group 30.
This light source 10 is for emission of light, and comprises a light-emitting area 11.In the present embodiment, described light source 10 is light emitting diode (Light emitting diode, LED).
The plate-like structure that this LGP 20 is formed in one, it comprises an incidence surface 21 and one and this incidence surface 21 exiting surface 22 connected vertically.This incidence surface 21 arranges towards this light-emitting area 11.The light that this light source 10 is launched enters this LGP 20 from this incidence surface 21, and this exiting surface 22 penetrates from this LGP 20 certainly.
On this exiting surface 22, offer multiple rectangular hemispheric grooves 201 of arranging that are.In other embodiments, this groove 201 also can be spherical crown shape.Because light arc reflected directly into described exiting surface 22 run into the groove 201 of indent in the interior transmittance process of described LGP 20 after, the path of the interior light transmission of this LGP 20 is shortened, the energy loss of light reduces, to improve the overall brightness value of described exiting surface 22.
This optical fiber group 30 directly imports this LGP 20 for the light that this light source 10 is launched by this incidence surface 21, and comprises multifiber 30a.Every optical fiber 30a includes the first port 31 and the second port 32 that are oppositely arranged.This first port 31 of this multifiber 30a all directly contacts with this light-emitting area 11, for receiving the light of launching from this light source 10.This second port 32 of this multifiber 30a all directly contacts with this incidence surface 21, and spaced set, makes the light penetrating from this second port 32 can arrive this incidence surface 21, to improve the coupling efficiency of light.In the present embodiment, this optical fiber 30a is generally the highly purified glass material of reeling off raw silk from cocoons, and it provides the transmission path of low loss for light beam, and it also can be heat-resistant plastic optical fiber, and its radius is about below 1000 microns.
The light transmittance process of this backlight module 100 is as follows: the light that this light source 10 is launched enters in the plurality of optical fiber 30a by the plurality of the first port 31, and all constantly carried out total reflection in each optical fiber 30a, to penetrate from the plurality of the second port 32, directly arrive this incidence surface 21, finally interior after multiple reflections at this LGP 20, arrive this exiting surface 22, and undertaken penetrating this LGP 20 after multiple reflections and refraction by the plurality of groove 201.
In other embodiments, because optical fiber 30a can carry out suitable bending, therefore this incidence surface 21 also can not be oppositely arranged with this light-emitting area 11.
In other embodiments, for the light that makes these exiting surface 22 outgoing is uniformly distributed more, can on this incidence surface 21, site be also set.
As shown in Figure 2, be the backlight module 200 that the second embodiment of the present invention provides, this backlight module 200 is with the difference of this backlight module 100: this backlight module 200 comprises two light sources 210 and two optical fiber groups 230.Two light sources 210 of these two optical fiber groups 230 and this are corresponding one by one.Each optical fiber group 230 includes multifiber 230a.The quantity of this optical fiber 230a in these two optical fiber groups 230 can be identical, also can be different.Each this optical fiber 230a includes a first port 231a and a second port 232a.This first port 231a in each optical fiber group 230 all directly contacts with this corresponding light source 210, this second port 232a in each optical fiber group 230 all directly contacts with this incidence surface 221, and the plurality of the second port 232a spaced set in each optical fiber group 230.The minimum spacing of these two optical fiber groups 230 equals the spacing of adjacent two the second port 232a in each optical fiber group 230.
In other embodiments, the quantity of this light source 210 and this optical fiber group 230 is not limited to present embodiment.
Compared with prior art, backlight module of the present invention, is divided into multiple small light sources by the plurality of optical fiber by this light source, is equivalent to increase the lighting area of this light source, makes the distribution of light of this exiting surface outgoing more even.Meanwhile, in the situation that incidence surface area is identical, the usage quantity of light source can be reduced, electric energy can be effectively saved.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
