According to one embodiment of present invention, described protuberance is formed by stretching out with exiting surface perpendicular side of described LGP.
According to one embodiment of present invention, described protuberance comprises a first side and connects first side and two Second Edges of LGP side, and described light-emitting component is along described first side and Second Edge one of them arrangement at least.
According to one embodiment of present invention, described first side is parallel to the side that protuberance is set of described LGP, and described Second Edge tilts to connect described first side and the described side that protuberance is set.
According to one embodiment of present invention, described protuberance is " (" shape.
According to one embodiment of present invention, described light-emitting component is located at the outside of backboard.
According to one embodiment of present invention, described light-emitting component comprises some light emitting diodes, and described light emitting diode is arranged along the side of described protuberance.
According to one embodiment of present invention, described backlight module also comprises four sides being located at LGP and the some reflection bars between backboard.
According to one embodiment of present invention, described reflection bar comprises silver slurry reflection bar and white reflection bar, described silver slurry reflection bar is located at the two ends of the side relative with protuberance of LGP, and described white reflection bar is located at other zones outside the setting area of desilver slurry reflection bar of LGP.
The present invention protrudes out backboard by the protuberance that makes LGP, and makes light-emitting component along the protuberance setting, makes in backlight module of the present invention light-emitting component be located at the outside of backboard, and has reduced to be subjected to the impact of light conducting board from deformation.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, and for above and other purpose of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and the cooperation accompanying drawing, be described in detail as follows.
Description of drawings
Figure 1 shows that the perspective exploded view of backlight module of the present invention.
Fig. 2 is the schematic diagram of LGP and light-emitting component in Fig. 1.
Figure 3 shows that the enlarged diagram of Fig. 2 centre circle III.
The specific embodiment
Reach for further setting forth the present invention technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to the specific embodiment of the present invention, structure, feature and effect thereof, be described in detail as follows.
Figure 1 shows that the perspective exploded view of backlight module of the present invention.As shown in Figure 1, backlight module 100 of the present invention is the side-light backlight module, and it comprises backboard 110, LGP 120, light-emitting component 130 and reflection bar 140.
Wherein, backboard 110 is a rectangle framework, and its middle part is provided with the receiving space 111 of accommodating LGP 120 and reflection bar 140.LGP 120 and reflection bar 140 are located in the receiving space 111 of backboard 110, and reflection bar 140 is located between four sides and backboard 110 of LGP 120.Light-emitting component 130 is located at LGP 120 1 sides, and is positioned at the outside of backboard 110.
See also Fig. 2 and Fig. 3, the LGP 120 in the present invention is a male type LGP 120.This LGP 120 has a protuberance 121 that stretches out and form with exiting surface perpendicular side by LGP 120.This protuberance 121 can match with the base of television set or lamp box, as the backlight of showing LOGO, perhaps only as appearance member.The corresponding protuberance 121 of backboard 110 is provided with opening 112, and protuberance 121 protrudes out backboard 110 by this opening 112.
Particularly, the protuberance 121 of LGP 120 is roughly that " (" shape, it comprises a first side 121a who parallels with the side that protuberance 121 is set of LGP 120 and is connected first side 121a and the Second Edge 121b of two inclinations of the side that protuberance 121 is set of LGP 120.Above embodiment only lists wherein a kind of shape of protuberance 121, and understandable, the shape of protuberance 121 is not limited to this.Light-emitting component 130 in the present invention comprises some light emitting diodes, and these light emitting diodes are arranged along one of them side of protuberance 121.That is to say, light-emitting component 130 is along the first side 121a of protuberance 121 and one of them arrangement at least in Second Edge 121b.The arrangement mode of light-emitting component 130 can be evenly distributed, and is also can right and wrong evenly distributed.Interval between adjacent light-emitting component 130 can be adjusted according to the quantity of light-emitting component 130, arrangement mode and the spread length on protuberance 121 of light-emitting component 130.
In the present invention, reflection bar 140 comprises some reflection bars of being located at 120 4 sides of LGP, and these reflection bars 140 can comprise silver slurry reflection bar 141 and white reflection bar 142.In order to reduce the cost of backlight module 100, silver slurry reflection bar 141 can be located at the emphasis reflector space, for example, the two ends of the side relative with protuberance 121 of LGP 120, white reflection bar 142 can be located at other zone except the emphasis reflector space.Certainly, reflection bar 140 of the present invention also can only comprise silver slurry reflection bar 141 or only comprise white reflection bar 142.
The present invention is by being arranged to LGP 120 mode of male type LGP 120, make the protuberance 121 of LGP 120 protrude out backboard 110, and make light-emitting component 130 arrange along protuberance 121, make in backlight module 100 of the present invention light-emitting component 130 be located at the outside of backboard 110, and reduced to be subjected to the impact of LGP 120 distortion.Secondly, backlight module 100 of the present invention and light-emitting component 130 are located at the backlight module 100 of backboard 110 inside and are compared, light-emitting component 130 diminishes with the contact length of LGP 120, and reduced the length of the part LGP 120 that can expand, further reduced the impact that light-emitting component 130 is subjected to LGP 120 distortion.And backlight module 100 of the present invention can significantly reduce the quantity of light-emitting component 130, effectively reduces the light source cost.
Further, in backlight module 100 of the present invention, light-emitting component 130 is located at the outside of backboard 110, equal light-emitting component 130 has been placed in opening environment, be located at the backlight module 100 of backboard 110 inside compares with light-emitting component 130, the Air Flow of backboard 110 outsides is more smooth and easy, and can improve the heat radiation power of backlight module 100.
the above, it is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet be not to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solution of the present invention content, any simple modification that foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
