The present invention protrudes out backboard by making the teat of light guide plate, and makes light-emitting component arrange along teat, makes light-emitting component in backlight module of the present invention be located at the outside of backboard, and reduces the impact by light conducting board from deformation.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to technological means of the present invention can be better understood, and can be implemented according to the content of instructions, and can become apparent to allow above and other object of the present invention, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Figure 1 shows that the perspective exploded view of backlight module of the present invention.
Fig. 2 is the schematic diagram of light guide plate and light-emitting component in Fig. 1.
Figure 3 shows that the enlarged diagram of Fig. 2 centre circle III.
Embodiment
For further setting forth the present invention for the technological means reaching predetermined goal of the invention and take and effect, 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 side-light backlight module, and it comprises backboard 110, light guide plate 120, light-emitting component 130 and reflection bar 140.
Wherein, backboard 110 is a rectangular box, is provided with the receiving space 111 of collecting light guide plate 120 and reflection bar 140 in the middle part of it.Light guide plate 120 and reflection bar 140 are located in the receiving space 111 of backboard 110, and reflection bar 140 is located between four sides of light guide plate 120 and backboard 110.Light-emitting component 130 is located at light guide plate 120 side, and is positioned at the outside of backboard 110.
See also Fig. 2 and Fig. 3, the light guide plate 120 in the present invention is a male type light guide plate 120.This light guide plate 120 has one and to be stretched out the teat 121 formed by the side perpendicular with exiting surface of light guide plate 120.This teat 121 can match with the base of televisor or lamp box, as the backlight showing LOGO, or only as appearance member.The corresponding teat 121 of backboard 110 is provided with opening 112, and teat 121 protrudes out backboard 110 by this opening 112.
Specifically, the teat 121 of light guide plate 120 is roughly that " (" shape, it comprises the one first limit 121a paralleled with the side arranging teat 121 of light guide plate 120 and two the Second Edge 121b tilted arranging the side of teat 121 being connected the first limit 121a and light guide plate 120.Above embodiment only lists wherein a kind of shape of teat 121, and understandable, the shape of teat 121 is not limited thereto.Light-emitting component 130 in the present invention comprises some light emitting diodes, and these light emitting diodes arrange along one of them side of teat 121.That is, light-emitting component 130 at least one of them arrangement in the first limit 121a and Second Edge 121b of teat 121.The arrangement mode of light-emitting component 130 can be evenly distributed, also can be uneven arrangement.Interval between adjacent light emitting element 130 can adjust according to the arrangement mode of the quantity of light-emitting component 130, light-emitting component 130 and the spread length on teat 121.
In the present invention, reflection bar 140 comprises the some reflection bars being located at light guide plate 120 4 sides, 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 emphasis reflector space, and such as, the two ends of the side relative with teat 121 of light guide plate 120, white reflection bar 142 can be located at other region except emphasis reflector space.Certainly, reflection bar 140 of the present invention also only can comprise silver slurry reflection bar 141 or only comprise white reflection bar 142.
The present invention is by being arranged to the mode of male type light guide plate 120 by light guide plate 120, the teat 121 of light guide plate 120 is made to protrude out backboard 110, and make light-emitting component 130 arrange along teat 121, make light-emitting component 130 in backlight module 100 of the present invention be located at the outside of backboard 110, and reduce the impact of being out of shape by light guide plate 120.Secondly, backlight module 100 of the present invention and light-emitting component 130 are located at compared with the backlight module 100 of backboard 110 inside, light-emitting component 130 diminishes with the contact length of light guide plate 120, and reduce the length of the part light guide plate 120 that can expand, further reduce the impact that light-emitting component 130 is out of shape by light guide plate 120.Further, backlight module 100 of the present invention significantly can reduce the quantity of light-emitting component 130, effectively reduces light source cost.
Further, in backlight module 100 of the present invention, light-emitting component 130 is located at the outside of backboard 110, light-emitting component 130 is equaled to be placed in opening environment, compared with the backlight module 100 being located at backboard 110 inside with light-emitting component 130, the air flowing of backboard 110 outside 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, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, according to any simple modification that 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.
