Specific embodiment
The application is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining related invention, rather than the restriction to the invention.It also should be noted that in order to
Convenient for description, part relevant to invention is illustrated only in attached drawing.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Fig. 1 and Fig. 2 are please referred to, the present embodiment provides a kind of backlight module, including backboard 1, is equipped on the inside of the backboard 1
Reflector plate 2, the reflector plate 2 are equipped with multiple grooves 9, and the groove 9 is arranged through the reflector plate 2, each groove 9
It is inside placed with lamp bar 3,2 top of reflector plate has also been sequentially arranged diffuser plate 4 and diaphragm 5.
Backlight module in the present embodiment installs sheet emitting on the inside of backboard first, and groove is then opened up on reflector plate,
Lamp bar is placed in groove, lamp bar is positioned by reflector plate, does not need to position lamp bar by backboard, is simplified
The structure of backboard, so that, without being modified to back board structure, eliminating backboard mold when corresponding multiple lamp bar schemes
Change because backboard mold alteration cost is high, be greatly saved backboard mold change expense, upgrade lamp bar scheme
Shi Jieyue time.
Further, 9 length of groove is not less than 3 length of lamp bar, and 9 width of groove is not less than the lamp bar
3 width.
Lamp bar is placed in the groove that reflector plate opens up in the present embodiment, lamp bar is positioned by reflector plate,
The size slightly larger than lamp bar that the middle size by groove is arranged assembles enhanced convenience so that lamp bar is readily placed in groove；
The big 1mm of length for the ratio lamp bar that wherein preferably the length of groove is arranged, the width for the ratio lamp bar that the width of groove is arranged
The setting of big 0.5mm, above-mentioned size can not only be convenient for the assembling of lamp bar, and will not generate biggish error.
Further, multiple positioning convex points 6 are equipped on the inside of the backboard 1, the reflector plate 2 is equipped with and the convex
The location hole 7 of 6 cooperation of point.
Carry out the installation of reflector plate in the present embodiment first on the inside of backboard, reflector plate and backboard are determined by four sides
Position also sets up multiple positioning convex points to guarantee the accuracy of sheet emitting positioning on the inside of backboard, corresponding to set on reflector plate
The location hole matched is set, is cooperated by the location hole on the positioning convex point and reflector plate on backboard, reflector plate is carried out
Accurate positioning, guarantees the installation effect of sheet emitting；Meanwhile it being illustrated in figure 3 back board structure schematic diagram, positioning convex point setting exists
The inside of backboard, backboard outside is without structures such as any exposed aperture or other salient points, so that more clean and tidy on the outside of backboard
And beauty.It is positioned in addition, sheet emitting and backboard pass through four sides first, therefore, the convex points on the inside of backboard is set
Amount is without too many, at least two positioning convex points of setting, has been preferable to provide four positioning convex points in Fig. 3 and has been positioned, more
Further, the number of the positioning convex point and the size of entire backboard are not related, and the variation of backboard size does not interfere with fixed
The locating effect of position salient point, so that the structure of backboard is more succinct.
Further, 7 size of location hole is not less than 6 size of positioning convex point.
The size slightly larger than positioning convex point that location hole is arranged in the present embodiment, also for the peace for facilitating reflector plate
Dress is preferably greater than positioning convex point 0.5mm for what the diameter of location hole was arranged, convenient for that will not generate biggish mistake while assembling
Difference.
Further, 3 surface of lamp bar is coated with white ink.
Lamp bar is fixed by reflector plate in the present embodiment, lamp bar is mounted in the groove on reflector plate, therefore
It needs for the color of lamp bar and reflector plate to be arranged consistent, guarantees the reflecting effect of reflector plate, wherein spraying on lamp bar surface white
Color ink guarantees the reflecting effect of reflector plate whole surface using the white ink of pure white high reflection.
Further, multiple LED light 8 are evenly arranged in the lamp bar 3.
Fig. 4 is lamp bar structural schematic diagram, multiple LED light is uniformly arranged in the lamp bar in the present embodiment, wherein not needing
Any through-hole for positioning or fixing or salient point etc. are opened up in lamp bar, so that the structure of lamp bar is more succinct.
Further, the reflector plate 2 is adhesively fixed with the backboard 1.
Fig. 5 be reflector plate structure schematic diagram, reflector plate is Nian Jie with backboard, offered on reflector plate placement lamp bar groove with
The location hole positioned with backboard, wherein pacifying in reflector plate close to the side glue spraying water of backboard for reflector plate is fixed
The positioning for carrying out reflector plate when dress by positioning convex point and location hole, is fixed reflector plate by the glue of spraying,
It is easy to operate.
Further, silica gel is equipped between the backboard 1 and the lamp bar 3.
Silica gel is also set on the inside of backboard in the present embodiment, lamp bar is fixed by the silica gel, therefore silica gel is arranged
In position corresponding with reflector plate upper groove, the determination that when installation sets the enterprising line position of groove that lamp bar is placed on sheet emitting, into
One step is fixed by silica gel.
