Abstract
The utility model relates to LED-backlit module, and direct-light type LED backlight module lamp bar package assembly is provided.Be mainly used in improving lamp shadow backlight or the shadow phenomenon that direct-light type LED backlight module warps because reflecting paper is unsettled and causes, and reduce screw and the double faced adhesive tape of reinforcing reflecting paper.It comprises LED lamp, LED lens, circuit board, reflecting paper, and reflecting paper is provided with light hole, and light hole place is provided with lamp bar fixed structure, and lamp bar fixed structure adopts the setting of interval LED lens.Reflecting paper light hole mates with LED lamp and LED lens, and lamp bar fixed structure mates with light hole.The utility model is applicable to liquid crystal panel, lamp box, panel light.The utility model can effectively improve the bad optics tastes such as the lamp shadow, shadow of backlight module, and can also increase the light source reflection of backlight module, increases brightness, reduces screw assembling quantity, has dismounting easy, safe and reliable feature.
Description
Technical field
The utility model relates to LED-backlit module, particularly direct-light type LED backlight module lamp bar package assembly.
Background technology
Direct-light type LED backlight module generally adopts circuit board to fix LED lamp and lens as carrier at present, lens cover LED lamp, the assembling of reflecting paper covering board, the position of the corresponding lens of reflecting paper is provided with light hole, when backlight is luminous, reflecting paper, due to the thinner thickness phenomenon that easily warps, causes the phenomenon of LED lamp and lens surrounding lamp shadow and shadow, and optics taste and brightness decay are brought to very large impact.In reflecting paper light hole position, also need to use in addition more screw or double faced adhesive tape to reinforce reflecting paper, strengthen workload and the cost of production and assembly.
Utility model content
The technical problems to be solved in the utility model is lamp shadow and shadow phenomenon in prior art, and the screw of reflecting paper or additional workload and the cost that double faced adhesive tape brings are reinforced in more use.
For addressing the above problem, the utility model provides direct-light type LED backlight module lamp bar package assembly, comprises LED lamp bar, reflecting paper.Wherein LED lamp bar comprises LED lamp, lens, circuit board, and lens cover LED lamp; Reflecting paper is provided with light hole, and size and the lens of light hole match, and light hole place arranges lamp bar fixed structure.
Further, described lamp bar fixed structure is the reflecting paper that lamp bar is pushed down the bending of light hole place.
Further, described lamp bar fixed structure interval lens arrange, and the lens number at interval is more than or equal to 1.
The beneficial effects of the utility model are: lamp bar fixed structure makes reflecting paper be close to lamp bar, eliminated reflecting paper unsettled warp cause the bad optics tastes such as lamp shadow, shadow, and can also increase the light source reflection of backlight module, increase brightness; Because reflecting paper is close to lamp bar, light hole place does not just need screwing or double faced adhesive tape again, therefore can reduce screw or double faced adhesive tape quantity, has dismounting easy, safe and reliable feature.

Fig. 4 is the schematic rear view that the utility model is implemented structure.
In figure, number: 101 is lens, and 102 is reflecting paper, and 103 is circuit board, and 104 is LED lamp, and 201 is light hole, and 202 is lamp bar fixed structure
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
A backlight module forms by organizing lamp bar more, and lamp bar comprises LED lamp, lens, circuit board.Reflecting paper is to cover on many group lamp bars to cover circuit board and expose lens, thereby reaches lens component bright dipping, the catoptrical object of reflecting paper.
As shown in Figure 1, lens 101 cover LED lamp 104 to the utility model assembling schematic diagram, and lens 101 and LED lamp 104 are fixed on circuit board 103, and reflecting paper 102 covers on circuit board 103, and circuit board 103 is pushed down reflecting paper 102.
Fig. 2 is traditional direct-light type LED backlight module lamp bar package assembly schematic diagram, reflecting paper 102 is provided with light hole 201 at lens 101 places, during reflecting paper 102 covering boards (not marking in figure), because reflecting paper 102 is thinner, easy unsettled the warping of light hole 201 edge parts, the unsettled place warping can affect lens 101 bright dippings, inhomogeneous with also allowing reflecting paper 102 reflect, and causes LED lamp and lens 101 surrounding lamp shadow and shadows.
In embodiment Fig. 3, in order to eliminate, light hole edge is unsettled to warp, and lamp bar fixed structure 202 is set at light hole place 201.Particularly, when setting out unthreaded hole 201 in reflecting paper 102, do a sweep simultaneously.When assembling is implemented, lamp bar is pushed down the reflecting paper 102 of sweep.The size of light hole 201 is mated with lens 101, and the geomery of lamp bar fixed structure 202 mates with light hole 201.Lamp bar fixed structure 202 adopts interval lens 101 to arrange.Lamp bar fixed structure 202 itself has reinforcement effect, is therefore having lamp bar fixed structure 202 places, can re-use for reinforcing screw and the double faced adhesive tape of reflecting paper 102.
Fig. 4 is the back view that utility model is implemented structure, in Fig. 4, in conjunction with Fig. 3, can understand more intuitively lamp bar fixed structure 202.
In conjunction with the embodiments, lamp bar fixed structure 202 makes reflecting paper 102 be close to circuit board, not only can this position lamp shadow of fine elimination and the phenomenon of shadow, and near the lamp shadow of position and shadow are also significantly improved, therefore in actual enforcement, can according to circumstances adopt interval to arrange, can adopt 3 the lens settings in the lens setting of 2, interval or interval, or more.Therefore the quantity of light hole 201 must setting corresponding to lens 101, but lamp bar fixed structure 202 can adopt space-number to be greater than or equal to 1 setting.
