Abstract
The utility model relates to a light source integrated light conducting board comprising a light conducting base plate whose lower surface is printed with light conducting ink spots, and a flexible PCB plate with LED light. The flexible PCB plate is connected with the light conducting base plate by a double sticky tape or adhesive, and the LED light is faced the light incidence surface of the light conducting base plate, then push-buttons are glued on the upper surface of the light conducting base plate by double sticky tape or adhesive, further a silica gel layer is glued on the lower surface of the light conducting base plate by double sticky tape or adhesive. The bottom surface of the silica gel layer is provided with a plurality of convex points. A plurality of striking flakes which are one-to-one corresponded with the convex points of the silica gel layer are glued on the lower surface of the silica gel layer by double sticky tape. The LED light is installed on the flexible PCB plate and then connected to the light conducting base plate, thereby the convenience of usage is improved, and the utility model is capable of being assembled with the push-buttons or the striking flakes to form a module. Using the light source integrated light conducting board, the thickness of the light conducting board is reduced to under 0.15mm, and the lighting is more even, more energy saving with less heat production.
Description
Technical field
The utility model relates to a kind of LGP, refers in particular to the one-piece type LGP of a kind of light source.
Background technology
Current, convenient for using mobile phone night, below button, assemble 8-22 grain sheet-shaped LED usually.This mode causes non-uniform light after light source shines button on the one hand, and colleague's power consumption is big, and easily heating influences consumer's use.In addition, the development along with mobile phone technique requires miniaturization, and the trend of ultra-thinization is obvious day by day, and traditional LED is because the restriction of thickness is difficult to adapt to the requirement of ultra-thinization.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of light source one-piece type LGP, it can effectively satisfy the development trend of miniaturization, ultra-thinization, and is easy to use.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the one-piece type LGP of a kind of light source, comprise that lower surface is printed with the light guide base plate of light guide ink point and has the flexible PCB plate of LED lamp, described flexible PCB plate links to each other with light guide base plate by two-sided tape or binder, and described LED lamp is over against the light incident end face of light guide base plate.
Further improvement in the technical proposal is that the upper surface of described light guide base plate is also by two-sided tape or the sticking button that is provided with of binder.
Further improvement in the technical proposal is, described light guide base plate lower surface is also by two-sided tape or binder is sticking is provided with layer of silica gel, and the bottom surface of layer of silica gel is provided with some salient points.
Further improvement in the technical proposal is that the lower surface of described layer of silica gel also is stained with some shell fragments that are provided with correspondingly with salient point layer of silica gel by two-sided tape.
Further improvement in the technical proposal is that described light guide base plate is PET sheet material or PC sheet material.
The beneficial effects of the utility model are: the utility model is connected with light guide base plate after being installed in the LED lamp above the flexible PCB plate again, improved the convenience that uses, simultaneously itself and button or shell fragment etc. can also be assembled into module for use, more convenient application.The one-piece type LGP of the utility model light source can drop to thickness below the 0.15mm, and is simultaneously luminous more even, more power saving, and heat has also reduced, and has promoted the development of LGP technology; LGP of the present utility model screen printing mode production has improved production efficiency, and can print 30 kinds of colors at least, has enriched color change.
Below in conjunction with accompanying drawing the utility model is described in further detail.

The specific embodiment
See also Fig. 1 and Fig. 2, the utility model provides a kind of light source one-piece type LGP, comprises that light guide base plate 2 and has the flexible PCB plate (FPCB) 5 of LED lamp 3.
Wherein, described light guide base plate 2 can adopt the base material of materials such as PET, PC, and is printed with the light guide ink point 1 that has the light diffusion property at light guide base plate 2 lower surfaces, and its mode of printing can adopt silk-screen.
Described flexible PCB plate 5 links to each other with light guide base plate 2 by two-sided tape 12 or binder, and flexible PCB plate 5 can link to each other with corresponding circuit by connector 4.Described LED lamp 3 is over against the light incident end face of light guide base plate 2, thereby the light that LED lamp 3 is sent is gone in the light guide base plate 2 from the end face direct projection of light guide base plate 2.
In addition, described light guide base plate 2 lower surfaces also glue by two-sided tape 6 or binder and are provided with layer of silica gel 7, and the bottom surface of layer of silica gel 7 is provided with some salient points.
As shown in Figure 3, also can be provided with button 9 and form a module by two-sided tape 8 or binder are sticking, so that use at the upper surface of described light guide base plate 2.
And as shown in Figure 4, the lower surface of described layer of silica gel 7 also is stained with some shell fragments 11 that are provided with correspondingly with salient point layer of silica gel 7 by two-sided tape 10, forms a module equally so that use.
The LGP that the printing ink that the utility model will have a light diffusion property is produced on PET or the PC sheet material 2 by the silk-screen technology print, and connect together the one-piece type LGP module that forms by adhesive tape 12 or binder with the flexible PCB plate 5 that has LED lamp 3, thickness is little, is convenient to use.
Claims (5)
1, the one-piece type LGP of a kind of light source, comprise that lower surface is printed with the light guide base plate of light guide ink point, it is characterized in that: the one-piece type LGP of described light source also comprises the flexible PCB plate that has the LED lamp, described flexible PCB plate links to each other with light guide base plate by two-sided tape or binder, and described LED lamp is over against the light incident end face of light guide base plate.
