Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
As shown in Figure 1, 2, 3, the preferred embodiment of the illuminating module of the utility model keyboard, be applicable to be arranged on a keyboard body (not shown) below with multiple buttons, and be applicable to be electrically connected a control circuit (not shown) that is installed on this keyboard body, to constitute a keyboard.
This illuminating module comprises light guide plate 5, one that luminescence unit 4 that a reflecting plate 3, one be fixed on these reflecting plate 3 end faces, one be stacked and placed on these reflecting plate 3 end faces and be close to this luminescence unit 4 and covers these luminescence unit 4 ground and cover the shadow shield 6 that is covered in these light guide plate 5 end faces, and electrical connection is installed on the switching circuit board 7 of this luminescence unit 4.In the present embodiment, this reflecting plate 3, this light guide plate 5 and these shadow shield 6 peripheries are via high temperature hot melt together with cementing in up and down, but while enforcement, this reflecting plate 3, this light guide plate 5, also can be adhesively fixed by other object of adhering not as limit with the fixed form of splicing up and down of this shadow shield 6.
This reflecting plate 3 is to be made up of lighttight flexible plastic material, has one upward towards this light guide plate 4 and the white light reflection surface 31 of reflection ray up.
This luminescence unit 4 comprises the LED42 and the other electron component (not shown) that are fixed on the conducting wire 41 of this light reflection surface 31, multiple electrical connections respectively and adhere to this conducting wire 41 with conducting polymer composite printing coating, and electrical connection is fixed on this conducting wire 41 and is exposed to the first terminal 43 of these reflecting plate 3 sides.This conducting wire 41 is made up of many fine wire (not shown), can be used for connecting the signal of driving LED 42, and can be elargol for forming the conducting polymer composite of this conducting wire 41, or other mixes the conducting resinl that has conductive metallic material and tool viscosity.LED42 is side-light type LED, has respectively a side exiting surface 420 emitting beam for level.In the present embodiment, this first terminal 43 is that consubstantiality is connected in this reflecting plate 3 sides, form flat flexible curved, and surface be laid with the circuit 431 being electrically connected with this conducting wire 41, can connect input for the luminous control signal of driving LED 42.
This light guide plate 5 is to accept that light ground that described LED42 produces is stacked is fixed on this light reflection surface 31 and next-door neighbour LED42, and there is this side exiting surface 420 towards LED42 meet light side 50, this light guide plate 5 is to be made up of the optical material of light-permeable, can meet light side 50 and accept the light that LED42 sends by this, make light enter its inside, and along its bearing of trend directing light, and can make light up with down appear.Owing to manufacturing the optical material numerous types of this light guide plate 5 and being prior art, therefore no longer describe in detail.
This shadow shield 6 is that these luminescence unit 4 ground of overlay masking are stacked and placed on this light guide plate 5 and these luminescence unit 4 tops, and has the fenestra 60 that multiple light running through up and down and can make this light guide plate 5 guide up passes.This shadow shield 6 has one towards this light guide plate 5 and can down reflect the white reflecting lamina 61 from the light of this light guide plate 5, and coating is fixed on these reflecting lamina 61 end faces and can be prevented the light shield layer body 62 of the black that light up penetrates.Fenestra 60 is to run through up and down this reflecting lamina 61 and this light shield layer body 62, and the distribution design of fenestra 60 is corresponding with the arrangement position of the button of this keyboard body, is that correspondence is positioned at button below respectively.
This switching circuit board 7 comprises that one is installed on the flexible circuit board body 71 of this control circuit with the deflection of transmitting control signal for being electrically connected, and an electrical connection is fixed on this flexible circuit board body 71 and can be separated and is electrically connected the second terminal 72 that is installed on this first terminal 43.
In the present embodiment, this the first terminal 43 is to adopt the structural shape that laminating is electrically connected up and down with this second terminal 72, but while enforcement, the first terminal 43 and the second terminal 72 also can make the male and female terminal pattern of mutually pegging graft into, because terminal pattern is numerous, therefore while enforcement, when not being limited with the above-mentioned type.
When the illuminating module of the utility model keyboard is used, can be after this reflecting plate 3, this luminescence unit 4, this light guide plate 5 and this shadow shield 6 all splice and have assembled, the control circuit setting position of the keyboard body using according to predetermined collocation in addition again, select this switching circuit board 7 of suitable profile and length to install, and while installation, only this second terminal 72 directly need be electrically connected on to outer this first terminal 43 outside this reflecting plate 3 that is exposed at, do not need to destroy again the connected structure of reflecting plate 3, light guide plate 5 and shadow shield 6, quite convenient.
When use, the light that the LED42 of this luminescence unit 4 produces, can meet light side 50 and enter this light guide plate 5 inside via this, and be uniformly distributed along these light guide plate 5 bearing of trends, and up with down appear.Because the light reflection surface 31 of the reflecting plate 3 that is positioned at these light guide plate 5 belows is understood up reflection ray, and this reflecting lamina 61 that is stacked and placed on this shadow shield 6 of these light guide plate 5 tops is understood down reflection ray, and light cannot up penetrate this light shield layer body 62, so this light guide plate 5 up can be reflected back this light guide plate 5 by this reflecting plate 3 with this shadow shield 6 respectively with the light down appearing certainly, light is uniformly distributed in this light guide plate 5, and the light that this light guide plate 5 is guided can only appear from the fenestra of this shadow shield 6 60, cause the button of top keyboard body luminous around.
In sum, arrange in addition one by this luminescence unit 4 and be electrically connected and be exposed at the structural design of the first terminal 43 of these reflecting plate 3 sides outward with this conducting wire 41, can be convenient to this reflecting plate 3, this luminescence unit 4, after this light guide plate 5 has connect with whole group of this shadow shield 6, the control circuit setting position of the keyboard body using according to collocation in addition again, select the switching circuit board 7 of suitable length and profile, and only the second terminal 72 of this switching circuit board 7 directly need be engaged in to the outer the first terminal 43 outside reflecting plate 3 that is exposed at, do not need to destroy again and engaged this fixing reflecting plate 3, the connecting structure of this light guide plate 5 and this shadow shield 6, can significantly improve the property easy to assembly between this switching circuit board 7 and this luminescence unit 4, and convenient according to the control circuit design of the keyboard body of collocation assembling, the flexible circuit board body 71 of the different contour structures of choice for use, can simplify illuminating module processing procedure and improve output and qualification rate.In addition, by the directly down design of 6 of this shadow shields of reflection ray of folded these reflecting plate 3 participants that are against reflection ray up of this light guide plate 5, can make the light that luminescence unit 4 produces be distributed in more uniformly in this light guide plate 5, and make the light luminance that appears from fenestra 60 more even, therefore, the illuminating module of this keyboard is a kind of illuminating module design of the innovation for keyboard, really can reach the purpose of this utility model.
