Because the button of this kind illuminated keyboard has covered most light, has reduced the effective utilization of light source, has increased the power consumption of electronic product.Therefore, existing light guide plate still needs to be improved in design.
The utility model content
For overcoming the existing defective of above-mentioned illuminated keyboard, technical problem to be solved in the utility model is, a kind of illuminated keyboard is provided, and light concentrated transmitted and penetrate between the slit of keyboard, to improve the effective utilization of light source, reach the purpose of electronic product low power consumption.
In order to solve the problems of the technologies described above, the utility model provides a kind of illuminated keyboard, comprise button, be located at the cushion of button below and be located at the backlight arrangement of cushion below, there is the slit space between described each button, each slit is interconnected to form the annular slot around button, described backlight arrangement is made of light-emitting component, thin film circuit and light-leading film, and light-emitting component is located at the side of light-leading film, or embeds in light-leading film and the thin film circuit layer; Described thin film circuit is made of topmost thin film circuit and lower film circuit; Described light-leading film is located between topmost thin film circuit and the lower film circuit, and offers porose in the annular slot position of corresponding button.
With respect to prior art, the utility model illuminated keyboard, utilize perforate on the light-leading film and the position corresponding relation of annular slot, naturally the annular slot place around button forms the leaded light path, hole when having avoided the topmost thin film circuit as optical waveguide layer and the combination layout design of circuit, thus the fabric swatch design difficulty of thin film circuit reduced.Also utilize the hole of light-leading film and the corresponding relation of key position, photoconduction is caused the annular slot that is adjacent between the button, to reduce light scattering, improve the directivity that light penetrates, and then improve the use efficiency of light, thereby reach the low power consumption of electronic product.
As a kind of improvement of the utility model illuminated keyboard, topmost thin film circuit and lower film circuit are transparent material, and upper strata, lower film circuit are the transparent materials with different colours, to adapt to the keyboard Designing needs of colorful form.
As a kind of improvement of the utility model illuminated keyboard, light-leading film is side light-emitting type optical waveguide layer, to reduce light to the scattering of the non-output optical zone of end face, improves the directivity that light penetrates, and allowing light more penetrate in the concentrated area, thereby further improves the effective utilization to light.
As a kind of improvement of the utility model illuminated keyboard, the surface of light-leading film has additional out luminous point, in order to flexibly and fast realize the light path design backlight to the special shape button; Also can independently as secondary light source, to increase certain regional brightness, realize special backlight design effect.
A kind of improvement as the utility model illuminated keyboard, light-leading film is located between button and the cushion, or between cushion and the topmost thin film circuit, be beneficial to the fixing and assembling of light-leading film on elastic insert or topmost thin film circuit, and can avoid light-leading film thickness to the interference of the electrical contact conducting of upper and lower layer film circuit.
As a kind of improvement of the utility model illuminated keyboard, the surface of upper film circuit layer has additional reflector layer by coating method, to prevent that light scatters out from the topmost thin film circuit in the light-leading film.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model _ illuminated keyboard.
Embodiment
See also Fig. 1, the utility model illuminated keyboard, comprise button 10, be located at the cushion 20 of button below and be located at the backlight arrangement of cushion below, there is slit 11 space between each button, each slit is interconnected to form the annular slot around button, and the mutual interconnection of the annular slot of each button forms a chain of shape slit.
Wherein, backlight arrangement is made of light-emitting component 30, thin film circuit 40 and light-leading film 50, and light-emitting component 30 is located at the side of light-leading film 50, or embeds in 40 layers of light-leading film 50 and the thin film circuits.Thin film circuit 40 is made of topmost thin film circuit 41 and lower film circuit 43, and topmost thin film circuit 41 is provided with the first electrical contact 411, and lower film circuit 43 is provided with the second electrical contact 431 that matches with the first electrical contact.Light-leading film 50 is located between upper strata and the lower film circuit 41,43, light-leading film 50 offers porose 51 in the annular slot position of corresponding button, to utilize the position corresponding relation of hole 51 and annular slot, naturally the annular slot place around button forms the leaded light path, hole when having avoided topmost thin film circuit 41 as optical waveguide layer and the combination layout design of circuit, thus the fabric swatch design difficulty of thin film circuit reduced.Light-leading film 50 also can import and propagate the emitted light of light-emitting component, with the hole 51 that the utilizes light-leading film corresponding relation with button 10 positions, photoconduction is caused the annular slot that is adjacent between the button 10, to reduce light scattering, improve the directivity that light penetrates, and then improve the use efficiency of light, thereby reach the low power consumption of electronic product.And because upper strata and lower film circuit 41,43 make keyboard have better water proofing property without perforate.
Light-leading film 50 can be made by side light-emitting type optical material, is side light-emitting type optical waveguide layer, to reduce light to the scattering of the non-output optical zone of end face, improves the directivity that light penetrates, and allowing light more penetrate in the concentrated area, thereby further improves the effective utilization to light.
In other embodiments, light-leading film 50 also can be located between button 10 and the cushion 20, or between cushion 20 and the topmost thin film circuit 41, be beneficial to the fixing and assembling of light-leading film on elastic insert or topmost thin film circuit, and can avoid light-leading film thickness to the interference of the electrical contact conducting of upper and lower layer film circuit.
In the present embodiment, topmost thin film circuit 41 and lower film circuit 43 are transparent material.In other embodiments, upper strata, lower film circuit are also with the transparent material of different colours, to adapt to the keyboard Designing needs of colorful form.
In other embodiments, the surface of upper film circuit layer 41 can have additional reflector layer by coating method, to prevent that light scatters out from the topmost thin film circuit in the light-leading film.Coating process can be that direct blacking is processed, or prints first one deck white medium at non-output optical zone, and seal is black again reduces light scattering to hide light leak, improves the directivity that light penetrates, thereby further improves the effective utilization to light.
The according to the above description announcement of book and instruction, the utility model those skilled in the art can also change and revise above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not consist of any restriction to the utility model just for convenience of description.
