Compared with prior art, button that the utility model provides and translucent construction thereof by the optical arrangement between condensing film and the light-emitting component, change the ejaculation direction of light, and can avoid light leak or paste problems such as offset.
For the above-mentioned of the utility model and other aspects are had better understanding, hereinafter is special lifts preferred embodiment, and cooperates appended graphicly, elaborates as follows:
Description of drawings
Fig. 1 illustrates according to the keyboard of the utility model one embodiment and the sketch map of button thereof.
Fig. 2 illustrates the button that has transparent area among Fig. 1 and the generalized section of translucent construction thereof.
Embodiment
The button of present embodiment and translucent construction thereof are by the optical arrangement between condensing film and the light-emitting component, change the ejaculation direction of light, form collimated light beam after making light that light-emitting component penetrates towards keycap via the condensing film deviation.But the transparent area of collimated light beam vertical incidence keycap is to reduce the situation of light leak.
Below propose an embodiment and be elaborated, embodiment in order to as the example explanation, is not the scope in order to the protection of limit the utility model desire only.
Please with reference to Fig. 1 and Fig. 2, Fig. 1 illustrates according to the keyboard of the utility model one embodiment and the sketch map of button thereof, and Fig. 2 illustrates the button that has transparent area among Fig. 1 and the generalized section of translucent construction thereof.Button 110 with keyboard 100 is an example, and button 110 comprises keycap 112, light-emitting component 114, condensing film 116, supporting bracket 118 and bracing frame 120.Keycap 112, light-emitting component 114 and condensing film 116 are formed translucent construction 111.Keycap 112 has transparent area 113.Light-emitting component 114 has exiting surface 115, and exiting surface 115 is corresponding to transparent area 113.Condensing film 116 is disposed at exiting surface 115 tops.Bracing frame 120 is the scissors leg structure for example, is movably connected between keycap 112 and supporting bracket 118, to support keycap 112 and to let the keycap 112 can be with respect to supporting bracket 118 displacement vertically.
In addition, button 110 more comprises polyester film 122 and adhesion layer 124.Polyester film 122 has opening 123, adhesion layer 124 be attached to opening 123 around and be engaged between condensing film 116 and the polyester film 122.In detail; In the present embodiment; Because condensing film 116 covers the top of the opening 123 and the light-emitting component 114 of polyester film 122; Light-emitting component 114 is arranged in opening 123, engages with adhesion layer 124 around the opening 123, so that light-emitting component 114 is coated in the area of space that condensing film 116 and polyester film 122 surrounded.Therefore, light-emitting component 114 all can pass condensing film 116 towards the light L that keycap 112 penetrates, and is difficult for taking place problems such as aberration or light is gloomy.
In addition, condensing film 116 for example is a light polarizing film, and it has the function that can adjust rising angle.Condensing film 116 is a multilayer film, and it can comprise protective layer and polarization matrix layer.The material of protective layer can be PETG (Polyethylene terephthalate, PET), the polarization matrix layer is to be made up of the polarisation material, its material can be acid polyethylene (Poly vinyl alcohol, PVA).The bent light rate of condensing film 116 can be between 30～40%.Above-mentioned material and polarized light property are merely for example, and the utility model is not as limit.
With horizontal polaroid is example, and the light L through condensing film 116 will form horizontal light beam after deviation, and in the transparent area 113 of vertical incidence to keycap 112, so light L can not cause light leak to outdiffusion.Therefore, present embodiment can condensing film 116 replaces the light shield of convention, to reduce light leak.In addition, on processing procedure, condensing film 116 also can directly be attached on the exiting surface 115 of light-emitting component 114, reduces the step of processing procedure and avoids pasting offset and produce problems such as aberration or light is gloomy.
In sum, though the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Has common knowledge the knowledgeable in the technical field under the utility model, in spirit that does not break away from the utility model and scope, when doing various changes and retouching.Therefore, the protection range of the utility model is as the criterion when looking the claim person of defining.
