Embodiment
The illuminated keyboard of the utility model one first preferred embodiment below is described.See also Fig. 2 to Fig. 4, Fig. 2 shows first diagrammatic cross-section of the illuminated keyboard of the utility model one first preferred embodiment, Fig. 3 shows second diagrammatic cross-section of the illuminated keyboard of the utility model one first preferred embodiment, and Fig. 4 shows the perspective exploded view of button wiring board of the illuminated keyboard of the utility model one first preferred embodiment.
As Fig. 2 and shown in Figure 3, illuminated keyboard 2 comprises a plurality of buttons 21, button wiring board 22 and second reflecting plate 23.In addition, comprise that more light-emitting component 24 is arranged at button wiring board 22 sides and keycap guide support 25 is arranged at button wiring board 22 tops.
First reflecting plate 223 is arranged at down between wiring board 222 and the last wiring board 221, in order to intercept down wiring board 222 and last wiring board 221, make between a plurality of contact 2221a down and a plurality of upper contact 2211a and keep a distance, wherein, first reflecting plate 223 has a plurality of second perforates 2231 corresponding to a plurality of upper contact 2211a.
Main creation characteristic of the present utility model is to utilize first reflecting plate 223 to intercept following wiring board 222 and contacts with last wiring board 221 to avoid down wiring board 222 with last wiring board 221, and another feature then is to utilize down wiring board 222 to conduct the light beam that light-emitting components 24 provide.
Particularly, light-emitting component 24 is arranged at down the first side 222a of wiring board 222, in order to produce a light beam, in this example, light-emitting component 24 be light emitting diode (Light Emitting Diode, LED).
After light beam that light-emitting component 24 provides entered down wiring board 222, light beam can conduct in the wiring board 222 down.
Following wiring board 222 has low absorptivity and high index of refraction, optional self-polycarbonate (PC), polymethylmethacrylate (PMMA), polyethylene terephthalate (PET) or silicones transparent light guide materials such as (silicone), but not as limit.
In addition, a plurality of light guide structures 225 of the light beam that provides in order to gathering and scattering light-emitting component 24 are provided the lower surface of following wiring board 222, and a plurality of light guide structures 225 are set up according to the position of a plurality of buttons 21, when light beam runs into a plurality of light guide structure 225, a plurality of light guide structures 225 scattering that segment beam can be made progress, wherein, will be projected to a plurality of buttons 21 zones by the make progress segment beam of scattering of a plurality of light guide structures 225, so that a plurality of button 21 produces illumination effects.
What need supplementary notes is that the manufacturing technology of a plurality of light guide structures 225 can be divided into printing-type and non-printing-type two types.
The former utilizes the wire mark mode that light guide ink is imprinted on down the lower surface of wiring board 222 and forms different a plurality of light guide structures 225 shapes and distribution range.The latter is then with mode designing moulds such as chemical etching process or laser engraving technologies, then with ejection formation or technology such as hot-forming, makes a plurality of light guide structures 225 be formed at down the lower surface of wiring board 222.
Note that a plurality of light guide structures 225 usefulness for illustrating only among Fig. 2 and Fig. 3, is not shape, generation type and the distribution range in order to limit a plurality of light guide structure 225 of the present utility model.
Then, first reflecting plate 223 as shown in Figure 4 is arranged at down wiring board 222 tops, first reflecting plate 223 is made by light tight material and is had a high reflectance, therefore being able to auxiliary beam reflects downwards, scatter and disappear to avoid light beam upwards to penetrate down wiring board 222 backs, the light beam that light-emitting component 24 is provided can be improved to be utilized.
Can upwards be projected to a plurality of buttons 21 zones for making by the make progress segment beam of scattering of a plurality of light guide structures 225, first reflecting plate 223 has a plurality of first perforate 223a corresponding to a plurality of light guide structures 225.
In addition, in this example, be not limited to use first reflecting plate of being made by light tight material 223, also can use as Fig. 5 and first reflecting plate 26 shown in Figure 6.
Fig. 5 shows first schematic perspective view of first reflecting plate of the utility model one first preferred embodiment, and Fig. 6 shows second schematic perspective view of first reflecting plate of the utility model one first preferred embodiment.
First reflecting plate 26 comprises transparent substrates 261 and is formed at the lower surface (Fig. 5) of transparent substrates 261 or the reflectance ink 262 of upper surface (Fig. 6), makes first reflecting plate 26 be able to folded light beam.
Can upwards be projected to a plurality of buttons 21 zones for making by the make progress segment beam of scattering of a plurality of light guide structures 225, reflectance ink 262 is not formed on the transparent substrates 261 corresponding to a plurality of light guide structure 225(Fig. 2 and Fig. 3) part and form a plurality of transmission regions 264, so that upwards the segment beam of scattering is penetrated transparent substrates 261 and upwards is projected to a plurality of buttons 21 zones.
In addition, first reflecting plate 26 contacts with a plurality of contact 2221a down so that a plurality of upper contact 2211a stretches in being provided with a plurality of second perforates 263 corresponding to a plurality of thin film switch 224 parts.
Then go up wiring board 221 and be arranged at first reflecting plate, 223 tops, wherein go up wiring board 221 and make for light-transmitting materials, make that upwards the segment beam of scattering can be projected to a plurality of buttons 21 zones by last wiring board 221.
In addition, second reflecting plate 23(Fig. 2 and Fig. 3) be arranged at button wiring board 22 belows, wherein second reflecting plate 23 is made for light tight material and is had a high reflectance, be used for upwards reflection of auxiliary beam, scatter and disappear to avoid light beam to penetrate down wiring board 222 backs downwards, utilized so that the light beam that light-emitting component 24 provides can improve.
Next please continue with reference to Fig. 2 and Fig. 3, below go on to say a plurality of buttons 21 of the utility model one first preferred embodiment and the structure of keycap guide support 25.At first, each button 21 has keycap 211 and flexible member 212.In addition, keycap guide support 25 is arranged at button wiring board 22 tops, and keycap guide support 25 has a plurality of hollow-out parts 25a, and a plurality of keycaps 211 are fixed in a plurality of hollow-out parts 25a of keycap guide support 25 respectively, and can move up and down in a plurality of hollow-out parts 25a.
