Abstract
The utility model relates to a key and a keyboard, and aims at providing a key. The key is provided with a key cap, the key cap is provided with a light-transmitting area, and the light-transmitting area includes a fluorescence portion. A light source module comprises at least an ultraviolet light source, and the ultraviolet light source is arranged under the key cap and transmits ultraviolet light incident to the fluorescence portion of the key cap.
Description
[technical field]
The utility model is relevant a kind of button and keyboard, be meant especially a kind of with the fluorescence portion of UV-irradiation button transparent area luminous button and keyboard.
[background technology]
Progress along with science and technology, various electronic product constantly comes out, for example be mobile computer (NoteBook), personal digital assistant (Personal digital assistants, PDA), mobile phone or super brain machine (Ultra Mobile Personal Computer, UMPC) etc.These electronic products all need to see through keyboard input characters or numeral, with editing data or call.
General keyboard comprises several buttons, and each button has printed the literal or the numeral of representative.Yet the user is under dim environment, and the literal on but can't the identification button, and can't use keyboard has caused to use and gone up inconvenience greatly.Therefore, how to research and develop a kind of Keysheet module, in dim environment, debate the knowledge literal, for researching and developing one of important directions at present to make things convenient for the user.
Yet general employed structure is to be light source with visible light emitting diode (LED), with the diffusion point of irradiation light guide plate, and because general visible light emitting diode is the strength of light at 0～120 degree, causes the clear zone problem of light inlet easily.
Moreover the light guide plate edge can be because of the end of total reflection, cause producing the light leak problem around the light guide plate, and the refraction of visible light between can be therefore and collocation produces the problem of colour cast.
In addition, because the printing ink of fluorescence indication after in the application being first irradiating ultraviolet light, absorption ultraviolet light energy, in the dark can sending energy and reach luminous, but less because of stored energy capacitance, therefore the luminous time just is restricted, and can't reach the luminous of continuation.
In view of this, this case utility model people satisfies to be engaged in for many years with it and makes and the design practical experience, and the active research improvement, and makes and test through sample repeatedly, and then specifically improves the shortcoming of above-mentioned known keyboard, causes eventually and finishes the utility model.
[utility model content]
A purpose of the present utility model provides a kind of button, and this button is provided with a keycap, and this keycap has a transparent area, and this transparent area comprises a fluorescence portion; Light source module comprises at least one ultraviolet source, and this at least one ultraviolet source is arranged on the below of this keycap, and the emission ultraviolet light is incident to the fluorescence portion of this keycap.
As optional technical scheme, this fluorescence portion has fluorescent ink layer, is arranged on this transparent area.As further alternative technical scheme, this fluorescent ink layer is that red fluorescence printing ink point, green fluorescence printing ink point and/or blue-fluorescence printing ink point constitute.
As optional technical scheme, layer mixes for the fluorescent material of this transparent area in this fluorescence portion.
As optional technical scheme, this ultraviolet source is made of ultraviolet light-emitting diodes.
As optional technical scheme, the fluorescence portion of this keycap has pattern or character layer.
As optional technical scheme, this ultraviolet light of this at least one ultraviolet source directly is incident to the fluorescence portion of this keycap.
As optional technical scheme, this light source module comprises light guide plate, and this ultraviolet light of this at least one ultraviolet source is incident to the fluorescence portion of this keycap indirectly by this light guide plate.
A purpose of the present utility model provides a kind of illuminated keyboard, and it comprises above-mentioned a kind of button at least.
Benefit of the present utility model is to avoid prior art the shortcoming in keyboard local bright excessively (clear zone) to occur, can also use for a long time.
[description of drawings]
Fig. 1 represents the structural representation of the keyboard of a kind of embodiment of the utility model.
Fig. 2 represents the structural representation of the button of a kind of embodiment of the utility model.
Fig. 3 represents the press-key structure schematic diagram of another embodiment of the utility model.
[embodiment]
Please also refer to Fig. 1 to Fig. 2, wherein, Fig. 1 represents the structural representation of the keyboard of a kind of embodiment of the utility model, and Fig. 2 represents the structural representation of the button of a kind of embodiment of the utility model.
The keyboard 1 of present embodiment has the light source module 3 of a plurality of buttons 2 and 2 settings of corresponding button, and present embodiment describes with one key 2.
And light source module 3 has a fluorescence portion 31 and at least one ultraviolet source 32, and fluorescence portion 31 is formed on the transparent area 22, and fluorescence portion 31 is a fluorescent ink layer, can be a plurality of red fluorescence printing ink points, green fluorescence printing ink point and/or blue-fluorescence printing ink point and constitutes.In other embodiments, fluorescence portion can be that the layer of fluorescent powder of transparent area 22 is mixed layer.And ultraviolet source 32 can be ultraviolet light-emitting diodes (LED), be arranged on keycap 2 belows, do not have opaque obstacle between ultraviolet source 32 and the transparent area 22, ultraviolet source 32 directly shines the fluorescence portion 31 that is arranged on the transparent area 22 with ultraviolet light, to reach luminous purpose; And human eye and can't see ultraviolet light, therefore can avoid producing problems such as clear zone, light leak and colour cast; Moreover because fluorescence portion 31 has a plurality of phosphor dots, so ultraviolet lighting is when being mapped to phosphor dot, sustainable carry out luminous.Corresponding transparent area 22 also has the pattern or the character layer of formation literal (character), indicator diagram, and this layer can be made separately, also can be served as by fluorescent ink layer.
Refer again to Fig. 3, the press-key structure schematic diagram of another embodiment of its expression the utility model.The keyboard 1 of present embodiment is compared light source module 3 and is had more light guide plate 33 and be arranged on button 2 belows with Fig. 2, and ultraviolet source 32 can be ultraviolet light-emitting diodes (LED), be arranged on light guide plate 33 one of them side, present embodiment describes to be arranged on light guide plate 33 both sides, ultraviolet source 32 is directly incident on light guide plate 33 with ultraviolet light, to shine the fluorescence portion 31 that is arranged on the transparent area 22 indirectly in ultraviolet ray through light guide plate 33 again, to reach luminous purpose; And human eye and can't see ultraviolet light, therefore can avoid producing problems such as clear zone, light leak and colour cast.
And because ultraviolet light is a single wavelength, long the transmission person of the long distance of side because of travel path, the variation of refractive index and wavelength can not take place, reach the effect of light stability.
The above embodiment's is illustrating of technical solutions of the utility model, is not in order to limit interest field of the present utility model.
