Description

Light guidance wire type illuminating keyboard

Technical field

The utility model relates to illuminated keyboard, specifically, relates in the environment of unglazed or the low light level and has realized lighting function, especially has a kind of light guidance wire type illuminating keyboard of economic, practical characteristics.

Background technology

Existing keyboard does not generally possess lighting function, if the user is under the environment of unglazed or the low light level during operation keyboard, need be by other lighting source, and correspondingly cause inconvenience for user's use.Thereby, illuminated keyboard has appearred in market, and, with the luminous lighting function under its no luminous environment or the low light environment and decoration functions and be subjected to the generally approval and the favor in market, wherein, comprise that keycap scribbles fluorescent material by its surface and realizes the fluorescence keyboard of lighting function, realizes the cold light keyboard of lighting function and the LED illuminated keyboard etc. of directly realizing lighting functions by the some LED that are built in keyboard by the cold light film that places below the keycap and be affixed on substrate surface.

But also there are many weak points in existing illuminated keyboard, for example: although the fluorescence keyboard has certain luminous indication and illumination functions, but because light is faint in use, moreover, the fluorescent material of key cap surface loses due noctilucent function because of wearing and tearing easily, and therefore, this function exists useful life short, the deficiency that poor reliability, practicality are not strong; And the cold light film of cold light keyboard is that whole plate is luminous, and illumination effect is relatively more dull, the more important thing is that to have cost uneconomical; Although and the brightness of LED illuminated keyboard is higher, non-uniform light, assembly process is more loaded down with trivial details, and the price comparison costliness.Therefore, along with the continual renovation of the continuous progress of science and technology and product is regenerated, in view of existing illuminated keyboard can't satisfy people's real consumption and demand, thereby, be still waiting further to improve and innovation.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of light guidance wire type illuminating keyboard, under the environment of unglazed or the low light level, realize having the light deixis by lighting function, make the keyboard layout and the clear demonstration of character thereof of keyboard, handled easily and use have realized the characteristics of hommization.

Technical problem of the present utility model realizes by following technical scheme: construct a kind of light guidance wire type illuminating keyboard, the keyboard power that comprises keyboard body and connection thereof, this keyboard body comprises substrate and top some key position holes thereof, and the some keycaps corresponding with described key position hole, it is characterized in that, described keycap comprises local transparent or semitransparent part at least, and described substrate is provided with the optical fiber that its light can pass through this keycap at least, and in the keyboard body, be provided with the light source with the corresponding cooperation of described optical fiber, and described light source is connected with described keyboard power.

The local transparent or semitransparent part preferred characters stroke of described keycap is transparent or semitransparent, promptly sweep by radium-shine ink lay with character stroke on the keycap, and, character on the keycap can be multiple character combination, as with five-stroke etymon and phonetic alphabet organic assembling on keycap, Chinese brevity code and Japanese brevity code organic assembling be in the first-class character style of keycap.Certainly, keycap also can whole clearing or translucent.So-called substrate is the plate body that plurality of keys is relied on, between keycap and circuit film.Key position hole is the key body that can hold button to be passed through, and matches with key arrangement.The end face of optical fiber is relative with the radiation direction of light source, and in the range of exposures of corresponding light source light.
