Abstract
The utility model relates to a light emitting diode (LED) gradually-changing dimming device of a keyboard with a backlight, in particular to a combination at least comprising any two-color static light or a plurality of dimmable color-changing light. The device is integrated with decorativeness and interestingness. The LED gradually-changing dimming device is characterized in that the device at least comprises a colorful LED which is built in the keyboard and a dimming element which is arranged on the keyboard, and the dimming element is connected with the colorful LED. When the LED gradually-changing dimming device is used in practice, the colorful LED can be adjusted through the dimming element, and a plurality of colors of light, including static and even cyclically dynamic colorful light can be emitted from the keyboard. Thereby, the LED gradually-changing dimming device has the advantages that the gradual light emitting effect can be achieved, the added value of the product can be increased, the structure is novel and simple, the implementation can be conducted easily, the device can provide endless interests to people who finish stress work, and the people-oriented feature is fully reflected.
Description
Technical field
The utility model relates to the backlight keyboard, specifically, relates to the combination that comprises any double-colored static light or some adjustable variable color light at least, and the LED that integrates ornamental, interesting a kind of backlight keyboard is the limit light modulating device gradually.
Background technology
Keyboard on the existing market 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, so illuminated keyboard on market, occurred, and, by the difference of its light source type, roughly can be divided into fluorescence formula illuminated keyboard, cold light film illuminated keyboard, backlight illuminated keyboard etc., and with its under no luminous environment or low light environment the luminous lighting function and be subjected to the generally approval and the favor in market.But, no matter be the illuminated keyboard of which kind of version, its light source generally adopts monochromatic form, and people are in use, its lighting function some dullness that seems, and that decorative function also has is to be hoisted, for example, also there are many weak points in aspects such as its interest and market attractiveness, and generally speaking, value-added content of product content is still waiting to improve.Therefore, along with the continuous progress of science and technology and the continual renovation of product are regenerated, the supporting structure of light source of existing illuminated keyboard can't satisfy the high-grade consumption demand of modern, thereby, be still waiting further to improve and innovation.
Summary of the invention
The LED that the technical problems to be solved in the utility model is to provide a kind of backlight keyboard is the limit light modulating device gradually, make up by comprising double-colored light source at least and can changing light, realization has at least two kinds of static monochromatic light and some kinds of adjustable compound variable color light, have the ornamental and interesting of illuminated keyboard light source now to promote, thereby improve value-added content of product.
Technical problem of the present utility model realizes by following technical scheme: the LED that constructs a kind of backlight keyboard is the limit light modulating device gradually, it is characterized in that, comprise the seven color LED that are built in keyboard at least, and place the Light modulating device on the keyboard, and this Light modulating device is connected with described seven color LED.When concrete the use, by Light modulating device seven color LED are regulated, make keyboard send some coloured light, comprise colorful coloured light static, that circulate even.
Seven mentioned in the technical program color LED are not limited to idiom " seven-color LED ", that described seven color LED not only comprise is double-colored, three looks etc. can change, mobile seven-color LED capable of circulation, also comprise different monochromatic some single led combinations, realize multi-colour luminous function, simultaneously, its style structure comprises difform LED such as round lamp, square lamp, paster.
The LED of the backlight keyboard that provides according to the utility model is the limit light modulating device gradually, it is characterized in that, described Light modulating device comprises rheostat, comprising knob and slidingtype, and, in the specific implementation, preferred this knob rheostat, it can be arranged at the optional position of surface of keyboard, perhaps be arranged at the optional position of keyboard side.
Certainly, in concrete implementation process, described Light modulating device also can adopt voltage regulator, comprising voltage-regulation elements such as employing loop constructions; Perhaps adopt current regulator, wherein also comprise Current Regulation elements such as triode.
The LED that realizes backlight keyboard of the present utility model is the limit light modulating device gradually, has following advantage: make the backlight keyboard have more the attraction of interest and eyeball, illumination effect also has more stereovision, can also increase the added value content of backlight keyboard, have quiet, dynamic lightshow effect, decoration function is remarkable; And structure is novel, and is simple in structure, implements easily, increases unlimited temperament and interest can also for people after tense working.
Description of drawings
Fig. 1 is the embodiment partial structurtes decomposing schematic representation of the utility model backlight keyboard;
Fig. 2 A is the example structure schematic diagram that the utility model adopts the hollow out keycap;
Fig. 2 B is the example structure schematic diagram that the utility model adopts transparent or semitransparent keycap.
Embodiment
The LED of reference a kind of backlight keyboard as shown in Figure 1 is the limit light modulating device gradually, comprise the seven color LED2 that are built in keyboard 1 at least, and place the Light modulating device 3 on the keyboard 1, and this Light modulating device 3 is connected with seven color LED2.
With reference to shown in Fig. 2 A, keycap 8 can adopt hollow out character 80, and simultaneously, the keyboard shell of the remainder of keycap and following correspondence adopts opaque; With reference to shown in Fig. 2 B, keycap 8 can adopt transparent or translucent, and character 81 can directly adopt printing, and simultaneously, corresponding keyboard shell also all can adopt transparent or translucent below the keycap.In the specific implementation, as shown in Figure 1, preferred double-colored seven color LED2 especially adopt indigo plant/red dichromatism, acrylic light guide plate 5 places below the film 6, when concrete the use, with reference to as shown in Figure 1, the light that sends as seven color LED2 is by the screen print lattice-point of acrylic light guide plate 5, and generation reflection ray upwards, and reflection ray can pass through film 6 and top Capsule 7, passes to the external world by transparent or semitransparent keyboard shell and transparent or semitransparent keycap 8 again, realizes the lighting function of keyboard; Certainly, by the reflection ray of film 6 and Capsule 7, can be directly hollow out character 80 by keycap 8 pass to the external world.
In concrete use, if during the light look attitude that the user need select to be liked, can be by being arranged at the Light modulating device 3 on keyboard 1 surface, it is preferred knob rheostat, seven color LED2 are regulated,, make the utility model keyboard send some coloured light with reference to as shown in Figure 1, comprise colorful coloured light static, that circulate even, realize the dimming function and the decoration functions of backlight keyboard.
