Abstract
The utility model relates to a luminous computer keyboard membrane, comprising a keyboard membrane surface layer and a keyboard membrane lining combined with the keyboard membrane surface layer, between which a light-emitting circuit is arranged; the light-emitting circuit is formed by a plurality of LED lamp branches in parallel connection; LED lamps of each branch are in series connection; the light-emitting circuit is in connection with a power supply through a power supply joint. Wherein, the light-emitting circuit can be in series or parallel connection with a slide rheostat in order to adjust LED lamp brightness. The luminous computer keyboard membrane overcomes the disadvantage that a common keyboard membrane is inconvenient to use without lighting, can adjust brightness of a keyboard membrane in dependence on needs and directly use a computer to supply power and is safe and convenient to use.
Description
Technical field
The utility model belongs to a kind of keyboard membrane, specifically, relates to a kind of luminous computor-keyboard film.
Background technology
It is comparatively convenient that present computor-keyboard both domestic and external operates, and be suitable for using daytime, but under the situation that does not have illumination, the use meeting of keyboard do not put to no little inconvenience owing to seeing.
The utility model content
At the deficiencies in the prior art, the utility model provides a kind of computor-keyboard film that can be luminous.
Luminous computor-keyboard film described in the utility model, comprise the keyboard membrane top layer and with the compound keyboard membrane nexine in keyboard membrane top layer, be provided with illuminating circuit between keyboard membrane top layer and the keyboard membrane nexine, illuminating circuit forms by a plurality of LED lamp branch roads are in parallel, be connected in series between the LED lamp on each branch road, illuminating circuit connects power supply by power connection.
Wherein:
Described LED lamp branch road is 5.
The LED lamp is at least 1 on each described branch road.
Further, insert slide rheostat on total branch road of illuminating circuit, slide rheostat and LED lamp branch road are connected in series.By regulating the resistance sizes that slide rheostat inserts, can control the electric current of illuminating circuit, and then regulate the brightness of LED lamp on each parallel branch.
Again further, illuminating circuit inserts slide rheostat, and slide rheostat and every group of LED lamp branch road are connected in parallel.By regulating the resistance sizes that slide rheostat inserts on the parallel branch, and then the voltage at parallel branch two ends controlled, because the resistance of LED lamp is fixed, the electric current that passes through on every branch road can change along with the variation of voltage, thereby reaches the purpose of regulating the brightness of LED lamp.When the resistance of slide rheostat access was 0, the both end voltage of parallel circuits was 0, and the LED lamp on the parallel branch is not luminous at this moment; When the resistance of slide rheostat access was maximum, the both end voltage of parallel circuits was maximum, at this moment the LED lamp brightness maximum on the parallel branch.
Again further, power connection can be arranged to USB interface, can directly be connected with computer, and is efficient and convenient.
In addition, can add fluorescent material on keyboard membrane of the present utility model top layer, under dark state, can send fluorescence, play the effect of illumination, under the enough situation of fluorescence, can not need keyboard membrane is connected power supply.
The utility model has the following advantages with respect to prior art:
1, overcome the shortcoming that the common keyboard film is inconvenient to use under condition is understood in without a licence, this keyboard membrane can be luminous, by day all convenient uses in evening.
2, adjustable brightness is convenient for people to regulate keyboard membrane brightness according to environment of living in and demands of individuals.
3, be provided with USB interface, the operator can directly be inserted in it on computer, and is convenient and swift.
4, adopt fluorescence and the luminous two kinds of patterns of LED lamp, can select to use whether plug-in as required, when providing convenience, energy-conservation to greatest extent.
5, this product demand is wide, and cost is lower, is applicable to batch process.

Fig. 2 is another kind of illuminating circuit figure of the present utility model;
Fig. 3 is another illuminating circuit figure of the present utility model;
Fig. 4 is another illuminating circuit figure of the present utility model.
Among the figure: 1, LED lamp; 2, switch; 3, power supply; 4, slide rheostat.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of luminous computor-keyboard film, comprise the keyboard membrane top layer and with the compound keyboard membrane nexine in keyboard membrane top layer, be provided with illuminating circuit between keyboard membrane top layer and the keyboard membrane nexine, illuminating circuit forms by 5 LED lamp branch roads are in parallel, every group of LED lamp 1 is 1, and illuminating circuit connects power supply 3 by power connection.
As shown in Figure 2, a kind of luminous computor-keyboard film, comprise the keyboard membrane top layer and with the compound keyboard membrane nexine in keyboard membrane top layer, be provided with illuminating circuit between keyboard membrane top layer and the keyboard membrane nexine, illuminating circuit forms by 5 LED lamp branch roads are in parallel, LED lamp 1 is 1 on each branch road, and illuminating circuit connects power supply 3 by power connection.Wherein, insert slide rheostat 4 on total branch road of illuminating circuit, slide rheostat 4 is connected in series with LED lamp 1.
During use, regulate the resistance sizes that slide rheostat 4 inserts, can control the electric current of illuminating circuit, and then regulate the brightness of LED lamp 1 on each parallel branch.
As shown in Figure 3, a kind of luminous computor-keyboard film, comprise the keyboard membrane top layer and with the compound keyboard membrane nexine in keyboard membrane top layer, be provided with illuminating circuit between keyboard membrane top layer and the keyboard membrane nexine, illuminating circuit forms by 5 LED lamp branch roads are in parallel, LED lamp 1 is 1 on each branch road, and illuminating circuit connects computer by USB interface.Wherein, illuminating circuit inserts slide rheostat 4, and slide rheostat 4 is connected in parallel with LED lamp 1.
During use, regulate the resistance sizes that slide rheostat 4 inserts on the parallel branch, and then the voltage at parallel branch two ends is controlled, because the resistance of LED lamp 1 is fixed, the electric current that passes through on every branch road can change along with the variation of voltage, thereby regulates 1 brightness of LED lamp.When the resistance of slide rheostat 4 accesses was 0, the both end voltage of parallel circuits was 0, and the LED lamp 1 on the parallel branch is not luminous at this moment; When the resistance of slide rheostat 4 accesses was maximum, the both end voltage of parallel circuits was maximum, at this moment the LED lamp 1 brightness maximum on the parallel branch.
As shown in Figure 4, a kind of luminous computor-keyboard film, comprise the keyboard membrane top layer and with the compound keyboard membrane nexine in keyboard membrane top layer, be provided with illuminating circuit between keyboard membrane top layer and the keyboard membrane nexine, illuminating circuit forms by 5 LED lamp 1 branch roads are in parallel, have 2 LED lamps to be connected in series on each branch road, illuminating circuit connects computer by USB interface.
