Abstract
The utility model provides a USB typing speed indicator light. The indicator light is connected with a computer by a USB; a drive software controls the turning on and the turning off of an LED; the input value of the drive software is controlled by the knocking frequency of a keyboard; and the indicator light is also connected with a music player and is displayed by means of tempo, i.e. when the knocking velocity of the keyboard is accelerated, the lightness of the lamp changes to be higher, when the knocking speed of the keyboard is decelerated, the lightness of the lamp changes to be weaker, and when the selector switch of the LED lamp is set from 'procedure' to 'usual lightning', the indicator light is an LED desk lamp.
Description
Technical field:
The utility model relates to a kind of USB typing speed indication lamp, particularly relate to and a kind ofly connect computer by USB, by the light on and off of drive software control LED, the input value of drive software is by the FREQUENCY CONTROL of knocking of keyboard, and be connected with music player, show by rhythm.When the change-over switch of LED lamp is set to " Chang Liang " by " program ", be the LED tabletop lamp
Background technology:
Along with the constant growth of productivity, the continuous progress of science and technology, computer becomes office tools more and more commonly used, no matter is the student in Learning in School, and still the white collar in company's work all be unable to do without computer.The Chinese Consumers' Association's organizational strength has been done survey to the home PC market of Beijing, Shanghai, Tianjin, four municipalities directly under the Central Government in Chongqing.Investigation shows that the home computer popularity rate in 4 cities is 40.6%.Wherein buying family's quantity of computer over the past two years, is to buy more than two times of computer family summation before this.Still the family that does not have computer has 62.5% to plan to buy computer; The family of existing computer still has nearly 22% to want to buy new computer.Along with popularizing of computer is more and more general, the computer typewriter input also becomes a kind of technical ability of present people's indispensability, wants to make good use of computer and will learn well and how typewrite.Because in the use of computer, no matter be software application, or internet exchange, perhaps editing mail all needs the skilled input of typewriting of people.
How improving the typewrite efficient of input of people is a more and more valued problem, and the method for now general raising typewriting input is generally improved from hardware-software two aspects.Hardware aspect improves the keyboard layout reasonability by updating computor-keyboard, and the comfortableness of keyboard feel increases people's typing speed; Intelligent input method is constantly released in the software aspect, and various phrase libraries for temporary memory improve input efficiency.
And,, need in the dark surrounds of no lamp, still not have light can influence the identification of people for keyboard but can not influence others again if desired by the computer input at night.Therefore a kind of light among a small circle, indiffusible light source of providing must be arranged.LED light just in time has this advantage, and its light-ray condensing degree height be not easy diffusion, and brightness enough illuminates keyboard, makes people also can distinguish the character on the keyboard smoothly in the environment of dark, imports smoothly.
Mainly be as keyboard light in the present prior art from the LED of charged pool lamp.But the shortcoming of this LED lamp is to use for a long time, must in time change battery.The use of battery has not only increased the cost of lamp, and discarded battery has also caused pollution to environment, becomes irretrievable refuse.Its pollution that causes after discarded of battery may reach hundreds of square metres.Though some lamp also is connected with computer by USB, powers by computer, the function of this USB lamp also only is confined to provide illumination.
The utility model content:
In order to solve the problems of the technologies described above, the utility model provides a kind of USB typing speed indication lamp, connects computer by USB, light on and off by drive software control LED, the input value of drive software is by the FREQUENCY CONTROL of knocking of keyboard, and is connected with music player, shows by rhythm.When the change-over switch of LED lamp is set to " Chang Liang " by " program ", be the LED tabletop lamp.
Concrete utility model thes contents are as follows:
A kind of USB typing speed indication lamp, by LED light panel 1, USB connecting line 2 and USB interface 3 are formed, it is characterized in that: the LED light panel connects computer by USB, light on and off by drive software control LED, the brightness grow of lamp when the keyboard blow speed is fast, the brightness of lamp dies down when the keyboard blow speed is slow.
Described USB typing speed indication lamp is characterized in that: described LED light panel is square or rectangle.
Described USB typing speed indication lamp is characterized in that: the input value of described drive software is by the FREQUENCY CONTROL of knocking of keyboard, and is connected with music player, shows by rhythm.
Described USB typing speed indication lamp is characterized in that: described LED light panel is provided with change-over switch, can be set to " Chang Liang " by " program " control, as the LED tabletop lamp.
Described USB typing speed indication lamp is characterized in that: described USB connecting line is the common USB connecting line, the USB2.0 high-speed interface that described USB interface is used for the computer expert.The USB typing speed indication lamp can be connected with desktop computer or notebook with interface by connecting line.
Description of drawings
Fig. 1 is the schematic diagram of USB typing speed indication lamp described in the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described.
A kind of as shown in Figure 1 USB typing speed indication lamp, by LED light panel 1, USB connecting line 2 and USB interface 3 are formed, and it is characterized in that: the LED light panel connects computer by USB, by the light on and off of drive software control LED.And be connected with music player, show by rhythm.When typewriting take to certain frequency then the LED lamp stable light can be provided, and open music player, play easily soft music.And when the change-over switch of LED lamp is set to " Chang Liang " by " program ", be the LED tabletop lamp.The utility model adopts USB that the LED lamp is connected with computer, and the typewriting frequency that realizes keyboard by software is controlled the LED lamp, when people bring into use keyboard typing, the LED lamp is opened automatically, and need to keep certain typewriting frequency just can keep the steady illumination of LED lamp, the brightness grow of lamp when the keyboard blow speed is fast, the brightness of lamp dies down when the keyboard blow speed is slow.
So not only can also provide the method that detects the typing speed frequency to make people must be noted that typing speed and the frequency of oneself, improve constantly the typing skill of oneself so that people obtain enough light in the dark.And software has connected music player, can open player automatically when people typewrite input, plays melodious music, improves the comfort of people's typewriting.The LED lamp also is provided with switch, by switching to " Chang Liang " option, can be that the LED lamp remains brightness, is exactly a tabletop lamp that continues to provide illumination like this.
