Abstract
The utility model discloses a light emitting device of a keyboard, which mainly comprises a keyboard main body (1), keys (2) which are arranged on the keyboard main body (1) and a circuit board which is arranged in the keyboard main body (1). A light emitting diode (3) which is connected with the circuit board is arranged on the inner wall of each key (2). The keys (2) are made of high-transparency polymethylmethacrylate. By using the device, the light emitting diodes (3) can emit light to illuminate the keyboard in the dark. Moreover, since the light emitting diodes (3) have the characteristic of low power consumption, the light emitting device is energy-saving.
Description
Technical field
The utility model relates to computor-keyboard, specifically is a kind of light-emitting device of keyboard.
Background technology
Society all is provided with keyboard on many electron devices such as mobile phone, computer now, and therefore, when using keyboard, at every turn whether button can both be imported the quality and the efficient of the work that directly has influence on, study accurately.Yet a lot of now people were not subjected to the training of specialty, and keyboard is unfamiliar with, and need contrast keyboard input when the typewriting input.When light was dark, keyboard was fuzzy, is difficult for finding corresponding key, and this has just caused the error rate for input increase, thereby caused input efficiency to reduce.By additional light-emitting device keyboard is thrown light on, can address the above problem, still, not only power consumption is big to adopt this mode, also will be subjected to the restriction of occasion.Therefore, light-emitting device how to make a kind of low energy consumption and convenient use on keyboard becomes present social question of common concern, yet, also there is not corresponding apparatus now, do not see relevant report yet.
The utility model content
The purpose of this utility model is to overcome the problem that now keyboard does not have light-emitting device, and low-power consumption is provided, and the light-emitting device of a kind of keyboard easy to use.
The utility model mainly is achieved through the following technical solutions:
A kind of light-emitting device of keyboard mainly is made up of keyboard body, the circuit board that is arranged on the button of keyboard body upper surface and is arranged on keyboard body inside, and the inwall of described button is provided with the light emitting diode that is connected with circuit board.
The keyboard body upper surface is provided with pushbutton switch, and an end of this pushbutton switch is connected with light emitting diode by the lead that is embedded on the keyboard body, and its other end is connected with circuit board by the lead that is embedded on the keyboard body.This pushbutton switch is controlled the break-make of all light emitting diodes and circuit board.
The starting material of making button are the polymethyl methyl esters, adopt this material, when light emitting diode is bright, a little less than the obstruction effect of button to light.
The utlity model has following advantage and beneficial effect:
(1) button of the present utility model is made by the strong polymethylmethacrylate of light transmission, a little less than the obstruction effect of button to light of being made by this material.
(2) button inwall of the present utility model is provided with the light emitting diode that is connected with circuit board, and the pushbutton switch control light emitting diode by being arranged on the keyboard body upper surface and the break-make of circuit board, when light is dark, pass through the close push button switch, lumination of light emitting diode illuminates keyboard, thereby can overcome light fuzzy problem of keyboard when dark.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of light-emitting device of keyboard, its keyboard body 1 upper surface is provided with more than one button 2, is provided with light emitting diode 3 in the appropriate position of the inwall of button 2.Light emitting diode 3 can directly convert electrical energy into luminous energy, and it has non-friablely, and the life-span is long, the characteristics of power saving.Keyboard body 1 inside is provided with circuit board, and light emitting diode 3 is connected with circuit board, and transmits electric energy for light emitting diode 3 by circuit board.When light emitting diode 3 was luminous, light can shine out by the slit between button 2 and the keyboard body 1, thereby illuminates keyboard.
Keyboard body 1 upper surface also is provided with pushbutton switch 4, and an end of this pushbutton switch 4 is connected with light emitting diode 3 by the lead that is embedded on the keyboard body 1, and its other end can be crossed the lead that is embedded in the keyboard body 1 and be connected with circuit board.The utility model can or disconnect by the closed of pushbutton switch 4 controls the break-make that light emitting diode 3 is connected with circuit board, therefore, can pass through close push button switch 4 when light is dark, and transmit electric energy by circuit board and give light emitting diode 3, thereby make the light emitting diode 3 luminous keyboards that illuminate.
The utility model button 2 is made by polymethylmethacrylate, and its transmittance reaches more than 92%, therefore a little less than the obstruction effect to light, thereby makes the energy consumption of whole light-emitting device low.
As mentioned above, just can well realize the utility model.
Claims (3)
1. the light-emitting device of a keyboard, mainly by keyboard body (1), be arranged on the button (2) of keyboard body upper surface and be arranged on the inner circuit board of keyboard body (1) and form, it is characterized in that: the inwall of described button (2) is provided with the light emitting diode (3) that is connected with circuit board.
2. the light-emitting device of a kind of keyboard according to claim 1, it is characterized in that: described keyboard body (1) upper surface is provided with pushbutton switch (4), and the two ends of this pushbutton switch (4) connect light emitting diode (3) and circuit board by the lead that is embedded on the keyboard body (1) respectively.
3. the light-emitting device of a kind of keyboard according to claim 1 and 2, it is characterized in that: described button (2) is made by polymethylmethacrylate.
