Abstract
本实用新型公开了一种能够自动调节键盘亮度的笔记本电脑，包括笔记本电脑、键盘背光灯、单片机及环境光传感器，其特征在于：环境光传感器和单片机内置于笔记本电脑的内部，键盘背光灯固定于键盘上；所述的笔记本电脑制作有显示屏、键盘及触摸板；所述的环境光传感器将键盘周围的光线强度转换成电信号传递给单片机，单片机根据收到的信号值控制键盘背光灯的电压值，达到调节键盘背光灯亮度的功能，方便人们打字。该实用新型较传统的笔记本电脑仅添加了键盘背光灯、单片机及环境光传感器，以较低的成本解决了人们的一大难题，推广更容易。
The utility model discloses a notebook computer capable of automatically adjusting the brightness of a keyboard, which comprises a notebook computer, a keyboard backlight, a single-chip microcomputer and an ambient light sensor. On the keyboard; the notebook computer is made with a display screen, a keyboard and a touch panel; the ambient light sensor converts the light intensity around the keyboard into an electrical signal and transmits it to the single-chip microcomputer, and the single-chip microcomputer controls the keyboard backlight according to the received signal value The voltage value can achieve the function of adjusting the brightness of the keyboard backlight, which is convenient for people to type. Compared with traditional notebook computers, the utility model only adds a keyboard backlight, a single-chip microcomputer and an ambient light sensor, solves a major problem of people at a lower cost, and is easier to popularize.
Description
Technical field
The utility model relates to a kind ofly can regulate the notebook computer of keypad brightness automatically, and consciously perception external environment of this utility model light intensity is regulated the brightness of KBD-LIGHT automatically, is convenient for people to typewriting.
Background technology
Nowadays, become must an obligato part in people's work, study and the entertainment life for notebook computer.Sometimes and since in the external environment light a little less than, the letter on the keyboard is difficult for seeing clearly, when seeing a film especially at night or when using the computer slide show, better for effect, much human is selected not turn on light, typewriting at this moment is unusual difficulty just.If can make the intensity of light in the consciously perception external environment of computer, the intensity of regulating KBD-LIGHT automatically when being convenient for people to typewrite, does not influence the result of broadcast of film or lantern slide again, will receive people's welcome deeply.
Summary of the invention
In order to address the above problem; The utility model provides a kind of can regulate the notebook computer of keypad brightness automatically; Comprise notebook computer, KBD-LIGHT, single-chip microcomputer and ambient light sensor; Ambient light sensor and single-chip microcomputer are built in the inside of notebook computer, and KBD-LIGHT is fixed on the keyboard; Ambient light sensor converts the light intensity around the keyboard to electrical signal transfer and gives single-chip microcomputer, and single-chip microcomputer reaches the function of regulating the keyboard brightness of backlight according to the magnitude of voltage of the signal value supervisory keyboard backlight of receiving.The intensity of light in the consciously perception external environment of this utility model, the intensity of regulating KBD-LIGHT automatically when being convenient for people to typewrite, does not influence the result of broadcast of film or lantern slide again, has solved a great problem when people use computer.
The utility model is realized through following technical scheme: a kind ofly can regulate the notebook computer of keypad brightness automatically; Comprise notebook computer, KBD-LIGHT, single-chip microcomputer and ambient light sensor; It is characterized in that: ambient light sensor and single-chip microcomputer are built in the inside of notebook computer, and KBD-LIGHT is fixed on the keyboard; Described notebook computer is manufactured with display screen, keyboard and touch pad; Described ambient light sensor converts the light intensity around the keyboard to electrical signal transfer and gives single-chip microcomputer, and single-chip microcomputer reaches the function of regulating the keyboard brightness of backlight according to the magnitude of voltage of the signal value supervisory keyboard backlight of receiving.
The good effect of the utility model is: this utility model comprises notebook computer, KBD-LIGHT, single-chip microcomputer and ambient light sensor, and ambient light sensor and single-chip microcomputer are built in the inside of notebook computer, and KBD-LIGHT is fixed on the keyboard; Ambient light sensor converts the light intensity around the keyboard to electrical signal transfer and gives single-chip microcomputer, and single-chip microcomputer reaches the function of regulating the keyboard brightness of backlight according to the magnitude of voltage of the signal value supervisory keyboard backlight of receiving.The intensity of light in the consciously perception external environment of this utility model, the intensity of regulating KBD-LIGHT automatically when being convenient for people to typewrite, does not influence the result of broadcast of film or lantern slide again, has solved a great problem when people use computer.The notebook computer that this utility model is more traditional has only added KBD-LIGHT, single-chip microcomputer and ambient light sensor, has solved people's a great problem with lower cost, and it is easier to promote.
