Embodiment 1

[0014] Such as figure 1 A computer keyboard that can automatically illuminate keys is shown, including a keyboard body 1 and an internal power supply circuit of the keyboard. The keyboard body 1 is provided with an LED lighting lamp 2, a photosensitive switch 3, and a touch delay switch 4 that are electrically connected in sequence. , the photosensitive switch 3 and the touch delay switch 4 are electrically connected to the internal power supply circuit of the keyboard; The photosensitive switch 3 in this embodiment outputs a switch value short-circuit signal (that is, the switch is open state) when the brightness of the ambient light is lower than the default value of the illuminance, and outputs a switch value open circuit signal when the brightness of the ambient light is higher than the default value of the illuminance ( That is, the switch is closed). With the cooperation of the photosensitive switch 3, the touch delay switch 4 in this embodiment can make the light switc...

Embodiment 2

[0016] On the basis of Embodiment 1, the number of the LED lighting lamps 2 is eight, and they are arranged horizontally on the upper end of the keyboard main body 1 in sequence. The LED illuminating lamp 2 is provided with a lampshade 5 that can reflect light to the keys. The photosensitive switch 3 is arranged on the upper right corner of the keyboard body 1, and the touch delay switch 4 is arranged between the small keyboard area and the main keyboard area. Setting several LED lighting lamps 2 can ensure that the keyboard is evenly illuminated when the light is dark, and it is arranged on the upper end of the keyboard so that the hand’s irradiation of the light will not cause too much influence when operating the keyboard. Direct exposure to the eyes, and the light can be more fully irradiated to the keyboard. The setting position of the touch delay switch 4 is favorable for it to be touched conveniently.

Abstract

The invention belongs to the technical field of computer hardware, and particularly provides a computer keyboard capable of automatically lighting keys. The computer keyboard comprises a keyboard body (1) and an in-keyboard power circuit. The keyboard body (1) is provided with LED illumination lamps (2), a light activated switch (3) and a touch delay switch (4) which are electrically connected in sequence. The light activated switch (3) and the touch delay switch (4) are both electrically connected with the in-keyboard power circuit. The lower end of the keyboard body (1) is connected with a keyboard dust hood (6) through hinges (7), and the keyboard dust hood (6) can be turned to the back face of the keyboard body (1). Due to the LED illumination lamps and the keyboard dust hood, the computer keyboard overcomes the defects that in the prior art, when a keyboard is used in a dark environment, needed keys are difficult to find, and the keyboard does not have the dust removal function, convenience is brought to people for use of the keyboard, and the working and study efficiency of people is improved.

Description

technical field [0001] The invention belongs to the technical field of computer hardware, in particular to a computer keyboard capable of automatically illuminating keys. Background technique [0002] Computer has become an indispensable tool in people's work and study. Its convenient text input and file editing functions have replaced a lot of paper writing, but the current computer keyboard still has some inconveniences in the input and use. For example, for general For users, there are many keys that need to look at the keyboard with eyes to find the exact position and then press them with fingers. When the ambient light is dark, it will be difficult to find the specific position of the key on the keyboard, which will cause inconvenience to use and will cause problems. cause incorrect input. In addition, when the keyboard is not in use, the key surfaces are exposed in the air, and dust and garbage residues are likely to fall into the keyboard, affecting the use of the ke...
