Description

computer luminous keyboard

technical field

The utility model relates to a computer keyboard device, in particular to a computer keyboard with a light emitting function.

Background technique

The computer keyboard is an essential accessory for the computer. There is basically no light for lighting in the existing computer keyboards. When the lights are turned off at night or when used in a dark environment, it is difficult to see the symbols of the keys on the keyboard. For skilled touch typing users, it is easy to press the wrong key, which is inconvenient to use. In order to improve the above situation, some symbols on the keyboard are made of fluorescent materials, but the effect is not very good, and the display time of the fluorescent materials is also limited, which does not completely solve the above technical problems.

Utility model content

In order to solve the above-mentioned defects in the prior art, the purpose of this utility model is to provide a computer light-emitting keyboard with a light-emitting function, which can clearly see the keyboard in a dark environment.

In order to achieve the above purpose, the technical solution adopted by the utility model is: the computer light-emitting keyboard has a casing and buttons arranged on the casing, and the feature is that: the buttons are made of light-transmitting materials, and LED lights are arranged inside the buttons , the LED light is connected to the keyboard power supply through the printed circuit, and the printed circuit is connected with a control switch.

The control switch is a light control switch.

Beneficial effects of adopting the above technical solution: the keys of the luminous computer keyboard are made of light-transmitting materials, and LED lights are arranged inside the keys. The LED lights are connected to the keyboard power supply through printed lines, and the printed lines are connected with control switches. When the operating environment is dark and the keyboard cannot be seen clearly, turn on the control switch, the LED light inside the key will light up, and the light will illuminate the symbols on the key surface through the key, so that the key can be seen clearly even in a completely dark environment , easy to use the keyboard, avoid misoperation due to unclear keyboard, improve the correct rate of keystrokes, and facilitate operation. The control switch is a light control switch. When the light is good, the light control switch is in the off state, and the LED light in the button is not lit. When the ambient light is dim, the light control switch is automatically turned on, and the LED light is on. Realized automatic induction control.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

The computer luminous keyboard shown in Figure 1 has a casing 1 and buttons 2 arranged on the casing. The thin-film circuit in the casing is placed on the substrate. The thin-film circuit is composed of an upper circuit and a lower circuit, between the upper circuit and the lower circuit. Silicone rubber is provided, and the silicon rubber has a hole corresponding to the position of the button, and a metal shrapnel layer is arranged under the keycap layer formed by the button, and a metal shrapnel is corresponding to the bottom of each keycap. The keys are made of light-transmitting materials, and there are LED lights between the keycap layer and the metal shrapnel layer. The LED lights are connected to the keyboard power supply through printed lines, and the keyboard will emit dim light in the dark, so that everyone With the lights off, the keyboard can also be easily used. A control switch is connected to the printed circuit. The control switch is a light control switch. The backlight at the bottom of the keyboard automatically turns on when the light is too low and turns off when the light is bright enough.
