[0002] The keyboard is an indispensable peripheral device for the computer, but the existing keyboard keys are usually only provided with flanges on the keys such as English letters "F" and "J" for the use of touch typists. Most computer users are used to looking at the symbols on the keyboard to operate, but once the external light is dimmed, it is difficult to find the required operation keys, especially when notebook computer users are operating in the field, because there are generally no other light sources around Auxiliary, when the external light is dim, the operator can only look down for the required operation keys with the help of the weak light of the screen, which is especially inconvenient at this time

The invention discloses a keyboard illuminating device, which is applied to a laptop with a host and a screen. The host is provided with a keyboard, and the keyboard is articulated with the screen. The keyboard illuminating device comprises a switch unit, a telescopic unit, a power supply unit, a photoresistor and a light-emitting unit. When the screen covers the host, the movable part of the telescopic unit is pressed by the screen to retract into the shell of the host, so that a current input path is cut off by the switch unit; and when the screen is raised from the host, the current input path is switched on by the switch unit, the light-emitting unit is shut or started correspondingly by the photoresistor according to the change of the brightness of outside light, and the luminance intensity of the light-emitting unit is adjusted.
Description
technical field [0001] The invention relates to a keyboard illuminating device, more specifically, to a keyboard illuminating device applied to a notebook computer. Background technique [0002] The keyboard is an indispensable peripheral device for the computer, but the existing keyboard keys are usually only provided with flanges on the keys such as English letters "F" and "J" for the use of touch typists. Most computer users are used to looking at the symbols on the keyboard to operate, but once the external light is dimmed, it is difficult to find the required operation keys, especially when notebook computer users are operating in the field, because there are generally no other light sources around Auxiliary, when the external light is dim, the operator can only look down for the required operation keys with the help of the weak light of the screen, which is especially inconvenient at this time. [0003] To sum up, how to provide a keyboard lighting device so that peop...
