Many computer users have come acrosssuch problem when it is necessary to work behind the keyboard the night and thus it is impossible to include light in a room. Usually this happens in those people who live with their parents or have young children. Although most users prefer to work at a computer in the dark because of the more contrast visibility of the monitor. In this case, the backlight of the keyboard in such cases is simply necessary.
The fact is that in the dark can not be consideredsigns written on the buttons, so you have to put the keyboard closer to the monitor or turn on the light. Some manufacturers of computer technology have taken into account this feature of the work and have established the production of special keyboards or laptops that have internal illumination. In this case, the light comes out of the keyboard itself through the holes in the buttons, which are made in the form of letters. This backlighting of the keyboard is very convenient, but it has a significant drawback, since novice users do not have a "blind" set of text, which means they constantly look at the keys through which the light goes. This adversely affects the eyesight and when the device is used for a long time, the eyes are tired.
Solves both of these problems by highlighting the keyboardown hands. The fact is that it is made by the user himself, which means that during the manufacturing process you can take into account all the necessary moments. In this case, there are two most common methods for making such a highlight.
The first method assumes the existence of a specialcomputer desk, which is equipped with a special shelf for the keyboard, located under the table top. This backlight of the keyboard is made of LED tape or a group of LEDs, which are fixed under the table top, above the shelf with the keyboard. Plug it into the power supply with the appropriate voltage.
The second method assumes that the backlightingThe keyboard will be mounted directly on it. For this, flexible hoses with wires are attached to it, at the end of which the LED is soldered. These hoses are bent in the form of street lights, which should illuminate the user's desired place. The second end of the wires coming from the LED can be soldered to the position of the keypad, which lights up when the "Scroll Lock" key is pressed. Thus, when this key is pressed, the lighting will be turned on, and when it is pressed again, it turns off. This backlight is very convenient and easy to control.
If you need a backlight for the keyboardlaptop, and at the same time do not want to lose mobility, then you can use the simplest method. It is necessary to purchase a small and low-power flashlight, which has a clamp-like fastening. It can be mounted on a laptop in a user-friendly position and, if necessary, turned on. If you find a flashlight with a clamp is problematic, then you can use the usual small flashlight and double-sided tape. You can also use special lanterns powered by USB.
