Many computer users have encountered such a problem when you need to work at the keyboard at night and you cannot turn on the lights in the room. This usually happens in people who live with their parents or have small children. Although most users prefer to work on a computer in the dark because of the more contrasting visibility of the monitor. In this case, the keyboard backlight in such cases is simply necessary.
The fact is that in the dark you can not consider the signs written on the buttons, so you have to put the keyboard closer to the monitor or turn on the light. Some manufacturers of computer equipment have taken into account this feature of work and launched the release of special keyboards or laptops that have internal backlighting. In this case, the light exits the keyboard itself through the holes in the buttons, which are made in the form of letters. Such a keyboard backlight is very convenient, but has a significant drawback, because novice users do not have a “blind” typing, which means they constantly look at the keys through which the light goes. This adversely affects vision and with prolonged use of such a device, eye fatigue is felt .
Doing both of these problems do-it-yourself keyboard backlighting. The fact is that it is done by the user himself, which means that in the manufacturing process you can take into account all the necessary points. However, there are two of the most common methods for making such a backlight.
The first method involves the presence of a special computer table, which is equipped with a special shelf for the keyboard, located under the table cover. This keyboard backlight is made of LED strip or a group of LEDs that are fixed under the table top, above the shelf with the keyboard. Connect it through the power supply with the appropriate voltage.
The second method assumes that the keyboard backlight will be mounted directly on it. To do this, flexible hoses with wires are attached to it, at the end of which an LED is soldered. These hoses are bent in the form of street lamps, which should illuminate the place the user needs. The other end of the wires coming from the LED can be soldered to the keyboard light, which lights up when you press the “Scroll Lock” key. Thus, when you press this key, the lighting will be turned on, and when you press it again, it will turn off. This backlight is very convenient and easy to control.
If backlighting is needed for a laptop keyboard, and you don’t want to lose mobility, you can use the simplest method. You need to purchase a small and low-power flashlight, which has a mount in the form of a clip. It can be mounted on the laptop in a position convenient for the user and, if necessary, turned on. If it is problematic to find a flashlight with a clip, then you can use the usual small flashlight and double-sided tape. You can also use special flashlights powered by USB.
