Is it possible to make a keyboard backlight on a laptop. DIY keyboard backlight

In some cases, there is a need to make additional highlighting working surface. Keyboards with backlit keys can be purchased, but if such an option is suitable.

If the price of such devices does not correspond to the capabilities of the user, it is enough to stock up on time and do everything yourself. For such a procedure, you will need some knowledge of working with a soldering iron, connecting a diode tape.

Why do you need a backlit keyboard?

A backlit computer keyboard is essential for people working at night. Night owls often wonder how to achieve keyboard illumination if touch typing has not been mastered. Also, for some operations, there is a need to look at the keys, which is difficult in low-quality lighting.

Additional illumination is necessary for:

IT employees;
gamers;
night shift dispatchers;
technical personnel testing equipment on site with a keyboard connected to the instrument.

Worktop lighting is not only a beautiful fantasy for aesthetic pleasure. The need to see the right keys in the complete or partial absence of light requires a similar measure. Taking care of the correct operation can save time, give an acceptable option for interacting with devices.

In some cases, the desired keyboard option is difficult to obtain, or not possible at all. Taking a variant similar in configuration, it is enough to simply make illuminated keys in it. For such a procedure, you will need some soldering skills and knowledge of the elementary principles of radio electronics.

Required Tools

Reviews of backlit keyboards showcase the various backlit keyboard options:

standard rectangular;
gaming;
laptop keyboard;
wireless counterparts.

To repeat a similar experience, highlighting the standard options without additional special effects, certain tools and materials are needed:

LED strip (up to 1 m);
soldering iron;
batteries (in the case of a built-in backlight recharge option);
network cable (about 3 m);
adapter 2-4-pin to 1-6-pin;
set of screwdrivers;
insulating tape;
switch;
stationery knife;
glue (for some options with changing the keypad);
tester for the final check of the performance of all elements of the circuit.

Almost all the required materials at hand can be purchased at any specialized store. This also applies to LED strips for the Multi-color lighting system.

Backlight power supply

Any illumination option requires a power source. This task remains the number one solution for everyone who wants to create additional special effects on the work surface. It is worth considering the resource consumption of the diode element, since most of the recommendations come down to introducing a connection to the computer's power supply.

A factory-made backlit gaming keyboard for a computer is built on this principle. Since all elements are already included, they directly take a resource on the internal elements of the computer. This process requires a lot of resources.

Masters of electronics suggest making a separate output for connecting a system filter to the socket outlet, or embed an additional power supply to unload the main one. There is some truth in this, since excessive energy consumption wears out your computer.

Benefits of using diode tape

Backlit mechanical keyboards are all built on the principle of using an LED canvas. This approach was preceded by multiple not entirely successful experiments. The choice of diodes was based on the following requirements:

compact arrangement inside the keyboard box;
light weight;
ease of installation;
resource consumption;
convenience when replacing a worn element;
requirements for the brightness of the light source;
resistance to multiple mechanical damage;
the ability to add additional colors.

The last point is important for the built-in Multi-color system. Gaming keyboards or laptop panels require contrast backlighting. This is due to the requirements of the orientation of the gamer or tester in the process. Areas painted in different light colors allow you to quickly orient yourself and prevent confusion. In addition, LEDs interact harmlessly with computer or laptop systems.

Is any keyboard suitable for transformation?

Any volume keyboard can be suitable for transformation. Backlit gaming keyboards of various configurations all have a certain height. Illumination, not built on the principle of using an LED, is possible only in the factory. Therefore, for a pilot project, it is necessary to take a device of a certain height.

Experienced masters of electronics for the first experiments on installing a light element are recommended to practice on the mechanical keyboards of the following companies:

Asus;
Genius;
A4tech;
Gmej;

These keyboards have sufficient height and simplicity of design. They have a certain margin of safety, since they are designed for the average user.

They can work out a lot of different tricks, including the complete replacement of the key zone with a similar version with transparent inserts. In addition, when compiling several options into one for decorative effects, their standard configuration allows such manipulations.

The backlit wireless keyboard has its own specifics associated with the signaling element. During the addition of such an option to the LED component, it is necessary to perform the following manipulations:

make accurate measurements of all keyboard parameters;
allocate all mounting points on the diagram led strip at a sufficient distance from the impulse boards;
choose a reliable place to mount the battery;
decide how the backlight will turn off / on;
make some changes in the case to display the button.

The main objective of this process is to install the tape without damaging the main functions of the keyboard. When dismantling the keypad, you need to remember the main rule that applies to all other keyboard options:

If the rubber pads are peeled off, they cannot be reinstalled correctly. There is an additional option of fastening to a transparent backing sheet, however, in some sensitive models, this will lead to a complete lack of key response when pressed.

Where can I get LED strip?

To solve the question of how to turn on the backlight of the keyboard, you must have an LED canvas. The standard version of the tape is sold in all hardware stores and markets. If the project development conditions for installing the backlight require any special properties or requirements, analogues can be found through Internet sources.

The standard tape consists of:

elastic polymer tape;
a series of series-connected diodes;
outlet points of power connection elements;
separation zone marked with special markings.

In the ribbon options for the Multi-color system, it has some differences. Diode pairs different colors connected in parallel at some distance opposite each other. Otherwise, all soldering (connection) points for twisted pair wires have a standard output.

According to the markings, one output point has 5 volts, the other 12 volts. This must be taken into account when connecting the lighting circuit to the connectors. In addition, with the option of connecting the web through Charger, it must be borne in mind that the memory must be transformer, not pulse.

Turn on keyboard backlight on Asus laptop

One of the frequently asked questions is how to turn on the keyboard backlight on an Asus laptop. Since models of this type have a very moderate glow. Some users are not satisfied with the quality of the luminous element. However, the machine itself suits in terms of its parameters and quality of work.

To install the LED element, you should immediately decide on the type of lighting. For novice electronics engineers, it is recommended to make the backlight along the contour. Since this will minimize the possible damage to performance during inept installation.

The rules for installing a diode tape require:

disconnect the battery;
remove all fasteners (some are recessed and hardly noticeable at first glance);
gently pull out the hard drive;
dismantle DVD ROM;
release the key panel from fasteners;
disconnect the display cable suitable for the motherboard;
disconnect the cable;
remove WLAN.

The LED strip itself must be installed along the free contour of the edge of the keyboard. When doing this, take into account the place of fastening of the battery or any accumulator that is flat enough to be mounted in the housing. One of the inconvenient moments of such a process will be the need for a similar dismantling when replacing the power element.

No. 1 The easiest way to highlight

Attach the tape to the bottom of the monitor or the inside of the keyboard drawer. This is one of the most simple options how to make a backlight on the keyboard. This method is suitable for those who are not familiar with the principles of electronics. The installed bar has a simple connection type:

a twisted pair (similar to an Internet connection wire) is soldered to the output points of the internal connection of the diodes;
connection via a molex power connector to the hard drive;
the connector with yellow marking is rated for 12 volts;
the connector with the red marking is reserved for 5 volts.

Mounting can be done inside the tabletop, which gives bright illumination of the surface of the keys. In a similar variant, a switch can be attached under the surface of the table top, with which you can turn off the lighting during the daytime.

Switch fixture

In various systems, an important point is to turn off the backlight at a time when it is not needed. If it's about standard keyboards mechanical type, then everything is simple. An additional groove is cut in the case, where the off button is displayed. Accuracy and aesthetics depends on your efforts.

In models with a more complex structure, this approach does not have its functional meaning. Since damage to the integrity of the case can affect the operation of the entire device. On laptops, this option is in principle not acceptable.

Factory backlit keyboard models are equipped with special keys to turn off the backlight. Such keys have an additional LED on the case, which does not shine if the backlight is turned off. This principle can be applied to turn off a homemade keyboard backlight LED circuit on a laptop.

Keyboard key illumination principle

The light from the diodes reaches the surface in two ways:

through the gaps between the keys;
through the transparent parts of the keys.

You need to pay attention to this when working with the keyboard. Neon lights considered the most optimal and correct. The light source gives an even beam, which has a clear scattering radius. This option is especially well observed if the symbols themselves glow.

On standard keyboards, all buttons are not transparent. You can correct the situation by sawing out the area of \u200b\u200bthe working surface and replacing it with a more progressive one. With such manipulations, it is worth considering the moment of coincidence of the location of the button area.

Also, a similar process requires accuracy when processing joints and fitting to the hole area. A new panel with keys is glued using specialized glue. It is necessary to carefully monitor the joints so that the structure is taken tightly. In any case, the light supplied by the diode is reflected from the hands, creating additional illumination of the panel.

№2 Installation of LEDs in the body of the keyboard 760

Before installing backlight tapes, you need to draw up a diagram of all exit points for additional elements. This applies to:

switch;
wires to the power supply;
console system connection for Multi-color.

Thus, the diagram must necessarily include:

exit points for additional wires;
the location of the rubber substrates of the keys;
points of internal fastening of all wiring, connections.

Since all the planks are connected in one knot, a thoughtful plan is needed for laying this part. So that its volume does not interfere with the installation of the panel with keys.

Do-it-yourself keyboard backlighting requires some accuracy. When mounting the tape, the first task is to dismantle the housing. All fasteners must be carefully disconnected, paying attention to the possible outputs of the various connectors.

In the case of a solid keypad, it makes sense to melt the holes for the output of the diodes with a soldering iron. For such a manipulation, it will be necessary to accurately calculate the location of the diode along the guide and the attachment points of the keys. It makes sense to attach the wire connected to the beginning of the circuit with adhesive tape to the main keyboard wires for greater ease of use.

A connector adapter is mounted on the wire for the power wires of the diode tape. We connect it directly to the power source. The button for turning off the backlight can be inserted into the exit point of the boards by breaking one bar.

Multi-color rainbow-colored keyboard backlight

The multi-color backlight system is based on the use of an RGB diode strip. For this option you will need:

keyboard with transparent key symbols;
RGB diode tape;
RGB controller designed for 12v;
power unit;
mode switch panel;
power connector;
signal receiving sensor.

Tapes are dissolved into the required segments. They are attached in a well-defined place under the keys. Connected in parallel, connected to the controller. Additionally, a remote control signal reception sensor is displayed. A groove is cut in the case to remove the power connector. When the final preparations are made, the body is assembled.

A feature of this design is ease of manufacture, low cost and easy availability of materials, practicality and invisibility. The backlight unit is fixed on the bottom of the tabletop and, when switched on, illuminates the keyboard and the “near-keyboard” space very well. The computer will act as a power source for the backlight unit, because at the time when you need to illuminate the keyboard, it is usually always on.

We make a backlight for the keyboard powered by computer ports

First, a little about the materials and details that were used in the manufacture of the structure. LEDs were used as light sources due to their reliability and low consumption. I used eight bright bluish 3.5 mm LEDs: I just went to a store that sells radio components and bought the ones that I liked. I chose based on the following principles: the color of the glow (almost all colors of the rainbow are available), the minimum possible dimensions and supply voltage (you need LEDs that burn confidently at a voltage of about 3 volts, by the way, most of them; use instances powered by 12 volts in this design, I think, inappropriate). Unfortunately, I can’t name the brand of LEDs, because. even the sellers themselves do not know it, the quantity (8 pcs) will be explained below. Tests have shown that the selected LEDs glow very brightly at a voltage of 3 - 3.5 volts, the lower glow threshold is about 1.8 volts. It is very important to purchase LEDs all at once in one place: this will give at least some guarantee that they will all glow with the same brightness at the same current consumption.

It is also necessary to purchase any switch (tumbler) for two positions - “on” and “off”, I chose it, also, based on the minimum dimensions. A section of an electrical box for wiring was used as a housing for the backlight unit. It can be purchased at an electrical store for almost a penny. The section (height*width) of the box was chosen as small as possible, look at several options and take the one that suits you. By the way, here you can turn on your imagination and use something else that is suitable in size as a case. I settled on an electrical box, due to its availability, I didn’t want to invent something special: all the same, the backlight housing itself under the tabletop will be almost invisible.

Well, now about the most important thing: about the nutrition of this design. As mentioned above, the backlight will be powered from one of the computer's peripheral ports. In principle, there may be several options, but it is better to focus on two: USB or IEEE1394 (FireWire), these ports are available in almost any computer. It all depends on which of them are less in demand on your PC. For example, I have almost all USB port We are busy, but there is a couple of free FireWire, based on this, IEEE1394 was chosen for power (see diagram above). The voltage at the output of the FireWire computer port is 12 volts, hence the number of LEDs used. With a series connection of 4 pieces (with a voltage of about 3 volts each), we get the coveted 12 volts. For more uniform illumination of the “near-keyboard” space, it is desirable to increase the number of LEDs, which is why the number 8 turned out (we connect two consecutive groups of four LEDs in each in parallel). We include a resistor in the circuit of each serial chain (resistances R1 and R2 in the diagram - in my case 510 Ohm 0.125 W), Resistors limit the current flowing through the LEDs (in my case, the current is 5mA for one serial chain, the total consumption of the design is 10mA, which , in terms of power, gives us 0.12 W), by changing their resistance, you can select the required brightness of the glow.

The lighting scheme for a keyboard powered by a USB port will look a little different:

The number of LEDs, in this case, can be any (the main thing is not to overload the USB port): it is important to connect a current-limiting resistor in series to the circuit of each of them. By changing the resistance of the resistors, you can get the desired brightness of the glow. With these ratings, the current through the LEDs, as in the first case, is limited to 5mA, as a result, the total consumption is 40mA or 0.2 W in terms of power.

The resistance values on the first and second diagrams are given approximately, these turned out to be for the LEDs I have, with a glow brightness that is comfortable, again, for me: you may get slightly different values. It is best, at the time of setting, to connect assembled circuit to an external voltage source of 5 or 12 volts, respectively, check the operability and, if necessary, adjust the brightness of the LEDs, only after that connect the device to your computer.

You can get a general idea of the design of the backlight unit by looking at the photos (click on the photo - an enlarged image will open in a new window). To connect to a computer, standard cables are used (in the first case, the IEEE1394 6pin - 6pin cable, photo above; in the second USB A - USB A. On the one hand, the connectors are cut off, the wires are cut to the required length and soldered to the desired circuit points. Unused wires must be carefully insulated relative to each other and from the shielding braid of the cable.

In principle, as you can see, there is nothing complicated in the design and installation, just be patient and careful. Once again I want to remind you: we must turn on the first time from an external power source, check, adjust the brightness, etc. assembled structure fasten with self-tapping screws to the bottom of the tabletop: for better light reflection, the surface in this place can be pasted over with sticky aluminum foil. After that, we connect the structure to the computer and, with pleasure, use it.

In some cases, there is a need to make additional illumination of the work surface. Keyboards with backlit keys can be purchased, but if such an option is suitable. If the price of such devices does not correspond to the capabilities of the user, it is enough to stock up on time and do everything yourself. For such a procedure, you will need some knowledge of working with a soldering iron, connecting a diode tape.

How to turn on the keyboard backlight on Asus, Lenovo, Hp, Acer laptops, do-it-yourself backlighting

Keyboard backlighting is one of the necessary features that allows you to work with a laptop in rooms with low light levels or at night. This option has long passed from the category of "whims" and is increasingly taken into account when choosing a device.

How to turn on the backlight

Not all laptop owners are aware of the presence / absence of backlit keys on their laptops. To check, you must first pay attention to the top panel of the keyboard. Many manufacturers add special functions to the optional "F1-F12" row, marking them with the corresponding icons.

If there are no icons, then you can try the Fn + F1-F12 button combination. It is worth considering the fact that in addition to backlighting, the “F” row can also cause sleep mode or, for example, turn off the screen. If you mistakenly called the wrong action, just repeat the last combination and everything will return to its place again.

Also, this option can be called by the key combination "Fn + space (space)" or "Fn + right arrow".

Enabling and disabling the function in different models

Different brands and models of laptops differ in how they turn on the backlight, if any.

Asus. While holding the Fn key, press F4 in parallel and enjoy the flickering letters on the working panel. To disable, we type the combination "Fn + F3".

Lenovo. On the "space" key of the laptop keyboard of this manufacturer, a flashlight is often drawn, which gives a hint. Simultaneously pressing "Fn + Space" activates the function.

Acer. The combination of buttons "Fn + F5" controls the inclusion and deactivation of the keyboard backlight.

DIY lighting

If the manufacturer of your device does not provide backlighting, then there are two options for solving the problem - order a finished one or do it yourself.

Memory card reader - what is it

If for the keyboard of a stationary computer you can contrive and design both external and internal lighting, then you don’t have to choose for a laptop. To illuminate work panel laptop you will need:

any color LED
100 ohm resistor
USB plug
soldering iron and glue

USB pinout

The 1st and 4th pins of the USB plug are "plus" and "minus" respectively, and the 2nd and 3rd are for data transfer.

Do you often work at your computer in the dark? LEDs under the keys are what you need

To date, the backlight of a laptop keyboard is for many a determining factor in the purchase of this gadget. After all, this is a useful and convenient feature for lovers of work and leisure at night or in poor lighting conditions. But few users know how the keyboard backlight on a laptop turns on and what can be done if this model does not have one.

It is worth noting that there are several ways to enable this useful feature. Differences exist depending on the manufacturer and specific model devices. It should not be forgotten that the majority budget models there is no such useful function, but do not be too lazy to check it again.

It is also possible to manufacture the backlight yourself: all parts can be bought in specialized stores. And then you need a few simple steps. Or you can order a similar device in an online store - it will cost not such and big money.

How to turn on the keyboard backlight on a laptop

The first step is to determine if your laptop has a keyboard backlight feature. If it exists, then the whole process is to press a special key combination. Each manufacturer in this case assigns its own button, but it is necessarily among the keys of the top row F1-F12. You can watch them Special symbols applied in a different color (usually blue or red).

In order to turn on the keyboard backlight on a laptop (Acer, HP, Dell, Samsung, MSI and others), you need to hold the Fn button (it is located in the lower left corner) and press an additional key that is unique to each manufacturer. The exact information can be found in the user manual. It should be remembered that by experimenting with key combinations, you can disable or enable a number of other device functions (disable WiFi mode, put the laptop to sleep, turn off the screen). You can undo changes by pressing the used keyboard shortcut again.

If you are sure that this function exists, and the desired combination does not include it, then make sure that the Fn button works (for example, by trying another keyboard shortcut you know). Check for appropriate drivers, BIOS settings(Setup Utility - System Configuration - Action Keys Mode - Enabled), try to activate the button with the Fn + NumLock combination.

As already written, different manufacturers different combinations are responsible for the LEDs (we give a few examples):

How to turn on the lighting on an HP laptop - Fn + F5.
How to turn on the lighting on the ASUS n76v laptop - there are three brightness levels, Fn + F3 and Fn + F4.
How to turn on keyboard lighting on a Lenovo laptop - Fn + Space (space).

In addition, you can make external LEDs yourself. To do this, all you need is knowledge of electronics, an LED, a resistor, and a little time. However, it is worth considering that it is much easier and safer to purchase this accessory. Because if you close electrical circuit on the wrong side, then not only will you not achieve the desired result, but you also risk ruining your computer.

As you can see for yourself, LEDs are an incredibly useful and convenient device. If you do not have it by default, you can always purchase additional equipment, as well as attach it to your laptop. And thanks to our tips, you can do it easily and quickly.

How to turn on the backlight on a laptop

If you often work on a laptop at night, and even in poor lighting, you will surely be pleased with the ability to backlight the keyboard on a laptop. This surprisingly useful feature appeared relatively recently, it is used for new models of equipment. Turning on the backlight is not difficult at all, it will not take you much time.

First, determine if your laptop has a backlight feature. On cheap models, it may simply not be. Information about the presence of backlight can be seen in the instructions for the laptop. Then see if any key has a backlight icon - a light bulb and keys. At different models it can be a different button. Most often, such an icon is located on the F1 - F12 line. If you find it, then use it to activate the backlight along with the Fn key. Separately, the backlight button will not work.

If the icon is not visible, you will have to sort through the possible combinations. After checking all the keys Fn + F 1 ... 12, try Fn + space, Fn + F6 + right arrow.

Keep in mind that during the search process, pressing key combinations may activate various functions. This can be turning off the monitor, turning off Wi-Fi, switching to sleep mode. To cancel an action, press the same combination again.

Before buying a backlit laptop, make sure that both the English and Russian layouts are highlighted. Some manufacturers produce separate backlit laptop keyboards. So, if your laptop does not have this feature, you can buy another keyboard and replace it by contacting service center.

Instructions: how to turn on the keyboard backlight on an Asus laptop

Most older laptop models do not include keyboard backlighting, and this is perhaps the biggest disadvantage of manufacturers, because at night it is simply not possible to fully work on a laptop. Currently, in new models, the backlight has begun to be installed on the keyboard, but not many users have been able to figure out how to turn on the backlight of the keyboard, so today we will talk about just that. Of course, without any doubt, we can say that the keyboard backlight is a very convenient option, because even in the dark you can fully work on your device.

Management

If you are looking for a solution on how to turn on the keyboard backlight on Asus laptop then carefully read the instructions that we will now give you. You probably know where the special "Fn" button is located on your keyboard, but you may not know what it is for. This key can be attributed to an additional type, but you can turn on and turn off the keyboard backlight on your device using it. In fact, on all laptop models, using this key, you will clearly see the buttons even in the dark, so if the keyboard backlight still does not work for you (Asus laptop, for example), then you should get acquainted with other proposed solutions to this issue. , which will be described below.

Special combinations

In order to solve the problem, you will need to choose the correct key combination on the keyboard if the additional "Fn" button did not work. It is necessary to try to press all the buttons from the top row, starting with "F1" and ending with "F12". On each additional key you will be able to see certain value, for example, you can use these switches to adjust the sound, adjust the screen brightness, and make other changes. Most likely, additional lighting will be located in this row. In order to learn how to turn on the keyboard backlight on an Asus laptop, you will definitely need to experiment. First of all, we hold down the "Fn" key, after which we begin to press additional buttons in order. You can first look for the keyboard icon on the additional layout, but if you didn’t notice such a designation, then you should try the experimental path.

Additional features

You must also remember that while you are deciding how to turn on the keyboard backlight on an Asus laptop, you can use other options, such as turning off the screen or going to sleep. In order for the undo of these operations to work, you just need to press the combination again and everything will return to its place.

No pointer

In some cases, it may be that pictures with a keyboard on additional keys just not, and after trying all sorts of options, you still couldn't figure out how to turn on the keyboard backlight on an Asus laptop. But if you know exactly what given function your device has it, then you should not give up and try other options. Try "Fn" plus "Space" combinations. Also, the first key can be tested in conjunction with the "Right Arrow" or "F5". If you want to know how to turn on the keyboard backlight (Asus laptop), but it turned out that such an opportunity is not provided, do not despair. Anyone can create the necessary lighting with their own hands, of course, you will have it external, but still you can see the keys perfectly. In order to achieve the result, you will need to use one or more LEDs. You also need a USB port. You can use just one LED, but in that case, your backlight will not help you see the entire keyboard.

Finishing touch

USB power provides five volts, and accordingly you need to choose the same power and LED. Or just use a resistor. For example, if you chose an LED that requires a power of 3.5 volts, then we select it for 1.5 volts. It is important to remember one more thing. One LED may not be enough, in which case you need to use several at once. You can do this with a parallel connection. Experts in practice tested the maximum number of these elements that can be connected to one USB output. In total, this number equals 25 diodes, so if you want to connect 5, then you can safely do it. If you yourself cannot figure out how to make manual backlighting correctly, then you should contact specialists who can even make internal lighting in a laptop, but such services will cost you extremely expensive. Although in practice the connection is very simple and you will not need to devote much time to developing such a function.

When typing in the dark, whether it is text or correspondence on the Internet, it always turns out not to understand what. I don't have blind printing. So I'm constantly looking for a way to highlight the keyboard. My previous designs were battered by time and helped by a small child.
The structure will be height adjustable. You don't need to make it especially high.
Everything is made from available non-rare parts.
For manufacturing we need:

- axis from the printer;
- halogen lamp;
- a piece of LED strip;
- two-core wire;
- pin;
- single-core copper wire;
- plywood or chipboard;
- epoxy adhesive;
- drill, soldering iron, self-tapping screws.

Making a backlight for a computer keyboard

To begin with, the printer axis must be freed from the rollers. They sit very firmly, but if you help with a hammer, they are removed quickly. In extreme cases, you can cut down. The main thing is not to damage the axle coating, it will quickly rust.

On a single-core copper wire, I have a 2.5 square mm mounting wire, we make a ring for a 4 mm screw. Set aside at this stage.

I took a meter and a half power cord. A large wire is not needed, the current is small. I have a double wire with a core diameter of about 0.25 square mm. applied what is, it is possible and thinner. The backlight is powered by 12 volts taken from computer block nutrition. The wire simply goes into any hole in the system unit and connects to the black and yellow wires. It can also be powered from an external 12 volt power supply and current under a lamp or LED strip.

The reflector of this design is very convenient. We take a burnt one, you can also a new one, halogen lamp and carefully knock out the glass. Be careful, the glass can bounce into the eye, follow the safety precautions.

Cut off a piece of 40-60 mm from a single-core wire. At the end we make a bend and insert it into the reflector. Insert the power cord there. All this is filled with epoxy glue. Frozen, the wires sit securely and will not fall out.

For aesthetics, we will make a twisted wire. I will have it curling along the backlight stand. During the manufacture of the structure, another axis was taken from the printer, which had diameter transitions. By cutting them off, the axle is exposed to rust. So I took another axle.
To make a twisted wire, you need to wrap the wire tightly around the axis and warm it up. I did it with an industrial hair dryer, you can warm it up over gas stove. Set aside to cool the wire.

Glue a piece of LED strip into the reflector. Wires are protected and soldered. Double-sided tape was bad, glued the tape with super glue. Holds up great.

I make the basis of the design from different scraps of chipboard. It can be made from anything: plywood, OSB, etc. I make a round shape. I cut out with a crown on plywood and drywall.
The middle ring is in the form of a donut, a switch and part of the wires will be installed there.

He processed the base blanks and twisted them together. At the end of the middle blank, a donut, I made a cut for the switch.

I made a hole in the top circle, where the power wire will be inserted later. I drilled a hole for the wire between the bottom and middle circle. Drilled at an angle.

Thinking about painting. Decided to paint it matte black.

I attach the power switch with epoxy glue. A lot of it is not needed, if the glue is good, then it is kept in a small amount.

While the glue hardens, we proceed to the assembly of the reflector. I drill a through hole in the clothespin. With a 4 mm screw, we twist everything together, not forgetting about the grower.

We pass the wire into the hole, after winding the wire onto the axis. We clean the insulation of the wire and cut one wire. The resulting wire break is soldered to the switch. We isolate.

We twist the base into a single structure.

We test by temporarily connecting 12 volts to the battery.
It turned out great. Adjustable in height to fully illuminate the keyboard.

Here we have such an excellent backlight for the keyboard. More than enough light. In general, I advise you not to throw out such reflectors, which are very useful after a burnout.

Many computer users have encountered such a problem when they need to work at the keyboard at night and at the same time they cannot turn on the light in the room. This usually occurs in those people who live with parents or have small children. Although most users prefer to work at a computer in the dark because of the more contrasting 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 it is impossible to see the signs written on the buttons, so you have to put the keyboard closer to the monitor or turn on the light. Some manufacturers took into account this feature of work and launched the production 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. Such a keyboard backlight is very convenient, but has a significant drawback, since novice users do not have “blind” typing, which means they constantly look at the keys through which the light comes. This has a negative effect on vision and with prolonged use of such a device, one feels

Do-it-yourself keyboard backlighting solves both of these problems. The fact is that it is done by the user himself, which means that all the necessary points can be taken into account in the manufacturing process. In this case, there are two most common methods for manufacturing such a backlight.

The first method involves the presence of a special computer table, which is equipped with a special keyboard shelf located under the table top. Such a keyboard backlight is made from or a group of LEDs, which 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 second end of the wires coming from the LED can be soldered in place of the keyboard light, which lights up when the “Scroll Lock” key is pressed. Thus, when you press this key, the lighting will be turned on, and when you press it again, it will turn off. This light is very comfortable and easy to control.

If you need backlighting for and at the same time do not want to lose mobility, then you can use the most simple method. It is necessary to purchase a small and low-power flashlight that has a clip-on mount. It can be mounted on a laptop in a user-friendly position and turned on if necessary. If finding a flashlight with a clip is problematic, then you can use an ordinary small flashlight and you can also use special USB-powered flashlights.
