Do-it-yourself LED spotlight 10 watts. DIY LED spotlight

Since ancient times, mankind has sought to cope with the light and use it for its own benefit, because, unlike some animals, without special night vision, a person became vulnerable at night. Progress tends to accelerate in a geometric sequence, this statement is absolutely true for the development of lighting technology. For a long time, before the invention of electricity, the only source of light was living fire, then incandescent lamps appeared, and a new era began. Gradually, more and more new types of lamps appeared - fluorescent, halogen, until, finally, the most modern and technological light source appeared - LEDs. At first they were imperfect and far from being as reliable as they are now, and they were very expensive. The situation has changed - LED modules have become affordable, reliable and of high quality. Possessing excellent technical characteristics and operational properties, they are firmly entrenched in the lighting equipment market. In this article, we will talk about a very affordable and simple source of bright, uniform light based on LEDs - an LED spotlight. Characteristics of LED spotlights, how to assemble an LED spotlight with your own hands, how to connect an LED spotlight - we will touch on all this in the process of getting to know this device.

An LED spotlight is a lighting device, the design of which is a voltage converter, a powerful LED, a radiator to remove excess heat and a reflector to amplify and direct the light flux. It can emit, like standard white or warm light, and be colored, with the ability to change RGB colors. The scope of this device is practically unlimited. LED spotlights are used for domestic and industrial purposes, lighting cottages and cottages, lighting entrances and parking lots.

Advantages of diodes over halogen, fluorescent, energy-saving and incandescent lamps

Flashlights based on LED modules have a number of technical and operational advantages over outdated lamp counterparts:

• The main advantage is the low power consumption and high efficiency of devices based on led modules. Consuming 8-12 times less electricity, LED lamps give the same luminous flux in terms of brightness. This is a significant cost savings, and when it comes to industrial scale, when lighting in industrial production is carried out, for example, by a hundred 500-watt lamps that wind energy around the clock, a 10-fold reduction in consumption will lead to enormous cost savings.
• Quality of light emission. Unlike outdated analogues on lamps, LED lights provide the most uniform illumination, devoid of twitching and flickering, over the entire area and range. This is, firstly, the most comfortable environment for the eyes, which does not pose a threat to vision and visual discomfort. Secondly, perfect and undistorted color reproduction, which in many industrial productions can be among the main priorities, in connection with the production activity.
• Durability and reliability. LED modules do not depend in the operational plan on the number of switching on and off. If you are using an LED floodlight with a motion sensor, this point is very relevant. Due to the constant response to movement, the floodlight will constantly turn on and off. LED lamps are designed for 100 thousand or more hours of operation, which is many times more than any lamp. Together with the simplicity and reliability of the design, modern materials that are resistant to mechanical stress, a set of these technical characteristics makes LED lights an ideal choice for lighting any objects, cottages, industrial facilities, houses, streets and squares.

• Safety and environmental friendliness. LED modules are assembled from modern environmentally friendly materials. They do not need any special disposal methods. When the LED flashlight is out of order, you can replace the LED module, and just throw the old one out of its life into the trash can. Absolutely without any fear for your health. The safety of LED lighting equipment is the highest. It works at low currents, which means that if you decide to make the connection yourself and make some mistake and possibly get an electric shock, it will not be as dangerous as in the case of conventional lamps. As for operational specifications, LED modules do not heat up above 90 degrees during operation, which makes them as fireproof as possible.
• Reliability, simplicity and flexibility of use. LED modules can work without damage even with strong power surges. The connection is very simple, almost anyone can handle it. The design of the spotlight is also simple and reliable. In order to replace the module when it has exhausted its service life, it will be enough to unscrew a few bolts and disassemble the searchlight housing. Further, guided by numerous schemes and the help of the Internet, disconnect the old module and connect the new one. Then reassemble the body, place the spotlight back, screwing the body to the mount on the surface where the light was installed. If you need backlighting not only in the standard daytime version, it is enough to purchase a color RGB spotlight, it can change color in a very wide range of shades.

There is only one disadvantage

The only negative is the rather high cost, which is more than completely covered by the combination of pluses. How long the LED lamp will last and the quality of the emitted light, as a result, will lead to significant savings in both money, nerves, and time.

What characteristics are important to know when choosing

To choose the option that suits you, it is advisable to contact a specialist, describing to him the conditions of use, the required lighting range, the required backlight intensity and other parameters that concern you (brightness and warmth of the light flux, the presence of a motion sensor, solar panels for autonomous operation, etc.) .

How to make your own LED spotlight

If you confidently hold a tool in your hands, you have an unnecessary or broken spotlight, and you don’t want to buy a “pig in a poke”, paying a small but significant amount for a cheap Chinese lantern, but you don’t agree to spend a lot of money on an expensive one - assemble an LED spotlight with your own hands. You can even completely solder all the necessary boards, since there are more than enough diagrams and instructions on the Internet. But if you are not ready to resort to a soldering iron, then the next option is just for you.

Required Components

So, what do we need to make powerful LED spotlights:

directly the diode itself, cooling radiators, fans (the smallest computer ones will do) and a power board for them (you can take it from a charger, preferably from a high-quality adapter, because we don’t want the fans to fail), an electronic voltage converter to supply power on our diode and adjust the brightness. We will also need, as previously mentioned, an unnecessary old spotlight - as a body donor, where the entire assembled structure will be installed.

Stage 1 - Beginning of assembly

We begin the assembly procedure by attaching all the elements to a cooling radiator, which is needed to remove heat from a very powerful LED. First of all, you will need to fix the diode module with bolts, using the holes in it. Press the diode firmly onto an even layer of thermal paste.

Then attach the fans, which will be used for additional active cooling, which will reduce the operating temperature by another 10-20 degrees and extend the already long life of the LED.

Stage 2 - Preliminary performance check and temperature measurement

After attaching all the remaining parts, connect the diode to the current source (converter) with wires. Apply current to the diode through a voltage converter to check its operation. Check the operation of the fans and measure the voltage on the power board for the batteries and the fans themselves, it should be the same. To ensure that the cooling system is working properly, it is advisable to accurately measure the temperature using an accurate thermometer such as an infrared heat gun. The temperature should not be higher than 50-60 degrees.

Stage 3 - Putting the entrails into the case

After checking all the components for operability, you need to place the entire structure directly into the prepared case. Don't forget to leave a decent hole at the bottom of the structure - for the fans to blow out heated air, and also at the top - for air intake.

Install the board that controls the operation of the fans (I remind you that it is of high quality, possibly borrowed from the charging adapter) and connect the wires from the fans.

Stage 4 - Final Functional Check

It remains for the last time to check the performance of all the elements, cut out the reflector to the size of the case from a shiny metal (or covered with thick foil) and assemble all the elements of the case together. Having firmly tightened all the bolts connecting the body elements together, you can start using the spotlight on the diode module, which you could make yourself. Naturally, you need to have some experience in working with electronics, circuits and boards, as well as a desire - after all, it will be easier for many to buy a finished device. But a self-assembled spotlight, in addition to the self-proclaimed pride, will have unique technical characteristics. If you use a powerful 100 watt module, it will replace your 600-800 watt halogen flashlight, which would be much larger, would overheat and be very dangerous. The range of illumination by such a spotlight, depending on the chosen angle of the reflector, will vary from very large to huge.

Summary of the article

So let's summarize the above. In order to choose a spotlight, you need to decide in what conditions it will be used - for industrial (warehouse, production lighting) and domestic purposes (yard, cottage lighting), you can choose different spotlights, in accordance with their technical characteristics, including power and color temperature . Based on them, choose a design for the required backlight range, if necessary, choose models with a motion sensor, a solar battery or other options. If you want to make an LED spotlight yourself, select and purchase all the necessary components on the radio market and, armed with a tool, assemble exactly what you need. The key to both approaches is to purchase quality components or equipment from a reputable vendor. This is a guarantee of positive impressions from the future use of the equipment.

Until LED products finally enter our lives and production is fully on track, the price of LED lighting equipment will continue to bite. But why wait or, even worse, overpay if you can assemble a searchlight of the required power with your own hands according to our instructions.

Electrical features of working with LEDs

If you intend to use LED technology, it will not hurt you to learn about some of the intricacies of working with it, which can partly be called disadvantages. On the one hand, LEDs are compact, economical and durable light sources, but on the other?

Solid state semiconductor elements are critically sensitive to high core temperatures. The phenomenon, called degradation, consists in the loss of dopants by the semiconductor, which is expressed in a decrease in the luminous flux or final failure.

a) the design of a conventional LED: 1 - anode; 2 - cathode; 3 - conductor; 4 - crystal; 5 - plastic lens
b) design of a powerful LED: 1 - case; 2 - conductor; 3 - heat sink; 4 - crystal; 5 - lens; 6 - cathode

At a temperature of 60 ° C, the LED degrades very quickly and the 50 thousand hours declared by the manufacturer eventually turn into 3-5 thousand. And the more powerful a single LED, the higher the likelihood of its rapid aging due to overheating. Therefore, when developing lighting fixtures, a high-quality heat removal system is put at the forefront, as well as dividing the emitter into several points and their correct layout.

Another feature of LEDs is that they can only pass a limited number of electrons per unit time. The network that feeds the LED must be current stabilized, otherwise severe overheating and the associated negative consequences occur. The current in the power circuit is regulated by the applied voltage and is limited by a resistor on each of the LEDs. When developing a connection diagram, careful calculation is needed: overestimate the voltage and the LEDs will quickly fail, and make it too low - they will shine at half strength.

The simplest spotlights have only one light-emitting element, but in high-power devices it is recommended to distribute the load for more efficient heat dissipation. In such cases, the connection can be serial, parallel or mixed. The first is not entirely safe: if one of the LEDs burns out, it can either break the circuit or bypass it. With a parallel (and especially mixed) connection, there is a high risk that after one consumer is disconnected from the circuit, the current in the supply network will increase to unacceptable values.

Point sources and matrices: selection, purchase

There are three types of LEDs that are wise to use in spotlights. Please note that when assembling a light fixture from several LEDs, they must be identical both in type and in current-voltage characteristics. It is also recommended to purchase up to a dozen spare diodes as a repair kit and in case of damage during installation.

LEDs in the form of a plastic capsule with pin leads are suitable for making small spotlights and flashlights. This is the cheapest type of product, and the final product will end up being relatively easy to repair.

The second type is ultra-bright white LEDs on a metal substrate. They should be used in high-power lighting fixtures, it is quite simple to remove heat from them.

Another type of LED are high-power LED matrices. It is not recommended to make spotlights with a matrix power of 20 W or more on your own: it will not be possible to effectively remove heat by simple measures.

Housing and reflector parts

There are a number of solutions for the body of a homemade spotlight. If a high degree of dust and moisture protection is required for a street lamp, then a car headlight is suitable. The rim of the lamp base will need to be cut out and fixed over the panel with the LED matrix. The disadvantage of the method is the limited power of the spotlight, despite the fact that only one matrix will fit in it.

If you are placing multiple LEDs or arrays on the same PCB or mounting plate, the enclosure can be made from tin or sheet steel. On the workpiece, mark the development of the truncated pyramid: a square in the center and identical isosceles trapezoids on the sides. Do not forget to leave a “tongue” on one of the sides of each trapezoid for joining the petals together. Also, in the smaller base of the trapezoid, a rectangular strip of about 15-20 mm should be left, and in the center of the square, cut another one with a side 20-25 mm smaller.

When the pattern is ready, sand the edges, bend the body and join the seams with rivets. Prime the inner surface, open with white spray paint without gloss and leave to dry for 2-3 days. From the front side of the case, diagonally cut a square piece of glass of suitable size and lean it against the curved shelves from the inside. Walk liberally along the contour of the glass with white silicone, and coat the seams of the body with it.

Fasten the mounting panel or board with eight 4 mm bolts, having previously drilled holes along the edges of each shelf on the narrow side of the case. To make the plate fit tightly, use a PVC foam door seal. It will not be easy to tighten the bolts, their heads are not accessible, so use a couple of lock nuts on the end.

Installation of radio elements

If you chose LEDs with pin leads, you will need a textolite plate for their installation. Think over the layout and draw the current-carrying paths with a permanent marker. The anodes of all LEDs (long tails) can be assembled on one "ground" bus. The cathodes are also collected at one point, but a current-limiting resistor should be connected in series to the power circuit of each LED.

Its calculation is simple: subtract the LED voltage from the supply voltage and divide by the maximum allowable current. To be safe in case of fluctuations in the source voltage, the allowable LED current can be deliberately lowered to 90-95% of the passport value.

An example of a LED matrix circuit of diodes with an operating voltage of 3 volts and an operating current of 20 mA

The approximate supply voltage for one LED is 4 V. If the source produces more, it is advisable to turn on the diodes in a mixed circuit, where garlands are connected in parallel, each of which has one LED for every 4-5 V of voltage. The allowable current for such a series assembly is determined as the sum of the allowable currents of each, and the forward voltage remains the same, provided that this parameter is the same for each LED.

After placing the elements and drawing the tracks, etch the textolite plate in a solution of citric acid (30-50 g), 3% hydrogen peroxide (100 ml) and table salt (2 teaspoons), periodically checking the degree of dissolution of unprotected areas. Drill holes for the pins with a 1.5-2 mm drill, drill eight holes for attaching the board to the case, and then carefully lubricate the live parts with rosin solder.

You can also use a circuit board for the LED matrix

If you are assembling diodes or matrices on a cooling substrate, they are mounted in a hinged way. As the mounting plate, you should choose an aluminum radiator of the "comb" type. Each LED is attached using two or three holes, mark them all at once and drill from the back of the radiator with a 2.5 mm drill.

For fastening, use short self-tapping screws 3.5x11 mm for metal profiles, but without a drill at the end. Before fixing the diode, apply a small amount of KPT-8 thermal paste to the substrate.

The cathode (-) and anode (+) of LEDs with a substrate are marked, the connection diagram and the calculation of protective resistors are the same for all types. Connect the elements to each other by means of a piece of telephone wire. In order not to do unnecessary work, the anodes can be immediately soldered with short jumpers to the aluminum radiator case.

Question about the power supply

After assembling the LEDs, you will be left with two outputs, which would be nice to apply voltage, but where to get it from? Household power supplies are of little use here; to power LEDs, you need an LED driver that produces a pulsating constant current of a stable value.

For most products, a driver for interior lighting systems or for LED strips is suitable. It is better to purchase a power supply in advance in order to calculate the number and connection scheme of diodes according to the output voltage and the total stabilization current.

For small crafts, you can use general-purpose power supplies with an output ripple current of 0.5-1.5 A and a voltage of 3-5 V higher than the forward voltage of the diodes. You can stabilize the power supply with the LM317 chip, for more powerful spotlights, use the LM350 and LM338, respectively, increasing the power of the source.

The current limit of the microcircuit can be adjusted by changing the resistance of the resistor. Its value is defined as 1.25 / I, where I is the current of the LED or assembly.

The LED spotlight will provide a powerful source of light with low power consumption. At the same time, you can take into account your own needs - make a shock-resistant case or a portable structure. As a basis, you can take an old lighting fixture, an aluminum profile or a plastic frame. A do-it-yourself LED spotlight can be made from spare parts from old computers, and LED lamps are sold in electrical stores.

Design features of the spotlight

You can take an old halogen or LED spotlight and upgrade it with an improved light source and reflector. If this is not available, you can buy a cheap street lamp, you only need to replace some elements.

If the task is to make a lantern for your own needs and preferences, you will have to think through the entire design yourself. This is an option for experienced craftsmen who have assembled more than one electrical appliance with their own hands. In this case, you need to select a light source and a current source. It is better to provide cooling so that the device does not overheat.

Spotlights that are constantly operated outdoors must be protected from moisture. Glass and all joints of the body must be well sealed. It is recommended to hang a visor above the lantern to protect it from rain.

Required materials and parts

The necessary parts for assembling an LED spotlight can be taken from an old computer or laptop. If there is no suitable case, you can assemble it yourself from a metal profile.

Housing material

Cheap flashlights are made with a plastic case. Their advantage is low weight and low cost. But plastic loses to metal in durability, it cannot be used all year round. If you plan to hang a spotlight over the entrance to a garage or house, it is better to make a metal case. Depending on the operating conditions, a carrying handle and shock protection can be provided.

The main thing in the case is the holes at the top and bottom for ventilation.. LEDs heat up from long operation, they need to be effectively cooled. Through the upper holes, air enters, blows all the details and takes heat from them. Fans blow out the exhaust air through the lower openings. This projector design is not suitable for the street.

Sources of light

The main advantage of LED-lamps is their longevity. They last 50,000 hours, 10 times longer than halogen lights. With a proper arrangement of reflectors, the brightness of the LEDs in the spotlight will be much higher than that of other lamps.

If you need a bright light source, it is better to take a few small LEDs of 1 or 3 watts. For a medium-sized device, you will need 20 pieces. The street lamp must have a power of at least 30 watts.

Source of power

Do-it-yourself LED spotlight can be made at 12 or 220 volts. You can find a power supply at a computer parts store. For example, for a spotlight with 20 1 W LEDs, a 19 V laptop power supply is suitable. It is better to buy current sources in a moisture-resistant case right away, then you won’t need to come up with your own protection.

Assembly process

To make an LED spotlight, you need to prepare:

• soldering iron;
• hot glue;
• sealant;
• power wires;
• reflector.

To amplify the light, use a ready-made reflector or mirror tape.

Assembling the spotlight

Separate LEDs must be assembled into a circuit immediately on the radiator. A cooler from a computer, laptop or server will do. Diodes are attached with hot glue and connected by tracks or wires. After that, connect the power source, check the operation of the bulbs and the fan. It is important to make sure that the radiator maintains a constant temperature, for this you can use an infrared gun.

The body of the spotlight can be assembled from an old lantern, a bracket and an aluminum pipe. In the lantern you need to make a hole at the bottom for the fans. An aluminum pipe will work as a base, and an old bracket can be used as a carrying handle.

We connect to the network

After completing all the work, you need to connect the spotlight to the network and check it. It is better to do this on the street in complete darkness in front of the wall. From a great distance, you need to evaluate the spot of light that the lamp gives. In the future, the device can be improved by adding a portable battery and a USB connector for charging. The convenient handle with a hook will allow you to take the lantern on hikes and fishing trips.

LED spotlights are very popular these days. But, like any electronics, spotlights break relatively often.

Do-it-yourself LED spotlight repair and today's article will be devoted.

The whole theory on the construction of LED spotlights and terminology, and here is a practice for home craftsmen.

The spotlight does not light up - where to start?

First of all, you need to make sure that 220 V power is supplied to the driver. This is Az. Then it remains to decide what is faulty - the LED driver or the LED matrix.

Checking the driver

I remind you that the word “driver” is a marketing ploy to refer to a current source designed for a specific matrix with a certain current and power.

In order to test the driver without an LED (idle, no load), just apply 220V to its input. A constant voltage should appear at the output, slightly larger in value than the upper limit indicated on the block.

For example, if the range of 28-38 V is indicated on the driver block, then when it is turned on idle, the output voltage will be approximately 40V. This is explained by the principle of operation of the circuit - to maintain the current in a given range of ± 5%, with an increase in load resistance (idle = infinity), the voltage must also increase. Naturally, not to infinity, but to some upper limit.

However, this method of verification does not allow us to judge the health of the LED driver by 100%.

Subscribe! It will be interesting.

The fact is that there are serviceable blocks that, when turned on idly, without load, either will not start at all, or will give out something incomprehensible.

I suggest connecting a load resistor to the output of the LED driver to provide it with the desired mode of operation. How to choose a resistor - according to Uncle Ohm's law, looking at what is written on the driver.

LED - 20W driver. Stable output current 600 mA, voltage 23-35 V.

For example, if Output 23-35 VDC 600 mA is written, then the resistance of the resistor will be from 23/0.6=38 ohms to 35/0.6=58 ohms. Choose from a range of resistances: 39, 43, 47, 51, 56 ohms. Power must be appropriate. But if you take 5 W, then it will be enough for a few seconds to check.

Attention! The output of the driver, as a rule, is galvanically isolated from the 220V network. However, you should be careful - there may not be a transformer in cheap circuits!

If, when the required resistor is connected, the output voltage is within the specified limits, we conclude that the LED driver is working.

Checking the LED Matrix

For testing, you can use a laboratory power supply,. We supply a voltage that is obviously less than the nominal value. We control the current. The LED matrix should light up.

What to do if the power of the LED module is unknown

There are situations when there is an LED chip, but its power, current and voltage are unknown. Accordingly, it is difficult to buy it, and if it is serviceable, then it is not clear how to choose an adapter.

This was a big problem for me until I figured it out. I am sharing with you how to determine by the appearance of the LED assembly what voltage, power and current it is.

For example, we have a spotlight with the following LED assembly:

9 diodes. 10 W, 300 mA. Actually - 9 W, but this is within the margin of error.

Gave in the fact that in the LED matrix spotlights diodes with a power of 1 W are used. The current of such diodes is 300 ... 330 mA. Naturally, all this is approximately, within the margin of error, but in practice it works exactly.

In this matrix, 9 diodes are connected in series, they have one current (300 mA), and a voltage of 3 Volts. As a result, the total voltage is 3x9 \u003d 27 Volts. Such matrices require a driver with a current of 300 mA, a voltage of approximately 27V (usually from 20 to 36V). The power of one such diode, as I said, is about 9 watts, but for marketing purposes this spotlight will be rated at 10 watts.

The 10W example is a bit atypical due to the special arrangement of the LEDs.

And what's fresh in the VK group SamElectric.ru ?

Subscribe and read the article further:

Another example, more typical:

You already guessed that two horizontal rows of dots of 10 pcs are LEDs. One strip is offhand 30 volts, current 300 mA. Two strips connected in parallel - voltage 30 V, current twice as much, 600 mA.

A couple more examples:

Total - 50 W, current 300x5 \u003d 1500 mA.

Total - 70 W, 300x7 \u003d 2100 mA.

I think there is no point in continuing, everything is already clear.

A slightly different matter with LED modules based on discrete diodes. According to my calculations, there is one diode, as a rule, has a power of 0.5 watts. Here is an example of a GT50390 array installed in a 50W spotlight:

LED spotlight Navigator, 50 watts. LED module GT50390 - 90 discrete diodes

If, according to my assumptions, the power of such diodes is 0.5 W, then the power of the entire module should be 45 W. Its circuit will be the same, 9 lines of 10 diodes with a total voltage of about 30 V. The operating current of one diode is 150 ... 170 mA, the total current of the module is 1350 ... 1500.

Who has other considerations on this subject - you are welcome in the comments!

LED spotlight driver repair

It is better to start repair by looking for the electrical circuit of the Led driver.

As a rule, LED spotlight drivers are built on a specialized MT7930 chip. In the article about the Spotlight Device, I gave a photo of the board (non-waterproof) based on this microcircuit, once again:

LED spotlight Navigator, 50 watts. Driver. GT503F board

Attention! Information on driver circuits and a little more on repair!

LED replacement

When replacing the LED matrix, there are no special tricks, but you need to pay attention to the following things.

• carefully remove the old thermal paste,
• Apply heat conductive paste to the new LED. It is best to do this with a plastic card,
• fix the diode evenly, without distortions,
• remove excess paste
• do not reverse the polarity,
• do not overheat when soldering.

When repairing an LED module consisting of discrete diodes, first of all, you need to pay attention to the integrity of the soldering. And then check each diode by applying a voltage of 2.3 - 2.8 V to it.

Where to get repair parts

If you need a quick repair, then it is best, of course, to run to the store across the street.

But if you are doing repairs on an ongoing basis, then it is better to look where it is cheaper. I recommend doing this on the well-known website Aliexpress.

I end with this. I encourage colleagues to share their experience and ask questions!

The assembly of LED lamps from improvised means is gaining more and more popularity. This is due not only to the fact that home electricians are trying to develop their skills, but also to the poor quality of manufactured Chinese products. This article will discuss how to make a spotlight with your own hands at home. For readers of the site, we have prepared several interesting assembly options.

Step 1 - Choose a Case

The easiest way is to assemble the LED spotlight yourself from the Chinese halogen model. This is due to the fact that it will not be necessary to invent a case and a reflector. Having spent 200 rubles on the purchase of a low-quality street lamp, you will only have to replace the lamp with an LED one. This will allow you to enjoy the bright glow of an economical and durable spotlight.

By the way, you can look for a separate case in a specialized store. Perhaps the cost of the product will be even lower than that of a halogen lamp.

If you decide to make a powerful LED spotlight yourself, which will also get very hot, we recommend that you additionally take care of heat dissipation. To do this, you can either find an aluminum radiator and fix it, or make a completely aluminum box, as in the photo below.

Step 2 - Choosing a Lamp

As for the lamp for a homemade LED spotlight, the easiest way is to buy it. Power for must be at least 30 watts. However, a separate purchase of a case and LED bulbs may not come out very cheap. That is why we recommend making a lamp with your own hands. The advantage is that you can build a light bulb powered by 220 or 12 volts. In the first case, this will allow you to connect the lamp directly to the network. About what we talked about, we advise you to read it. If you wish, you can also make a light bulb from an old energy-saving one, from individual LEDs, or even from a single-color LED strip, as in the photo below.

We draw your attention to the fact that we also provided all the diagrams and video assembly instructions in the above article!

If you still decide to make a spotlight with your own hands from a halogen one, you will have to additionally find the base of the LED light bulb.

Step 3 - Assembling the Spotlight

After all the elements are assembled, you can easily assemble a homemade product without much effort. All you need to prepare is a sealant. For a more understandable development of the information, we provide you with step-by-step assembly instructions:

This is how you can make a spotlight with your own hands at home. We recommend that you additionally equip the homemade product with a motion sensor and a photo relay, which will save energy even more and make the lighting automatic.
