How to assemble an LED lamp. How to make a simple DIY LED lamp

According to statistics, it was found that the cost of LED lamps has dropped significantly. Such indicators led to an increase in the purchase of highly economical lighting equipment for private houses and apartments. Those who are excellent with a soldering iron will not need to go to the store at all in order to equip their home, as you can create a lamp with your own hands, without resorting to factory products. Thus, you can save a large amount of money and choose the design of the device that will fit the interior of the apartment.

Scheme of the LED lamp.

LEDs have their own peculiarity, which consists in a constant current mode and a low degree of voltage. Therefore, for the implementation of the lighting process, devices such as power supplies are mainly used. Some solder on their own electrical circuits on boards, which is not so easy, especially for those who are not familiar with this field of activity.

Creating a lamp with your own hands, a lamp or any other lighting fixture, you need to take into account the fact that one third of such a unit as rated power will go to the conversion luminous flux, the remaining parts are needed for heat loss.

It is important to remember that overheating of the LEDs may shorten their life. When assembling any design of LEDs on your own, heat must be removed from the entire structure during power supply.

What LEDs should you use?

Table of types of LEDs.

Initially, it is advisable to choose the specific type of LEDs that you need. If we consider powerful and low-power ones, then the first type is much more profitable, due to the fact that the labor intensity is higher. The ratio of low-power to high-power is 20:1. According to such indicators, we can conclude that with low-power LEDs there is much more soldering. Among the powerful LEDs, there are a couple of varieties, some of which are designed for output installation work, while others are for surface. In most cases, output is used, since with them installation work carried out much faster.

Power supplies

For the durability of LEDs, an excellent driver is needed, and in another way it can be called a power source. The driver can be packaged or unpackaged, with or without galvanic isolation. If we consider exactly the alteration of lamps, then it is desirable to use the type of unpackaged driver, in which there is galvanic isolation.

The caseless view is very useful in that it is compact in size and also has a lower degree of heating. But there are certain disadvantages, which are manifested in the difficulty of fastening.

The use of galvanic isolation is generally required for safety reasons, as this can avoid electric shock. In the absence of such technology, some receive minimal electrical shocks.

The electrical circuit of the LED lamp.

When choosing drivers, it is advisable to pay attention to the indication of the minimum and maximum number of LEDs that can be connected to the connection. If such data is not available, then it is worth looking at the output voltage indicators of the power supply.

The power supply can be of two types, one of which consists of an electromagnetic interference filter, and the second, respectively, does not have it. Devices that do not have filters are more likely to interfere electromagnetic waves and conducting frequencies to receivers.

Using a heatsink for LEDs

In order to use the LED successfully and for a long time, it is worth using heat sinks, as they are as important components of the process as power supplies. The radiator must be made exclusively of aluminum. Finding such material is very simple, since each person has old crockery from aluminium. In order to be able to dissipate heat from the LED, it is the size of the area that must be taken into account, and not the thickness. It is worth noting that on computer coolers fans are installed, since without such a device, heat from the LED will be removed at a minimum speed.

The process of making a lamp with your own hands

Before you start developing a lamp yourself, it is advisable to prepare everything necessary tools. In particular, it is desirable to have:

Diagram of the lamp body.

• basic and spare LEDs;
• microtransformer;
• multimeter;
• red LED lights;
• 100 ohm resistor;
• a 400 uF and 10 uF capacitor;
• cartridge;
• degreaser;
• soldering iron;
• mounting adhesive;
• board;
• lampshade.

Initially, it is advisable to check each LED that will be included in the circuit, and the quality of the supply voltage in the network cable. To carry out such a process, it is worth using a microtransformer. Thus, when setting up and during a test check of a future lighting device, the adjustment will be much smoother.

In order to measure, the voltage drops when DC and the effect on the resistor or not, and a multimeter is used to accurately calculate the current of the diodes. As a rule, when self assembly try to use six-volt lamps, but often you may need those that are designed for 12 volts.

The diodes themselves must be High Quality so that an unpleasant bluish glow can be avoided, which will not only ruin appearance lamp, but also hurt the eyes.

Scheme of connecting LED parts to the lamp housing.

The assembly scheme can be called very simple and without loss for the driver. The only drawback is the lack of insulation on the wires, that is, the LED lamp itself can be subject to current shocks. Focusing on the latest data, it should be borne in mind that it is desirable to protect the lamp from falling, but later the circuit can be upgraded.

1. Resistors are needed to protect the board when connected to the network in order to avoid a voltage surge. In its absence, the use of a tiny rectifier bridge is desirable.
2. The use of a 400 uF capacitor is required in order to set the energy at the right level, which is required for transmission and additional addition of lamps, with free bandwidth. Before work, it is advisable to make sure that it is the type of rated voltage that is being used, which, as a rule, is half the usual current in the network.
3. The use of a 10 uF capacitor is necessary to create an ideal light source, as well as to eliminate effects such as glare and flashing. The height of the rated voltage in this case should be twice as high as the previous capacitor.

If it is not possible to purchase a new cartridge, it can be removed from the old lamp. To do this, you need to carefully break the light bulb, and so that the socket part of the cartridge is not damaged. After such a procedure, the cartridge itself should be protected and treated with a degreaser. It is important that before installation, the hole in the cartridge is checked again for the presence of lamp residues that can harm the future lighting system, and it is advisable to carry out additional processing with acetone or alcohol.

Mounting the cartridge to the resistor and transistor

Next up is the soldering work. Using a soldering iron, a tiny rectifier is installed, and the materials must be prepared in advance and be at hand. The surface is processed in a mandatory mode, and the actions themselves must be as accurate and accurate as possible in order to prevent damage to already installed parts.

In order to carry out heat shrinkage, any type of mounting adhesive is used, since the material must be intended for such actions, and in no case for clerical purposes.

Installation of LED lamps is considered the most important and interesting point in the entire assembly of the lamp. The basis will be a board purchased in advance or prepared from old appliances. If it belonged to old structures, then, accordingly, the board should be cleaned of parts and various burrs.

When conducting and connecting each contact, they should be checked and cleaned if the signal is not received. There is very little left - and the lamp will be able to please its creator. In order to complete the work, you simply need to collect all the details that are available. To be more precise, each part is soldered to the tablet and to the resistor device. Next, everything is isolated with glue, the connections between the diodes are checked for proper light propagation.

As elements of lighting devices, LEDs appeared on the market relatively recently. The first LEDs were created in 1962, they emitted a faint red light. For lighting, such devices were not used due to the fact that a very narrow spectrum of light was emitted, and the price for them was quite high.

LED home lighting

With the development of LED manufacturing technology, other colors of the visible spectrum of radiation appeared, the cost of production decreased, and the range of application of light-emitting devices expanded. But still they were still far from economical lighting systems. They were mainly used for indication in electrical and radio devices. positive qualities were low power consumption and durability.

LEDs different color and forms

Advantages of LED lighting

Lighting with LED panels has become widely used with the appearance of LEDs with an efficiency of more than 50%, while an incandescent lamp produces 3.5-4% efficiency. Benefitsa uhthat lighting system:

• low power consumption;
• environmental friendliness;
• service life of about 30,000 hours;
• reliability;
• unlimited number of on-off;
• high light output;
• wide operating range of ambient temperature;
• small geometric dimensions;
• the possibility of obtaining the desired radiation spectrum (red, yellow, green, white);
• the ability to regulate the strength of the light flux;
• low operating temperature.

There are many positive qualities, and they give an advantage over traditional incandescent lamps and an energy-saving fluorescent lamp.

LED lamp

How to make an LED lamp? It can be made from individual LEDs. To do this, you need piece emitting diodes. Connecting in series required amount, you can get the given power.

To protect against failure of the elements, the installation of a resistor is required, which will limit the current in the semiconductor circuit.

Regardless of the supply voltage of such a lamp, 220 V or 12 V from the car, the resistor is calculated so that the operating current does not exceed the passport values ​​​​of the diode. After assembly and verification, you can embed the structure in the base of a conventional incandescent light bulb. A home-made LED lamp is no worse than a factory one, it even has an advantage - it is easy to fix it in case of failure to work, which cannot be said about factory products.

LED lights

Lamps in which the active element is an LED are called LED lamps. You can use an existing chandelier by inserting a semiconductor lamp into it, or you can make a do-it-yourself diode lampto use it to light your home. If you have the skills, you can make a lamp from an LED strip using the developed circuit diagrams .

LED strip for making a lamp

The tape is a set of LEDs, connected together properly in the factory. It can be cut in sections and connected in parallel and series circuits. A current limiting resistor is built into the circuit. The supply voltage is usually used 12, 24, 36 and 220 V.

By combining the number of sections, you can get the required illumination and power consumption. To connect to a 220 V network, you can assemble a voltage reduction circuit if you plan to use it to light a car ( for voltage 12V). When using a strip of LEDs for a voltage of 12V, special drivers are used, or it is worth spending time on making a home-made power supply device.

DIY lamp

You can design a ceiling, wall, floor or table lamp according to your taste and existing interior. You can use any improvised materials: from balloons to iron structures.

It is necessary to determine the type of LEDs used or the finished tape. If these are diodes - calculate right amount if the tape is the desired length.

These data will be needed to calculate the power consumption of the lamp.

LEDs are connected in series in 3-4 pieces, depending on the operating voltage of the diode, and a limiting resistor is placed in series with them to prevent the diode from burning out when the rated current is exceeded. If it is necessary to increase the luminous flux, another 2-3 such blocks are installed in parallel. This can be done and table lamp, and a lamp for the car.

The power consumption is known. One option is to purchase a driver. Its parameters should correspond to the consumption parameters of the luminaire or be slightly larger.

If the consumption parameters are greater than the driver parameters, it will fail and, quite likely, the LED structure itself will fail.

12 V power supply circuit

Transformer T1 with parameters: input voltage 220 V, output - 9-12 V. You can use a ready-made transformer from an old TV. The next element is the diode bridge D1-D4. In the presence of a free diode bridge from charger car, you can use it. The voltage for which the diodes are designed to operate must be above 12 V, and the rectification current must be greater than the current consumption of the LED lamp.

Element A1 - any voltage stabilizer with an operating current exceeding the current consumption of the lamp, and an output voltage of 12 V. All elements of the circuit are available at any radio parts store. You can assemble and solder the circuit using a soldering iron, fixing all the details in plastic case. Printed wiring here will be redundant, a hinged one is suitable in compliance with the rules of high-quality soldering.

The voltage of the input circuit is 220 V dangerous to human life. When working, you must follow the safety regulations.

After the installation is completed, you need to fix all the parts in the case and bring out two wires for connecting the input voltage and two for 12V. Be sure to mark the input wires with "+" and "-" outputs to prevent polarity reversal. From practice: the red wire means plus, the blue one means minus.

A do-it-yourself diode lamp for the home is made, it pleases the eye and saves energy.

Car lamp

The voltage of the car battery is 12 V. When the car is running at high speeds, the generator generates more voltage - 14-14.5 V. This is necessary to charge the car battery. This information is important to consider in order to assemble an energy-saving lamp for a car.

Car underbody lighting LED strip

If used for this led strip, then no additional scheme do not need to be applied. Take a 12V tape, cut it off required size and, observing the polarity, connect it to the car's network instead of a regular light bulb.

The use of decorative homemade lamps

Homemade lamps perfectly perform the role of decorative lighting. They are rarely used for general lighting. For the manufacture of materials used poorly transmitting light, and light sources are limited in size or power. To avoid damage to the structure, it is recommended to use low-heating LED lamps or strips as a light source, which, unlike incandescent lamps, do not pose a fire hazard.

Homemade lamps as the main lighting

As the main lighting, homemade lamps are increasingly used due to technological, powerful and safe light sources.

If you are wondering how to make a DIY LED lamp at home, then we will provide a few step by step instructions with photo and video examples that will allow you to assemble an LED light bulb in no more than an hour. All ideas provided below will be listed from easiest to hardest, allowing you to choose suitable option depending on the skills of handling a soldering iron and electrical circuits.

Idea number 1 - Upgrading the halogen light bulb

The easiest way is to make an LED lamp yourself from a burned-out halogen bulb with - GU4. In this case, you will need the following materials and tools:

• LEDs. Select their number yourself, depending on how bright it should be. LED lightening. We immediately draw your attention to the fact that you should not choose more than 22 diodes (this will complicate the assembly process and also make the light bulb too bright).
• Super glue (ordinary glue is also suitable, but it will harden longer, which will not allow you to make an LED lamp quickly).
• small piece copper wire.
• Resistors. Their number and power will be calculated by an online calculator.
• A small piece of sheet aluminum ( Alternative option- an ordinary can of beer or carbonated drink).
• Internet access. You will need to open a special online calculator to calculate the circuit of the LED lamp.
• Hammer, soldering iron and hole punch.

Having prepared all the materials, you can proceed directly to the assembly of the diode light bulb. We will provide instructions for creating a home-made one step by step, with photo examples of each stage, so that you can clearly see the installation process.

So, to make a 12 volt LED lamp, you need to follow these steps:

1. Remove the top glass from the old halogen bulb, as well as the white putty near the pin base (as shown in the photo below). For this, it is best to use a screwdriver.
   
2. Turn the lamp socle upside down and carefully use a hammer to knock out the pins from the seat. The old halogen bulb should fall out.
   
3. According to the number of LEDs you have chosen, come up with a diagram of their location, on the basis of which make a paper stencil. You can use an existing blank and print one of the ready-made diagrams that are provided in the picture:
4. Glue the stencil to the aluminum sheet with super glue, cut the sheet to the shape of the stencil, and then punch seats under the LEDs.
   
5. Generate an assembly drawing of an LED lamp on the Internet for your conditions. In our case, to create an LED light bulb at home from 22 diodes, you need to assemble the following circuit:
   
6. Put the aluminum disk on convenient stand and insert the LEDs into the seats, as shown in the photo. To simplify the soldering process, bend the cathode leg of one diode to the anode leg of the other.
   
7. Carefully glue all the LEDs, making them a single design. Important point– glue should not get on the legs of the diodes, because. when soldering, extremely unpleasant smoke will be emitted.
   
8. When the glue hardens, start soldering the legs. By the way, we recommend that you do this, which also does not take much time. According to the diagram, solder the diodes of the LED lamp, leaving only one plus leg and one minus leg for power connection. It is recommended to cut the "-" leg in half, so as not to confuse the polarity of the contacts of a home-made LED light bulb in the future.
   
   
9. Solder the resistors to the negative terminals according to the diagram. As a result, according to our example, you should get 6 positive terminals and 6 negative ones (with resistors).
   
10. Solder the resistors according to the generated schematic.
    
11. Solder the same piece of copper wire to the two contacts formed, which will make it possible to make the pin base of the LED lamp at home. By analogy with the previous advice, make one leg shorter (minus) for a while, so that later you don’t confuse anything and make the connection correctly.
    
    
12. To prevent this from happening in the future, carefully glue the space between the legs that are brought out.
    
13. Perform the final assembly of the LED light bulb: place the disk on the reflector and carefully glue it.
    
14. With a marker, sign on the body of the assembled LED lamp where “+” and where “-”, also indicate that the home-made light source is designed to be connected to a 12 volt power supply, not 220.
    
    
15. Check the assembled homemade product. To do this, connect led light bulb to a car battery or a 220/12 Volt power supply.
    

Like this in a simple way you can make an LED lamp with your own hands from improvised means. As you can see, there is nothing difficult and it will not take much time to assemble! We recommend checking out a few best ideas on how to create a light bulb at home, which we provided in the video gallery:

Idea number 2 - "Housekeeper" in progress!

Second, no less interesting idea- assemble a light bulb energy saving lamp. There are also no particularly serious works and even a not very experienced electrician can handle the assembly.
To begin with, you must prepare the following materials and tools for assembling an LED lamp with your own hands:

Having prepared all the materials, you can proceed to the assembly. This instruction is more creative, so if you decide to make a diode light bulb from a burnt housekeeper, carefully look at the photo examples.

Stages of work:

According to this instruction, you can easily make an LED lamp from a fluorescent or halogen light bulb!

Idea number 3 - LED strip for the base

If you are not so good with a soldering iron and at the same time have no idea how to assemble a circuit on fiberglass, it is better to make an LED lamp with your own hands from LED tape. In this case, instead of a driver, you can use a power supply that converts 220 Volts in the network to 12. The only significant drawback this method- large dimensions of the power supply, so this option is recommended if you decide to make LED lighting in the room with spotlights. You can try to collect all the bulbs for them with your own hands and connect them to a single power supply, which will hide without problems in the ceiling.

So, all you have to do is:

That's the whole instruction for assembling an LED lamp from a tape. As you can see, everything is much easier than even making a light bulb according to the generated scheme. On this our simple instructions end, and now you know how to make an LED lamp with your own hands from an energy-saving light bulb, a diode tape and a halogen light source! We hope that the ideas provided were useful and understandable for you!

LED lamps are widely used in the organization of household, street, industrial lighting. Their important advantages are economy, environmental friendliness, unpretentiousness in service.

A handmade LED lamp will definitely find its application in your home. Detailed instructions for manufacturing, as well as assembly diagrams, you will find in the presented article.

The basis of the LED lamp is a single-sided semiconductor, the size of which is several millimeters. There is a unidirectional movement of electrons in it, which allows you to convert alternating current into permanent.

An LED crystal consisting of several layers is characterized by two types of electrical conductivity: positively and negatively charged particles.

The side containing the minimum number of electrons is called the hole (p-type), while the other with big amount these particles is called electronic (n-type).

When elements collide at a p-n junction, they collide, generating photons of light particles. If at this time to maintain the system at a constant voltage, the LED will emit a stable stream of light. This effect is used in all designs of LED lamps.

Four types of LED devices

Depending on the placement of LEDs, such models can be divided into the following categories:

1. DIP. The crystal is arranged with two conductors, above which is the magnifier. Modification received wide use in the manufacture of signs and garlands.
2. "Piranha". Devices are assembled similarly to the previous version, but provide four outputs. Reliable and durable structures most often used to equip cars.
3. smd. The crystal is placed on top, which greatly improves heat dissipation, and also helps to reduce the size of devices.
4. OWL. In this case, the LED is soldered directly into the board, which increases the intensity of the glow and protects against overheating.

A significant drawback of COB devices is the inability to replace individual elements, which is why you have to buy new mechanism due to a single failed chip.

Chandeliers and other household lighting fixtures usually adopt the SMD design.

LED lamp device

The LED lamp consists of the following six parts:

• Light-emitting diode;
• plinth;
• driver;
• diffuser;
• radiator.

The operating element of such a device is an LED that generates a stream of light waves.

LED devices can be designed for different voltages. Most in demand small items 12-15W and larger 50W fixtures

Plinth, which can have different kind and size, it is also used for other types of lamps - fluorescent, halogen, incandescent. At the same time, some LED devices, such as LED strips, can do without this part.

An important element of the design is the driver, which converts the mains voltage into a thrust on which the crystal operates.

This node largely depends on effective work lamps, in addition, high-quality, having good galvanic isolation, provides a bright constant light output without a hint of blinking.

A conventional LED produces a directional beam of light. To change the angle of its distribution and provide high-quality lighting, a diffuser is used. Another function of this component is to protect the circuit from mechanical and natural influences.

The radiator is designed to remove heat, excess of which can damage the device. Reliable heatsink performance optimizes lamp performance and extends lamp life.

The smaller this detail, the more heat load you will have to withstand the LED, which will affect the speed of its burnout.

Advantages and disadvantages of a homemade lamp

Specialty stores offer big choice LED devices. However, sometimes in the assortment it is impossible to find a device that meets the necessary parameters. In addition, LED-devices traditionally have a high cost.

The disadvantages of the products include the lack of a guarantee from the manufacturer. In addition, if carelessly assembled, such devices may have an unattractive appearance.

Meanwhile, it is quite possible to save money and get the perfect lamp by doing the assembly yourself. This is easy to do, and it will be enough elementary technical knowledge and practical skills.

A self-made LED device has a number of significant advantages over an analogue purchased in a store. They are economical: with careful assembly and the use of quality parts, the service life reaches 100 thousand hours.

Such devices show a high degree of energy efficiency, which is determined by the ratio of power consumption and the brightness of the generated light. Finally, their cost is an order of magnitude lower than factory counterparts.

Do-It-Yourself Problems

The main issues that have to be addressed in the manufacture of LED lamps are the conversion of alternating electric current into pulsating and its alignment to constant. In addition, it is necessary to limit the strength of the electric current to 12 volts, which is necessary to power the diode.

To independently create a lamp on LEDs, you can use parts purchased in specialized stores, or elements from burnt out appliances

Thinking through the device, you should also solve a number of design problems, namely:

• how to arrange the circuit and LEDs;
• how to isolate the system;
• how to ensure heat exchange in the device.

Before assembly, it is advisable to think through all these problems, taking into account the requirements that apply to a homemade light source.

Schemes of LED lamps

First of all, you should develop an assembly option. There are two main methods, each with its own pros and cons. Below we will consider them in more detail.

Variant with diode bridge

The circuit includes four diodes that are connected in different directions. Thanks to this, the bridge acquires the ability to transform the mains current of 220 V into a pulsating one.

This happens as follows: when sinusoidal half-waves pass through two diodes, they change, which causes a loss of polarity.

When assembling, a capacitor is connected to the positive output in front of the bridge; in front of the negative terminal - a resistance of 100 ohms. Another capacitor is installed behind the bridge: it will be needed to smooth out voltage drops.

LED element manufacturing

The easiest way to create an LED lamp is to make a light source based on a broken lamp. It is necessary to check the operability of the detected parts, which can be done using a 12 V battery.

Defective elements must be replaced. To do this, unsolder the contacts, removing the burned-out elements, put new ones in their place. It is important to observe the alternation of anodes and cathodes, which are mounted in series.

If you need to change only 2-3 pieces of the chip, you just need to solder them to the areas where the failed components were previously located.

With complete self-assembly, you need to connect 10 diodes in a row, observing the rules of polarity. Several completed circuits are soldered to the wires.

In the manufacture of the lamp, you can use boards with LEDs, which can be found in burnt out devices. It is only important to check their performance

When assembling circuits, it is important to ensure that the soldered ends do not touch each other, as this can lead to a short circuit of the device and failure of the system.

Fixtures for softer light

To avoid the flickering characteristic of LED lamps, the scheme described above can be supplemented with several details. Thus, it should consist of a diode bridge, 100 and 230 ohm resistors, 400 nF and 10 uF capacitors.

To protect the device from voltage drops, a 100 ohm resistor is placed at the beginning of the circuit, followed by a 400 nF capacitor, after which a diode bridge is installed and another 230 ohm resistor, followed by the assembled LED chain.

Resistor devices

A similar scheme is also quite accessible to a novice master. It requires two 12k resistors and two chains of the same number LEDs that are soldered in series with respect to polarity. In this case, one strip on the side of R1 is connected to the cathode, and the other - to R2 - to the anode.

The lamps made according to this scheme have a softer light, since the active elements are lit in turn, due to which the pulsation of the flashes is almost imperceptible to the naked eye.

Materials for making homemade

In addition to the body, other elements will be required to create the lamp. These are, first of all, LEDs, which can be purchased in the form of LED strips or individual HK6 elements. The current strength of each part is 100-120 mA; voltage 3-3.3 V.

The assembly of some circuits involves the use of additional links, for example, a driver, so the set of components for each specific case is considered separately.

Rectifier diodes 1N4007 or a diode bridge are also required, as well as fuses, which can be found in the base of the old device.

You will also need a capacitor, the capacitance and voltage of which must correspond to the electrical circuit used and the number of LED elements used in it.

If you are not using a ready-made board, you need to think about the frame to which the LEDs are attached. For its manufacture, a heat-resistant material that is not metal and non-conductive is suitable. electricity.

As a rule, such a part is made of durable plastics or thick cardboard. To attach the LED elements to the frame, you will need liquid nails or superglue.

Assembling a simple LED lamp

Consider the implementation of the lamp in a standard base from fluorescent lamp. To do this, we will have to slightly modify the above list of materials.

In this case we use:

• old base E27;
• NK6 LEDs;
• RLD2-1 driver;
• a piece of plastic or thick cardboard;
• Super glue;
• electrical wiring;
• soldering iron, pliers, scissors.

Initially, you need to disassemble the lamp. For luminescent devices, the connection of the base to the plate with tubes is carried out using latches. It is important to locate the fastener and pry the elements with a screwdriver, which will make it easy to detach the cartridge.

The process of assembling a homemade LED lamp is simple. A driver is inserted into the case from the old device, on top of which a board with LEDs is installed

When disassembling the device, extreme care must be taken so as not to harm the tubes inside which there is a toxic substance. At the same time, it is necessary to monitor the integrity of the electrical wiring connected to the base, as well as to save the parts contained in it.

top with gas discharge tubes connected, we use to make the plate needed to connect the LEDs. It is enough to remove the tubular elements, and fix the LED parts in the remaining round holes.

For their secure fastening, it is better to make an additional plastic or cardboard cover, which will serve to isolate the chips.

The lamp will use NK6 LEDs, each of which consists of 6 crystals with parallel connection. They allow you to create a fairly bright lighting fixture with a minimum of electricity consumed.

To connect each LED to the cover, two holes must be made. They should be pierced carefully in strict accordance with the scheme.

The plastic part allows you to firmly fix the LED elements, while the use of cardboard requires additional fastening of the LEDs to the base using liquid nails or superglue.

Since the device is designed to use six LEDs with a power of 0.5 watts each, three elements connected in parallel must be provided in the circuit.

A spectacular lamp can be made using LED strip. This element is inserted into the tube used for fluorescent lighting.

In a design that will operate on a 220 V power supply, the RLD2-1 driver must be provided, which should be purchased from a store or done by yourself.

It is important to isolate the driver and the board from each other using plastic or cardboard before starting assembly to avoid short circuits. Since the lamp barely heats up, there is no need to worry about overheating.

Having picked up all the components, you can assemble the structure according to the scheme, and then connect it to the mains to check the glow.

The device, powered by a standard 220 V cartridge, has low power consumption and a power equal to 3 watts. The latter indicator is 2-3 times less than that of luminescent devices and 10 times less than that of incandescent lamps.

Although the luminous flux is only 100-120 lumens, thanks to the dazzling white color the lamp appears much brighter. The assembled lamp can be used as a table lamp or for lighting compact space, for example, a corridor or a closet.
