What can be cooked from squid: quick and tasty

LED bulbs are considered to be the most economical and durable in comparison with others today. And although their cost is still relatively high, they are increasingly replacing incandescent and fluorescent lamps.
Why is this happening?
Mainly for two reasons:
1.Incandescent lamps burn out quickly and have low efficiency,
2. luminescent ones require special disposal as they have mercury vapors in the flask. In addition, by breaking such a lamp at home, you can expose your household to poison.
There are no such problems with LEDs. Throw them out anywhere and break them to health, they do not represent any danger - except for glass fragments.

At the same time, there is an abundance of firms that produce these products, and it is sometimes not easy to choose a high-quality product among them.
Yes, and a well-known brand does not guarantee complete confidence in the long-term trouble-free operation of the device.
What to do if the lamp stops shining, and it is impossible to change it under warranty. You can try to repair it yourself. Its device is not complicated and does not require special tools for disassembly.
This article will describe the disassembly and repair of a standard, budget-class LED lamp. In addition, one of the breakdown options and its elimination is given.
Of the tools you need only a screwdriver, a knife and possibly a two-handed indicator.

When an electric incandescent lamp fails, it can be used for various crafts. To do this, you need to know how to disassemble a light bulb. Use pliers and a screwdriver as tools. Gloves will definitely be needed to protect your hands from cuts. The components of the lamp are shown in the photo below.

What a disassembled lamp looks like

The lamp consists of electrodes with a spiral, a glass bottle and a base (in the photo - from left to right). The spiral is fixed on electrodes, one of which is soldered to the socket of the cap, and the other to its central contact. Insulating glass is located between the sleeve and the contact. When assembling the lamp, the sleeve is filled with an inert gas so that the coil does not quickly oxidize and burn out.

Fluorescent and energy-saving lamps contain poisonous tables of mercury inside, you need to work with them carefully so as not to damage the bulb.

Disassembling the lamp

An ordinary incandescent lamp is easy to disassemble, there are no harmful substances inside. This is done as follows:

1. It is necessary to grab the sealed contact at the bottom with thin-nose pliers, loosen it and turn it until the two wires leading to the glowing body are cut off, then remove the contact.
2. Use thin-nose pliers to gently break open the base insulator. This is done carefully as it is made of thick glass.
3. Remaining interior the light bulb (“leg”) is loosened and removed. The “leg” is made of glass and should be handled with care. Together with it, the filament body, electrodes and hooks are removed. Then the inside of the bulb is cleaned with a cloth.

Removing the "legs" of the incandescent lamp from the bulb

The work is connected with glass, therefore, it is done over a box or sheets of paper.

The result is an original container made of heat-resistant glass, which can be used for the following crafts:

• fill the inside with water and dip the stems of small plants, such as flowers, into it;
• pour to the bottom flammable liquid, lower the wick into it and use the light bulb as a source of light or heat;
• glue the bulbs together and fix them like a lampshade around the source of electric light;
• put inside a light bulb beautiful craft for example a sailboat;
• pour earth on the bottom of the flask and plant a small plant;
• apply as a miniature aquarium;
• make a small container for storing spices and choose a suitable lid that should fit the base.

If the metal base is not needed, it can be gently broken off by first scratching the junction with the flask with a glass cutter or a diamond file. You can dip the base in hydrofluoric acid or a mixture of hydrochloric acid with ammonium nitrate. After the metal dissolves, only the glass part will remain. You can also bend the base at the point of contact with the glass, then crush the glue and remove the flask. An old incandescent lamp does not have a very strong connection, as a result of which it becomes easier to separate the base.

Dismantling a lamp with a socket

If the lamp is unscrewed from the socket, it may break or detach without the base. To disassemble a cartridge, you need to do the following:

1. Gloves and goggles are worn to protect against glass splinters. If the lamp is high, you should wear a hat.
2. The electricity is turned off and the lack of voltage is checked by the indicator. The light bulb can be connected with a switch on the neutral wire, and not on the phase. In the electrical panel, the machine turns off, through which power is supplied to the lighting line (the light bulb belongs to it).
3. Next, you need to collect the fragments from the floor with a scoop and a broom and throw them into the trash. If there are glass remnants on the plinth, lay thick paper or cardboard underneath.
4. The base is unscrewed counterclockwise with pointed pliers. If it does not give in, it must be loosened by rotating it in both directions. You can try to unscrew the cartridge by rotating it counterclockwise. If this succeeds, it will not be difficult to unscrew the base in the future. If it does not unscrew by the edges, push the pliers apart and unscrew it with an emphasis on the inner walls of the base. The edges of the base can be bent inward with a flat screwdriver. Then you can better grasp them with pliers when twisting. The contacts of the cartridge lose their elasticity over time and deform when the lamp is screwed in. They need to be bent constantly when replacing lamps.

The compact fluorescent lamp consists of a lamp with an electronic ballast (ECG) built into the housing in the area of ​​the base. The lamp cannot be disassembled as it contains toxic mercury vapors and the trigger can be accessed for repairs. To do this, use a flat wide screwdriver to unfasten the latches one by one, as shown in the figure below.

Disassembly process of a compact fluorescent lamp

Old lamps are difficult to disassemble, since the plastic becomes hard from prolonged heating, and the latches break. They can be cut by walking several times with a sharp blade along the seam, and then opening the halves. In the future, they will have to be glued together. Disassembly will be easier if you heat the case with a building hair dryer.

Inside there is an electronic ballast connected to the contacts of the base with short wires.

How a compact fluorescent lamp works

First of all, a multimeter checks the serviceability of the filaments indicated on the board A1-A2 and B1-B2. Their resistance is 9-10 ohms. If an open coil is detected, it is shunted by a resistor with a power of at least 1 W and with the same resistance. This removes the diode shunting the filament.

Sometimes there is a fuse in the control circuit. If it burns out, a few ohms resistor is installed instead.

If the threads are in good condition, the condition of the board is checked: the presence of damage, burnt elements and the quality of the soldering. Then the serviceability of the parts is determined. Most often, there is a breakdown of transistors or a resonant capacitor. May fail: input limiting resistor, electrolytic capacitor, rectifier diodes.

Lamps burn out mainly at startup. Therefore, their durability is determined by the number of inclusions.

If both filaments burn out, the lamp can be recycled, and a serviceable electronic board can be used to power a tubular fluorescent lamp, if it is suitable in terms of power.

You can extend the life of the CFL by drilling small ventilation holes around the perimeter of the case (one row near the base and one in the middle).

Disassembly of the LED lamp

LED lamps are disassembled for repair purposes. You don't need to have a lot of knowledge in the field of electronics for this. First of all, the voltage supply to the contacts of the cartridge into which the lamp is screwed is checked. If there is power, but it does not light up, then the reason is in the lamp. In a simple way check is to screw a working lamp into the socket. The type of lamp is not important for checking the circuit.

LED lamp structure

• frame;
• base;
• light diffuser;
• block of LEDs;
• driver.

The case does not require tightness and the presence of a gas environment inside, although nowadays models that are completely similar in appearance to incandescent lamps have become popular.

The bulb is made of glass or plastic. In the upper part there is a plastic diffuser of light rays.

The bases are used the same as for incandescent lamps: E27 and E14. Foreign models have an E26 base and are often designed for a voltage of 110 V.

The block consists of several groups of LEDs, which are soldered onto textolite or aluminum boards. Each lamp is connected in series.

Drivers are power supplies that convert the input voltage to the optimum voltage for a group of LEDs. Transformer power supply circuits are widespread. Drivers can be built into the case or run as a separate unit.

Identifying damage

The diffuser dome is arranged with latches, which can be unhooked to gain access to the interior. It can be fixed to the case with screws that must be removed.

Disassembled LED lamp

After disassembly, the lamp power circuit is checked for external damage. If no burn-out of parts is found, they are checked using a multimeter.

You can see burnout on the LEDs. In this case, they must be replaced. The rest of the parts are also called, and the faulty ones are replaced. It is recommended to replace the current-limiting capacitor with another one with an operating voltage of 400 V. If it is designed for 220 V, it may fail. When a suitable LED cannot be found, a 0.25 W resistor is connected instead, and the rating depends on the lamp power.

The assembly of the LED lamp is carried out in the reverse order.

Incandescent LED Bulb

1. Remove the solder from the bottom contact of the incandescent lamp base by melting with a soldering iron.
2. Use sharp-nose pliers to break the black insulation glass.
3. Remove the glass leg with a screwdriver and remove everything from the lamp. Expand the hole as much as possible.
4. Solder a circuit of three LEDs by connecting them in parallel and adding a 56 ohm resistor to each. The resistor is soldered to the “+” LED (Figure below a). The resistance value may be different as it depends on the power source.
5. Solder two insulated voltage supply wires to the circuit.
6. Insert the resulting structure into the hole in the base and carefully unfold it inside the light bulb so that the wires do not close together.
7. Lead the power supply wires out of the base / plinth hole.
8. Check the serviceability of the light bulb by connecting it to a constant voltage source (Fig. B).
9. Fill the inside of the plinth with a hot glue gun and let it harden.

This way you can make a cheap and economical LED lamp, because the cost of the finished model is high, and often low quality products come across.

We disassemble the lamp. Video

The answer to the question of how to disassemble a light bulb correctly can be obtained by watching this video.

An incandescent lamp can be easily disassembled, many crafts can be made from it, but it is impossible to use the lamp for its intended purpose. Only the electronic control devices of the CFL and LED lamps located inside the base can be restored.

The question of how to unscrew a light bulb seems ridiculous and banal to many. Indeed, there are many different solutions here. However, situations often arise when burned-out light sources are in no hurry to leave their place in the lamp.

As a result of a surge in voltage or short-term closure of the spiral, the lamp base (the metal element of the lamp designed to twist it) can weld to the lamp holder and, with excessive force applied, the glass bulb can break off from the rest of the lamp.

The worst option, if you find yourself with a one-on-one problem, the bulb breaks unevenly, there are fragments sticking out in the base, the lamp is in the lamp under the ceiling, which is difficult to remove, and the whole room remains in the dark. In this case, you should not panic either, your accuracy and adherence to the correct order of further actions is important.

How to unscrew the base if the light bulb breaks

Greetings to all friends on the site "Electrician in the House". I was prompted to write another article on lighting by a girl who had problems with lighting in her apartment. The crux of the problem was the "exploding light bulbs." Or rather, incandescent bulbs often burst in a chandelier in the kitchen and everything would be fine if not for one thing.

Unscrew the damaged bulb from the socket chandeliers, and even with protruding fragments, as you understand, is problematic, especially for a girl. And to cope with the problem, she sometimes had to call an electrician. This girl asked for advice on what to do in this case and how to remove the remnants of an exploded light bulb.

To be honest, I never thought before that people could have such problems. But as it turned out in life, this is not so, and many people who are uninformed about electricity find it difficult in such simple situations... Let's look at what are the ways to cope with the problem of the cap stuck in the cartridge, I think it will be interesting not only for beginners.

Even knowing how to unscrew the base if the light bulb breaks, you need to correctly assess the current situation. When lamps explode in the socket or are accidentally broken, their conductive elements may remain energized. Also, on the broken off part, the sharp edges of the glass are often preserved. It is clear that you should not climb there with your bare hands, and rubber gloves are easy to cut through.

It is good when the room is powered in an electrical panel from several machines. In this case, turn off only the machine from which the lamp (chandelier) with the damaged lamp is powered.

If the room is dark, with an electric carrier and a table lamp, it is easy to build yourself a backlight using a nearby outlet on the other line. If this is not possible, use a flashlight or backlight on your mobile phone.

Do not forget that during operation, the bulbs themselves and their bases get very hot. Better to wait a few minutes and let the lamp cool down well. During this time, you can take care of possible fragments, which, when the base is removed, will fall on the floor. At the place of their planned fall, you need to spread a rag or film (in extreme cases, use a bucket or basin). Also prepare the tools needed for the next step.

There are several ways removing the cap remaining in the cartridge, consider the most common.

Method # 1 - pliers or pliers

To solve the problem, we use pliers or pliers. Who does not know what pliers are - these are miniature pliers with elongated and refined lips. They are more convenient for capturing small details. It is better to use a tool with insulating handles.

First you need to carefully tear off the remaining fragments of the lamp bulb from the base. Be careful not to hit the floor.

Next, the base is gently gripped by the edge with the selected tool and unscrewed outward. The main thing here is not to damage the circumference of the cartridge. But if you do everything carefully, there will be no problems. When the base does not move, you can try to bend its sides inward and only then try to unscrew it.

There was one case in my practice, one person in the evening a light bulb in a three-arm chandelier burst... He decided to take out the base in order to screw in a new light bulb. To make it brighter, this "professor" thought of turning on the light on the lamps remaining in the work and crawled with pliers to the cartridge. He shuddered so ... therefore, before unscrewing the lamp base from the socket, DISCONNECT THE VOLTAGE.

Method # 2 - plastic bottle

Another life hack that will help us cope with burst light bulb common plastic bottle... Its neck fits perfectly into the base.

In order to unscrew a burst light bulb, you need to slightly melt the neck of the bottle with matches or a lighter, put it in the remaining base and wait a while.

After the plastic hardens and is soldered to the base, begin to twist the resulting structure. It takes about 10-15 seconds to melt and solidify the plastic.

Method # 3 - unscrew the cartridge

One more convenient way, consists in disassembling the cartridge itself. But I want to note that this method will not work with ceramic holders, which are installed in most modern lamps and chandeliers.

This procedure can be performed only with carbolite cartridges of the old (Soviet) type. The difference between carbolite and ceramic chuck is that the former is collapsible.

The carbolite cartridge is disassembled into three main parts: two carbolite halves having threaded connection between themselves and the ceramic core on which the brass terminals (contacts) are attached.

In one of the halves of the socket there is a metal sleeve in the form of a thread for screwing in the lamp base. If this half is unscrewed from the base, then the base of the broken lamp will remain in it.

Method # 4 - using a cork

The next way if it bursts, is to use the cork plug. We take the cork, sharpen it a little along the edges and insert it into the protruding base. Then we unscrew the cork together with the base.

If the lamp has scattered, and fragments of glass remain in the lamp, you can try to string a soft cork on them, so that the fragments are tightly buried in the crusts. Then the plug with the base is carefully turned. This is done before they fall out.

Damaged light bulbs do not have to be thrown into the trash. Various crafts are made from them. For this, the light element is disassembled. In this case, a screwdriver and pliers are used as a tool. Also, do not forget to protect your hands, so wear gloves. How to disassemble a light bulb and what comes of it, we'll talk further.

We disassemble a lamp with a socket

When the lamp is unscrewed from the base, the glass part often breaks or detaches without the base. How to disassemble a light bulb without splitting it? To do this, follow the instructions:

1. Prepare your instrument. Do not forget about protective ammunition in order to avoid cuts.
2. With the help of thin-nose pliers, the contact, located in the depth of the base, is grasped, gently loosened and pulled out.
3. Using the same tool, break open the base / plinth insulator. Be attentive and careful. After all, this is a glass piece.
4. The base plate contact is removed.
5. After removing the contact, proceed to the inner filling of the bulb.
6. The elements remaining inside the product are loosened with a screwdriver, after which they are removed, carefully removing with the help of thin-nose pliers.
7. Special attention is paid to the glass leg, which is located inside the lamp.
8. At the last stage, the filament body is removed along with the electrodes and the element holder hooks, before finally disassembling the bulb.
9. If necessary, the bulb is cleaned, polished and aesthetically pleasing.

Dismantling the fluorescent lamp

Many are interested in the question of how to disassemble an energy-saving light bulb, but few ask if this can be done at all.

It is generally forbidden to disassemble a compact fluorescent lamp with an electronic ballast (electronic ballast) mounted in the case in the base / plinth area. The lighting element contains poisonous mercury vapors. To access the startup controller and repair the lamp, take a wide flat-bladed screwdriver and release the latches in sequence.

The lamp disassembly process is difficult. Products that have spent many days in operation are difficult to disassemble. After all, plastic, succumbing to prolonged heating, hardens, and the latches can break during the process of opening the lamp.

If the latches are broken, they are sawed off or cut off by walking with a sharp tool blade along the seam and then opening the halves. After such a reconstruction, the parts of the lamp are assembled back, gluing together.

Now you know how to disassemble a light bulb. And it will be easier to do this if you heat it with a construction hairdryer. Inside the product there is an electronic ballast connected to the contacts of the base using short wires.

How to disassemble an LED bulb?

Such a light bulb is hardly used for decoration or interior decoration. Disassemble devices only for repair purposes. Only a person with extensive knowledge in the field of electronics can understand how to disassemble an LED light bulb.

First of all, they check the supply of electrical voltage to the contacts of the cartridge into which the lamp is screwed. If the lamp is powered, but there is no light, try to determine the cause. Most likely, it is in the light bulb itself. To check this, a serviceable lamp is screwed into the same holder and checked to see if the light is on.

A glass bulb from a lamp can be used for a wide variety of purposes: for decoration, growing small ornamental plants, for example, succulents, DIY crafts. Can you think of original idea how to present such a decoration.

Grasp the seam with pliers. Look at the bottom of the light bulb and find a small metal joint. Grip this joint firmly with a needle-nose pliers.

• You will be breaking the glass during this step and during other processes, so it is best to work on a box or place a few sheets of paper underneath. You should also wear gloves and goggles.
