The fastest way to remove the base from the light bulb. How to disassemble a light bulb: real tips to help craftsmen

Repair or replacement of the lamp socket.

Call an electrician to replace the light bulb socket or replace the socket yourself?

If you decide to replace or repair yourself, then you need to consider some features.

First Feature.

After the switch has been turned off, before starting work with the cartridge, check the voltage at its contacts (or on the supply wires). Sometimes there are errors in the switch connection diagram - a neutral wire (instead of a phase wire) is connected to the lamp through the switch, and the phase wire is connected directly to the cartridge. With this scheme, when the switch is off, voltage remains on one of the poles of the cartridge. Be careful!

The second feature. If the light bulbs in the bathroom, in the toilet or in the kitchen have stopped burning, do not rush to change the cartridge. In humid and damp rooms, as a rule, connections and contacts are oxidized. Clean the contacts, check the presence of voltage with a probe - a screwdriver (carefully - do not close the poles).

Third feature. Low quality cheap ammo. Unlike older domestic cartridges, inexpensive new cartridges are unreliable. Their bottleneck is contacts (central and lateral). Due to the heating and the presence of moisture, the parts are oxidized, or rather the connections between them.

How to detect a defect?

In the off position of the switch, unscrew and remove the light bulb from the socket.
If the lamp is broken, using a tool with an insulated handle, carefully unscrew the base. We are convinced of the serviceability (malfunction) of the cartridge - we screw in the lamp, turn on the light - it does not light up. Turn off the switch, unscrew the lamp. We disassemble or remove the cartridge.
Unscrew the outer cylindrical body of the cartridge (but there are one-piece cartridge structures - then the cartridge can be removed from the mount by unscrewing 2 screws - see photo).
Carefully inspect, check the integrity of the central and side contacts. If they have defects (burnt, mechanical damage), then it is necessary to replace the entire cartridge.

How to replace cartridge?
To replace the cartridge, you need to know their design. There are 4 most common cartridge designs:

Domestic - carbolite, base E-27. Collapsible, carbolite body, porcelain liners. Reliable at work. Therefore, it is possible to replace a single damaged node. See photo.
Ceramic "Chinese" design, base E-27. Non-separable. Attached to surface with 2 screws. The contact plates are connected to the terminal contacts with rivets (the most unreliable knot). If any assembly is damaged, the cartridge must be replaced. See photo.
Ceramic domestic design, base E-27. Porcelain case, demountable from two halves. Pressed metal or porcelain threads. There are hanging, end and street with ears for suspension. Dismantling or replacing such cartridges does not require special skills.
Plastic with end fastening, socle E-14. The halves of the body are fixed on plastic latches. The supply wires are fastened with spring or screw clamps. In such cartridges, the plate passing in the cavity of the plastic thread does not make good contact with the base body. The brass plate and the aluminum base oxidize, the compressive force between them weakens and the contact worsens. Therefore, when repairing the cartridge, it is advisable to replace it with a new one.

How to connect a cartridge

To connect a light bulb socket to a 220 volt network, you will first need a voltage indicator.

How to disassemble a light bulb holder

Unscrew the bottom of the cartridge and take out the ceramic core with contacts. We make sure that the bolts that hold the bracket contact plates (on the side where the bulb is screwed in) are well tightened. If possible, tighten them with a screwdriver for a strong connection.

How to connect the cartridge e27, e14 to the wire

When connected find the phase with the voltage indicator on one of the two connected wires.

The second wire will be zero, respectively - check this.

Light bulbs and lamp sockets

Unscrew from the top cartridge core two contact bolts for wires. We thread the upper cap of the cartridge into the wire, because then putting it on will not work. We put each bolt on both loops made in advance from the wire and clamp these two bolts back.

From an electrical point of view, it does not matter which wire is in which of the two clamps. But it is important for safety compliance. Therefore, always connect the phase wire to the terminal located in the middle, and the neutral wire to the side, (threaded) terminal. With this connection, a person, when screwing in a light bulb, even if the energized chandelier cannot physically touch the phase. Since she is deep in a lamp socket.

How to assemble a light bulb holder

To the top cartridge cap we settle the already connected core and twist the lower part back. After we screw in the light bulb of the corresponding base diameter E27 or e14 in the cartridge. Apply voltage to test.

Grab the solder joint with pliers. Look at the bottom of the bulb and look for a small metal joint. Grab this joint firmly with needle-shaped nippers.

You will be breaking glass during this step and during other processes, so it's best to work on the box or lay down some sheets of paper. You should also wear gloves and goggles.

Twist and pry out the metal. Turn the joint with pliers until you feel the copper part break one or two wires leading to the filament inside. When the metal base is free, remove it.

Grab the light bulb firmly with your other hand as you remove the metal bottom.
You may need to wiggle the sides of the plinth back and forth slightly if twisting doesn't work.
The sides of the metal part should be sufficiently embossed so that you can grab a good grip with pliers while lifting the plinth.

Break the glass insulator. Hold one side of the black glass insulator at the bottom of the bulb with pliers. Twist it to break the glass.

The glass in this place is thick, so you will have to make an effort to break it. Make sure you hold the bulb firmly with your other hand.
The insulator will break into many pieces during this step, so don't forget about safety.
You may need to break the insulator at different angles around the perimeter if it doesn't break completely the first time.

Remove all fragments of the broken insulator. Using tweezers, clean the light bulb base from fragments of black glass insulator.

These shards will be very sharp, so you should not pick them up with your bare hands.
After removing the glass of the insulator, you will see the internal components of the light bulb from below.

Remove the inner filling tube. Insert a flathead screwdriver into the bottom of the bulb, next to one side of the outer fill tube. Press down on the side of the tube with a screwdriver to pull it out.

The lamp will be filled with argon or a similar inert safe gas. When you pull out the tube, you will hear a sound indicating the release of argon gas.

Pull out the tube. Insert a screwdriver between the tube and the lamp to release the tube completely, then pull it out with pliers or tongs.

If you can successfully free the tube without breaking it, you can use it for something else.
If you are unable to pull the tube out by prying it around with a screwdriver, you may need to apply more force and break the tube. Remove the fragments with tweezers when finished.
You will have to put in a lot of effort, so make sure you have a firm grip on the bulb with your other hand.

Used light bulbs are garbage. But if you are a super creative person with a wild imagination, then for you this light bulb will be an element of decor in the house. You can place an eternal terrarium, sparkles, water, colored cotton wool, threads, photos and much more in a glass lamp. You can also make a garland, a panel or a lampshade from such glass material. But in order to make decorations, you must first know how to disassemble the light bulb yourself.

"Lamp" instruction

To start creating, you first need to get everything unnecessary out of the light bulb. Follow the instructions and do not violate the safety rules. In order to disassemble the incandescent lamp, take thin-nosed pliers, a light bulb and a screwdriver.

Instruction:

we unscrew the burned-out light bulb from the cartridge;
we take thin-nosed pliers, at the bottom of the base we find a contact and loosen it to pull it out;
then we break the base insulator to pull out the bottom of the contact;
we take a screwdriver and try to loosen all the insides of the lamp with it, pull them out with thin-nosed pliers;
then we take out the electrodes, the filament body and the hooks holding the filament body;
wipe the lamp with a dry cloth from the inside.

As you can see, disassembling a light bulb is not difficult, but you still need to be careful not to cut yourself. The insides are mostly glass, and if you break them, you can get very hurt. So it's better not to compress the tools too much.

But remember that you can only disassemble an incandescent lamp, because it does not contain harmful substances inside, but it is better not to touch the energy-saving one.

What to do if suddenly the lamp gets out without a base? Of course, this is good for disassembling the lamp, there is less work, but you still need light in the room, so you can get the base from the cartridge as follows:

We put on a hat, glasses and gloves. Working with glass is dangerous, so it's better to play it safe;
turn off the electricity and check the voltage;
we proceed to unscrew the base, it is unscrewed with pointed pliers counterclockwise. If suddenly it doesn’t work out, try to loosen it;
after you have the plinth in your hands, remove all the glass from the floor.

What can be made from an empty lamp? Many people like to make crafts from things that are not intended for this at all. Light bulbs are no exception.

Interesting! Such a beautiful decor as an eternal terrarium will look great in a small light bulb.

In order to make it you will need: moss, forest soil, tree bark, pebbles, sand, water, acorns. At the bottom we put pebbles that serve as drainage for us, then sand goes, then we put soil, moss and wood, pour a couple of drops of water and close the terrarium.

With all these "ingredients" we create a small ecosystem, so the terrarium will develop.

You can also make a container for storing spices, such as pepper, salt, sugar, from a light bulb. You can also just paint the lamp in a beautiful color or wrap it with twine. You can make small vases for flowers or funny figurines of fairy-tale characters. Perhaps it will be a bright garland or a small Christmas decoration, or maybe a tiny balloon.

Home decor is good, but saving money doesn't hurt anyone either. Therefore, if you want your lamp to last longer, do not turn it off and on too often, always check the serviceability of cartridges and sockets so that electricity flows without interruption. It is also desirable to have protection against power outages, which will protect not only the lamps, but also all the appliances in your home. Remember that jokes with electricity are bad, do not forget to turn off the light when leaving the room or even leaving the house. This will help save money, the lamp, and your home.

LED lamps are no longer dismantled for the purpose of decoration, but for the purpose of their repair. If they do not burn, it is worth unscrewing them and screwing others into the same cartridge. If the testers give light, then it's not the cartridge. So, let's start disassembling the light bulb.

Can LED bulbs be disassembled? Of course, it’s better not to disassemble at home, but it’s still possible. The instructions for proper disassembly of the lamp are described below.

Instruction:

unroll the body;
after we consider the motherboard: if no burnouts were found, then we take a multimeter and with the help of the device we check again all the details;
we replace damaged parts with new ones;
put the body back.

Reasons why LED lamps burn out:

complete burnout of one LED, as a result of which the lamp stops shining due to a violation of the current supply through other light diodes;
burnout of one of the current supply chains. If the lamp does not shine so brightly, then the reason is precisely in the fuse of the chain;
flickering of a diode that has not yet completely burned out.

The LED lamp is an energy-saving lamp, but its cost in the store is much higher than the cost of a conventional lamp. But there is a way out: you can make it yourself, or rather, remake it from the usual one. To do this, remove the solder on the bottom contact of the base. Work is carried out according to the following scheme:

heat up the soldering iron;
break black glass with pliers;
remove everything from the lamp;
solder three LEDs in turn and add 56 ohm resistors to each;
solder two insulated wires to the circuit;
we insert everything into the lamp and already level it inside, we take out the wires from the hole;
fill the base with hot glue.

Factors affecting the service lifelamps:

Voltage level, or rather, excess voltage.
Ammo failure.
A large number of on and off lamps.
Switch failure.
Quality of wire connections.

Important! Choosing the right light bulb for your home is important. The power should be 13-15 W, this is enough for one room. It is also important to buy a lamp with a 75-90 color rendering coefficient, with an aluminum heatsink.

Do not forget that LED light bulbs are harmful to health and lead to many diseases and even cancer. This is due to increased UV radiation. Vision also deteriorates due to oxidative processes in the retina. If the lamp suddenly breaks, there is a risk of mercury poisoning. Therefore, it is better to buy such bulbs for rooms where light is not used so often. If the light bulb is screwed into a table lamp, then there should be a distance of 15 cm from the eye to the lamp.

If we talk about choosing a chandelier or lamp, then it is better not to take closed shades, otherwise there is a risk of overheating of the chandelier, which can lead to undesirable consequences.

How to remove the base from the light bulb?

The hardest part of disassembling a light bulb is removing the base. The base helps the lamp to gain a foothold in the cartridge, it also transmits current. It is difficult to take it out, and it consists of two parts: upper and lower. How to disassemble the lamp and remove the base? In order to remove the base, we take pliers, grab the base, loosen it and pull it out. It is advisable not to squeeze the pliers strongly so as not to damage the base. It happens that the base gets stuck in the cartridge. How to separate the base from the cartridge? We take pliers, pull out the base from the cartridge in the same way as from the light bulb. Just do it carefully so as not to damage the cartridge itself.

In order to understand when buying which base is in one or another lamp, you should know the following designations:

E - Edison threaded base;
G - pin base;
R - base with recessed contacts;
B - pin base (bayonet);
S - soffit base;
P - focusing base;
T - telephone base;
K - cable base;
W - lamps without base.

Small letters indicate the number of contacts:

s - single-contact;
d - two-pin;
t - three-pin;
q - four-pin;
p - five-pin.

There are 7 types of socles: threaded (incandescent), pin (halogen), pin (in car headlights), soffit (car interior lighting), focusing (movie projectors, flashlights), telephone (remote illumination), with recessed contact (quartz halogen).

Before you run to the store for light bulbs, look at what shape your cartridge is, so as not to make a mistake with the choice of base. The form depends on the type. If it is a threaded view, then it should be threaded, if it is a pin, then the base looks like a plug from a plug. The most common type is threaded, as it is used in almost all types of light bulbs.

An incandescent light bulb is an excellent material for crafts by home craftsmen. It can serve as an element of decor or a convenient vessel for various purposes. There are several ways to dismantle its insides. To understand how to disassemble a light bulb, you need to decide on its purpose in the "second life". Separating the bulb from the base and extracting the insides from the whole lamp are different procedures.

Dismantling while maintaining the base

The operation itself is simple. But since during the work there is always a risk that the glass bulb may burst, it is worth taking precautions. To prevent fragments from flying far, disassembly can be done over a cardboard box or cover the workplace with a cloth. This will help collect the broken glass. It is very important to observe safety measures: use gloves and goggles during manipulations. It will be useful to wrap the flask with a suitable towel. To work, you will need the following tools:

pliers, pliers or wire cutters;
screwdriver;
tweezers.

Destruction of the insulator

The first step is to remove the contact on the bottom of the base. For this grabbing the disc with pliers, you need to carefully loosen it and then turn it until the contact wire breaks. Under the removed metal washer, a hole will open through which the electrical connection thread passed. It will serve as a hook for pliers or wire cutters in the next procedure - the destruction of the black insulator. The latter must be painted very carefully, since the glass chips that fill the base of the base are extremely sharp.

There is another way to open a light bulb, which involves the partial removal of its bottom. To do this, you need to saw off part of the base approximately in the place where the thread begins. This can be done with a hacksaw, but often the base metal is so soft and thin that a regular knife will be enough to cut. The bottom is then separated along with the black glass insulator.

Opening and removal of the insides

After removing the insulator, the sealed leg of the glass bulb with conductors protruding from it will become visible. You have to carefully break it down. It's not worth putting in a lot of effort. At the time of the destruction of the tube, you can hear a soft pop due to the depressurization of the flask - in old devices, glass cylinders were evacuated so that the filament did not oxidize. Now the flasks are filled with an inert gas, usually a mixture of argon and nitrogen.

Now you need to use a screwdriver to break the leg of the central holder of the tungsten filament. Removing it from the balloon will not be so easy. If you break the glass to the rim of the base, the entire bulb may crack. It is necessary to carefully expand the hole and try to remove the insides by pulling the antennae of the conductors or shaking out the lamp. If this cannot be done easily, use tweezers.

Opening by cutting the flask

So, the instruction on how to open a light bulb in order to save the base involves extracting the insides through the bottom of the contact part. But often, for the further use of the lamp, it is not necessary to keep its base. In this case, the problem of how to pull the insides out of the light bulb disappears by itself - the task is to cut the bulb at the base with high quality and separate everything superfluous from it.

thermal method

It is based on the fact that with a rapid change in temperature due to uneven expansion, the glass is destroyed at the point of stress. To control the process, it is necessary to locally heat the flask along the line of the future cut, and then cool it sharply. For this you will need:

silk thread;
alcohol;
container with water.

First of all, you need to wrap the base of the bulb with a thread. It does not hurt to mark the future line of the plinth separation by marking it with a glass cutter. A ring of wound thread is wetted with an alcohol liquid and ignited. During combustion, you need to rotate the bulb for a uniform and complete burnout. As soon as the flame goes out, it is necessary to immerse the hot area in a vessel of water. As a result of thermal shock, the light bulb will crack exactly along the line of the most intense heating.

After cutting the flask, the edges of the chip should be smoothed out on sandpaper. This procedure is best done by moistening the paper with water so that fine glass dust does not accidentally enter the respiratory tract or eyes.

mechanical way

It consists in cutting the flow at the base of the cylinder with various tools. The easiest way to do this is with a diamond needle file with edges. You can make a cut with rotation tools - on a grinding wheel or with a dremel with the appropriate discs. In this case, it will be useful to wrap the cut with insulating tape in one layer and make a cut directly along the tape. This method does not require water cooling, therefore it is not difficult if you have a tool and abrasives suitable for this.

There are other methods for disassembling light bulbs, such as cutting with a laser or nichrome thread using electricity. But they can be too demanding on equipment that the home master does not always have at hand. It is important to remember that all of the above methods of opening are applicable only to incandescent lamps. In no case should luminescent devices be disassembled by similar methods - they contain highly toxic mercury vapor, therefore their disposal is carried out only at specialized enterprises.

Damaged electric lamps do not have to be thrown into the trash. They make various crafts. To do this, the light element is disassembled. In this case, a screwdriver and thin-nosed pliers are used as a tool. Also, don't forget to protect your hands, so wear gloves. How to disassemble the light bulb and what comes of it, we'll talk further.

We disassemble the lamp with a cartridge

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

Prepare the instrument. Do not forget about protective ammunition in order to avoid cuts.
With the help of thin-nosed pliers, the contact located in the depth of the base is grasped, gently loosened and pulled out.
Using the same tool, the base insulator is broken open. Be attentive and careful. It's a piece of glass, after all.
The contact of the bottom of the base is removed.
After removing the contact, proceed to the internal filling of the light bulb.
The elements remaining inside the product are loosened with a screwdriver, after which they are removed, carefully removing them with thin-nosed pliers.
Special attention is paid to the glass leg, which is located inside the lamp.
At the last stage, the filament body is removed along with the electrodes and the hook-holders of the element, before finally disassembling the light bulb.
If necessary, the light bulb is cleaned, polished and given an aesthetic appearance.

Disassembly of a fluorescent lamp

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

It is generally forbidden to disassemble a compact fluorescent light bulb with an electronic ballast mounted in the housing in the area of \u200b\u200bthe base (electronic ballast). Inside the lighting element contains poisonous mercury vapor. To gain access to the launch controller and repair the lamp, take a wide flat screwdriver and unfasten the latches, observing in turn.

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

If the latches are broken, they are sawn off or cut off by running the blade of a sharp tool 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 building hair dryer. An electronic ballast is placed inside the product, connected to the base contacts using short wires.

How to disassemble the LED lamp?

You can hardly use such a light bulb for decoration or interior decoration. Devices are disassembled only for the purpose of repair. Understanding how to disassemble an LED light bulb can only be done by a person with extensive knowledge in the field of electronics.

First of all, they check the supply of electricity to the contacts of the cartridge into which the lamp is screwed. If there is power to the light bulb but no light, try to determine the cause. Most likely, it is in the light bulb itself. To check this, a working lamp is screwed into the same cartridge 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, such as succulents, DIY crafts. You can come up with an original idea how to present such an ornament.
