How to open a light bulb. Possible options for how to unscrew the base of the light bulb from the cartridge. Method # 2 - plastic bottle

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.
    • Boca metal part must 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.
  • The question of how to unscrew a light bulb seems ridiculous and banal to many. Indeed, there are many different solutions. 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 voltage surge or a short circuit of the spiral, the bulb base (the metal element of the lamp designed to twist it) can be welded to the cartridge and, with excessive force applied, the glass bulb can break off from the rest of the lamp.

    The worst option is if you find yourself face to face with a problem, the bulb crashed unevenly, there were protruding fragments in the base, the lamp is in the lamp under the ceiling, which is quite difficult to remove, and the whole room was left in the dark. In this case, you should not panic either, your accuracy and following the correct procedure for further actions is important.

    How to unscrew the base if the light bulb is broken

    Greetings to all friends on the Electrician in the House website. 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 "exploding light bulbs". More precisely, incandescent bulbs often burst in the chandelier in the kitchen, and everything would be fine, if not for one thing.

    Unscrew the damaged light bulb from the socket chandeliers, and even with protruding fragments, as you understand, are problematic, especially for a girl. And to deal with the problem, she sometimes had to call an electrician. This girl came with advice on what to do in such a case and how to remove the remains of an exploding 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 for many people ignorant of electricity, it is not easy in such simple situations. Let's look at what are the ways to deal with the problem of a base stuck in a cartridge, I think it will be interesting not only for beginners.

    Even knowing how to unscrew the base if the light bulb is broken, you need to correctly assess the current situation. When lamps explode in their socket or are broken accidentally, their conductive parts may remain energized. Also, sharp edges of glass often remain on the broken part. 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 the electrical panel from several machines. In this case, we turn off only the machine from which the lamp (chandelier) with the damaged lamp is powered.

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

    Do not forget that during operation the light bulbs themselves and their bases get very hot. It is better to wait a few minutes and let the lamp cool down well. During this time, you can take care of possible fragments that, when removing the base, will begin to pour onto 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 devices necessary for further actions.

    There are several ways removing the base remaining in the cartridge Let's take a look at the most common ones.

    Method # 1 - pliers or thin-nosed pliers

    To solve the problem, we use thin-nosed pliers or pliers. Who does not know what thin-nosed pliers are - these are miniature pliers with elongated and thinner lips. They make it easier to capture 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. Try not to let them fall on the floor.

    Next, the base is gently grabbed by the edge with the selected tool and twisted 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, in one person in the evening broken light bulb in a three-arm chandelier. He decided to remove the base to screw in a new light bulb. In order to make it brighter, this "professor" thought of turning on the light on the lamps remaining in the work and climbed with pliers to the cartridge. He was so twitchy, ... therefore, before unscrewing the base of the light bulb from the cartridge, DISCONNECT THE VOLTAGE.

    Method # 2 - plastic bottle

    Another life hack that will help us deal with broken light bulb ordinary plastic bottle. Its neck fits perfectly into the base.

    In order to unscrew a broken 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 has hardened and soldered to the base, begin to unscrew the resulting structure. It takes about 10-15 seconds to melt and solidify the plastic.

    Method # 3 - unscrew the cartridge

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

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

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

    In one of the halves of the cartridge 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 - use a cork

    Next method if it burst, is to use a cork. We take a cork stopper, sharpen a little around the edges and insert it into a protruding base. Then we unscrew the cork together with the base.

    If the lamp shattered, and fragments of glass remained sticking out in the lamp, you can try to string a soft cork on them so that the fragments are tightly drowned in the crust. Next, the plug with the base carefully begin to turn. This is done before they fall out.

    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 connection diagram of the switch - it is connected to the lamp through the switch neutral wire(instead of phase), and phase wire 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:

    1. 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.
    2. 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.
    3. 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.
    4. 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 deteriorates. Therefore, when repairing the cartridge, it is advisable to replace it with a new one.

    How to connect a cartridge

    In order 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 connecting 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 a 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.

    LED lamps today are considered the most economical and durable compared to the rest. 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. fluorescent lamps require special disposal, as they have mercury vapor in the flask. In addition, breaking such a lamp at home, you can expose your household to the effects of poison.
    There are no such problems with LEDs. Throw them anywhere and smash them to health, they do not pose any danger, except for glass fragments.

    At the same time, there are a lot of companies producing these products, and choosing a quality product among them is sometimes not an easy task.
    Yes, and the eminent brand does not guarantee full confidence in the long uninterrupted operation of the device.
    What to do if the lamp has stopped 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 options for failure and its elimination is given.
    Of the tools you need only a screwdriver, a knife and possibly a two-handed indicator.


    If there is no indicator, any "dialing" will do.
    So, let's start by removing the diffuser. To do this, insert the knife blade into the gap between the glass and the plastic case and gently move it in different directions.



    The diffuser should come out of the latches and be removed without problems.


    A board with LEDs and a rectifier opens up.


    There is also a fuse on the board. To make sure that it is not burned out, we connect the ends of the dialing to its conclusions. Light or sound indication of the device will show its serviceability. If it doesn't show, you'll have to replace it.


    When the fuse is intact, we disassemble further.
    At the beginning, we unscrew the two screws securing the board, after which it can be easily removed.



    Under the board is a radiator in the form of a metal flask.


    The heat transfer of the board to the radiator is improved by thermal paste applied to both surfaces.
    If necessary, it can be changed if it is dry. A regular thermal paste for a computer processor will do.
    To continue disassembly, pull on the top of the lamp housing and it can be easily removed.



    In the lower part of the case with a cartridge, you can see two metal strips, one end connected to the base, and the other with holes - where the screws go.


    Thus, through the screw, voltage is transmitted from the base to the board.
    The problem turned out to be that over time, the contact bent and did not come into contact with the board screw. Hence the absence of the glow of the lamp.
    To eliminate this malfunction, simply bend the end of the contact strip with a screwdriver or tweezers.


    Of course, you can do it better, for example, by soldering the wires to the board and the base. Then there will be no problems with contact. But more often than not, the first simple option is enough.
    Now you can assemble the lamp in reverse order. We put on the upper part with a radiator so that two contacts fall into the holes.




    Next, install the board and twist it.
