How to install or change a light bulb at home

Replacing a light bulb usually does not present much difficulty even for non-specialists. But not everyone knows how to change a light bulb if it is installed in a hood, spotlight, microwave or refrigerator. And replacing a burnt-out light bulb in a regular lamp requires compliance with certain rules.

How to correctly replace a light bulb in a lamp, chandelier or lampshade

If a light bulb in your home lighting fixtures has burned out and needs to be replaced, then first of all you should purchase a new one. It is necessary to install a lamp of the same power and the same type.

The following type of light source can be used for lighting:

1. Incandescent lamp.
2. Energy saving or fluorescent lamp.
3. Halogen.
4. LED.

The light bulbs installed in the luminaires have maximum power limitations. Usually it is 40 W. This value cannot be exceeded, since the sockets and wiring in the lamp may fail.

Having found out what type and power the burnt light source in the chandelier or lampshade is, you need to clarify the type of base, after which you can purchase a new light bulb. If difficulties arise in determining the parameters of a burnt-out light bulb, you can simply dismantle it and take it with you to the store as a sample.

Then you can start replacing. It is advisable to wear safety glasses and gloves before working.

• De-energize the device.To do this, you need to turn off the machine on the dashboard or unscrew the plugs. If it is a table or wall lamp, just remove the plug from the socket.
• To change a light bulb in a chandelier or ceiling light, you will need a stable stepladder or chair.
• Remove the light bulb and install a new one in its place.

If the bulb appears to have burst or crumbled when unscrewed, the remaining part of the incandescent lamp can be unscrewed from the socket by grasping the edge of the base with pliers or pliers.

When replacing an incandescent lamp in a chandelier hanging overhead, do not look at it. This will protect your eyes from splinters if the bulb bursts. To avoid accidentally cutting your hands, you need to wear gloves or wrap the lamp in a napkin.

If an energy-saving light bulb is installed in the lampshade, then it must be unscrewed by holding it by the base, and not by the fragile glass tubes, which can easily break. Inside these light sources there are vapors of mercury compounds that are very harmful to health.

When replacing halogen lamps, they should not be handled with bare hands. Fatty fingerprints will cause local overheating of the flask and its destruction. Therefore, before working, be sure to wear gloves.

Waterproof lamps are usually installed in the bathroom. When dismantling the lampshade, care should be taken not to damage the insulating elements. It is necessary to provide a place where the removed lampshade and tools can be placed during work. After replacing the burnt-out light bulb, the lampshade is installed in place so that vapors and moisture cannot get inside the device.

How to replace a light bulb in a suspended or suspended ceiling

How to change a light bulb in a suspended ceiling if it is equipped with spotlights? Replacing the light source in them requires care and certain skills. This is especially important when working with tools, if the lamp needs to be replaced in a suspended ceiling. One awkward movement can damage the stretched fabric. To replace a burnt out lamp:

• Turn off electricity in the room.
• Remove the fixing ring from the lamp that holds the lamp in the shade and place it so that it is at hand.
• Carefully disconnect the burnt out lamp. Depending on the base model, it can be screwed into the socket, fixed with side pins (rotated 90 degrees) or have pin contacts.
• If you did not know before which model of lamp is used in the lamps, then you need to take the burnt-out light source with you to the store as a sample and buy the same new one.
• Install the new light bulb into the socket, place it in the socket and secure with the ring.

Since halogen light sources are usually installed in spotlights, you need to wear gloves to avoid leaving sweat marks on the lamps.

How to replace a light bulb in a kitchen hood

If the backlight in the kitchen hood stops working, but the fan turns on normally, then most likely the lamp has burned out. It's easy to replace it yourself. First of all, you need to completely de-energize the hood by unplugging the plug from the socket. Depending on the model, access to the lamp can be achieved by removing the air intake grille or opening a special lamp on the body.

Then everything is simple - remove the faulty light bulb, and in its place put a new one of the same type and power. After this, you need to connect the current and check the operation of the lighting.

You cannot install a light bulb of a different marking and power in the hood, as it may damage the wiring or simply will not work.

How to replace a light bulb in a refrigerator

If the light in the refrigerator has disappeared and the engine is working properly, then most likely the lamp has burned out. Knowing how to replace a burnt out light bulb, you can do it yourself without contacting a repair service. The lamps can be located in the refrigerator in different places - on the side or back wall, in the upper part or in the middle of the chamber. But, in any case, access to them is provided. Before starting work, you must turn off the refrigerator and remove the plug from the socket.

The easiest way to change the lamp is in the Veko refrigerator. A 15 W light bulb with an E14 base is screwed into a socket located next to the switch. You just need to unscrew the faulty light source and install a new one in its place.

It is not much more difficult to replace the light source in the Biryusa refrigerator. To replace a burnt out lamp in a Biryusa refrigerator you need to:

1. Disconnect it from the network.
2. Open the refrigerator door.
3. Most modifications of Biryusa refrigeration cabinets have a box with a cooling regulator on the right side wall. A lampshade with a lamp is attached to it on the back side. The lampshade should be gently squeezed from the sides (to release the latches) and removed.
4. Unscrew the burnt out light bulb and install a new one in its place.
5. Replace the lampshade.

Some models of Biryusa refrigerators use an LED block (Biryusa-10) as a light source. To dismantle it, you need to remove the cover from the block, unscrew two self-tapping screws, remove the block together with the lampshade, and disconnect the contacts.Installing a new light source in the Biryusa-10 refrigerator is done in the reverse order.

In Samsung refrigerators, the lamp cover is removed differently for different models. So, for Samsung RL series (38**, 41**,44**), it is attached with latches, and to remove it, you just need to press on the sides and pull it towards you.

In other modifications of Samsung, the cover is fixed with a screw that must be unscrewed. If there is a protective housing under the lampshade, then you need to unscrew the fastening screws and remove it. Disconnect the wires. If there is protective tape, it must also be removed. After this, a new one is installed instead of the faulty light bulb.

Changing the light source in an Indesit refrigerator is not very difficult, but care must be taken. The fact is that in most Indesit models the lampshade is not completely removed, but part of it is bent, opening access to the light source. To gain access to the lamp, you need to unscrew the fixing screw and bend the desired half (according to the instructions). A burnt-out light bulb in Ariston refrigerators is replaced in the same way. But on some modifications (for example, Indesit C138G), the lampshade is removable and secured with latches. To dismantle it, you need to press on the top and bottom walls.

Atlant refrigerators also use an incandescent lamp for lighting. To properly dismantle the lampshade, the manufacturers put an arrow on the wall next to it. Replacing the light source in all Atlant modifications is carried out as follows:

1. Turn off the power to the refrigerator by unplugging the plug from the socket.
2. Unscrew the screw that fixes the lamp.
3. Without applying much force, move the lampshade in the direction indicated by the arrow on the inner wall of the Atlant refrigerator.
4. Replace the burnt out lamp.
5. Reinstall the lampshade.

In Atlant refrigerated cabinets, you can replace the incandescent lamp with a more durable one - LED. For comfortable lighting of the refrigeration chamber, such a light source will have a power of 3-5 W. In addition, LED bulbs practically do not heat up.

You can use LED light sources to illuminate cameras not only in Atlant refrigerators, but also in devices from other manufacturers, if they are equipped with incandescent lamps operating from a 220 V network.

Halogen or energy-saving light bulbs are not used for illumination in refrigerated cabinets.

How to replace a light bulb in a microwave oven

Most modern microwave ovens are equipped with backlighting. If the light bulb in the microwave burns out, this will not affect its performance, but it is still more convenient to use it when the lighting is working. Not everyone knows how to replace a light bulb in this kitchen appliance without resorting to the help of specialists. To do the job you will need a Phillips screwdriver and a little skill. The operating procedure is as follows:

• Disconnect the appliance completely by unplugging the plug from the socket.
• Carefully examine your “helper”. It is necessary to find and unscrew the screws that secure the housing cover (usually it is U-shaped and covers the sides and top of the device). Fastenings can be located on the back or sides (less often - on the front or bottom).
• Carefully remove the cover. Usually it needs to be moved back a little and then raised up.
• Determine the location of the light bulb.In some models it is placed in a special box secured with a screw. Inside there is a socket with a light source that needs to be replaced. In other models, the socket itself is inserted into a special hole along with the lamp, and secured on the outside with one or two self-tapping screws. By removing the socket, you can easily replace the faulty light bulb.
• Replace the socket or lamp box and secure it correctly.
• Close the housing cover and secure with screws.
• Connect to the mains and check how the lighting in the microwave works.

It is better to purchase a light bulb after dismantling the burnt one, using its sample, since it is difficult to determine in any other way which light source is installed in the microwave.

Replacing an oven light bulb

You can change the backlight lamp in the oven yourself even during the warranty period. The lighting can be located in the oven on the side or back wall (depending on the model). The light bulb can be covered with a round or rectangular glass cover-shade.

Replacing the light source in the oven is carried out in the following order:

• Unplug the oven. If it is hot, wait until it cools completely.
• Cover the bottom with a cloth or towel. If a light bulb or glass cap accidentally falls, it will not break.
• If the light bulb is covered with a round cap, then it must be unscrewed by rotating counterclockwise. After this, remove the metal and sealing rings.
• If the light source is closed with a rectangular lid, then you need to insert a flat object (a screwdriver or the tip of a knife) into the groove on the top and, turning it up, push out the glass plate.
• Replace the light bulb in the socket.
• Cover the hole with a lampshade.Round - screw it on, after putting rings on it. Rectangular - insert the bottom edge and then press lightly on the top to snap into place.

Only heat-resistant light bulbs rated for temperatures up to 300°C can be installed in the oven.

If the oven uses a halogen lamp for illumination, fingerprints must not be allowed to remain on it. You must either wear gloves or wrap the light bulb in a dry cloth. Contaminated areas should be wiped with a cloth soaked in alcohol.

Disposal of used lamps

The easiest way to recycle incandescent lamps. They are made of glass and metal. They do not contain substances harmful to the environment. Therefore, they can simply be thrown into the trash container.

The same can be done with LED light sources.

Halogen lamps contain small amounts of halogen and halogen compounds in the bulb. But they do not pose a danger to living organisms and the environment if the flask is destroyed.

The bulbs of fluorescent lamps contain mercury or its compounds belonging to class 1 toxic substances (“extremely dangerous”). They should not be thrown into trash containers. Failed fluorescent light sources must be handed over to public utilities or to special collection points, where they must be accepted free of charge and disposed of in accordance with sanitary standards.

Energy-saving lamps are a type of fluorescent light sources. They must also be handed over to the appropriate organizations for recycling.
