Replacing lighting lamps with your own hands. Rules for replacing a fluorescent fluorescent lamp

Hello everyone!

I have a lot of information on the site for repair and replacement LED backlight, but for repair lcd backlight and replacing CCFL lamps no information.

Well, this article, in some way, will correct this flaw.

Everything you need to know about backlighting before getting inside a monitor or TV.

1.The first and main signs of lamp problems:

- the image has acquired a permanent or periodic pink tint;

- the backlight goes out completely after switching on or after a while, while the sound remains, and the picture is viewed if you bring a lighting device to the monitor. A similar symptom may indicate problems with the inverter, which is responsible for transmitting the signal to the lamps.

1. Quantity lamps in LCD monitors are usually at least 4, and in TVs it can be counted as one or several. It depends on many factors: the age of the device, its diagonal, etc.

2. Before replacing, you need to make sure that the new light elements are suitable for the parameters. For this, there are tables for the correspondence of lamps to display diagonals. Better to follow her. It is possible that you will be able to put a lamp with a length difference of 1-2 mm, but it will take more time and effort.

3. The lamp replacement process for a beginner will take about 3-4 hours if you follow the instructions and do not experiment.

4. Caution does not hurt! When working with an inverter, be extremely careful, because its voltage output is approximately 1000V. And when you change the lamps, try not to break them, because they are very fragile and contain mercury vapor.

Process replacement lamps lcd backlight TVs and monitors.

For the lamp replacement procedure itself, you will need:

- a well-tidied room and clean surface;

- rubber gloves (medical gloves are perfect);

- a sharp thin knife (clerical for example);

- heat shrink tubes;

- Screwdriver Set.

So, you need to get to the lamps. First monitor (TV) must be freed from the protective plastic box - unfasten it from the narrow panel, which is located along the perimeter of the screen in front. Then carefully remove the entire LCD module from the metal frame by unscrewing a few screws.

Now the most difficult work, which requires patience and accuracy, begins - to disassemble the electronic panel and the module into components. To remove the matrix (and you will have to remove it), you will need to arm yourself with tweezers and peel off protective film from the electronic board (matrix decoder). This should be done carefully, because the thickness of the decoder is only 1 mm, and it is connected to the matrix by the thinnest data lines. If you try to cut the film or pull it harder, then a breakdown will inevitably occur, after which it will be impossible to restore the element's performance.

Removing the matrix, like other elements, is required with gloves, because finger stains will subsequently be reflected in the image. In the same way, dust and other debris will make themselves felt, so their contact with open elements should be minimized.

After removing the matrix, a set of filters and an optical fiber, where the lamps are located, will fall into the field of view. They can be arranged in pairs in pencil cases at the top and bottom of the monitor, or in horizontal rows along the entire perimeter of the screen. In rare cases, it may not be necessary full analysis LCD module, because sometimes the lamp cases take out more available ways... But all this can be learned only in the process of work.

When you get to the lamps, you can immediately notice the faulty ones - the blackened cathodes will tell you about it. But if visually the lamps look the same, then you will have to figure out which one to change. The way to substitute a working (better than a new) lamp will be the simplest. If this method cannot be carried out, then using a special device, you can create a resistance of about 1kOhm-2W through the inverter.

After replacing the lamps, perform the reverse process - collecting all the parts of the device into the original structure. Collect carefully so that there are no fingerprints or dirt, dust and foreign objects. If done correctly, your TV or monitor will work normally.

Replacing the standard CCFL lamps on the LED.

In devices with LCD system CCFL lamps are used or, in our opinion, fluorescent lamps, which glow not by heating the cathodes, but as a result of applying voltage to them. Therefore they are called cold cathode lamps. Such a light source should ideally change to an identical one. But we will take a quick look at replacing with an alternative LED lighting system:

• First, you will need to disassemble the device according to the above scheme.

• Remove lamps and remove inverter.

• Buy LED strip the right size and better white glow... You can find ready-made designs with a set of LEDs and a control device for them.

• The LED strip is glued onto double-sided tape where the fluorescent lamp was.

• Wires are connected to this structure, which are output to the board and soldered to where the 12V power is indicated.

• The operability of this circuit is checked and a monitor or TV is assembled.

This method has advantages and disadvantages. CCFL lamps unambiguously illuminate brighter and more evenly (more useful for the eyes), but LED strip is more affordable and more budgetary. This backlight is not adjustable. Although you can try to create more complex scheme control, which will take more than one hour (maybe a day) or it will be spent and buy a ready-made design with a controller. But, perhaps, the main advantage of LED backlighting is significant energy savings and durability (120 years !!).

How to change a light bulb in a stretch ceiling?

To change a light bulb in a stretch ceiling, it is not necessary to seek professional help. You can do it yourself. The replacement instructions will differ depending on the type of lamp installed.

It is not difficult to get a regular incandescent lamp, and before replacing other types of lamps, it is better to read the step-by-step instructions.

What are the reasons for replacing bulbs?

Stretch ceiling is a modern design solution that can decorate any interior. When choosing lighting, there is a lot of room for imagination - from a chandelier, led strip to spotlights different sizes and forms.

But sooner or later you have to change the bulbs. Why is this happening?

• The lamp is out of order. This is the most common reason, so you shouldn't skimp on buying a lamp. Then the replacement procedure will have to be carried out very rarely.
• Interior change... This common reason, which requires the dismantling of old lamps. But you don't have to remove all the bulbs. Sometimes the solution is to buy linings for Spotlights that will give them updated look... As for the chandelier, here you can redo each shade or purchase new ones.
• And another reason why the dismantling of lamps is inevitable is replacement of a whole canvas... It is impossible to change the stretch ceiling to a new one without affecting the fixtures.

If, for any of these reasons, it was decided to replace the sweetheart with another, then you should familiarize yourself in detail with the rules for dismantling each type of lamp. Thus, it will be possible to avoid serious mistakes.

Replacing the halogen lamp

This is one of the most popular versions of the luminaire, which is often used in soffits. He possesses high power, hence the short service life. To replace it with a new one, you need to follow simple rules.

• First you need to turn off the electricity in the room.
• Before work, you should wear cotton gloves, because the housing of the halogen emitter has elevated temperature... Do not touch the surface of the light bulb without gloves.
• Only after that the fasteners are removed, the old lamp is unscrewed and replaced with a new one.
• The new model is fixed with fasteners.
• It should be taken into account that the housing of the halogen lamp should be at a distance of at least ten centimeters from the canvas.

Replacing the LED lamp

Such lamps are convenient and profitable, because they do not require a lot of electricity. So, they will serve long term.

But nothing is eternal, therefore, sooner or later this light bulb-tablet will have to be replaced with a new one. How to do it?

• First you need to make sure that the electricity in the room is turned off.
• If the light bulb is replaced in the evening, it is better to take a flashlight with you to make it easier to navigate.
• After that, you need to remove the fixings of the old lamp.
• Then the insulation is removed from the wiring.
• After it is necessary to disconnect the wires.
• In order not to act "blindly", it is better to read the instructions for the new lamp.
• Then directly insert the new LED lamp.
• Then you need to connect the necessary wiring and fix the cover with screws.

Despite the fact that LED lamps require periodic replacement, they are still more economical and are very popular with stretch ceiling owners.

Replacing a spotlight

Working with this type of lighting fixture will require a little more skill.

• First you need to disassemble the box, disconnect the wiring and take out the old lamp.
• For a new luminaire, you need to open the box and connect the wires of the same color.
• Then using special pliers you need to crimp and close the wiring with a cap.
• When all the wiring is in the box under the cover, you can install the bulbs.
• Then you need to fix the lamp in the ceiling spot. Its power should not exceed that indicated on the flask.
• At the end of the work, you can turn on the voltage.

To properly remove the spotlight and screw in a new one, you need to take precautions.

• Turn off the electricity before replacing the lamp, otherwise it may cause electric shock.
• The springs must be held onto the luminaire, otherwise they will damage both fingers and the ceiling.

By observing these simple rules, you can easily unscrew the spotlight.

Which dismantling is considered wrong?

Some people mistakenly believe that replacing a fixture requires cutting the blade around it. But this option not only wrong but dangerous. Why?

• Firstly, it will be almost impossible to restore the canvas after such a procedure.
• Secondly, if you touch the wrong wire, it can shock you not weakly.
• The new luminaire must be of a larger diameter, because the installation site will increase due to the cut, and the old lamp size will not work.
• If the product is under warranty, then after such an intervention, it will cease to work.

With such an impact, the entire stretch ceiling can be irreparably damaged and the only way out is to change it to a new one. Therefore, if you are not confident in your abilities, it is better not to take risks, but to seek help from professionals.

How to remove a chandelier from a stretch ceiling?

It happens that to replace the lamp you need to remove the chandelier. You can do this yourself, following the recommendations.

• If the chandelier is hanging on a hook, then after removing the protective cap, you need to reach it with your hand and grab this mount. After removing the chandelier from the hook, it is necessary to work with the wiring, disconnecting them.

• If the chandelier has a cruciform bar, then dismantling it will be a little more difficult. To begin with, the lamp must be freed from the plafond, lamp and other decorations. Only after that the cap is unscrewed and the fastening system is disconnected (you just need to unscrew the screws). Then, by analogy, work with wires occurs.
• Experts advise against purchasing flat horizontal chandeliers for stretch ceilings, especially with incandescent and halogen lamps... Their heat can melt the canvas.

When replacing a light bulb on a stretch ceiling, it is worth considering some more nuances.

• If the stretch ceiling is with mirrored elements, then you need to change the lamps carefully in order to do without damaging the surface.
• It is better that the lamps are the same, otherwise the light supply will be uneven. Plus, uniformity always looks more aesthetically pleasing. If you can't find the right lamp, it makes sense to replace everything.
• Work better with gloves. This way the lamp will have a long service life.
• Luminaires with high power poorly combined with a stretch ceiling. It is not recommended to screw in a lamp with a power higher than 35 watts, otherwise there is a risk of damage to the material.
• For preventive purposes, do not overheat the devices unnecessarily, since any equipment needs a break in work.
• Better not to skimp on quality fixtures. They will last longer and will need to be replaced less frequently.

Thus, replacing a light bulb is not as difficult as it seems at first glance. The main thing is to strictly follow the recommendations, and everything will work out.

How to change a light bulb in a stretch ceiling, see below.

Lamps daylight have spread widely over the past several decades. Although more advanced light sources have appeared on the market, fluorescent bulbs are still popular for their economy and quality lighting. However, any technique breaks down, so over time, fluorescent lamps will need to be replaced. How to change a fluorescent lamp, there will be a speech below.

Required components

To replace a light source, you need the following set of components and tools:

• throttle;
• starter;
• 1-2 bulbs.

Disconnect the power supply before changing the lamp. Work under voltage is not permitted as it is life-threatening. It is recommended to carry out repairs with protective gloves - this will prevent injury to the skin of the hands from the sharp elements of the device.

Types of plinths

An integral component of the lighting device is the base / plinth. This part is used to secure the light bulb in the socket and supply electricity to it.

The following types of cartridges are used in fluorescent light sources:

1. E14. These threaded cartridges are called minion.
2. E27. Threaded mid-size plinths. They differ from the E14 only in size.
3. Pin base G. There are several types of cartridges (differ in the distance between the contacts) - G5, G13, G53. Also, the name sometimes contains a second letter indicating specific model(e.g. GU10).

Lamps with G5 and G13 socket

The most popular bulbs in ceiling lamps equipped with G5 and G13 plinths. These plinths are especially often used for lamps in kitchens, bathrooms, local lighting (for example, mirrors).

The most common cause of a fluorescent lamp malfunction is a lamp. Sometimes the choke or starter is the cause of the breakdown. A burned-out light bulb can be easily identified by the dark ring around the bulb.

Replacement instructions:

1. We purchase a lamp of the required size and power. If you have any difficulties with determining the characteristics of the lamp, we take it with us to the store. This will help the retailer to choose the right bulb.
2. We turn off the electrical appliance. To ensure safety, it is recommended to completely de-energize the room by turning off the electricity in the panel.
3. We dismantle the plafond (lattice of the lighting device). The plafond on the ceiling is fixed to the luminaire body using latches or screws. Sometimes the plafond is held by the lamp itself. To dismantle the plafond, just pull on any of its edges.
4. We unscrew the light bulb. We cover the lamp with both hands (closer to the edges of the bulb) and rotate it along the axis by 90 degrees. Pull the light bulb out carefully, but with little effort, so that the contact pins come out of the cartridge guides.

1. We mount the lamp into the lamp. We put it in the cartridge until it stops, and then rotate it around the axis by 90 degrees. The screwing direction does not matter.
2. We check the work of the lamp. If everything is done correctly, we return the lamp to its place. If the light does not appear, turn off the lighting and gently move the light bulb (turn it slightly). If these attempts are unsuccessful, we pay attention to the throttle or starter - most likely the problem is in them. Replacing the throttle and starter is a rather difficult operation, and it is better to entrust it to a specialist. In this case, it is recommended to install a new lamp, since the cost renovation works will cover the cost of buying a new lighting device.

Bulbs with G23 socket

Plinths of subspecies G23, 2G11 and GX23 are most often used for local lighting - in table and wall lamps. Caps differ in size and shape, but the principle of contact between a light bulb and a socket is the same everywhere.

To replace the lamp, proceed as follows:

1. We buy a light bulb.
2. We turn off the electricity.
3. We unscrew the lamp from the socket. We gently pull it by the edge of the bulb towards the plafond. The movement should be flexing to remove the bulb from the retaining clip. This must be done carefully without damaging the retaining bracket. When the light bulb is released from the clip, pull it out, swinging it slightly in the direction opposite to the cartridge.
4. Installation of a light bulb into a luminaire is carried out in reverse order... You need to insert the lamp into the socket and press the end of the bulb to push it inside. The successful installation is indicated by the click of the locking mechanism. Movements should be confident but careful. It is important not to damage the plastic retainer as it gradually wears out and breaks easily.

Note! A fluorescent lamp contains 3-5 milligrams of mercury. This item extremely toxic. Do not dispose of fluorescent light sources with other waste.

Replacement fluorescent lamp - simplest operation that even a beginner can handle home master... To complete the task, you only need care and accuracy.

Replacing a conventional incandescent light bulb is the simplest task. But when it comes to replacing a long tubular fluorescent lamp, many people wonder how to get it out of the body correctly. Despite the seeming complexity, this procedure does not conceal any insoluble problems.

Steps

Replacing the Lamp

Remember to turn off the power. Make sure to turn off the power before replacing the fluorescent lamp. It's not enough just to flip a switch on the wall. The lamp circuit power must be disconnected at the fuse box. Be sure to check the absence of voltage with a tester.

Prepare a ladder or other support. You will most likely find it uncomfortable to reach for the lamp from floor level. Place a ladder under the lamp for easy and safe lamp replacement.

Rotate the first lamp 90 degrees. Lift up and gently grasp the first lamp with both hands, holding it as close to the ends of the tube as possible. You can turn it in any direction a quarter of a turn until it stops. This will unfold the pins on both ends of the lamp to vertical alignment and then you can remove the tube from the lamp.

Gently pull the fluorescent light down along the groove. Put the lamp in safe place so that it does not roll or break.

Install a new fluorescent lamp. To install a new lamp, align the pins on the ends with the slots in the socket. Insert the lamp straight into the socket and then rotate 90 degrees until it locks into place. You can gently pull on the lamp to check that it is securely attached.

Repeat for the second lamp. Most often, fluorescent lighting fixtures will be designed for two parallel lamps. The process of replacing both lamps is the same.

Check the new lamp. First restore power to the shield, then use wall switch... Check that the new lamp is working, remembering that the fluorescent lamps take about a minute to reach full brightness. If the new lamps do not work properly, then it is necessary to check the functionality of other elements of the luminaire.

Examine the ballast. Ballast controls the amount of incoming voltage required to turn on the lamp. It also adjusts the electricity for a constant glow. If you think the problem is ballast, then it is better to buy a new fixture, since replacing the ballast will cost you about the same amount.

• The hum produced by the luminaire almost always indicates the need to replace the ballast, and not the lamps themselves.

1. If flickering, check the fuse box. The lamp power may be insufficient. Try to reset the unit by turning the circuit breaker off and on.

   Wipe down the light. While the glass is on the floor, use the opportunity to remove dust, insects, condensation or mold.

The scheme of removing the luminaire from stretch ceiling is not obvious, it is unlikely that you could remove the light bulb without theoretical foundations this process. Not worth trying! Amateur work with electrical appliances can lead to disastrous consequences both for the ceiling and for you! Read the removal instructions carefully lighting fixtures and only then dismantle.

If your bulb is out of order, an immediate bulb replacement is required for optimal lighting performance. But not everything is so simple: sometimes you have to remove the lamps from the socket to remove the lamp. Depending on the type of lamp, you will need to take different steps to replace it.

How to change the lamp:

1. If your luminaires use conventional lamps incandescent, you just need to turn off the light in the room, unscrew the old lamp and screw the working model into its place.
2. To replace halogen or led bulb, then you have to work a little. So, first, turn off the power supply in the room, then remove the lamp cover and remove the locking ring. If you are dealing with a halogen lamp, then remove it with a cloth or gloves. Oil from the fingers can shorten its lifespan. To remove the lamp, try wiggling it with soft, unsharp motions. If the light bulb does not work, then gently twist it around its axis.

It happens that luminaires with LEDs are a single mechanism. In this case, replacing the bulb is not possible, and the entire lamp will have to be replaced!

How to change an LED lamp in a stretch ceiling

LED lights are very beneficial and convenient. They consume a small amount of electricity, shine brightly enough and serve regularly for several years. One way or another, the work of an LED lamp sometimes comes to an end and with it the need to change such a lamp.

Replacing the LED lamp is as follows:

• Take a new lamp and make sure it works properly with a tester (sometimes this can be done in a store).
• Turn off the electricity in the room before proceeding with the replacement.
• Provide yourself with self-contained lighting. It is unlikely that you will be able to cope with the task blindly.
• Remove the fixing from the damaged light bulb.
• Strip the insulation from the wiring.
• Disconnect the wires.
• Read the instructions for the new lamp carefully.
• Install the lamp according to the instructions.
• Reconnect all wires and restore electrical insulation.
• Hide the wires and attach the cover of the LED light.
• Attach the crusher to the box using screws.

The need to change periodically LED lights pays off in their economy.

How to remove a lamp from a stretch ceiling: remove a chandelier

Removing a chandelier from a stretch ceiling is a snap! If you are too afraid to learn an electric shock, then de-energize the entire apartment. This will completely protect you, and the whole procedure for removing the chandelier will go smoothly.

Step-by-step instructions for removing a chandelier from a stretch ceiling:

1. If your chandelier is suspended on a hook, then remove the protective cap, stick your hand through the gap formed, and find the hook that holds your chandelier. Grasp the chandelier securely at the attachment point and remove it along with the wiring. Now we are working with the wire. Carefully strip the insulation and disconnect the wires. Ready!
2. To dismantle a chandelier with a cross-shaped bar, you will have to do a little more action... First, remove all elements from the lamp: lamps, shades, decorations, etc. Then unscrew the cap. Find the fastening system under the hood. Now detach the hangers by unscrewing the screws and pull out the chandelier along with the fastening structure. Next, remove the insulation and unwind the wires. Your chandelier is free!

If your chandelier weighs a lot, then don't rely on yourself! Get an assistant to secure the chandelier during the removal process.

How to remove a spotlight from a stretch ceiling: we eliminate possible problems

In the process of removing the lamp, some problematic situations may arise due to the fact that not everyone knows how to properly remove spotlights. If you study the removal scheme in detail, then of course everything can be avoided.

The main problems when removing lamps are the following:

• The springs securing the lamp above the ceiling hit the fingers painfully when the lamp is pulled out.
• There is a risk of electric shock.
• If the springs of the lamp are very strong, then when removing the lamp, they can damage the strobe.

To prevent these problems, do not forget about the main rules: always turn off the lights before removing the lighting fixtures, and also hold the lamp springs firmly enough so that they do not damage the ceiling or your fingers.

Take care that the electricity is turned off during the installation or dismantling of lighting fixtures.
