False ceiling lamps are often used in spotlights. Some do the installation of the structure themselves and then they have an idea how to change the halogen light bulb in the false ceiling and any others. It's not essential. But if you ordered the installation of the ceiling from the company and did not do it yourself, then you may not know how the replacement is done.
On our site you can see photos and videos on the installation of various structures in suspension systems. Below is a step by step guide to do this job.
Applied products
Light bulbs in a false ceiling are most often used in four types.
How to unscrew, screw in, insert dotted halogen products with your own hands
- Halogen, which can be installed with a minimum ceiling clearance in relation to the base. They produce quite bright light. Replacing such an element is a little more difficult than an incandescent lamp, and one must be extremely careful. The life of such a lamp is highly dependent on the correct installation. We have frequent drops in the supply of lighting, which adversely affect the operation of incandescent appliances. Therefore, it is better to use voltage stabilizers on the branch;
- Some use lamps with traditional incandescent lamps.. These elements are well known to everyone and their replacement is not difficult. However, they are far from suitable for all false ceilings, as they get very hot;
Fluorescent
- Fluorescent lamps, despite the fact that their price is quite high, they are very popular, as they consume little electrical energy. At the same time, their luminosity is much higher than that of analogues. Among the shortcomings, one can note the slow inclusion (lamps with hot start). As well as a limited number of on-off cycles, as well as the content of mercury vapor in them, which complicates disposal.
False Ceiling LED Downlights
- LED lights for false ceilings the most economical and durable. The luminosity of such devices is often higher than that of fluorescent ones. Their service life can reach 72,000 hours, which is incredibly long. For comparison, a conventional incandescent lamp has a lifespan of 1000 hours.
When replacing lighting fixtures, there are a few things to be aware of.
It is mainly used for spot lighting two types of base:
- With traditional right hand thread. It applies to a standard cartridge. And everyone knows how to make such a replacement;
- There are lamps that are attached with two pins.(base G with various modifications). They serve as guides and are fixed after a characteristic click. When replacing, do not press hard. If you hit the groove, then snapping will happen easily. Therefore, do not try to press, just pull it out and try again, perhaps the element did not fall into the groove;
Getting to work on the replacement
Turn off the power
First you need to turn off the power supply on the branch. Don't forget about safety. To do this, just make sure that the switch is in the "off" position.
After that, we find a convenient support so that we can work at height. Use a stepladder or regular stool.
Advice! When working in suspension and tension systems, you should be extremely careful. If it is a stretch ceiling, then the fabric can be easily damaged. If the suspension rack system, and even with a mirror coating, then this, too, any careless movement can be harmful.
- If there is an incandescent lamp in the ceiling, then you need to grab the bulb and turn it counterclockwise, that is, it is held by the base.
- LED, halogen and fluorescent lamps have a different mount.
- When removing, first of all, you should unlock the light bulb in the housing. There is a fixing ring for this. When doing this work, hold this part, the ring itself is springy and can easily slip out of your hand.
- In other designs, the ring is threaded and unscrews in a counterclockwise direction.
How to unscrew, screw in, insert the lamp correctly
- Now the lamp is free. She won't fall as she hangs on the wires. Pull it outward and disconnect the connection by simply pulling it to the sides.
- Having taken out the lamp, you can see its face value and choose its replacement.
- The lamp is installed in the reverse order.
To make the lamp not only work for a long time, but also look beautiful in the ceiling, it is enough to follow a few simple rules:
- If you do not have enough lighting in the room. There are two ways you can go about correcting the situation. The first is to choose a lamp of greater power, and the second is to replace it with a more energy-efficient option - LED.
- If it was just uncomfortable for you to work, then try taking a daylight llama with a temperature of 4000K. Such lighting is more conducive to the working environment.
- Lamps in a suspended ceiling use the same model, otherwise they will not look very good together. If this is not on sale, then it is better to replace all the lamps in the room, unless of course it hits the pocket hard.
- If you put a halogen lamp without a reflector, for example, in a chandelier, then remember that you cannot take it with your bare hands. The fact is that their bulb is covered with a special coating that degrades upon contact with fats - such a lamp will not last long. Use the cloth or cellophane that comes with the kit.
How to remove, disassemble, unscrew the built-in lamp
Now you know how to replace light bulbs for a false ceiling. The case is simple, but not devoid of certain subtleties. Let your home be bright and cozy.
Good day!
In this post, I would like to consider such a sore LCD monitors as failed backlights, try to figure out why this is happening, and change them accordingly. Interested please follow the little green man.
P.S.
Under the cut contains 27 photos
-Dear, I apologize in advance for the quality of subsequent photos, photographed on a toaster ....
-Also, I want to note that monitors do not differ much in their fundamental structure, so do not be alarmed if you suddenly do not find screws or something else in the place that is shown in the photo, they are somewhere nearby ...
So, we have a monitor that works almost in romantic, red-pink colors. The operating time of such a monitor is unpredictable ... but as a rule it does not exceed 2-3 hours, after which your eyes are given time to rest, and your brain to think about the issues of life.
The problem lies in the failed monitor matrix backlight, but why did this happen?
There are many reasons for this situation:
- manufacturing defect,
- shorting the metal parts of the lamp to the metal frame of the matrix,
- physical damage, etc.
But let's get a little deeper into the theory.
LCD matrices work through the light, that is, the monitor must have a light source that shines through the matrix. The quality of the monitor depends quite significantly on the light source. For stationary LCDs and TVs, direct backlighting is usually used, when light sources (lamps or LEDs) are distributed over the entire area of \u200b\u200bthe panel. ©
But why does he continue to work then? And such a short period of time?
Everything is simple.
It should be noted that monitors most often use 2 blocks of 2 lamps ( top and bottom of the monitor), which should evenly distribute light along the light guide under the matrix.
If one or more lamps fail, the rest continue to work. But the inverter which feeds them) is a smart thing, and if he “sees” that something is wrong with one or more of his wards, he decides to stop his work so as not to harm.
Well, let's proceed to the disassembly, shall we?
We start by disconnecting all the loops from the inverter unit and the monitor controller,
Remove the back panel with the power supply and controller
Removed? excellent ... What do we see, in numbers 1
we have marked power wires going to the treasured lamps.
2
- a loop going to our matrix.
Asterisks mark places that need to be tucked in order to continue disassembly
We are currently removing the panel on the left, we do not need it now
And again we disassemble our "matryoshka" 
Excellent, almost half way gone,
now let's explain:
5
-our matrix (the same thing with numbers 640x480 ~ 1920x1080)
6
-signal decoder connected to the matrix by row/column data line
7
-light guide with filters
Next, we again delve into the "monitor jungle" and remove the plastic frame around the perimeter ... 
Under the black frame are 2 thin films lying on top of each other, and under them is a light guide.
8
-light filter
9
-polarizing film
10
-light guide
Now take out the big acrylic thing ( 10
) and finally we can see the heroes of the occasion ...
The assholes that made us come this far 11
)
Lord. I present to your attention broken faulty backlight lamps!
Speaking of lamps.
Do you know:
that LCD panels use CCFL lamps, which in Russian means a cold cathode fluorescent lamp. Its principle is almost the same as hot (in the common people "fluorescent lamps"). The only difference is that in order to obtain plasma in a hot one, the initial heating of the cathodes is used, and in a cold one, the plasma is obtained due to the high voltage applied to the cathodes. Further, the plasma, which has an ultraviolet radiation spectrum, hits the phosphor, the white coating that you see through the flask, and is converted by the latter into visible radiation (white light) ©
As we can see, they really burned out. (the “black marks” around the cathodes hint at this)
We unscrew them, having previously pulled out the reflective substrate ( maybe you don't have to do it on your monitor)
... and swap them ( I want to note that it is worth being careful, because they are quite fragile. I also advise you to securely fasten the wires and watch so that there is no breakdown in the future. Let's isolate everything!)
Now we're going to put our bulbs back in place, screw them on, put the reflective thing back in place, and put the light guide back in place.
We connect - everything works! ( Before that, it also worked, but not correctly, only 1.5 lamps were on, I did not bother to capture this action in disassembled form. I confess)
Well, well ... the hardest part is over, it remains to put everything back together.
Let's get started. 
We return the films to their place, close them with a plastic frame and lay our matrix on top, fix it with a metal frame.
(Here we should not forget about such a thing as dust... before assembling everything, it is worth blowing all the components of the monitor with air, it will not take long, but it will affect the image quality)
Turn over and return the last “detail” to its place
We connect to the "stand" and rejoice!
Everything works, there are no traces of uneven illumination,
Flight is normal.
Fin.

.Replacing the lamps yourself is not so difficult, there would be a desire.
You can also experiment and replace the lamps with LED strip. But you need to remember that the LED strip does not give a completely uniform light + to everything, it may very well be that 1 or more LEDs will burn out / become a little dimmer, and then the backlight will become uneven. Also, do not forget about the color temperature of the LEDs.

. Why did I decide to write this article?
Faced with the repair of the monitor for the first time, I reached into "some search engine" I didn't see detailed instructions...
no, I'm not saying that I didn't find them, they were, but they seemed incomplete to me, that's why it was decided to collect this material and post it here. Few people need it...

Question:
Good afternoon, I have a false ceiling installed in my room, but the lamps in it began to go out. I tried to pull it out myself, but I can't unscrew it. The canvas is deformed, the lamp is not pulled out. I'm afraid to damage the ceiling. Tell me how to restore the backlight?
Answer:
Stretch and suspended ceilings are often used to decorate the interior and the embodiment of design ideas. The lamps that are installed in them are called spot or “spot”, which is translated from English as “Point”. In these, both 12-24V lamps and the usual 220V can be used. The design of the device, although typical, but different cartridges are installed in them, the lamps in them are also fixed in a different way. This approach helps to make a multi-zone ceiling light that is appropriate both in the home and in the office. Let's find out how to change a light bulb in a false ceiling without damaging it.
What lamps are used in spotlights
In stores you can find a number of products for spotlights, they differ in both voltage and design. When replacing a lamp, you need to pay attention to both factors:
- Supply voltage - 12, 24 or 220 V.
- Plinth type.
The supply voltage of 12V allows the use of such lamps in any premises, including wet ones - in the bathroom and kitchen. The type of base already depends on the lamp itself, there are a lot of them for spotlights, among them the most common ones can be distinguished:
- GU5.3;
- GU10;
- GX53;
Generally speaking, they can be divided into two groups:
- Threaded plinth.
- Pin (the lamp must be inserted with or without turning).
The last difference is the type of lamp:
- Incandescent lamp;
- Halogen;
- Luminescent;
- LED;
The last two types are called "Energy Saving". Let's figure out how to change the LED and any other light bulb in a spotlight.
How to remove a light bulb from a stretch ceiling: 4 rules
Layout of a spotlight in a suspended ceiling The spots are fixed not in the stretch ceiling, but in the main. Its frame is mounted on the ceiling, and its decorative part is located on the stretch fabric. The cartridge can either be fixed on the spot frame, or simply hang on the wire, and the lamp is fixed in the lamp, we will talk about this in more detail below. The main thing when replacing is to adhere to the following rules:
- Use a stable ladder or stand. This is a must, because you can’t lean on the stretch ceiling with your hand, you will damage it.
- use gloves. Halogen lamps must not be touched with bare hands. If greasy marks remain on their surface, this can lead to premature failure of the lamp. It is worth thinking about replacing the halogen with diode counterparts.
- When servicing MR16 luminaires, you need to carefully remove the stopper so as not to lose it, otherwise the lamp will fall out.
- Make no effort. When removing the light bulb or the spot itself, you need to be careful not to damage the stretch ceiling or drywall, determine the type of lamp and read the instructions for replacing it.
Replacing lamps MR16, GU5.3
Location diagram of a spotlight with a GU5.3 base Luminaires for MR16 with GU5.3 base hold the lamp with a retaining ring. It is rather not a ring, but a bracket. Let's learn how to pull the light bulb out of the spotlight.
- Turn off the power. In order not to get an electric shock, it is better to turn off the electricity completely, because the switch does not always break the phase wire, although the correct circuit involves disconnecting the phase from the light bulb.
- If there is a decorative cover on the lamp - remove it.
- Squeeze the locking bracket with two fingers for the antennae provided for this. Now you need to take it out. The removed stopper can easily jump out of your fingers, be careful.
- The lamp will hang on the wire, now you need to remove it from the base, holding on to it. Do not pull on the wire, so as not to tear off.
- Assemble everything in reverse order and install the retaining ring in its place. Please note that there are slots (windows) on the lamp body for this.
There are some nuances. If the stopper does not sit in its place, this may be due to two reasons. The first is that the lamp was not inserted completely or its body was not made according to the standard. The second - perhaps the ring is not from this lamp, you could mix them up if you changed several lamps at once.
Instead of a spring stopper, there may be a threaded ring. We simply unscrew it and repeat the described steps.
Replacement of lamps type GX53 (tablet)
GX53 spotlight layout diagram The GX53s are actually pill-shaped, usually round with a matte white diffuser. Consider how to change gx53 light bulbs in a stretch ceiling. The procedure for replacing them is a little simpler than that of GU5.3. There are two pins on the lamp, but they are of a different shape. The pins have two diameters, the one closer to the lamp is smaller, and the one closer to the edge is twice as large. This is necessary to fix the light bulb in the cartridge. You don't have to disassemble anything here.
To replace such a light bulb:
- Grasp the flask with one hand.
- With the other hand, hold the frame of the lamp.
- Rotate the lamp counterclockwise by 20 degrees.
- Pull out the lamp.
- Install a new one by turning it clockwise until it stops.
It is not necessary to get the GX53 out of the cartridge if it does not go. The design provides easy extraction, it should also be inserted simply. It is fixed by turning and inserting the stops on the pins into a narrow place on the connector in the cartridge.
Replacing bulbs with sockets E14, E27
Light bulbs with such cartridges are less common in spotlights than pin ones, but still. They just need to be unscrewed and removed from the lamp. Now we will tell you how to change in a spotlight. Depending on its design, there may be a retaining ring, as described in the first type of lamps, or the lamp itself can be removed from the ceiling. On plasterboard ceilings, these are held by spring-loaded paws located opposite each other and separated in different directions under the action of a spring. It is necessary to carefully remove the spot from the ceiling, without damaging the latter, after which it will be convenient to unscrew the light bulb and screw in a new one. The stops under the action of tension will close towards each other and release the lamp.
Replacing a luminaire in a stretch ceiling
The luminaire in the stretch ceiling is fixed through plastic mounting rings. The spot itself rests on spring-loaded paws. The paws rest against the ring through the stretch fabric. To remove such a lamp, do just two actions:
- Grasp the ring in the stretch ceiling with your hand, resting slightly on it.
- Pull on the lamp housing.
The springs will succumb to the forces, and the stops will come out of the ring.
Rings can be located on the reverse side of the stretch film. Do not mindlessly pull on the body, do it with smooth, but confident movements. Usually the wire to the cartridge is long enough, should not create obstacles.
We told you how to change the LED lamp in the stretch ceiling, now let's learn about some of the subtleties. Our advice will help you do this without damaging the wiring and ceiling coating, as well as quickly burning out the lamp.
- If the lamp burns out in the same place more often than others, the problem is in the cartridge. Pin bases are not designed for high power, so it is better to use energy-saving lamps, then the base will last longer, but if it is already damaged, replace the lamp or cartridge.
- Do not touch the flask - use napkins and gloves. In addition to visual defects, this can lead to burnout of halogen light sources, which we have already mentioned. Such lamps need to be taken through a napkin or with gloves, simple HB from a hardware store will do. If they were not at hand, you can even use medical ones. A napkin will also help to avoid problems. The last option is paper tape.
- If the lamp does not go, do not use force. It can stick to the cartridge, this happens due to power surges, overheating. Duct tape or paper tape will help. You can paste over the protruding edge of the flask and pull the edge of the tape. Thus, you will apply more effort without harming the ceiling.
Mistakes
The main mistake is the use of powerful halogens. For example, the GU5.3 base does not tolerate lamps over 40 watts. To make the lighting brighter, add a number of fixtures, or use LED or fluorescent fixtures. With the same power consumption, LEDs shine five or more times brighter. The price of LEDs has fallen significantly over the past five years, and the quality of products has become higher. They are suitable for both backlighting and general lighting.
If you already have high-power LED devices installed, try white glow lamps. Warm light visually seems dimmer and softer, although they give the same luminous flux.

Replacing a light bulb in a lamp - it would seem, what could be easier? However, even in this matter, people face problems. How to choose and how to change a light bulb? What nuances should be taken into account when replacing lighting in a particular room? What to do if you need to replace the lamp built into the pendant
Types of lamps used
What is the difference between lighting devices of various varieties and what are their pros and cons?
- One of the most famous types of lighting fixtures is a glass bulb, inside of which there is a spiral, most often made of tungsten. The action of the electric current causes the spiral to heat up and emit a warm yellow light. The main advantages are cheapness and availability for the buyer, while the disadvantages are low efficiency: a much larger resource of electricity is spent on heating the air than on giving off light, and a short lamp life.
- More modern and perfect look of standard incandescent lamps. The tungsten filament is placed in a flask filled with halogens - vapors of bromine, iodine, chlorine, which increase the evaporation time of the tungsten filament and significantly extend the service life of the device. The light is more even and bright, similar to daylight. The main obstacle to the widespread use of halogen lamps is their cost - it is much higher than the cost of incandescent lamps.
- They got their name due to the substance phosphor, which allows you to convert energy into light. They are famous for their good efficiency indicators: even low lamp power gives good illumination indicators. A large number of compact options are now being produced, adapted to standard cartridges in fixtures. An important feature of the operation of such a lamp is the content of mercury vapor inside the flask, so they must be disposed of at special collection points.
- This model is characterized by lower energy consumption and good light performance. Such lamps are much more durable than incandescent lamps and are the best option to use. However, their cost is even higher than the cost of halogen lamps: the price of one piece varies from 250 to 700 rubles.
Each of these types of lamps has its own characteristics, advantages and disadvantages. Despite the obvious advantage in terms of durability and environmental friendliness of modern halogen and LED lighting products, people are stopped by such factors as their high cost. Also, people often have no idea how to work with such varieties and how to change a light bulb. It is often worth paying attention to the energy consumption in individual areas of the house. For kitchens and rooms, halogen bulbs are great because they have the best balance of durability, energy savings and cost. Before you change the light bulb in the bathroom and bathroom, you need to understand what level of illumination you need to provide. If buying LED elements is too expensive, you can replace them with halogen lamps, which provide good overall light and are quite durable.
How are the lamps attached?
How to change a light bulb in a chandelier? To do this, you need to know what types of fastening lighting devices exist. There are several ways in total. The most famous is the right-hand threaded mount, when the light bulb is screwed into the socket clockwise. Before you change the light bulb, you need to understand what type it belongs to: when installing an incandescent or energy-saving lamp, you should not press on it, to fix it, you just need to turn it clockwise. In addition, there is a fixation option with two guide pins: they are placed in the groove, and then it is installed with a click. The third type of light bulb requires a 90 degree turn after placing it in the groove.
false ceiling
First of all, you need to ensure your own safety by turning off the power supply and arranging the workplace in such a way that it is convenient to work. Ease of use is extremely important, since the procedure must be carried out carefully and carefully so as not to damage the ceiling covering. This is especially important when replacing lighting fixtures built into suspended and stretch ceilings. At the first stage of work, it is necessary to unlock the ring that fixes the lamp in the housing. After that, it gently turns out and is replaced with a new one. It is necessary to determine the lamp power when replacing it in order to ensure the same level of illumination of the room. Upon completion of the procedure, it is necessary to fix the ring back, securing the light bulb in the socket.
When buying an LED element, be sure to check the quality of combustion by pointing the phone's camera at the lamp. If the light is pulsating, chances are it won't last long due to poor build quality, so it's worth getting another one. When choosing lighting fixtures for a room, it is better to stay on lamps of the same variety and model: then the illumination and light temperature will be harmonious. How do you change a light bulb to brighten up a room? To do this, it is not necessary to choose a more powerful or capacious element. It is enough to replace all yellow light lamps with white light fixtures: this will help to increase the luminous flux and achieve a higher level of illumination.
With the advent of cheap LED light bulbs on the market, the question of replacing them arises more and more often. To replace, you must first know the type of base. The figure below shows examples of LED type: E-27, E-14, GU-10, GU-5.3, G-9, G-4, GX53.
When replacing a light bulb, you need to pay attention to what type of lamp was installed in the spotlight. There are several types of spotlights:
- The MR-16 LED lamp is used in the DL-11 fixtures;
- LED lamp minion E-14, used in built-in spotlights brand R-63;
- luminaires GX-53 closed type.
Consider the examples of how to change the LED light bulb in spotlights.
Always switch off mains power before replacement!
Replacing a GU5.3 or GU10 LED Bulb
Such a base is often fastened with a retaining ring. In the cartridge, they are fastened with two conductive pins until they click (GU5.3) or by turning 90 degrees (GU10). Replacing them is quite simple according to the following instructions.
- Turn off the mains power;
- before replacing, check the power of the lamp being replaced. It must correspond to the power burned out. If you put a more powerful lamp, you can ruin the controller or transformer, if installed. When installed, they are calculated for a certain indicator of the power of the connected load;
- remove the retaining ring, which is located along the diameter of the housing. Pull gently on it, and the bulb will easily come out of the spotlight. If the ring has two protruding antennae inside, just squeeze them;
- remove the light bulb from the cartridge, holding the base with the other hand, install a new one;
- put the retaining ring back into the groove.
Replacing lamps E-14 and E-27
For this type, replacement is even easier. It is necessary to unscrew the old bulb counterclockwise and screw in a new one clockwise, while de-energizing the room in advance. It is necessary to screw in until it stops, without applying any effort.
Pay attention to the plinth. E-27 is a well-known standard, the diameter is like that of an ordinary incandescent bulb. E-14 - base of smaller diameter. If in doubt, take a burnt out light bulb with you when buying.
Closed type GX53
They are often called a pill. These are some of the easiest lamps to operate and replace. The easiest way to change them is:
- Turn off the mains power;
- take the lamp and turn it counterclockwise until it stops. The angle of rotation is not more than 10-20 degrees and it will freely fall out of the grooves;
- insert a new tablet into the grooves and turn clockwise until it stops. Ready.
These miniature light bulbs are similar in design, they differ in size, but the principle of installation is the same for them. Due to their low weight, they are attached only to the base to the cartridge. Additional fasteners are usually not provided. Consider how to replace such a light bulb in a spotlight.
- De-energize the lamp by turning off the mains power;
- if there is a decorative light diffuser, remove it;
- we take the body of the light bulb and pull it out with a light effort;
- install a new one by inserting the pins into the cartridge. If you have a halogen, when installing, only handle it with gloves or a napkin.
Replacing light in furniture lighting
Any spot lighting of furniture and kitchen equipment in 99% of cases is replaced by one of the above methods. The whole complexity of the replacement lies in the dismantling of the decorative diffuser cover.
Strict requirements for the appearance of the luminaire force designers to hide the fasteners as much as possible and you need to show imagination in order to understand how to remove this or that luminaire.
Precautionary measures
- Always turn off mains power when replacing;
- before replacing, try to wait for the lamp to cool completely (read:);
- twist the light bulbs in the glass case with special care. Over time, under the influence of temperature changes, the material loses its strength. Take special care of your eyes;
- if there is insufficient contact between the conductor and the cartridge, under the influence of high temperatures, the light bulb body can “stick” to the base. In this case, it is better to disconnect the cartridge itself from the wiring and continue dismantling at the bottom.
