Ilyich's classic bulbs began to be replaced more often with modern LED lamps. LEDs are more reliable, have several glow options (daytime, cold, warm, others). The service life of lamps is several times higher than that of classic lamps - manufacturers claim tens of thousands of hours, but in practice such lighting mechanisms stop working much faster. To understand why LED lamps burn out, you need to familiarize yourself with the reasons.
The main reasons for failure
Faulty or rotten electrical wiring in an apartment or car is the main reason for LED bulbs to burn out. Most of the cables were laid many years ago, so parts and wires are worn out. Changing the wiring is long, expensive, and not always possible.
"Human factor" - mistakes of electricians, builders, other craftsmen are not uncommon. Incorrect calculation of the required voltage, poor connection of contacts, selection of unsuitable elements - all this leads to arcing of the network, failures, disconnections and other problems.
"Wrong" lighting devices (sconces, chandeliers, lamps) - another reason for the constant burnout of LEDs. About a third of the voltage consumed is spent on lighting, the remaining 2/3 are converted into heat. Therefore, when developing devices, it is necessary to take into account the heating of the crystals and provide for the possibility of timely cooling.
The main advice is to use medium power lamps (about 5-7 watts). They generate less heat, which means they heat up less and last longer. It is recommended to purchase 4-watt lamps instead of 12-watt lamps.
Only a professional electrician can often understand why LED bulbs burn out.
Faults and wiring defects
LEDs burn out with frequent power surges and surges. Problems arise on power lines, during a thunderstorm, directly in the room. Timely checking the integrity of the wires will help to avoid unexpected breakdowns and reduce the frequency of burnout of LED lamps.
LED lamps do not perform well under low voltage conditions. Check the quality of the connections in the junction box, remove twists and kinks. Old switches and blocks can also cause energy saving light bulbs to burn out prematurely.
Checking the chandelier, identifying defects
Chandeliers have a simple structure and the main "problem" place is the cartridge. Malfunction symptoms:
- excessive heating;
- sparking;
- blackening and carbon deposits.
If in a multi-lamp chandelier, bulbs often burn out in one place, then there are problems with the cartridge. The defective element should be replaced immediately, otherwise the bulbs will have to be changed frequently, fire or short circuit may occur.
You cannot use LED devices in chandeliers with closed shades, with the ceiling bulb placed downward. With this arrangement, heat accumulates, there is no cooling option.
Poor quality LED bulbs
One of the recommendations of electricians is not to buy devices for less than 120 rubles. Less expensive models are made without the possibility of cooling, stabilization, ballast capacitors and other protection methods, while they have a flimsy body. Although such devices "without everything" disappear from the market.
To minimize the consequences when working with cheap mechanisms, you can install a varistor - a special device that stabilizes the voltage in case of power surges. Usually, a device is used with a response level of about 470 V. Additional methods are to install a filter capacitor and a fuse on the board.
Rare factors provoking burnout of LED lamps
If the LED lamp burns out, there may be a lot of reasons. In addition to the main ones, there are non-obvious and more rare options. They are worth considering if the others did not fit.
Frequent on / off lamps
The inclusion of the LED light means the transfer of the flow of electricity through the smoothing capacitor. With frequent closing and opening of the circuit, one of the elements may burn out: a fuse, a conductive track.
It is not recommended to cross the circuit frequently - turn it on, turn it off. LED luminaires are economical, energy-saving, so an extra hour of work will cost less than a new light bulb.
Voltage transformer
Fuses and other protection systems are often lacking in budget models. Therefore, inexpensive devices fail even with a minimal power surge. The work is provided by special drivers - converters. Often, such mechanisms quickly break down, which leads to burnout of light bulbs.
Luminaires with a power of less than 12 volts are supplemented with electronic transformers. If several lamps do not work, you should first check the functionality of the fuses. Additionally, the presence of voltage at the output and the integrity of the LED mechanisms are checked.
Poor wiring quality
Even expensive LED lamps will not last many years if gross errors are made during installation. Self-installation can also be fraught with unpleasant consequences. If you need to replace several devices at once (chandeliers, sconces, lamps), it is better to invite a master. Pre-check the wiring for the integrity of the sections, change the faulty elements, eliminate twisted and bent parts.
What lamps will last a long time
Manufacturers are positioning LED bulbs as a more reliable and cost-effective alternative. A 100 W incandescent LED lamp in practice consumes no more than 10-12. Operating time - from 20 to 30 thousand hours in continuous mode. Thus, under favorable conditions, one light bulb will last for 12-14 years (calculation for residential premises).
An additional advantage is the absence of harmful chemical compounds (mercury and others). The disadvantage is the cost. LED lamps are an order of magnitude higher than Ilyich's bulbs (the minimum average price is 300 rubles). At the same time, the manufacturer is promised a full payback in 3-4 years.
To purchase a high-quality device, they pay attention to several points when buying:
- assembly - the condition of the body, parts;
- light weight - models made of thermoplastic weigh 100-120 grams;
- external radiator - must have an aluminum case, ribbed edges;
- diffuser - plastic accumulates more heat than glass;
- thermal paste - in budget models, the amount is less, which worsens the quality of heat dissipation (you can add, if the diffuser is removable, apply a thin layer to the inside).
To provide a sufficient amount of light in a room or other space, it is recommended to purchase spotlights. The peculiarity of LED lamps is in the narrow directivity of the illumination beam.
How to Extend the Life of LED Bulbs
Inexpensive devices quickly burn out near heat sources - heating destroys the main elements. Therefore, during installation, you should avoid proximity to heating elements, household appliances. In a room with a high temperature (for example, kitchens, baths), LED crystals are destroyed faster. You need to think about cooling and buy better quality devices. In this case, LEDs can be installed in conjunction with a stretch ceiling.
If an LED strip is used, an aluminum profile is chosen for fixing. This material will provide sufficient heat dissipation. The use of profiles from other compositions will cause the LEDs to burn out.
A power stabilization unit is additionally installed in the car to the tape. The resistor is not able to protect the luminaires from changes in the power of the on-board electrical computer. They buy bulbs of famous brands. It may take time to select a brand for a particular car - not all fit together.
If an LED light bulb burns out, you need to figure out what to do first. You can fix the 220V LED device yourself. The first safety rule is to de-energize the network. Then they disassemble the lamp, remove the light bulb. First, a visual inspection is carried out - the place of failure is visible to the naked eye. The burned-out element darkens, becomes covered with carbon deposits. If outwardly order, check the presence of voltage.
More and more users are switching to LED bulbs - energy-saving, reliable, with different glow options. An additional bonus is gradually decreasing prices. In order for the bulbs to serve for a long time, you must follow the requirements and rules. The savings can be substantial.
They buy LEDs in trusted stores, it is better to familiarize yourself with the reputation of the outlet and the manufacturer's brand in advance.
I bought three packs of LED lamps (10 pieces in a pack); two packs have been working for several years already, but they stopped working with one or one after the other, such a batch came across
The problem is in the cheaper drivers, poor heat dissipation from the crystals and the operating mode at the limit. It's all inside the lamp
Some kind of garbage ... I have been using LED lamps since they began to appear. My experience.
The main reasons for the failure:
- Faults and wiring defects - all wiring is in excellent condition.
- Defects of the chandelier - after the purchase I go through all the chandeliers, tk. really the quality of the GE. But the lamps are lit the same way.
- Low-quality LED lamps - and others are not. If the lamp costs more than 400 re, then it is not a fact that it is of high quality.
- Frequent switching on / off of lamps - how is it ?! Can't be turned on or off? Nonsense! I use it like regular lamps.
- Poor quality of electrical installation - close and close and does not depend on the price.
- Which lamps will last a long time - those with which you are lucky. The service life depends only on this.
- At the same time, the manufacturer is promised a full payback in 3-4 years. - a blatant lie. For 3-4 years, not only will they not pay off, but will also burn out a couple of times.
To purchase a high-quality device, they pay attention to several points when buying:
- assembly - the state of the body, parts - the appearance will not say anything
- light weight - models made of thermoplastic weigh 100-120 grams - do you suggest going to the store with weights? And where is the "correct weight" indicated for 14 rounds, and for 27 rounds, and how does the weight depend on the design?
- external radiator - must have an aluminum case, ribbed edges - aha, from 400-500 re!
- diffuser - plastic accumulates more heat than glass - the difference is so insignificant that it is not worth considering. I met a glass flask only in lamellas, but this is a separate class, and for the price too. By the way, they have neither a radiator nor thermal paste ...
- thermal grease - in budget models, the amount is less, which worsens the quality of heat dissipation (you can add, if the diffuser is removable, apply a thin layer to the inside). - and in the store, how to determine?!
At the moment, LED technologies are beneficial only to electricity suppliers to the end consumer - there is no need to modernize the cable system in order to provide power to new homes and shops.
No matter how much I thought, LED lamps NEVER pay off, at least for me.
After this article, I made one interesting conclusion - to use LED lamps you need:
- to be an electrician, a constructor-technologist of enclosures and a circuit engineer.
- first you need to redo all the wiring in the house, and not just in the apartment
- re-plan the lighting scheme so that the lamps do not overheat (lower them from the ceiling to the floor?!)
- go to electrical goods with a magnifying glass, X-ray, scales ...
- be sure to disassemble LED lamps immediately after purchase and redo
- and, most importantly, buy exceptionally expensive copies.
P.S. Didn't seem to have forgotten anything.
I almost completely agree with Arthur's comment. My experience with using such lamps suggests that it is advisable and possible, subject to some simple conditions:
1.buy lamps from trusted reliable manufacturers (price is NOT an indicator)
2. buy lamps in a store within walking distance from home, keep receipts from the purchase and do not hesitate to replace those that are out of order under warranty.
3. In my opinion, in most cases, the cause of failure is OVERHEATING. This is usually facilitated by the design of the lighting device. For example, a tightly closed plafond or a plafond in the form of a dome without holes for hot air to exit upward. As a result, we have insufficient heat dissipation from the lamp and, as a result, overheating with failure.
4. Sparking and wiring quality is, in my opinion, a rare and atypical case. If the state of the wiring is so deplorable that it sparks from energy-saving lamps, this is a direct and quick path to fires and failure of all wiring when trying to use any more powerful device.
The article is about nothing. I also bought expensive ones, immediately took 5 pieces for the chandelier, after a month they all started to smoke. True, they replaced without problems and apologized, in exchange they sent as many as 6 pieces, as they knew, one in a week ordered to live long. The wiring is excellent and the lamps are expensive, the chandelier is ventilated, and the shades are up. And here is a cheap Chinese 6 W lamp. it has been on for 6 years, though the LEDs are noticeably hooked…. You can't guess, it shines dimly, but it's a pity to throw it away, greedy))))
I installed an LED light bulb in the entrance. Has been working for 2.5 years.
I used to change ordinary light bulbs every 2-3 weeks.
The kitchen has 9 LED lamps (in the false ceiling).
On average, I change 1 light bulb per year. (general warranty 2 years).
Halogenki changed every month for 1 piece.
