Ilyich’s classic bulbs were more often replaced with modern LED lamps. LEDs are more reliable, they have several glow options (daytime, cold, warm, other). The lamp life is several times higher than that of classic ones - 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 causes of 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 for a long time, expensive, is not always possible.
"The human factor" - the mistakes of electricians, builders, other masters are not uncommon. Incorrect calculation of the required voltage, poor connection of the contacts, the selection of inappropriate elements - all this leads to network sparking, failures, disconnections and other problems.
“Wrong” lighting fixtures (sconces, chandeliers, lighting fixtures) are another reason for LEDs to burn out continuously. About a third of the consumed voltage is spent on lighting, the remaining 2/3 are transformed into heat. Therefore, when developing devices, it is necessary to take into account the heating of crystals and provide for the possibility of timely cooling.
The main advice is to use medium power lamps (about 5-7 watts). They produce less heat, which means they heat up less and last longer. Instead of buying 12-watt lamps, they recommend buying 4-watt lamps.
To understand why LED bulbs burn out, often only a professional electrician can.
Faults and wiring defects
LEDs burn out with frequent surges and voltage drops. Problems arise on power lines, during a thunderstorm, directly in the room. Timely checking the integrity of the wires will help to avoid unforeseen breakdowns and reduce the burnout frequency of LED-lamps.
LED lamps do not work well under low voltage conditions. Check the quality of the connections in the junction box, eliminate twists and kinks. Old switches and blocks can also cause premature burnout of energy-saving light bulbs.
Check the chandelier, identify defects
Chandeliers have a simple structure and the main "problem" place - the cartridge. Symptoms:
- excessive heat;
- sparking;
- blackening and soot.
If bulbs in one place often burn out in a multi-lamp chandelier, then there are problems with the cartridge. The defective element should be replaced immediately; otherwise, the bulbs will have to be changed frequently; a fire or short circuit may occur.
You cannot use LED devices in chandeliers with closed shades, with the ceiling bulb placed down. With this arrangement, heat accumulates, there is no cooling capacity.
Poor LED lights
One of the recommendations of electricians is not to buy devices cheaper than 120 rubles. Less expensive models are made without the possibility of cooling, stabilization, ballast capacitors and other methods of protection, while having 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 voltage during power surges. Usually they use a device with a trip level of about 470 V. Additional methods are to install a filter capacitor and a fuse on the board.
Rare factors that cause LED lamps to burn out
If the LED lamp burns out, there may be a lot of reasons. In addition to the main, there are non-obvious and rarer options. They should be considered if the others did not fit.
Frequent on / off lamp
Turning on the LED bulb means transferring 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 path.
It is not recommended to often bridge the circuit - turn it on, off. LED-lamps are economical, energy-saving, so an extra hour of work will cost less than a new bulb.
Voltage transformer
Budget models often lack fuses and other protection systems. Therefore, low-cost devices fail even with minimal power surges. Work is provided by special drivers - converters. Often, such mechanisms break down quickly, which leads to burnout of bulbs.
Luminaires with a capacity of less than 12 volts are supplemented by electronic transformers. If several lamps do not work, you should first check the operation 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 for 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.
Which lamps will last a long time
Manufacturers are positioning LED bulbs as a more reliable and profitable alternative. A 100-watt LED lamp in practice consumes no more than 10-12. Operating time - from 20 to 30 thousand hours in a continuous mode. Thus, under favorable conditions, one light bulb is enough 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, when buying, pay attention to several points:
- assembly - condition of the housing, parts;
- low weight - models made of thermoplastic weigh 100-120 grams;
- external radiator - must have an aluminum body, ribbed edges;
- diffuser - plastic accumulates more heat than glass;
- thermal grease - in budget models the quantity is less, which affects 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-luminaires in a narrow focus beam.
How to extend the life of LED lamps
Inexpensive devices quickly burn out near heat sources - heating disables the basic elements. Therefore, when installing, avoid proximity to heating elements, household appliances.In a room with a high temperature (for example, kitchens, baths), LED crystals are destroyed faster. It is necessary to think over cooling and to get devices of the best quality. In this case, the 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 lead to burnout of the LEDs.
In the car to the tape additionally install a power supply stabilization unit. The resistor is not able to secure the luminaires from changes in the power of the onboard electrical computer. Buy light bulbs of famous brands. To pick a brand for a particular car, it may take time - not all are combined.
If the LED bulb burns out, you need to understand what to do first. You can fix the 220V LED device yourself. The first security rule is to power off the network. Then 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 burnt out element darkens, becomes covered with soot. If outwardly order, check for voltage.
More and more users are switching to LED bulbs - energy-saving, reliable, with different lighting options. An additional bonus is gradually decreasing prices. In order for the bulbs to serve for a long time, it is necessary to follow the requirements and rules. Savings can be substantial.
Buy LEDs in trusted stores, it is better to familiarize yourself with the reputation of the outlet and brand of the manufacturer in advance.
