Burnout of incandescent lamps: causes and solutions

The problem of burning incandescent bulbs

Now for many, the problem of too frequent burnout of incandescent lamps, halogens, LEDs, etc. is actual. Causes: poor quality of lamps and various external factors. Very rarely they produce the claimed resource by the manufacturers, so we need to understand why the bulbs burn out and, if possible, correct the situation. It is very difficult to influence the quality of products on the part of consumers, so we will pay attention to external factors affecting the duration of operation of different lamps.

Several causes of burnout of incandescent lamps and not only. Ways to eliminate them

A certain percentage of premature failure of such light sources falls on products of poor quality, but most of these cases are not associated with the lamps themselves.

There are several reasons why light bulbs often burn out, among them:

• Unnecessarily high voltage level in the electrical circuits of houses and apartments. This is bad for the duration of the operation of the lamps, which is understandable by the physical processes taking place inside the bulb. If the voltage measured by the multimeter shows not standard 220V, but for example, 236V, which fits into the norm of the approved deviations, but the tungsten filament of the incandescent lamp receives an increased voltage and its temperature, which is usually about 2 0000C, increases noticeably. Because of this, the tungsten filament begins to evaporate much faster and settle on the glass, which causes a significant darkening of the bulb.

There are many ways to cope with this situation. The simplest version - when buying such products, pay attention to the value of the operating voltage, which is indicated both on the box and on the lamp itself. Preference should be given to light sources that are designed for 230-240 V. Sometimes there are products with values ​​of 235-245 V, which are much better. It is possible for to switch to energy-saving lamps , for which the increased voltage( within the limits of the standard), does not have a negative effect. voltage regulators , as well as dimmers and protection units will help with this problem.

• Defective cartridges and bad contacts in them. This is one of the main reasons why light bulbs burn out. Now most of the cartridges are made of plastic, and not always it has good quality. Their operation is mainly limited to the use of lamps with a power of up to 40W.Failure to comply with this simple rule very often leads to cracking or burnout of the cartridge. But even if it is observed during operation, contacts in them are oxidized, and this leads to overheating of the lamps and premature failure of them.

Here you can find the answer to the question that interests many buyers: "Why do bulbs burn out in a chandelier, and only in one?"If there is such a problem, moreover, it is accompanied by periodic cracks, a change in the brightness of the combustion, then with a high degree of probability it can be concluded that the is the cause in the bad contacts of the cartridges. The advice to use ceramic cartridges is not currently relevant. Therefore, monitor the status of the contacts and, if necessary, clean them. Burned-up cartridges should be replaced, but it is better to buy a new lamp.

• Unnecessary frequent switching of lamps. Sometimes, trying to save on power consumption, incandescent lamps are constantly turned off so that after a few minutes they can be ignited again. At each switch-on, the current that passes through the filament is much larger than when it is in working order. This means that the frequent inclusion is one of the reasons for the burning of the tungsten filament .To save, it is better to install energy-saving or other modern types of lamps. However, the reason that the energy-saving lamps burn out is also their excessive frequent connection to the network, including in the form of periodic flashes with the light switch disconnected.

• Problems with the switch. If it has exhausted its resource, then it should be simply replaced and then the situation when the bulbs often burn out will be corrected. This procedure is advisable to combine with the installation of a dimmer, which will protect the lamps from a surge of current when they turn on and change the brightness of the light as desired. In the case of , if the switch is sparking, or there is a noticeable build-up on the contacts or suitable wires, then such a product should be replaced immediately.

• Influence of mechanical influences, vibration and temperature. For incandescent lamps, any mechanical influences, as well as vibration, have a detrimental effect, resulting in their burning out. In such places it is better to use other light sources, for example, LEDs. Low temperatures also lead to the fact that bulbs burn too often. When the temperature drops noticeably in the operating zone, the resistance of the filament is also reduced. At the same time, the values ​​of the starting current increase, which is the reason for the lamp burnout.

• Another answer to the question: "Why are the bulbs burnt out?" - because of the wrong connection scheme. For some reason, most often choose the option, when each lamp is connected to a single wire, which accounts for the total load. In case, for any reason, on the first lamp, if you count from the junction box, the contacts inside the cartridge are oxidized, then a chain reaction begins, at which the wires leaving the cartridge, and then the connections with the common wire, overheat. Further, their oxidation can not be avoided, which is aggravated by a significantly higher load of the next luminaires, which means that the resistance value increases and voltage drops occur, which is one of the reasons for the burnout of different types of lamps.

• Incorrect or poor quality connection of wires in a chandelier, junction box, etc. Under these circumstances, LED lamps, as well as halogen, luminescent lamps, etc., quite often burn out. A very common variant is when twisting is used for the connection. Then the oxidation of the wires is inevitable, as well as the appearance of eddy currents. To fix the situation is not so difficult - simply use terminal blocks or other modern methods of connecting wires.

Conclusion

The main problems causing burning of different types of lamps and ways of their elimination were listed. In case you doubt that you can cope with the problem yourself, use the services of professionals, or at least consult them, outlining all the specifics of the situation.
