Blown light bulbs : Cause and troubleshooting

problem of burnout light bulbs

Now for many pressing problem is too frequent burnout lamas incandescent galogenok, LEDs, etc.Causes: poor quality lamps, and various environmental factors.Very rarely they produce to the manufacturer resource, therefore it is necessary to understand why the bulbs burn out and possibly correct the situation.Affect the quality of consumer products is very difficult, so pay attention to external factors affecting the duration of the different lamps.

few reasons incandescent bulbs burn out and not only.Ways to address them

certain percentage of premature failure of the light source falls on the low-quality products, but most of these cases are not connected with themselves lamps.

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

• Needless to high voltage level in electrical circuits, houses and apartments. This is bad for the duration of the operation of lamps that can be explained by natural processes occurring inside the bulb.If the voltage measured by multimeter 220 displays not the standard, and for example, 236 V, which is within the approved rate deviations, but on a tungsten filament lamp enters its high voltage and temperature, which is typically about 2 0000S markedly increases.Because of this, the tungsten filament begins to evaporate much faster and deposit on the glass, which causes a significant darkening of the bulb.

cope with such a situation is possible in different ways.The easiest option - when buying such products to pay attention to the value of the operating voltage, which is indicated as on the box and on the lamp. Preference should be given to the light sources, which are designed for 230-240 V. Sometimes there are items with values ​​in the 235-245 V, which is much better suited. can go to energy-saving lamps , a job that boosted voltage (within the norm), it has no negative effect.To cope with this problem will help stabilizers voltage, as well as dimmers and defensive blocks.

• Defective cartridges and bad contacts in them. This is one of the main reasons why the bulbs burn out.Now most of the cartridges are made of plastic, and it has not always good quality.Their exploitation is mainly limited to the use of lamps with power up to 40W.Failure to follow this simple rule often leads to cracking or fading cartridge.But even when it is subject during operation contacts oxidize them, which leads to overheating of the lamps and their premature failure.

Here you can find the answer to many buyers, the question: "Why burn out bulb in the chandelier, andonly one? ".If there is a problem, but still accompanied by recurring cod, changing the brightness of the burning, then with high probability it can be concluded that the reason for the bad contacts cartridges.Council to use ceramic cartridges is not currently relevant.Therefore follow the status of the contact and, if necessary, we clean them. burnt cartridges must be replaced, and buy a new lamp is better.

• Needless to frequent switching of lamps. Sometimes, trying to save on electricity consumption, incandescent permanently shut down to just a few minutes later to ignite them again.Each time the amount of current that passes through the filament is much greater than when it is in working condition.This means that frequent switching is one of the causes of burnout tungsten filament.To conserve better to install energy-saving and other modern types of lamps.However, the reason why lamps burn saving, is also unnecessarily frequent their network connection, including a periodic flashes when the circuit breaker having a backlight.

• problems with the switch. If he had exhausted their resources, then it should be easy to replace, and then the situation where often burn out bulbs, will be fixed.This procedure is advisable to combine with the installation of a dimmer, which will protect the lamp from the current jump when they turn on and change the brightness of the light as desired.In case, if the switch sparks, or there was a noticeable soot on pins or wires suitable for them, such a product is to be immediately replaced.

• Influence of mechanical stress, vibration and temperature.On incandescent any mechanical impacts and vibration take their toll, leading to burn them.In such places is better to use other light sources such as LEDs. Low temperatures also lead to the fact that too often burn out bulb. When in the zone of their operating temperature is markedly reduced, followed by decreases, and the resistance of the filament.At the same time increasing the value of starting current, which is the cause of a blown bulb.

• Another answer to the question: «Why burn out light bulb?" - Because of incorrectly chosen scheme of their connection. Somehow option chosen most often when each lamp is connected to a single wire, and which accounts for the total load.If for any reason, the first lamp, counting from the junction box, oxidized contacts within the cartridge, it starts a chain reaction in which the overheated wire extending from the chuck, and then places the common wire connections.Then do not avoid their oxidation, which is exacerbated by a much greater load these lamps, which means that the resistance value increases and cause voltage drops, which is one of the causes of burnout different types of lamps.

• incorrect or not very good quality connection cables in the chandelier, the junction box andetc. In such circumstances often burn LED bulb, as well as halogen, fluorescent, and others. It is very common option when the connection is used for twisting.Then the inevitable oxidation of the wires, as well as the appearance of eddy currents.Correct the situation is not difficult - just use the terminal blocks or other modern methods of connecting wires.

Conclusion

were listed the main problems causing burnout of different types of lamps and their solutions.If you doubt that you can deal with the problem themselves, use the services of professionals, or at least consult with them, setting out all the features of the situation.
