Top 5 causes of light bulb burnout
The lighting of any house or apartment involves the presence of light bulbs. Due to various circumstances, the elements may burn out, which becomes the reason for their replacement. Below are the main causes of breakdowns and what to do if light bulbs often burn out.
Why does the lamp burn out
This happens for a number of reasons. It is worth considering common cases due to various network or environmental factors.
Increased mains voltage
For proper operation, any household light bulb requires a stable voltage of 220 V. However, this indicator is not always supported on the network. Even regulatory documents allow a deviation from the norm by 10% in any direction. Bulbs, on the other hand, cannot cope with such differences, which leads to accelerated degradation of the lighting element.
Even a one percent voltage deviation from the norm leads to a reduction in the overall life of the device by 14%.
You can determine the malfunction of an incandescent lamp simply by physically examining the device. Power surges or exceeding the set values \u200b\u200blead to overheating of the filament and its breakage. This is due to the evaporation of the tungsten coating of the filament.
A dark coating will be visible on the bulb of a burnt out lamp. To check, screw the light bulb into a serviceable cartridge of another lamp.
You can solve the problem by installing a new lamp with a high voltage limit. You can also use protective blocks that provide soft turn on light. An additional voltage stabilizer in the electrical circuit will also help smooth out surges and ensure uniform power supply to the light source. You should not dismiss the possibility at any time to switch to another type of lamp, devoid of such shortcomings.

Too frequent connection
In some cases, the lamps burn unstably or fail due to frequent switching on and off. Before turning on, the filament has room temperature, and immediately after the circuit is closed, a current is supplied to it, quickly heating the element to high temperatures. Frequent drops inevitably lead to degradation of the material and its failure.
Additional equipment for a smooth start will help to cope with this problem. The devices gradually increase the voltage applied to the thread, preventing sudden surges.
Problematic cartridge contacts
A cartridge is used to transfer electricity from the network to the light bulb. Any of its malfunctions lead to a breakdown in contact and unstable operation of the lighting device.Everything can start with a slight buzz or crackling, indicating a violation of the insulation.
Inspect the cartridge, it is possible that deposits have formed on the contacts. It needs to be cleaned up. Contacts must be pressed with an insulated tool to ensure proper connection of the components. If the cartridge is seriously damaged or deformed, it is advisable to replace it entirely.
Most modern plastic and ceramic cartridges are designed for continuous operation at a power of no more than 60 watts. This means that lighting elements must be selected with appropriate indicators. Exceeding will lead to unpleasant consequences.
Switch malfunctions
Long-term operation of the circuit can lead to wear of not only the lamp, but also the switch. In this case, the contacts inside the switch will periodically burn out and cause the lamp to flash. Subsequently, flashing will lead to a complete burnout of the element.
If the light bulb burned out when turned on, then there is a high probability of a problem in the switch. It is recommended to disassemble, carefully examine and, if necessary, replace. To prevent the problem from recurring, it is desirable to integrate a dimmer into the electrical circuit.
Poor wire connection
The fault may also lie in the wiring of the apartment. In this case, you will have to conduct a complete diagnosis of the connections in the shield. It is best to entrust the procedure to specialists, since it is quite dangerous and requires certain skills.
It will not be superfluous to make a calculation of the power of all electrical appliances connected to the network. If the allowable power is not enough, you must either reduce the number of connections or replace the wiring.
What to do if light bulbs burn out quickly
In most cases, lamps burn out due to violations by users of the rules for operating networks. Also, any mechanical influences reduce the life of the light source.
The best solution would be to replace conventional sources with modern LED lamps, which have increased resistance to voltage drops, vibrations, as well as temperature operating conditions.
If there is high humidity or a specific temperature in the room with the lamp, then it is necessary to select a device with an appropriate level of protection against such influences. Usually this information is indicated by the manufacturer on the packaging.
Preventive actions
To avoid premature failure of the lamp, it is necessary to connect the device in accordance with all the rules, equip the network with stabilizers, and follow the operating recommendations. Methods for extending the life of light bulbs deserve special consideration.
Increasing bulb life
If the cause of the burnout is an excess of the supply voltage, it is necessary to measure the corresponding indicators in the network. It is desirable to carry out diagnostics three times a day with the identification of the greatest value. It is he who must be taken as a worker for a particular apartment. The indicator of the lamp indicated on the flask must correspond to this voltage. On sale you can find elements with ranges of 215-235 V, 220-230 V and 230-240 V.
Minimizing vibration and shock will help increase product life. If the lamp still has to be moved from one place to another often, it is better to choose a low-voltage light bulb with a short incandescent spiral.
The presence in the chandelier for several light bulbs of one constantly burning source indicates a malfunction in the cartridge. It is necessary to carefully check the device for outgoing contacts. They need to be cleaned of soot and tightened.
Increasingly, electricians are installing special diodes in the circuit in front of the lamp, which increase the life of the system without reducing the quality of lighting. If you also connect a resistor in series with the diode, the light source will work for many years.
