What is the reason why light bulbs often burn out?
1. So voltage and current are the main reasons why the light bulb often breaks down. In addition, the current product quality is uneven, it is possible that what you buy is a shoddy light bulb. Or you can buy a product that does not match the working voltage of the power supply, which can easily lead to burnout of the light bulb.
2, the voltage in the home is too high, the voltage is too high, the light bulb will not only burn out, but also explode and cause fire, the hidden danger of safety is still relatively large, if the voltage at home is unstable, be sure to invite a professional electrician to repair it. Before repairing the voltage, you must turn off all the electric valves at home.
3. The main reason why the light bulb often burns out is the failure of the voltage regulator, which makes the output voltage of the generator too high or the ampere number of the light fuse incorrect, which can not protect the lighting system when the line is short-circuited. 1) check whether the generating capacity of the generator is normal, and replace the generator regulator if the voltage is too high.
4. the reason why the light bulb is often burnt out. It’s because the voltage is unstable. The voltage is sometimes high and sometimes low. When the voltage is high. The current is high. The current is high. It’s easy to burn out the filament. After Deng Si burned out. The light bulb goes off. To keep the light bulb from burning out. Then install a voltage regulator.
5. If the ground wire and zero wire are not connected well, it will be easy to burn the lights. Another is whether the quality of the lamp you buy is good or not, buy some good brand lamps to replace. If it’s all the same problem, check to see if the voltage at home is unstable. It is easy to burn these lights if the voltage is unstable for a long time.
Is there something wrong with the circuit when the light bulb keeps burning out?
1. So voltage and current are the main reasons why the light bulb often breaks down. In addition, the current product quality is uneven, it is possible that what you buy is a shoddy light bulb. Or you can buy a product that does not match the working voltage of the power supply, which can easily lead to burnout of the light bulb.
2, the lamp at home is always burnt out, in addition to considering the cause of the high voltage, we also need to consider whether the quality of the bulb, many aspects to find the reason, in order to better solve the problem.
3. It should be caused by poor contact of zero line. It is recommended that you first measure the voltage to make sure that the voltage is normal. If the voltage stability damages the lamp, it means that the ballast and the lamp do not match, or the quality is too poor.
There are only three reasons why incandescent bulbs often burn out: the quality of the bulbs is poor. The power supply voltage of the district is high and unstable. You can consult your neighbors to see if the problem of high voltage instability can be solved. The bulb is turned on and off frequently, which greatly shortens the service life of the bulb.
5. The electric light at home will always burn out, which should be caused by poor contact with zero wire. It is recommended that you first measure the voltage to make sure that the voltage is normal, and then temporarily connect a zero wire from the outside, connect some lights, and see the results. In this way, the zero line can be excluded first.

There are three main reasons why incandescent bulbs often burn out: the incandescent bulbs commonly used are of poor quality. If you live in a neighborhood where the power supply voltage is high, there is often instability. It will also greatly reduce the useful life of the light bulb.
