What s the matter with the bulb always burning out, is there a problem with the circuit when the bul

1. The quality of the bulb. When buying bulbs, you can't just pay attention to **, you must pay attention to quality, bad quality bulbs are easy to burn out, it is recommended that you buy Philips bulbs, Philips has been an old brand in China for decades, the quality of bulbs is guaranteed, Philips bulbs have a very long service life, and they will definitely not burn out.

2. The voltage at home is too high and the voltage is unstable. If the voltage is too high, the bulb will not only burn out, but also cause a disaster, and the potential safety hazards are relatively large, if the voltage at home is unstable, you must ask a professional electrician to repair it, and before repairing the voltage, you must close all the electric valves at home.

3. The humidity near the bulb is relatively large. The bulb is surrounded by moisture, which will cause a short circuit in the wires and affect the normal use of the bulb, it is best to install the bulb in a dry place so that the bulb can be used normally.

4. Turn on and off the bulb frequently. Frequent opening and closing of the bulb, the filament is repeatedly hot and cold, it will burn out, if the filament is uneven and hot will also lead to the lampshade**, be sure to remind the children at home can not play with the bulb casually, the lampshade** is still more dangerous.

The quality of the bulb: the purchase of bulbs can not only focus on the first, but also pay attention to the quality. The voltage in the home is too high:

If the voltage is too high, the bulb will burn out. High humidity near the bulb: Moisture around the bulb can cause short circuits in the wires and affect the normal use of the bulb.

Turn the bulb on and off frequently: The filament is repeatedly hot and cold, and it will burn out.

There may be an electrical problem that causes the bulb to burn out frequently. Here are some possible reasons:

1.Excessive load on the circuit: If the circuit where the bulb is located is overloaded, it will cause the circuit to generate too high voltage and current, which will cause the bulb to burn out.

2.Too many branches in the circuit: If there are too many branches in the circuit, it is easy to cause the bulb to burn out.

3.The power supply voltage is too high: If the power supply voltage is too high, it can also cause the bulb to burn out.

4.Damaged Lamp Holder: If the lamp holder is damaged, it may result in a poor connection between the bulb and the circuit, which can cause the bulb to burn out.

If your bulb burns out frequently, it is recommended to check the above causes, or ask a professional to check and repair the circuit.

This is not necessarily a problem with the circuit.

If all other appliances are working properly, there may be a problem with the quality of the bulb.

If you can, it is advisable to use LED lights instead. Compared to ordinary light bulbs, it is power-saving and durable.

There are several main reasons:

1.At present, some manufacturers on the market have poor production quality and are easy to burn out, which is a common phenomenon.

In view of this situation, we must choose regular big brand bulbs with guaranteed quality when buying bulbs, first, the quality will be easy to use for a long time. Then there is high security, and some three-no products on the market are easy to cause potential safety hazards.

2.The voltage may be high or unstable, exceeding the rated voltage of the bulb.

Solution: 1) We can connect a bulb in series to divide the pressure.

2) Install the voltage regulator. This is an effective way to solve voltage instability. With the installation of a voltage regulator, you can safely and stably use electricity at any time and anywhere. It is important to note that it is best to seek professional help when purchasing and installing a voltage regulator.

3) Install UPS. If you have the conditions, you can use a UPS to stabilize the voltage. UPS is also called uninterruptible power supply, it not only has the advantage of continuing to use after power failure, but more importantly, it can stabilize the voltage very effectively.

Because its power supply is output through a built-in power supply. If you use a UPS, the voltage becomes very smooth.

3.The bulb cannot be turned on and off frequently, and sometimes children play with it, and it is easy to burn out the bulb due to the repeated cold and heat of the filament.

The reason why light bulbs are always bad :

1. It should be caused by poor contact with the zero line.

2. It is recommended to measure the voltage first and confirm whether the voltage is normal.

3. Temporarily connect a zero line from the outside to come in, connect the light, and see the result.

Question 1: What is the reason why the light bulb often burns? 1.Burning light bulbs is more related to environmental factors, and places with high humidity are easier to burn.

2.The bulb is not in good contact and is easy to burn.

3.In contrast, the greater the power than the power is easy to burn.

4.Others, such as the lights that are frequently switched on and off, such as the staircase walkway, are prone to burning.

5.Then there is something to do with quality.

Question 2: What is the reason why the light bulb is always burned Reason:

1.The voltage is high, and the voltage from the substation is unstable;

2.The quality of the bulb is poor, when the bulb is made, there is air in the bubble body, and the thickness of the tungsten filament is uneven;

3.The power cord is loose, the contact is poor, or the power cord is aging, and the neutral wire is live;

4.The bulb does not take effective protective measures, and the outside temperature and the temperature inside the bulb have a large difference, and the bubble body cracks;

5.If it is a bulb LED or energy-saving lamp, it will have poor heat dissipation effect and aging of electronic components at the root of the lamp body after long-term use;

6.Frequent and frequent dismantling can also lead to a shorter luminaire life.

Question 3: What is the reason why the bulb often burns The voltage is unstable or the quality of the lamp is problematic, it is recommended to change the bulb of another brand.

Question 4: What is the reason why the light bulb often breaks? The first can be caused by unstable voltage.

Second, it may be a problem with the line, and the joints and switches have poor connections.

Third, because it is winter, the temperature may be relatively low, the temperature of the filament before the light is not turned on and the temperature after the light is turned on is too different, it is easy to burn the filament, when the light is turned on, quickly turn on the off switch, do a preheating, so that the probability of burning is smaller.

Question 5: What is the reason why the bulb is always burned The wattage is too large, so try it with a small wattage.

Question 6: What is the reason why the car often burns the bulb First, it means that the quality of the car's bulb is not good.

Second, the car's light bulb is used too often, and in many cases the lights have to be turned on.

Third, it is easy to break the lights when driving too many times.

Fourth, you can choose some bulbs to use, such as Osram, Philips, etc.

Fifth, if you use a better brand of bulb and still burn out frequently, it is a circuit problem.

Sixth, it is recommended that the 4S shop with the lights on the car go to test the specific reason.
