Why do the lights break down shortly after they turn on?

The reasons why the more common lamps are broken in a short time after they are connected are: 1. The rated voltage of the lamp.

There is a large difference with the rated voltage of the power supply (wire), and the high voltage directly breaks down the low-voltage rated lamp: 2. The lamp is dedicated to DC, and the wiring is alternating current.

In the case of wire power supply, alternating current is relatively large, it will directly break the lamp.

This may be a problem with the circuit, such as an unstable voltage. This makes it easy for the lights to be damaged.

If the voltage is relatively stable, it may be that the bulb is not well sealed, there is air leakage, or the filament quality is not good.

The electric checkout line is not long, and then it breaks, it may be that the bulb of this electric light has a quality problem, or it may be that the current is too large, which causes the bulb to be damaged.

It means that the voltage is too high or there is a problem with the quality of the bulb, otherwise it is impossible.

The light is connected to the line and the light is broken soon after, maybe the voltage is too high, the fuse of the light bulb is burned, maybe the quality of the light bulb is not up to par!

It may be that there is some malfunction in the electric light, and when it is on, it is easy to cause a short circuit inside, so it burns out.

The bulb has quality problems; The power supply voltage and current are unstable and too high; AC and DC power are used in the wrong ......

If the light in your home is connected, the time when it is on after smoking will not be broken, it is because the quality of the light is not particularly good, and maybe the voltage in your home is not suitable will also cause damage to the bulb.

I think it's probably because of the voltage, or maybe it's the power.

Four reasons: 1. If the power is turned on and does not light up, and then suddenly lights up in a few seconds, this situation is a ballast failure. 2. If the light flashes after the power is turned on, it means that there is a problem with the starter (that is, the bubble jump).

3. Then there is the broken lamp. 4. Poor line contact.

As the temperature of the lamp changes, the resistance value in the lamp becomes smaller and smaller, and the lamp becomes brighter and brighter.

Converter problem: Do you turn the light on and on quickly?

The lights don't turn on when they are turned on, and they don't turn on for a while for the following reasons:

1. If the light does not light up after the power is turned on, and suddenly turns on in a few seconds, this situation is a ballast failure.

2. If the light flashes after the power is turned on, it means that there is a problem with the starter (that is, the bubble jump).

3. Then there is the broken lamp.

4. Let the round liquid line be in poor contact.

It is recommended to replace a driving power supply with the same parameters on this lamp first, and replace a driving power supply if it can emit light normally; If the power supply is replaced, it is still not possible, and the light source needs to be replaced.

Summary. It mainly depends on the heat dissipation conditions of the bulb. It doesn't matter if the heat dissipation is good (it ensures that the temperature of nearby objects is not dangerous during continuous operation).

If the heat dissipation is not good, there will be a problem, and it may cause disasters (combustibles or wire insulation burning nearby), burning filaments, etc.

Is it okay if the lights stay on for three days?

Basically, there is no problem.

Is it okay to have a bathroom light that is commonly used at home and is on all the time?

Try not to spend so many days and electricity.

The owner went out and forgot to close it when he left. It doesn't matter if it's just that it costs electricity, it's just that I'm afraid of a fire.

No, it won't. As soon as there is a leak, the direct air switch trips.

In the lamp circuit, the resistance of the wire is much smaller than that of the filament, and the same current flowing through the wire basically does not heat up, but when it flows through the filament with greater resistance, it heats up, and when the temperature is relatively high, the filament emits light. This is the principle of incandescent lamps.

Electric lights, that is, artificial lighting appliances that use electricity as an energy source, can convert electricity into light, which has greatly promoted the progress of human civilization. Common types of electric lamps are incandescent lamps, fluorescent lamps, LED lamps, etc.

The earliest practical electric lamp was the incandescent lamp, but long before the birth of the incandescent lamp, the Englishman Humphrey David used 2000 batteries and two carbon rods to make the arc lamp, but the arc lamp was too bright, produced too much heat and was not durable, and it could not be used in ordinary places.

Modern light bulbs use an inert gas, usually argon, which greatly reduces this loss of tungsten. When a tungsten atom evaporates, it collides with an argon atom and since the noble gas usually does not react with other elements, there is no combustion reaction. Cheap and easy to use, the bulb has proven to be a great success.

Light bulbs are still the most popular lighting choice for indoors. But it will eventually give way to more advanced technology because it is not energy efficient enough. Most of the energy emitted by incandescent light bulbs is emitted by thermal-infrared visible photons – only about 10% of the light produced is in the visible spectrum.

This wastes a lot of electricity. Warm light sources, such as fluorescent and LED lamps, do not waste Dali's energy to generate heat and emit most of the visible light. As a result, they slowly replace the bulbs.

Because there is an electric current flowing through the tungsten wire and the resistance of the tungsten wire is very large, it generates light.

It should be caused by poor contact with the zero line. It is recommended that you measure the voltage first to confirm whether the voltage is normal. If the voltage is stable and the lamp is damaged, it means that the ballast and the lamp do not match, or the quality is too poor.

The electric lights at home will always burn out, which should be caused by poor contact with the neutral line. It is recommended that you measure the voltage first to confirm whether the voltage is normal, and then, temporarily connect a neutral wire from the outside to come in, connect some lights, and see the result. This allows the zero line to be excluded first.

In addition, when the two metals are put together, over time, there will be a chemical reaction in the contact part, so when the light is turned on, there will be a breakdown effect, and then the bulb will be damaged.

These problems of yours should be caused by poor contact with the zero line. It is recommended that you measure the voltage first to confirm whether the voltage is normal (if it is not a separate wiring, it is estimated that there should be no problem with the voltage, otherwise the neighbor will be like this, but it is better to check it), and then, temporarily connect a zero wire from the outside, connect some lights, and see the results. This is the only way to eliminate the zero line first.

1.You're not quite right. Burning an insurance and burning a lamp are two completely different things.

2.The only reason for burning the fuse is overcurrent (caused by heavy load or short circuit), and the only reason for burning the lamp is in the residential electricity consumption, which is too high voltage (it may be connected to the line voltage of 380V, or another short circuit relative to the neutral line).

3.2 square wires It is no problem to take 5 A current, and electrical appliances below 1000 W can be used casually (total power).

4.Judging from the situation of the lamp you described, it should be a problem with the zero line, and eighty percent of the three phases are short-circuited to the zero line.

The lamp will always burn out, which may be caused by too high voltage, which is related to your total zero line, and the lamp problem can be replaced one by one with good parts.

If there is a problem with the wiring, it is best to find an electrician to check it.

There is a problem with the zero line, the voltage is low or the electricity is high (the factory voltage should be high), the pass rate of China's lamps is 60%, and it is easy to break. It is also related to the poor contact of the lamp head, and the lamp and rectifier are changed together.

It may be that the current is unstable, and it is better to install a capacitor.
