Is there any bad effect on turning on and off the lamp several times in a short period of time?

In this way, the lamp will break, and the switch inside is set by the principle of resistance.

If you keep switching, the contact between the contact resistor sheets will not work. Not really, don't worry.

Frequent switching of the lamp, the current in the filament back and forth, will damage the resistance wire, resulting in a reduction in the service life of the lamp, which will seriously lead to a short circuit, that is, burn out the lamp.

Affect the service life of the lamp, the quality assurance of the lamp should not be **, but if the current is unstable, this possibility is not ruled out.

**No, but it will reduce the life of the lamp.

No**, but it will break the bulb.

The bulb will heat up, the filament will break, and persuade your little cousin that it's not good to play like this.

No, but the bulbs will break faster.

Yes, this will shorten the life of the lamp.

For table lamps, and lamps will affect their life, if the quality of the lamp is qualified, it will not happen.

**？No, you often turn on and off, you don't feel tired, the desk lamp will feel tired, do you say it will have an impact? It's already giving you face if it doesn't strike.

The lamp will burn out during repeated charging.

Reduces the life of the lamp and makes it easy to flash the bulb.

The bulb burns out easily.

It is estimated that it also has his lifespan, such as 1w times, maybe she will be damaged.

The lamp will break down very quickly.

This reduces the life of the lamp.

No.

Lamps, lighting supplies, generally refer to appliances that can be illuminated. In ancient times, humans used torches for lighting, and later there were candles and oil lamps. In ancient times, a "candle" was a torch made of flammable materials, and the torch that had been lit was called a candle. The piles of fine grass and branches that are placed on the ground to be lit are called fires, and those that are placed outside the door are called large candles, and those that are placed inside the door are called court fires.

Where there is light, there is human civilization. Tens of thousands of years ago, humans already knew how to use natural fire to protect themselves from the cold, barbecue and light. More than 3,000 years ago, human beings began to use simple lamps to carry fire candles and write the history of civilization.

From rough stone lamps to bronze lamps, ceramic lamps to modern electric lamps, the historical changes of lamps and lanterns have marked a profound imprint of the times, and at the same time, they are also the epitome of social economy and culture.

Before the advent of electric light, the common lighting tool used by people was kerosene lamps or gas lamps. Because they burn kerosene or gas, they have a strong black smoke and a pungent odor, and they are inconvenient because they need to be fueled and the shades are often scrubbed. What's more serious is that this kind of lamp is easy to cause disasters and cause catastrophes.

For many years, many scientists have tried their best to invent a safe and convenient electric light.

At the beginning of the 19th century, a British chemist used 2,000 batteries and two charcoal rods to make the world's first arc lamp. But this light is too strong to be installed on streets or squares, and cannot be used by ordinary households. Countless scientists have racked their brains to create an inexpensive, high-quality, and long-lasting household electric light.

Hello. Frequent switching will affect the life of the lamp. If the lamp cannot be started frequently, the number of frequent starts, the life of the lamp will be shortened compared to the rated value.

Each activation is equivalent to two hours of ignition. Because every time it is started, the two cathodes will be subjected to a high-voltage pulse impact, so that the consumption of electron emission material on the cathode increases, and when the electron emission material on the filament is exhausted, the lamp tube will be scrapped. Therefore, where possible, the number of times the lamp is switched on and off is minimized to prolong the life of the lamp.

The switch doesn't like you to press it all the time.

Summary. Hello dear, The following answers have been made to your questions, which is like this, and I have helped you sort it out!

Hello dear. This is because when the light is turned on, there is an impulse current, which is much larger than the normal value, and the continuous switching of the light in a short period of time is to continuously let it withstand the impact, so it is easy to break.

Turning on and off the light continuously in a short period of time, why is the light easy to break.

In our school, the lights were turned on, and some people turned off the lights, and we turned on the lights, but then they turned them off again, and we turned on the lights again, and they didn't turn on, what happened?

Are you there. Hello dear.

Hello dear, your situation is that the light bulb has burned out and flashed.

The life of incandescent lamps is mainly related to the number of switching times, and the life of energy-saving lamps is mainly related to the service time.
