The light bulb often breaks down. What is the reason?

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

In view of this situation, when we buy light bulbs, we must choose regular big brand light bulbs with guaranteed quality. First, the quality will last for a long time. Then there is high security, and some "three noes" products on the market can easily lead to security risks.

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

Solution:

(1) We can divide the voltage by connecting a light bulb in series.

(2) Install the voltage regulator. This is an effective method to solve voltage instability. With the voltage regulator installed, you can use electricity safely and stably anytime and anywhere. It should be noted that it is best to seek professional help when purchasing and installing voltage regulators.

(3) Install uninterruptible power supply. If conditions permit, UPS can be used to stabilize the voltage. UPS, also known as uninterruptible power supply, not only has the advantage of continuous use without power supply, but more importantly, it can stabilize voltage very effectively. Because its power supply is output through its own power supply. If UPS is used, the voltage will become very stable.

3. You can't switch the bulb on and off frequently. Sometimes children play with it, and the filament is hot and cold repeatedly, which can easily burn out the bulb.
