If you fix it like this, the LED light will last a lifetime, Repair the LED Light.
In most cases where LED lights fail, I think that there are many problems with the LED chip itself rather than the converter for LED.
It is said that LEDs have a long lifespan, and while it is true that they last a long time, you should not think of it as if you will use it for a lifetime.
Traditionally, it seems that the lifespan of LED lamps is over when about 5 years have elapsed.
The light in this video also broke after using it for just 5 years.
The LEDs used in this video are 5630 and 5730 models.
It is said that the standard indicates whether it is 5.6mm or 5.7mm. It is mainly used for lighting and the operating voltage is about 3.3v.
And when working with electricity like this, you have to turn off the electrical breaker and work.
And LEDs can be purchased at the electronic parts shopping mall. There are several stores by entering the electronic parts shopping mall in the search bar.
Each tester is slightly different, but about 3v is applied to the lead rod in short test mode or resistance mode.
I did the range in short inspection mode,
If the tester does not support it, you can test by connecting the battery to the correct voltage.
If you have a power supply, use it.
So hope it helps a lot.

In most cases, there were many problems with the LED chip itself, so please leave a comment. The opinions of many experts in the field
It is an opinion that there are many failures due to deterioration of the LED due to the problem of the LED converter.
It is still said that LED lamps have a shorter lifespan than expected due to the imperfect current of the converter.
