How to detect the power supply  LED lighting?

 

If there is a voltage of more than 100 volts (such as 60 LEDs, which have about 190V DC voltage at both ends), then the driving power supply is good. Only if one LED is broken, the whole lamp will not turn on. On the contrary, if no voltage is measured, the driving power will be good. If the power supply is bad, I can communicate with you if there is any problem.
