Rated voltage of LED lamp string

How does the LED light string flash?
- Because of the special volt ampere characteristics, LED can not use constant voltage driving mode, but is driven by cross flow. The direct drawback of cross flow drive, however, is heat. So people invented the drive mode of pulse drive. For example, 0.5 seconds per second, so that the amount of heat in the LED is reduced by half. Then turn the frequency up to 100 times per second, lighting for 0.005 seconds each time. At this point, the power of the LED is not the same, and people do not feel blinking. What's more, in this driving mode, an approximate cross flow drive (that is, the current is not necessarily precise) can be simplified, which simplifies the drive circuit (the precise cross flow source is very complex)s
