Series parallel Led light band problem
You see if there are any scissors signs on it, and if so, each section is the same. They are all connected in parallel. One transformer is ok.
It depends on the power supply voltage of your lamp belt. I don't know what you're using. If one meter is as long as 7 meters, it doesn't matter. As for the principle of luminescence, they are the same. But sharing the same transformer, that is, the power supply, must be the same as the two required supply voltage, otherwise it is easy to burn the lamp belt.
The same is true. It depends on how you answer it. If the 7 1 meters in parallel connection, each lamp to get brightness is 1, then 1 7 meters connection, each lamp brightness, is about the former 1/7. Share the same transformer, no problem, the main thing you need to consider is the brightness.
