What kind of circuit is the street lantern (hanging on the LED tree) during the Spring Festival?
The circuit connection is not simply series or parallel, but like a grid.

If connected in series, a broken lamp will affect all the lamps in this circuit.

If it is connected in parallel, several lamps will be damaged, and then the overcurrent of other lamps will be greater, resulting in brightness difference.

If the circuit is driven, the first one uses switching power supply, and the second one can use resistance and capacitance to step down.
