Is there any connection between the series connection and parallel connection of the LED light source for lighting LED?
Power matching, or 12V power supply for example lamp is only 3 of the 0.5W string is 1,5W when 3W is 2 6W to 4 parallel serial parallel. Street lamps require greater power. 7 a power 24V lamp 1W conditions for 7W requires a certain brightness requirements will be 10 sets of parallel 70W. This is just a basic match principle, which is much more complicated in actual use. Your question is also one of the bottlenecks encountered in LED communications. I think you might have figured it out.
Depending on use, and used only in multiple circumstances will affect the consistency of the beads and others
LED lamp series and parallel is mainly to supply voltage, or power requirements, and appropriate; examples: 1, voltage, assuming lamp working voltage is 3,4v and 12V battery, that will be 3 only because the remaining 1,8V 3,4*3=10.2V series with a current limiting resistor in series lamp beads only consumption off. If matched with the 24V battery, it will be 7 series 24/3,4=7 more than 0,2V, visible efficiency is much higher, and 48V power matching, that is, 48/3,4=14 only series, and 96V power matching, that is, 96/3,4=28 only series.
