12V isn't enough to power qty 20 of any LED that are connected in series, most require a bare minimum of 1.7V each which means 20 of them in series would require 34V.I have a 24v to 12v converter which feeds 20 LEDs in series. The LEDs are rated at 12v.[/I]
He wanted to say in parallel.12V isn't enough to power qty 20 of any LED that are connected in series, most require a bare minimum of 1.7V each which means 20 of them in series would require 34V.
Obviously we're missing some key inforation here.
Apparently so, as it is the only one remaining lit when you turn the power off.Thanks
Ok so my new LED has a lower Forward Voltage than the rest.
Yes; it is the path of least resistance.(1) And is this the reason it is staying slightly on ?
Yes.(2) Is the "Forward Voltage" the same thing as the "Voltage drop" across an LED.
There is a charge stored in your supply output capacitor(s).(3) So even when the supply is switched off to it, there is still a voltage across it ?
