How to wire and power LEDS with a constant current driver? Answered
I want to light up 6 leds, one each of red, orange, yellow, green, blue, purple.
The specs for red, orange, and yellow are: 20 mA, 2 V. Green, blue purple are 20 mA, 3 V.
I ordered these constant current drivers http://lighthouseleds.com/20ma-led-current-limiter-driver.html
20mA (+/- 3) Constant Current
Output Voltage Varied (constant current)
Input Voltage 2-45V Across Limiter
Now, how do I wire the leds and what type of battery do I use? On the current driver website it shows 3 leds in series with the driver and battery. I was thinking of using a 9 volt battery. But placing my 6 leds in series would add up to a total of 15 volts, and wouldn't work, correct?
So, do I need to wire 2 or 3 leds in series, then put those groups in parallel? Do I need another current driver?
Thanks in advance.
