Power RGB LED help!
I have just bought a self contained RGB controller with PWM'd outputs:
What I want is to use this for the lighting in a vehicle (12 - 14.6V). The LEDs I have looked at and bought one for testing are:
Now - the vehicle has a removable rear cabin leaving only the front cabin LEDs connected at times. I will need say 6 - 7 LEDs for the rear cabin and 2 - 4 for the front cabin depending on eventual light output.
Should I drive these LEDs with constant current drivers for each colour? Will they work with the PWM output of the controller?
I understand switched regulator type circuits won't work with the PWM output?
I guess I would need several contant current regulators to power the array but am struggling on how many and how best to connect them?!?
Thanks in advance!
