Hi guys,
I am trying to build a mood light but I'm having big trouble in powering the led's. I am using 3x 3W RGB star Led's. 'Ive been stuck on this for 3 days and so far i've come up with this:
Use constant current power supply with 10-12V rating(possibly up to 16V with no load).
Use some sort of voltage regulator to drop it down to 10v (this is where i'm stuck). After that I'm planning to connect each colour of the led's in series for a total of 9.6-12.4V (3.2-3.8 each) and 7.5-9V (2.5-3) for red colour led modules. This voltage difference can be dropped with resistors. I'm not going to worry about the rest for now, I need to get the led's lit first
Can anyone suggest a good compromise between efficiency and complexity? Voltage regulator seems to be what I need but I don't know enough to build one so if you can give the list of parts I would need that would be fantastic! Any other alternatives welcome too of course.
Any suggestions where to get these parts? Now I am using radionics online. (i'm in europe btw).
Any help really appreciated!
