I am trying to figure out how to setup a power supply for my LED daytime running lights. They are currently H8 halogens. So the car supplies 12 v(which fluctuates up to 14.5v sometimes) and 35w on each DRLs.
I want to put 2 Cool white LUXEON LEDs in series in each light (http://www.luxeonstar.com/Cool-White...-pwc1-0120.htm)
. According to the datasheet, they are at 3.2v, 700ma each.
My understanding is that I have to put a voltage regulator (to avoid getting error message on my dashboard). Can anyone help me with the design of the power supply?
thanks in advance
