Hi everyone,
i need your advice on a project i’m working on.
i have an LED street light (3.8V , 700mA) which i need to make a control system for it.
1- is it better to drive the LED by a switched mode regulator with constant current or constant voltage regulator?
2- i’m using PWM to dim the LED, so my choice is a constant current regulator, since i’m turning the driver on and off at high frequency from a PWM signal coming from the Arduino. am i correct?
i looked up through these information, but i just need some more explanation.
regards...
