The above picture is my design for driving the light illuminator. this cicuit should be able to adjust the potentiometer in order to manipulate the current driving to the light illuminator. My purpose is that this circuit are able to manipulate current from 0.2A to 1A to the light illuminator in order to control the brightness of light illuminator.
So my question is, is this circuit design can satisfied my requirement? how to consider the power dissipation for whole circuit? or do i need to change the value of resistor? Thanks.
