Howdy,
I'm making a simple lamp using 3 white LEDs. I've set up a simple circuit that works well enough and has the schematic
See in "basicLamp.png"
However, I would like for it to operate off my AC/DC adapter regularily, and only use battery power when the power from the wall adapter is removed. Would a simple circuit using some diodes work?
See "possibleLamp.png"
Any other suggestions would be much appreciated. I was thinking of using a P-Channel JFET or a depletion MOSFET instead. Would that route be more recommended?
