I apologize in advance is this is a stupid quesiton. I am a beginner when it comes to electronics and this idea may be completely off base.
I am trying to setup LED lights in a garage. These will be 12v DC powered light strips, and I would like to have them come on via a normal wall switch OR when the garage door is opened. I will be hacking the garage opener to use 120v that normally goes to the light on the opener. I also have a wall socket that I can just plug into for the wall switch.
My question is, if I hook up two 12v power supplies and attach them in paralell, would they fry the LEDs if both were turned on? Is there some kind of switch before the LEDs that would only allow one input at a time?
The ideal solution would be to actually have a single power supply that would accept 2 120v inputs w/ a single 12v output. I have searched and I am not sure which direction would be best / safest / cheapest / even possible. Any guidance would be appreciated. Thanks!
