Can I wirelessly power mini LEDs?
It is possible to power LED wirelessly, and the process is quite simple.


For the receiver, you just need to build a coil and connect it to a LED.
For the transmitter, you'll need another coil. This one is powered by an AC voltage.


In  order to work, the LED's coil must be prependicular with the magnetic field created by the transmitter.

You can think of this as transformer where you replace the core with air. The transmitter is the primary of the transformmer and the receiver is the secundary.

You can see the explanation in this video.
