One of the products I am seeking to design involves a small candelabra-sized low-power light bulb in a small glass. The goal is to embed an electromagnetic transmitter/primary coil inside a shallow wooden shelf (a regular 120V wall plug will run out of the shelf to provide power to the transmitter) and enable the light bulb in the glass to turn on when the glass is placed atop the wooden shelf (i.e. close enough within range of the transmitter's field to induce voltage in the receiving/secondary coil in the glass w/ the light bulb).
Obviously the TI bqTESLA setup is designed for low-power charging applications (and I have been successful in wirelessly powering LEDs using the eval models...) - but does anyone know what I would need to enable this application with traditional 120V bulbs? I already have loads of magnet wire (of various gauges), a full library of resistors/capacitors/etc., a function generator, oscilloscope, and several microcontrollers at my disposal (in addition to a Wurth charging receiver coil and the TI transmitter/receiver evals), but I am looking for the fastest-to-build solution if one does in fact exist.
Any insight would be much appreciated.
Thanks,
Justin
This picture below doesn't actually function as of yet (it's just a bulb in a glass with a handmade magnetic coil wrapped around and touching the bulb's current leads), but it would be great if the design could work out in a similar fashion...
