Abstract

A lighting device, comprising: a circuit board; a receiver coil trace located on the circuit board and configured to receive transmitted power from a transmitting coil trace; a light-emitter located on the circuit board, configured to receive power from the receiver coil trace; and receiver electronics located on the circuit board, configured to receive power from the receiver coil trace and control operation of the light emitter.

Claims

1. A lighting device, comprising:

a circuit board;

a receiver coil trace located on the circuit board and configured to receive transmitted power from a transmitting coil trace;

a light-emitter located on the circuit board, configured to receive power from the receiver coil trace; and

receiver electronics located on the circuit board, configured to receive power from the receiver coil trace and control operation of the light emitter.

2. The device of claim 1, wherein

the light emitter is located on a first surface of the circuit board,

the receiver coil trace is located on a second surface of the circuit board opposite the first surface.

3. The device of claim 2, wherein the receiver electronics are located on the first half of the first surface of the circuit.

4. The device of claim 2, wherein the receiver electronics are located on the second half of the first surface of the circuit.

5. The device of claim 1, wherein

the light emitter is located on a first half of a first surface of the circuit board,
