Harry, this reminds me to a fire wheel Nipkow disc that the late Mart Schouten made tens of years ago. But he had all LEDs in one long serie, each diode connected to a PCB commutator disc, glued on the Nipkow disc. Two contacts against that commutator disc powered only the LEDs close to and in the viewing area. You could do that too by giving each LED its own receiving coil and one transmitting coil that covers only the receiving coils of the LEDs that are close to and in the viewing field.
The advantage is that you can have more light out of the LEDs as they are powered only for a short time period and have enough time to cool down in the much longer off time. And still your transmitting power will be much lower.
