Commutation
Posted: Tue Dec 04, 2012 6:01 pm
Just thinking about what Steve was asking about in my lens disk topic the idea of commutation for lights leds and how it might be done today .
On the Slip rings idea i think Steve is not keen on ? i didn't know what they were , these pictures are an idea like that i think?
On a electronic idea i can see 2 problems the power and nbtv communication to the electronics that would have to rotate with the leds lights what ever .
The power part might be a way.... 2 motors one used as a generator but the nipkow would have to be mounted with the generator part as well see very messy picture ...better to explain with a picture .
The communication between the nbtv signal to the leds electronics a light communication systems perhaps using a mask and a ldr and a little trany amp to each 32 led ?
Well just an idea perhaps a workable system least theres no mechanical brushes apart from the motor used as a generator .
