He had been designing low-voltage VFDs for Get price

idea to make an LED with variable light output frequency

Nov 13, 2011able to output variable frequency light. If the LED wafer is sandwiched between two metal screens, ie. to put it inside a capacitor, then the capacitor could modify the electric field of the bandgap, to adjust the output light frequency. Anyone ever try this? cheers, Jamie. Get price
