Abstract
A three phase rectifier rectifies received three phase a.c. power to generate a ripple d.e. voltage. A power distribution bus conveys distribution power comprising the ripple d.c. voltage or an a.c. voltage derived therefrom to a location of an LED based lamp that is distal from the three phase rectifier. Additional circuitry disposed with the LED based lamp drives the LED based lamp using the distribution power.
