Abstract
A power management system for the control and operation of distributed power has a controller operatively connected to a plurality of monitors, switches, control devices, and a visible light emitting array. The monitors, switches, and control devices provide the means for the controller to modulate the power to the visible light emitting array using a current modulator. The current modulator produces a variable power duty cycle that is received by the visible light emitting array. The visible light emitters of that array have a selected perceivable brightness. That brightness is held constant but power is conserved due to the controller modulating the power.
