SMART POWER DEVICE
First Claim
1. A system comprising:
- a power converter configured to power a plurality of light fixtures with direct current power signals transmitted over wiring from the power converter to the light fixtures; and
a power communicator configured to communicate with a plurality of load communicators, each of the load communicators paired with a corresponding one of the light fixtures, whereinthe power communicator is further configured to determine a respective target power level for each of the light fixtures based on the communication with the load communicators and to cause the power converter to the power each of the light fixtures at the respective target power level.

Abstract
A power device may include channels coupled to conductors in lines, where each one of the channels is coupled to a different one of the lines than the other channels and where the channels deliver direct current power signals over the conductors to the load devices. Each one of the load devices may be powered by a different one of the direct current power signals. The power device may include a power communicator that communicates with the load devices over the conductors that propagate the direct current power signals. The power communicator may determine a target power level for the load devices based on the communication over the conductors. The load device may adjust an amount of power in the direct current power signals in order to match the target power level.
