System and method for controlling lighting
First Claim
1. A system for controlling lighting in a facility, comprising:
- a plurality of lighting fixtures configured for wireless communications;
a controller configured to create groups of lighting fixtures associated with different types of facility zones in a memory device of the controller, wherein the controller is configured to cause a first group of lighting fixtures to change from an operational algorithm not utilizing motion to an operational algorithm based on motion, and wherein the controller is configured to adjust a motion threshold for a motion-based operational algorithm for a second group of lighting fixtures;
wherein at least one lighting fixture of the first group of lighting fixtures wirelessly relays commands and data between the controller and at least one lighting fixture of the second group of lighting fixtures, wherein at least some of the second group of lighting fixtures are not within wireless transmission range of the controller, andwherein the controller is further configured to quantify a reduction in power obtained by controlling the first group and second groups of lighting fixtures according to their adjusted motion-based operational algorithms.

Abstract
A controller for controlling a plurality of lighting devices configured for wireless communications in a facility includes a data communications interface communicating with at least one of the devices. The controller further includes a control module configured to provide a control signal to the data communications interface for communicating to a transceiver associated with the device and for turning off the device according to an algorithm wherein the control signal is provided based on a time of day and/or a sensed condition relating to use of the facility. The transceiver reports device data to the control module to quantify a reduction in power obtained by controlling the devices according to the algorithm.
