System and method for controlling lighting
First Claim
1. A controller for controlling lighting in a facility provided by a plurality of lighting fixtures configured for wireless communications, the controller comprising:
- a data communications interface communicating with at least one of the plurality of lighting fixtures; and
a control module configured to provide a control signal to the data communications interface for communicating to the at least one of the plurality of lighting fixtures and for at least one of turning on and turning off the plurality of lighting fixtures according to an algorithm that generates the control signal based on a time of day and an occupancy within the facility, the control module configured to determine the occupancy within the facility based on a sensed condition relating to motion within the facility and a level of carbon dioxide within the facility, wherein the control module is configured to compare the level of carbon dioxide within the facility with a carbon dioxide threshold associated with human occupation, and wherein the control module is further configured to quantify a reduction in power obtained by controlling the plurality of lighting fixtures according to the algorithm, and wherein the control module is configured to quantify the reduction in power by calculating the difference of (A) a first amount of power used by the lighting without control according to the algorithm with (B) a second amount of power used by the lighting as controlled by the algorithm.

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.
