Abstract

A lighting network where control of the lighting fixtures in the network may be distributed among the lighting fixtures. The lighting fixtures may be broken into groups that are associated with different lighting zones. Certain lighting fixtures will have or be associated with one or more sensors, such as occupancy sensors, ambient light sensors, and the like. Within the lighting network or the various lighting zones, lighting fixtures may share sensor data. Each lighting fixture may process sensor data provided by its own sensor, a remote standalone sensor, or lighting fixture, and process the sensor data according to the lighting fixture's own internal logic to control operation. The lighting fixtures may also receive control input from other lighting fixtures, control nodes, light switches, and commissioning tools. The control input may be processed along with the sensor data according to the internal logic to further enhance control of the lighting fixture.
