Abstract

Control of lighting fixtures in a lighting network may be distributed among the lighting fixtures. The lighting fixtures may be broken into groups that are associated with different lighting zones. At least some of the lighting fixtures will have or be associated with one or more sensors. Within the overall lighting network or the various lighting zones, the lighting fixtures may share sensor data from the sensors. Each lighting fixture processes sensor data provided by its own sensor, a remote standalone sensor, or lighting fixture, and processes the sensor data according to the lighting fixture's internal logic to control operation of the lighting fixture. The lighting fixtures may also receive control input from other lighting fixtures, control nodes, light switches, and commissioning tools. The control input is processed along with the sensor data according to the internal logic to enhance control of the lighting fixture.

First claim

What is claimed is:

1. A lighting fixture comprising:
a light sensor;
a light source; and
circuitry adapted to:
determine that a given lighting fixture of a plurality of lighting fixtures is entering a lightcast mode, in which the given lighting fixture emits a first lightcast signal via a light source of the given lighting fixture to group lighting fixtures;
via the light sensor, monitor for the first lightcast signal provided by the given lighting fixture; and
effect ge…
