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 their sensors. 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 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 may be processed along with the sensor data according to the internal logic to further enhance control of the lighting fixture.

First claim

What is claimed is:

1. A lighting fixture comprising:
a light source; and
circuitry adapted to:
drive the light source to provide light output;
provide a routing table comprising a next hop address for each of a plurality of destination addresses wherein each next hop address is positioned in the routing table based on a corresponding one of the plurality of destination addresses such that the plurality of destination addresses are not used to access the routing table;
dete…
