COMMUNICATION SYSTEM FOR ADAPTIVE LIGHTING CONTROL
First Claim
1. A lighting system to control illumination of a plurality of areas, the lighting system comprising:
- a lighting fixture matrix including a plurality of lighting fixtures respectively located at the plurality of areas, each of the lighting fixtures including a sensor and a controller coupled with the sensor, a first sensor being configured to detect the presence of a user in a first of the plurality of areas; and
a communication circuit configured to provide communication between each of the plurality of lighting fixtures;
wherein upon detection of presence of a user in the first area, the respective controller is configured to illuminate a first of the lighting fixtures and send a signal to simultaneously trigger illumination of two or more of a remaining number of the plurality of areas.

Abstract
Provided is a lighting system to control illumination of a plurality of areas. The lighting system includes a lighting fixture matrix having a plurality of lighting fixtures respectively located at the plurality of areas. Each of the lighting fixtures includes a sensor and a controller coupled with the sensor, a first sensor being configured to detect the presence of a user in a first of the plurality of areas. The lighting system also includes a communication circuit configured to provide for communication between each of the plurality of lighting fixtures. Upon detection of presence of a user in the first area, the respective controller is configured to illuminate a first of the lighting fixtures and send a signal to simultaneously trigger illumination of two or more of a remaining number of the plurality of areas.

11. A method for controlling illumination of a plurality of lighting fixtures within a lighting fixture matrix via a signal having a specified number of pulses, the signal being transmitted from a central lighting fixture of the plurality, the method comprising:
-
sensing presence of a rising edge of the first of the pulses when the signal is received at a neighboring one of the plurality of lighting fixtures; and determining whether a width of the first of the pulses is wide or narrow based upon a time quanta; wherein the sensing and determining applied to a remaining number of the pulses within the multi-pulse signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
