Cooperative communications with multiple master/slaves in a LED lighting network
First Claim
1. A method of assigning a status to a lighting device of a plurality of lighting devices over a line, the method comprising:
- a) receiving, by a first lighting device of a plurality of lighting devices connected via a line used for providing intensity to the plurality of lighting devices, a signal over the line providing intensity, the signal comprising a duty cycle within a time interval, the duty cycle comprising a plurality of portions, each of the plurality of portions comprising a duration of the duty cycle;
b) detecting, by the first lighting device, an instruction identified by at least a first portion of the plurality of portions of the duty cycle, the instruction identifying a status of one of a master or a slave for the first lighting device;
c) assigning, by the first lighting device, the status of the first lighting device to one of the master or the slave in response to the detecting of the instruction; and
d) emitting, by the first lighting device, light having intensity identified by at least the first portion of the duty cycle.

Abstract
The present disclosure presents a relatively inexpensive yet intelligent solution for assigning a status to a lighting device over a connection used for transmissions of power and/or intensity for the lighting device. The system leverage and utilizes an existing connection that is available in many traditional lighting systems to provide intelligence between lighting devices, such as assigning a master or slave status to a lighting fixture or a device. For example, a typical lighting fixture may have existing connections such as for wiring and powering up the lighting fixture to modulate intensity of the light emitted. The present solution described herein provides systems and methods for utilizing the same wire to assign a status to the lighting fixture without interrupting the power supplied to the lighting fixture or the intensity emitted from the lighting device.

9. A system of a lighting device of a plurality of lighting devices assigning a status of a master or a slave over a line used by the plurality of lighting devices to provide intensity, the system comprising:
-
a first lighting device of a plurality of lighting devices connected via a line used for providing intensity to the plurality of lighting devices, the first lighting device receiving a signal over the line, the signal comprising a duty cycle within a time interval, the duty cycle comprising a plurality of portions, each of the plurality of portions comprising a duration of the duty cycle; a detector of the first lighting device detecting an instruction identified by at least a first portion of the plurality of portions of the duty cycle, the instruction identifying a status of one of a master or a slave for the first lighting device; an addressor of the first lighting device assigning the status of the first lighting device to one of the master or the slave in response to detecting of the instruction; and the first lighting device emitting light having intensity identified by at least the first portion of the duty cycle. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A lighting device assigning a status of a master or a slave based on a signal received over a line used to receive intensity, the lighting device comprising:
-
a receiver connected via a line used for providing intensity to the lighting device, the receiver receiving a signal over the line, the signal comprising a duty cycle within a time interval, the duty cycle comprising a plurality of portions, each of the plurality of portions comprising a duration of the duty cycle; a detector detecting an instruction identified by at least a first portion of the plurality of portions of the duty cycle, the instruction identifying a status of one of a master or a slave; an addressor, responsive to the detector, assigning the status of the first lighting device to one of the master or the slave in response to detecting of the instruction; and the lighting device emitting light having intensity identified by at least the first portion of the duty cycle. - View Dependent Claims (18, 19, 20)
