Load control system comprising linear lighting fixtures
A linear lighting fixture may comprise lighting control devices for controlling lighting loads in a load control system. Each linear lighting fixture may include a fixture controller configured to control lighting control devices. The fixture controller may receive messages from one or more devices in the load control system for controlling lighting control devices in the linear lighting fixture. The fixture controller may receive the message and communicate with the lighting control devices on a wired power/communication link Each linear lighting fixture may comprise one or more sensors. The sensors may be coupled to the fixture controller to send/receive messages on a wired power/communication link and/or a wireless communication link. The lighting control devices in the fixtures may be zoned separately or together. Each of the sensors in a linear lighting fixture may be zoned with one or more of the lighting control devices in the linear lighting fixture.

at least one second segment, wherein the at least one second segment comprises an occupancy sensor connected to the power/communication link, wherein the occupancy sensor is configured to detect at least one of an occupancy condition or a vacancy condition in a space;
a controller comprising at least one communication circuit configured to transmit one or more first messages via the power/communication link, the controller configured to control the at least one lighting load via the one or more first messages, and wherein the occupancy sensor is configured to transmit one or more second messages to the communication circuit via the power/communication link, the one or more second messages comprising an indication of the at least one of the occupancy condition or the vacancy condition in the space.
2 . The lighting device of claim 1 , wherein the at least one first segment comprises a plurality of separate lighting segments, and wherein the controller being configured to control the at least one lighting load via the one or more first messages comprises the controller being configured to control at least one corresponding lighting load in each of the plurality of separate lighting segments based on the one or more first messages.
3 . The lighting device of claim 2 , wherein each lighting segment of the plurality of separate lighting segments is configured for independent communication on the power/communication link using a corresponding identifier for receiving the one or more first messages for controlling the corresponding lighting load.
4 . The lighting device of claim 2 , wherein each lighting segment of the plurality of separate lighting segments is attachable to and detachable from at least one other lighting segment of the plurality of separate lighting segments.
5 . The lighting device of claim 2 , wherein each lighting segment of the plurality of separate lighting segments is associated with a respective zone.
6 . The lighting device of claim 5 , wherein each lighting segment of the plurality of separate lighting segments is configured for independent communication via the power/communication link using a unique zone identifier for the respective zone.
7 . The lighting device of claim 1 , wherein the occupancy sensor is mechanically connected to a first segment of the at least one first segment.
8 . The lighting device of claim 1 , wherein the power/communication link comprises a wired power/communication link, and wherein the occupancy sensor comprises an image recording circuit and an image processing circuit.
9 . The lighting device of claim 1 , wherein the communication circuit is configured to receive the one or more second messages via the power/communication link, and wherein the one or more first messages comprise an indication for the at least one lighting load to turn off based on the one or more second messages comprising the indication of vacancy in the space.
10 . The lighting device of claim 1 , wherein the one or more first messages comprise an indication for the at least one lighting load to turn on based on the one or more second messages comprising the indication of the occupancy condition in the space.
11 . A method comprising:
transmitting, via a power/communication link configured for providing power and communication within a lighting device, one or more first messages to control at least one lighting load installed in at least one first segment of the lighting device;
detecting, via an occupancy sensor installed in at least one second segment of the lighting device, at least one of an occupancy condition or a vacancy condition in a space, wherein the occupancy sensor is connected to the power/communication link; and
transmitting, via the occupancy sensor in response to the detection of the at least one occupancy condition or a vacancy condition in a space, one or more second messages via the power/communication link, the one or more second messages comprising an indication of the at least one of the occupancy condition or the vacancy condition in the space.
12 . The method of claim 11 , wherein the at least one first segment comprises a plurality of separate lighting segments, wherein the one or more first messages control at least one corresponding lighting load in each of the plurality of separate lighting segments.
13 . The method of claim 12 , wherein each lighting segment of the plurality of separate lighting segments is configured for independent communication on the power/communication link using a corresponding identifier included in the one or more first messages for controlling the corresponding lighting load.
14 . The method of claim 12 , wherein each lighting segment of the plurality of separate lighting segments is attachable to and detachable from at least one other lighting segment of the plurality of separate lighting segments.
