A method of deploying the lighting network may include steps of providing a plurality of light units, placing each of the light units within a communication range, causing each of the light units to enter PAIRING MODE, causing each of the light units to add, into its network list, other unique identifiers of other light units; and causing each of the light units to enter PAIRED MODE. Light units function identically with respect to received reserved commands. Any light unit can broadcast commands, causing all light units in the network, or a subset thereof, to execute the command. Such commands may cause the desired lighting configuration.

A method of merging a first lighting system with a second lighting system is disclosed. The first lighting system comprises a plurality of first lighting devices located in a space and a first lighting control system for controlling the plurality of first lighting devices, and the second lighting system comprises a plurality of second lighting devices located in the space and a second lighting control system for controlling the plurality of second lighting devices. The method comprises: obtaining one or more signals, which one or more signals are indicative of a location of a second lighting device of the plurality of second lighting devices relative to a first lighting device of the plurality of first lighting devices. determining if the second lighting device is located within a predetermined proximity range of the first lighting device based on the one or more signals, obtaining, from the first lighting control system, information indicative of an association between the first lighting device and an area in the space, associating, if the second lighting device is located within the predetermined proximity range, the second lighting device with the area associated with the first lighting device, storing the association in a memory of the first lighting control system, and connecting the second lighting device to the first lighting control system.

A method for controlling light-emitting devices includes: receiving broadcast signals broadcasted by light-emitting devices; obtaining a lighting video collected during lighting state switching of a light-emitting device; performing lighting state identification based on the lighting video, and determining a second lighting switching instruction message for switching the lighting state of each light-emitting device in the lighting video; matching the first lighting switching instruction message indicated by the broadcast signal with the second lighting switching instruction message corresponding to each light-emitting device in the lighting video to determine a broadcast signal corresponding to each light-emitting device in the lighting video; determining a network address of each light-emitting device in the lighting video based on the determined broadcast signal corresponding to each light-emitting device in the lighting video; and according to the network address of each light-emitting device in the lighting video, controlling a corresponding light-emitting device.

An LED light fixture includes one or more optical transceivers that have a light support having a plurality of light emitting diodes and one or more photodetectors attached thereto, and a processor in communication with the light emitting diodes and the one or more photodetectors. The processor is constructed and arranged to generate a communication or data transfer signal.

A load control system may include a load control device for providing power to an electrical load and a control device that may send instructions to the load control device for providing the power to the electrical load. The control device may communicate with the load control device using a link address assigned to the load control device. The load control device may provide power to the electrical load in a manner that causes the electrical load to indicate the link address assigned to the load control device. The link address may be identified by a user or a user device. The identified link address may be associated with a load control device identifier that may identify a physical location of a load control device that is assigned the link address. A user may control a load control device at a physical location by sending instructions via the link address.

An advanced lighting control system including systems for commissioning a network of lighting fixtures preferably includes a plurality of lighting fixtures, each having a sensor and control module. The sensor and control module includes occupancy and light sensing elements, and a first transceiver. The lighting fixtures can send wireless signals to a second transceiver located in a room controller and/or a network coordinator. The room controller being configured to interpret the occupancy and light sensing information and make decisions thereon, while the network coordinator can rank the lighting fixtures according to a determined signal strength. The network coordinator can command each of the lighting fixtures to illuminate, and based on an observation of the lighting fixture, a determination is made about whether the lighting fixture is located in a particular room. The network coordinator can also include a third transceiver for receiving wireless commands from a remote device.

Enhancements to ornamental or holiday lighting are disclosed including remote control ornamental illumination with color pallet control whereby a user can vary the color/intensity/appearance of an individual bulb or entire light string by selecting the electronic address of the bulb and selecting its attribute. Further disclosures include: motion responsive lights which respond to sensed movement, gesture controlled lights, adjustable white color/white led sets, connectable multi-function lights, controller to sequence lights to music or other input source, rotating projection led light/tree top/table top unit, and remote controlled sequencing icicle lights and ornament lighting system.

An example of an apparatus is provided. The apparatus includes a communications interface to receive data from a plurality of lighting devices. The data from a lighting device includes a distance and a bearing for neighboring lighting devices of the lighting device. The neighboring lighting devices are selected from the plurality of lighting devices. In addition, the apparatus includes a memory storage unit to store the data received via the communications interface, wherein the data is to be stored in a database.
