Lighting units, systems, and methods are described herein for determining whether occupancy detections are legitimate or not. Methods and systems are further described herein for powering down a network of power over ethernet (PoE) components.

Techniques are described for a lighting system in which light sources are controllable using signals sent over a wireless mesh network. During a commissioning process, a user interface (UI) may present a representation of nodes (e.g., light sources, sensors, controllers, etc.) that are broadcasting a wireless advertising signal. In response to a selection of a particular node, a wireless message may be sent to instruct the selected node to provide a visual indication of its presence, such as a flashing light. The visual indication may enable a user to discern the physical location of the node, such that each node may be added to the mesh network and, in some instances, to a group of nodes. The UI may also enable the definition of scenes, where each scene describes the brightness level or other operating characteristics of particular light source(s) and/or group(s) of light sources when the scene is active.

Methods, systems, and devices are described for commissioning light fixtures. One method may include receiving, at a mobile device, an encoded light signal from a light fixture in a plurality of light fixtures. The encoded light signal may be decoded to obtain an identifier associated with the light fixture, and a correspondence between the identifier and a plurality of locations of the plurality of light fixtures may be determined.

An illumination system includes a luminaire, a controller, and a switch that turns ON and OFF power supply to the luminaire. The controller includes: a light intensity controller that performs light intensity control of controlling the brightness of the luminaire; and a power supply controller that instructs the switch to turn OFF the power supply to the luminaire on which the light intensity control is performed at a light intensity rate that is equal to or greater than 0 and at most a predetermined value.

The disclosure provides examples of systems and methods for determining locations of a number of radio frequency-enabled devices such as mobile devices and radio frequency-equipped beacons/luminaires within an indoor location. The radio frequency-enabled devices may be part of an indoor positioning system and/or content delivery system. The examples describe obtaining an angle of arrival (AoA) of the signals received by the respective radio frequency-enabled devices. The AOA data is used to identify the relative positions of the radio frequency-enabled devices as the mobile device moves about the indoor location. Upon comparing AOA measurements of the collected data related to a map of the location, the system may generate a data structure that may be presented graphically as a map of positions of the devices at the location. The described examples may enable a rapid commissioning process with respect to the radio frequency-enabled devices in a network.

A setting device includes: a communication circuit which communicates with a target lighting fixture in which a communication configuration is to be set up among lighting fixtures; a display which displays layout information of the lighting fixtures; a detector which detects a direction of movement of the setting device inside of a building, and an amount of the movement of the setting device; and a controller which causes the display to display, on the layout information, a position of the setting device derived based on the direction and the amount of the movement of the setting device. The controller determines whether the position of the setting device is within a predefined area, based on a location of the target lighting fixture, and sets up the communication configuration in the target lighting fixture via the communication circuit when the position of the setting device is within the predefined area.

The lighting system enables the communication and thereby the creation and/or expansion of a network between a sensor and any number of light sources. The network preferably enables the monitoring and controlling of the light sources by the sensor via a wireless communication. The light source can be an LED lamp, an LED lamp tube, an LED retrofit lamp, preferably a retrofit T8 tube, a fluorescent lamp and/or a halogen lamp. The light source can be a ceiling lamp, a wall lamp, a bottom illumination, direct or indirect lighting, a signal lamp and/or a decorative lighting. The sensor is responsible for creating and/or expanding a wireless network between the sensor and the at least one light source.

An electronic building automation system, comprising multiple electronic building automation devices and a commissioning device. The multiple electronic building automation devices comprising a beacon receiver arranged to receive localizing beacon signals transmitted from multiple beacons installed in the vicinity of the multiple building automation devices. The commissioning device being configured to localize a building automation device using the localization information in a beacon message received from the building automation device to obtain an estimated location of the building automation device to commission the building automation device in the building automation system.

Described herein is method for setting up a network of luminaires and their subsequent operation. A plurality of luminaires are located on a street (24, 29), and each luminaire comprises a control module (23, 28). The method for setting up the network comprises, for each control module, scanning the environment and providing environmental information to a central server, which, allocates the control modules and their associated luminaires into groups (A, B). A group controller (23, 28, 31, 32) is allocated for each group which has long-distance communication with the server and short-distance communication with control modules within its group. Each group controller and control modules within the group form a network which can operate autonomously or under the control of the server. Some of the control modules may include sensors (S1, S2) which provide signals indicative of changes in the environment allowing the network to adapt its operation in accordance with those changes.

A method and apparatus for assigning addresses to components sharing a common bus. In one embodiment, an iterative elimination process is used to assign the addresses to each component. In another embodiment, each component includes a distance sensor that detects a distance to a front face of a calibration plank. Addresses are assigned to the components based upon the distance readings of the sensors.
