Abstract: Disclosed herein is a lighting system configured to obtain an indicator data of a RF spectrum signal generated at a number of times in an area. At each respective one of the number of times, apply one of a plurality of heurist algorithm coefficients to each indicator data from a receiver for the respective time, based on results of the applications of the coefficients to indicator data, generate an indicator data metric value for each of the indicator data for the respective time, and process the indicator data metric values to compute an output value. The lighting system is further configured to compare the output value at each of the plurality of times with a threshold to detect one of an occupancy condition or a non-occupancy condition in the area and control the light source in response to the detected one of the occupancy condition or the non-occupancy condition in the area at each of the number of times.

Abstract: A luminaire includes a housing, a luminous zone coupled with the housing, and one or more transition zones coupled with the housing and disposed adjacent to the luminous zone. The luminous zone provides a first light to an illuminated area, and the one or more transition zones provide a second light to the illuminated area. The first light is harsher than the second light. A method of illuminating an area includes providing a first light to the area from a luminous zone of a luminaire and providing a second light to the area from one or more transition zones disposed adjacent to the luminous zone within the luminaire. The first light is a harsher light than the second light.

Abstract: 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.

Abstract: Certain aspects involve lighting systems relating to control of light fixture dimming. For instance, a lighting system may include a first light source that outputs a first light color and a second light source that outputs a second light color. The lighting system also includes a switching device that couples and decouples the second light source in parallel with the first light source. The switching device includes a first setting that couples the second light source in parallel with the first light source and enables a variable color dimming operation. The switching device also includes a second setting that decouples the second light source from the first light source and enables a static color dimming operation.

Abstract: Disclosed are examples of spectrometer-equipped devices that provide general illumination supplied by artificial or natural light, and that also detect substances in the environment around the device. In some examples, light may be emitted by a spectrometer light source. The spectrometer detects the light from any of a natural light source, artificial general illumination light or light from the spectrometer light source passed, reflected or shifted and regenerated by substances in the air or on a surface in the vicinity of the device. In response, the spectrometer generates signals representative of the spectral power distribution (e.g. intensities of given wavelengths in the optical spectrum) of the detected light. A controller analyzes the spectrometer generated signals and initiates action based on or outputs a report indicating the environmental condition detected by the spectrometer-equipped device.

Abstract: A junction box housing system includes a housing, a first hanger connected to a first side of a sidewall of the housing, and a second hanger connected to a second side of the sidewall distal from the first side. In various examples, the housing is movable along the first hanger and the second hanger in a horizontal direction.

Abstract: A luminaire may include a plurality of different light engines. Light engines having different light distributions can be included in a single luminaire and a subset of the light engines selectively driven to dynamically change the light distribution of the luminaire. In this way, a single luminaire is capable of illuminating an area with a variety of different light distributions.

Abstract: Described are embodiments of a light engine installation kit and methods of installation that allow a single technician to install large, heavy, or awkwardly shaped light engines into new or existing fixture housings. The installation kits include mounting brackets that install into the fixture housing. The mounting brackets can then support the light engine by a retention tab at one end, and a tether at the other. In this intermediate position, an installer can complete the wiring before raising the light engine into its final position. Also described are lenses, wireway covers, reflectors, and end caps that provide improved sealing of the lens compartment of a light engine. The fitting of the parts provides better sealing to prevent dirt, debris, or insects from migrating into the lens compartment of the light engine and causing reduced light output or unsightly dark spots in the lens.

Each of the reflector, the channel, and the PCB includes a feature(s) that permit their attachment to each other without the need for separate fasteners and tools. Embodiments of the LED luminaire may also include an optic and a pair of end caps, also designed for assembly into the LED luminaire without the use of or need for separate fasteners and tools.

Abstract: The examples relate to various implementations to enable simultaneous controllable lighting distribution and a wide angle image light output from areas of a luminaire. An example of such a luminaire includes image light emitters and an array of general illumination light emitters for general illumination. A grid structure that has a supporting grid of rows and columns with intersection points and transparent sections or gaps is used to maintain a spaced arrangement of the general illumination light emitters and the image light emitters. Each of the transparent sections is bounded by individual structural members of the grid meeting at individual intersection points. In a specific example, image light emitters are located at intersection points of the grid structure. The general illumination light emitters are optically coupled for emitting general illumination light through the transparent sections of the grid.

Abstract: Optics for asymmetrically redirecting light from one or more light engines include a dome optic, and first and second reflecting surfaces. The dome optic refracts light emitted by the light engines. The first reflecting surface redirects at least a portion of the light that is initially emitted toward a backward horizontal direction, toward the forward horizontal direction. The first reflecting surface extends substantially vertically and along a transverse horizontal direction, proximate to and behind the dome optic, and has a height greater than or equal to a height of the dome optic. The second reflecting surface reflects downwardly at least a portion of the refracted light that is initially emitted in the forward horizontal direction. The second reflecting surface is proximate to the dome optic and forward of the dome optic, and forms an angle of 45 degrees or more with respect to vertical.
