A method of controlling a lighting system comprising a plurality of illumination sources each controllable to emit illumination for illuminating the environment and a plurality of control apparatus for use in controlling the illumination emitted from one or more of the plurality of illumination sources, the method comprising: determining the relative position of a first control apparatus compared to a second control apparatus; assigning a function to the first control apparatus, the function defining how the first control apparatus is to control the illumination of one or more illumination sources, wherein the function of the first control apparatus is assigned based on the determined relative position; whereby a first user input can be received at the first control apparatus and the illumination of the one or more illumination sources can be controlled in response to the fist user input based on the assigned function of the first control apparatus.

A visible light sensor may be configured to sense environmental characteristics of a space using an image of the space. The visible light sensor may be controlled in one or more modes, including a daylight glare sensor mode, a daylighting sensor mode, a color sensor mode, and/or an occupancy/vacancy sensor mode. In the daylight glare sensor mode, the visible light sensor may be configured to decrease or eliminate glare within a space. In the daylighting sensor mode and the color sensor mode, the visible light sensor may be configured to provide a preferred amount of light and color temperature, respectively, within the space. In the occupancy/vacancy sensor mode, the visible light sensor may be configured to detect an occupancy/vacancy condition within the space and adjust one or more control devices according to the occupation or vacancy of the space. The visible light sensor may be configured to protect the privacy of users within the space via software, a removable module, and/or a special sensor.

Systems and methods to proactively adapt image sensor settings of an occupant monitoring system to accommodate ambient lighting changes are provided. The system may track current ambient light, track the driver, and predict upcoming changing lighting conditions. Sensors are used to predict when the ambient light will change and preemptively adjust to prevent dark or washout images. The sensor adjustment may be timed so that the adjustment is made just in time or concurrently with the change in ambient light conditions. The system may predict when the light on the occupant's face will change and proactively readjust the settings of the sensor to accommodate the changed lighting conditions.

A method of inactivating one or more pathogens in an environment. The method includes providing light from at least one lighting element of a lighting device installed in the environment, the at least one lighting element configured to provide light toward a target area in the environment, the provided light having at least a pathogen-inactivating first component in a first range of wavelengths of 400 nanometers to 420 nanometers. The pathogen-inactivating first component of light produces an irradiance of at least 0.01 mW/cm.sup.2 as measured at a surface in the target area that is unshielded from the lighting device and located at a distance of 1.5 meters from an external-most luminous surface of the lighting device. Providing the light causes the one or more pathogens to be inactivated.

A method of providing doses of light sufficient to deactivate bacteria throughout a volumetric space. The method includes: (1) receiving data associated with a desired illuminance level for the space, indicative of an estimated occupancy of the volumetric space over a pre-determined period of time, and indicative of dimensions of the space; (2) determining, based on the received data, an arrangement of one or more lighting fixtures in the volumetric space, the one or more lighting fixtures configured to at least partially emit disinfecting light having a wavelength of between 400 nm and 420 nm, and a total radiometric power to be applied via the one or more lighting fixtures to produce a desired power density at any exposed surface within the volumetric space during the period of time; and (3) installing the determined arrangement of one or more lighting fixtures in the volumetric space.

Apparatus and methods for deployment of fixtures. The apparatus may include a system for controlling deployed fixtures. The system may receive user commands different devices in different formats. The fixtures may be independently addressable. The fixtures may be magnetically supported by a fixture support. A brace may join two or more fixture supports without reducing space available to support fixtures. The brace may join a fixture support to a fixture support accessory. An accessory may include a variable-angle junction. The fixture may include articulating joints for controlling the direction of a beam. The fixture may include a lens having an electrically controllable beam spread angle. The fixture may be stowable in the fixture support. The fixture may be slidable along a cord to adjust a height of the fixture. The fixture may include an extendable ring. The system may coordinate motions of the fixtures to follow a target. The fixture may include an elongated board. The elongated board may include a non-polar power socket.
