Abstract: Embodiments are provided for systems and methods of managing a lighting system. According to certain aspects, the lighting system includes a low voltage controller (LVC) connected to multiple switches and to multiple drivers. Based on signals received from the switches, the LVC may determine a desired lighting setting as well as an adjustment setting of the lighting setting. The LVC may apply an appropriate signal to a driver to cause the driver to power a corresponding portion of luminaires. The LVC may include a memory configured to store adjustment settings so that the LVC may revert back to desired lighting and adjustment settings.

Abstract: A luminaire includes a housing defined by a pair of sidewalls, a bottom wall, and a first end wall. The first end wall has a first open-ended slot adapted to receive one or more wires. The luminaire also includes a first bracket removably coupled to the first wall to partially close the open-end of the first slot such that a hole remains. The hole is adapted to securely retain the one or more wires. The luminaire further includes a closure coupled to the housing and configured to close the housing. The closure is configured to include one or more light-emitting components.

Abstract: Embodiments are provided for a lighting system and a method of installing a lighting system. According to certain aspects, a driver box is configured with a plurality of drivers secured therein. A series of wired connections can couple the plurality of drivers to a plurality of luminaires and can conduct electric power from the plurality of drivers to power the plurality of luminaires. According to aspects, the driver box and its plurality of drivers are located remote from the plurality of luminaires to enable efficient maintenance of the lighting system.

Abstract: A lighting device configured to deactivate pathogens in an environment. The lighting device includes at least one first light-emitting element configured to emit light having a wavelength of between 400 nm and 420 nm, wherein the light emitted by the at least one first light-emitting element is configured to deactivate the pathogens in the environment. The lighting device also includes at least one second light-emitting element configured to emit light having a wavelength of greater than 420 nm. A first combined light output of the light emitted by the at least one first and the at least one second light-emitting elements includes visible light that is perceived as white light. The white light has properties that make it visually appealing and unobjectionable.

Abstract: 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.

Abstract: A lighting device configured to deactivate dangerous pathogens (e.g., MRSA bacteria) in an environment. The lighting device includes at least one lighting element configured to provide light. At least a first component of the light comprising light having a wavelength of between 400 nm and 420 nm, and at least a second component of the light comprising light having a wavelength of greater than 420 nm. The first component of light has a minimum integrated irradiance of 0.05 mWcm2 measured from any unshielded point in the environment that is 1.5 m from any point on any external-most luminous surface of the lighting device.

Abstract: A light fixture and a housing thereof for managing thermal energy includes multiple cavities separated by a partition wall and each configured to house components of the light fixture, in particular an LED array and LED drivers to power the LED array. The housing further includes a heat transfer flow path radially defined between the first cavity and the partition wall, and a fin in fluid communication with the cavity housing the LED drivers. The heat transfer flow path is positioned for dissipation of heat from the LED array and the fin is positioned for dissipation of heat from the LED drivers.

Abstract: A lighting fixture including a housing having sidewalls and lengthwise ends, an elongate lens fitted to the housing with lengthwise end edge portions, a pair of unitary endplates each attachable to either lengthwise end of the housing, each endplate having lens support structure supporting one lengthwise end edge portion of the lens, and each endplate having perimeter surfaces matingly attached to an endcap having a peripheral edge of substantially the same size and contour as the outer surface of the endplate where the endcap and endplate join. Each unitary endplate includes perimeter surfaces matingly attached to a linear bridge, an angular bridge or an endcap having a peripheral edge of substantially the same size and contour as the outer surface of the endplate where the bridge or endcap and endplate join. The endplate support prevents the elongate lens from being pressed inwardly into an interior portion of the lighting fixture.
