Abstract: A luminaire includes a housing, a downlight that includes one or more first light sources configured to emit a first light downwardly from the housing, a waveguide, and one or more second light sources. The waveguide is formed of a portion of an optical material and characterized by opposing planar faces joined by one or more edge faces about a periphery of the optical material. The waveguide forms at least a portion of an uppermost optical surface of the luminaire. The one or more second light sources are coupled with the housing and configured to emit a second light into the optical material through at least one of the one or more edge faces. The waveguide is configured to emit at least a portion of the second light upwardly from an upper one of the planar faces.

Abstract: A system includes a control device and a plurality of lighting fixtures configured to receive power through the control device. Each lighting fixture includes a receiver and a memory, and is configured to: scan for a first message transmitted by the control device, the first message containing a unique identifier of the control device; receive the first message and store the unique identifier of the control device in the memory; sense a power interrupt to the lighting fixture initiated by the control device within a specified period of time after receipt of the first message from the control device; and transmit a second message including the unique identifier of the control device, the second message indicating that the lighting fixture is in a provisioning mode.

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: A light fixture mounting assembly includes a surface mount, a lighting unit mount configured to engage the surface mount, and an arm connecting the surface mount to the lighting unit mount. The lighting unit mount is movable in use between a first configuration in which the lighting unit mount is disengaged from the surface mount and supported by the arm and a second configuration in which the lighting unit mount is engaged to the surface mount. Moving the lighting unit mount from the first configuration to the second configuration includes moving the lighting unit mount relative to the surface mount in a first direction to cause the surface mount and the lighting unit mount to draw closer together in a second direction that is nonparallel to the first direction.

Abstract: A driver box for a light fixture includes a first compartment and a second compartment. The first compartment defines a first end of the driver box, and the second compartment defines a second end of the driver box opposite from the first end. The first compartment is pivotable relative to the second compartment. A method of installing a light fixture assembly includes pivoting the first compartment of the driver box relative to the second compartment of the driver box to a first orientation such that the driver box is insertable into an installation opening. The method includes inserting the driver box into the installation opening.

Abstract: Silicone-containing light fixture optics. A method for manufacturing an optical component may include mixing two precursors of silicone, opening a first gate of an optic forming device, moving the silicone mixture from the extrusion machine into the optic forming device, cooling the silicone mixture as it enters the optic forming device, filling a mold within the optic forming device with the silicone mixture, closing the first gate, and heating the silicone mixture in the mold to at least partially cure the silicone. Alternatively, a method for manufacturing an optical component may include depositing a layer of heat cured silicone optical material to an optical structure, arranging one or more at least partially cured silicone optics on the layer of heat cured silicone optical material, and heating the heat cured silicone optical material to permanently adhere the one or more at least partially cured silicone optics to the optical structure.

Abstract: A lighting fixture for powering multiple LED groups to generate a selectable color temperature. The lighting fixture provides varying amounts of power to each group of LEDs to achieve a selected color temperature. Current from a driver may be divided between the LED groups based on a selected operational state, which is selected using a switch or other configurable input. The operational states may turn the LED groups on or off or may control an amount of current received by the LED groups. In some configurations, all of the LED groups are always at least partially powered.

Abstract: An emergency LED lighting system maintains power to an LED lighting source based on measured voltages and currents provided to the LED lighting source; rolls back or decreases power provided to an LED lighting source over time in order to increase the amount of time the battery can power the LED lighting source; executes a soft start procedure, such that the power provided to the LED lighting source is gradually ramped up during activation of the LED lighting sources; identifies a type of battery coupled to the emergency LED lighting system; cycles the emergency LED lighting system between charging mode and standby mode to reduce power consumption over a window of time; detects AC power or an absence of AC power; and/or uses a status LED to communicate information about the emergency LED lighting system with a remote device.

Abstract: A luminaire includes a housing assembly, a spacer, and a globe optic. A collar may be included on the spacer such that the luminaire can accommodate different sizes of globe optics without requiring complete replacement of the luminaire. The spacer may include airflow apertures that promote air circulation within the luminaire when the luminaire is assembled. A wireless node may be included with the luminaire. In some examples, the wireless node may be positioned on at least one of the housing assembly, the spacer, or the globe optic.

Abstract: A light fixture having a housing and a handle formed integrally in the housing. In some embodiments, the handle is positioned at a center of gravity of the light fixture so as to facilitate carrying of the light fixture and/or to reduce stress on the carrier's hand.

Abstract: Described is a light fixture system having a fixture housing with a base and sidewall that form a housing interior, and a continuous fire barrier element disposed within the housing interior. The continuous fire barrier element may include a central body and at least one flap extending from the central body. The at least one flap may be movable relative to the central body.

Abstract: An optical cover for a linear light source includes a portion of an optical material that forms a cross-section transverse to an axial direction. The cross-section curves so that its inner surface is substantially concave and its outer surface is substantially convex. The outer surface is substantially smooth, and the inner surface forms facets. Each of the facets refracts light, and connects with an adjacent facet. Each of the facets defines a peak height from the outer surface, and each pair of adjacent facets defines a valley height from the outer surface. The peak heights of all facets exceed the valley heights between adjacent pairs of facets, and the peak height of each selected facet does not exceed twice the valley height between the selected facet and a facet adjacent to the selected facet.

The luminaire also includes a carriage disposed within the opening, the carriage having a front face and first and second carriage edges on opposite sides of the front face, and one or more light sources arranged on the carriage. The luminaire further includes a tilting mechanism arranged such that the carriage is tiltable in at least two directions within the opening, and wherein when the carriage is tilted in a first direction from the central position, the first carriage edge remains proximate the first frame edge; and when the carriage is tilted in a second direction from the central position, the second carriage edge remains proximate the second frame edge.
