A dual LED light fixture is comprised by a lower LED light source housing and an upper LED light source housing. A lower LED light source is mounted in the lower light source housing to generate downlight. An upper LED light source is mounted in the upper LED light source housing and remote from an outer circumferential light transmitting outer side area of the upper light source housing and from which is emitted side light illumination. An LED power supply and light control circuit mounted in the LED light fixture and adapted for connection to a power source. The LED light power supply and control circuit has a dimming circuit and a lower and upper driver current supply circuit. A switch is operative to connect driver current to the upper LED light source when actuated to an “on” position and to disconnect driver current to the upper LED light source when in a normal “off” position. The switch is operative for engagement to its “on” position when desirable to provide drive current to the upper light source and illumination from both the lower and upper LED light sources of the LED light fixture. Various embodiments of the LED light fixture is described.

A walkable ceiling system is provided that includes ceiling panels each having opposed first and second edges and opposed third and fourth edges. The ceiling panels are arranged in a grid pattern where the third edge of a ceiling panel abuts the fourth edge of an adjacent ceiling panel and the first edge of a ceiling panel is spaced apart from the second edge of an adjacent panel. A plurality of turnbuckle assemblies each include a plate secured to corners of four adjacent ceiling panels, and a turnbuckle secured to the plate for suspending the ceiling panels. The light fixtures include: a lens attached to the first edge of a ceiling panel and second edge of an adjacent ceiling panel; a top plate secured to adjacent ceiling panels; a wiring raceway attached to the top plate; and LEDs attached to the wiring raceway for projecting light through the lens.

An overhead lighting fixture containing both visible light sources and UV light sources is disclosed herein. UV light can sanitize/disinfect the surrounding environment after the environment over a period of about 30-45 minutes. In this way, viruses, germs, bacteria, mold, and the like can be destroyed to clean the air and/or surfaces (e.g., furniture). Accordingly, embodiments of the present invention provide a controllable UV lighting assembly that can produce UV light to sanitize/disinfect an area and can be automatically disabled to prevent UV light exposure to those in the area using a motion sensor. The lighting assembly can produce visible light while the UV light source is disabled. According to some embodiments, the duration of UV light production is controlled by a timer for power savings.

An elongate tubular lighting assembly having a body with a length between spaced first and second ends. The tubular lighting assembly has a source of illumination and first and second connectors respectively at the first and second body ends. The first connector has cooperating first and second parts having first and second surfaces. The first and second connector parts are configured so that the first and second surfaces are placed in confronting relationship to prevent separation of the first and second connector parts with the body in an operative state as an incident of the first connector part moving relative to the second connector part from a position fully separated from the second connector part in a substantially straight path that is transverse to the length of the body into an engaged position.

Described herein are components, systems, and methods of use of an integrated sterilization system comprising a pass-through logistics cabinet, an ozone sterilization system, a floor sterilization robot, and systems for controlling such components. An integrated operating room sterilization system will allow mitigation or elimination of risks (e.g., infrastructural risks (e.g., OI risks), procedural risks (e.g., risk of infection and contamination) that are associated with a setting in a healthcare environment. The elimination of clutter, control of major components under a unified and intuitive user interface, and the logical elimination of potential accumulated risk events (e.g., OI risks) and procedural risks are deliberately addressed, in whole or in part, by the present disclosure. The present disclosure describes the following: a pass-through logistics cabinet, an ozone sterilization system, a floor sterilization robot, and systems for controlling such components.

An integrated and modular air and lighting plenum that is the primary directional lighting mounting apparatus and laminar flow diffuser of an HVAC system in a healthcare setting. The plenum provides laminar air flow from the ceiling to the room in which it is located in accordance with HVAC requirements for healthcare environment settings, by using a plurality of cylindrical airflow outlets. The use of cylindrical airflow outlets promotes laminar airflow by reducing sharp boundaries that induce turbulence (e.g., the corners of rectangular or square outlets) and creates a highly sterile environment around the patient and staff in the operating room. The surgical lights used in the integrated air and lighting plenum allow the beam direction, spot size, focal point, brightness, and color temperature of the emitted light to be controlled.

A surface mounted lighting is disclosed and includes a pair of copper foils/strips extending along a length of a removable guide tape. The copper strips are provided with adhesive on their opposite side for securement to the intended surface (e.g. ceiling, wall, etc.) in a room. One or more lights can be adhered to the surface secured copper tape, after the guide tape is removed, to create an electrical connection/communication between the tape and light(s). An electrical controller can also be adhered to the copper tape preferably similar to how the lights are secured to the copper tape to create an electrical connection/communication between the electrical controller and the copper tape and for sending power to the light(s) when the electrical controller is turned on or otherwise instructed. The electrical controller is preferably electrically connected to an electrical outlet within the room for receiving power. The disclosed lighting system is safely and easily installed without any drilling into walls or ceilings.

A spine for a troffer light fixture is provided. The spine is configured to receive omni-directional LED bulbs. The spine comprises: a base, a first wall, a second wall, and first end walls defining a light chamber shaped as a trough. Interior angles between the first wall, second wall, and base is 90-100 degrees respectively. The second wall defines a plurality of apertures each having a central axis arranged generally parallel in a linear arrangement. The apertures include: a pair of flanking apertures, the axis of each flanking aperture positioned 80-110 mm from one of the first end walls, and at least one interior aperture, the axis of each interior aperture positioned 135-145 mm from the axis of an adjacent aperture. Each of the plurality of apertures provides an opening through which an omni-directional LED bulb can extend parallel to the base to engage a socket mounted on the spine.
