Abstract: A system for disinfecting an enclosed space includes a housing, ultraviolet (UV) emitters, a sensor to detect occupancy in or entry into an enclosed space, a UV directing mechanism, and a controller. The housing includes an air flow passageway. When the UV directing mechanism is in the closed state, the UV emitters are positioned in the air flow passageway and transmission of UV electromagnetic radiation into the enclosed space is substantially blocked. UV electromagnetic radiation is transmitted into the enclosed space when the UV directing mechanism is in the at least one open state. Disinfection operations can be activated when the UV directing mechanism is in the open state or the closed state. When the UV directing mechanism is in the open state, the disinfection operation is activated when the sensor indicates no occupancy in or no entry into the enclosed space.

Abstract: Light systems and light fixtures are described herein. In one embodiment, a light system may include a light fixture, a first diffuser attached to the light fixture, where the first diffuser and the light fixture define a cavity, a first LED producing ambient light within the cavity, and a second LED producing directional light in the cavity, where the first diffuser is adapted or configured to receive the ambient light and the directional light and emit the ambient light and the directional light external to the light system. In another embodiment, a light fixture may include a first LED subsystem including a first LED and a diffuser, the first LED subsystem adapted or configured to produce ambient light, a second LED subsystem including a second LED and a reflector, the second LED subsystem adapted or configured to produce directional light, where the directional light passes through the diffuser.

Abstract: A system for disinfecting an enclosed space includes an ultraviolet (UV) disinfection assembly, a sensor to detect occupancy in or entry into the enclosed space, and a controller. The UV disinfection assembly includes UV emitters. The controller controls operation of the UV emitters to carry out disinfection operations, each of a predetermined UV dose. The controller activates a disinfection operation in a first mode when: (1A) the sensor indicates no occupancy in or no entry into the enclosed space. The controller activates a disinfection operation in a second mode when: (2A) the sensor indicates no occupancy in or no entry into the enclosed space, and (2B) there is a qualified human input through a human-machine interface (HMI) in communication with the controller. The controller suspends or deactivates the disinfection operation when the sensor indicates occupancy in or entry into the enclosed space.

Abstract: A modular lighting system for attachment and removal of light sources is described herein. In one embodiment, the system may include a first LED light segment adapted or configured to produce ambient light, a second LED light segment adapted or configured to produce directional light, an installation track adapted or configured to connect to the first LED light segment and the second LED light segment along a length of the installation track, a power source adapted or configured to provide power, via the installation track, to the first LED light segment and the second LED light segment when the first LED light segment and the second LED light segment are connected to the installation track, where the first LED light segment and the second LED light segment are further adapted or configured to be separately controllable and positionable along the length of the installation track.
