    Abstract: A controller for a disinfection system comprises a processor and memory comprising data accessible to the processor and firmware which when executed by the processor cause the controller to perform operations. The operations comprising causing a first light source to emit a white light into a space, and causing, during an emission of the white light, a second light source to emit pulses of visible cleansing light including one or more wavelengths of light that deactivate bacteria into the space at pulse times concurrent with the emission of the white light from the first light source. The controller controls the first and second light sources such that an intensity of a pulse emission of the visible cleansing light is higher than an intensity of the white light emission for all states of the space regardless of whether the space is occupied or unoccupied by a human.

    Abstract: An ultraviolet (“UV”) emission device may emit energy towards a movable surface of a conveyor system, A housing of the UV emission device may attach to a frame of the conveyor system. A lateral edge of the housing may extend across the moveable surface. The housing and a portion of the moveable surface may be inclined with respect to the frame. A barrier bracket of the UV emission device may support an absorptive barrier along the lateral edge, the absorptive barrier configured to contact the moveable surface. In a first position of the barrier bracket, the absorptive barrier contacts the moveable surface and the barrier bracket activates an interlock switch. In a second position of the barrier bracket, the barrier bracket deactivates the interlock switch. Responsive to deactivation of the interlock switch, a controller may provide a control signal to decrease power to the UV energy emission element.

    Abstract: A light fixture includes an electronic accessory module such as a wireless communication module, and a clip for mounting the accessory module to a panel of the light fixture. The clip includes features for snapping the accessory module to a panel of the light fixture, for example to a printed circuit board holding light emitting diodes or to a sheet metal panel that is part of the structure of the light fixture. The clip may hold the accessory module electronics away from any metal parts of the light fixture. In the case that the accessory module is a wireless communication module, this spacing may facilitate robust wireless communication.

    Abstract: An example luminaire includes a white light source (e.g. LEDs emitting white light in a region of the CIE color chart within three Macadam ellipses below the black body curve) and a violet light source emitting light in a wavelength range of approximately 380 nm to 450 nm (e.g. 405 nm LEDs) for deactivating bacteria, such as Methicillin-Resistant Staphylococcus Aureus (MRSA) on a surface exposed to illumination from the luminaire. A controller coupled to the sources pulses the violet light source at periodic intervals or at random times. When ON, the violet source emits light for deactivating bacteria at an intensity higher than the concurrent intensity of the white light.

    Abstract: An LED light engine includes a housing, one or more LEDs mounted on a printed circuit board and a retention feature engaged with the housing. The retention feature includes one or more of a torsion spring and a friction clip and is configured to engage an inside wall of a recessed lighting can, thereby retaining the LED light engine within the can. The LED light engine may also include a reflector and a lens retained within the housing, with the housing, reflector and lens forming a sealed chamber for protecting the LED components from external environmental conditions. Methods for retrofitting an existing recessed downlight fixture with an LED light engine include removing the existing light engine from the recessed lighting can and inserting an LED light engine into the can.

    Abstract: An example control system includes a set of light fixtures connected to a hub, where each light fixture includes a hub-communication device configured to communicate with the hub and a direct communication device configured to communicate directly with other light fixtures. Together, the light fixtures form a mesh network facilitated by the use of their direct communication devices. An external device communicates an instruction to a light fixture, and the instruction is propagated throughout the mesh network through communications among the light fixtures using their respective direct communication devices. As a result, each light fixture to which the instruction applies receives and complies with the instructions. The light fixtures are also configured to receive instructions from the hub, such that a light fixture is configured to receive instructions over dual networks.

    Abstract: A light fixture includes a housing containing a light engine, and a wireless baffle module. The wireless baffle module includes a baffle coupled to the housing and used for focusing light emitted from the light engine. The wireless baffle module further includes a wireless printed circuit board assembly coupled to an antenna. The wireless printed circuit board assembly receives and processes wireless signals from the antenna, and sends control signals to the light engine based on the wireless signals. The wireless baffle module may be coupled to a lighting system with an existing non-wireless module, or be used to replace a wireless baffle module with the same or different wireless protocol.
