A combined ventilation and illumination system includes a ventilation assembly, a light fixture assembly, and a connector assembly. In an installed position, the system is installed above a ceiling of a room of building structure (e.g., a residence or workplace) to provide ventilation for the room. The system couples a light fixture to ventilation assembly below the ceiling. In the installed position, an air flow cavity is defined between the light fixture and the ceiling, where the cavity allows for air flow around the light fixture and into the ventilation assembly for eventual exhaust beyond the room in which the system is installed. The cavity includes a first critical distance that is sized according to operating parameters of a blower of the ventilation assembly to provide an adequate flow rate of intake air and to provide acceptable sound levels during operation of the system.

A flush-mounted, in-ceiling exhaust fan grille for attachment to an exhaust fan housing includes a planar integration flange forming a perimeter of the grille. The integration flange includes a plurality of through holes along the perimeter. An insert may be configured for insertion within the perimeter of the integration flange. A light module may be configured to join within a central portion of the insert while maintaining an opening between an entirety of the light module and the insert. At least one spring may be attached to the insert on a first end and attached to the fan housing on a second end, wherein the at least one spring applies a force drawing the insert towards the fan housing. An exhaust fan may be provided to draw air into the fan housing through the opening between the light module and the insert to be exhausted for proper ventilation.

The invention relates to a device (1) for lighting and for disinfecting a gaseous mixture (G) comprising: —a first ventilation device (2) designed to suck a gaseous mixture through a suction port (3) of the first ventilation device; —a second ventilation device (4) designed to discharge a gaseous mixture through a discharge port (5) of the second ventilation device; —a disinfection duct (6) connecting the suction port (3) to the discharge port (5) and comprising a plurality of sources of disinfection radiation (7) arranged along the disinfection duct (6), each source of disinfection radiation being configured to emit disinfection radiation intended to disinfect the gaseous mixture (G) sucked into the disinfection duct (6); —a plurality of sources of illuminating radiation (8) arranged along the disinfection duct (6) on an outer surface of the disinfection duct (6) and intended to emit illuminating radiation; and—a housing (9) comprising a plurality of surfaces opaque to the disinfection radiation.

The light device with integrated scent atomization module includes a lighting module, a scent atomization module, and an airflow module. The lighting module includes a lighting element producing light, a socket element to a side of the lighting element, and a cap element to a side of the socket element. The scent atomization module is detachably joined to the socket element, and includes an atomizer, and a container adjacent to the atomizer. The airflow module is configured inside the lighting module. The composite lighting device can be mounted to an ordinary lamp socket and substituted for an ordinary light bulb. Through the scent atomization module's atomization of the essential oil stored in the container, scent is released outside of the composite lighting device to achieve air purification. The heat from the lighting element may also accelerate and make more fully the atomization of the scent atomization module.

According to an aspect of this disclosure, a ventilation and lighting system including a main housing having an inlet opening and a discharge opening, a blower and motor assembly disposed within a housing and operable to move air through the inlet and outlet, a grille configured to be located at the inlet opening, the grille having a cavity and a plate defining a plurality of apertures through which air may move, and one or more lighting elements arranged within the cavity and an optical component covering the cavity. The system is arranged such that light developed by the one or more lighting elements mixes within the cavity and transmits through the optical component covering the cavity, and the system further includes a controller that coordinates operation of the blower and motor assembly and the one or more lighting elements from a remote location.

The present invention relates to an electrical device provided in or attached to an air duct. The electrical device comprises a housing and an electrical body attached to the housing which extends at least partially into the housing and is adapted to connect a power source to an electrical element. The housing is provided with a passage for allowing air to flow between an end of the housing to be turned towards a room of the building and an end of the housing to be turned towards the air duct and for allowing air to flow in the space between an inner housing side and an outer side of the electrical body.

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.

A lamp includes an air supply and a lighting module. The air supply includes an air blower and an annular housing, the annular housing defines an annular region and has an inner ring surface, an outer ring surface, a first end surface and a second end surface which are connected with the inner ring surface and the outer ring surface and face away from each other. The lighting module is disposed at a side of the annular housing which is close to the first end surface and is located within a projection range of the annular region at the side, and the lighting module emits light rays towards the side faced by the first end surface.

An air terminal device with integral light fixture for a clean room, comprising a housing having a cover panel comprising at least one opening, a light fixture for providing light outside of the air terminal device, an air chamber configured to receive air and to discharge air out of the air chamber, wherein the air is configured to be transferred through the at least one opening in the cover panel, wherein the light fixture is arranged inside the air chamber, and the cover panel comprises at least one light fixture opening, in which the light fixture is integrated.

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.
