A wall- or surface-mounted light fixture with a housing containing one or more external visible light sources to illuminate the space where the light fixture is mounted, one or more UV emitters inside the housing to destroy bacteria and pathogens, and one or more fans inside the housing that recirculate the air in a space and subject the air to the UV radiation inside the housing, destroying bacteria and pathogens in the air passing though the housing.

Embodiments of the invention provide a lighting and ventilating system including a main housing. The main housing can include an inlet through which air can be received within the main housing and an outlet through which the air can exit the main housing. A fan wheel can be supported in the main housing and it can be operable to generate a flow of air. A grille can be coupled to the main housing and the grille can comprise at least one aperture. The system can include a plate coupled to the grille and the plate can include a recess. Also, a set of illumination devices can be at least partially disposed within the recess.

A ceiling-mounted decontamination unit with one or more internal decontamination sources, which may be UV-C emitters, inside a housing with a hingable panel for access to the internal space of the housing for maintenance and repairs, and one or more fans inside the housing that re-circulate the air in a room and subject the air to the germicidal internal decontamination source inside the housing, decontaminating the air passing through the ceiling-mounted decontamination unit's internal space and destroying viruses, bacteria, and other pathogens. The ceiling-mounted decontamination unit draws the air in from the room or area where the ceiling-mounted unit is installed, subjects the air to the internal decontamination source destroying pathogens, and returns the decontaminated air back to the same room or area from which the air is drawn. An optional luminaire or external decontamination source may be attached to the room- or area-facing exterior of the ceiling-mounted decontamination unit.

A light system includes a main body defining an internal chamber and a lighting assembly secured to the main body, wherein the lighting assembly comprises at least one light unit configured to emit light. The light system further includes a fan configured to generate an airflow and an airflow circuit configured to direct the airflow out of the main body of the lighting assembly. The light system also includes a tilt detection unit configured to detect a tilt angle of the lighting assembly and to generate a control signal to cause a speed of the airflow generated by the fan to change based at least on a detected change in the tilt angle of the lighting assembly.

An activities unit combining a table or other horizontal surface with seating units is shown and described. Seating units may include both permanent or fixed individual seating units and also, at least one additional seating unit movable between a stowed position to a deployed position. Both permanent or fixed seating units and also stowable seating units may each be supported on the activities unit by an arm above floor level. This enables ready cleaning of a floor surface on which the unitized table is placed without having to move seating units out of the way. Construction of the unitized table enables utilitarian components and features which may be deemed unsightly to be concealed, for example, by wood paneling both at a table top and also a depending wall. The table top may overhang the depending wall.

A ceiling element including a base adapted to be mounted in a ceiling of a room, thereby defining a room space under the base and a ceiling space above the base, is provided. The ceiling element includes a battery container adapted to receive a battery and arranged at the base such that it is located in the ceiling space when the ceiling element is mounted in the ceiling. The ceiling element further includes a conduit arranged to convey air between the room space and the ceiling space and/or the battery space when a temperature of the room space is different from a temperature of the ceiling space and/or a temperature of the battery container. A method of thermal management of a battery received in a battery container located in a ceiling space is also provided.

An integrated ventilation and illumination system includes a ventilation assembly, a light fixture assembly, and an adaptor. In an installed position, the ventilation assembly is installed in a ceiling of a room of building structure to provide ventilation for the room and the light fixture assembly is mounted in a low-profile configuration relative to the ceiling. The adaptor spans and obscures an inlet opening of the ventilation assembly and includes at least one opening that allows for the passage of air through both the adaptor and into the inlet opening. A mounting bracket is coupled to both the adaptor and the light fixture assembly in the installed position, where the fixture is offset a first critical distance from the adaptor to define an air flow gap that allows for air flow around the light fixture assembly, through the opening in the adaptor and into the internal region of the main housing. The first critical distance is purposely sized according to operating parameters of the blower of the ventilation assembly to provide a sufficient flow rate of intake air and acceptable sound levels during operation of the ventilation and illumination system.

An actuator includes a housing. The housing includes a lower body. A cover assembly is coupled to the lower body. The cover assembly includes a transparent indicator disposed along a periphery of the cover assembly and adjacent to the lower body. A circuit board is disposed within the housing. The circuit board includes at least two illuminating devices disposed diagonally opposite to each other. The at least two illuminating devices illuminate the transparent indicator.

The present invention relates to a general-purpose dehumidifying apparatus in which a housing having a dehumidifying member therein is applied to an object to be dehumidified (an electric light (such as a street lamp, a vehicle lamp, etc.), an outdoor or indoor electronic enclosure (such as power distributing equipment, communication equipment, security equipment, a solar system, etc.), and the like), and the dehumidifying apparatus removes internal moisture through an outer valve that opens and closes an outer communicating part of the housing (by closing the outer valve) in a case where the temperature of the object to be dehumidified is low and discharges the moisture of the dehumidifying member to the outside by opening the outer valve when the temperature in a lamp module rises in a case where the temperature of the object to be dehumidified is high. The dehumidifying apparatus, according to the present invention, comprises: a housing installed in an object to be dehumidified and having inner and outer communicating parts connected to the outside; a dehumidifying member mounted in the housing; and an outer valve that opens and closes the outer communicating part of the housing.

The T-bar includes an elongate rigid spine extending between terminal ends including either a fixed anchor or adjustable anchor for attachment to adjacent T-bars or other supports. An upper heat sink is provided on an upper portion of the spine to enhance heat transfer from the T-bar to air surrounding upper portions of the T-bar. A light housing is provided on a lower portion of the T-bar which is configured to support a lighting module therein, such as a light emitting diode (LED) light. A lower heat sink is provided above this light housing and integrated into a rest shelf which supports ceiling tiles adjacent the T-bar. A power supply is provided which can be removably attached to the T-bar and provide appropriately conditioned power for the lighting module.
