A laminar flow diffuser with integrated lighting has a frame for supporting an air plenum and a lower housing. The air plenum receives conditioned air from a source of conditioned air. The lower housing is attached to the bottom of the plenum. An aperture plate damper installed below the top plenum regulates the flow of air from the plenum through the laminar flow diffuser. A clear or translucent the perforated diffuser face forms the outlet from the lower housing to the room below. LED strips are positioned around the inside periphery of the lower housing. A perforated reflector panel is position below the aperture plate damper and above the LED strips to spread the light from the LED strips across the perforated diffuser face.

In one aspect, a troffer light fixture includes a troffer body shaped to reflect or disperse light from a light source that includes LEDs attached to a first side of the troffer body. The troffer body includes two or more vents that are configured to pass air from the first side of the troffer body to open space on a second side of the troffer body for a duct-less HVAC air intake.

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 or outside 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.

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.

Disclosed is a lighting tower (100) with a Light Emitting Diode (LED) (106). The lighting tower (100) comprises a Base Unit (102), an inflatable balloon (104), a blower (108), and a stabilizing rod (114). The inflatable balloon (104) is coupled to the Base Unit (102). The LED array (106) coupled to a top end of the inflatable balloon (104) with inward facing of the LED (106) in the inflatable balloon (104). In one aspect, the blower (108) lifts up the inflatable balloon (104) with the LED array (106). In another aspect, the blower (108) simultaneously controls a temperature at a junction of the LED (106).

A combination light and pressure relief vent is disclosed which includes a housing, a valve assembly, and a light assembly. The housing include a multi-radial positionable valve body, port tube, and an outside louver. The valve assembly includes a low positive pressure exhaust valve, a high positive pressure exhaust valve, a low negative pressure intake valve, and a high negative pressure intake valve. The light assembly includes a heat sink casing which defines a heat chamber and which includes a projection extending into the heat chamber. The casing is coupled to an LED module wherein heat generated by the LED module is transferred through the casing to the heat chamber to warm the valve assembly.

A ventilation grille has an annular shape, and includes a panel and a lamp unit. The panel includes an intake opening provided around a central part of the annular shape, and a frame provided around the intake opening. The lamp unit is provided in the central part of the annular shape. The panel has a structure for attaching and detaching the lamp unit.

Aspects of the present disclosure include an integrated lighting system including a casing configured to detacheably couple from a conventional air vent, a motion sensor configured to detect a presence of a person, a light source, and a processor configured to receive, from the motion sensor, an indication in response to the motion sensor detecting the presence of the person, and send, to the light source, an activation signal to activate the light source in response to receiving the indication.

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.

A unitary dining unit combining table functions and seating, which dining unit solves the above stated problems, is disclosed. The novel dining unit may be oblong, with opposed convex surfaces, to enable occupants to easily view one another, and to assist in fitting the table or desk efficiently within a square or rectangular room of a building. The unitary dining unit integrates a work surface, e.g., a table or desk surface, with seating. The integrated seating has support arms connecting the seating to the table portion, and maintaining all portions of each seat above the floor, thereby leaving space for and facilitating floor cleaning in the area of the furniture. A perimetric wall serves as an aesthetic skirt concealing seat anchorage elements and other utilitarian components from external view.
