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.

The present disclosure discloses a mounting assembly for an optical element of a lighting lamp, including a base, a top frame and at least two side frames, one end of each of the at least two side frames is connected to the base and the other end is connected to the top frame; the at least two side frames, the base and the top frame enclose a mounting space for fixing the optical element, and the at least two side frames are configured to be distributed around the optical element and are configured to be connected to a side edge of the optical element. The present disclosure further discloses a light source module and a lighting lamp.

A lighting assembly is provided that includes a light fixture in combination with a support grid such as a drop ceiling t-bar. The light fixture can be configured to use a t-bar as the main form of support. The light fixture can be push-fit onto a t-bar or use a clip to join two or more portions of the light fixture to an installed t-bar. Once attached to the T-bar, the light fixture itself can provides support for a ceiling tile. Various embodiments are provided which achieve a variety of light distributions useful in typical illumination applications. Both recessed and suspended fixture types are achieved in various embodiments which are particularly well suited for LED lighting.

A light emitter assembly includes a base body, a base electrical connector disposed on the base body, and a light emitter disposed on the base body and electrically connected to the base electrical connector. The light emitter assembly also includes a light housing disposed on the base body and housing the light emitter, and a power receptacle and/or a communication receptacle disposed on the light housing and electrically connected to the base electrical connector. The light housing is configured to allow passage of light therethrough.

A ceiling suspension, including a first member, including physical and electrical connectors for being physically and electrically fixed to the ceiling, a second member, including physical and electrical connectors, for being physically and electrically connected to an electrical appliance, where the first and second members include complementary electrical connectors, being configured for electrically connecting one another upon completing horizontal sliding of the second member in relation to the first member being fixed to the ceiling, and where the first and second members include complementary physical connectors, being configured for supporting the second member by the first member upon completing the horizontal sliding of the second member.

A lighting assembly includes a light transmissive substrate extending along a length and including a light emission portion including opposed first and second major surfaces spaced apart from one another in a thickness direction, an inner edge surface extending between the first and second major surfaces in the thickness direction, and an outer edge surface opposed the inner edge surface and extending in the thickness direction. An extension portion extends from the light emission portion proximate the second major surface in the thickness direction. A light source is attached to the extension portion. A light head includes a housing, a primary light source attached to the housing, and the lighting assembly as an auxiliary lighting assembly. The housing includes a channel in which the auxiliary lighting assembly is retained.

An integrated lamp and a method of manufacturing an integrated lamp. The integrated lamp includes a main lighting lamp body and auxiliary lighting lamp bodies that can be assembled to the main lighting lamp body in a plug-in way. The auxiliary lighting lamp bodies can be rotatably adjusted relative to the main lighting lamp body.

A light fixture includes a housing, a controller, and a lighting module. The housing includes a first portion and a second portion. The second portion of the housing defines a window. The controller is at least partially disposed within the first portion. The lighting module is at least partially disposed in the second portion and includes a submount and a plurality of light emitting diodes coupled with the submount. The plurality of light emitting diodes are configured to project light through the window. The housing defines a passageway that extends between the first portion and the second portion such that the lighting module and the controller are physically spaced from each other via the passageway. The passageway is configured to allow ambient air to flow through the housing between the first support portion and the second support portion to facilitate cooling of the lighting module and the controller.

A ceiling fan assembly or similar air-moving device can include a motor for rotating one or more blades to drive a volume of air about a space. The ceiling fan assembly can include a housing including a first portion and a second portion, whereby the first portion selectively couples to the second portion. The housing can further include one or more sealing or deflecting components.

A light fixture includes a housing, a controller, and a lighting module. The housing defines a first and second portions. The second portion defines a window. The controller is at least partially disposed within the first portion. The lighting module is at least partially disposed in the second portion. The lighting module includes a submount, a plurality of light emitting diodes, a lens cover, an encapsulating material, and a protective coating. The plurality of light emitting diodes is coupled with the submount and is configured to project light through the window. The lens cover includes an exterior surface and overlies the plurality of light emitting diodes and the submount such that the lens cover and the submount define an interior therebetween. The encapsulating material substantially fills the interior. The protective coating is provided over the exterior surface.
