An assembly for an opening through a member has a body and a first spring retention assembly coupled to the body. The first spring retention assembly has a first coil spring at least partially disposed within a first spring housing. The first coil spring has a first end extending through the first spring housing and is coupled to the body. The first coil spring is extendable from and retractable into the first spring housing.

A mounting profile for lighting system of suspended ceiling, which comprises a comprehensive triple-section aluminium profile, where repositionable wireless luminaires fitted with magnets can be used on the mounting profile and comprises devices for fastening stretch ceiling material as well as other types of suspended ceiling materials thereto.

A singular passive/active ventilation and lighting apparatus for enclosed spaces. The apparatus is adapted to harness solar energy through a cover which also directs light down through a reflective tube. The apparatus provides a passive vent which is fluidly coupled to the same reflective tube. As the reflective tube couples the external environment with an enclosed space, passive/active ventilation and passive/active light is directed to the enclosed space. The solar energy is directed to other components supported by the singular apparatus, like the active lighting and active ventilation fan as well as a wireless router, an electric charger and power storage unit for storing the harnessed solar energy and powering the active components.

In a suspended ceiling a housing is provided including a light located within an interior chamber having a lower opening. The housing includes lateral sides with slots therein which can receive fasteners coupled to ends of other T-bars. Ends of the housing can include fasteners, such as tabs or clips, which attach ends of the housing to adjacent supports, such as other T-bars within the suspended ceiling. In one embodiment, the housing has a constant cross-sectional form. The cross-sectional form can include lateral sides defined by lateral cross-tees with a vertical spine and lateral rest shelf upon which an edge of the ceiling tile can be supported. A central cross-tee can optionally be provided extending down from upper portions of the housing and between diagonal spans on upper lateral portions of the housing. One or more diffusers span the lower opening of the housing.

A recessed lighting fixture comprises a generally annular body having a central cavity in the form of a partially spherical socket. There is a lighting support member having a partially spherical exterior portion which is closely fitted within the partially spherical socket of the annular body. The lighting support member is pivotable relative to the annular body, but air flow between the partially spherical socket of the annular body and the partially spherical exterior portion of the lighting support member is substantially restricted. There may be a light source mounted to the lighting support member adj acent a bottom thereof. The light source may be a light-emitting diode.

A lamp installation structure of a ceiling fan has a first base connected to a fixing seat of the ceiling fan and a second base connected to a lamp. The first base is provided with a plurality of positioning members. The second base has grooves and guide rails corresponding to the positioning members for insertion of the positioning members. The guide rails are provided with a plurality of elastic members to elastically press against the positioning members. Thereby, through the positioning members being retained to the guide rails, the lamp installation structure of the ceiling fan has the advantages of quick installation and increased stability of the ceiling fan.

A junction box cover assembly for attachment over an opening in an electrical junction box allows for a concealed connection to avoid detracting from the lighting fixture. The assembly includes a cover plate capable of being mounted to a junction box, the cover plate having an opening there through defined by a first threaded collar extending from the cover plate, a hub having a flange radially extending from a periphery of a second threaded collar defining a passage and configured to attach to the first threaded collar of the cover plate, and a circular insert detachably connected within the passage defined by the threaded collar, the circular insert having an opening for passing electrical wiring from the junction box through the passage, out the insert opening and to a light fixture. The cover plate and the radially extending flange somewhat sandwich a surface, such as drywall or wallboard, and the flange is configured to permit covering with spackling paste or joint compound to conceal the flange.

A lighting assembly includes an upper mount having a pan gear and a plurality of indicator flanges. A lower mount is operably coupled to the lower mount and includes a pan motor and a tilt motor. A printed circuit board is operably coupled to the upper mount and includes a plurality of sensors. At least one sensor is selectively and operably coupled with the plurality of indicator flanges of the upper mount. A light module is operably coupled to the lower mount and includes a tilt gear operably coupled to the lower mount. A controller is operably coupled to the printed circuit board, the pan motor, and the tilt motor and is configured to rotate the lower mount and the light module via the pan motor and is configured to tilt the light module via the tilt motor.
