The disclosure relates to support members for ceiling systems, such as those that can be formed into an interconnected grid to be suspended from a ceiling and support ceiling tiles. One aspect of the disclosure is a linearly-extending support member for a ceiling tile. The support member has a cross-sectional shape that includes a substantially vertical central web with a top end and a bottom end; at least one flange extending substantially horizontally from the bottom end of the web, the flange having an upper surface and a lower surface; and a bulb extending from the top end of the web, the bulb having a first side and a second side with a cavity therebetween, the bulb having an upper portion and a lower portion adjacent the top end of the web, wherein the entire lower portion of the bulb is narrower than the upper portion of the bulb and wider than the central web, the bulb comprising a series of spaced apertures formed therein through both the first side and the second side of the bulb, each aperture being disposed at least partially in the lower portion of the bulb, each aperture having an upper portion and a lower portion, wherein the upper portion of the aperture is rounded.

Disclosed is a suspended ceiling system, a securing member, and process of installing a patterned suspended ceiling system. The suspended ceiling system includes a grid system having first members and second members, and at least one substrate which extends below the grid system. The at least one substrate has an exposed surface and a concealed surface, and the at least one substrate has first sides and second sides which extend between the exposed surface and the concealed surface. Securing members attach to the concealed surface proximate the first sides, and the securing members have grid engagement members which secure the at least one substrate to the grid system. The securing members cooperate with the first members and the second members of the grid system to properly position the substrate and the spacing between adjacent at least one substrates is controlled.

An isolating hanger and method of making is disclosed for mounting a ceiling from an upper support. The isolating hanger comprises a one piece bendable wire having a spring shape defined between a first and a second wire end. The spring shaped is tempered for transforming said spring shape into a resilient spring. The remaining bendable wire ends affix the upper support to the ceiling for isolating vibration between the ceiling and the upper support.

A system includes an anchor body comprising a head and a hollow chamber shaft coupled to the head. The system also includes a housing sleeve configured to support the anchor body. The housing sleeve includes one or more fasteners pre-threaded into a base of the housing sleeve, and the housing sleeve comprises an arch configured to adapt to a ridge of a metal deck.

A luminaire structure, comprises a plurality of housing segments, each with at least one lighting zone, and configured to be assembled to form a support structure defining at least one panel supporting zone for supporting at least one acoustic panel removably attached thereto, wherein each of the lighting zones in the support structure is oriented to be adjacent the at least one acoustic panel, and operable to receive a lighting module to deliver light to an interior space.

A configurable lighting assembly for use in suspended ceiling grid systems which provides novel T-Bar mounting options. The lighting assembly comprises two configurable length linear lighting modules in a novel parallel arrangement. End plates support, and enclose longitudinal ends of the elongate body of each linear lighting modules and are used to set a configured width and functional gap spacing of the linear lighting modules. The end plates further connect and support the lighting assembly when fixed or mounted or removably to T-Bars positioned at either or both perpendicular and parallel alignment angles.

Lighting assemblies with various embodiments of end plates and linear lighting modules are presented, each with novel mounting characteristics. In some cases the lighting assembly mounts perpendicularly on its end and spans the gap between two T-Bars. In other cases the lighting assembly mounts longitudinally on a single T-Bar. Finally, embodiments are shown where the lighting assembly mounts both perpendicularly and longitudinally to different T-Bars in a ceiling grid layout.

The lighting assembly further comprises a novel arrangement of LED light sources, transmissive optical elements, light shaping lenses, reflectors and other functional components supported and housed within the elongate body of each linear lighting module. The transmissive optical elements may be backlit or edgelit from one or two sides and aligned horizontally or tilted relative to the ceiling grid plane. The lighting assembly can provide a range of useful symmetric, asymmetric and tilted non-lambertian lighting distributions.

An anchor comprises a conduit for receiving a flexible elongate member therethrough. The conduit has an internal region and first and second openings. The flexible elongate member can extend through the first and second openings and through the internal region of the conduit. The conduit is a curved, substantially U-shaped elongate tubular member.
