A modular suspended ceiling assembly is provided having by multiple panels formed by spaced from each other first and second connecting walls, with first and second main brackets connected to the first connecting wall. First and second auxiliary brackets connected to the second connecting wall. A plurality of suspension members with each suspension member being connected to a hollow support structure. A guide passes through the hollow support structure. A module is formed by adjacent panels supported by the single guide passing through the support structure and accompanied by engagement of the main and auxiliary brackets.

A optically transmissive component is configured within a light fixture to provide benefits in brightness uniformity and visual appearance with the use of a light scattering extension portion that provides light scattering of light emitted from near an input edge of a light guide or other edgelit optical element. The sequential propagation of light through both the extension portion and main portion of the optically transmissive component significantly reduces the higher brightness and uneven “hotspotting” type visual defects typically produced near the input edge of an edgelit optical system. With appearance constraints removed or reduced, edgelit light fixtures with higher output, higher efficacy, and/or simplified edgelit optical components are enabled. Embodiments include the use of the extension portion of the optically transmissive component extension to mechanically position and retain an edgelit optical element within a light fixture.

Disclosed embodiments relate to a combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. Disclosed embodiments further include ceiling tiles with a built-in fan and/or LED lighting. The disclosed systems may include one or more UV-C light sources which irradiate contaminants as air flows through the UV-C unit. The UV-C unit is mounted on either a universal mounting mechanism or a mobile support unit to provide mobility to the UV-C unit.

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.

An architectural fixture assembly including a generally U-shaped first beam having a bottom side, a first side, a second side, and a first end. Interior surfaces of the first, second, and bottom sides of the first beam define an interior portion. A connector includes a plate, and a connection key extending away from the plate. The interior surfaces of the first and second sides each include a generally V-shaped alignment notch disposed generally adjacent to the first end of the beam. The connection key includes a pair of generally V-shaped sides disposed on opposite sides of the connection key, and each generally V-shaped side is configured to slidably engage one of the generally V-shaped alignment notches.

A luminaire is mechanically attached to a mounting structure, mounted and positioned to illuminate a space adjacent to the luminaire The luminaire comprises at least one light source mounted on a substrate, and a thermal bus transporting heat from the substrate to a heat sink that is veiled from view. The at least one light source and the substrate are exposed to, and illuminate, the space. Another disclosed luminaire includes LEDs and a fixture on which the LEDs are disposed. The fixture is configured to install onto a grid of a suspension ceiling by hooking or clamping onto the grid of the suspension ceiling with the LEDs disposed on the installed fixture facing downward from the suspension ceiling.

A system for creating an enclosed room, such as an office, in an open space that has a floor and a ceiling. The system includes a support frame that is self-supported on the floor of the open space. The support frame includes a series of head rails supported by a series of vertical columns resting on the floor. The vertical columns support a series of wall panels and the head rails support a ceiling such that the ceiling is supported by the support frame independent of the wall panels. The ceiling of the enclosed room is created by a series of ceiling panels and at least one air intake panel and at least one air exhaust panel. The air exhaust panel includes an exhaust fan that removes air from within the enclosed room and draws fresh air into the enclosed room. The ceiling can include a plurality of adjustable louvers and lighting.

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.

A mounting assembly is provided for quick and easy attachment to engineered joists. The mounting assembly includes a brace assembly and a mounting bracket. The mounting assembly may also include an electrical box. The brace assembly is an adjustable member that extends between flanges of engineered ceiling joists. The brace assembly has two low profile end caps that can engage the flanges of engineered ceiling joists and apply a force against the flanges when tightened. The mounting bracket is connected to a hanger body of the brace assembly by a snap fit and the electrical box is attached to the mounting bracket.

A ceiling façade system includes: a ceiling tile including an interior panel defining a first edge extending along a first side of the ceiling tile and a second edge extending along a second side of the ceiling tile opposite the first edge, a heating element, and an insulator layer arranged over the heating element opposite the interior panel; a first receiver extending along and configured to support the first side of the ceiling tile on a linear lighting track arranged on a ceiling structure and configured to locate the first edge of the interior panel adjacent and partially concealing the linear lighting track; and a second receiver extending along and configured to support the second side of the ceiling tile on a linear seam track arranged on the ceiling structure, the linear seam track laterally offset from the linear lighting track.
