The present invention is directed to ceiling panels formed from a porous scrim that is coupled to an acoustical substrate using a scrim attachment system that includes an adhesive.

This disclosure relates to an assembly that is configured to be installed or integrated into a suspended grid ceiling.

A light fixture delivering electrically controlled lighting distributions for mounting within an installed panel system typically used in ceiling and wall constructions and incorporating acoustic, drywall or wood panels. The light fixture can provide low-glare or wide spread “batwing” ambient light or more directional wall wash, task and accent lighting. The light fixture comprises one or more LED boards and an optical element which can be back-lit or edge-lit. The light fixture body is configurable, comprising a 3-dimensional extruded elongate body with its ends cut at a configured angle. The body typically comprises additional side support features that support and enclose the edge of installed panels. In the case of a T-bar based ceiling grid system the side support features may also replicate the function and appearance of T-bar horizontal and vertical portions. The body comprises features to retain and align LED boards, reflectors and a back-lit or edge-lit optical element. In the edge-lit configuration the optical element may also be a light guide. The edge-lit design also enables the height of the lighting assembly body to be equivalent to or less than the height of T-bar main beams or cross tees. This is very important in applications where there is zero or little available plenum space above the ceiling grid. Because the lighting assembly can also provide structural support within the installed panel system it can replace one or more T-bars and can also be used to connect one or more T-bars or other structural grid elements. The lighting fixture can be mounted at an oblique or diagonal angle to the typical square grid layouts, or in a corner of a ceiling grid T-bar cell at the intersection of one or more T-bars. Additionally, more than one elongate bodies can be connected to form square, crosses, curves or arcs or more complex shapes. The electrical power may additionally be configured to control lighting distributions of the fixtures independently of one another.

An end cap for a ceiling panel of a ceiling system. The end cap includes a face plate having an inner surface, a bottom edge, a top edge, a first side edge, and a second side edge. A first insertion plate extends from the inner surface of the face plate at the top edge of the face plate. A second insertion plate extends from the inner surface of the face plate at the bottom edge of the face plate. A concealment portion extends from the inner surface of the face plate along the first and second side edges of the face plate. The concealment portion may include an upper section positioned above the first insertion plate and spaced from the first insertion plate by a first gap and a lower section of positioned below the second insertion plate and spaced from the second insertion plate by a second gap.

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 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.

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.

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 ceiling tile for a suspended ceiling system comprising a grid of profiles for supporting the ceiling tile, the ceiling tile comprises a front surface intended to face a room in an installed state of the ceiling tile and a plurality of spacer elements discretely distributed along a perimeter portion of the ceiling tile. The plurality of spacer elements is formed separately from the ceiling tile, wherein each spacer element comprises a body portion and an anchoring portion for attaching the body portion to the ceiling tile.
