A ceiling beam connector that permits the incorporation of ornamental panel designs such as triangles, parallelograms, and trapezoids into suspended ceilings. The connector has a faceplate attached to either two arms or a leg. The leg is attached to either the faceplate or an arm at an acute angle measured from an axis perpendicular to the faceplate. To maintain standard beam lengths and rout spacing at 2 foot, 3 foot, or 4 foot (61 cm, 91 cm, or 122 cm) beam spacing, the leg may project out at the following angles measured from the axis: about 14.0°, about 18.4°, about 26.6°, about 30.3°, about 45.0°, about 59.7°, about 63.4°, about 71.6°, or about 76.0°.

A hub for lighting at a grid intersection. The hub includes a light enclosure, light fixture, yoke, clip adapter, and beams. The enclosure includes connected walls each having a central offset portion with a connecting slot and multiple fixture slots. The yoke includes a middle section, two side sections, and two connector sections having protrusions. The yoke is attached to the enclosure by passing the connector sections through the connecting slots in opposite walls of the enclosure. Clips are inserted into the connecting slots that do not contain the yoke. The clips include arms extended therefrom and have protrusions. Beams with end adapters having holes are then connected to the enclosure by engaging the protrusions on the yoke and clips with the holes on the clip adapters. A light fixture can then be attached with fasteners passing through the fixture and slots in the fixture. Optionally a driver can be attached to the fixture.

A lighting fixture for a suspended ceiling including a grid of rails and hub forming an opening in the suspended ceiling has a housing with a mounting clip operable to toollessly mount to a vertical portion of a rail from above with a cam to resiliently expand the mounting clip laterally during mounting of the housing onto the rail, a light unit support connected to the housing and operable to toollessly mount to the hub, from above, and a light unit operable to toollessly mount to the light unit support, through the hub, from below the suspended ceiling.

An assembly for suspending ceiling panels, having a frame and suspension members for suspending the frame from a structure, the frame having intersection members and support members extending therebetween, each support member being for supporting a respective side of the ceiling panel, and wherein the ends of the support members are configured to engage with engageable portions provided circumferentially about each of the intersection members.

A grid mounting system for a suspended ceiling system in one embodiment includes a support structure and a mounting bracket coupled to the support structure. An elongated first grid member is pivotably coupled to the mounting bracket about a pivot axis defined by a pivot member. The first grid member is movable about the pivot axis in a plurality of angular mounting positions. In one embodiment, the grid mounting system further includes a second grid member which may be pivotably or fixedly coupled to the mounting bracket. The support structure may be a wall or perimeter trim bracket attached to the wall in some installations.
