Abstract: A fixture having a cylindrical body, said body having an internal cavity extending from a first end to a second end, and said body having an exterior threaded portion, a flange affixed to the first end of the body, a portion of said flange extending past the circumference of the cylindrical body, said flange formed for receiving an electrical component, and a fastener complementary to the threaded portion, wherein the fastener and the flange are operable to secure the cylindrical body to a structure. An electrical component such as a luminaire, a switch or an electrical receptacle may be mounted into the flange portion of the fixture. A retainer may also be employed to distribute the load on the cylindrical body when positioned over the body and secured by the fastener.

Abstract: A device comprising a chassis, which may be formed with a strut and a hollow housing, the chassis having a groove disposed at an end for receiving a cross member such that the cross member is slidable within the groove. Some embodiments may have a plurality of suspension wires, said suspension wires coupled to the cross member to provide support for the fixture. Some embodiments may have rotatable hubs connected to the cross member, the hub for providing support for a light source attached to the hub. Some embodiments may provide for a ballast disposed into the housing.

Abstract: A device comprising a solid state or mechanical switch coupled to a first connector and a second connector and at least one lighting device such as an LED light source wherein when power is applied to the first connector, the switch is operable to direct power to the lighting device and to a portion of the pins of the second connector. By constructing the connectors as similar, but with opposite genders, the connectors can be disposed on a circuit assembly to allow for daisy chaining a series of luminaire assemblies together. The connectors may be Ethernet connectors and the switch may be operable through control signals coupled to the Ethernet connector such that a smart power controller operating using power over Ethernet (POE) can operate to control the light sources.

Abstract: A fixture holder comprising a plate having one or more mounting holes; a base support having a threaded through hole, said base support affixed to a first side of the plate by a threaded ferrule, said ferrule passing through the plate and being affixed to the plate by a fastener on a second side of the plate; said base support having one or more armatures extending perpendicular to the plate and proximately located peripherally about the threaded through hole such that the threaded through hole is not obstructed; and a conduit connector affixed to the threaded ferrule, for providing a connection to an electrical conduit, wherein said armature has at least one female threaded hole disposed thereon and the plate, base support and conduit connector form a lumen through the fixture holder.
