A display lighting system is provided that assembles and installs easily. Luminaires of the system include a pair of arms and a wireway enclosure positioned between the arms at one end of the arms. The enclosure is dimensioned to enclose electrical wiring and at least one electrical component, such as a ballast or transformer. A lamp housing can be attached to the arms at the end opposite the enclosure. An uplight lamp housing is easily mounted to the arms anywhere between the wireway enclosure and lamp housing. Wiring between the enclosure and lamp housings is carried inconspicuously in a trough along the inside of one or both arms. Wiring between adjacent luminaires runs conveniently through nipple connectors connecting adjacent enclosures. Optional accent lighting is also provided.

Cylindrical luminaire

A cylindrical luminaire is provided whose components align easily, for quicker assembly, despite the lack of intrinsic preferred relative orientation in circular components. Circular end plates affixed in a desired alignment to the end of an elongated reflector have notches for alignment of a part-cylindrical cover and slots or pivotal brackets to receive a baffle. The reflector, cover and baffle are accordingly assembled in proper alignment. The baffle can be an optical baffle to alter the aesthetic appearance of the luminaire.

A universal track light mounting system for mounting luminaires or other components to track lighting tracks of different sizes. The system includes a universal track clamp having first and second brackets that mount around the outside of a track. One bracket engages the top and one side of the track while the other engages the top and one other side of the track. A clamp fastener adjustably interconnects the brackets. A third bracket may be provided to anchor the clamp fastener to one of the first and second brackets. The adjustable interconnection enables the universal track clamp to mount to tracks of different sizes. To accommodate luminaires of different sizes, the clamp has several attachment positions, which also provide a coarse adjustment of the width of the clamp. Because luminaires are mounted to the track by a clamp around the outside of the track, a separate power adapter is provided to connect the luminaire to power conductors inside the track.

An adjustable elongated luminaire or elongated luminaire system, and a respective adjustable mount or mounting system therefor, that further minimizes dark spots in the lighting pattern, while allowing easy installation and adjustment, and providing a more effective braking mechanism, as compared to previously known systems, are provided. In a preferred embodiment, each luminaire has a hole at one end and a projecting stud at the other end. A mounting bracket for each end has a corresponding hole or stud. Where two adjacent luminaires meet in a luminaire system, the mounting bracket has a hole, and the stud of one luminaire extends through the hole in that mounting bracket as well as the hole in the adjacent luminaire. Brake mechanisms to lock one or more luminaires rotationally, and alignment mechanisms to lock multiple luminaires in a system into common alignment, can also be used.
