Beschreibung
Zusammenfassung:	The present invention provides an adjustment mechanism by which a luminaire may be adjusted and secured along an arcuate path. The adjustment mechanism includes a mounting bracket, adjustment bolt, adjustment brace, which is attached to the optical housing of the luminaire, and a positioning means, such as an eyebolt. The adjustment bolt is threadably attached to the adjustment brace via a non-rotatable nut. The adjustment bolt, which is disposed through the positioning means, is turned in order to adjust the position of the luminaire. As the adjustment bolt turns, the non-rotatable nut, along with the adjustment brace and optical housing attached thereto, moves along the threaded shaft of the bolt. When the turning of the bolt has ceased, the non-rotatable nut, adjustment brace and optical housing are secured in position by the frictional engagement of the thread of the bolt and the thread of the nut.
