ABSTRACT:
A rotating bracket (10) having a sleeve (20) slidably engaged with a vertical post, am arm (22) attached to the sleeve, and an extension (24) rotatably mounted to the arm (22) to position a curing lamp (14) at a desired rotational orientation. A bearing plate (36) on the arm (22) cooperates with the bearing plate (46) on the extension (24) to facilitate smooth rotation. A helical compression spring (58) urges said bearing plates (36and 46) into contact to hold the extension (24) and the curing lamp (14) at a desired rotational orientation.
