Abstract
This disclosure depicts a novel environmentally sealed and manually controlled swivel unit for use in an adjustable lighting fixture. The swivel unit comprises a base for establishing electrical and mechanical connection with a source of electrical power and is attached to a housing having a central housing bore. The swivel unit further comprises a swivel ball device having a spherical body and a tube extending from the spherical body with a means for sealing the swivel ball device within the housing. A lamp-holder is attached to the end of the tube. The swivel unit also comprises a minimum friction swivel ball controller and circular plate and a tension means for forcing the swivel ball controller against the swivel ball device, and, in turn, for forcing the swivel ball device against a shoulder of the housing. This defines a predetermined lamp-holding force. The swivel ball controller allows the swivel ball device to rotate about a first axis and also to rotate about a second axis perpendicular to the first axis. The swivel ball device and the shoulder on the housing form an environmentally sealed juncture.
