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, a housing, a swivel ball device and a swivel ball controller. The swivel unit further comprises 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. The predetermined lamp-holding force retains the swivel ball device at any selected position while allowing easy manual movement of the swivel ball device. By a combination of rotations about the first and second axes, the apparatus can direct light to any objective oriented hemispherically with regard to the two axes while maintaining environmental integrity.
