ABSTRACT:
The present invention is directed to a new and improved design associated with the fabrication and construction of a lamp, the lamp comprising a first base member, a first supporting arm member, a second base member, a second supporting arm member, and an element housing member, the first supporting arm member having one end thereof being mechanically coupled to the base member by a mechanical coupling that allows for omnidirectional movement of the first supporting arm member about the vertical axis of the first base member while the second base member is mechanically coupled to the free end of the first supporting arm member by way of a mechanical coupling that allows for omnidirectional movement of the first supporting arm member in relation to the vertical axis of the second base member while maintaining as constant the orientation of the second base member as related to the first base member. A second supporting arm member is mechanically coupled to the second base member so as to allow for the omnidirectional movement of the second supporting arm member about the second base member. The free end of the second supporting arm member is mechanically coupled to the element housing member by a mechanical coupling that allows for the omnidirectional movement of the element housing member as desired.
