Abstract
Abstract A light support portion is interconnected to a first spring means. The first spring means is interconnected with a second spring means by an intermediate relatively rigid means which may include a swivel joint connected at an intermediate point thereof. The second spring means is interconnected with a mounting means which movably mounts the lighting fixture for movement with respect to a support means, the lighting fixture being supported in a generally horizontal relationship. The second spring means is shorter and more rigid than the first spring means and serves mainly to absorb vertical forces while the first spring means absorbs both vertical and horizontal forces.
