ABSTRACT:
A stand-supported light source includes a combination of collapsing, telescopic and flexible joint couplings. For storage and shipping, a plurality of legs are collapsible to become longitudinally parallel to the longitudinal axis of the base. A telescopic arm coupled to the stand may also be pivoted into a longitudinally parallel axis and then telescopically retracted, which results in a very compact configuration. In use, the telescopic arm may be extended through a range of positions, and may pivot out of parallel with the stand base longitudinal axis, permitting the light source to be located through a wide and precisely controlled range of motion. The legs are pivoted and self locking at a limited range of motion, simplifying set-up. A special clamp accepts a standard trouble light, without inhibiting access to or use of the various electrical switches and outlets that might typically be found on the trouble light. Different embodiments detail the pivot, clamp and various combinations.
