ABSTRACT:
An adjustable photographic light stand includes a base supported on rolling casters, and a column extending upwardly therefrom. An extendable boom arm is joined to the column by an adjustable carriage assembly which maintains the boom at any elevation along the column. A handle stored within the boom arm is extendable to raise or lower the carriage assembly and the boom arm. An L-shaped gimbal arm member is rotatably joined to the distal end of the extendable boom. A yoke member is rotatably joined to the distal end of the gimbal arm member, and is adapted to support a lamp head, X-ray unit, or the like. The yoke member provides rotational adjustment of the lamp head about two orthogonal axes, while the gimbal arm member provides for revolving adjustment about a third axis. The extendable boom arm provides lateral positioning of the lamp head, and the adjustable carriage assembly enables height adjustment of the unit.
