Abstract: A lamp suitable for desk tops and the like includes a leg or upright resting on a base or other stationary element. An arm is secured to the leg and has a light source at its end. The arm and upright can be pivoted about various axes to allow the light source to be positioned arbitrarily to various positions. A support mechanism is provided inside the upright and the arm. The mechanism includes coil springs that are selectively compressed as the arm and upright are moved to generate supporting forces. The arm and upright does maintain their position and do not fall over after the light source has been positioned to the desired location.
