    The only name I know in the US is 'adjustable desk lamp'.

    Likely there is a term more specific within the lighting industry....

    yup..lots of related types here, for example,

    google it for more choices........

    Kind of a pantograph perhaps.

    I can add that the designer of the Luxo was the famous Norwegian Jac Jacobsen who developed this lamp in 1937.

    Ah where would we be without the good old balanced-arm lamp! Good work Jac.

    Sorry! I should have asked the question very differently. I should have asked for the name of the system that holds the lamp, or any similar system that can hold a certain weight. So if you know the name of the system please let me know.. thank you!

    This is a balance arm with a weighted base.

    You want the generic name of the mechanism, not just it's application in lamps. I suggest the mechanism in your photo might be called a "two parallelogram, two spring, equipoising mechanism".

    I got "two parallelogram, two spring" from here:

    http://en.wikipedia.org/wiki/Balanced-arm_lamp

    and "equipoising mechanism" from here:

    In the UK they all tend to be called "Anglepoise lanps", which is a brand name - similar to all vacuum cleaners being called hoovers. http://www.anglepoise.com/
