This is the Construction Lamp and it was made by Joost van Bleiswijk. Looks almost like it was made from Meccano.

The four sided structure tapers with height, making it look like a telegraphy pylon. Available in both black or white, there's a floor lamp, and a second one short enough to be used on a table top. More information over at the links:
