Pipes Lamp Pipes placed on top of each other to form a lamp. This simple - but nonetheless refined - concept underlies the design by Austrian designer Thomas Feichtner for the Italian lighting manufacturer Karboxx. Feichtner took bent pipe segments, all of differing lengths and with LEDs installed at both ends, and stacked them - each at a slight angle to its neighbors. The individual segments are two-dimensional lines that are fanned out to form a round, more unified body. In this way, simply adding the segments together gives rise to a geometric light object. This lamp was shown publically for the first time at the lighting exhibition (Euro Luce) of the 2015 Salone Internzionale del Mobile in Milan.
