The table lamp design is the result of craftsmanship. digital and its initial concept is the Joahannes Sebastian Bach “Prelude for Lute song”. Prelude is an introductory piece to a larger work, such as an opera, for example. The creation process takes place in 3 steps: the first is the modeling of the Lute, with the realistic creation of the components, musical instrument materials and colors in the Rhinoceros® software; the second is the deconstruction of the shape, slicing the volume into the three Cartesian planes and the selection of emphatic pieces, rosette of the soundhole, neck, strings, bridge and soundboard; the last step is the digital fabrication in laser cutting and the mounting the luminaire. In this way, the luminaire is structured in two verticals parte and locked by horizontal pieces repeated in the cadence of the frets of the instrument arm, resting on the bracket that houses transformers and power supply. Thus, the prelude announces Fac si Lux.
