Designed by Simon Bruenner, Neues Licht’s Ufo is a pendant lamp that’s entirely optical - the light source is hidden away in the ceiling. The light flows through the tangle of the glass fibers to the edges where the “the Ufo radiates, marking the boundaries of the illuminated area and emphasizing the depth of the surrounding space.”. Also from Neues Licht, the all-optical Anemone and Scintilla chandelier, after the jump.
... the Ufo, Anemone and Scintilla's light source is hidden away.
To demonstrate the difference between optical and electrical, here's the Ufo lamp under water at Munich's Sealife aquarium.
