The head of this lamp by London designer Klemens Schillinger can rotate freely without the interruption of wires.
Schillinger's Lamp 11811 is lit by LEDs inside a disc, which can spin on an axis in a full circle thanks to a series of elements that pass electricity through the metal structure.
A conventional power cable runs up the long thin stem from the base, branching into positive and negative through bows on either side of the disc.
The electricity is then transmitted to the LEDs via slip rings made from small copper tubes, which have permanent contact with aluminium holes in the bows.
Bespoke 3D-printed nylon parts sit between the metal parts to secure them in place. Other components are laser-cut from standard tubes.
The anodised aluminium light is designed as table and floor versions. Photos are by Leonhard Hilzensauer.
