Twinelight / Lighting and lamps

Twinelight

This lamp supports large deformation from a straight strip shape to a rounded energy-saving bulb shape when pulled. Users can pull the strip like pulling the chain of a conventional lamp. The strip then starts to curl and light up.

Silicone with embedded liquid metal is fabricated as a pulling sensor, which is attached to the top of the lamp strip. Before the casting process, surface mounted LEDs are soldered on top of flexible copper strips. We then bond the copper strips with a paper substrate with angular cut patterns. The two layers, paper layer and air channel layer, are bonded together with half cured silicon.
