This is Emilia Lucht and Arne Sebrantke of German design studio "We Love Eames", and they created a lamp that allows greenery to grow in windowless spaces.
"We think that plants are playing an increasingly significant role in our urban environment. The conditions for growing have always been the intensive care and plenty of natural light.
So we decided to design the mygdal plant light to greenery to grow in windowless spaces as hotels or restaurants. It doesn’t require any human care like ventilation or irrigation. The plant light makes use of the physical similarity between Led and sunlight. Thus, the plants can perform photosynthesis.
The luminaire is a completely self-sustaining ecosystem where the plants can grow undisturbed for years. The standing lamp provides a new type of electrically conductive glass coating (patent requested), which is able to stream the electricity invisible along the surface. There is no longer a cable connection between the power source and the Led necessary. This technical innovation opens up absolutely new opportunities in greenery design."
