Here is a short description from Fenhann's website:
Lamps in Oregon pine
The minimalist design comes from geometry. Rasmus Fenhann is using the old polyhedral shapes in a new way.
The 6 lamps are made by equilateral polygons, which make the lamps simple, poetic and functional: the light is allowed to spread to all sides, and the handmade paper gives a soft and pleasant light.
