Story
Poul Henningsen's PH 2/1
Each PH lamp number refers to the size of its shades. The PH 2/1 Table has a top shade of approximately 20 cm, and its lower shades are the ones used in the 1/1 version.
Spiral shade design
The fixture is built on a reflecting multi-shade system for soft, harmonious and glare-free lighting. The shade design follows a logarithmic spiral, with the centre of the light source placed in the focal point of the spiral. The three-layer white opal glass directs the light primarily downwards.
