Story
A cordless System PH lamp
Poul Henningsen sought glare-free light, direct light where it was most needed and soft shadows from incandescent bulbs. His mathematical approach, based on the logarithmic spiral, led to System PH in 1926, which over the years has grown to hundreds of models from floor lamps to table lamps, pendants, chandeliers and wall lamps.
The whole-sized shade set
The PH 1/1 is the smallest shade set of the system. Its top shade of approximately 10 cm corresponds to the middle and lower shade in the proportions 3:2:1.
