About the design

PH 5-4 1/2 is a beautiful large top tier Danish design piece, made for high hanging. Originally designed by the “Master of Light” himself – Poul Henningsen, for Louis Poulsen.

The PH 5-4 1/2 pendant is a four screen lamp. Poul Henningsen (PH) designed the three-screen system as early as 1925-1926, when the first lamps were drawn for an exhibition in Paris. Throughout his life PH sought to create the perfect glare-free light – directing light where it is needed and casting soft shadows.

In 1931 the 4-screen system was launched, in order to create a fixture that could be mounted high up and thus provide an alternative to the frequently used chandeliers. The PH 4-shade lamp was designed to increase the amount of light emitted horizontally from the lamp, thereby providing more lighting on walls and shelves, than the ordinary 3-shade lights.

It was taken out of the Louis Poulsen standard productrange in the 40s, but was re-designed in 1979 by two Danish architects Sophus Frandsen and Ebbe Christensen for the exhibition building Charlottenborg in Copenhagen, in a larger size: PH 6 1/2-6. In 1984, the smaller version PH 5-4 1/2 was designed for the Concert Hall in Århus.
