Louis Poulsen PH 5-4½ & PH 6½-6 Pendant Light
PH 5-4½ & PH 6½-6 PENDANT LIGHT
PH 5-4½ & PH 6½-6 PENDANT LIGHT
Designed by Poul Henningsen
The trumpet-shaped top shade on the fixture provides illumination of the area above the three shades, which primarily direct the light downwards.
A base reflector and a blue glare ring protect against glare from all angles.
The strongest light is directly under the fixture. The shades have a matt white painted finish to ensure very comfortable lighting.
DESIGNER
POUL HENNINGSEN
Poul Henningsen was born in Copenhagen by the famous Danish writer Agnes Henningsen. He never graduated as an architect, but studied at The Technical School at Frederiksberg, Denmark from 1911-14, and then at Technical College in Copenhagen from 1914-17.
He started practicing traditional functionalistic architecture, but over the years his professional interests changed to focus mainly on lighting which is what he is most famous for.
Poul Henningsen designed the three-shade system back in 1925-1926. The first lights using the system were designed for an exhibition in Paris. His work with Louis Poulsen continued right up until his death in 1967.
Throughout his life, PH sought to create glare-free light, direct light where it was most needed, and create soft shadows, using incandescent bulbs as a light source.
The four-shade system was launched in 1931 to create a fixture which could be mounted high up and serve as an alternative to the commonly used chandeliers.
The PH four-shade light was designed to increase the amount of light emitted horizontally to provide greater illumination of walls and shelves than was possible using standard three-shade lights.
It was removed from the Louis Poulsen standard range in the 40s, but was redesigned in 1979 by two Danish architects – Sophus Frandsen and Ebbe Christensen – for the Charlottenborg exhibition building in Copenhagen, although in a larger size: PH 6½/6. To resolve the never ending glare problem, the two architects decided to add a small blue shade to the design.
They also added a new surface with a more matte, white painted shade, to achieve a more even, comfortable light – ideal for museums and exhibition rooms or as general lighting in rooms with high ceilings. A smaller version, the 5/4½, was created for the Aarhus Concert Hall in 1984.
