Poul Henningsen designed the three-screen system in 1925-1926. The first lights to use this system were made for an exhibition in Paris. His work with Louis Poulsen continued until his death in 1967. Throughout his life, Poul Henningsen sought to achieve glare-free, direct lighting in essential areas, creating soft shadows with incandescent bulbs as the light source. The four-shade system was launched in 1931 to create a suspended lighting solution that could be used as an alternative to chandeliers. The four-shade PH lamp was designed to increase the amount of horizontally diffused light and illuminate walls and shelves to a greater extent than was possible with a standard three-shade lamp. It was removed from Louis Poulsen's standard range in the 1940s, but was redesigned, albeit in larger dimensions, in 1979 by two Danish architects - Sophus Frandsen and Ebbe Christensen - for the Charlottenborg exhibition building in Copenhagen: PH 6½/ 6. To solve the glare problem once and for all, the two architects decided to add a small blue screen to the design. They also equipped it with a new surface with a screen with a more satin finish, painted in white, to obtain more uniform and comfortable lighting, ideal for museums and exhibition halls or as general lighting in rooms with very high ceilings. A smaller version, the 5/4½, was created for the Aarhus Concert Hall in 1984.

Designed to last

Designed to provide exceptional light, our lamps are made with high-quality materials to last a lifetime.

Lighting system

The funnel shape of the upper screen on the luminaire provides illumination of the area above the three screens which mainly direct the light downwards. The base reflector and a blue glare ring protect against glare from all angles. The strongest light is emitted directly under the luminaire. The screens have a matte white painted finish to ensure extremely comfortable lighting.
