Product history
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. Over the course of his life, Poul Henningsen tried to achieve low-beam and direct lighting in essential areas, creating soft shadows with incandescent bulbs as a source. of light. The four-screen system was launched in 1931 to create a suspended lighting solution that could be used as an alternative to chandeliers. The four-screen PH lamp was designed to increase the amount of light scattered horizontally and illuminate walls and shelves to a greater extent than was possible with a standard three-screen 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.
