Lampada PH 2/1

The luminaire was designed according to the principle of three reflective screens that direct most of the light downwards. The screens are made of three-layer blown opal glass, glossy at the top and opaque sandblasted at the bottom and offer a soft and even light distribution.

Product history
Poul Henningsen designed the three-screen system in 1925-1926. The first lights to use this system were designed by Poul Henningsen in collaboration with Louis Poulsen for an exhibition in Paris. This collaboration continued until his death in 1967. Over the course of his life, Poul Henningsen tried to achieve direct, low-beam lighting in essential areas, creating soft shadows with incandescent bulbs as a light source. PH 2/1 Sospensione is part of the 3-screen family which today includes 30 lamps, three of which are for outdoor use. Henningsen has therefore not only designed a lamp, but an entire system: around a thousand different models have been produced over the years. This large collection consisted of table, floor and wall lamps, as well as several chandeliers, very popular in the 1930s, to illuminate private homes with high ceilings. Numerous combination options were possible. The lamps were available in different colors and sizes. The first screens were made of metal, with the underlying surface painted in white, gold or silver, depending on the type of lighting desired: warm and enveloping or colder. Glass was later introduced into the three-screen system. In addition to directing the light downwards, the glass lamps illuminated the entire room. Henningsen was the first designer to pursue a scientific approach to lighting, using the lithium or logarithmic spiral as a base. Thanks to this type of design, Henningsen was able to achieve a uniform distribution of light over the entire curve of the screen. This uniform distribution, together with the diffuse reflection through the glass, enabled glare and shadows to be controlled. Each screen reduces the amount of light equally due to their distance from the light source. The PH lamp model numbers refer to the screen size. Each top screen has a respective middle and bottom screen. In "pure" models, such as the 2/2 model, the upper screen is approximately 20 cm wide, with corresponding lower screens. The PH 2/1 Sospensione consists of an upper screen of approximately 20 cm, but the lower screens are those used in the 1/1 model. These “hybrid” models were introduced to be able to hang the pendant lamps at lower heights.
