Louis Poulsen Ph Artichoke Glass Chandelier 84 cm clear glass

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. 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. PH 2/1 Rigid suspension is part of the 3-shade family which today includes 30 lamps, three of which are for outdoors. Henningsen therefore not just designed a lamp, but an entire system: around a thousand different models were produced over the years. This large collection consisted of table, floor and wall lamps, as well as several chandeliers, very popular in the 1930s, for illuminating 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 white, gold or silver, depending on the type of lighting desired, warm and enveloping or cooler. Glass was later also introduced into the three-screen system. In addition to directing the light downward, the glass lamps illuminated the entire room. Henningsen was the first designer to pursue a scientific approach to lighting, using the lituum or logarithmic spiral as a basis. Thanks to this type of design, Henningsen managed to obtain a uniform distribution of light over the entire curve of the screen. This uniform distribution, together with the reflection diffused through the glass, allowed glare and shadows to be controlled. Each screen reduces the amount of light to the same extent due to their distance from the light source. PH lamp model numbers refer to screen size. Each upper screen has a respective intermediate and lower screen. In “pure” models, such as the 2/2 model, the upper screen is approximately 20cm wide, with corresponding lower screens. The PH 2/1 Rigid Suspension consists of three lights with an upper screen of approximately 20cm, but the lower screens are those used in the 1/1 model. These “hybrid” models were introduced to be able to hang pendant lamps at lower heights. The PH 2/1 Rigid Suspension in its current form was introduced in 2003.

Lighting system

The luminaire it 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, polished at the top and matt sandblasted at the bottom and offer a soft and uniform light distribution.
