Introduction
Poul Henningsen, a Danish architect and designer, is widely regarded as one of the most innovative lighting designers of the 20th century. One of his most iconic designs is the PH 3/4 lamp, which has become synonymous with modern lighting design. In this article, we’ll take an in-depth look at the history of the PH 3/4, its design and construction, and its enduring popularity today.
The Origin of the PH 3/4 Lamp
Poul Henningsen began experimenting with lighting design in the 1920s, during a time when electric lighting was just starting to gain popularity in Denmark. Henningsen was unsatisfied with the harsh, direct light of the electric bulb, and was inspired by the soft, diffused light of gas lamps. He began to experiment with creating his own lighting fixtures that could replicate this soft, warm glow.
The PH 3/4 lamp was first designed in 1928, and was part of the PH series of lamps that Henningsen worked on throughout his career. The PH stands for “Poul Henningsen”, and the numbers represent the diameter of the shade in centimeters.
The Design and Construction of the PH 3/4 Lamp
The PH 3/4 lamp consists of a shade made up of multiple layers of colored glass, which diffuses the light and creates a warm, ambient glow. The three-layered shade has a sandblasted interior to create a soft, diffuse light, while the exterior layer is made of clear glass to allow the light to shine through. The shade is held by a metal frame, which also acts as a reflector to direct the light downwards.
One of the key innovations of the PH 3/4 lamp is its use of a three-screw mount. This allows the lamp to be adjusted to different angles, which in turn allows the user to control the direction of the light. This feature was a departure from traditional lighting design, which often featured fixed light sources in static positions.
The Enduring Popularity of the PH 3/4 Lamp
Despite being designed almost a century ago, the PH 3/4 lamp remains a popular choice for many modern interiors. The lamp’s clean lines and simple, yet elegant design make it a versatile choice for a variety of settings.
In recent years, many companies have produced replica versions of the PH 3/4 lamp, which has helped to increase its popularity and accessibility. However, it’s important to note that authentic PH lamps are still produced by Louis Poulsen, the company that Henningsen worked with for most of his career. These lamps are made according to Henningsen’s original designs, and are considered by many to be the most authentic and high-quality versions available.
Conclusion
Poul Henningsen’s PH 3/4 lamp is an iconic piece of design that revolutionized modern lighting. Its soft, diffused light and adjustable design were a departure from traditional lighting, and helped to create a new aesthetic that is still popular today. Whether you’re looking to add a touch of vintage charm to your home, or you’re a fan of modernist design, the PH 3/4 lamp is a timeless choice that will never go out of style.
