When it comes to lighting design, few brands are as iconic as Louis Poulsen. Established in 1874, the Danish company has been at the forefront of lighting innovation for over a century, producing some of the most enduring and timeless designs in the industry. Arguably its most famous range is the PH series, which includes the PH 5, PH 4, PH 3½-3, PH 3½-2½, PH 3½-2 and PH 3½-1½ – all of which were designed by the legendary designer Poul Henningsen. This article will focus on the PH 5, PH 4, PH 1 and PH 2 models, exploring their enduring appeal and the role they have played in shaping lighting design.

The PH Series: A Brief History

The PH series was designed by Poul Henningsen (1894-1967), a Danish designer whose work shaped the course of modern lighting design. Henningsen was obsessed with light and believed that his mission was to ‘tame’ it. His designs are characterised by their meticulous attention to detail and their focus on harmonising form and function. He is credited with inventing the concept of the ‘multiple shade’ lamp, in which several layers of shades are used to diffuse light and eliminate glare. The PH series was Henningsen’s most ambitious project, and it remains one of the most recognisable and beloved lighting ranges in the world.

The Design: Form Meets Function

One of the reasons why the PH series has endured for so long is its impeccable design. The PH 5, PH 4, PH 1 and PH 2 models are all characterised by their elegant, minimalist forms and their clever use of multiple shades. Each model is designed to cast a soft, diffused light that is easy on the eyes and creates a warm, inviting atmosphere. The PH 5, for example, features three nested shades, each with its own ring of holes that diffuses light in different directions. This creates a soft, warm glow that is perfect for a living room or bedroom. The PH 4, on the other hand, features four nested shades, each with a slightly different shape and size. The result is a lamp that casts a soft, even light that is ideal for a dining room or workspace. The PH 1 and PH 2 are smaller models that were designed for smaller spaces, such as hallways or entryways. Despite their smaller size, they still feature multiple shades and cast a warm, inviting light.

The Materials: Craftsmanship and Quality

In addition to their impeccable design, the PH series lamps are also known for their high-quality materials and craftsmanship. Louis Poulsen uses only the finest materials, including brass, steel and glass, to create lamps that are not only beautiful but also durable and long-lasting. Each lamp is meticulously crafted by skilled craftsmen who take pride in their work and are committed to producing lamps that will stand the test of time.

The Enduring Appeal: Modern Design Classics

Nearly a century after their initial release, the PH series lamps remain as popular as ever. Their clean lines, elegant forms and soft, inviting light have earned them a place in design history as modern classics. They have been used in countless homes, offices, restaurants and hotels around the world, and have become synonymous with good taste, style and quality. What’s more, they have inspired countless imitations and knockoffs, but none have been able to match their unique blend of form and function.

The Louis Poulsen PH series is a testament to the enduring appeal of good design. By combining form and function in a way that is both elegant and practical, Poul Henningsen created lamps that are as relevant today as they were when they were first designed. Their enduring popularity is a testament to their quality, craftsmanship and beauty, and their place in design history is assured. Whether you’re looking to add a touch of elegance to your home or workspace, the PH series is a great choice – a perfect combination of form and function.
