Other versions: The Poul Henningsen PH Hat wall lamp was produced in several colours and in two sizes, including a larger version. The smaller version, shown here, remains in production. Over the years, the lamp was manufactured in several variations and finishes. This example dates from the 1980s–1990s production period.

Henningsen designed this wall lamp specifically for bedroom lighting. For this reason, the inside of the shade was finished in pink, creating a soft and pleasant light. The lamp is generally known today as PH Hat, although the name P-hat also appears in older source material.

Poul Henningsen

Poul Henningsen was born on 9 September 1894 in Denmark, in the Copenhagen area. He studied at the Technical School at Frederiksberg from 1911 to 1914, and later at the Technical College in Copenhagen until 1917. Although he trained as an architect, he never graduated, and instead developed into a remarkably versatile designer, writer and cultural critic.

Throughout his life, Henningsen devoted himself to the study of light and its effect on everyday life. His work focused on creating lamps that produced comfortable, glare-free illumination through the careful control of light distribution, reflection and shielding. He is widely regarded as one of the great pioneers of modern lighting design.

His self-titled PH series became his most famous body of work. While large multi-shade pendants such as the PH Artichoke and the PH 5 are among his best-known designs, Poul Henningsen also created smaller and more playful lighting models, including the PH Hat wall lamp. Even in its compact form, the lamp reflects his central design principle: to shape the light in a soft and controlled way, while shielding the bulb from direct glare.

Henningsen was also a highly influential cultural figure in Denmark. During the 1920s he achieved his literary breakthrough, and he later became known for the politically engaged PH revues of 1929–1932. In addition to lighting, he also designed the celebrated PH Grand Piano in 1930, a radical and elegant reinterpretation of the traditional grand piano.

Before and during the Second World War, Henningsen was active as an anti-fascist voice. During the German occupation he eventually fled to Sweden, where he continued to support the resistance through coded and camouflaged writings. After the war he increasingly distanced himself from communist circles as his scepticism towards the Soviet Union grew. In 1963 he became a member of the Danish Academy. Poul Henningsen died on 31 January 1967.

Louis Poulsen

Louis Poulsen is a Danish lighting manufacturer with roots going back to 1874, when Ludvig R. Poulsen founded a business in Copenhagen. Originally a trading company, the firm gradually shifted towards electrical supplies and lighting as electricity became more widely used. In 1896 Ludvig’s nephew Louis Poulsen joined the company, and after Ludvig’s death in 1906 Louis continued the business. In 1914Sophus Kaastrup-Olsen became a partner, and the company name changed to Louis Poulsen & Co.

A decisive turning point came in 1924, when Poul Henningsen began his long collaboration with the company. His scientific approach to glare-free lighting and reflective multi-shade systems became central to the identity of Louis Poulsen and strongly influenced modern lighting design. Since then, the company has continued to combine functional light, architectural clarity and carefully considered form, following the idea that a lamp should not merely be an object, but a tool to shape light.

Over the decades, Louis Poulsen has produced both iconic domestic lighting and large-scale architectural lighting for public and professional spaces. The company remains one of the best-known names in Danish lighting design, with a strong emphasis on the quality, direction and atmosphere of light.
