Louis Poulsen

PH 4½-3 Outdoor Wall Lamp

The fixture is designed based on the principle of a reflective three-shade system, which directs the light downwards. The shades have a matte white painted inside to ensure diffuse, comfortable light distribution.

Poul Henningsen designed the three-shade system in 1925-1926, aiming to create glare-free lighting with soft shadows. This system, developed with Louis Poulsen, includes around 1,000 models of table, floor, wall, and chandelier lights, known for their even light distribution based on the logarithmic spiral. PH Wall, launched in 1966, is part of this family and features a 45 cm top shade with lower shades from the 3/3 model, offering a unique hybrid design for lower-hanging pendants.

Louis Poulsen was established in Copenhagen in 1874, and its story began with the introduction of fine wines to the Danish market. By 1892 its focus had shifted towards lighting, and in 1924 its collaboration with Poul Henningsen began, followed by Arne Jacobsen in 1960 and later Verner Panton. Its collection spans pendants and ceiling lamps, floor, table and wall lamps, and outdoor lighting.

Poul Henningsen (1894-1967) was a highly influential Danish designer, architect, writer, and cultural critic, renowned for his pioneering work in lighting design, which remains integral to Louis Poulsen’s heritage. Born in Copenhagen to writers Agnes Henningsen and Carl Ewald, Henningsen initially practiced functionalist architecture but became famous for his innovative lighting designs. During WWII, he briefly served as the head architect for Tivoli Gardens before fleeing to Sweden, where he joined a community of Danish artists.
