PH 4/3 Table Lamp


Poul Henningsen designed the three-shade system in 1925-1926, initially collaborating with Louis Poulsen for a Paris exhibition. This partnership lasted until Henningsen's death in 1967. He aimed to create glare-free light, direct it where needed, and produce soft shadows using incandescent bulbs.

Henningsen's three-shade system included table, floor, and wall lamps, as well as chandeliers. The lights came in various colors and sizes, with early shades made of metal and later ones of glass. Glass shades provided both downward and ambient room illumination.

Henningsen's scientific approach to lighting used the logarithmic spiral for even light distribution and glare control. Each shade reduced light equally based on its distance from the source. The PH light model numbers indicated shade sizes, with 'pure' models featuring matching top and lower shades. Hybrid models, like the PH 4/3 Table introduced in 1966, used different shade combinations to allow for lower pendant heights.

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.


Established in 1874 as a lighting manufacturer, Louis Poulsen has become one of the world's leading producers of lighting. This success is attributed to collaborations with renowned designers and architects like Arne Jacobsen, Øivind Slaatto, Poul Henningsen, and Verner Panton.
