Poul Henningsen PH piano lamp, 1930s Patented

Poul Henningsen PH 1/1 Piano Lamp, Louis Poulsen, Denmark, 1930s

A rare and elegant PH 1/1 piano lamp designed by Poul Henningsen, produced by Louis Poulsen, Denmark, circa 1930s.

This refined and functional lamp features a slender, curved brass arm mounted on a lacquered metal base, combined with the classic PH 1/1 shade system. The lamp is designed to provide focused, glare-free illumination, making it particularly suited for use on a piano, desk, or reading surface.

The combination of materials and proportions reflects Henningsen’s early exploration of directed light and ergonomic function, while maintaining the soft diffusion characteristic of the PH system. The compact scale and adjustable form add to its versatility and sculptural appeal.

Early PH piano lamps produced by Louis Poulsen are increasingly rare and highly sought after, particularly examples retaining their original components and patinated surfaces.
