Illuminated sign for PH Lampen (Louis Poulsen brand name for Henningsen lamps)

The PH-lamp is a term for light fixtures designed by Danish designer and writer Poul Henningsen.[1] The term is sometimes used to refer to any lamp designed by Henningsen[2] or specially Henningsen's three-shade lamp series.[3] The lamps are produced by Louis Poulsen.

Henningsen's lamps are designed with multiple concentric shades to eliminate visual glare, only emitting reflected light, obscuring the light source.[4] Henningsen's sleek, spare lamp was awarded a gold medal at the 1925 International Exhibition of Modern Decorative and Industrial Arts.[5]
