PH 4-3 Table Lamp by Louis Poulsen

Poul Henningsen drew the models for his first PH lamps in collaboration with Louis Poulsen in 1924, where he developed the famous three-shade system. He was not primarily driven by the wish of designing aesthetic lamps, but instead to create the optimal light, to create a lampshade that emitted a functional, pleasant, and glare-free light. His work with Louis Poulsen continued until his death in 1967 and throughout his life, PH sought to create glare-free lighting, aiming to direct light where it was most needed and creating soft shadows while using incandescent bulbs as a light source.  PH 4-3 Table Lamp is a member of the three-shade family and was introduced in 1966.  PH was the first person to pursue a scientific approach to light and use the logarithmic spiral as a basis. By using a design based on the logarithmic spiral, he achieved even distribution of light over the entire curve of the shade. This even light distribution, together with the diffuse reflection through the glass,
