Poul Henningsen designed the triple shadow system in 1925-1926. The first lights using the system were designed by PH in collaboration with Louis Poulsen for an exhibition in Paris. PH designed not just a light, but a whole system, and over the years around a thousand different models were produced. PH was the first to take a scientific approach to light, based on the logarithmic spiral. By using a design based on the logarithmic spiral, he achieved an even distribution of light along the entire curve of the shadow. This even distribution of light, together with the diffuse reflection from the glass, made it possible to control glare and shadow. PH light model numbers refer to the shade size. The PH 4½-3½ Glass Floor consists of a top shade of approximately 45 cm, but lower shades were used than the 3½ model. The lighting was introduced in its current form in 1990.
