  • Description

    The PH 4½-3½ glass floor lamp is a member of the PH 3-shade family, and the principle behind the PH 3-shade fixture was made in the winter of 1925-26 for a large exhibition hall in Copenhagen, Denmark called "Forum". This is what PH said about his new fixture in 1926: "The real innovation in the PH-fixture is that it produces lighting which is both glare free and economical. It is easy enough to create glare-free light, indirect and strongly shaded, if a portion of the light is allowed to be wasted, and it is equally easy to make fixtures which are highly efficient if you ignore the fact that they severely irritate the eye, but it is an art to make light both economical and glare free." The first fixtures were all made with metal shades, but PH also wanted to develop a variant of the fixture, which would show a light distribution curve with less downward lighting. The result was shades made in opal glass with a sandblasted underside. The glass shades allowed 12% of the light to penetrate and contribute to the overall lighting of the room while most of the light was still reflected outward and downward from the matte undersides of the shades. The PH3-shade system started out as a pendant but very quickly it also developed into other kinds of fixtures for tables, floors, walls and a great number of chandeliers. As a result of using different sizes, materials, surfaces, colors and light sources, more than a thousand variants were developed over the years.

    Poul Henningsen

    The Danish left-wing writer, architect and designer Poul Henningsen (1894-1967) saw electric light as a way of enlightening the people by improving the home and work environment. After comprehensive studies into glare-free multi shade lamps, the electric appliances manufacturer Louis Poulsen enabled him to create the first PH lamp in 1926. The PH lamp was an instant success, sold and used all over the world including the Bauhaus Dessau building.

    After the outbreak of WW2 sales fell and by October 1943 Henningsen left German occupied Denmark for Stockholm together with Arne Jacobsen. On his return to Denmark in 1945 Henningsen continued to develop the multi shade lamp system and created many of his most beautiful designs, many still in production, including the highly popular PH5 from 1958. Henningsen left over 100 sketches of lamp designs behind after his death, some which have later been put into production by Louis Poulsen.
