The louvre is 100% glare-free, with a design based on the principle of a reflective three-shade system, which directs most of the light downwards. For some variants, the top shade is made of deep drawn aluminum with white inner surface that ensures gentle, downward light distribution. The two bottom handblown opal glass shades ensure a large glare-free light surface, making optimum use of the light source to provide comfortable, functional lighting. The PH 3½-2½ Glass Table lamp was designed in 1928 and is one of many advanced projects undertaken by Poul Henningsen in the development of his world-famous three-shade system from 1926. Poul Henningsen devoted most of his life to taming electric light. He based his three-shade design on a logarithmic spiral to make optimum use of the light source. He was constantly doing calculations and tests. The form of the shades was determined by the way they were required to shape and reflect the light, and the lamp was designed to be glare-free.

Stunning original production PH-table lamp model "3,5/2" by Poul Henningsen manufactured at Louis Poulsen, Copenhagen in the 1940s. The lamp base is made from patinated brass and white bakelite parts. The shades are all original and unrestored. The upper shade is made from yellow lacquered metal with a wonderful patina while the middle and lower are made from frosted matte glass which gives a wonderful light distribution. A beautiful and rare example of the world famous lamp icon. Poul Henningsen designed the three-shade system back in 1925-1926. The first lights using the system were designed by PH in cooperation with Louis Poulsen for an exhibition in Paris. PH sought to create glare-free light, direct light where it was most needed, and create soft shadows, using incandescent bulbs as a light source. PH 3/2 Table is a member of the three-shade family. Thus PH did not just design a light, but an entire system – around a thousand different models have been produced over the years. 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, made it possible to control glare and shadow. Each shade reduces the amount of light equally, due to their distance from the light source. The PH light model numbers refer to the shade size. Each top shade had a corresponding set of middle and lower shades. In the ‘pure’ models, such as the 2/2, the top shade has a size of about 20 cm, with corresponding lower shades. PH 3/2 Table consists of an app. 30 cm top shade, but uses lower shades from the 2/2 model. These ‘hybrid’ models were introduced due to the desire to hang the pendants at lower heights. The system was also used for wall, table and floor lamps. This specific example has a "3,5" top shade (33,7 cm.) and a "2" middle and lower shade making it a "3,5/2 PH lamp".

The fixture is designed based on the principle of a reflective three-shade system, which directs the majority of the light downwards. The shades are made of handblown opal three-layer glass, which is glossy on top and sandblasted matte on the underside, giving a soft and diffuse light distribution.
