The PH 3/2 pendant lamp is a member of the PH3-shade product family. The PH3-shade system was initially a pendant lamp solution but fast became an example for other types of lamps such as table, floor and wall lamps as well as chandeliers. As a result of the different sizes, materials, surfaces and bulbs, more than a thousand variants have emerged over the years.
The PH 3/2 pendant lamp is a classic amongst the variants. It is based on the principle of a reflective multi-shade system with glare-free lighting. The shape of each shade leans on an logarithmic spiral that evenly decrease the amount of light emitted according to their distance from the bulb. This is how the 3/2 creates soft lighting.
The PH fixtures were designed as a rational lighting system where the size of the shade, its material, and its surfaces could be combined mutually according to the nature of the assignment. Each top shade size had a corresponding set of middle and bottom shades such that the proportions between the shades were roughly 3:2:1.
One of the basic models right from the beginning was a PH 5/5. The first digit in the fraction indicating the top shade’s approximate diameter, and the digit after the slash indicating that middle and bottom shades where “born” to this particular top shade. This means that the 5/5 had a top shade with a diameter of 50 cm, 31 cm diameter middle shade and a 16.5 cm bottom shade. This combination was good when the fixture was to be hung up high, but when the pendants were hung lower it was more suitable with a combination of a large top shade and smaller middle and bottom shades. This is how the PH 3/2 was born.
