About the design
PH 4½-4 is an absolutely stunning large top tier Danish design piece by the “Master of Light” himself – Poul Henningsen, for Louis Poulsen. If you want classic iconic Danish design lighting – you won’t come much closer than this!
Mouth-blown opal three-layer glass shades, glossy on the outside and sandblasted matte on the inside, carefully arranged on a chrome plated aluminum frame and secured in place by small screws. This is a masterpiece in every sense of the word!
Emitting the trademark PH glare-free light – soft and diffused – it has endless uses in the stylish modern home. A true beauty alight as well as idle.
The PH 4½-4 is designed based on the principle of the reflective three-shade system – invented by Poul Henningsen in 1925-1926. The first lights were made in metal with painted inside, the glass pendants were introduced at later state.
The model number refers to the shade size – each top shade had a corresponding set of middle and lower shades. The ‘pure’ models, such as 4-4 that features a top shade with a diameter of 40 cm (15.7″) with corresponding lower shade, while the PH 4½-4 features a top shade with a diameter of 45 cm (17.7″), but uses the lower shades from the 4-4 model.
These ‘hybrid’ models were introduced due to the desire to hang the pendants at lower heights. The 4½-4 Pendant in its current form was introduced in 1980, 13 years after the death of Poul Henningsen.
Though out his life it became a mission for Poul Henningsen (PH) to create and perfect “the glare-free light” – excluding sharp direct light emittance from the bulb, and directing the light to where it’s needed, and at the same time casting off soft shadows.
The principle behind being the reflecting multi-shade system, based on a logarithmic spiral, where the focal point of the light source is placed in the center of the spiral.
