This collaboration lasted until P. Henningsen's death in 1967. During his lifetime, Poul Henningsen wished to create light fixtures emitting a glare-free light which project soft shadows and guide the light cone to the right spot. The model PH 4/3 is one of the models of the series comprising 30 models with three-part shade. Poul Henningsen's concern was not only to create a light fixture, but a whole system, now comprising about thousand models. The large range includes table, floor and wall lamps and many chandeliers that became more and more popular as suspended interior illumination during the 1930s. There was many possibilities of combination, because the light fixtures were available in various sizes and colours. The first models made of metal had lacquered inner sides in white, gold or silver colours, should the light seem diffuse, warm or cold. Later, the three-part shades were made of glass, so that the light shone not only downwards but also into the room. Poul Henningsen was the first to deal with light on a scientific level and, for this purpose, used a logarithmical spiral. With its aid and the use of glass he achieved an even light distribution and a diffuse reflection, i. e. glare and shadow effects could be influenced at will. Because of the individual shade elements, the lightness is evenly subdued. The numbers designating the models refer to the size of the shade segments. The original light fixtures, as for example the model 2/2 have three segments with a diameter of 20 cm each. The model PH 4/3 is composed of an upper segment with a diamter of 40 cm and two smaller ones below, coming from the model 3/3. They were designed because of the wish to have lower hanging suspensions. This model series also comprises wall, table and floor lamps. The model PH 4/3 in its present form was launched in 1966 on the market.
