Poul Henningsen: designing the journey of light

A lamp can look beautiful when switched off and feel uncomfortable when switched on. Poul Henningsen addressed that gap between object and experience. The Danish Architecture Center traces his experiments with harsh electric light: collaboration with Louis Poulsen from 1924, a Paris presentation in 1925 and development of the three-shade system in 1926. The question concerned where light went, not simply what the lamp looked like. [1]

According to the manufacturer, the reflecting shades use geometry based on a logarithmic spiral. Their surfaces and distance from the source help distribute light and control shadows. Painted metal and glass produce different effects. There is no mysterious power in the silhouette: geometry works together with material. The commercial description documents the design principle, rather than providing independent measurements for every possible room and household arrangement. [2]

Another project makes that attention visible. Designmuseum Danmark describes the Artichoke lamp, called Koglen, designed in 1957 for Copenhagen’s Langelinie Pavillonen restaurant: 72 elements arranged in 12 rows shield the source. Those numbers belong to that particular design. They should not be transferred to the three-shade family, as though every Henningsen creation were an identical variation of the same object or used exactly the same construction. [3]

Try this editorial example. Draw a table from the side, a lamp and two people, one sitting and one standing. Trace a route towards the book, then towards each pair of eyes. We are not calculating a lighting installation or copying a Henningsen drawing. We are changing the question: beyond illuminating an object, what does its user actually see? The viewing position becomes part of the design problem. [2]

The exercise has a useful limit. A drawn arrow does not measure a room’s brightness, and an attractive photograph alone cannot establish a reader’s comfort. Our editorial lesson is to separate three judgments: the object’s profile, the behaviour of light and the person’s experience. We can consider them together without compressing them into one verdict, beautiful or ugly, delivered while looking through a shop window. [1]
