For more than 70 years, Louis Poulsen has collaborated with visionary architects and designers producing innovative lighting solutions for buildings internally and externally. In the 1920's their first collaboration (and by no means their last) was with designer Poul Henningsen for the international exhibition for decorative Arts in Paris.  Henningsen won with his multi shade lamp which later became known as the PH Lamp, this lead to a contract to provide lighting for the Forum building in Copenhagen.

There started a perfect partnership: a designer who was the first expert in Light theory, and a lighting manufacturing company at the forefront of lighting technology and materials. In 1958 Henningsen designed the PH Artichoke lighting for the Langeline Pavilion in Copenhagen.

The idea behind such a functional piece of art was to create a glowing atmosphere but still look decorative, the original lights still hang there today. The Artichoke is a 360 degree glare-free luminaire created by 72 leaves that shield the light source, giving a distinct, unique illumination. Considered to be a classical masterpiece the Artichoke celebrates its 50th birthday this year, a great design that can stand the test of time, and will most certainly be around for a good while yet!
