The AJ Royal pendant provides ambient illumination for all kinds of spaces. The lamp’s integrated LED light source together with an opal diffusor ensure an even and glare-free downward light while the open rings at the top allow the light to be filtered upwards, creating a muted, smooth lighting in any room, be it above a dining table or in a restaurant, office or showroom. The lamp is also known as AJ Pendant, and it is one of the many designs created by Danish architect Arne Jacobsen for the SAS Royal Hotel in Copenhagen which opened in 1960. Jacobsen was in charge of designing the hotel in its entirety, including the decor, furniture and lighting. Since then, the AJ range has become a Danish design icon and one of the most beloved pieces created by Arne Jacobsen.

Arne Jacobsen

Arne Jacobsen (1902-1971) is the most celebrated post-war Danish designer and architect. He graduated from the School of Applied Arts in 1924 and from the Royal Danish Academy of Fine Arts, where he studied architecture, in 1927. Arne Jacobsen worked actively both as an architect and as a designer and received many prestigious awards for his designs, including C. F. Hansen Medal and the Grand Prix of Milan XI Triennale.

Jacobsen’s most famous project was the Royal Hotel in Copenhagen (1956-1960), for which he designed every detail from textiles and lamps to cutlery and furniture. The AJ lamps, designed for the Royal Hotel and manufactured by Louis Poulsen, are a fine example of his streamlined and elegant style. The cutlery designed for the Royal Hotel and produced by Georg Jensen, represents a stylish design that is still today much praised. Also, the famous Egg and Swan chairs were designed for the Royal Hotel. As often happened with Arne Jacobsen’s designs, they were initially realized for a certain project and only later put into serial production – the same happened for the AJ lamps, the cutlery and the furniture he designed for the hotel. Royal Hotel was an extremely important project for Jacobsen because he could finally put his theories of integrated design and architecture into practice.

Jacobsen is well-known also for the Cylinda Line range, designed for Stelton in 1967. Since the very beginning, Cylinda Line has been an undisputed icon of Scandinavian design and today the range is part of numerous permanent collections in design museums all over the world.
