The Semi pendant lamp received an iF Design Award in 1971. It was designed by Thorup and Bonderup in 1969 while they were still students.

This Semi pendant lamp is a remake of the original. It is made in the 1990s when Horn Belysning bought Lyskær-Lyfa A/S, the company that was the owner of the ABO Randers and Fog & Morup brand.


Horn Belysning was founded in 1952 as a family business and first named E.S. Horn. In 1963 it changed into Horn BelysningHorn Lighting.

Horn Belysning produced lights for IKEA and several European retail chains. They designed lights but also imported lights from China. In the 1980s Horn Belysning was the second biggest light company in Denmark.

In 2005 the name changed into Lightyears, today owned by Republic of Fritz Hansen.

Fog & Mørup

Ansgar Fog (1880-1930) and Erik Mørup (1879-1972) started their business together in 1904 as a metalwork wholesaler. Two years later they moved to the capital Copenhagen and began to focus on lighting production and over the years taking over several electrical and lighting companies. It was only in the early 1960s that Fog & Mørup really emerged as a key force in lighting design, following the company’s appointment in 1957 of Jo Hammerborg as head of design.

Important designers and architects that worked for the company are: Claus Bonderup, Torsten Thorup, Sidse Werner. Sophus Frandsen, Jørgen Bo, E.  Balslev, Peter Avondoglio,. Karen Clemmensen, Ebbe Clemmensen, Hans Due and of course Jo Hammerborg himself.


In the late 1970s Fog & Mørup merged with Lyfa, another leading Danish lighting producer. In 1980 Jo Hammerborg retired. A few years later Lyfa-Fog & Mørup was taken over by Lyskær. The name changed to Lyskaer-Lyfa.

Lyskaer-Lyfa produced lights until 1991, when it was incorporated into Horn Belysning A/S from Aalstrup, also in Denmark, which was itself taken over in 2005 by Nordlux from Ålborg and at a large extent dismantled.

The original Semi lamp from the 1970s in a white version can be found here.


Also IKEA sold the Semi pendant lamp. It appears in catalogues from the 1980s. They did not change the name, as they often do with other lamps.
