In 1906 the austrian chemist Auer von Welsbach registered the name of "osram" at the German Imperial Patent Office. The name is taken from the names of the two metals: first osmium and later wolfram (the alternative name of tungsten). In 1919 Deutsche Gasglühlicht AG, Siemens-Halske and AEG agree to merge their lamp production facilities in Berlin and found OSRAM Werke GmbH KG.

In 1993 OSRAM acquires SYLVANIA North American Lighting, the second largest lamp manufacturer in North America.
