For 100 year, the name of OSRAM has been synonymous throughout the world with excellence in lighting. OSRAM was registered and protected as a brand name in 1906. In 1919, three manufacturers – Siemens & Halske AG, Deutsche Gasglühlicht Anstalt (Auer-Gesellschaft) and AEG – combined their lamp production operations. This was the birth of the successful company that is now OSRAM GmbH. We are now one of the two leading lighting manufacturers in the world.
