OSRAM Profile – from the OSRAM-website

Based in MunichGermany, OSRAM is a globally leading lighting manufacturer with a history dating back more than 100 years. The portfolio ranges from high-tech applications based on semiconductor technology, such as infrared or laser lighting, to smart and connected lighting solutions in buildings and cities.

OSRAM had more than 24,000 employees worldwide at the end of fiscal 2016 (September 30) and generated revenue of almost €3.8 billion in that fiscal year. The company is listed on the stock exchanges in Frankfurt and Munich.

In 1906 the OSRAM incandescent lamp was developed by Carl Auer von Welsbach.

In 1919 AEG (Allgemeine Elektrizitäts-Gesellschaft), Siemens & Halske (S & H) and Deutsche Gasglühlicht AG (Degea, German Gas Light Company) formed a company for incandescent lamp production under the name OSRAM.

The name is derived from osmium and wolfram, two elements that were commonly used for lighting filaments at the time the OSRAM-company was founded.
