MUNICH, Germany and SAINT-QUENTIN, France - Osram purchased ADB TTV SAS, also known as ADB Lighting Technologies, on Aug. 3, and will run the company going forward as part of its Clay Paky lighting subsidiary. ADB, founded in Belgium in 1920, ran as a family business until 1987 when it was acquired by the Siemens Group. Under Siemens, it expanded from a maker of digital dimmers, memory control systems and condenser optics for theatre spotlights and emerged as a broadline manufacturer with facilities in Belgium and France,and a sales unit in Germany. Christian Léonard, then General Manager of ADB-TTV France, led a management buyout in late 2002. The company is now based in Saint-Quentin, with R&D, Product Engineering, Marketing and International Sales still located in Belgium.
