Abstract

Bei einer Beleuchtungsanordnung (1), insbesondere in Form einer Stehleuchte (5), einer Tischleuchte oder einer abgependelten Arbeitsplatzleuchte zum Beleuchten eines Arbeitsplatzes (100), sind vorgesehen: Mittel zum Beleuchten eines Beleuchtungsbereichs (103), Mittel zum akustischen Erfassen eines in dem Beleuchtungsbereich (103) vorliegenden Schallsignals, Mittel zur Abgabe eines akustischen Gegen-Signals in den Beleuchtungsbereich (103), sowie eine Steuereinheit (9) zur Ansteuerung der Mittel zur Abgabe des akustischen Gegen-Signals derart, das durch das akustische Gegen-Signal innerhalb des Beleuchtungsbereichs (103) der Schall reduziert wird.
