Abstract

Die vorliegende Erfindung betrifft einen Zoom-Strahler mit variablem Strahlwinkel, umfassend zumindest eine Lichtquelle, eine Bündelungsoptik zum Abstrahlen eines Zoom-Strahlenbündels sowie ein Zoom-Element zum Einstellen des Strahlwinkels des von der Bündelungsoptik abgestrahlten Zoom-Strahlenbündels, wobei das Zoom-Element ein mit einer lichtstreuenden und/oder aufweitenden Streu- und/oder Aufweitstruktur versehenes, dünnwandiges Streu- und/oder Aufweitelement ist, das zwischen der Bündelungsoptik und der Lichtquelle vorgesehen ist, wobei das genannte Streu- und/oder Aufweitelement und/oder die Bündelungsoptik zum Einstellen des Strahlwinkels des abgestrahlten Zoom-Strahlenbündels hin- und herbewegbar gelagert ist/sind, wobei ein Wechselhalter zum Auswechseln des Streu- und/oder Aufweitelements und Einsetzen unterschiedlich ausgebildeter Streu- und/oder Aufweitelemente zum Erzeugen unterschiedlich konturierter und/oder unterschiedlich farbiger Strahlenbündel vorgesehen ist.
