Abstract

Es wird eine Lamellenanordnung für Leuchten zur Abblendung und Lenkung von Licht, das von mindestens einer Lichtquelle (3) abgestrahlt wird, mit mehreren an einer Halterung befestigten Lamellen (2) vorgeschlagen. Die Lamellen (2) sind als transparente Prismenkörper (21) ausgebildet, wobei im Querschnitt eines Prismenkörpers gesehen der Abstand der Seitenflächen zueinander zur Lichtquelle (3) hin abnimmt.
