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.

Figure 00000001
A slat arrangement for luminaires for dimming and directing light, which is emitted by at least one light source (3), with a plurality of slats (2) attached to a holder is proposed. The lamellae (2) are designed as transparent prism bodies (21), the distance of the side faces from one another to the light source (3) decreasing as seen in the cross section of a prism body.
