Abstract (en)
Prismatic lamellas (2) are formed from transparent material which is virtually parabolically convex or virtually cylindrically convex or triangular. On their upper edges pointing towards the light device (3) they run pointedly and on their under sides (6) are convex. The device on the undersides is concave and mirrored, straight, straight and mirrored, convex, convex and mirrored, prismatic in a longitudinal direction, or prismatic in a cross-direction. The prismatic lamellas are formed as hollow chamber extrusions with hollow chambers in inverted form, which have a radiation path similar to that of a customary parabolic mirror screen.
Abstract (de)
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. <IMAGE>
