Abstract

Die Erfindung betrifft einen rotationssymmetrischen Reflektor, dessen Reflektionsfläche aus mehreren Segmenten besteht, die in Umfangsrichtung der Reflektorachse mehrere in Radialrichtung aneinander anschließende Segmentreihen bilden. Die Segmente sind jeweils mit einem bestimmten Winkel im Kreis verteilt und in Längsrichtung der Reflektorachse mit verschiedenen Längen und Winkeln angeordnet, wobei die Form jedes Segmentes einem sphärischen Trapez entspricht. Das Gesamtleuchtfeld des Reflektors besteht aus mehreren vollkommen kreisförmigen, einander überlagerten Leuchtfeldern, die durch die Segmentreihen in Umfangsrichtung der Reflektorachse erzeugt werden.

The invention relates to a rotationally symmetrical reflector, the reflection surface of which consists of a plurality of segments, which form in the circumferential direction of the reflector axis a plurality of radially adjacent row rows. The segments are each distributed at a certain angle in the circle and arranged in the longitudinal direction of the reflector axis with different lengths and angles, wherein the shape of each segment corresponds to a spherical trapezoid. The total field of the reflector consists of several perfectly circular, superimposed fields of light, which are generated by the rows of segments in the circumferential direction of the reflector axis.
