Abstract
A segment(S) for a visual signaler is proposed, in which the inner side (3) of the lateral face (2) is shaped in such a way in relation to its surface that it has a fluting structure with a sequence of at least two notches (12) in each of the first and second illumination regions (AB1, AB1), wherein the sequence of troughs and peaks alternates along the line of curvature of the lateral face (2) while the troughs and/or peaks are arranged in a straight line parallel to the lateral face (2) and/or substantially perpendicular, preferably completely perpendicular to the line of curvature along the inner side (3) of the lateral face (2). For improved signaling, at least two of the notches (12) in one of the illumination regions (AB1, AB2) have geometrically different designs.

A segment for a visual signaler comprising:
- a diffuser for transmitting visible light and for homogenizing a light distribution in a volume bounded by the diffuser, the diffuser comprising a light-transmissive lateral face in the visible range made of an optical medium and enclosing a cylindrical or conical frustum-shaped volume,
- having a reference plane in which at least one visual signaling element is configured to emit light toward the optical medium, the reference plane extending in a perpendicular to a base of the cylindrical or conical frustum-shaped volume,
- wherein the perpendicular bisectors of the secants through the lateral face within the reference plane categorize a volume on at least one side of the reference plane into a first illumination region and a second illumination region,
- wherein an inner side of the lateral face is shaped in such a way in relation to a surface of the inner side that it has a fluting structure with a sequence of a plurality of notches in each of the first and second illumination regions, wherein the sequence of a plurality of notches comprises troughs and peaks that alternate along a line of curvature of the lateral face while at least one of the troughs or peaks is arranged in a straight line parallel to the lateral face and/or substantially perpendicular,
- wherein at least two notches, of the plurality of notches, in one of the illumination regions have geometrically different designs,
- wherein the inner side of the lateral face has a step structure with a sequence of at least two steps as notches, wherein each step, of the at least two steps, is delimited by at least two limbs that meet at an edge in each case, wherein the edges are arranged in a straight line parallel to the lateral face and/or substantially perpendicular, and
- wherein the steps in the respective illumination region are designed in such a way that from a first step to a second step the at least two limbs that delimit the first step and the second step in the corresponding illumination region become monotonically longer or shorter.
