  Optisches Signal. 



   Die Erfindung betrifft ein optisches Signal, bei welchem das Licht mittels Sammellinse scheinwerferartig in eine bestimmte Richtung geworfen wird. 



   In der Figur ist eine solche Sammellinse dargestellt, u. zw. ist hiebei eine Stufenlinse gewählt. 



   Neu sind hiebei die an der Oberfläche der Linse angeordneten Riffelungen, die so ausgebildet sind, dass eine Verbreiterung. des Lichtkegels nach einer Seite hin bewirkt wird. 



   Die Verwendung einer Linse gemäss der Erfindung ist besonders zweckmässig bei optisehen Signalen, die am Ende einer Kurve, eines Gefälles oder einer Steigung liegen, da durch die Verbreiterung des Lichtkegels nach einer Seite hin ermöglicht wird, das Lichtsignal nach verschiedenen Stellen der Strecke hin   mit gleicher Lichtintensität sichtbar   zu machen.

  Optical signal.



   The invention relates to an optical signal in which the light is projected like a spotlight in a certain direction by means of a converging lens.



   In the figure, such a collecting lens is shown, u. between a step lens is chosen.



   What is new are the corrugations on the surface of the lens, which are designed so that they are widened. of the light cone is caused to one side.



   The use of a lens according to the invention is particularly useful for optical signals that are at the end of a curve, a slope or an incline, since the widening of the light cone to one side enables the light signal to be the same to different parts of the route To make light intensity visible.
