EMI2.1
vorliegende Anordnung ist der Tripelspiegel so geschliffen, dass das zurückgestrahlte Licht etwas seitwärts von dem ausgestrahlten Licht wieder auf den Scheinwerfer trifft. Entsprechend den charakteristischen Eigenschaften des Tripelspiegels erscheint das zurückgestrahlte Licht in zwei Bündeln aufgeteilt, wovon das eine die Linse 10, das andere die Linse 11 trifft. Die Linsen leiten das Licht an die lichtempfindlichen Zellen 12 und 13 weiter, wobei es jedoch grundsätzlich genügen würde, nur eine davon zu benützen. Aus

zu sammeln. Die beschriebene Anordnung stellt nur ein Beispiel der zahlreichen möglichen Ausführungsformen der optischen Einrichtung dar.
PATENT-ANSPRÜCHE :
1. Zugschlussmelder, bei dem an der Strecke eine Lichtquelle und in deren unmittelbarer Umgebung eine oder mehrere lichtempfindliche Zellen so angebracht sind, dass sie von der Lichtquelle nicht unmittelbar bestrahlt werden, während sich am Zuge eine optische Vorrichtung befindet, die die von der Lichtquelle kommenden Strahlen auf die lichtempfindlichen Zellen zurückwirft, dadurch gekennzeichnet, dass diese Vorrichtung am Zuge als Raum-oder Tripelspiegel ausgebildet ist.

EMI2.1
In the present arrangement, the cube-corner mirror is ground in such a way that the light emitted back hits the headlight somewhat laterally from the emitted light. According to the characteristic properties of the triple mirror, the reflected light appears divided into two bundles, one of which hits the lens 10 and the other hits the lens 11. The lenses pass the light on to the light-sensitive cells 12 and 13, although it would be sufficient in principle to use only one of them. Out

to collect. The arrangement described represents only one example of the numerous possible embodiments of the optical device.
PATENT CLAIMS:
1. Train end indicator, in which a light source is attached to the route and in the immediate vicinity one or more light-sensitive cells are attached in such a way that they are not directly irradiated by the light source, while an optical device is located on the train that detects those coming from the light source Throws rays back onto the light-sensitive cells, characterized in that this device is designed as a spatial or triple mirror on the train.
