Abstract

Die Erfindung betrifft ein Lichtsignal mit einem für eine Glühfadenanordnung konzipierten optischen System (3) zur Abstrahlung des Lichts in mindestens einen Raumwinkel, insbesondere zur Darstellung von Signalbegriffen bei schienengebundenen Verkehrswegen. Um LEDs (5) unter Beibehaltung des optischen Systems (3) verwenden zu können, ist vorgesehen, dass die Glühfadenanordnung durch eine LED-Anordnung mit glühfadenspezifischen Charakteristika, insbesondere hinsichtlich geometrischer Abmessungen, Lichtstromhöhe und Lichtstromverteilung, ersetzt ist.

The invention relates to a light signal with a designed for a filament assembly optical system (3) for emitting the light in at least one solid angle, in particular for the presentation of signal terms in rail-bound traffic routes. In order to be able to use LEDs (5) while maintaining the optical system (3), it is provided that the filament arrangement is replaced by an LED arrangement with characteristics specific to the filament, in particular with respect to geometric dimensions, luminous flux level and luminous flux distribution.
