Abstract

In verkehrstechnischen Signalisierungseinrichtungen werden Leuchtdioden (3,16) eingesetzt, um unterschiedliche Anzeigen darzustellen. Bisher ist keine Signalisierungseinrichtung bekannt, bei der eine ausreichende Wärmeableitung während des Betriebs sichergestellt ist.
Die Leuchtdioden (3,16) sind in einer rohrförmige Haltevorrichtung (4) mit ihren Seitenflächen so befestigt, daß eine gute Wärmeableitung von den Leuchtdioden (3) zur Haltevorrichtung (4) gewährleistet ist. Die Haltevorrichtung (4) ist fest, vorzugsweise lösbar, in einer Frontplatte (1) der Signalisierungseinrichtung befestigt. Zusätzlich ist eine optische Abbildungsvorrichtung (14) vorgesehen, um eine für Verkehrsteilnehmer optimierte Abstrahlungscharakteristik zu erzielen.
