Title (EN) TRAFFIC SIGNALS
(FR) FEUX DE SIGNALISATION
Abstract:
(EN) Traffic signal light, especially for a rail control system having an array of light emitting diodes (LEDs) (2). The intensity of light emitted by the LEDs (2) and/or the state of the LEDs (2) are monitored, and the result of this monitoring is used to control the array. This allows compensation to be made for a decrease in the intensity of light emitted by the LEDs (2) and for any failure of LEDs (2). Furthermore the results of the monitoring can be sent to a central control, for example a signal box, to display the state of a number of signals and allow the need for replacement to be determined.
(FR) L'invention concerne un feu de signalisation, destiné en particulier à un système de commande ferroviaire, ce feu étant pourvu d'un ensemble de diodes électroluminescentes (LED) (2). On contrôle l'intensité lumineuse émise par ces LED (2) et/ou l'état de ces LED (2), le résultat de ce contrôle étant utilisé pour commander l'ensemble desdites LED. On peut ainsi compenser la perte d'intensité lumineuse émises par les LED (2) et toute défaillance de ces LED (2). Les résultats du contrôle sont en outre transmis à une unité de commande centrale, par exemple un boîtier de signalisation, qui affiche l'état de plusieurs signaux et détermine les besoins de remplacement.
