Abstract

L'invention concerne un signal lumineux, en particulier pour des voies de communication ferroviaires, ledit signal lumineux présentant une source lumineuse (2) et un système optique (3) pour la visualisation d'une indication de signal dans une zone lointaine et une zone proche formant un certain angle par rapport à cette dernière. Pour réduire le feu fantôme sans perte importante de lumière, le système optique (3) présente un segment de fibre optique (8) destiné à dévier un flux lumineux partiel dans la zone proche.
