Procédé de commande d'une lampe extérieure, en particulier d'un réverbère, au moyen d'un dispositif de commande (6 ; 22a, 22b, 22c) affecté au réverbère, la lampe extérieure comprenant une entrée d'alimentation électrique, raccordée à une première ligne de phase (1 ; 24a, 24b, 24c) conduisant une tension du réseau et destinée à l'alimentation électrique de la lampe extérieure, et le dispositif de commande comportant une entrée de commande (10) raccordée à une deuxième ligne de phase (5 ; 26a, 26b, 26c),
    caractérisé en ce que le procédé comprend le fait que des signaux codés en longueur d'impulsion et codés en hauteur d'impulsion, qui sont définis avec plus de deux niveaux de tension, sont délivrés à l'entrée de commande (10) par le biais de la deuxième ligne de phase (5 ; 26a, 26b, 26c), lesquels signaux sont décodés par le dispositif de commande et utilisés pour la commande de la lampe extérieure, et en ce que le dispositif de commande (6 ; 22a, 22b, 22c) contrôle si les signaux codés en longueur d'impulsion et codés en hauteur d'impulsion contiennent un identifiant pour un programme de commande et, du moment qu'un tel identifiant est constaté, commande la lampe extérieure commandée par lui conformément au programme de commande correspondant à l'identifiant ou arrête le programme de commande correspondant à l'identifiant.
  2. Procédé selon la revendication 1, caractérisé en ce que la première ligne de phase (1 ; 24a, 24b, 24c) est raccordée galvaniquement à la deuxième ligne de phase (5 ; 26a, 26b, 26c).
  3. Procédé selon l'une des revendications 1 à 2, caractérisé en ce que le dispositif de commande (6 ; 22a, 22b, 22c) ignore des signaux codés en longueur d'impulsion et codés en hauteur d'impulsion reçus du moment que les signaux ne contiennent pas d'identifiant affecté au dispositif de commande et/ou à la lampe extérieure pilotée par le dispositif de commande.
  4. Procédé selon l'une des revendications 1 à 2, caractérisé en ce que le dispositif de commande (6 ; 22a, 22b, 22c) ne pilote un ou plusieurs composants électriques de la lampe extérieure qui lui est affectée, conformément aux signaux codés en longueur d'impulsion et codés en hauteur d'impulsion reçus, que si ce signal contient un identifiant qui est affecté au composant ou aux composants.
  5. Procédé selon l'une des revendications 1 à 4, caractérisé en ce que la lampe extérieure est commutée dans un état de fonctionnement ou mode de fonctionnement prédéterminé quand une durée prédéterminée, pendant laquelle une tension est présente de façon constante au niveau de l'entrée de commande du dispositif de commande ou pendant laquelle aucune tension n'est présente au niveau de ladite entrée de commande, est supérieure à une valeur limite prédéterminée.
  6. Procédé de commande de plusieurs lampes extérieures (20a, 20b, 20c), en particulier de plusieurs réverbères, au moyen d'un dispositif de commande (22a, 22b, 22c) affecté à la lampe extérieure respective, les lampes extérieures comportant respectivement une entrée d'alimentation électrique raccordée à une première ligne de phase (24a, 24b, 24c) pour l'alimentation électrique de la lampe extérieure, et le dispositif de commande comportant une entrée de commande raccordée à une deuxième ligne de phase, caractérisé en ce que les lampes extérieures individuelles sont commandées selon un procédé selon l'une des revendications 1 à 5, et les signaux codés en longueur d'impulsion et codés en hauteur d'impulsion délivrés à l'entrée de commande de la lampe extérieure respective sont identiques pour toutes les lampes extérieures.
  7. Lampe extérieure, en particulier réverbère, qui comporte une entrée pour une première ligne de phase (1 ; 24a, 24b, 24c), conduisant une tension du réseau, destinée à l'alimentation électrique de la lampe extérieure et un dispositif de commande (6 ; 22a, 22b, 22c), le dispositif de commande comportant une entrée de commande pour une deuxième ligne de phase (5 ; 26a, 26b, 26c), caractérisée en ce que le dispositif de commande (6 ; 22a, 22b, 22c) est agencé pour décoder des signaux codés en longueur d'impulsion et codés en hauteur d'impulsion qui sont définis avec plus de deux niveaux de tension et qui sont délivrés à l'entrée de commande (10), et pour les utiliser pour la commande de la lampe extérieure, et pour contrôler si les signaux codés en longueur d'impulsion et codés en hauteur d'impulsion contiennent un identifiant pour un programme de commande et pour, du moment qu'un tel identifiant est constaté, commander la lampe extérieure conformément au programme de commande correspondant à l'identifiant ou pour arrêter le programme de commande correspondant à l'identifiant.
  8. Lampe extérieure selon la revendication 7, caractérisée en ce que le dispositif de commande (6 ; 22a, 22b, 22c) est agencé pour constater si la valeur effective d'une tension reçue au niveau de l'entrée de commande correspond à un niveau de tension prédéterminé des signaux codés en longueur d'impulsion et codés en hauteur d'impulsion.
  9. Utilisation d'un système de lignes pour des lampes extérieures, en particulier des réverbères, une première ligne de phase (24a, 24b, 24c) conduisant une tension du réseau et une deuxième ligne de phase (26a, 26b, 26c) étant prévues pour chaque lampe extérieure, les premières lignes de phase (24a, 24b, 24c) étant respectivement raccordées à une première ligne collectrice de phase (1) pour l'acheminement de la tension d'alimentation, et les deuxièmes lignes de phase étant raccordées à une deuxième ligne collectrice de phase (5) de sorte que la délivrance d'une tension à la deuxième ligne collectrice de phase entraîne la délivrance d'une tension à chaque deuxième ligne collectrice de phase, les deuxièmes lignes de phase et la deuxième ligne collectrice de phase étant conçues de telle sorte que la délivrance de la tension du réseau à la deuxième ligne collectrice de phase permet de piloter un relais d'un ballast dans une lampe extérieure, caractérisée en ce que les lampes extérieures avec des signaux codés en longueur d'impulsion et codés en hauteur d'impulsion délivrés à la ligne collectrice de phase (5) sont commandées par un dispositif de commande (22a, 22b, 22c) respectif selon un procédé selon l'une des revendications 1 à 6 pour le décodage et le pilotage des lampes extérieures.
  10. Utilisation selon la revendication 9, un dispositif de commutation (11) étant prévu dans la deuxième ligne collectrice de phase (5) ou entre la deuxième ligne collectrice de phase (5) et une alimentation électrique, et les signaux codés en longueur d'impulsion et codés en hauteur d'impulsion pouvant être réglés sur les deuxièmes lignes de phase (26a, 26b, 26c) avec le dispositif de commutation (11) sur l'un des plusieurs niveaux de tension, le raccordement entre une alimentation en tension et les deuxièmes lignes de phase (26a, 26b, 26c) pouvant en particulier être interrompu par le dispositif de commutation (11).
