Abstract

L'invention concerne un dispositif d'éclairage qui est non seulement capable d'assurer l'éclairage d'une région relativement importante mais toutefois limitée et d'assurer une utilisation efficace de la lumière émise, mais qui possède également une structure simple et qui peut être fabriqué à coût réduit. L'invention concerne également un élément optique. Etant donné qu'il n'y a pas de surface réfléchissante dans la section X-Z, et lorsque l'on aligne la section X-Z avec le sens de la longueur d'une rue et la section Y-Z avec le sens de la largeur de la rue lors de l'installation du dispositif d'éclairage (10) sur un réverbère (SL), le dispositif d'éclairage peut éclairer la rue étroitement dans le sens de la largeur mais de façon large dans le sens de la longueur.
