Le dispositif d'éclairage par DEL comprend quatre modules d'éclairage par DEL fixés à l'extrémité supérieure d'un poteau au moyen d'un système de montage, et un dispositif source de courant fixé à l'intérieur du poteau et conçu pour alimenter les modules d'éclairage en courant électrique. Chaque module d'éclairage comprend un substrat métallique rectangulaire placé au fond et au centre de celui-ci, sur lequel sont agencés une pluralité d'éléments DEL sous forme matricielle, et des plaques réfléchissant la lumière présentant une partie en gradin et inclinées par rapport à la périphérie du substrat de telle sorte que la surface délimitée par les plaques réfléchissant la lumière augmente dans la direction de projection de lumière. Les quatre modules d'éclairage par DEL forment deux paires occupant des positions adjacentes fixées à l'extrémité supérieure du poteau. Les extrémités arrière des modules d'éclairage par DEL de chaque paire sont opposées et fixées au poteau de manière à former un V.
