CA 2380538

An LED signal module includes a casing defining a cavity. Within the cavity is an array of LEDs. Individual reflec- tors are placed around individual LEDs of the array. Also included, and covering the cavity, is a compound lens having individual fresnel lenses shaped to direct the output luminance of the LEDs below a horizontal axis of the module.

L'invention concerne un module signal à diodes électroluminescentes (DEL), comprenant un logement définissant une cavité. Cette cavité abrite une matrice de diodes électroluminescentes. Des réflecteurs séparés sont placés autour de chaque DEL de la matrice. De plus, le module comprend un objectif à plusieurs lentilles recouvrant la cavité ; cet objectif est pourvu de lentilles de Fresnel séparées, profilées de manière à diriger la luminance de sortie des DEL en dessous d'un axe horizontal du module.
