An LED traffic signal is enhanced with a combination of a cylindrical opaque visor and a transparent cone that is placed over the lens. The visor is offset from the lens to provide a gap, an escape route for fast moving air that rushes down the cone and out the gap as described in the Bernoulli formula. Various embodiments include a wing shaped visor, a standard visor being cylindrical, and a custom visor being cylindrical.

    Un viseur cylindrique opaque et un cône transparent recouvrant la lentille viennent améliorer un feu de circulation à DEL. Le viseur est décalé par rapport à la lentille de manière à créer un espace qui sert de point de sortie pour lair qui circule rapidement le long du cône, comme lindique le théorème de Bernoulli. Diverses réalisations comprennent un viseur en forme daile, un viseur cylindrique standard et un viseur cylindrique fabriqué sur mesure.
