  • the “light radiation” of the light source is not used directly, but via a combination mirror reflected in ring zones depending on the angle and in such a way that the reflected beams are refractively deflected by the prism rings of the stepped lens, so that a signal color that meets specifications is generated in the main beam region.
  • the different optical path length of the light rays through the prism rings has - in contrast to an optically transparent glass in the prior art - a considerable but calculable influence on the transmission.

Abstract

Dans des feux encastrés, il est essentiel que soient présents une lampe encastrée assurant le rayonnement de la lumière et au moins un prisme déflecteur permettant le rayonnement sous un angle prédéfini. Ce prisme déflecteur (9, 40) est constitué d'un verre coloré servant de verre de protection pour le feu encastré, la couleur de la lumière rayonnée correspondant à une nuance précise du diagramme de chromaticité. Un rayonnement unidirectionnel, bidirectionnel et/ou omnidirectionnel est possible. Une coloration appropriée du verre de protection (9, 40) permet d'obtenir les couleurs de signalisation exigées. Outre l'utilisation préférée comme feu encastré à rayonnement panoramique sur les terrains d'aviation, ces feux encastrés s'utilisent également sur les chaussées dans le réseau routier.
