Abstract

L'invention concerne un poteau de balise de type à émission de lumière spontanée qui peut conserver une visibilité nocturne sur une longue durée et qui peut être facilement constitué pour émettre la lumière d'un élément émettant de la lumière dans une direction désirée. Dans le poteau de balise, un organe émettant de la lumière (3) est équipé d'un élément émettant de la lumière (31), et cet élément émettant de la lumière (31) est disposé dans une partie de base (2), permettant ainsi de réduire la crainte que l'élément émettant de la lumière (31) soit cassé dans une collision ou autre accident similaire d'un véhicule. De plus, l'élément émettant de la lumière (3) est équipé d'une pluralité d'illuminants (31a et 31b). Il en résulte que, même si un illuminant (31) n'émet pas de lumière, un autre illuminant (31) peut conserver l'émission de lumière pendant la nuit de telle sorte que la visibilité nocturne peut être conservée sur une longue durée. De plus, il est facile de guider la lumière de l'élément émettant de la lumière (31) dans une direction désirée en fixant simplement l'élément émettant de la lumière (3) à la partie de base (2).
