Abstract

La présente invention réduit de manière spectaculaire une consommation d'énergie tout en conservant les performances d'un éclairage d'entrée dans un tunnel à l'aide d'un éclairage artificiel pour l'éclairage d'entrée. Un système d'éclairage d'entrée de tunnel (20A) est configuré à partir : d'une structure de préacclimatation (12A) qui est disposée sur le côté avant de l'embouchure (10a) d'un tunnel (10), comprend une pluralité de panneaux de cellule solaire (21), génère une lumière indirecte (902) à partir d'une lumière naturelle (901) au moyen de l'espace de modulation de lumière (21a) de chaque panneau de cellule solaire (21), et constitue un segment de préacclimatation (LA) pour commander la distribution de luminance de la surface de route qui diminue progressivement dans la direction vers l'embouchure (10a) sur la route (11) ; et une pluralité de luminaires (22) qui sont disposés dans l'intérieur du tunnel (10) au voisinage de l'embouchure (10a) et qui éclairent au moyen d'une alimentation fournie à partir des panneaux de cellule solaire (21) par l'intermédiaire d'un câble (23). Différentes résistances de charge (RW) sont disposées sur les câbles de raccordement respectifs (23a) pour connecter chacun des luminaires (22) avec le câble (23) de sorte que la distribution de luminance de la surface de route diminue progressivement dans la direction d'avancement du tunnel (10) à partir de l'embouchure (10a).
