Abstract

L’invention concerne un guide de lumière flexible et transparent comprenant : une nappe de guidage de lumière flexible et transparente (601) adaptée pour guider la lumière par réflexion totale interne et pour permettre à la lumière de sortir par une face de sortie selon une première direction (x);au moins deux groupes d’éléments d’injection de lumière (602) adaptés pour coupler une nappe de guidage de lumière à au moins une source de lumière; etun élément (200) de support au pliage des éléments d’injection de lumière comprenant au moins deux séries d’éléments de pliage (203,204), chaque série étant associée à un groupe d’éléments d’injection de lumière différent; et lesdites au moins deux séries d’éléments de pliage (203, 204) étant décalées selon la première direction (x) de sorte que lesdits au moins deux groupes d’éléments d’injection de lumière (602) sont décalés selon la première direction (x).
