Title (EN) LIGHT GUIDE WITH PLURALITY OF LIGHT CHANNELS
(FR) GUIDE DE LUMIÈRE COMPRENANT UNE PLURALITÉ DE CANAUX DE LUMIÈRE
Abstract:
(EN) A light guide (100) comprising a light guide body plate (110) comprising a plurality of elongated light channels (120) extending substantially parallel to each other; the light guide comprising an out- coupling arrangement (140) for coupling light propagating in the light channels out of the light guide body plate through a first and/or a second main surface. In a horizontal transverse direction, each light channel (120) is confined between two confining stripes (130) formed of a solid confining material having a second refractive index lower than the first refractive index of the light guide body plate material, confining stripes between two adjacent light channels having a height less than the thickness of the light guide body plate.
(FR) L'invention concerne un guide de lumière (100) qui comprend une plaque de corps de guide de lumière (110) comportant une pluralité de canaux de lumière allongés (120) s'étendant sensiblement parallèlement les uns aux autres ; un agencement de couplage en sortie (140) permettant de coupler la lumière se propageant dans les canaux de lumière hors de la plaque de corps de guide de lumière à travers une première et/ou une seconde surface principale. Dans une direction transversale horizontale, chaque canal de lumière (120) est confiné entre deux bandes de confinement (130) formées d'un matériau de confinement solide présentant un second indice de réfraction inférieur au premier indice de réfraction du matériau de plaque de corps de guide de lumière, des bandes de confinement entre deux canaux de lumière adjacents présentant une hauteur inférieure à l'épaisseur de la plaque de corps de guide de lumière.
