Title (EN) LIGHTING UNIT WITH LAMINATE STRUCTURE
(FR) UNITÉ D'ÉCLAIRAGE À STRUCTURE STRATIFIÉE
Abstract:
(EN) A lighting unit includes a glass laminate structure including a base layer formed from a first glass composition with a refractive index nbase and a surface layer fused to a surface of the base layer and formed from a second glass composition with a refractive index nsurface. The surface layer includes a high refractive index region with a refractive index nhigh and a low refractive index region with a refractive index nlow. nbase and nsurface satisfy the equation |nsurface - nbase | ≥ 0.001, nhigh is greater than or equal to nbase 1, and nlow is less than nbase. The high refractive index region is optically coupled to the base layer such that at least a portion of light propagating through the base layer leaks out of the base layer and into the high refractive index region. A display device or a luminaire can include the lighting unit.
(FR) L'invention concerne une unité d'éclairage comprenant une structure stratifiée de verre comprenant une couche de base formée à partir d'une première composition de verre, présentant un indice de réfraction nbase, et une couche de surface fusionnée avec une surface de la couche de base et formée à partir d'une deuxième composition de verre, présentant un indice de réfraction nsurface. La couche de surface comprend une région à indice de réfraction élevé présentant un indice de réfraction nélevé et une région à indice de réfraction bas présentant un indice de réfraction nbas. nbase et nsurface satisfont à l'équation [nsurface - nbase] ≥ 0,001, nélevé est supérieur ou égal à nbase et nbas est inférieur à nbase. La région à indice de réfraction élevé est couplée optiquement à la couche de base de telle sorte qu'au moins une partie de la lumière se propageant à travers la couche de base fuit de la couche de base et passe dans la région à indice de réfraction élevé. Un dispositif d'affichage ou un luminaire peut comprendre l'unité d'éclairage.
