LIGHT-GUIDING ASSEMBLY AND AUTOMOTIVE VEHICLE ROOF

摘要

A light-guiding assembly for vehicle roofs has a plurality of glass sheets ( 1, 2 ) with an interlayer ( 3 ) of a polymeric laminating material interposed. The light-guiding assembly has light-coupling means ( 5 ) for coupling light into the light-guiding assembly. According to the invention, the light coupled into the interlayer ( 3 ) is substantially guided through the interlayer ( 3 ). Preferably, the refractive index of the interlayer is higher than the refractive index of the glass sheets. Preferably, refractive layers ( 8, 9 ) of a material with a refractive index lower than the refractive index of the interlayer ( 3 ) are provided adjacent the interlayer between the respective glass sheets ( 1, 2 ) and the interlayer ( 3 ). Preferably, the light-guiding assembly is provided with a recess ( 10 ), the recess ( 10 ) being adapted to receive the light-coupling means ( 5 ).
