LUMINOUS MULTILAYER GLASS IN VEHICLE ROOF, VEHICLE CONTAINING IT, AND METHOD OF OBTAINING Russian patent published in 2020 - IPC B32B17/10 B60Q3/208 B62D25/06 

FIELD: transport machine building.

SUBSTANCE: group of inventions relates to a luminous multilayer glass in a vehicle roof. Glazed multi-layer luminous roof of vehicle comprises first transparent glass sheet (1) with first and second main sides, forming outer glass sheet, second transparent glass sheet (1') with third and fourth main sides, forming inner glass sheet, transparent laminating film insert, inorganic electroluminescent diodes (4) and set of optical collimators (5). Laminating insert is provided with through (20a) or blind (20i) holes. Each diode is connected to one through hole or blind hole containing a diode. Each optical collimator is connected to one electroluminescent diode (4), which is located in the hole. Optical collimator comprises array of two-dimensional structures on output side (52) or prismatic system, containing first array of prismatic structures (5) and second array of prismatic structures (5').

EFFECT: higher strength and simplified manufacturing of vehicle roof without deterioration of optical properties.
