The trend towards increasing the glazed area in automobiles has reduced the potential locations for mounting cabin lighting. This is especially true for vehicles having large panoramic glazing. Attempts to utilize integrated light sources within the glazing have had mixed results. Embedded LEDs in the laminate tend to be too bright for night driving. Edge feed illumination with light dispersing elements on the glass to date have only been able to provide low intensity levels. Both approaches tend to reduce visibility and aesthetics in the off state. The current invention provides a means and a method to produce a laminate which provides bright cabin lighting without compromising the function of the glazing to serve as a window, by creating a light dispersing layer that is substantially invisible when in the off state and very bright in the on state.

Articles and methods related to the cold-forming of glass laminate articles utilizing stress prediction analysis are provided. A cold-forming estimator (CFE) value that is related to the stress experienced by a glass sheet of a glass laminate during cold-forming is calculated based on a plurality of geometric parameters of glass layer(s) of a glass laminate article. The calculated CFE value is compared to a cold-forming threshold related to the probability that defects are formed in the complexly curved glass laminate article during cold-forming. Cold-formed glass laminate articles are also provided having geometric parameters such that the CFE value is below the cold-forming threshold.

The present disclosure relates to bullet-resistant laminated glass having at least three sheets of glass. One of the sheets of glass faces the impact side as a cover sheet, and one sheet of glass is formed as a closure sheet facing away from the impact side. Between the cover sheet and the closure sheet, one or more intermediate sheets are disposed, these sheets of glass being connected to each other by composite layers. The composite layers are formed by flexible and dimensionally unstable films and/or cast compounds. The composite layers do not consist of polycarbonate, polyurethane or polymethylmethacrylate. In order to prevent splinter output on the rear side, this glass composite has a closure sheet on the rear side consisting of thermally or chemically prestressed glass.
