The first ply of glazing material comprises a sheet of glass having a first composition and the second ply of glazing material comprises a sheet of glass having a second composition different to the first composition. The laminated glazing has (i) a peripheral region extending around the periphery of the laminated glazing, the laminated glazing having a surface compression stress in the peripheral region and (ii) an edge compression, wherein the magnitude of edge compression is greater than the magnitude of the surface compression stress in the peripheral region. A method of making such a laminated is provided. A glass sheet suitable for being incorporated in such a laminated glazing is also disclosed.

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.

Laminated structures include a thin glass sheet with a thickness of less than 600 μm being attached to a metal sheet with an adhesive layer including a thickness of about 100 μm or less. These laminated structures can include planar or curved shapes. Methods of manufacturing a laminated structure are also provided including the step of attaching a glass sheet with a thickness of less than 600 μm to a metal sheet with an adhesive layer including a thickness of about 300 μm or less.

The present approaches are in the in the field of vacuum (or pneumatic) elevators, where the elevator cabin is brought into motion in a vertically situated or vertically inclined and hermetically sealed elevator shaft by means of aerial pressure differential above and below the elevator cabin. Such approaches do not require having any ropes, pulleys, chains, gears, or hydraulics that are traditionally used in conventional elevator systems. More specifically, the present approaches are in the field of panoramic vacuum elevators, where the elevator hoistway is built of panoramic glass panels running from floor to ceiling of every floor and the elevator cabin is built of panoramic glass panels running from floor to the ceiling of the cabin, and that this type of elevator does not incorporate any metal constructive structures—frames, mesh, guides or rails that are traditionally used in every conventional elevator product.
