Abstract
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.
