The disclosure refers to an encapsulated illuminated glazing in which a cavity is first formed in the encapsulation and then, after completion of the encapsulation, the light strip is slid into and installed in the cavity.

Encapsulated illuminated automotive glazing and method of producing thereof

Vehicle glazing, which once served just to provide for vision and protect from the elements, has been taking on new functions as the complexity and functionality of modern automobiles has evolved. Performance films and interlayers are often used to add to and enhance the functionality of laminates. These functions include solar control, sound dampening, head up display and variable light transmittance. Recent advances have made it possible to produce electronic circuits on thin transparent substrates that are essentially invisible under normal lighting conditions. While these circuits can be inserted into the laminate and successfully laminated, the edges of the circuit insert are prone to objectionable aesthetics due to mismatch between the substrate and the interlayer index of refraction, thickness and color. The present invention compensates the edge of the solid insert by providing a sheet of a compatible compensation material that the substrate of the insert and which extends to at least the black band or the edge of glass of the laminate making the insert edge essentially invisible.

Invisible edge solid substrate compensation layer for automotive glazing

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.

Illuminated laminate with superior aesthetics and brightness

The price and performance of LED lighting have reached the point where LEDs are displacing more traditional lighting. Even though LED lifetimes are as high as 50,000 hours, they are still being designed as replaceable bulbs rather than being integrated as a permanent part of the lighting assembly. The invention provides for a means of economically producing laminated glass with integrated LED lighting designed to last the life of the vehicle. This is done by embedding the LED die into the plastic layer used to bond the glass layers of a laminate together, forming an embedded wire circuit from thin high tensile strength Tungsten wire to power the LEDs and by utilizing machine tool technology originally developed to produce integrated circuit assemblies such as RFID ID cards, tickets and passports.
