Abstract

A vehicle window glazing is provided that includes a transparent substrate defining a first surface with a decorative layer positioned on the first surface defining an indicium. A light source is positioned on the decorative layer. A conductive lead is electrically coupled to the light source and extends along the first surface of the substrate away from the light source. The at least one conductive lead is substantially transparent and a transparent layer is positioned over the decorative layer and substrate.

Claims

1. A vehicle window glazing, comprising:

a transparent substrate of a vehicle window defining a first surface;

a decorative layer positioned on the first surface defining an indicium;

a light source positioned on the decorative layer;

at least one substantially transparent conductive lead electrically coupled to the light source and extending along the first surface of the substrate away from the light source; and

a transparent layer positioned over the decorative layer and the substrate.

2. The vehicle window glazing of claim 1, further comprising:

an adhesive layer positioned between the first surface of the substrate and the decorative layer.

3. The vehicle window glazing of claim 1, wherein a portion of the decorative layer is translucent.

4. The vehicle window glazing of claim 1, further comprising:

a photoluminescent layer positioned on the decorative layer.

5. The vehicle window glazing of claim 1, wherein the light source is a printed light emitting diode and is positioned between the decorative layer and the first surface of the substrate.

6. The vehicle window glazing of claim 5, wherein the conductive lead comprises indium tin oxide.

7. The vehicle window glazing of claim 6, wherein the light source is configured to illuminate the indicium of the decorative layer.

8. The vehicle window glazing of claim 7, wherein the transparent layer comprises silicone.

9. A vehicle window glazing, comprising:

a substantially transparent substrate of a vehicle window defining first and second surfaces;

a decorative layer positioned on the first surface defining an indicium which is raised relative to the decorative layer;

a first silicone layer positioned over the decorative layer and the first surface of the substrate, wherein a light source is disposed within the first silicone layer for illuminating the decorative layer; and

a second silicone layer positioned over the second surface.

10. The vehicle window glazing of claim 9, wherein the first and second silicone layers are configured to reduce audio power transfer through the vehicle window glazing by greater than 5 dB.

11. The vehicle window glazing of claim 10, wherein the first and second silicone layers are configured to reduce audio power transfer through the vehicle window glazing by greater than 10 dB.

12. The vehicle window glazing of claim 9, wherein the first and second silicone layers have a thickness in a range of 0.25 mm to 0.5 mm.

13. The vehicle window glazing of claim 12, wherein the substantially transparent substrate has a thickness in a range of 1.0 mm and 7.0 mm.

14. A vehicle window glazing, comprising:

a substantially transparent substrate of a vehicle window defining a first surface;

a decorative layer positioned on the first surface, the decorative layer defining an indicium which is raised relative to the decorative layer;

a phosphorescent layer positioned between the decorative layer and the substrate; and

a substantially transparent conductive lead electrically coupled to a light source and extending along the first surface away from the light source.

15. The vehicle window glazing of claim 14, further comprising a first transparent polymeric layer which extends over the decorative layer and the first surface of the substantially transparent substrate.

16. The vehicle window glazing of claim 15, further comprising:

the light source configured to emit light through the decorative layer.

17. The vehicle window glazing of claim 16, wherein the first transparent polymeric layer comprises silicone.

18. The vehicle window glazing of claim 17, wherein the decorative layer comprises a metallic foil.

19. The vehicle window glazing of claim 18, wherein the decorative layer defines an indicium which is raised relative to the decorative layer.

20. The vehicle window glazing of claim 19, further comprising:

a second transparent polymeric layer positioned on a second surface of the substrate.
