Abstract

A plastic glazing (100) of a tailgate of a vehicle is provided, the plastic glazing (100) comprising: a first translucent component (302); a second translucent component (304) molded onto the first translucent component (302), wherein the second translucent component (304) comprises a color, wherein the plastic glazing (100) is of one-piece molded plastic construction, wherein an overlapping portion of the first translucent component (302) and the second translucent component (304) forms a lens of a first molded light assembly.

Claims

1. A plastic glazing of a tailgate of a vehicle, the plastic glazing comprising:

a first translucent component;

a second translucent component molded onto the first translucent component, wherein the second translucent component comprises a color; and

a third translucent component molded onto the first translucent component, wherein at least a portion of the third translucent component forms a lens of a second molded light assembly,

wherein the plastic glazing is of one-piece molded plastic construction,

wherein a portion of one or more of the first translucent component and the second translucent component forms a lens of a first molded light assembly, and

wherein the portion of the third translucent component forming the lens of the second molded light assembly is configured to operate with the second molded light assembly to produce a white light having a CIE (x,y) chromaticity value within a color space defined by a blue boundary corresponding to x=0.31, a yellow boundary corresponding to x=0.50, a first green boundary corresponding to y=0.15+0.64x, a purple boundary corresponding to v=0.05+0.75x, a second green boundary corresponding to y=0.44, and a red boundary corresponding to y=0.38.

2. The plastic glazing of claim 1, wherein the first molded light assembly comprises a light source that is configured to generate a light that passes through an overlapping portion of the first translucent component and the second translucent component.

3. The plastic glazing of claim 2,

wherein the portion of one or more of the first translucent component and the second translucent component forming the lens of the first molded light assembly is configured to operate with the light source to produce a red light having a CIE (x,y) chromaticity value within a color space defined by a yellow boundary corresponding to y=0.33 and a purple boundary corresponding to y=0.98-x.

4. The plastic glazing of claim 1, wherein a different portion of the first translucent component forms a lens of a third molded light assembly,

wherein the third molded light assembly comprises one of a puddle light, a license plate light, and an interior light.

5. The plastic glazing of claim 1, wherein the portion of one or more of the first translucent component and the second translucent component forming the lens of the first molded light assembly and the portion of the third translucent component forming the lens of the second molded light assembly are adjacent to each other.

6. The plastic glazing of claim 1, wherein the plastic glazing is attached to a housing unit that is configured to support the first molded light assembly,

wherein the housing unit comprises a fiber-reinforced polymer.

7. The plastic glazing of claim 1, wherein at least one of the first translucent component and the second translucent component comprises a textured surface configured to disperse light passing through the overlapping portion of the first translucent component and the second translucent component.

8. The plastic glazing of claim 1, wherein the overlapping portion of the first translucent component and the second translucent component is configured to transmit a light having a percentage of rays that deviates by more than 2.5°

from an incident ray of less than or equal to 30 percent.

9. The plastic glazing of claim 1, wherein the plastic glazing is attached to a housing unit that is configured to support the first molded light assembly.

10. The plastic glazing of claim 1, wherein the plastic tailgate is produced using a multi-shot injection molding process.

11. The plastic glazing of claim 1, wherein the second translucent component is molded onto the first translucent component in a second shot of the multi-shot injection molding process.

12. The plastic glazing of claim 1, wherein the first translucent component forms a raised marking.
