Abstract

A painted vehicle trim component such as a spoiler, side-view mirror housing, or other vehicle body part is provided with electroluminescent paint to emit light from its surface. The trim component includes a substrate having a mounting surface for attaching to the vehicle. A conductor body is at least partially embedded in the substrate to provide a conductive surface exposed externally of the substrate. A conductive wire is crimped to the conductor body and is adapted to connect to an electrical power source remotely from the vehicle trim component. A conductive bus bar paint layer is deposited over the substrate and onto the exposed conductive surface of the conductor body. A light-emitting paint layer deposited over the substrate is disposed relative to the conductive paint layer such that light is emitted when an electrical signal is received at the conductive wire.

First claim

What is claimed is:

1. A vehicle trim component with electroluminescent lighting, comprising:
a substrate having a mounting surface for attaching to a vehicle;
a conductor body at least partially embedded in the substrate and having a conductive surface exposed externally of the substrate;
a conductive wire connected to the conductor body and adapted to connect to an electrical power source remotely from the vehicle trim component;
a conductive bus bar paint layer deposited over the substrate and onto the exposed conductive surface of the conductor body; and
a light-emitting paint layer deposited over the substrate and disposed relative to the conductive paint layer such that light is emitted when an electrical signal is received at the conductive wire.

2. The vehicle trim component of claim 1 wherein the substrate is comprised of molded plastic.

3. The vehicle trim component of claim 2 wherein the molded plastic substrate is blow molded onto the conductor body.

4. The vehicle trim component of claim 2 wherein the molded plastic substrate is injection molded onto the conductor body.

5. The vehicle trim component of claim 1 wherein the conductive surface of the conductor body is slanted with respect to an outer surface of the substrate so that the conductive surface projects outwardly from the substrate.

6. The vehicle trim component of claim 1 wherein the conductor body is comprised of a metal spade with a crimped end holding the conductive wire.

7. The vehicle trim component of claim 1 comprising at least two conductor bodies and at least two conductive paint layers separately deposited on the conductor bodies for applying an alternating electric field across the light-emitting paint layer.

8. The vehicle trim component of claim 7 further comprising a conductive clear paint layer in contact with the conductive bus bar paint layer.

9. The vehicle trim component of claim 1 wherein the substrate has a show surface opposing the mounting surface, and wherein the conductive surface of the conductor body is exposed within the mounting surface.

10. The vehicle trim component of claim 1 further comprising a protective adhesive body disposed over the conductive bus bar paint layer.

11. The vehicle trim component of claim 10 wherein the protective adhesive body is comprised of a mastic tape.

12. The vehicle trim component of claim 1 further comprising a shielding plate disposed over the conductive bus bar paint layer.

13. A painted article with electroluminescent lighting, comprising:
a plastic molded substrate having a show surface and a connection surface;
first and second conductor bodies at least partially embedded in the substrate and having first and second conductive surfaces exposed externally at the connection surface;
first and second conductive wires each connected to a respective conductor body within the substrate and extending from the substrate to connect to an electrical power source;
a conductive backplane paint layer deposited over the show surface and onto the exposed first conductive surface of the first conductor body;
a conductive bus bar paint layer deposited over the substrate and onto the exposed second conductive surface of the second conductor body;
a conductive clear paint layer deposited over the show surface and contacting the conductive bus bar paint layer; and
a light-emitting paint layer deposited over the show surface and disposed between the conductive backplane paint layer and the conductive clear paint layer such that light is emitted when an electrical signal is received at the first and second conductive wires.

14. The article of claim 13 wherein the first and second conductive surfaces are slanted with respect to an outer surface of the substrate so that the first and second conductive surfaces project outwardly from the substrate.

15. The article of claim 13 wherein the first and second conductor bodies are each comprised of a metal spade with a crimped end holding a respective conductive wire.
