Abstract

An ornamental device including a decorative plated surface and a backlit assembly is described, and includes a light engine including a light-emitting diode (LED), a light pipe optically coupled to the LED, a light diffuser and a lens assembly. The lens assembly includes a chrome surface finish, wherein the lens assembly encases the light engine, the light pipe and the light diffuser, and is assembled onto a back plate. When the LED is not illuminated, the lens assembly exhibits a chrome appearance, and when the LED is illuminated, light emanates through the lens assembly.

Claims (38)

1. An ornamental device including a decorative plated surface and a backlit assembly, comprising:

a light engine including a light-emitting diode (LED);

a light pipe optically coupled to the LED;

a light diffuser; and

a lens assembly including a chrome surface finish, wherein the lens assembly encases the light engine, the light pipe and the light diffuser, and is assembled onto a back plate;

wherein when the LED is not illuminated, the lens assembly exhibits a chrome appearance; and

wherein when the LED is illuminated, light emanates through the lens assembly.

2. The ornamental device of claim 1 , further comprising the light engine including the LED assembled onto the back plate.

3. The ornamental device of claim 1 , further comprising an emblem insert assembled onto and covering a portion an outer surface of the lens assembly.

4. The ornamental device of claim 3 , wherein the emblem insert comprises a translucent element.

5. The ornamental device of claim 3 , wherein the emblem insert comprises an opaque element.

6. The ornamental device of claim 3 , wherein when the LED is not illuminated, the lens assembly exhibits a chrome appearance over a portion of the lens assembly that is not covered by the emblem insert.

7. The ornamental device of claim 3 , wherein when the LED is illuminated, light emanates through the lens assembly through a portion of the lens assembly that is not covered by the emblem insert.

8. The ornamental device of claim 7 , wherein the LED includes a transparent lens, and wherein light emanates through portions of the lens assembly that are not covered by the emblem insert when the LED is illuminated.

9. The ornamental device of claim 7 , wherein the LED includes a colored lens, and wherein non-white light emanates through portions of the lens assembly that are not covered by the emblem insert when the LED is illuminated.

10. The ornamental device of claim 1 , wherein the light engine including an LED further comprises the light engine assembled onto the back plate and electrically connected to an electric power source.

11. The ornamental device of claim 1 , wherein the lens assembly including the chrome surface finish further comprises a coated inner lens including the chrome surface finish sealably assembled within an outer lens.

12. The ornamental device of claim 11 , wherein the outer lens comprises a transparent outer lens.

13. The ornamental device of claim 11 , wherein the outer lens comprises a translucent outer lens.

14. The ornamental device of claim 11 , wherein the coated inner lens comprises a molded element coated with a chrome layer.

15. The ornamental device of claim 14 , wherein the molded element coated with a chrome layer comprises a molded transparent element coated with the chrome layer.

16. The ornamental device of claim 14 , wherein the molded element coated with a chrome layer comprises a molded translucent element coated with the chrome layer.

17. The ornamental device of claim 14 , wherein the molded element coated with the chrome layer further comprises the molded element coated with a chrome layer applied using a physical vapor deposition process.

18. The ornamental device of claim 1 , wherein the light pipe has a shape that approximates the shape of the backlit ornamental device.

19. An ornamental device including a decorative plated surface and a backlit assembly, comprising:

a light engine including a light-emitting diode (LED);

a light pipe optically coupled to the LED;

a light diffuser;

a lens assembly including a chrome surface finish, wherein the lens assembly encases the light engine, the light pipe and the light diffuser, and is assembled onto a back plate; and

an emblem insert covering a first portion of the lens assembly;

wherein when the LED is not illuminated, the lens assembly exhibits a chrome appearance through a second portion of the lens assembly not covered by the emblem insert.

20. An ornamental device including a decorative plated surface and a backlit assembly, comprising:

a light engine including a light-emitting diode (LED);

a light pipe optically coupled to the LED;

a light diffuser;

a lens assembly including a chrome surface finish, wherein the lens assembly encases the light engine, the light pipe and the light diffuser, and is assembled onto a back plate; and

an emblem insert covering a first portion of the lens assembly;

wherein when the LED is illuminated, light emanates through a second portion of the lens assembly not covered by the emblem insert.
