Abstract

Vehicle exterior lighting systems may be equipped with fascia mounted lamp assemblies. The proposed systems are capable of controlling a fascia lamp assembly to reveal the lamp assembly within the vehicle fascia and then produce various lighting effects based on sensed vehicle conditions. Exemplary fascia lamp assemblies may include a conductive lens that can be charged in order to reveal the lamp assembly within the vehicle fascia.

First claim

What is claimed is:

1. A vehicle exterior lighting system, comprising:
a fascia; and
a fascia lamp assembly that is revealable within the fascia,
wherein the fascia lamp assembly is transitionable between an inactive state in which the fascia lamp assembly is disguised from view within the fascia and an active state in which the fascia lamp assembly is revealed within the fascia.

2. The system as recited in claim 1 , wherein the fascia lamp assembly matches a color of the fascia when in the inactive state.

3. The system as recited in claim 1 , wherein the fascia lamp assembly includes a power source and a conductive inner lens, and further wherein the power source is configured to apply an electrical charge to the conductive inner lens for transitioning the fascia lamp assembly from the inactive state to the active state.

4. The system as recited in claim 3 , wherein the conductive inner lens is configured to convert from a first color to clear in response to receiving the electrical charge.

5. The system as recited in claim 3 , wherein the fascia lamp assembly includes a lighting module that includes a plurality of light emitting diodes (LEDs) that are controllable for providing various lighting effects.

6. The system as recited in claim 3 , wherein the fascia lamp assembly includes an outer lens that includes a lens body and an outer rim.

7. The system as recited in claim 6 , wherein the outer rim facilitates connection of the outer lens to the fascia such that the lens body is positioned flush to the fascia.

8. The system as recited in claim 1 , comprising an illumination control module programmed to control the fascia lamp assembly between the active state and the inactive state in response to receiving signals from a sensor system indicative of a vehicle condition, and further wherein the illumination control module is programmed to command a lighting module of the fascia lamp assembly to provide a specific lighting function adapted for visually indicating the vehicle condition.

9. The system as recited in claim 1 , wherein the fascia is a flexible plastic structure that at least partially conceals a vehicle bumper beam, and further wherein the vehicle exterior lighting system includes a head lamp assembly that is separate from the fascia lamp assembly.

10. A vehicle, comprising:
a fascia; and
a fascia lamp assembly that is revealable within the fascia,
wherein the fascia lamp assembly includes an outer lens that is positioned flush to the fascia.

11. The vehicle as recited in claim 10 , comprising:
a control module programmed to command the fascia lamp assembly between an inactive state and an active state,
wherein, in the inactive state, the fascia lamp assembly is disguised from view within the fascia,
wherein, in the active state, the fascia lamp assembly is revealed within the fascia.

12. The vehicle as recited in claim 11 , wherein the control module is further programmed to command that an electrical charge be applied to a conductive inner lens of the fascia lamp assembly for transitioning the fascia lamp assembly from the inactive state to the active state.

13. The vehicle as recited in claim 12 , wherein the conductive inner lens is configured to convert from a first color to a second color in response to receiving the electrical charge.

14. The vehicle as recited in claim 13 , wherein the first color matches a color of the fascia and the second color is clear.

15. The vehicle as recited in claim 12 , wherein the control module is further programmed to command a lighting module of the fascia lamp assembly to provide a specific lighting function adapted for visually indicating a sensed vehicle condition.

16. The vehicle as recited in claim 15 , wherein the lighting function includes at least one of a parking light effect, a sidemarker lighting effect, an autonomous lighting effect, a hazard marker lighting effect, a greeting lighting effect, or a farewell lighting effect.

17. The vehicle as recited in claim 10 , wherein the outer lens is a two-shot molded outer lens that includes a lens body and an outer rim, and further wherein the outer rim facilitates connection of the outer lens to the fascia such that the lens body is positioned flush to the fascia.

18. The vehicle as recited in claim 17 , wherein the fascia is comprised of a thermoplastic polyolefin (TPO), the lens body is comprised of an acrylic material, and the outer rim is comprised of a thermoplastic polyurethane (TPU).

19. The vehicle as recited in claim 10 , wherein the fascia at least partially conceals a bumper beam of a front end assembly of the vehicle.

20. A vehicle, comprising:
a static body structure;
a head lamp assembly mounted relative to the static body structure;
a fascia supported by the static body structure and made of a first material;
a fascia lamp assembly that is revealable within the fascia,
wherein the fascia lamp assembly is transitionable between an inactive state in which the fascia lamp assembly is disguised from view within the fascia and an active state in which the fascia lamp assembly is revealed within the fascia,
wherein the fascia lamp assembly includes an outer lens that is positioned flush to the fascia, and
wherein the outer lens includes a lens body made of a second material and an outer rim made of a third material, wherein the third material is more compatible with the first material than the second material for facilitating connection of the outer lens to the fascia.
