Abstract

This disclosure details illuminating vehicle closure member systems for selectively producing various exterior lighting effects. Exemplary closure member systems may include a closure member and a discrete illuminating section secured relative to the closure member and including a lighting module that is configured to produce at least one of a beltline lighting effect, a motion path lighting effect, or an operation status lighting effect at or near the closure member. A control module may control the various lighting effects emitted by the illuminating closure member system.

First claim

What is claimed is:

1. An illuminating closure member system, comprising:
a closure member; and
a discrete illuminating section secured relative to the closure member and including a lighting module configured to illuminate a beltline of the closure member,
wherein the lighting module is configured to provide an illuminating sequence along the beltline,
wherein a direction of the illuminating sequence along the beltline is based on a direction of an approach of an authorized user.

2. The illuminating closure member system as recited in claim 1 , wherein the closure member is a vehicle side door.

3. The illuminating closure member system as recited in claim 1 , comprising a control module configured to control the lighting module for illuminating the beltline when the authorized user is within a threshold range from the closure member.

4. The illuminating closure member system as recited in claim 3 , comprising an authorization sensor in communication with the control module and configured to communicate with a personal electronic device of the user when the personal electronic device is within the threshold distance.

5. The illuminating closure member system as recited in claim 3 , comprising a positional sensor in communication with the control module and configured to detect a user gesture from the authorized user, and further comprising an object detection sensor in communication with the control module and configured to detect an object in a motion path of the closure member.

6. The illuminating closure member system as recited in claim 1 , wherein a rate at which the illuminating sequence moves along the beltline is based on a speed of the approach of the authorized user.

7. The illuminating closure member system as recited in claim 1 , comprising an actuator system configured to move the closure member between a closed position and an open position, wherein the actuator system includes a power door actuator.

8. The illuminating closure member system as recited in claim 1 , wherein the illuminating sequence includes a pulsing or chasing pattern.

9. The illuminating closure member system as recited in claim 1 , wherein the discrete illuminating section includes the lighting module and a thermal transfer device positioned between the lighting module and a metallic component of the closure member, wherein the thermal transfer device includes a thermally conductive adhesive pad that facilitates heat transfer between a printed circuit board (PCB) of the lighting module and the metallic component.

10. The illuminating closure member system as recited in claim 1 , wherein the lighting module is configured to start or stop the illuminating sequence at a location along the beltline closest to where the authorized user has started or stopped during the approach.

11. The illuminating closure member system as recited in claim 1 , wherein the lighting module is configured to illuminate the beltline in order to indicate an operation status of the closure member.

12. The illuminating closure member system as recited in claim 1 , wherein the lighting module is configured to project an illuminated motion path that provides a visual indication of an expected path of motion of the closure member.

13. The illuminating closure member system as recited in claim 1 , wherein the lighting module is configured to provide the illuminating sequence at a first brightness when the closure member is positioned at a first angle relative to a vehicle body and is further configured to provide the illuminating sequence at a second brightness that is greater than the first brightness when the closure member is positioned at a second angle relative to the vehicle body, wherein the second angle is larger than the first angle.

14. The illuminating closure member system as recited in claim 9 , wherein the PCB includes a glass-reinforced epoxy laminate panel that is positioned in contact with the thermal transfer device.

15. A vehicle, comprising:
a vehicle body;
a closure member movably mounted relative to the vehicle body;
an illuminating closure member system mounted to the closure member; and
a control module configured to control the illuminating closure member system for producing at least one of a beltline lighting effect,
wherein the at least one beltline lighting effect includes an illuminating sequence provided along the beltline of the closure member,
wherein a direction of the illuminating sequence along the beltline is based on a direction of an approach of an authorized user.

16. The vehicle as recited in claim 15 , wherein the illuminating closure member system includes a lighting module and a thermal transfer device disposed between the lighting module and a metallic component of the closure member, wherein the lighting module includes a diffuser lens, a plurality of light sources, and a printed circuit board (PCB), and the thermal transfer device includes a thermally conductive adhesive pad that facilitates heat transfer between the PCB and the metallic component.

17. The vehicle as recited in claim 16 , wherein the control module is configured to control the lighting module for producing the beltline lighting effect when the authorized user is within a threshold range from the vehicle, and comprising an authorization sensor configured to communicate an input signal to the control module when the authorized user is within the threshold range.

18. The vehicle as recited in claim 15 , comprising a reflective panel configured to reflect a motion path lighting effect produced by the illuminating closure member system onto a ground surface adjacent the vehicle.

19. The vehicle as recited in claim 15 , wherein a motion path lighting effect produced by the illuminating closure member system includes a logo, a sweeping illuminated line, or a colored illuminated line.

20. A method, comprising:
automatically illuminating at least a portion of a beltline of a closure member of a vehicle with an illuminating closure member system when an authorized user is within a threshold distance of the vehicle,
wherein illuminating the portion of the beltline includes providing an illuminating sequence along the beltline,
wherein a direction of the illuminating sequence along the beltline is based on a direction of an approach of the authorized user.
