Abstract

A lighting apparatus for an automobile generally includes a projection device coupled to the automobile (e.g., an external component, such as a door handle assembly) wherein the projection device is configured to project an image onto a display surface that is external to the automobile (e.g., the ground adjacent to a door of the automobile or a region near the door handle itself). The lighting apparatus is configured to activate in response to one or more events, such as proximity of a key fob, the unlocking of one or doors, or the like.

Claims

1. A lighting apparatus for an automobile, comprising:

a projection device coupled to the automobile;

wherein the projection device is configured to project an image onto a display surface that is external to the automobile.

2. The apparatus of claim 1, wherein the display surface is an external surface of the body of the automobile.

3. The apparatus of claim 2, wherein the external surface is a generally concave surface adjacent an outside handle assembly of the automobile.

4. The apparatus of claim 1, wherein the display surface is a region on the ground adjacent the automobile.

5. The apparatus of claim 4, wherein the display surface is adjacent a side door of the automobile.

6. The apparatus of claim 1, wherein the projection device is integrated into an outside handle assembly of the automobile.

7. The apparatus of claim 6, wherein the outside handle assembly includes a door handle lever, and wherein the projection device is integrated into the door handle lever and is configured to project the image generally downward with respect to the automobile.

8. The apparatus of claim 7, wherein the projection device includes a light emitting diode configured to emit light toward the display surface along an optical path.

9. The apparatus of claim 8, wherein the projection device includes an optical component between the light emitting diode and the display surface, and wherein the optical component bears a graphical design corresponding to the image.

10. The apparatus of claim 9, wherein the optical component is a laser-etched lens.

11. The apparatus of claim 9, further including a condenser lens between the light emitting diode and the optical component.

12. The apparatus of claim 11, further including a focusing lens between the optical component and the display surface.

13. The apparatus of claim 12, wherein the condenser lens, light emitting diode, optical component, and focusing lens are aligned axially within a clamshell housing structure.

14. The apparatus of claim 1, wherein the image includes indicia selected from the group consisting of automotive brand indicia and automotive type indicia.

15. The apparatus of claim 1, further including a controllable power source coupled to and configured to activate the projection device.

16. The apparatus of claim 1, wherein the power source is configured to activate the projection device when one or more doors of the automobile are unlocked.

17. An outside handle assembly for an automobile comprising:

a lighting apparatus including a projection device configured to project an image onto a display surface external to the automobile, wherein the projection device includes a light emitting diode configured to emit light toward the display surface along an optical path, and an emblem component positioned between the light emitting diode and the display surface such that projected image corresponds to the emblem component; and

a power source coupled to the lighting apparatus and configured to selectively activate the lighting apparatus in response to one or more user-generated event.

18. The assembly of claim 17, wherein the external surface is a region on the ground adjacent the automobile, and wherein the user-generated event includes unlocking the outside handle assembly.

19. A method for providing external lighting for an automobile, the method comprising:

receiving a user-generated event associated with the automobile; and

projecting an image on a display surface external to the automobile in response to the user-generated event.

20. The method of claim 19, wherein:

the user-generated event includes unlocking a door of the automobile;

the display surface includes a ground surface adjacent to the door of the automobile; and

the image includes indicia associated with a brand or a type of the automobile.
