Abstract

A lighting system for a trailer assembly is provided herein. The lighting system includes a hitch angle detection component having a predefined pattern thereon. A light source is disposed within the hitch angle detection component. A photoluminescent structure is disposed on the light source. The photoluminescent structure is configured to luminesce in response to excitation by light output from at least a portion of the light source.

Claims (35)

1. A lighting system for a trailer, comprising:

a hitch angle detection component disposed on a trailer;

a light source disposed within the detection component;

a first photoluminescent structure disposed on the light source and configured to luminesce in response to excitation by the light source; and

a second photoluminescent structure separated from the light source and disposed on a trailer feature, wherein the second photoluminescent structure luminesces in response to light output from the light source.

2. The lighting system for a trailer of claim 1 , wherein the light source comprises a plurality of printed LEDs.

3. The lighting system for a trailer of claim 2 , wherein the photoluminescent structure comprises at least one photoluminescent material configured to convert an inputted light received from at least a portion of the light source into a visible light that is outputted to a viewable portion.

4. The lighting system for a trailer of claim 3 , wherein the inputted light comprises one of blue light, violet light, and UV light.

5. The lighting system for a trailer of claim 1 , wherein the hitch angle detection component is configured as a target.

6. The lighting system for a trailer of claim 5 , wherein the target cooperates with a trailer backup assist function of a vehicle.

7. The lighting system for a trailer of claim 1 , wherein the hitch angle detection component includes a predetermined image pattern of a certain size and shape provided on a top surface for capture by a video camera and recognition by an image processing unit.

8. A trailer system, comprising:

a hitch angle detection component having a light source; and

a first luminescent structure disposed on the light source and configured to luminesce in a first color in response to excitation by the light source when a motion detection unit detects a trailer is in motion and in a second, different color when the motion detection unit detects the trailer is stationary.

9. The trailer system of claim 8 , wherein the light source comprises a printed LED.

10. The trailer system of claim 8 , wherein the light source is powered by a power source disposed within a vehicle and is configured to illuminate when the vehicle is placed in reverse.

11. The trailer system of claim 9 , wherein the first luminescent structure comprises at least one luminescent material configured to convert an inputted light received from at least a portion of the printed LED into a visible light that is outputted to a viewable portion.

12. The trailer system of claim 8 , further comprising:

a second luminescent structure separated from the light source.

13. The trailer system of claim 12 , wherein the first luminescent structure illuminates in a first color and the second luminescent structure illuminates in a second color.

14. The trailer system of claim 8 , wherein the light source is powered by a power source within the hitch angle detection component.

15. A lighting system for a trailer assembly, comprising:

a hitch angle detection component having a pattern thereon on a trailer component;

a light source disposed within the hitch angle detection component;

a photoluminescent structure disposed on the light source, wherein the photoluminescent structure is configured to luminesce in response to excitation by light output from the light source; and

an overmold material disposed over the photoluminescent structure configured to encapsulate the light source and photoluminescent structure between the overmold material and trailer component.

16. The lighting system for a trailer assembly of claim 15 , wherein the light source comprises a plurality of printed LEDs.

17. The lighting system for a trailer assembly of claim 15 , further comprising:

a photosensor configured to measure incident light; and

a controller configured to maintain a constant intensity of light emitted from the detection component based on a lighting condition of the hitch angle detection component.

18. The lighting system for a trailer assembly of claim 17 , further comprising:

a solar panel connected to a power source disposed within the hitch angle detection component.

19. The lighting system for a trailer assembly of claim 15 , further comprising:

a motion detection unit disposed on the hitch angle detection component configured to detect a positional change of the trailer.

20. The lighting system for a trailer assembly of claim 19 , wherein the light source is illuminated when the motion detection unit senses movement of the trailer and returns to an unilluminated state if no motion is sensed for a predetermined amount of time thereafter.
