Abstract

A vehicle lamp assembly includes an LED disposed on a circuit board, a light collimator operatively coupled to the LED to generate a beam of collimated light, a light pipe operatively coupled to light collimator to transmit the collimated beam of light, and a hybrid optic lens operatively coupled to the light pipe to diverge the collimated beam of light into a beam pattern. The hybrid optic lens includes a plurality of curved lenses for outputting light in a first direction, a first prism lens formed on a lower portion of the curved lenses for directing light downward in a second direction, and a second prism lens provided on a lateral side of curved lenses for directing light sideways in a third direction. An enhanced light illumination with uniform lighting pattern in the trailer hitch target region is achieved for operation of a trailer with the vehicle.

Claims (45)

1. A lamp assembly comprising:

a circuit board;

a light source disposed on the circuit board;

a light collimator operatively coupled to the light source to generate a collimated beam of light; and

a hybrid optic lens operatively coupled to receive the collimated beam of light and output the light in a beam pattern, the hybrid optic lens comprising:

a plurality of curved lenses each having a curved surface for outputting light within the beam pattern in a first direction;

a first prism lens formed on a first side of at least some of the plurality of the curved lenses for directing light in a second direction; and

a second prism lens provided on a lateral second side of at least some of the plurality of curved lenses for directing light in a third direction.

2. The lamp assembly of claim 1 further comprising a light pipe operatively coupled between the light collimator and the hybrid optic lens to transmit the beam of collimated light.

3. The lamp assembly of claim 2 , wherein the light pipe comprises a straight light pipe.

4. The lamp assembly of claim 3 , wherein the hybrid optic lens is integrally formed with the light pipe.

5. The lamp assembly of claim 4 , wherein the light collimator is integrally formed with the light pipe.

6. The lamp assembly of claim 1 , wherein the curved surface of each of the plurality of curved lenses provides a pillow lens.

7. The lamp assembly of claim 1 , wherein the hybrid optic lens diverges the light to form a divergent beam pattern.

8. The lamp assembly of claim 1 , wherein the light source comprises an LED.

9. The lamp assembly of claim 1 , wherein the lamp assembly is located on a vehicle.

10. The lamp assembly of claim 9 , wherein the lamp assembly is located to illuminate light rearward of the vehicle.

11. The lamp assembly of claim 10 , wherein the lamp assembly is oriented downward at an angle relative to the vehicle.

12. A vehicle lamp assembly comprising:

a circuit board;

an LED disposed on the circuit board;

a light collimator operatively coupled to the LED to generate a beam of collimated light;

a light pipe operatively coupled to light collimator to transmit the collimated beam of light; and

a hybrid optic lens operatively coupled to the light pipe to receive the collimated beam of light and output the light in a divergent beam pattern, the hybrid optic lens comprising:

a plurality of curved lenses each having a curved surface for outputting light within the divergent beam pattern in a first direction;

a first prism lens formed on a lower portion of at least some of the plurality of curved lenses for directing light downward in a second direction; and

a second prism lens provided on a lateral side of at least some of the plurality of curved lenses for directing light sideways in a third direction.

13. The lamp assembly of claim 12 , wherein the lamp assembly is oriented to illuminate light rearward of the vehicle.

14. The lamp assembly of claim 13 , wherein the lamp assembly is oriented downward at an angle relative to the vehicle.

15. A vehicle comprising:

a body;

an imaging device; and

a lamp assembly comprising:

a circuit board;

a light source disposed on the circuit board;

a light collimator operatively coupled to the light source to generate a beam of collimated light; and

a hybrid optic lens operatively coupled to receive the collimated light, the hybrid optic lens comprising:

a plurality of curved lenses each having a curved surface for generating a beam pattern in a first direction;

a first prism lens formed on a first side of at least some of the plurality of optical element lenses for directing light in a second direction; and

a second prism lens located on a lateral side of at least some of the plurality of optical members for directing light sideways in a third direction.

16. The vehicle of claim 15 , wherein the vehicle further comprises a trailer hitch, wherein the light illuminates a region proximate to the trailer hitch.

17. The vehicle of claim 16 , wherein the vehicle further comprises a trailer backup assist system for assisting with the operation of a trailer with the vehicle.

18. The vehicle of claim 17 , wherein the imaging device and the lamp assembly are located on the vehicle to capture images in the region rearward of the vehicle.

19. The vehicle of claim 18 , wherein the imaging device and the lamp assembly are laterally offset from one another.

20. The vehicle of claim 15 , wherein the lamp assembly further comprises a light pipe, operatively coupled between the light collimator and the hybrid optic lens to transmit the beam of collimated light, wherein the hybrid optic lens diverges the light to form a divergent beam pattern.
