Abstract

A method and apparatus for a curved lighting fixture that is symmetric about a longitudinal axis of the curved lighting fixture. The curved lighting fixture includes end caps that are parallel to the longitudinal axis. Each end cap includes two mounting studs that secure the lighting fixture to mounting brackets, where a first mounting stud provides an axis of rotation for the lighting fixture and a second mounting stud facilitates the rotation. The two mounting studs do not enter into an interior portion of the lighting fixture so as to facilitate externally serviceable hardware. A bushing provides an external retention mechanism to retain the two mounting studs within each end cap.

Claims

1. A lighting system, comprising:

an automotive grille having a first radius of curvature; and

a lighting fixture having a second radius of curvature substantially equal to the first radius of curvature, said lighting fixture including a frame having a curved shape along the length of the frame with a cavity formed therein and a light source positioned within the cavity, wherein the lighting fixture is disposed within the automotive grille.

2. The lighting system of claim 1, wherein an outer surface of the automotive grille is substantially co-planar with an outer surface of the lighting fixture.

3. The lighting system of claim 1, wherein a length of the automotive grille is longer than a length of the lighting fixture.

4. The lighting system of claim 1, wherein a length of the automotive grille is equal to a length of the lighting fixture.

5. The lighting system of claim 1, wherein the lighting fixture is an LED-based lighting fixture.

6. The lighting system of claim 1, wherein the lighting fixture further includes first and second end caps, at least one of the first and second end caps being coupled to the grille for mounting the lighting fixture within the grille.

7. The lighting system of claim 6, wherein said lighting fixture further includes first and second pivot points at the first and second end caps such that the lighting fixture has an axis of rotation about the first and second pivot points that is substantially orthogonal to a longitudinal axis.

8. The lighting system of claim 1, wherein the frame further includes a front surface and a back surface, said back surface having heat dissipating fins extending therefrom, and said front surface having a perimeter ridge extending therefrom for the length of the frame, thereby defining the cavity for containing the light source.

9. A lighting system, comprising:

an automotive grille having a first radius of curvature; and

a lighting fixture having a second radius of curvature substantially equal to the first radius of curvature, said lighting fixture including a frame having a curved shape along the length of the frame with a cavity formed therein and a light source positioned within the cavity, wherein the lighting fixture is integrated with the automotive grille.

10. The lighting system of claim 9, wherein an outer surface of the automotive grille is substantially co-planar with an outer surface of the lighting fixture.

11. The lighting system of claim 9, wherein a length of the automotive grille is longer than a length of the lighting fixture.

12. The lighting system of claim 9, wherein a length of the automotive grille is equal to a length of the lighting fixture.

13. The lighting system of claim 9, wherein the lighting fixture is an LED-based lighting fixture.

14. The lighting system of claim 9, wherein the lighting fixture is rotatable with respect to the automotive grille.

15. A lighting system, comprising:

an automotive grille having a first radius of curvature; and

a lighting fixture having a second radius of curvature substantially equal to the first radius of curvature, said lighting fixture including a frame having a curved shape along the length of the frame with a cavity formed therein and an LED light source positioned within the cavity, wherein the lighting fixture is coupled to the automotive grille.

16. The lighting system of claim 15, wherein an outer surface of the automotive grille is substantially co-planar with an outer surface of the lighting fixture.

17. The lighting system of claim 15, wherein a length of the automotive grille is longer than a length of the lighting fixture.

18. The lighting system of claim 15, wherein a length of the automotive grille is equal to a length of the lighting fixture.
