Abstract

Systems and methods for providing adequate lighting and sighting for a bicycle are disclosed. A lighting system that includes an illumination ring configured to be coupled to a wheel is also disclosed. The illumination ring is configured to simultaneously project light forward and to the side of a front wheel and to project light rearward of and to the side of a rear wheel. The illumination ring may be mounted to or integrated with the bicycle wheel. Methods of controlling light sources on the illumination ring are also disclosed.

Claims

1. A lighting system for a wheel, comprising:

a plurality of light emitting elements configured to statically couple to the wheel;

a controller coupled to the light emitting elements that controls each of the light emitting elements to operate between;

a lit mode wherein the light emitting element projects light radially outward of the wheel when the light emitting element is within an arcuate area defined from a reference point, the arcuate area having an arc length of less than 360 degrees; and

a dim mode when the light emitting element is outside the arcuate area; and

an electrical connector that connects the controller to the light emitting elements.

2. The lighting system of claim 1, wherein the wheel includes a center plane extending along a wheel circumference and encompassing a midpoint of the wheel, wherein the plurality of light emitting elements are configured to project light along a vector substantially parallel to the center plane.

3. The lighting system of claim 2, wherein the plurality of light emitting elements are configured to project light along a second vector that intersects the center plane.

4. The lighting system of claim 1, further comprising:

a second plurality of light emitting elements configured to couple to the wheel opposing the first plurality of light emitting elements across the wheel, each light emitting element of the second plurality operable between a lit mode when the light emitting element is within the arcuate area and a dim mode when the light emitting element is outside the arcuate area.

5. The lighting system of claim 4, wherein the controller is configured to control operation of the first and second pluralities of light emitting elements between the lit and dim modes.

6. The lighting system of claim 5, wherein the controller is directly connected to the second plurality of light emitting elements.

7. The lighting system of claim 1, wherein the controller is connected to the first plurality of light emitting elements from a hub of the wheel.

8. The lighting system of claim 7, wherein the controller is mounted to the hub of the wheel.

9. The lighting system of claim 1, further comprising a support mounted to the plurality of light emitting elements and configured to mount the light emitting elements to the wheel.

10. The lighting system of claim 9, wherein the support comprises translucent material.

11. The lighting system of claim 1, further comprising a power source electrically connected to the plurality of light emitting elements.

12. The lighting system of claim 11, wherein the power source is electrically connected to the light emitting elements from a hub of the wheel.

13. The lighting system of claim 11, wherein the power source is configured to mount to a frame of a vehicle supporting the wheel.

14. The lighting system of claim 13, wherein the power source is configured to mount to a fork of the frame.

15. The lighting system of claim 14, further comprising a plurality of induction coils configured to mount to the wheel, each induction coil having a coil plane perpendicular to a winding axis;

wherein the power source comprises a magnet configured to mount to the frame such that an electric field is generated perpendicular to the coil plane during wheel rotation.

16. The lighting system of claim 15, wherein the power source further comprises a capacitor electrically connected to each of the plurality of induction coils.

17. The lighting system of claim 15, further comprising:

a second support configured to statically mount to the wheel, offset from the center plane and opposing the first support; and

a second plurality of light emitting elements, each light emitting element of the second plurality operable between a first lighting state when the light emitting element is within the arcuate area and a second lighting state when the light emitting element is outside the arcuate area;

wherein the plurality of induction coils are supported by the first support.

18. A lighting system for a wheel, the wheel having a center plane extending along a wheel circumference and encompassing a midpoint of the wheel, the lighting system comprising:

a support configured to statically mount to the wheel offset from the center plane; and

a plurality of light emitting elements mounted to the support, each light emitting element operable between;

a first lighting state when the light emitting element is within an arcuate area defined from a reference point, the arcuate area having an arc length of less than 360 degrees, wherein the light emitting element projects light radially outward of the wheel; and

a second lighting state when the light emitting element is outside the arcuate area.

19. The lighting system of claim 18, further comprising:

a second support configured to statically mount to the wheel offset from the center plane opposing the first support across the wheel; and

a second plurality of light emitting elements, each light emitting element of the second plurality operable between a first lighting state when the light emitting element is within the arcuate area and a second lighting state when the light emitting element is outside the arcuate area.

20. The lighting system of claim 19, further comprising a power source configured to power the first and second pluralities of light emitting elements, the power source comprising a plurality of induction coils configured to mount to the wheel, each induction coil having a coil plane perpendicular to a winding axis, and a magnet that mounts to a frame of a vehicle supporting the wheel in an orientation wherein an electric field is generated perpendicular to the coil plane during wheel rotation.
