Abstract

The present invention is directed to a steering apparatus for a vehicle having a including a light element providing indication and warning light signals to the user of the vehicle. The light element can be associated with a PCB mounted to the steering wheel grip for controlling the operation of the light element. The PCB may be thermally coupled to a heat exchange component such that heat from the light element is transferred from the PCB to the steering wheel grip.

Claims

1. A light bar system for a steering wheel comprising:

at least one light source disposed adjacent a portion of an armature of the steering wheel; and

a light diffusing layer having an inner surface and an outer surface,

wherein light is diffused as it passes through the light diffusing layer from the inner surface to the outer surface, the inner surface of the light diffusing layer is disposed adjacent the light source, and the light exiting the outer surface appears as a continuous stream of light across the outer surface of the light diffusing layer.

2. The light bar system of claim 1, further comprising:

an outer lens, an outer surface of the outer lens facing a driver and an inner surface of the outer lens facing the outer surface of the light diffusing layer.

3. The light bar system of claim 2, wherein the light diffusing layer diffuses ambient light that enters the outer lens and is reflected from a surface of the light bar system prior to the reflected ambient light being emitted through the outer lens toward the driver.

4. The light bar system of claim 1, wherein a lens is disposed between the light source and the diffusing layer to guide the light emitted from the light source towards a driver.

5. The light bar system of claim 2, wherein the light diffusing layer is a light diffusing film,

wherein the system further comprises an additional light altering film disposed between the at least one light source and the outer lens.

6. The light bar system of claim 5, wherein the additional light altering film includes at least one of a brightness enhancing film and a second light diffusing film.

7. The light bar system of claim 6, wherein the additional light altering film is a brightness enhancing film, and

the brightness enhancing film is disposed between the light source and the light diffusing layer.

8. The light bar system of claim 7, further comprising a lens to guide the light emitted from the light source towards the driver, the lens is disposed adjacent the light source such that the lens is between the light source and the outer lens,

wherein the brightness enhancing film is disposed adjacent the lens, such that the brightness enhancing film is disposed between the lens and the diffusing film.

9. A light bar system for a steering wheel comprising:

at least one light source disposed adjacent a portion of an armature of the steering wheel; and

a light diffusing layer having an inner surface and an outer surface,

wherein light is diffused as it passes through the light diffusing layer from the inner surface to the outer surface, the inner surface of the light diffusing layer is spaced apart from the light source such that an air gap is defined between the inner surface and the light source, and the light exiting the outer surface appears as a continuous stream of light across the outer surface of the light diffusing layer.

10. The light bar system of claim 9, further comprising:

an outer lens, an outer surface of the outer lens facing a driver and an inner surface of the outer lens facing the outer surface of the light diffusing layer.

11. The light bar system of claim 10, wherein the light diffusing layer diffuses ambient light that enters the outer lens and is reflected from a surface of the light bar system prior to the reflected ambient light being emitted through the outer lens toward the driver.

12. The light bar system of claim 9, wherein the light diffusing layer is a light diffusing film, and the system further comprises an additional light altering film disposed between the at least one light source and the outer lens.

13. The light bar system of claim 12, wherein the additional light altering film includes at least one of a brightness enhancing film and a second light diffusing film.

14. The light bar system of claim 13, wherein the additional light altering film is a brightness enhancing film,

wherein the brightness enhancing film is disposed adjacent the light diffusing layer and spaced apart from the light source.

15. The light bar system of claim 14, further comprising:

an outer lens, an outer surface of the outer lens facing a driver and an inner surface of the outer lens adjacent the outer surface of the light diffusing layer such that the light diffusing layer is between the brightness enhancing film and the outer lens.

16. The light bar system of claim 9, further comprising:

a second light diffusing layer located adjacent the light source such that the air gap is defined between the light diffusing layer and the second light diffusing layer.

17. A light bar system for a steering wheel comprising:

at least one light source disposed adjacent a portion of an armature of the steering wheel;

a lens having an outer surface facing a driver and an inner surface facing the light source;

wherein light is directed towards the driver as it passes through the lens from the inner surface to the outer surface, such that the light exiting the outer surface appears as a continuous stream of light across the outer surface of the lens.

18. The light bar system of claim 17, wherein the lens diffuses ambient light that enters the lens and is reflected from a surface of the light bar system prior to the reflected ambient light being emitted through the lens toward the driver.

19. The light bar system of claim 17, further comprising an inner lens located between the lens and the light source, where an outer surface of the inner lens faces the lens and an inner surface of the inner lens faces the light source.

20. The light bar system of claim 19, wherein at least one of the lens and the inner lens include at least one of a filler and a fiber to increase a brightness of the light output the lens.
