Abstract

Various implementations include a light bar system for a steering wheel of a vehicle that includes a high intensity light source, a light diffusing layer, and an outer lens. For example, in certain implementations, the light diffusing layer is disposed between a plurality of high intensity light emitting diodes (LEDs) and an outer lens, and the light diffusing layer causes the light from the LEDs to appear as a continuous stream of light across a length of the lens and provides sufficiently bright lighting to warn or communicate with the driver in various ambient lighting conditions. In certain implementations, the outer lens is colored to blend in with the rest of the steering wheel when the LEDs are not activated.

First claim

The invention claimed is:

1. A light bar system for a steering wheel comprising:
a light source disposed adjacent a portion of an armature of a steering wheel;
an outer lens;
a carrier defining a channel extending from the light source towards the outer lens, the channel comprising a proximal portion adjacent a proximal end of the channel, a distal portion adjacent a distal end of the channel, and a central portion disposed between the proximal and distal portions, the proximal and distal portions each have a substantially rectangular cross section as taken through a plane that is perpendicular to a front and rear surface of the steering wheel armature and a direction of rotation of the steering wheel, and the central portion has a substantially trapezoidal shaped cross section, and a width of the proximal portion is different than a width of the distal portion; and
a light diffusing layer disposed between the light source and the outer lens, the light diffusing layer being configured for diffusing light as it passes therethrough.

2. The light bar system of claim 1 , wherein the light diffusing layer is configured to cause the light being diffused there through to appear as a continuous stream of light across the light diffusing layer.

3. The light bar system of claim 1 , wherein the light diffusing layer comprises a light diffusing film.

4. The light bar system of claim 1 , wherein the light source comprises a light emitting diode (LED), wherein the light source comprises at least one visible light LED and at least one infrared light LED.

5. The light bar system of claim 4 , wherein the light bar system further comprises a printed circuit board (PCB) on which the at least one visible light LED and the at least one infrared light LED are disposed.

6. The light bar system of claim 1 , further comprising:
a printed circuit board (PCB) on which the light source is disposed; and
a housing including: a base disposed adjacent the armature of the steering wheel, and two opposing side walls extending from the base toward a front surface of the steering wheel to form a substantially U-shaped channel, an outer surface of each of the side walls forming an arcuate shape to follow an outer contour of the front surface of the steering wheel, wherein the carrier and the PCB are disposed within the U-shaped channel of the housing such that the PCB is disposed between the base of the housing and the proximal end of the carrier.

7. The light bar system of claim 6 , wherein the carrier comprises two opposing side walls, wherein a channel is formed between corresponding side walls of the carrier and the housing, wherein the light bar system further comprises an outer skin for covering the steering wheel, wherein edges of the outer skin are disposed within the channels formed between the corresponding side walls of the carrier and the housing.

8. A light bar system for a steering wheel comprising:
at least one light source disposed adjacent a portion of an armature of a steering wheel;
an outer lens;
a carrier defining a channel, the channel having a proximal end disposed adjacent the light source;
a light diffusing layer having an inner surface and an outer surface, the outer surface of the light diffusing layer being disposed adjacent the outer lens, the inner surface of the light diffusing layer being disposed adjacent the at least one light source, and the light diffusing layer being configured for diffusing light as it passes therethrough from the inner surface to the outer surface;
a printed circuit board (PCB) on which the light source is disposed; and
a housing including: a base disposed adjacent the armature of the steering wheel, and two opposing side walls extending from the base toward a front surface of the steering wheel to form a substantially U-shaped channel, an outer surface of each of the side walls forming an arcuate shape to follow an outer contour of the front surface of the steering wheel, wherein the carrier and the PCB are disposed within the U-shaped channel of the housing such that the PCB is disposed between the base of the housing and the proximal end of the carrier.

9. The light bar system of claim 8 , wherein the light diffusing layer is configured to cause the light being diffused there through to appear as a continuous stream of light across the light diffusing layer.

10. The light bar system of claim 8 , wherein the light diffusing layer comprises a light diffusing film.

11. The light bar system of claim 8 , wherein the light source comprises a light emitting diode (LED), wherein the light source comprises at least one visible light LED and at least one infrared light LED.

12. The light bar system of claim 11 , wherein the light bar system further comprises a printed circuit board (PCB) on which the at least one visible light LED and the at least one infrared light LED are disposed.

13. The light bar system of claim 8 , wherein the carrier comprises two opposing side walls, wherein a channel is formed between corresponding side walls of the carrier and the housing, wherein the light bar system further comprises an outer skin for covering the steering wheel, wherein edges of the outer skin are disposed within the channels formed between the corresponding side walls of the carrier and the housing.

14. A light bar system for a steering wheel comprising:
at least one light source disposed adjacent a portion of an armature of a steering wheel, the light source comprising at least one light emitting diode (LED);
