Abstract

An enhanced color messaging instrument gauge assembly is disclosed having a lens with one or more surface interruptions. A lens covering an instrument cluster transmits colored light longitudinally from at least one light source near its edge. Light encountering the surface interruption causes the surface interruption to illuminate. In one embodiment, different colored light can be coordinated with activation of symbols on the instrument cluster to attract the attention of an operator to an abnormal operating condition or to reinforce other information being communicated to the operator on the instrument cluster.

Claims

1. An instrument gauge assembly of a type having an instrument cluster comprising indicators and visible symbols and in communication with a controller, said instrument gauge assembly comprising:

a lens covering at least a portion of the instrument cluster and capable of carrying light longitudinally from its edge,

a light source in communication with the controller,

a light pickup formed on the lens and having an edge portion proximate to the light source, and

an interruption on a surface of the lens which illuminates with light transmitted within the lens by the light source, wherein the interruption on the surface of the lens is in the perimeter region of the lens which is visible to an operator.

2. The assembly of claim 1, wherein the light transmitted by the light source is colored.

3. The assembly of claim 2, further comprising an abnormal operating condition signal communicated by the controller, wherein the light source illuminates the surface interruption in response to the abnormal operating condition signal.

4. The assembly claim 3, wherein the controller is programmed to cause the light source to intensify or blink as an abnormal operating condition persists or becomes more urgent.

5. The assembly of claim 1, wherein the lens is made of plastic.

6. The assembly of claim 1, comprising a plurality of light sources and a plurality of light pickups.

7. The assembly of claim 1, wherein the surface interruption is etched or molded into the lens.

8. The assembly of claim 1, wherein the surface interruption comprises a material applied onto the lens.

9. The assembly of claim 1, wherein the light source is an LED.

10. The assembly of claim 1, wherein the lens covers substantially the entire instrument cluster.

11. The assembly of claim 1, wherein the surface interruption is configured to produce a clear and distinct line or pattern of illumination.

12. The assembly of claim 1, wherein the surface interruption is configured to produce a diffused area of illumination.

13. An instrument gauge assembly of a type having an instrument cluster comprising indicators and visible symbols and in communication with a controller, said instrument gauge assembly comprising:

a lens covering at least a portion of the instrument cluster and capable of carrying light longitudinally from its edge,

a plurality of light sources in communication with the controller,

a plurality of light pickups formed on the lens, each of the light pickups having an edge portion proximate to at least one of the light sources, wherein at least one of the light pickups has an edge portion proximate to more than one of the light sources whereby light is first received by the at least one light pickup from the more than one light sources, the more than one light sources being capable of emitting different colored light, and

an interruption on a surface of the lens which illuminates with light transmitted within the lens by the light source.

14. The assembly of claim 13, further comprising a first portion of the lens having a first surface interruption zone associated with a first light color and a second portion of the lens having a second surface interruption zone associated with a second light color.

15. The assembly of claim 13, wherein at least one of the plurality of more than one light sources is itself configured to emit a plurality of colors.

16. The assembly of claim 13, wherein an operator can select at least one illumination color or color sequence from the plurality of light sources.

17. An instrument gauge assembly of a type having an instrument cluster comprising indicators and visible symbols and in communication with a controller, said instrument gauge assembly comprising:

a lens covering at least a portion of the instrument cluster and capable of carrying light longitudinally from its edge,

a light source in communication with the controller,

a light pickup formed on the lens and having an edge portion proximate to the light source, and

an interruption on a surface of the lens which illuminates with light transmitted within the lens by the light source; and

an operator switch in communication with the controller and configured to modify or disable the illumination of the surface interruption.
