Indicator device with a lighted pointer

1. An indicator device, comprising:

a dial having a pointer movable thereover, the pointer being provided with an inlet portion for receiving a light beam produced by at least one lighting member and an outlet portion, wherein the lighting member is positioned to emit the light beam towards the dial;

wherein the dial is arranged to form a member for guiding the light beam towards the inlet portion of the pointer;

wherein the dial has an aperture defined by an inner edge of the dial;

wherein the inlet portion of the pointer extends towards the aperture;

wherein the inner edge of the dial forms the outlet face for the light beam; and

wherein the inlet portion of the pointer extending towards the aperture receives the light beam there through and faces the inner edge.

2. The indicator device of claim 1 , wherein an inlet face of the dial is mounted perpendicular to the light beam, and the dial includes at least one reflector face for reflecting the light beam received from the inlet face towards the outlet face.

3. The indicator device of claim 2 , wherein the at least one reflector face is covered in a reflective coating extending over a corresponding portion of the dial.

4. The indicator device of claim 2 , wherein the inlet portion of the pointer is perpendicular to a travel plane defined by the pointer, and wherein the outlet portion of the pointer is substantially parallel to the travel plane.

5. The indicator device of claim 4 , wherein the pointer is mounted to follow a curved path and the outlet face of the dial extends parallel to the curved path in such a manner that the inlet portion of the pointer constantly faces towards the outlet face of the dial while traveling along the curved path.

6. The indicator device of claim 5 , wherein the inlet face and the reflector face of the dial are adjacent to an outer edge of the dial.

7. A vehicle instrument cluster including any number of indicators, comprising:

a housing at least partially covering the indicator;

a light source mounted with respect to the housing;

a ring-shaped dial coupled to the housing, configured to guide light from the light source to a pointer, wherein an inner edge of the dial, which defines an aperture, provides an outlet face for the light guided to the pointer, wherein the aperture is configured to receive the pointer such that light from the outlet face can enter a portion of the pointer in the aperture; and

wherein the pointer is coupled to the housing and configured to rotate with respect to the housing and further configured to selectively guide light from the dial to illuminate a portion of the instrument cluster.

8. The instrument cluster of claim 7 , further comprising:

a display coupled to the housing;

an arm coupled to the pointer; and

an electric motor coupled to the housing on a first side of the display and configured to rotate the arm with respect to the housing;

wherein the pointer is configured to rotate on a second side of the display.

9. The instrument cluster of claim 8 , wherein the display is a liquid crystal display.

10. The instrument cluster of claim 7 , wherein the display shows hash marks, the dial configured to enable the hash marks to show there through.

11. The instrument cluster of claim 7 , wherein the pointer includes at least one reflective surface to guide light there through.

12. The instrument cluster of claim 11 , wherein the dial further includes at least one reflective surface to guide light there through.

13. The instrument cluster of claim 7 , wherein the pointer includes an indicator portion, configured to receive light from at least one reflective surface and guide light there through.

14. The instrument cluster of claim 7 , wherein the pointer includes an arm extending from an axis of rotation of the pointer, and a light guide extending from the arm, and wherein the arm is hidden from view and the light guide receives light from the dial.

15. The instrument cluster of claim 7 , wherein the pointer is transparent.

16. The instrument cluster of claim 7 , wherein the light source is a light emitting diode.

17. The instrument cluster of claim 7 , further comprising:

at least two light sources included in the housing, configured to selectively provide light to the pointer through the dial.

18. The instrument cluster of claim 7 , wherein the dial further includes at least one reflective surface to guide light there through.

19. The instrument cluster of claim 7 , wherein the dial has a semi-annular configuration and defines an inner portion and an outer portion, wherein the pointer rotates along the inner portion of the dial.

20. The instrument cluster of claim 7 , wherein the dial is made of a transparent material.

21. A ring-shaped dial for use in a vehicle instrument cluster, comprising:

a receiving portion configured to accept light therein;

at least one reflective surface included in the receiving portion to guide light received from a first direction and guide the light into a second direction; and

an inner edge of the dial, which defines an aperture and provides an outlet face for the light guided in the second direction;

wherein the aperture is configured to receive a pointer such that light from the outlet face can enter a portion of the pointer in the aperture.

22. The dial of claim 21 , wherein the dial is made of a transparent material.

23. A method of operating an indicator, configured for use in a vehicle instrument cluster, comprising:

providing at least one light source configured to provide light in a first direction;

providing a ring-shaped dial having

a reflective surface, configured to receive light from the first direction and guide light into a second direction, and

an inner edge of the dial, which defines an aperture and provides an outlet face for the light guided in the second direction;

providing a pointer, configured to receive light from the second direction and guide the light onto at least one portion of the instrument cluster, wherein the aperture is configured to receive the pointer such that light from the outlet face can enter a portion of the pointer in the aperture; and

rotating the pointer with respect to the dial to selectively illuminate the at least one portion of the instrument cluster, wherein the at least one portion of the instrument cluster is only illuminable by the light source when the pointer guides light there to.
