Abstract

A light bar is provided and includes an elongated carrier having a surface extending along the carrier. Capacitive sensors are spaced along the carrier and positioned below the surface. Light sources are included for illuminating the surface, each associated with at least one capacitive sensor and positioned proximate thereto. A controller is included for detecting capacitive changes in the capacitive sensors, wherein when the controller detects a capacitive change in a capacitive sensor, the controller alters an illumination state of a light source associated therewith.

First claim

What is claimed is:

1. A light bar of a vehicle, comprising:
an elongated carrier integrated in an outer surface of a vehicle fixture and having a surface extending a length of the carrier, the vehicle fixture located inside the vehicle and the outer surface being directly exposed within an occupant compartment of the vehicle;
capacitive sensors spaced along the carrier and positioned below the surface;
light sources for illuminating the surface, each associated with at least one capacitive sensor and positioned proximate thereto, wherein every other light source is enclosed by one of the capacitive sensors and the remaining lights sources are free from being enclosed by capacitive sensors; and
a controller for detecting capacitive changes in the capacitive sensors, wherein when the controller detects a capacitive change in a capacitive sensor, the controller alters an illumination state of the light source enclosed by the capacitive sensor and at least one other light source adjacent thereto;
wherein when a light source is in an activated state, each subsequent capacitive change in the associated capacitive sensor results in an incremental increase in brightness of the light source until a maximum brightness is reached; and
wherein when the maximum brightness is reached, each subsequent capacitive change in the associated capacitive sensor results in an incremental decrease in brightness of the light source until the light source becomes deactivated, and
wherein when the light source is activated at a lowest brightness setting, the light source illuminates in a first color, and wherein when the light source is activated at a maximum brightness setting, the light source illuminates in a second color that is perceptively different than the first color.

2. The light bar of claim 1 , wherein the capacitive sensors have a round configuration and an opening extending therethrough for enclosing the corresponding light source.

3. The light bar of claim 1 , wherein each light source comprises at least one of a red light emitting diode, a green light emitting diode, a blue light emitting diode, and a white light emitting diode.

4. The light bar of claim 1 , wherein the controller alters the illumination state of the light source by at least one of activating the light source, deactivating the light source, changing a color expressed by the light source, and adjusting a brightness of the light source.

5. The light bar of claim 1 , installed in a vehicle fixture and configured for use in a vehicle lighting system, wherein the controller is supplied input from at least one of an input device and a vehicle equipment.

6. A light bar of a vehicle, comprising:
a carrier having a surface and integrated with an outer surface of a vehicle fixture located inside the vehicle, the outer surface being directly exposed within an occupant compartment of the vehicle;
capacitive sensors spaced along the carrier;
light sources for illuminating the surface, wherein every other light source is enclosed by a capacitive sensor and the remaining light sources are free from being enclosed by capacitive sensors; and
a controller for detecting capacitive changes in the capacitive sensors, wherein when the controller detects a capacitive change in a capacitive sensor, the controller alters an illumination state of at least a light source enclosed by the capacitive sensor;
wherein when the light source is activated at a lowest brightness setting, the light source illuminates in a first color; and
wherein when the light source is activated at a maximum brightness setting, the light source illuminates in a second color that is perceptively different than the first color, and
wherein when the light source is in an activated state, each subsequent capacitive change in the associated capacitive sensor results in an incremental increase in brightness of the light source until a maximum brightness is reached; and wherein when the maximum brightness is reached, each subsequent capacitive change in the associated capacitive sensor results in an incremental decrease in brightness of the light source until the light source becomes deactivated.

7. The light bar of claim 6 , wherein the capacitive sensors have a round configuration and an opening extending therethrough for enclosing the corresponding light source.

8. The light bar of claim 6 , wherein each light source comprises at least one of a red light emitting diode, a green light emitting diode, a blue light emitting diode, and a white light emitting diode.

9. The light bar of claim 6 , further comprising indicia disposed to indicate a relative location of at least one of the capacitive sensors.

10. The light bar of claim 6 , wherein the controller alters the illumination state of the light source by at least one of activating the light source, deactivating the light source, changing a color expressed by the light source, and adjusting a brightness of the light source.

11. The light bar of claim 6 , configured for use in a vehicle lighting system, wherein the controller is supplied input from at least one of an input device and a vehicle equipment.

12. A vehicle light bar comprising:
capacitive sensors;
light sources spaced along a carrier integrated with an outer surface of an interior vehicle fixture, the outer surface being directly exposed within an occupant compartment of the vehicle, and every other light source enclosed by one of the capacitive sensors and the remaining lights sources free from being enclosed by capacitive sensors; and
a controller for detecting capacitive changes in a capacitive sensor and altering an illumination state of at least the light source enclosed by the capacitive sensor when a capacitive change is detected, and
wherein when the light source is activated at a lowest brightness setting, the at least one light source illuminates in a first color, and wherein when the at least one light source is activated at a maximum brightness setting, the at least one light source illuminates in a second color that is perceptively different than the first color.

13. The light bar of claim 12 , wherein each light source is associated with at least one capacitive sensor such that when the at least one capacitive sensor undergoes a capacitive change, the controller alters the illumination state of any light sources associated with the at least one capacitive sensor.

14. The light bar of claim 12 , wherein the capacitive sensors have a round configuration and an opening extending therethrough for enclosing the corresponding light source.

15. The light bar of claim 12 , wherein each light source comprises at least one of a red light emitting diode, a green light emitting diode, a blue light emitting diode, and a white light emitting diode.

16. The light bar of claim 12 , further comprising indicia disposed to indicate a relative location of at least one of the capacitive sensors.

17. The light bar of claim 12 , wherein the controller alters the illumination state of the light source by at least one of activating the light source, deactivating the light source, changing a color expressed by the light source, and adjusting a brightness of the light source.
