Abstract

A lighting system and method for a vehicle interior wherein the light system includes an electronic control unit (ECU) and a lighting layer having a plurality of light elements and a proximity sensing system. The lighting layer is coupled to the ECU and each of at least some of the light elements may be independently turned ON or OFF in response to a first proximity pattern provided by human interaction and received by the proximity sensing system. The lighting arrangement permits an occupant of the vehicle to selectively define the area and/or shape of local illumination and to control one or more characteristics of the illumination such as color or brightness.

Claims

1. A lighting system for a vehicle interior, comprising:

an electronic control unit (ECU); and

a lighting layer having a plurality of light elements and a proximity sensing system, wherein the lighting layer is coupled to the ECU,

wherein each of at least some of the light elements may be independently turned ON or OFF in response to a first proximity pattern provided by human interaction and received by the proximity sensing system.

2. The lighting system of claim 1 wherein lighting characteristics of the light elements are configurable in response to a second proximity pattern.

3. The lighting system of claim 2 wherein the first proximity pattern is the same as the second proximity pattern.

4. The lighting system of claim 2 wherein the characteristics include brightness and color.

5. The lighting system of claim 1 wherein the proximity sensing system is responsive to contact of human skin.

6. The lighting system of claim 1 wherein the one or more light elements are grouped into at least one sector, wherein the first proximity pattern illuminates all the light elements within the at least one lighting sector when any portion of the proximity pattern includes a proximity input to the at least one lighting sector.

7. The lighting system of claim 1 wherein the lighting layer is configurable to enable a user to define a lighting sector, wherein the lighting sector includes a plurality of the light elements.

8. The lighting system of claim 1 wherein the first proximity pattern defines an at least partially closed path, wherein a plurality of light elements bounded by the path is illuminated when the light elements on the path are illuminated.

9. A method of illuminating the interior of a vehicle, comprising the steps of:

detecting a first proximity input at a lighting layer of a vehicle having a proximity sensing system; and

illuminating at least a portion of the lighting layer based on the first input,

wherein the lighting layer comprises a plurality light elements that may be independently actuated.

10. The method of claim 9, wherein the portion of the lighting layer includes a plurality of light elements grouped in at least one of a pre-configured sector or a user-defined sector.

11. The method of claim 10, wherein the user-defined sector includes one of a closed path or a partially closed path defined by the first input, wherein the light elements located on the closed or partially closed path are illuminated.

12. The method of claim 11 further comprising the step of automatically illuminating the light elements bounded by the closed path.

13. The method of claim 11 further comprising the step of automatically closing the partially closed path by illuminating light elements and automatically illuminating the light elements bounded by the newly closed path.

14. The method of claim 9 further comprising detecting a second proximity input at the lighting layer and altering at least one characteristic of the emitted light based on the second input, wherein the at least one characteristic includes brightness and color.

15. The method of claim 14, wherein the second input is received at a portion of the light elements of an illuminated sector, wherein the at least one characteristic is automatically altered for the entire sector.
