Abstract
The invention relates to an individual lighting device (20) for a vehicle seat including: a plurality of light sources (S1, S2, S3) having an adjustable light intensity and each emitting in a favored direction (D1, D2, D3), at least two sources being arranged so that the directions (D1, D2, D3) of those two sources are not parallel.
Claims20
An individual lighting device for a vehicle seat comprising:
- a plurality of light sources, each having a light intensity that is adjustable among at least three values and each emitting in a favored direction,
- at least two of the plurality of light sources being arranged so that the directions of the at least two light sources are not parallel.
An individual lighting device for a vehicle seat comprising:
- three separate light sources attached to a vehicle seat, each of the three light sources emitting in a favored direction that is not parallel to the favored direction of any other of the three light sources;
- and
- a controller that varies light intensity of each of the three light sources separately and among at least three intensities including a minimum intensity, a maximum intensity, and an intermediate intensity between the minimum and maximum intensity,
- wherein the three light sources are arranged so that a first area of the seat receives light emitted from all three of the light sources, so that a second area of the seat receives light emitted from only two of the three light sources, and so that a third area of the seat receives light emitted from only one of the three light sources.
