| Title: |
Vehicle Lighting Methods and Apparatus |
| Abstract: |
Vehicle lighting methods and apparatus, in which an LED-based light source
is configured to generate at least visible radiation associated with a
vehicle. The light source is controlled such that the generated visible
radiation has a variable color over a range of colors including at least
three different perceivable colors. Examples of vehicles in which such
methods and apparatus may be used include, but are not limited to, an
automobile, airplane, boat, non-motorized vehicle, etc. The LED-based
light source may be disposed inside the vehicle (e.g., dashboard,
instrument panel) or outside the vehicle (e.g., brake lights,
undercarriage lighting), and may be controlled to generate white light as
one of the perceivable colors. A user interface may be employed to
facilitate an adjustment of the variable color of the generated visible
radiation. Additionally, information relating to at least one condition
associated with the vehicle may be employed to control the LED-based
light source such that the variable color of the generated visible
radiation is based at least in part on the condition associated with the
vehicle.
