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.

Abstract: Methods and apparatus in which at least one first LED generates first radiation having a first spectrum, and at least one second LED generates second radiation having a second spectrum different than the first spectrum. One or more controllers control at least one of the first radiation and the second radiation so as to control at least a color temperature of visible radiation.

In various implementations, the sample radiation may be ambient illumination (e.g., natural-light and/or light from other light sources), may be the visible radiation itself (e.g., to provide feedback to the one or more controllers), or generally any desired lighting condition to simulate.
