1. A vehicle illumination system, comprising:
- a light source configured for emitting light in the visible wavelength range for illuminating surroundings of a vehicle, an interior of the vehicle, or both the surroundings and the interior;
a modulation unit configured for modulating the emitting of the light of the light source, where the emitted light is modulated with a frequency that is high enough so that the modulation of the light is substantially not perceivable by a person;
a sensor that detects modulated light emitted by the light source and provides a received signal indicative thereof;
a vehicle range finding system that receives and processes the received signal and generates a distance signal relating to the distance of the object; and
a vehicle information transfer system that includes an information processing unit, which receives and processes the received signal and controls the modulation of the light in such a way that the emitted light is modulated in dependence on a predetermined information to be transmitted.

Abstract
A vehicle illumination system includes a light source emitting light for illuminating the vehicle surroundings or the vehicle interior or both, and a modulation unit modulating the emitting of light of the light source, where the emitted light is modulated with a frequency that is high enough so that the modulation of the light is substantially not perceivable by a person.

18. A method for illuminating a vehicle, comprising:
-
illuminating surroundings of the vehicle, an interior of the vehicle, or both the surroundings and the interior, with light in the visible wavelength range emitted by a light source; and modulating the emitting of the light by utilizing a modulation unit, where the emitted light is modulated with a frequency which is high enough so that the modulation of the light is substantially not perceivable by a person, and controlling the modulation of light by utilizing an information processing unit in such a way that the emitted light is modulated in dependence on a predetermined information to send the information; detecting with a sensor the modulated light emitted by the light source and reflected by an object, where the sensor generates a distance signal relating to the distance of the object; and detecting with the sensor modulated light emitted by a vehicle illumination system disposed in another vehicle by utilizing a detector that generates a light signal in response to detecting the modulated light, and processing the light signal using the information processing unit to obtain a received information. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
