Abstract: The invention relates to a light system. The light system includes an emitting module that includes a light module capable of emitting a light beam that produces a flashing photometric function and a modulation unit arranged to modulate the emitted light beam on the basis of a modulating data sequence, a receiving module capable of receiving a light beam, and a computing unit arranged to generate modulating data sequences having different duty cycles in order to emit different modulated light beams during each active and inactive phase. The computing unit being arranged to determine a time of flight separating the emission of the first or of the second emitted modulated light beam from the reception of a light beam received by the receiving module.

Abstract: A method for limiting current in-rush in automotive lighting devices. By controlling the state of a switching circuit that is used to selectively connect a power supply to an automotive lighting device, the invention allows for selectively limiting the intensity of the current that is supplied to the lighting device. In accordance with preferred embodiments, this advantage is achieved by relying on electronic components that are nowadays used for different purposes.
