Abstract
The invention proposes a device and a method which make it possible to manage the light fluxes emitted respectively by fixed and mobile parts of a light device for a motor vehicle. It is noteworthy that the management of the light fluxes takes into account the relative position between the different parts of the light device.
Claims20
A light device for a motor vehicle, comprising at least two light sources, of which at least one first source is intended to be arranged on a first part of the chassis of the motor vehicle, and at least one second source is intended to be arranged on a second part of the chassis, such that the first and the second sources are capable of assuming at least two distinct and predetermined relative positions (P, P′) relative to one another,
- wherein the device comprises means for controlling the light flux from the light sources, configured to control the emission of different light fluxes by the light sources, according to the relative position of the first and of the second sources, and
- wherein the control means are configured to control the two light sources according to the relative position of the first and of the second sources such that, for at least one first predetermined relative position, the first light source participates in the production of a first predetermined regulatory light function of the motor vehicle and the second light source participates in the production of a second predetermined regulatory light function of the motor vehicle distinct from the first predetermined regulatory light function and such that, for at least one second predetermined relative position, the first light source participates in the production of the second predetermined regulatory light function.
A method for managing the light flux in a light device for a motor vehicle, wherein the method comprises the following steps:
- providing a light device comprising at least two light sources, of which at least one first source is intended to be arranged on a first part of the chassis of the motor vehicle, and at least one second source is intended to be arranged on a second part of the chassis, such that the first and second sources are capable of assuming at least two distinct and predetermined relative positions relative to one another;
- obtaining a signal indicative of the relative position of the first and second sources using means capable of obtaining such a signal;
- controlling the two light sources such that, according to the relative position of the first and second sources such that, for at least one first predetermined relative position, the first light source participates in the production of a first predetermined regulatory light function of the motor vehicle and the second light source participates in the production of a second predetermined regulatory light function of the motor vehicle distinct from the first predetermined regulatory light function and such that, for at least one second predetermined relative position, the first light source participates in the production of the second predetermined regulatory light function, the position being indicated by said signal;
- powering at least one of the light sources so as to emit different light fluxes according to the relative position of the first and second sources, the position being indicated by said signal.
