- the invention proposes a new and inventive approach that makes it possible to solve at least in part the disadvantages of the prior art. More particularly, the invention makes it possible to provide a device that optimizes congestion because all the functions are fulfilled within the same device. In addition, such a device can be used in all conventional situations because the current lighting functions are fulfilled. Finally, such a solution is relatively simple from an architectural point of view.

- the second module may be able to emit a light beam with a cutout in accordance with the ECE R112 regulation, or it may be able to emit a light beam with a break according to the ECE R123 Type C regulation.
- the device further comprises vertical adjustment means of the light beam emitted by each of the three modules
- each of said first, second and third optical systems may comprise at least one element among which:
- the invention also relates to a method for controlling a vehicle lighting device capable of emitting at least one light beam, said device having:
- a projector comprising a first module, a second module, and a third module
- control unit able to control the power supply of each of the three modules independently, said method comprising the following successive steps:
- the step of supplying electricity comprises a step of chopping the electricity supplied.
- the invention also relates to a motor vehicle comprising at least one lighting device according to one of the aforementioned embodiments.
- FIG. 1 is a perspective view of a device according to an embodiment of
- FIG. 2 is an exploded perspective view of a device according to the embodiment of FIG. 1;
- FIG. 3 is a truth table showing the ignition power of each of the modules according to the selected function.
- the vehicle lighting device which is, in this example, a left-side lighting device, has a projector 1 for emitting a light beam towards the outside.
- This projector 1 comprises several modules. More particularly, the projector 1 comprises a first module 10, a second module 11, and a third module 12. Each of these first 10, second 11 and third 12 modules comprises an optical system 100, 110, 120, a radiator 101, 111, 121, an electronic card 102, 112, 122 comprising a light source and control means the light source related to the respective electronic board.
- the light source is preferably an LED source (international acronym for Electro Luminescent Diode) which also allows to save energy and implement reliable light sources with a long life. life. More particularly, these LEDs can be of the mono-chip or multi-chip type, for example bi-chip, that is to say LEDs incorporating one or more chips capable of emitting light.
- the first 100, second 110 and third 120 optical systems comprise one or more elements among which:
- the various modules 10, 11, 12 have respective architectures designed to obtain light distributions in accordance with the requirements and regulations with respect to photometry, this distribution being able to be modulated by the means of respective steering of the modules.
- the first module 10 is designed to emit a beam of light having a flat cutoff, that is to say to have a distribution of light with a flat cut (horizontal cut-off in English).
- the flat cut is a common concept in the technical field considered as it is for example the case in United Nations approval ECE324 when it states that a flat cut must be a sufficiently fine horizontal straight line produced by a light beam to allow a satisfactory fit.
- the second module 11 is for its part capable of emitting a light beam with a cutoff that may be in accordance with the ECE R112 regulation or the ECE R123 type C regulation according to the functions requested by the user.
- the third module 12 is designed to create an uninterrupted beam of light compatible with the regulatory requirements of a Route type beam.
- the device comprises a control unit able to control the power supply of each of the three modules 10, 11, 12, independently for each of these modules.
- This control unit has means for adjusting the voltage sent to each of the control means 102, 112, 122 so as to vary the light intensity of the LEDs and therefore the strength of the light beam of the projector 1.
- It also comprises voltage chopping means sent to each of the driving means so that below a predefined percentage of luminous intensity, the chopping means causes the LED to jiggle due to a chopping of the voltage, this clangling not being noticeable to a user.
- the control unit will adapt the current passing through the LEDs via the means for adjusting the voltage.
- the control unit after having reduced the current to a level of 10% of light intensity, will perform a chopping of the voltage by the hash means. This hash being done at a sufficiently high frequency (greater than 200 Hz in this example) by generating a switching on and off of the LED, the blinking is not perceptible by a user and results in a drop in light intensity of the LED.
- the device further comprises means for vertical adjustment of the light beam emitted by each of the three modules. These adjustment means thus make it possible to modify the direction of the beam of light emitted by the projector.
- the projector presented in this embodiment is designed, through the three modules of which it is composed, to perform eight main functions:
- the "tourist crossing" function is achieved by a 100% ignition power of the first module 10 and an ignition power of 0% of the second 11 and third 12 modules.
- the vertical adjustment of the modules is nominal to perform this function.
- the "standard crossing" function is achieved by a 100% ignition power of the first 10 and second 11 modules and a 0% ignition power of the third module 12.
- the vertical adjustment of the modules is nominal to achieve this. function.
- the "city crossover" function is achieved by a 100% ignition power of the first module 10, an ignition power of 80% of the second module 11, and an ignition power of 0% of the third module.
- the vertical adjustment of the modules is 0.3% lower than nominal to achieve this function.
- the "motorway crossing" function is achieved by a 100% ignition power of the first module 10, a 120% ignition power of the second module 11, and a 0% ignition power of the third module 12. vertical adjustment of the modules is raised by 0.6% compared to nominal to achieve this function.
- the "fog" function is achieved by an ignition power of 80% of the first module 10 and an ignition power of 0% of the second 11 and third 12 modules.
- the vertical adjustment of the modules has decreased by 1% to achieve this function.
- the "road" function is achieved by a 100% ignition power of the first 10, second 11 and third 12 modules.
- the vertical adjustment of the modules is nominal to perform this function.
- the "daytime running" function is performed by a 0% ignition power of the second module 11 for an ignition power of 2% of the first 10 and third 12 modules.
- the vertical adjustment of the modules is nominal to perform this function.
- the "lanterns" function it is achieved by a 0% ignition power of the second module 11 and an ignition power of 0.2% of the first 10 and third 12 modules.
- the vertical adjustment of the modules is nominal to perform this function.
- the "fog" function is described in the ECE regulation R19 by lowering the beam 1 ⁇ 6 through the adjustment means and turning on the first module 10 at an ignition power of 80%.
- this projector fits perfectly to motor vehicles, in the form of a left projector and a straight projector, located at the front of the vehicle.
- these projectors are placed on other types of motorized vehicles such as a truck, a motorcycle, a quad, a bus ...
- An adaptation of the light distribution of optical systems would be to do so to meet the regulations inherent in these non-automotive vehicles.
