A series of orifices 4 is configured so that the chamber 5 of the box 2 communicates with the exterior of the closed housing 15 (Figure 5).
    A medium which communicates with another medium means that there can be an exchange of fluid such as water vapor between the two mediums.
    In one embodiment, the device 1 also comprises a moisture absorber 6 arranged in the chamber 5 of the box 2. The moisture absorber 6 is able to absorb the moisture present in the chamber 5 of the box 2 (figure 5). For example, the moisture absorber 6 includes silica gel.

    Furthermore, the device 1 comprises a heating element 9 configured to emit heat when the actuation module 8 is activated.
    According to one embodiment (FIGS. 7 to 14), the device comprises at least a second flap 18 configured for, alternatively:
    open the second series of holes 4 when the first flap or flaps 7 close the first series of holes 3, or
    - close the second series of holes 4 when the first flap (s) 7 open the first series of holes 3.
    According to a preferred embodiment, the device 1 further comprises a box 19 defining a chamber 20. The box 19 is configured so that the chamber 20 communicates with the chamber 5 through the series of orifices
    4. The box 19 includes a series of holes 21 configured so that the chamber 19 communicates with the outside of the closed box 15.
    According to a first example (FIGS. 1 to 5), the actuation module 8 comprises:
    a closing sub-module configured to close the series of orifices 3 by the flap or flaps 7 when the actuation module 8 is activated, a return sub-module, such as a spring, configured to bring the or the flaps 7 to open the series of orifices 3 when the actuation module 8 is inactivated.
    In this first example, when the actuation module 8 is activated, the closing submodule exerts a force acting against the force exerted by the return submodule so that the flap or flaps 7 close the series of orifices 3 .
    According to a variant of the first example, the closing submodule of the actuation module 8 is also configured to open the series of orifices 4 by the flap or flaps 18 when said actuation module 8 is activated. In addition, the reminder sub-module is also configured to cause the flap or flaps 18 to close the second series of orifices 4 when said actuation module 8 is deactivated.
    According to a second example (FIGS. 7 to 10), the flap or flaps 7 comprise a plate 23 parallel to a plane containing the series of orifices 3. The plate 23 comprises at least one open part 24 and at least one sealing part 25. For example, the plate 23 corresponds to a solid plate comprising openings.

    In this second example, the actuation module 8 is configured to move the plate 23 parallel to the plane containing the series of orifices so that the plate 23 alternately occupies at least one or the other of the following positions:
    a first position in which the open part or parts 24 come into coincidence with the orifice (s) of the series of orifices 3 for opening the series of orifice orifices 3, or a second position in which the or the obturating part or parts 25 enter in coincidence with the orifice (s) of the series of orifices 3 to close the orifices of the series of orifices 3.
    In these two positions, the plate 23 remains pressed against the series of orifices 3.
    According to a variant of this second example, the flap or flaps 18 comprise a plate 26 parallel to a plane containing the series of orifices 4. Similarly to the first plate 23, the plate 26 comprises at least one open part 27 and at minus a sealing part 28.
    In this variant, the actuation module 8 also being configured to move the plate 26 parallel to the plane containing the series of orifices 4 so that the plate 26 alternately occupies at least one or the other of the following positions:
    a first position in which the open part (s) 27 come into coincidence with the orifice (s) of the series of orifices 4 to open the series orifice of orifices 4, when the plate 23 is in its second position, or a second position in which the obturating part or parts 28 come into coincidence with the orifice (s) of the series of orifices 4 to close the orifices of the series of orifices 4, when the plate 23 is in the first position.
    In these two positions, the plate 26 remains pressed against the series of orifices 4.
    As shown in Figures 7 to 10, the actuation module 8 can move the flap (s) 7 and / or the flap (s) 18 by rotation. The actuation module 8 can therefore comprise a motor having a motor shaft A perpendicular to the flap (s) 7 and 18 and capable of driving the plate 23 and / or the plate 26 in rotation about the axis of the motor shaft A or a shaft B parallel to the motor shaft A via a gear. Preferably, the motor is a direct current motor.
    According to a third example (FIGS. 11 to 14), the flap or flaps 7 comprise a sealing plate 29 parallel to a plane containing the series of orifices 3.
    In this third example, the actuating means 8 is configured to move the shutter plate 29 in translation along a normal of the plane containing the series of orifices 3 so that the shutter plate 29 occupies at least one or the other. of the following positions:
    - A first position in which the sealing plate 29 is pressed against the orifice or orifices of the series of orifices 3 to close the orifices of series of orifices 3, or a second position in which the obturating plate 29 is distant from the or orifices of series 3 of orifices to open the orifices of series of orifices 3.
    In a variant of the third example, the flap (s) 18 also comprise a sealing plate 30 parallel to a plane containing the series of orifices 4.
    In this variant, the actuating means 8 is also configured to move the shutter plate 30 in translation along a normal of the plane containing the series of orifices 4 so that the shutter plate 30 occupies at least one or the other of the following positions:
    a first position in which the obturating plate 30 is pressed against the orifice or orifices of the series of orifices 4 to close the orifices of series of orifices 4 when the obturating plate 29 is in its second position, or a second position in which the shutter plate 30 is remote against the orifice (s) of the series of orifices 4 to open the orifices of the series of orifices 4 when the shutter plate 29 is in its first position.
    As shown in FIG. 1 to 14, in this third example, the flap (s) 7 and / or the flap (s) 18 can be driven simultaneously by translation by the actuation module 8. The actuation module 8 can therefore comprise a motor having a motor shaft A parallel to (x) sealing plates 29 and 30 and capable of driving the plate 29 and / or the plate 30 in translation by means of a pinion gear P. Preferably, the motor is a motor direct current.
    Thus, when the flap or flaps 7 is open, the moisture 17 contained in the housing 15 of the projector 16 enters the box 2 of the device 1.
    For example, moisture can be absorbed by the moisture absorber
    6.
    For example, the heat emitted by the heating element 9 is capable of transforming the moisture absorbed by the humidity absorber 6 into water vapor 6. The water vapor 11 is then evacuated through the orifice 4 towards outside of box 2.
    According to one embodiment, the heating element 9 corresponds to a component of the actuation module 8 capable of heating when the actuation submodule is activated.
    The heating element 9 may include or correspond to a thermal resistance. The heating resistor is configured to operate in open circuit when it reaches a predetermined temperature.
    In another example, the heating element 9 includes an electromagnetic element. The electromagnetic element can be an electromagnet which allows the actuation module 8 to close the shutter 7 when said actuation module 8 is activated.
    The moisture absorber 6 may correspond to a component capable of absorbing moisture, such as silica gel. Said component can coat the inner surface of the box 2, but it can also be contained in an internal housing provided near the heating element 9. The silica can also be contained in or on an adhesive support capable of adhering to a surface contained in room 5.
    According to one embodiment (FIG. 2), the device 1 comprises a membrane 10 closing off the series of orifices 21. The membrane 10 is configured to allow the water vapor 11 present in the box to come out of the chamber 20
    2. The water vapor contained in the box 2 and which is evacuated by the series of orifice 21 may correspond to the humidity previously absorbed by the humidity absorber 6 which has been transformed into water vapor by the heat transmitted by the heating element 9 or to the humidity contained in the chambers 5, 20 but which has not been absorbed by the humidity absorber 6.
    The invention also relates to a vehicle headlight 16 comprising a housing 15 closed by a window 13 and housing at least one light source 14 (FIG. 6).
    The closed housing 15 comprises a wall 12 through which is fixed a device 1 as described above.
    The interior of the housing 15 then communicates with the chamber 5 of the first box 2 of said device 1 through the series of orifices 3 and the exterior of the housing 15 communicates with the chamber 5 of the first box 2 of said device 1 through the second series of holes 4.
