    LIGHT MODULE COMPRISING AT LEAST ONE REMOVABLE LIGHT SOURCE
    TECHNICAL FIELD OF THE INVENTION
    The present invention relates to a light module for a motor vehicle.
    It finds a particular but non-limiting application in lighting devices 5, such as motor vehicle headlights.
    TECHNOLOGICAL BACKGROUND OF THE INVENTION
    A light module for a motor vehicle comprises, in a manner known to a person skilled in the art:
    - optical means;
    - a support for the optical means;
    - at least one light source housed in the light module.
    The light source includes:
    - means of light emission;
    - a mechanical support for the light emission means.
    The lifespan of a light source, such as a semiconductor emitting chip, is generally greater than 3000 hours of operation. In the event of a breakdown, the question of replacing this light source arises. In order to replace a defective light source, it is known to remove the entire light module, that is to say the optical means and the defective light source.
    A disadvantage of this state of the art is that the replacement of the entire light module leads to the disposal of elements, such as the optical means, elements which are not necessarily defective. It is therefore necessary for the operator to purchase a new complete light module each time a light source is defective, which makes it more expensive to replace the light module.
    In this context, the present invention aims to solve the aforementioned drawback.
    GENERAL DESCRIPTION OF THE INVENTION
    To this end, the invention proposes a light module for a motor vehicle, said light module comprising:
    - an optical means mounted fixed in the light module, said optical means comprising a base with a first housing;
    a support for the optical means mobile in translation relative to the optical means, said support for the optical means comprising a base with a second housing, said support for the optical means being adapted to take:
    - a locking position to maintain at least one light source partly in said first housing and partly in said second housing; and
    - an unlocking position for removing said at least one light source from the light module;
    said at least one light source being removable and comprising:
    - means of light emission;
    - a mechanical support for the light emission means.
    Thus, as will be seen in detail below, the removable light source is placed in a housing formed in part of a first housing belonging to the optical means and in part of a second housing belonging to the support of the optical means. The support of the optical means is movable in translation relative to the optical means between a locking position and an unlocking position. In the unlocked position, the light source is accessible by an operator and it is then possible to remove the defective light source from the light module. Only the light source is then replaced, which reduces the overall cost of this maintenance operation.
    According to non-limiting embodiments, the light module can also include one or more additional characteristics among the following:
    According to a nonlimiting embodiment, the support of the optical means is movable in translation according to:
    - a longitudinal direction; or

    - a counterpart belonging to the optical means;
    - A lug belonging to the support of the optical means adapted to cooperate with said counterpart;
    - at least one leaf spring belonging to the optical means adapted to hold the lug in the counterpart.

    - In the longitudinal direction at two primary reference points by means of two primary locking means of the base of the support of the optical means;
    - in the transverse direction at a secondary reference point by means of a secondary locking means.
    According to a nonlimiting embodiment, the two primary locking means and the secondary locking means are leaf springs.
    According to a nonlimiting embodiment, the light source is blocked in the first housing and the second housing when the support of the optical means is in the locked position following a translation in the transverse direction:
    - in the longitudinal direction at a primary reference point by means of a primary blocking means of the base of the optical means;
    - In the transverse direction at two secondary reference points by means of two secondary locking means of the base of the support of the optical means.

    DESCRIPTION OF EMBODIMENTS OF THE INVENTION
    Identical elements, by structure or by function, appearing in different figures keep, unless otherwise specified, the same references.
    The light module 10 for a motor vehicle according to the invention is described with reference to Figures 1 to 12.
    By motor vehicle is meant any type of motor vehicle.
    In a nonlimiting embodiment taken in the following description, the light module 10 belongs to a lighting and / or signaling device. In a nonlimiting variant, the lighting and / or signaling device is a motor vehicle headlamp.
    As illustrated in FIGS. 1 to 2, the light module 10 comprises:
    - An optical means 3 fixedly mounted in the light module 10. This optical means comprises a base 30 comprising a first housing 12A;
    a support 5 of the optical means 3 movable in translation relative to the optical means 3 according to:
    a longitudinal direction X or;
    a transverse direction Y perpendicular to the longitudinal direction X, or;
    - A diagonal direction having a component in the longitudinal direction X and a component in the transverse direction Y. This support 5 of the optical means 3 comprises a base 50 comprising a second housing 12B. The support 5 of the optical means 3 is adapted to take:
    - A locking position to maintain at least one light source 7 partly in the first housing 12A and partly in the second housing 12B; and
    - an unlocking position for removing the light source 7 from the light module 10.
    the light source 7 is removable and includes:
    - light emission means 11;
    - a mechanical support 13 of the light emission means 11.
    The light module 10 is adapted to emit light rays 4 forming a light beam. In a nonlimiting example, the light module 10 is adapted to provide a photometric function called "high beam" to produce a high beam. In another nonlimiting example, the light module 10 is adapted to provide a photometric function called "low beam" to produce, for example, a low beam.
    The various elements of the light module 10 are described in detail below.
    • Optical medium
    In a nonlimiting embodiment, the optical means 3 is:
    - a reflector;
    - a lens ; or
    - a light guide; or
    - a collimator.
    The optical means 3 cooperate with the light source 7 described below to form the light rays 4.
    In the nonlimiting example illustrated in FIGS. 1, 2, 10 and 11, the optical means 3 is a reflector which comprises a mirror 31 and a base 30.
    • Bright Squfce.
    In addition to the light emitting means 11 and the mechanical support 13, the light source 7 comprises an electrical connection interface 16. The electrical connection interface 16 is suitable for the power supply and the control of the emission means of light 11.
    The electrical connection interface 16 is adapted to cooperate with an external electrical connector which makes it possible to send control commands to the light source 7 and to supply it.
    The light source 7 is adapted to cooperate with the optical module 3. In a nonlimiting embodiment, the light source 7 comprises a plurality of light emitting means 11. In the nonlimiting example illustrated in FIGS. 3, 4, 5, 6, 7 and 9, there are six ways of emitting light.
    In a nonlimiting embodiment, the light emitting means 11 comprise at least one semiconductor emitting chip.
    In a nonlimiting variant, a semiconductor emitting chip is part of a light emitting diode. By light-emitting diode is meant any type of light-emitting diode, whether in non-limiting examples of LEDs (“Light Emitting Diode”), an OLED (“Organic LED”) or an AMOLED (“Active-Matrix3055397 ίο
    Organic LED "), or even a FOLED (" Flexible OLED ").
    The light source 7 is removable, namely it can be removed from the light module 10 without removing the optical module 3 from said light module 10. The light source 7 is thus interchangeable.
    • Support, optical means
    In a nonlimiting embodiment, the support 5 of the optical means 3 is a radiator which allows the heat coming from the light source 7 to be removed from the light module 10.
    The support 5 of the optical means 3 is movable in translation relative to the optical means 3 and it is its movement between the locked position and the unlocked position which will allow the light source 7 to be removed from the light module 10.
    In a nonlimiting embodiment, it is the user who ensures the translational movement of the support 5 of the optical means 3 between the unlocking position and the locking position. In the unlocked position, the light source 7 can be removed from the light module
    10. In the locking position, the optical means 3 and the support 5 of the optical means 3 are mechanically connected by locking means 52A, 52B, 52A, 52B 'so as to lock the support of the optical means 3 relative to said optical means 3 and a blocking of the light source 7 in the light module 10.
    In a nonlimiting embodiment as illustrated in FIG. 12, the locking means comprise two pairs of slides 52A, 52B, 52A, 52B 'arranged on either side of the light source 7. These pairs of slides are adapted to lock stably on each side of the light source 7, the support 5 of the optical means 3 relative to said optical means 3. The slides are more or less spaced relative to the base 50 of the support 5 of the optical means 3 .
    In a nonlimiting embodiment, each slide 52A, 52B, 52A ’, 52B’ comprises respectively:
    - a counterpart 32A, 32B, 32A ‘, 32B’ belonging to optical means 3;
    - A lug 51A, 51 B, 51 A ’, 51 B’ belonging to the support 5 of the optical means 3 adapted to cooperate respectively with said counterpart 32A, 32B, 32A ‘, 32B’;
    at least one leaf spring 33A, 33B, 33A ', 33B' belonging to the optical means 3 adapted to hold the lug 51 A, 51 B, 51 A ', 51 B' respectively in the counterpart 32A, 32B, 32A ', 32B '.
    In the side view of the light module 10 in FIG. 1, the counterparts 32A, 32B, the lug 51 B, the two leaf springs 33A, 33B are shown.
    As illustrated in FIG. 12, the counterparts 32A, 32A 'situated at the front of the light module 10 have a distance D1, DT less than the distance D2, D2' from the counterparts 32B, 32B 'situated at the rear of the light module. During the translation of the support 5 of the optical means 3 relative to the optical means 3, the pins 51 A, 51 A 'pass between the counterparts 32B, 32B' before being blocked by the counterparts 32A, 32A '.
    Thus, each counterpart of the optical means 3 is adapted to block in translation the corresponding lug of the support of the optical means 3. Each spring blade ensures that the corresponding lug remains locked against a corresponding counterpart, in the locking position of the support optical means 3.
    In the locking position of the support 5 of the optical means 3, as shown in FIG. 2:
    - The optical means 3 and the support 5 of the optical means 3 are in contact. More particularly, the base 30 of the optical means 3 and the base 50 of the support 5 of the optical means 3 are in contact;
    - The first housing 12A and the second housing 12B are opposite one another;
    the light source 7 is blocked in the light module 10. More particularly, the mechanical support 13 of the light emission means 11 is:
    - blocked horizontally in the first housing 12A of the optical means 3 and in the second housing 12B of the support 5 of the optical means 3;
    - blocked vertically by the optical means 3 against the support 5 of this optical means 3.
    The light source 7 is thus held in position in the optical module 3. In this way, the light emitting means 11 of the light source 7 are positioned and locked in a focal zone F of the optical means 3. This makes it possible to '' have a good focus on the optical module 3 and thus optimize the light beam.
    It will be noted that there is a thermal interface (not shown) between the mechanical support 13 and the support 5 of the optical means 3. This thermal interface makes it possible to ensure thermal conductivity between the mechanical support 13 and the light source 7.
    In a nonlimiting embodiment, the light source 7 is blocked in the second housing 12B and the first housing 12A when the support 5 of the optical means 3 is in the locked position:
    - in a longitudinal direction X at at least one primary reference point 9A, 9B, 9C (described below) by means of at least one primary blocking means 14A, 14B, 26 (described below) of the base 30 of the optical means 3 or the base 50 of the support of the optical means 5;
    - in a transverse direction Y, perpendicular to the longitudinal direction X, at least one secondary reference point 15A, 15B, 15C (described below) by means of at least one secondary locking means 18A, 18B, 19 (described below) of the base 30 of the optical means 3 or of the base 50 of the support of the optical means 5.
    In a nonlimiting embodiment, the primary locking means is a leaf spring 14A, 14B.
    In another nonlimiting embodiment, the primary locking means is a chamfer 26.
    In a nonlimiting embodiment, the secondary locking means is a chamfer 18A, 18B or a leaf spring 19.
    In a nonlimiting embodiment, the light source 7 is blocked in the first housing 12A and the second housing 12B when the support 5 of the optical means 3 is in the locking position, in a normal direction Z at tertiary reference points 25A , 25B, 25C, on which the support 5 of the optical module 3 (in particular its base 50) comes to bear when the support 5 of the optical module 3 is in the locked position.
    In a nonlimiting embodiment illustrated in FIG. 9, the light source 7 comprises three tertiary reference points 25A, 25B, 25C adapted to cooperate with three tertiary locking means 17A, 17B and 17C to block the mechanical support 13 of the light source 7 against the bottom of the first housing 12A in the normal direction Z.
    Note that in Figure 9, the three tertiary reference points 25A, 25B, 25C are dotted because they are positioned on the face of the mechanical support 3 which is opposite to that on which are positioned the light emitting means 11 and the electrical connection interface 16.
    In a nonlimiting embodiment illustrated in FIG. 10, the tertiary locking means are three leaf springs 17A, 17B, 17C arranged on the base 50 of the support 5 of the optical means 3. These spring blades 17A, 17B, 17C are placed progressively in tension as the support 5 of the optical means 3 moves relative to the optical means 3. The leaf springs 17A, 17B, 17C press on the mechanical support 13 light-emitting means 11 so that in the locked position, the support 5 of the optical means 3 keeps the light source 7 in position in the normal direction Z. Thus, the mechanical support 13 presses on the base 30 of the optical means 3 in the normal direction Z.
    The base 50 thus makes it possible to manage the Z isostatism of the light source 7 via the tertiary reference points 25A, 25B, 25C.
    In a nonlimiting embodiment, as illustrated in FIG. 9, the light source 7 also comprises a protective cover 27. The protective cover 8 includes an opening for letting the light emitted by the light source 7 pass. Thanks to the spring blades 17A, 17B, 17C, the protective cover 27 comes to bear against the base 30 of the optical means 3 when the support 5 of the optical means 3 is in the locked position.
    In the unlocking position of the support 5 of the optical means 3, as shown in FIG. 1:
    - The optical means 3 and the support 5 of the optical means 3 are spaced from each other so as to allow the withdrawal of the light source 7. It will be noted that in this case the base 30 of the optical means 3 and the base 50 of the support 5 of the optical means 3 can be in contact or not;
    - The first housing 12A and the second housing 12B are distant from each other, they are no longer opposite;
    the light source 7 remains blocked in the second housing 12B but is accessible and can be removed from the light module 10.
    The light module 10 of Figures 1 and 2 is described below according to three non-limiting embodiments.
    • First mod_e_ of_ realization
    The light module 10 comprises the optical means 3, the support 5 of the optical means 3 and the light source described above. In this first embodiment, the support 5 of the optical means 3 is movable in translation relative to the optical means 3 in the longitudinal direction X.
    Figures 3 and 4 schematically respectively represent the base 30 of the optical means 3 and the base 50 of the support 5 of the optical means 3 of the light module 10 according to a first non-limiting embodiment.
    In a nonlimiting example, the optical means 3 is a reflector.
    The optical means 3 comprises a base 30 and a mirror 31. The mirror 31 performs the optical functions of the optical means 3. The base 30 supports the mirror 31 and includes a contact surface intended to come into contact with the base 50 of the support 5 of the optical means 3. This base 30 delimits the first housing 12A of the optical means 3 illustrated in FIG. 3.
    The mechanical support 13 of the light source 7 comprises two arms adapted to form two primary reference points 9A, 9B.
    When the support 5 of the optical means 3 is in the unlocked position, the light source 7 is positioned by the operator in the second housing 12B of the optical means 3, illustrated in FIG. 4.
    In the unlocked position, two primary locking means 14A, 14B are in contact with the mechanical support 13 of the light source 7, and there is a clearance 01 in the longitudinal direction X as illustrated in FIG. 4 between the end of the mechanical support 13 on the side of which are the light emitting means 11 and the edge of the base 50 of the support 5. This makes it possible to pre-position the light source 7 in the housing 12B.
    When the support 5 of the optical means 3 is pushed in translation in the longitudinal direction X in the optical means 3, the mechanical support 13 is also housed in the first housing 12A of the base 30 of the optical means 3, illustrated in FIG. 3 .
    When the lugs 51 B, 51 B ’, 51 A, 51 A’ described above come into abutment respectively against the counterparts 32B, 32B ’, 32A, and 32A’, the support 5 of the optical means 3 is then in the locked position.
    As has already been specified, it is the translation of the support 5 of the optical means 3, in the longitudinal direction X, which allows the first housing 12A and the second housing 12B to face each other and the two bases 30 and 50 in contact.
    When the support 5 of the optical means 3 is in the locked position, in the second housing 12B, the mechanical support 13 is locked in the longitudinal direction X by two primary locking means 14A, 14B of the base 50 of the support 5 of the optical means 3, illustrated in FIG. 4. These two primary locking means 14A, 14B act on the mechanical support 13 of the light emission means 11, so that the two primary reference points 9A, 9B, illustrated in FIG. 3 , are in abutment against the internal wall of the housing 12A. The base 30 of the optical means 3 thus makes it possible to manage the isostatism in X of the light source 7 via the primary reference points 9A, 9B. At this time, the two primary blocking means 14A, 14B are constrained and the clearance 01 can change (for example increase) when the light source 7 is blocked in the first housing 12A at the two primary reference points 9A, 9B.
    In a nonlimiting embodiment, the two primary locking means 14A, 14B are two leaf springs. These two leaf springs allow the light source 7 to be easily placed in the light module 10 in the longitudinal direction X.
    When the support 5 of the optical means 3 is in the locked position, in the first housing 12A, the mechanical support 13 is blocked in the transverse direction Y by a secondary blocking means 19 illustrated in FIG. 3. The secondary blocking means 19 acts on the mechanical support 13 at the secondary reference point 15C, illustrated in FIG. 3.
    At this time, there is no play between the end of the mechanical support 13 of the light source 7 and the edge of the base 30 of the optical means 3 as illustrated in FIG. 3.
    In a nonlimiting embodiment, the secondary locking means 19 is a leaf spring. This leaf spring makes it possible to easily place the light source 7 in the light module 10 in the transverse direction Y.
    In this first embodiment for blocking the light source 7, this light source is therefore positioned first in the second housing 12B of the support 5 of the optical means 3 and then in the first housing 12A optical means 3. By proceeding in this way, it is ensured that the light source 7 is precisely positioned in the light module 10 and that it remains stable in this position.
    • Second mpd_e_ de.réalisation
    The light module 10 comprises the optical means 3, the support 5 of the optical means 3 and the light source 7 described above. In this second embodiment, the support 5 of the optical means 3 is movable in translation relative to the optical means 3 in the longitudinal direction Y.
    Figures 5, 6 and 7 show schematically respectively the base 30 of the optical means 3 and the base 50 of the support 5 of the optical means 3 of the light module 10 according to a second nonlimiting embodiment.
    In a nonlimiting example, the optical means 3 is a reflector.
    The optical means 3 comprises a base 30 and a mirror 31. The mirror 31 performs the optical functions of the optical means 3. The base 30 supports the mirror 31 and includes a contact surface intended to come into contact with the base 50 of the support 5 of the optical means 3. This base 30 delimits the first housing 12A of the optical means 3 illustrated in FIG. 5.
    The mechanical support 13 of the light source 7 comprises two arms, one of which is adapted to form a primary reference point 9C (the left arm in the nonlimiting example illustrated in FIG. 5).
    Thus, when the support 5 of the optical means 3 is in the unlocked position, the light source 7 is positioned by the operator in the second housing 12B of the support 5 of the optical means 3 as illustrated in FIG. 6.
    In the unlocked position, two secondary locking means 18A, 18B of the base 50 of the support 5 of the optical means 3 come into contact with two secondary reference points 15A, 15B of the mechanical support 13 of the light source 7, and there are a clearance 02 in the longitudinal direction Y as illustrated in FIG. 6 between the arm of the mechanical support 13 opposite the two secondary reference points 15A, 15B and the edge of the base 50 of the support 5. This makes it possible to pre-position the light source 7 in the housing 12B.
    When the support 5 of the optical means 3 is pushed in translation in the transverse direction Y in the optical means 3, the mechanical support 13 also comes to be housed in the first housing 12A of the base 30 of the optical means 3, illustrated in FIG. 5 .
    When the lugs 51 B, 51 B ’, 51 A, 51 A’ described above come into abutment respectively against the counterparts 32B, 32B ’, 32A, and 32A’, the support 5 of the optical means 3 is then in the locked position.
    The arrangement of the slides 52A, 52B, 52A ’, 52B’ comprising these lugs and these counterparts is different from that defined in the first embodiment. They are arranged so that they allow translation of the light source 7 in the transverse direction Y.
    As has already been specified, it is the translation of the support 5 of the optical means 3 in the transverse direction Y which makes it possible to put the first housing 12A and the second housing 12B opposite and the two bases 30 and 50 in touch.
    As illustrated in FIG. 5, when the support 5 of the optical means 3 is in the locked position, the light source 7, more particularly the mechanical support 13, is blocked in the first housing 12A in the longitudinal direction X at a point primary reference 9C by means of a primary blocking means 26 of the base 30 of the optical means 3.
    The base 30 of the optical means 3 thus makes it possible to manage the isostatism in X of the light source 7 via the primary reference point 9C.
    At this time, there is no play between the end of the mechanical support 13 of the light source 7 (on the side of which the light emission means 11 are located) and the edge of the base 30 of the optical means 3 as illustrated in FIG. 5, nor between the arm (left in FIG. 5) of the mechanical support 13 and the edge of the base 30 of the optical means as illustrated in FIG. 5.
    Note that to push in translation the support 5 of the optical means 3 in the transverse direction Y, the base 30 of the optical means 3 has an opening 39 provided for this purpose (illustrated in Figure 5).
    In another illustrated nonlimiting embodiment, the primary locking means 26 is a leaf spring. This leaf spring makes it possible to easily place the light source 7 in the light module 10 in the longitudinal direction X.
    In another nonlimiting embodiment (not illustrated), the primary locking means 26 and is a chamfer. The chamfer allows progressive guidance and blocking of the light source 7 in the light module 10, in the longitudinal direction X.
    As illustrated in FIG. 6, when the support 5 of the optical means 3 is in the locked position, the light source 7, more particularly the mechanical support 13, is blocked in the transverse direction Y at two secondary reference points 15A, 15B by means of two secondary blocking means 18A, 18B of the base 50 of the support 5 of the optical means
    3. At this time the two secondary blocking means 18A, 18B are forced and the clearance 02 can change (for example increase) when the light source 7 is blocked in the first housing 12A at the primary reference point 9C.
    In a nonlimiting embodiment (not shown), the two secondary locking means 18A, 18B are leaf springs.
    In another nonlimiting embodiment illustrated, the two secondary locking means 18A, 18B are chamfers. The chamfers allow progressive guidance and blocking of the light source 7 in the light module 10, in the transverse direction Y.
    Figure 8 is a sectional view A-A of Figure 6 at the chamfer 18B. This chamfer 18B comprises a bevelled part 53A and a straight part 53B extending the beveled part 53A. The bevelled part 53A is adapted to guide the light source 7 (illustrated in dotted lines in a non-locked position) in the transverse direction Y and in the normal direction Z when said light source 7 is placed in the support 5 of the optical means 3, c that is to say when this support 5 of the optical means 3 is in an unlocked position. The light source 7 thus moves progressively until its mechanical support 13 touches the bottom of the housing 12B. At this moment, the right part 53B blocks the light source (illustrated in solid lines) in the housing 12B of the support 5 of the optical means 3.
    According to a first non-limiting alternative embodiment illustrated in the figure
    6, the two secondary locking means 18A, 18B are brought together and are located at the front of the light module 10. When the support 5 of the optical means 3 is in a locking position, the two secondary locking means 18A, 18B take support on an arm of the light source 7. According to a second nonlimiting alternative embodiment illustrated in the figure
    7, the spacing between the two secondary locking means 18A and 18B is greater. The secondary blocking means 18B is thus located at the rear of the light module 10. When the support 5 of the optical means 3 is in a locked position, the secondary blocking means 18A is supported on one of the arms of the light source 7 The secondary blocking means 18B is supported on the body of the light source 7.
    In this way, the blocking stability in the transverse direction Y of the mechanical support 13 is improved.
    It will be noted that for the chamfer 18A in FIG. 7 and the chamfer 26 in FIG. 5, the same principle of progressive blocking as that described for the chamfer 18B in FIG. 8 applies. Thus, Figure 8 applies to the chamfer 18A. In addition, a figure similar to FIG. 8 applies to the chamfer 26 of FIG. 5 by replacing the reference 50 by the reference 30.
    As described above, the electrical connection interface 16 of the light source 7 is adapted to cooperate with an external electrical connector 37 (illustrated in FIG. 11) of the light source 7. In order to avoid disconnection of this external electrical connector during the use of the motor vehicle, in a nonlimiting embodiment illustrated in FIG. 12, the light module 10 also comprises wedging means 35 for holding the external electrical connector 37 on the light module 10. The means wedging 35 belong to the base 50 of the support 5 of the optical means 3.
    Of course, the description of the invention is not limited to the embodiments described above.
    Thus, in a nonlimiting embodiment, provision is made to deposit on the internal walls of the second housing 12B a paste or a thermally conductive foam to promote the evacuation of the heat emitted by the light emitting means 11 towards the support 5 of the optical means
    3.
    Thus, in a nonlimiting embodiment, the translation of the support 5 of the optical means 3 relative to the optical module 3 can be carried out according to the same principle described in a diagonal direction with a component in the longitudinal direction X and a component in the transverse direction Y.
    Thus, the invention described has the following advantages in particular:
    - it facilitates the replacement of a defective light source;
    - it is not necessary to remove the optical means 3 to perform the replacement operation;
    - It is not necessary to discard all the optical means 3 just to replace a light source, which significantly reduces the cost of replacing said light source;
    - once the light source has been removed, it is possible to identify and change only the defective element of this light source 7;
    - a simple system to use is used to release the light source. The operator just has to translate the support 5 of the optical means 3 relative to said optical means 3; either in the longitudinal direction X or in the transverse direction Y.
