• Source lumineuse 11 • Light source 11

• Moyen optique 12 • Optical medium 12

Le moyen optique 12 est illustrée sur les figures 1 et 3a à 6.The optical means 12 is illustrated on the figures 1 and 3a to 6 .

Il est adapté pour coopérer avec les rayons lumineux R de ladite source lumineuse 11.

It is further adapted to fix at least one support 110 of a light source 11.

Dans un mode de réalisation non limitatif, le moyen optique 12 est une lentille et/ou un réflecteur et/ou un guide de lumière et/ou un collimateur.In a nonlimiting embodiment, the optical means 12 is a lens and / or a reflector and / or a light guide and / or a collimator.

Dans un mode de réalisation non limitatif, ledit moyen optique 12 comprend une pluralité de secteurs dédiés à la fonction d'éclairage Fct. Par exemple, dans le cas d'un réflecteur, il pourra comporter plusieurs facettes juxtaposées ou bien dans le cas d'une lentille de projection, elle pourra comporter plusieurs portions aux propriétés optiques distinctes.In a nonlimiting embodiment, said optical means 12 comprises a plurality of sectors dedicated to the lighting function Fct. For example, in the case of a reflector, it may comprise several juxtaposed facets or else in the case of a projection lens, it may comprise several portions with distinct optical properties.

Le moyen optique 12 comprend en outre :

  • une base 124 sur laquelle peut reposer le support 110 de la source lumineuse 11 ;
  • au moins une cavité 121 adaptée pour recevoir la surface émettrice 111 d'une source lumineuse 11 ;
  • une surface réfléchissante 126 adaptée pour coopérer avec les rayons lumineux R d'au moins une source lumineuse 11 de sorte à produire un sous-segment lumineux S illustré sur la figure 1.
The optical means 12 further comprises:

  • at least one cavity 121 adapted to receive the emitting surface 111 of a light source 11;
  • a reflecting surface 126 adapted to cooperate with the light rays R of at least one light source 11 so as to produce a light sub-segment S illustrated on the figure 1 .

Dans un mode de réalisation non limitatif, le moyen optique 12 comprend en outre un foyer 122, à partir duquel partent les rayons lumineux R d'une source lumineuse 11. Le moyen optique 12 est adapté pour diriger les rayons lumineux R vers une direction voulue. La surface émettrice de lumière 111 vient se placer dans la cavité 121 au foyer 122 du moyen optique 12. Tel qu'illustré sur la figure 1, les rayons lumineux R émis par la surface émettrice 111 parviennent à la surface réfléchissante 126 du moyen optique 12 et sont réfléchis dans la direction voulue de sorte à produire le sous-segment lumineux S.In a nonlimiting embodiment, the optical means 12 also comprises a focal point 122, from which the light rays R of a light source 11. The optical means 12 is adapted to direct the light rays R towards a desired direction. The light-emitting surface 111 is placed in the cavity 121 at the focal point 122 of the optical means 12. As illustrated in the figure 1 , the light rays R emitted by the emitting surface 111 reach the reflecting surface 126 of the optical means 12 and are reflected in the desired direction so as to produce the light sub-segment S.

Dans un premier mode de réalisation non limitatif illustré sur les figures 5a et 5c, un moyen optique 12 est adapté pour coopérer avec les rayons lumineux R d'une seule source lumineuse 11.In a first nonlimiting embodiment illustrated on the figures 5a and 5c , an optical means 12 is adapted to cooperate with the light rays R of a single light source 11.

Dans l'exemple non limitatif illustré sur la figure 5a, on a ainsi trois modules optiques 13 comprenant chacun un moyen optique 12 et trois sources lumineuses 11 respectivement associées à chacun des trois moyens optique 12. Dans l'exemple non limitatif illustré sur la figure 5c, on a ainsi un module optique 13 (celui de droite) comprenant un moyen optique 12 et une seule source lumineuse 11 associée.In the nonlimiting example illustrated on the figure 5a , there are thus three optical modules 13 each comprising an optical means 12 and three light sources 11 respectively associated with each of the three optical means 12. In the nonlimiting example illustrated in the figure 5c , there is thus an optical module 13 (the one on the right) comprising an optical means 12 and a single light source 11 associated.

Dans un deuxième mode de réalisation non limitatif illustré sur la figure 5b et 5c, un moyen optique 12 est adapté pour coopérer avec les rayons lumineux R d'une pluralité de sources lumineuses 11. Dans l'exemple non limitatif illustré sur la figure 5b, on a ainsi un module optique 13 qui comprend un moyen optique 12 adapté pour coopérer avec les rayons lumineux R de trois sources lumineuses 11. Dans l'exemple non limitatif illustré sur la figure 5c, on a ainsi un module optique 13 (celui de gauche) qui comprend un moyen optique 12 adapté pour coopérer avec les rayons lumineux R de deux sources lumineuses 11.In a second nonlimiting embodiment illustrated on the figure 5b and 5c , an optical means 12 is adapted to cooperate with the light rays R of a plurality of light sources 11. In the nonlimiting example illustrated in the figure 5b , there is thus an optical module 13 which comprises an optical means 12 adapted to cooperate with the light rays R of three light sources 11. In the nonlimiting example illustrated in the figure 5c , there is thus an optical module 13 (the one on the left) which comprises an optical means 12 adapted to cooperate with the light rays R of two light sources 11.

Bien entendu, ces deux modes de réalisation peuvent être combinés entre eux tel qu'illustré sur la figure 5c.Of course, these two embodiments can be combined together as illustrated in the figure 5c .

Par ailleurs, dans un premier mode de réalisation non limitatif illustré sur la figure 5a et 5c, le moyen optique 12 ne comprend qu'une seule cavité 121 adaptée pour coopérer avec une seule source lumineuse 11. Ainsi, un moyen optique 12 ne peut coopérer avec des rayons lumineux R que d'une seule source lumineuse 11. Comme illustré sur la figure 5a, on a trois moyens optiques 12 comportant chacun une seule cavité 121 coopérant avec une seule source lumineuse 11, à savoir une seule surface émettrice 111 peut être placée dans ladite cavité 121. Comme illustré sur la figure 5c, on a un moyen optique 12 (celui de droite) comportant une seule cavité 121 coopérant avec une seule source lumineuse 11.Furthermore, in a first nonlimiting embodiment illustrated on the figure 5a and 5c , the optical means 12 comprises only a single cavity 121 adapted to cooperate with a single light source 11. Thus, an optical means 12 can only cooperate with light rays R only light source 11. As illustrated on the figure 5a , there are three optical means 12 each comprising a single cavity 121 cooperating with a single light source 11, namely a single emitting surface 111 can be placed in said cavity 121. As illustrated in the figure 5c , there is an optical means 12 (the one on the right) comprising a single cavity 121 cooperating with a single light source 11.

Par ailleurs, dans un deuxième mode de réalisation non limitatif illustré sur les figures 5b et 5c, le moyen optique 12 comprend une pluralité de cavités 121, une source lumineuse 11 coopérant avec chaque cavité 121. Ainsi, un moyen optique 12 peut coopérer avec des rayons lumineux R de plusieurs sources lumineuses 11. Comme illustré sur la figure 5b, on a un seul moyen optique 12 qui comprend trois cavités 121 coopérant chacune avec une source lumineuse 11, à savoir une surface émettrice 111 est placée dans chaque cavité 121. Comme illustré sur la figure 5c, on a un moyen optique 12 (sur la gauche) qui comprend deux cavités 121 coopérant chacune avec une source lumineuse 11.Furthermore, in a second nonlimiting embodiment illustrated on the figures 5b and 5c , the optical means 12 comprises a plurality of cavities 121, a light source 11 cooperating with each cavity 121. Thus, an optical means 12 can cooperate with light rays R from several light sources 11. As illustrated in the figure 5b , there is a single optical means 12 which comprises three cavities 121 each cooperating with a light source 11, namely an emitting surface 111 is placed in each cavity 121. As illustrated in the figure 5c , there is an optical means 12 (on the left) which comprises two cavities 121 each cooperating with a light source 11.

Bien entendu, ces deux modes de réalisation peuvent être combinés tel qu'illustré sur la figure 5c.Of course, these two embodiments can be combined as illustrated in the figure 5c .

Dans un mode de réalisation non limitatif, le module optique 12 comprend en outre une partie du pivot 123 décrit ci-après.In a nonlimiting embodiment, the optical module 12 also comprises a part of the pivot 123 described below.

• Support 110 • Support 110

Le support 110 est illustré sur les figures 1 et 3a à 6.The support 110 is illustrated on the figures 1 and 3a to 6 .

Tel qu'illustré sur la figure 6, il est adapté pour recevoir et fixer au moins une source lumineuse 11. Il comprend au moins une cavité 1100 permettant le passage d'une source lumineuse 11.As shown in the figure 6 , it is adapted to receive and fix at least one light source 11. It comprises at least one cavity 1100 allowing the passage of a light source 11.

Dans un mode de réalisation non limitatif, le support 110 comprend en outre au moins une encoche 1101 permettant le passage d'une baïonnette du dispositif à baïonnettes 112. Dans l'exemple non limitatif illustré sur la figure 6, il comprend trois encoches 1101. Cela permet de démonter/monter ladite source lumineuse 11.In a nonlimiting embodiment, the support 110 further comprises at least one notch 1101 allowing the passage of a bayonet of the bayonet device 112. In the nonlimiting example illustrated in the figure 6 , it comprises three notches 1101. This makes it possible to disassemble / mount said light source 11.

Le support 110 est amovible en rotation par rapport audit moyen optique 12. Il pivote ainsi par rapport audit moyen optique 12 autour d'un axe A illustré sur la figure 1 défini par un pivot 123. Le pivot 123 est ainsi adapté pour faire tourner en rotation ledit support 110. En pivotant ledit support 110 permet de rendre plus accessible la source lumineuse 11.The support 110 is removable in rotation relative to said optical means 12. It thus pivots relative to said optical means 12 about an axis A illustrated on the figure 1 defined by a pivot 123. The pivot 123 is thus adapted to rotate said support 110 in rotation. By pivoting said support 110 makes the light source 11 more accessible.

Dans un mode de réalisation non limitatif, le pivot 123 est solidaire ou non du moyen optique 12 ou du boîtier 10. Ainsi, dans un mode de réalisation non limitatif, le pivot 123 est réalisé en partie sur le moyen optique 12 et en partie sur le support 110. Ainsi, dans un exemple de réalisation non limitatif, le pivot 123 comprend un tourillon disposé sur le moyen optique 12 adapté pour coopérer avec un trou dans le support 110.In a nonlimiting embodiment, the pivot 123 is integral or not with the optical means 12 or the housing 10. Thus, in a nonlimiting embodiment, the pivot 123 is made partly on the optical means 12 and partly on the support 110. Thus, in a nonlimiting exemplary embodiment, the pivot 123 comprises a pin arranged on the optical means 12 adapted to cooperate with a hole in the support 110.

Le support 110 est adapté pour prendre :

  • une position déverrouillée p1 tel qu'illustré sur la figure 1 ;
  • une position verrouillée p2 tel qu'illustré sur les figures 3a et 3b.
The support 110 is adapted to take:
  • an unlocked position p1 as illustrated on the figure 1 ;
  • a locked position p2 as illustrated on the Figures 3a and 3b .

Dans la position déverrouillée p1, le support 110 n'est pas plaqué contre la base 124 du moyen optique 12 et est libre en rotation. Par ailleurs la surface émettrice 111 de la source lumineuse 11 se trouve hors de toute cavité 121 du moyen optique 12.In the unlocked position p1, the support 110 is not pressed against the base 124 of the optical means 12 and is free to rotate. Furthermore, the emitting surface 111 of the light source 11 is outside any cavity 121 of the optical means 12.

Dans la position verrouillée p2, le support 110 est plaqué contre la base 124 du moyen optique 12 et n'est pas libre en rotation. Par ailleurs, la surface émettrice 111 de la source lumineuse 11 est placée dans une cavité 121 du moyen optique 12. Elle est en particulier placée au foyer 122 dudit moyen optique 12.In the locked position p2, the support 110 is pressed against the base 124 of the optical means 12 and is not free to rotate. Furthermore, the emitting surface 111 of the light source 11 is placed in a cavity 121 of the optical means 12. It is in particular placed at the focus 122 of said optical means 12.

Comme illustré sur la vue de face de la figure 4, ledit support 110 comprend au moins un décrochement 114 de sorte à placer lesdites sources lumineuses 11 sur des plans différents qui sont parallèles à l'axe longitudinal B dudit support 110. Comme on peut le voir sur l'exemple non limitatif illustré, la source lumineuse 11 centrale est décalée par rapport aux sources lumineuses 11 adjacentes placées de part et d'autre. Le décalage se fait ainsi selon un axe perpendiculaire à l'axe longitudinal B dudit support 110.As illustrated in the front view of the figure 4 , said support 110 comprises at least one step 114 so as to place said light sources 11 on different planes which are parallel to the longitudinal axis B of said support 110. As can be seen in the nonlimiting example illustrated, the source central light 11 is offset from the adjacent light sources 11 placed on either side. The offset is thus made along an axis perpendicular to the longitudinal axis B of said support 110.

Dans un premier mode de réalisation non limitatif illustré sur les figures 5a, 5b ou 5c, un support 110 est adapté pour coopérer avec un seul moyen optique 12. Comme illustré sur la figure 5a, on a trois supports 110 différents pour trois moyens optiques 12 différents. Comme illustré sur la figure 5b, on a un seul support 110 qui coopère avec un seul moyen optique 12.In a first nonlimiting embodiment illustrated on the Figures 5a, 5b or 5c , a support 110 is adapted to cooperate with a single optical means 12. As illustrated in the figure 5a , there are three different supports 110 for three different optical means 12. As illustrated in the figure 5b , there is a single support 110 which cooperates with a single optical means 12.

Dans un deuxième mode de réalisation non limitatif illustré sur la figure 5c, un support 110 est adapté pour coopérer avec une pluralité de moyens optiques 12. Comme illustré sur la figure 5c, on a un seul support 110 pour deux moyens optiques 12.In a second nonlimiting embodiment illustrated on the figure 5c , a support 110 is adapted to cooperate with a plurality of optical means 12. As illustrated in the figure 5c , there is a single support 110 for two optical means 12.

Bien entendu, ces deux modes de réalisation non limitatifs peuvent être combinés, comme illustré sur la figure 5c.Of course, these two nonlimiting embodiments can be combined, as illustrated in the figure 5c .

Le support 110 est fixé au moyen optique 12 grâce au dispositif de verrouillage 120 décrit ci-après.The support 110 is fixed to the optical means 12 by means of the locking device 120 described below.

• Dispositif de verrouillage 120 • Locking device 120

Le dispositif de verrouillage 120 est illustré sur les figures 1 et 3a et 3b.The locking device 120 is illustrated on the figures 1 and 3a and 3b .

Le dispositif de verrouillage 120 est adapté pour verrouiller/déverrouiller le support 110 par rapport au moyen optique 12 et donc de le fixer audit moyen optique 12. Dans un mode de réalisation non limitatif, le verrouillage/déverrouillage s'effectue de manière manuelle, A cet effet, un opérateur verrouille/déverrouille le support 110 en agissant sur le dispositif de verrouillage 120.The locking device 120 is adapted to lock / unlock the support 110 relative to the optical means 12 and therefore to fix it to said optical means 12. In a nonlimiting embodiment, the locking / unlocking is carried out manually, A for this purpose, an operator locks / unlocks the support 110 by acting on the locking device 120.

∘ Premier mode de réalisation∘ First embodiment

Dans un premier mode de réalisation illustré sur la figure 3a, le dispositif de verrouillage 120 est une languette élastique. Tel qu'illustré, la languette élastique 120 part de la base 124 du module optique 12 et s'étend perpendiculairement à ladite base 124.In a first embodiment illustrated on the figure 3a , the locking device 120 is an elastic tongue. As illustrated, the elastic tongue 120 starts from the base 124 of the optical module 12 and extends perpendicular to said base 124.

Lorsque le dispositif de verrouillage 120 est un une languette élastique, pour verrouiller ledit support 110, l'opérateur exerce une pression sur la source lumineuse 11 via son radiateur 113 ou son support 110 par exemple pour la faire pivoter avec son support autour de l'axe A du pivot 123 de sorte qu'une extrémité du support 110 se trouve prisonnière de la languette élastique 120 et que ledit support 110 soit plaqué contre la base 124 du moyen optique 12. La surface émettrice 111 de la source lumineuse 11 est ainsi placée dans la cavité 121 et au foyer 122 dudit moyen optique 12. Ladite source lumineuse 11 peut fonctionner correctement.When the locking device 120 is an elastic tongue, to lock said support 110, the operator exerts pressure on the light source 11 via its radiator 113 or its support 110 for example to rotate it with its support around the axis A of the pivot 123 so that one end of the support 110 is trapped in the elastic tongue 120 and that said support 110 is pressed against the base 124 of the optical means 12. The emitting surface 111 of the light source 11 is thus placed in the cavity 121 and at the focus 122 of said optical means 12. Said light source 11 can function correctly.

Pour déverrouiller le support 110, l'opérateur tire sur ladite languette élastique 120 vers l'arrière afin de rendre le support 110 libre en rotation et ainsi de le déverrouiller. On peut prévoir un ressort de rappel dans le pivot 123 pour que le support 110 revienne automatiquement en position parallèle à l'ouverture 100.To unlock the support 110, the operator pulls on said elastic tongue 120 backwards in order to make the support 110 free to rotate and thus to unlock it. A return spring can be provided in the pivot 123 so that the support 110 automatically returns to the position parallel to the opening 100.

Ainsi, lorsque le support 110 est déverrouillé, l'opérateur peut alors faire pivoter le support 110 autour de l'axe A du pivot 123 et tirer l'ensemble support 110 et source lumineuse 11 en arrière jusqu'à mettre le support 110 sensiblement parallèle à l'ouverture 100 du boîtier 10 de sorte que la (les) source(s) lumineuse(s) 11 se trouve(nt) en regard de ladite ouverture 100. Dans cette position l'opérateur peut facilement retirer la (les) source(s) lumineuse(s) 11 du support 110 pour la (les) remplacer, sans pour autant remplacer les autres éléments du dispositif lumineux 1 ou tout le dispositif lumineux 1.Thus, when the support 110 is unlocked, the operator can then pivot the support 110 around the axis A of the pivot 123 and pull the support 110 and light source 11 assembly backwards until the support 110 is substantially parallel. at the opening 100 of the housing 10 so that the light source (s) 11 is (are) facing said opening 100. In this position the operator can easily remove the source (s) (s) light (s) 11 of the support 110 to replace them, without replacing the other elements of the light device 1 or the whole light device 1.

∘ Deuxième mode de réalisation∘ Second embodiment

Dans un deuxième mode de réalisation illustré sur la figure 3b, le dispositif de verrouillage 120 est un verrou rotatif. Dans un exemple non limitatif illustré, le verrou rotatif est un ressort flexible. Dans ce cas, on notera que la base 124 du moyen optique 12 comprend deux crochets 125 disposés de part et d'autre du support 110 quand celui-ci est en position verrouillée p2 adaptés pour garder le ressort flexible accroché et en position. On notera que sur la figure 3b, un seul crochet 125 est illustré puisque c'est une vue de profil.In a second embodiment illustrated on the figure 3b , the locking device 120 is a rotary lock. In a nonlimiting example illustrated, the rotary lock is a flexible spring. In this case, it will be noted that the base 124 of the optical means 12 comprises two hooks 125 arranged on either side of the support 110 when the latter is in the locked position p2 adapted to keep the flexible spring hooked and in position. Note that on the figure 3b , a single hook 125 is illustrated since it is a profile view.

Lorsque le dispositif de verrouillage 120 est un ressort flexible, pour verrouiller ledit support 110, l'opérateur exerce une pression sur la source lumineuse 11 via son radiateur 113 ou son support 110 par exemple pour la faire pivoter avec son support 110 autour de l'axe A du pivot 123 de sorte que ledit support 110 soit plaqué contre la base 124 du moyen optique 12. Puis il fait basculer le verrou rotatif 120, ici le ressort flexible, vers l'avant en le faisant pivoter de sorte que ce dernier passe au dessus de la source lumineuse 11 et vienne s'accrocher aux deux crochets 125 et rester ainsi en position. La surface émettrice 111 de la source lumineuse 11 est ainsi placée dans la cavité 121 et au foyer 122 dudit moyen optique 12. Ladite source lumineuse 11 peut fonctionner correctement.When the locking device 120 is a flexible spring, to lock said support 110, the operator exerts pressure on the light source 11 via its radiator 113 or its support 110 for example to rotate it with its support 110 around the axis A of pivot 123 so that said support 110 is pressed against the base 124 of the optical means 12. Then it causes the rotary lock 120, here the flexible spring, to tilt forwards by pivoting it so that the latter passes over the light source 11 and come to hang on the two hooks 125 and thus remain in position. The emitting surface 111 of the light source 11 is thus placed in the cavity 121 and at the focus 122 of said optical means 12. Said light source 11 can function correctly.

Pour déverrouiller le support 110, l'opérateur écarte le ressort flexible 120 vers l'extérieur du support 110 de sorte à le décrocher des crochets 125 et le fait pivoter vers l'arrière tel qu'indiqué par la flèche illustrée sur la figure 3b afin de rendre le support 110 libre en rotation et ainsi de le déverrouiller.To unlock the support 110, the operator moves the flexible spring 120 outwards from the support 110 so as to unhook it from the hooks 125 and makes it pivot backwards as indicated by the arrow illustrated in the figure 3b in order to make the support 110 free to rotate and thus to unlock it.

Ainsi, lorsque le support 110 est déverrouillé, l'opérateur peut alors faire pivoter le support 110 autour de l'axe A du pivot 123 et tirer l'ensemble support 110 et source lumineuse 11 en arrière jusqu'à mettre le support 110 sensiblement parallèle à l'ouverture 100 du boîtier 10 de sorte que la (les) source(s) lumineuse(s) 11 se trouve(nt) en regard de ladite ouverture 100. Dans cette position l'opérateur peut facilement retirer la (les) source(s) lumineuse(s) 11 du support 110 pour la (les) remplacer, sans pour autant remplacer les autres éléments du dispositif lumineux 1 ou tout le dispositif lumineux 1.Thus, when the support 110 is unlocked, the operator can then rotate the support 110 around the axis A of the pivot 123 and pull the support 110 and light source 11 assembly backwards until the support 110 is substantially parallel. at the opening 100 of the housing 10 so that the light source (s) 11 is (are) facing said opening 100. In this position the operator can easily remove the source (s) (s) light (s) 11 of the support 110 to replace them, without replacing the other elements of the light device 1 or the whole light device 1.

Bien entendu, la description de l'invention n'est pas limitée aux modes de réalisation décrits ci-dessus.Of course, the description of the invention is not limited to the embodiments described above.

Ainsi, dans un autre mode de réalisation non limitatif, le pivot 123 est réalisé en partie sur le boîtier 10 au lieu du moyen optique 12 et en partie sur le support 10.Thus, in another nonlimiting embodiment, the pivot 123 is produced partly on the housing 10 instead of the optical means 12 and partly on the support 10.

Ainsi, l'invention décrite présente notamment les avantages suivants :

  • Grâce à l'ajout du support 110 rotatif, elle facilite le remplacement d'une source lumineuse 11 défectueuse :
    • elle permet d'accéder simplement aux sources lumineuses 11 à remplacer par l'ouverture 100 du dispositif lumineux 1 et par le pivotement du support 110 sur lequel sont fixés les sources lumineuses 11 à remplacer et qui vient se placer en face de ladite ouverture 100 ;
    • elle permet de faire pivoter simplement un support 110 de sources lumineuses 11 en libérant le dispositif de verrouillage 120 ;
  • elle permet un remplacement rapide d'une source lumineuse 11 défectueuse ;
  • il n'est pas nécessaire de retirer du véhicule tout le dispositif lumineux 1 pour effectuer l'opération de remplacement d'une source lumineuse 11 ;
  • il n'est pas nécessaire de mettre au rebut tout le dispositif lumineux 1 juste pour remplacer une source lumineuse 11, ce qui réduit sensiblement le coût de remplacement de ladite source lumineuse 11;
  • elle permet de monter facilement une source lumineuse 11 sur son support 110 contrairement un système de montage d'une source lumineuse 11 directement sur un module optique associé.
Thus, the invention described has in particular the following advantages:
  • Thanks to the addition of the rotating support 110, it facilitates the replacement of a defective light source 11:
    • it allows simple access to the light sources 11 to be replaced by the opening 100 of the light device 1 and by the pivoting of the support 110 on which the light sources 11 to be replaced are fixed and which is placed opposite said opening 100;
    • it allows to simply rotate a support 110 of light sources 11 by releasing the locking device 120;
  • it allows rapid replacement of a defective light source 11;
  • it is not necessary to remove the entire light device 1 from the vehicle to perform the operation of replacing a light source 11;
  • it is not necessary to discard the entire light device 1 just to replace a light source 11, which significantly reduces the cost of replacing said light source 11;
  • it makes it possible to easily mount a light source 11 on its support 110 unlike a system for mounting a light source 11 directly on an associated optical module.
