Description

Description Description
BOITE A ILLUMINATION HOMOGENE POUR IMAGERIE PHOTOGRAPHIQUE OU PAR CAMERA HOMOGENEOUS ILLUMINATION BOX FOR PHOTOGRAPHIC OR CAMERA IMAGING
Domaine technique Technical area
[0001] La présente invention concerne une boite à illumination, pour effectuer la prise de vue d'un objet au moyen d'un appareil photographique ou d'une caméra, comportant une enveloppe définissant un logement, fermé, pour un objet à examiner et comprenant un fond et une couverture, un système d'illumination comprenant une pluralité de sources lumineuses disposées autour de l'enveloppe, la couverture étant réalisée en un matériau assurant la transmission d'au moins une partie de la lumière émise par les sources lumineuses vers l'intérieur du logement, et présentant une surface interne assurant une diffusion de la lumière transmise à l'intérieur du logement, la couverture comprenant un trou destiné à être obstrué par l'objectif d'un appareil photographique ou d'une caméra agencé(e) à l'extérieur de l'enveloppe pour effectuer une prise de vue de l'objet. The present invention relates to an illumination box, for shooting an object by means of a camera or a camera, comprising an envelope defining a housing, closed, for an object to be examined and comprising a bottom and a cover, an illumination system comprising a plurality of light sources arranged around the envelope, the cover being made of a material ensuring the transmission of at least part of the light emitted by the light sources towards the interior of the housing, and having an internal surface providing diffusion of the light transmitted inside the housing, the cover comprising a hole intended to be obstructed by the objective of a photographic device or of a camera arranged ( e) outside the envelope to shoot the object.
Etat de la technique State of the art
[0002] Des dispositifs de ce type sont déjà connus de l'état de la technique, notamment dans le but de proposer des studios photographiques facilement transportables. [0002] Devices of this type are already known from the state of the art, in particular with the aim of providing easily transportable photographic studios.
[0003] Ainsi, par exemple, la demande de brevet US 2003/0193800 A1 décrit plusieurs modes de réalisation d'une boite à illumination permettant d'illuminer de manière uniforme un objet à photographier disposé à l'intérieur de la boite. En particulier, la boite selon le mode de réalisation illustré sur les figures 6 et 7 comporte un fond surmonté d'un couvercle parallélépipédique. Plusieurs sources lumineuses sont agencées verticalement autour d'un logement central parallélépipédique délimité par une feuille de matériau diffusant la lumière. Un appareil permettant d'effectuer des prises de vue d'un objet est agencé au-dessus du logement, à l'extérieur du couvercle. L'accès à l'intérieur du logement n'est pas très clair selon ce mode de réalisation, mais ce document prévoit, dans un autre mode de réalisation (figure 5) que le couvercle soit muni d'une porte latérale offrant un accès au logement. Nous pouvons supposer que, dans le mode de réalisation des figures 6 et 7, la plaque sur laquelle est fixé l'appareil de prise de vue soit amovible, étant donné que l'agencement des sources lumineuses ne permet pas la mise en place d'une porte latérale. [0003] Thus, for example, patent application US 2003/0193800 A1 describes several embodiments of an illumination box making it possible to uniformly illuminate an object to be photographed placed inside the box. In particular, the box according to the embodiment illustrated in FIGS. 6 and 7 comprises a bottom surmounted by a parallelepipedic cover. Several light sources are arranged vertically around a central parallelepipedic housing delimited by a sheet of light-diffusing material. A device for taking shots of an object is arranged above the housing, outside the cover. Access to the interior of the housing is not very clear according to this embodiment, but this document provides, in another embodiment (Figure 5) that the cover is provided with a side door providing access to housing. We can assume that, in the embodiment of Figures 6 and 7, the plate on which the camera is fixed is removable, given that the arrangement of the light sources does not allow the installation of a side door.
[0004] Dans tous les cas, les boites présentées dans ce document ne permettent pas la mise en oeuvre d'une illumination suffisamment uniforme de l'objet à examiner pour prétendre à une qualité de prise de vue comparable à celle obtenue dans un véritable studio photographique professionnel. En effet, non seulement les sources lumineuses ne sont pas agencées de manière suffisamment régulière autour du logement, mais en outre plusieurs zones sombres sont inévitables et pourraient être décelées sur les prises de vue, en fonction de la nature de l'objet à examiner, notamment si ce dernier comporte au moins une surface réfléchissante comme c'est par exemple le cas d'une montre avec sa glace et parfois sa boite. En particulier, le fond et la ou les portes d'accès au logement constituent de telles zones sombres, aussi les faces éventuelles de l'objet à examiner orientées en direction du fond ou du dessus de la boite ne seront pas aussi bien illuminées que ses faces latérales. In all cases, the boxes presented in this document do not allow the implementation of a sufficiently uniform illumination of the object to be examined to claim a shooting quality comparable to that obtained in a real studio. professional photographer. Indeed, not only are the light sources not arranged in a sufficiently regular manner around the housing, but in addition several dark areas are inevitable and could be detected on the shots, depending on the nature of the object to be examined, in particular if the latter comprises at least one reflective surface as is for example the case of a watch with its glass and sometimes its case. In particular, the bottom and the access door(s) to the housing constitute such dark areas, so any faces of the object to be examined oriented towards the bottom or the top of the box will not be as well illuminated as its sides. side faces.
[0005] Ainsi, le besoin existe toujours de pouvoir disposer d'une boite à illumination, transportable, permettant d'obtenir une illumination uniforme d'un objet à examiner avec une qualité approchant celle obtenue en studio photographique professionnel. [0005] Thus, the need still exists to be able to have a transportable illumination box, making it possible to obtain uniform illumination of an object to be examined with a quality approaching that obtained in a professional photographic studio.
Divulgation de l'invention Disclosure of Invention
[0006] Un but principal de la présente invention est de proposer une boite à illumination de construction alternative à celle des boites déjà connues de l'art antérieur, permettant d'obtenir une qualité d'illumination supérieure à celle de ces dernières. A main object of the present invention is to provide an illumination box of alternative construction to that of the boxes already known from the prior art, making it possible to obtain a quality of illumination superior to that of the latter.
[0007] A cet effet, la présente invention concerne plus particulièrement une boite à illumination du type mentionné plus haut, caractérisée par le fait que son fond soit également réalisé en un matériau assurant la transmission d'au moins une partie de la lumière émise par les sources lumineuses vers l'intérieur du logement, et présentant une surface interne assurant une diffusion de la lumière transmise à l'intérieur du logement, et par le fait que l'enveloppe remplisse une fonction de guide de lumière sur toute son étendue pour assurer une illumination sensiblement homogène du logement. To this end, the present invention relates more particularly to an illumination box of the type mentioned above, characterized in that its bottom is also made of a material ensuring the transmission of at least part of the light emitted by the light sources towards the interior of the housing, and having an internal surface providing diffusion of the light transmitted inside the housing, and by the fact that the envelope fulfills a light guide function over its entire extent to ensure substantially homogeneous illumination of the housing.
[0008] Grâce à ces caractéristiques, la lumière émise par les sources lumineuses se propage dans toute l'enveloppe et évite l'apparition de toute zone sombre qui serait détectable lors des prises de vue de l'objet à examiner, la lumière parvenant ainsi à l'objet depuis toutes les directions. [0008] Thanks to these characteristics, the light emitted by the light sources propagates throughout the envelope and avoids the appearance of any dark zone which would be detectable when taking pictures of the object to be examined, the light thus reaching to the object from all directions.
[0009] Il peut être particulièrement avantageux de prévoir que l'interface entre le fond et la couverture soit agencée de telle manière qu'une partie de la lumière émise par les sources lumineuses puisse passer du fond à la couverture et inversement. [0009] It may be particularly advantageous to provide that the interface between the bottom and the cover be arranged in such a way that part of the light emitted by the light sources can pass from the bottom to the cover and vice versa.
[0010] En outre, il peut être encore plus avantageux de prévoir que la couverture présente une forme générale incurvée dépourvue d'arête vive. [0010] In addition, it may be even more advantageous to provide that the cover has a generally curved shape with no sharp edges.
[0011] Ainsi, l'intégralité de la surface interne de l'enveloppe apparait comme uniforme lorsqu'elle est observée depuis l'intérieur du logement, avec pour seule exception le trou de la couverture permettant d'effectuer des prises de vue depuis l'extérieur de l'enveloppe. [0011] Thus, the entire internal surface of the casing appears uniform when observed from inside the housing, with the sole exception of the hole in the cover allowing shots to be taken from the exterior of the envelope.
[0012] De manière générale, on peut préférablement prévoir que la couverture comprenne au moins une première portion mobile ou amovible, de telle manière que la couverture soit susceptible de présenter une configuration fermée, dans laquelle la portion mobile ou amovible contribue à créer une surface interne continue de la couverture, et une configuration ouverte, dans laquelle la portion mobile ou amovible dégage un passage au travers de la couverture, permettant à un utilisateur d'introduire l'objet dans le logement, de l'en extraire, et de l'y manipuler avant, pendant ou après une prise de vue. [0012] In general, provision may preferably be made for the cover to comprise at least a first mobile or removable portion, such that the cover is capable of presenting a closed configuration, in which the mobile or removable portion contributes to creating a surface continuous interior of the cover, and an open configuration, in which the movable or removable portion clears a passage through the cover, allowing a user to introduce the object into the housing, to extract it, and to handle it before, during or after a shot.
[0013] Grâce au fait que l'intégralité de l'enveloppe remplisse la fonction de guide de lumière, une partie de la lumière émise par les sources lumineuses passe à l'intérieur de la portion mobile ou amovible lorsqu'elle est en place dans la couverture, évitant ainsi qu'elle ne crée une zone sombre comme c'est typiquement le cas dans les dispositifs antérieurs. [0014] Selon une variante de réalisation, on peut prévoir que la couverture comprenne au moins une deuxième portion mobile ou amovible similaire à la première portion mobile ou amovible, permettant ainsi à un utilisateur de manipuler un objet à l'intérieur du logement avec ses deux mains avant, pendant ou après une prise de vue. [0013] Thanks to the fact that the entire envelope fulfills the function of a light guide, part of the light emitted by the light sources passes inside the mobile or removable portion when it is in place in the cover, thus preventing it from creating a dark zone as is typically the case in prior devices. [0014]According to a variant embodiment, provision may be made for the cover to comprise at least a second mobile or removable portion similar to the first mobile or removable portion, thus allowing a user to manipulate an object inside the housing with its two hands before, during or after a shot.
[0015] De manière générale, on peut prévoir que le fond comprenne une portion périphérique fixe en référence à la couverture et présentant un trou circulaire dans lequel est agencée une portion centrale en forme de disque, définissant un plateau tournant et susceptible d'être entraînée en rotation depuis l'extérieur de l'enveloppe, les portions périphérique et centrale étant agencées et dimensionnées l'une relativement à l'autre de manière à définir une surface interne continue du fond et de telle manière qu'une partie de la lumière émise par les sources lumineuses puisse passer de l'une à l'autre. In general, provision can be made for the bottom to comprise a fixed peripheral portion with reference to the cover and having a circular hole in which is arranged a central disc-shaped portion, defining a turntable and capable of being driven in rotation from the outside of the envelope, the peripheral and central portions being arranged and dimensioned relative to each other so as to define a continuous internal surface of the bottom and in such a way that a part of the light emitted by the light sources can switch from one to the other.
[0016] Grâce à ces caractéristiques, l'objet peut être déplacé à l'intérieur du logement tout en maintenant des conditions d'illumination optimales. [0016] Thanks to these characteristics, the object can be moved inside the housing while maintaining optimal lighting conditions.
[0017] Par ailleurs, on peut également prévoir que les sources lumineuses soient réparties de manière sensiblement régulière autour de la couverture, et qu'au moins une source lumineuse soit agencée sur au moins un côté du fond pour émettre directement de la lumière dans le fond. Au moins une source lumineuse peut également être agencée sous le fond pour réaliser un rétro-éclairage de l'objet à examiner s! nécessaire. [0017] Furthermore, provision can also be made for the light sources to be distributed in a substantially regular manner around the cover, and for at least one light source to be arranged on at least one side of the bottom to emit light directly into the bottom. At least one light source can also be arranged under the bottom to provide backlighting of the object to be examined! necessary.
[0018] De manière générale, on peut prévoir que la boite selon l'invention comprenne une coque de protection agencée autour de la couverture, à distance suffisante de cette dernière pour définir un espace dans lequel est agencée au moins une partie des sources lumineuses, la coque présentant une fenêtre sensiblement alignée avec le trou de la couverture par lequel les prises de vue peuvent être réalisées. In general, it is possible to provide that the box according to the invention comprises a protective shell arranged around the cover, at a sufficient distance from the latter to define a space in which is arranged at least part of the light sources, the shell having a window substantially aligned with the hole in the cover through which shots can be taken.
[0019] Dans ce cas, on peut avantageusement prévoir que la coque porte un support pour un appareil photographique, un smartphone, une tablette ou une caméra. [0019] In this case, it is advantageous to provide for the shell to carry a support for a camera, a smartphone, a tablet or a camera.
[0020] De manière générale, on peut prévoir que la boite comporte un dispositif de commande des sources lumineuses permettant d'ajuster les propriétés de la lumière émise par ces dernières, notamment son intensité et sa température. De manière préférée, les sources lumineuses peuvent être contrôlées individuellement et/ou par groupes. [0020] In general, provision can be made for the box to include a device for controlling the light sources making it possible to adjust the properties of the light emitted by the latter, in particular its intensity and its temperature. Preferably, the light sources can be controlled individually and/or in groups.
[0021] On peut également prévoir que la boite comporte un dispositif de commande à distance d'un appareil photographique, d'un smartphone, d'une tablette ou d'une caméra, notamment pour déclencher une prise de vue. [0021] It is also possible for the box to include a remote control device for a camera, a smartphone, a tablet or a camera, in particular for triggering a shot.

Mode(s) de réalisation de l'invention Embodiment(s) of the Invention
[0023] La figure 1 représente une vue en perspective simplifiée d'une boite à illumination 1 selon un mode de réalisation préféré de la présente invention. Figure 1 shows a simplified perspective view of an illumination box 1 according to a preferred embodiment of the present invention.
[0024] Une telle boite à illumination peut présenter des utilisations multiples. En effet, non seulement elle peut être destinée à la réalisation de prises de vue, au moyen d'un appareil photographique (éventuellement celui d'un smartphone ou d'une tablette) ou d'une caméra, d'un objet de dimensions limitées, à titre d'exemple illustratif non limitatif d'une montre ou d'un bijou, en évitant de transporter l'objet à examiner jusqu'à un studio photographique professionnel où, notamment, la mise en place d'un éclairage adapté à un objet particulier peut être complexe. Bien entendu, si la qualité d'illumination de l'objet à examiner ne sera pas exactement la même que dans un vrai studio photographique, elle s'en approchera le plus possible. Par ailleurs, une telle boite à illumination peut également être utilisée pour présenter un objet à une personne distante par retransmission des images d'une caméra au travers d'une connexion internet. [0024] Such an illumination box can have multiple uses. Indeed, not only can it be intended for taking pictures, by means of a camera (possibly that of a smartphone or a tablet) or a camera, of an object of limited dimensions , by way of non-limiting illustrative example of a watch or piece of jewelry, by avoiding transporting the object to be examined to a professional photographic studio where, in particular, the installation of lighting adapted to a particular object can be complex. Of course, if the quality of illumination of the object to be examined will not be exactly the same as in a real photographic studio, it will approach it as closely as possible. Moreover, such an illumination box can also be used to present an object to a remote person by retransmission of images from a camera through an Internet connection.
[0025] Comme cela ressortira de la description qui va suivre, la boite à illumination 1 selon la présente invention se prête parfaitement bien à ces différentes utilisations. As will emerge from the following description, the illumination box 1 according to the present invention lends itself perfectly well to these different uses.
[0026] Il apparait de la figure 1 que la boite à illumination 1 comporte un fond 2 revêtu d'une couverture 4, elle-même surmontée d'une coque 6. La distance entre la couverture 4 et la coque 6 est suffisante pour définir un espace dans lequel des sources lumineuses 8 sont agencées, celles-ci étant illustrées sur la figure 1 sous la forme de bande de LEDs à titre non limitatif. It appears from Figure 1 that the illumination box 1 comprises a bottom 2 covered with a cover 4, itself surmounted by a shell 6. The distance between the cover 4 and the shell 6 is sufficient to define a space in which light sources 8 are arranged, the latter being illustrated in FIG. 1 in the form of strips of LEDs without limitation.
[0027] Le fond 2 et la couverture 4 forment ensemble une enveloppe délimitant un logement 10 dans lequel peut être positionné un objet à examiner, notamment duquel des prises de vue doivent être réalisées au moyen d'un appareil photographique ou d'une caméra. The bottom 2 and the cover 4 together form an envelope delimiting a housing 10 in which can be positioned an object to be examined, in particular of which shots must be taken by means of a camera or a camera.
[0028] Ainsi, la couverture 4 est réalisée en un matériau laissant passer une grande partie de la lumière émise par les sources lumineuses 8 et présentant au moins une surface interne assurant une diffusion de la lumière vers l'intérieur du logement 10. A titre d'exemple non limitatif, la couverture 4 peut être réalisée en plexiglas dont au moins la face interne est dépolie ou sablée. L'homme du métier pourra choisir tout autre matériau adapté sans sortir du cadre de l'invention. Thus, the cover 4 is made of a material allowing a large part of the light emitted by the light sources 8 to pass and having at least one internal surface providing diffusion of the light towards the interior of the housing 10. As by non-limiting example, the cover 4 can be made of Plexiglas of which at least the internal face is frosted or sandblasted. A person skilled in the art may choose any other suitable material without departing from the scope of the invention.
[0029] De manière avantageuse, la couverture 4 remplit un rôle de guide de lumière: la lumière émise par les sources lumineuses 8 qui entre dans la couverture 4 se propage dans toute son étendue pour ressortir de manière sensiblement uniforme dans le logement 10 en étant diffusée. [0029] Advantageously, the cover 4 fulfills the role of a light guide: the light emitted by the light sources 8 which enters the cover 4 spreads over its entire extent to emerge in a substantially uniform manner in the housing 10 by being broadcast.
[0030] Selon le mode de réalisation préféré qui est illustré sur la figure 1 , la couverture 4 de la boite à illumination 1 comprend deux portions mobiles ou amovibles (non représentées) dont chacune présente une forme complémentaire à celle d'une ouverture latérale 12 définissant un passage au travers de la couverture 4, permettant à un utilisateur d'introduire l'objet à examiner dans le logement 10, de l'en extraire et de l'y manipuler. Ainsi, chaque portion mobile ou amovible remplit la fonction d'une porte permettant d'enfermer complètement l'objet à examiner dans le logement 10. [0030] According to the preferred embodiment which is illustrated in Figure 1, the cover 4 of the illumination box 1 comprises two movable portions or removable (not shown) each of which has a shape complementary to that of a side opening 12 defining a passage through the cover 4, allowing a user to introduce the object to be examined into the housing 10, from extract and manipulate it there. Thus, each movable or removable portion fulfills the function of a door making it possible to completely enclose the object to be examined in the housing 10.
[0031] Conformément aux caractéristiques de la présente invention, chaque portion mobile ou amovible est réalisée en un matériau optiquement compatible avec celui du reste de la couverture 4 (c'est-à-dire ici présentant un indice de réfraction similaire voire identique), préférablement le même matériau, et présente sensiblement la même épaisseur que le reste de la couverture 4. Ainsi, lorsque les portions mobiles ou amovibles sont positionnées dans les ouvertures 12, correspondant à une configuration fermée de la couverture 4, elles définissent une surface interne continue avec le reste de la couverture 4, tandis que la lumière transitant dans le reste de la couverture 4 peut être transmise à l'intérieur des portions mobiles ou amovibles et inversement. Grâce à ces caractéristiques, la boite à illumination 1 peut comporter une ou plusieurs portes d'accès à son logement 10 sans pour autant présenter des zones sombres comme c'est le cas avec les dispositifs de l'art antérieur. In accordance with the characteristics of the present invention, each movable or removable portion is made of a material optically compatible with that of the rest of the cover 4 (that is to say here having a similar or even identical refractive index), preferably the same material, and has substantially the same thickness as the rest of the cover 4. Thus, when the movable or removable portions are positioned in the openings 12, corresponding to a closed configuration of the cover 4, they define a continuous internal surface with the rest of the cover 4, while the light passing through the rest of the cover 4 can be transmitted inside the mobile or removable portions and vice versa. Thanks to these characteristics, the illumination box 1 can comprise one or more access doors to its housing 10 without however presenting dark areas as is the case with the devices of the prior art.
[0032] Les portions mobiles ou amovibles peuvent être retenues en place dans les ouvertures 12 par tout moyen adapté sans sortir du cadre de la présente invention, notamment par des charnières positionnées à l'extérieur de l'enveloppe, ou par mise en oeuvre d'au moins une languette ou d'un rebord adapté ménagé(e) sur la périphérie extérieure de la portion mobile ou amovible, destiné(e) à prendre appui sur la surface externe de la couverture 4, autour des ouvertures 12. The movable or removable portions can be retained in place in the openings 12 by any suitable means without departing from the scope of the present invention, in particular by hinges positioned outside the envelope, or by implementing at least one tab or a suitable rim made on the outer periphery of the movable or removable portion, intended to rest on the outer surface of the cover 4, around the openings 12.
[0033] Enfin, toujours selon les caractéristiques de la présente invention, le fond 2 est également réalisé en un matériau optiquement compatible avec celui de la couverture 4, préférablement le même matériau. Ainsi, l'interface entre le fond 2 et la couverture 4 permet à la lumière de passer librement de l'un à l'autre et permet au fond 2 de contribuer à l'illumination du logement 10. De manière générale, cette caractéristique permet également la mise en œuvre d'un rétro-éclairage, si nécessaire, en disposant au moins une source lumineuse sous le fond 2. Finally, still according to the characteristics of the present invention, the bottom 2 is also made of a material optically compatible with that of the cover 4, preferably the same material. Thus, the interface between the bottom 2 and the cover 4 allows light to pass freely from one to the other and allows the bottom 2 to contribute to the illumination of the housing 10. Generally, this characteristic also allows the implementation of backlighting, if necessary, by arranging at least one light source under the bottom 2.
[0034] Par ailleurs, on peut avantageusement prévoir que la coque 6 soit réalisée en un matériau opaque, non seulement pour une question de confort de l'utilisateur, évitant de l'éblouir, mais également pour retenir un maximum de lumière à l'intérieur de la boite à illumination 1. [0034] Furthermore, it is advantageous to provide that the shell 6 is made of an opaque material, not only for a question of user comfort, avoiding dazzling it, but also to retain as much light as possible. interior of light box 1.
[0035] Les figures 2 et 3 représentent respectivement des vues latérale et en perspective partielles simplifiées de la boite à illumination 1 , permettant de mieux en comprendre certains détails de construction. [0035] Figures 2 and 3 show respectively simplified partial side and perspective views of the illumination box 1, allowing a better understanding of certain construction details.
[0036] On constate sur les vues des figures 2 et 3 que les sources lumineuses 8 sont régulièrement réparties tout autour de la couverture 4 pour garantir l'uniformité de l'illumination dans le logement 10. It can be seen in the views of Figures 2 and 3 that the light sources 8 are regularly distributed all around the cover 4 to guarantee the uniformity of the illumination in the housing 10.
[0037] De plus, il apparait de ces mêmes figures qu'une source lumineuse 8 est également agencée contre une tranche du fond 2 afin que ce dernier puisse activement contribuer à l'illumination du logement 10. Comme mentionné plus haut, au moins une source lumineuse 8 peut être agencée sous le fond (non illustrée) pour permettre la mise en œuvre d'un rétro-éclairage de l'objet à examiner. In addition, it appears from these same figures that a light source 8 is also arranged against an edge of the bottom 2 so that the latter can actively contribute to the illumination of the housing 10. As mentioned above, at least one light source 8 can be arranged under the bottom (not shown) to allow the implementation of backlighting of the object to be examined.
[0038] L'homme du métier ne rencontrera pas de difficulté particulière pour agencer des sources lumineuses 8 autour du fond 2 d'une manière adaptée à ses propres besoins, sans pour autant sortir du cadre de la présente invention tel qu'il est défini par le jeu de revendications annexé. Ainsi, il est par exemple possible de disposer une source lumineuse 8 sur au moins chacun des petits côtés du fond 2 ou sur au moins chacun de ses grands côtés et/ou sous le fond 2, voire d'utiliser une seule bande de LEDs souple pour l'agencer tout autour du fond 2. [0038] Those skilled in the art will not encounter any particular difficulty in arranging light sources 8 around the bottom 2 in a manner suited to their own needs, without however departing from the scope of the present invention as it is defined. by the attached set of claims. Thus, it is for example possible to arrange a light source 8 on at least each of the short sides of the bottom 2 or on at least each of its long sides and/or under the bottom 2, or even to use a single strip of flexible LEDs to arrange it all around the bottom 2.
[0039] Grâce à cette caractéristique, le fond 2 transmet activement de la lumière dans le logement 10, ce qui permet en outre de masquer complètement les jonctions entre le fond 2 et la couverture 4 dans la mesure où ces dernières sont également lumineuses, comme tout le reste de l'enveloppe. [0039] Thanks to this characteristic, the bottom 2 actively transmits light into the housing 10, which also makes it possible to completely mask the junctions between the bottom 2 and the cover 4 insofar as the latter are also luminous, as all the rest of the envelope.
[0040] Ainsi, l'ensemble de l'enveloppe se comporte comme un guide de lumière, sur toute son étendue, c'est-à-dire à la fois au niveau de la couverture 4, du fond 2 et de l'interface entre ces deux éléments, donnant lieu à une illumination continue et uniforme de bien meilleure qualité qu'avec les dispositifs de l'art antérieur. [0040] Thus, the whole of the envelope behaves like a light guide, over its entire extent, that is to say both at the level of the cover 4, of the bottom 2 and the interface between these two elements, giving rise to a continuous and uniform illumination of much better quality than with the devices of the prior art.
[0041] On notera que la couverture 4 présente ici avantageusement une forme générale incurvée dépourvue d'arête vive pour permettre d'optimiser au maximum l'uniformité de l'illumination dans le logement 10. [0041] It will be noted that the cover 4 here advantageously has a curved general shape devoid of any sharp edge to allow the uniformity of the illumination in the housing 10 to be optimized as much as possible.
[0042] Pour ce qui concerne la mise en place de l'appareil pour réaliser les prises de vue, plusieurs solutions sont envisageables tout en restant dans le cadre de la présente invention. Il est possible d'agencer une caméra 14 dans l'espace situé entre la couverture 4 et la coque 6 (figures 1 et 2) ou, en alternative, une caméra, un appareil photographique, un smartphone ou une tablette peut être mis(e) en place à l'extérieur de la coque 6. As regards the installation of the apparatus for taking the shots, several solutions are possible while remaining within the scope of the present invention. It is possible to arrange a camera 14 in the space located between the cover 4 and the shell 6 (FIGS. 1 and 2) or, alternatively, a camera, a camera, a smartphone or a tablet can be placed ) in place outside the hull 6.
[0043] La couverture 4 comprend ainsi un trou 16 permettant de réaliser des prises de vue depuis l'extérieur de l'enveloppe délimitant le logement 10. The cover 4 thus comprises a hole 16 allowing shots to be taken from outside the envelope delimiting the housing 10.
[0044] Lorsqu'un appareil doit être agencé à l'extérieur de la coque 6, cette dernière est également pourvue d'une fenêtre (non visible) située sensiblement en alignement avec le trou 16 de la couverture 4. When a device must be arranged outside the shell 6, the latter is also provided with a window (not visible) located substantially in alignment with the hole 16 of the cover 4.
[0045] Dans le cas où un appareil externe est utilisé, un support 18 adapté peut être prévu sur la coque 6, comme illustré sur la figure 3, s'agissant ici d'un support pour smartphone. [0045] In the case where an external device is used, a suitable support 18 can be provided on the shell 6, as illustrated in FIG. 3, here being a support for a smartphone.
[0046] Par ailleurs, on peut prévoir que la boite à illumination 1 comporte un dispositif 20 de commande des sources lumineuses 8 agencé dans le logement 10, voire éventuellement amovible de manière analogue à une télécommande. Ainsi, ce dispositif 20 peut notamment permettre d'ajuster les propriétés de la lumière émise par les sources lumineuses 8, comme par exemple son intensité et/ou sa température. Comme déjà mentionné, les sources lumineuses 8 peuvent préférablement être contrôlées individuellement et/ou par groupes associés à différentes zones de l'enveloppe, notamment leur puissance. Furthermore, provision can be made for the illumination box 1 to comprise a device 20 for controlling the light sources 8 arranged in the housing 10, or possibly even removable in a manner analogous to a remote control. Thus, this device 20 can in particular make it possible to adjust the properties of the light emitted by the light sources 8, such as for example its intensity and/or its temperature. As already mentioned, the light sources 8 can preferably be controlled individually and/or in groups associated with different areas of the envelope, in particular their power.
[0047] En outre, il est possible de prévoir que le dispositif 20 de commande permette également de commander à distance un appareil de prise de vue, comme un appareil photographique, une caméra, un smartphone ou une tablette. En alternative, il est possible de prévoir la mise en oeuvre d'un dispositif de commande supplémentaire spécifique à l'appareil de prise de vue. In addition, it is possible to provide that the control device 20 also makes it possible to remotely control a shooting device, such as a camera, a camera, a smartphone or a tablet. Alternatively, it is possible to provide for the implementation of a camera-specific additional control device.
[0048] Enfin, une caractéristique supplémentaire optionnelle peut avantageusement être mise en oeuvre dans le logement 10, à savoir le fait de prévoir un plateau tournant 22 situé sensiblement au centre du logement 10. A cet effet, le fond 2 peut comprendre une portion périphérique 24 fixe en référence à la couverture 4 et présentant un trou circulaire dans lequel est agencé une portion centrale en forme de disque définissant le plateau tournant 22. Différents mécanismes d'entrainement en rotation du plateau tournant 22 peuvent être prévus tout en restant dans le cadre de la présente invention. De manière avantageuse, on peut prévoir qu'une plaque transparente (non visible) soit rendue solidaire du plateau tournant 22 en étant située à l'extérieur du logement 10. Ainsi, cette plaque transparente serait manipulable par un utilisateur depuis l'extérieur du logement, pour faire tourner le plateau tournant 22 et donc l'objet à examiner, sans pour autant créer de zone sombre sous le plateau tournant 22. Finally, an optional additional feature can advantageously be implemented in the housing 10, namely the fact of providing a turntable 22 located substantially in the center of the housing 10. For this purpose, the bottom 2 may comprise a peripheral portion 24 fixed with reference to the cover 4 and having a circular hole in which is arranged a central disc-shaped portion defining the turntable 22. Different mechanisms for driving the turntable 22 in rotation can be provided while remaining within the framework of the present invention. Advantageously, provision can be made for a transparent plate (not visible) to be made integral with the turntable 22 by being located outside the housing 10. Thus, this transparent plate would be manipulated by a user from outside the housing. , to rotate the turntable 22 and therefore the object to be examined, without creating a dark zone under the turntable 22.
[0049] Les figures 4, 5 et 6 représentent des vues respectives, en perspective, partielle de dessus et en perspective avec masquage partiel, simplifiées d'une boite d'illumination 100 selon une variante de réalisation du mode préféré de la présente invention. FIGS. 4, 5 and 6 represent respective views, in perspective, partial from above and in perspective with partial masking, simplified, of an illumination box 100 according to an alternative embodiment of the preferred mode of the present invention.
[0050] Les mêmes composants que ceux décrits en relation avec les figures 1 à 3 portent les mêmes références numériques dans un souci de simplicité. The same components as those described in relation to Figures 1 to 3 bear the same reference numerals for the sake of simplicity.
[0051] La boite à illumination 100 se distingue simplement de la boite à illumination 1 par sa forme générale en dôme. The illumination box 100 is simply distinguished from the illumination box 1 by its general domed shape.
[0052] La boite à illumination 100 est présentée sur les figures 4 à 6 dans sa variante comprenant une caméra interne 14, agencée dans l'espace entre la couverture 4 et la coque 6. The illumination box 100 is shown in Figures 4 to 6 in its variant comprising an internal camera 14, arranged in the space between the cover 4 and the shell 6.
[0053] On constate que des sources lumineuses 8 souples sont utilisées pour qu'elles puissent épouser autant que possible la courbure de la couverture 4. [0053] It can be seen that flexible light sources 8 are used so that they can match the curvature of the cover 4 as much as possible.
[0054] Cette forme de dôme permet notamment la réalisation d'une boite à illumination plus compacte que celle illustrée sur les figures 1 à 3. [0055] L'homme du métier ne rencontrera pas de difficulté particulière à adapter le présent enseignement pour réaliser une boite à illumination présentant une forme différente de celles présentées ici à titre illustratif non limitatif sans sortir du cadre de l'invention tel que défini dans le jeu de revendications annexé. De plus, il est possible de prévoir un grand nombre d'agencements différents pour les sources lumineuses sans sortir du cadre de l'invention, notamment pour prendre en compte la forme de l'enveloppe. Par ailleurs, il est également possible de prévoir l'agencement d'au moins une source lumineuse sous le fond de la boite pour réaliser un rétro-éclairage de l'objet à examiner en cas de besoin. This dome shape allows in particular the production of a more compact illumination box than that illustrated in Figures 1 to 3. [0055] The person skilled in the art will not encounter any particular difficulty in adapting this teaching to produce an illumination box having a shape different from those presented here by way of non-limiting illustration without departing from the scope of the invention as defined in the attached set of claims. In addition, it is possible to provide a large number of different arrangements for the light sources without departing from the scope of the invention, in particular to take into account the shape of the envelope. Furthermore, it is also possible to provide the arrangement of at least one light source under the bottom of the box to provide backlighting of the object to be examined if necessary.
[0056] Grâce aux caractéristiques qui viennent d'être décrites, il est possible de réaliser une boite à illumination pour effectuer la prise de vue de différents objets dans des conditions d'illumination très proches de celles qu'il est possible d'obtenir dans un vrai studio photographique professionnel. En outre, une telle boite à illumination présente une grande souplesse d'utilisation et permet également de présenter un objet à une personne distante dans d'excellentes conditions de visibilité. [0056] Thanks to the characteristics which have just been described, it is possible to produce an illumination box for taking pictures of different objects under illumination conditions very close to those which it is possible to obtain in a true professional photographic studio. In addition, such an illumination box has great flexibility of use and also makes it possible to present an object to a distant person in excellent conditions of visibility.
[0057] La description qui précède s'attache à décrire un mode de réalisation particulier à titre d'illustration non limitative et, l'invention n'est pas limitée à la mise en oeuvre de certaines caractéristiques particulières qui viennent d'être décrites, comme par exemple la forme de la boite à illumination illustrée et décrite, ou encore la matière dans laquelle ses différents constituants sont réalisés ou la nature des sources lumineuses utilisées. The foregoing description sets out to describe a particular embodiment by way of non-limiting illustration and, the invention is not limited to the implementation of certain particular characteristics which have just been described, such as for example the shape of the illumination box illustrated and described, or even the material in which its various constituents are made or the nature of the light sources used.
