Definitions
- the invention relates to the field of luminaires, and more particularly to the field of longitudinal luminaires, in particular, but not exclusively, for industrial applications, for example in an explosive environment.
- One embodiment relates to a longitudinal luminaire comprising a cylindrical casing extending in a longitudinal direction, said casing being at least partly transparent, and a lighting device arranged inside the casing, in which the lighting device and the housing are assembled using only a plurality of brackets.
- the casing is an outer casing which forms an envelope receiving the lighting device and isolates it from the external environment.
- the housing has a cylindrical shape, the section of which transverse to the longitudinal direction may be circular, but not necessarily.
- the casing has the shape of a profile, open at its two longitudinal ends.
- the casing is wholly or partly transparent so as to allow the light emitted by the lighting device to pass.
- the casing is entirely transparent. Only one longitudinal end of the housing can be open, or both longitudinal ends are open.
- a plurality of brackets that is to say at least two brackets, make it possible to assemble the lighting device to the housing, the lighting device being housed within the housing.
- the lighting device is mounted within the housing via the brackets.
- the lighting device is mounted on the brackets, which themselves are mounted on the housing. Consequently, the lighting device is mounted on the housing by means of the brackets only.
- Such an assembly has a simple structure, having a reduced number of parts, which is therefore easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust.
- the brackets are fixed to the housing by bolting or the like (i.e. by bolting means or the like).
- brackets or equivalent is meant any method of fixing which makes it possible to assemble the brackets to the casing by passing through the wall of the casing, for example using a bolt, a screw, a rivet, etc. .
- each bracket is therefore fixed to the casing via at least one hole made in the wall of the casing.
- each bracket is bolted to the housing via a single hole.
- each bracket is fixed to the housing via two holes, one hole serving for bolting or equivalent of said bracket, the other hole serving to block the bracket in rotation via a locking cleat.
- each bracket is fixed to the casing via two holes, each of the two holes serving for bolting or the equivalent of said bracket.
- each bracket is fixed to the housing via two holes, these holes being less than 5.0 cm (five centimeters) apart in the longitudinal direction. Such a spacing between the holes is not or very little modified during the thermal expansion of the casing when the luminaire is lit or when it is placed in a particularly hot environment (and therefore does not generate any additional mechanical stress), while the fixing of the brackets to the casing via two holes is satisfactory.
- the assembly structure of the luminaire is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable. and robust.
- the housing is made of glass or a polymeric material.
- the polymeric material is polycarbonate (also known by the acronym "PC)” or polymethyl methacrylate (also known by the acronym "PMMA”). More generally, the polymeric material is for example a synthetic organic polymeric material or synthetic organic polymer.
- the glass and the polymeric material are resistant both from a mechanical and thermal point of view, and have, of course in transparent form, very good light transmission properties. Furthermore, such materials can be drilled for the assembly of brackets by bolting or the like without being damaged.
- the polymeric material also has the advantage of being particularly light, which facilitates its handling and allows the use of less robust and therefore less expensive fasteners.
- the casing has a circular cross-section (in the longitudinal direction), each bracket comprising a lug for locking the lighting device in rotation around the axis of the casing.
- the casing having a circular cross section, it has a symmetry of revolution and has an axis of revolution parallel to the longitudinal direction, this axis being called the axis of the casing.
- each bracket is particularly easy to implement, and does not impose any direction of assembly. Furthermore, by equipping each bracket with a rotational locking lug, the lighting device within the casing is maintained in position around the axis of the casing, in all circumstances.
- the blocking effected by the lug is a relative blocking between the square and the lighting device. In other words, the lug blocks the lighting device relative to the square.
- each lug forms one and the same part with a square.
- the lugs are separate elements from the bolting means or the like for assembling the bracket to the housing.
- the structure of the luminaire is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust. .
- the lighting device includes a longitudinally extending support including a pair of grooves (or first grooves) extending longitudinally, the lug of each square being engaged in a groove (or first groove).
- the support has the shape of a section, and is used for mounting the lighting device on the brackets.
- a support may for example have other functions than the mounting of the lighting device on the brackets, such as for example forming a cover to hide the parts such as the power supply and the cables of the lighting device, and / or forming a reflector to reflect light towards a predetermined direction.
- the support is made of a material of the same nature as the casing, whereby thermal expansion differentials are avoided.
- each bracket comprises at least one stop for locking the lighting device in translation in the longitudinal direction.
- each bracket comprises one or more stops, the lighting device cooperating in abutment in the longitudinal direction with one, several or even with all the brackets.
- the blocking effected by the stop (s) is a relative blocking between the square and the lighting device.
- the stop (s) block (s) the lighting device relative to the square.
- each stop forms one and the same part with a square.
- the stops are separate elements from the bolting or equivalent means for assembling the bracket to the housing.
- the stops are also separate elements from the lugs for locking the lighting device in rotation around the axis of the housing.
- the lighting device is held in position in the longitudinal direction within the casing.
- These stops being formed on the brackets, the structure of the luminaire is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust.
- the lighting device comprises a plate, the plate comprising at least one tab cooperating in abutment with the at least one abutment of a square.
- the plate is the part of the lighting device which carries the power supply, the cables and the bulbs or equivalent of the lighting device.
- bulb or equivalent is meant any lighting element such as a bulb, a fluorescent tube, a neon tube, one or more light-emitting diodes (or LED), etc.
- the tongue of the plate cooperates with one or more stops of a square.
- the tongue may have a cutout receiving said stop so as to cooperate with the stop in the two opposite directions in the longitudinal direction.
- the tongue is disposed between the two stops so as to cooperate in abutment in one direction in the longitudinal direction with each of the stops. Thanks to the tongue of the plate and the stop of the square, the structure of the luminaire is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust.
- the support comprises a pair of second grooves, these second grooves being opposite each other, the plate being mounted on the support by being inserted in the second grooves.
- the tubular luminaire comprises four brackets, two brackets being mounted on each end portion of the casing being disposed opposite each other.
- Such a symmetrical arrangement of the brackets makes it possible to mount the lighting device within the casing independently of the direction and of the relative orientation between the lighting device and the casing.
- Such a structure is simple, has a reduced number of parts, is easy to assemble and has a reduced cost of manufacture and assembly while being reliable and robust.
- the longitudinal luminaire includes a seal fitted onto each end portion. of the casing, each seal having a groove receiving one end of the casing and at least one cutout receiving a square.
- end portion is meant a portion of the casing which extends from a longitudinal end of the casing over a maximum of 20% of the length of the casing in the longitudinal direction. It will be understood that each end portion of the housing in the longitudinal direction is engaged in a groove of a seal.
- the seal covers the inside, the outside and the face perpendicular to the longitudinal direction of the end portion of the housing.
- the seal has, on its internal part arranged inside the casing as many cutouts as there are squares arranged on the end portion in question, thanks to which the squares do not interact with the seal and do not interfere with correct operation. of the seal.
- the portion of the seal which covers the outside of the casing has concavities receiving the heads of the bolts or the like, whereby the seal covers said heads without the extra thickness that represent the heads does not interfere with the proper functioning of the gasket, thus ensuring the tightness of the luminaire at the level of the holes in the housing for fixing the brackets.
- Such a single seal on each end of the casing makes it possible to ensure both a seal at the level of the end face of the casing and of the longitudinal faces of the casing.
- one or more clamps can cooperate with the seal, thus participating in the sealing provided by the seal.
- such a clamp can also serve as a fixing element for fixing the luminaire for example to a wall bracket or directly to a wall. Thanks to such a single seal on each free end of the housing, the structure of the luminaire is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust.
- the luminaire comprises a cover mounted on one end of the housing, the cover being fixed to at least one bracket.
- the cover closes an open longitudinal end of the housing.
- the casing has at least one open longitudinal end for mounting the device therein. lighting.
- At least one bracket has a fixing lug for fixing the cover mounted on the housing. The fixing is carried out for example by screwing on the tab.
- the brackets perform several functions, namely the assembly of the lighting device with the housing and the fixing of the cover on the housing.
- Such a cover can also cooperate with the optional seal, thus participating in the sealing provided by said seal. Thanks to such brackets, the structure of the luminaire is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust.
- all the brackets are the same, which further simplifies the structure and mounting of the luminaire.
- the lighting device comprises at least one switch which cooperates with the cover when the cover is mounted on the housing.
- the switch when the cover is mounted on the housing, the switch is configured to supply the lighting device with electric current from the mains, while when the cover is not assembled to the housing, the switch is configured to isolate the lighting device from the mains.
- a switch allows the operator to intervene on the luminaire, for example to replace a bulb or equivalent, in complete safety and without having to cut off the mains current.
- the at least one switch is retracted by a cover while being able to cooperate with the cover when the cover is mounted on the housing. This increases the protection of the operator in the event of an intervention and prevents him from activating the switch inadvertently.
- the power supply and the cables are also retracted. This also strengthens the protection of the operator.
- the direct cooperation between the cover and the switch contributes to the simplicity of the structure of the luminaire, which thus has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable. and robust.
- the figures 1 to 4 show an embodiment of the longitudinal luminaire according to the invention.
- the longitudinal luminaire 10 is assembled.
- the luminaire 10 extends in the longitudinal direction X.
- the luminaire 10 is described in more detail with reference to figures 2 to 4 .
- the luminaire 10 comprises a casing 12 in which is housed a lighting device 14.
- the casing 12 is transparent, and has the shape of a cylindrical section of circular section with an axis parallel to the longitudinal direction X, and open at its two ends.
- longitudinal 12aa Several brackets 16, in this example four brackets 16, make it possible to assemble the lighting device 14 with the casing 12, inside the casing 12.
- the bracket 16 comprises a fixing portion 16a, in the form of a plate extending in the longitudinal direction X , and having two tapped holes for fixing the bracket 16 on the housing 12, using screws 18.
- Two tabs 16b and 16c extend perpendicular to the fixing portion 16a, on either side of the fixing portion 16a in the longitudinal direction X.
- the tabs 16b and 16c have substantially the shape of a plate extending perpendicularly to the longitudinal direction X.
- the first tab 16b has a threaded hole for fixing a cover described later.
- the second tab 16c carries a lug 16d extending parallel to the fixing portion 16a, opposite the fixing portion 16a with respect to the tab 16c.
- a lug 16d extending parallel to the fixing portion 16a, opposite the fixing portion 16a with respect to the tab 16c.
- the two stops 16e are spaced apart and so as to delimit a window 16f.
- each bracket 16 is fixed using two screws 18 arranged in the longitudinal direction X with respect to one another. More particularly, two brackets 16 are fixed on each end portion 12a of the casing 12, inside the casing 12 and facing each other. In other words, the brackets 16 are arranged two by two diametrically opposed. In addition, the brackets 16 are aligned two by two in the longitudinal direction X. Furthermore, the brackets 16 are arranged so that the lugs 16d extend towards the inside of the housing 12 in the longitudinal direction X while the tabs 16b are arranged towards the outer side of the casing 12 in the longitudinal direction X.
- the lighting device 14 comprises a support 22 and a plate 24.
- the support 22 has the shape of a section extending in the longitudinal direction X, and has a substantially semi-circular cross section, and thus forms a half portion. -circular 22a. Grooves are formed at the ends of the semi-circular section, thus forming grooves extending in the longitudinal direction X. Thus, two first grooves 22b are oriented towards the outside of the semi-circular portion 22a while two second grooves 22c are oriented towards the interior of the semicircular portion 22a. Each end of the semicircular section has a single first groove 22b and a single second groove 22c. In this example, the grooves 22b and 22c are oriented radially with respect to the semicircular shape 22a.
- the plate 24 has a shape substantially of a plate extending longitudinally and having longitudinal edges 24a. Fluorescent tubes 25 and their mounting terminals are arranged on a first side of the plate 24 while the power supply and the power cables (not shown) of the fluorescent tubes 25 are arranged on a second side, opposite to the first side, of the plate 24.
- the plate 24 is mounted on the support 22 by inserting the longitudinal edges 24a in the second grooves 22c. The second grooves 22c thus form a slideway receiving the plate 24.
- the plate 24 is mounted on the support 22 so that the fluorescent tubes 25 are visible while the power supply and the cables, not shown, are on the side of the support 22 and therefore retracted.
- the support 22 forms a cover which enables the power supply and the cables to be retracted, thus ensuring an aesthetic function.
- the inner surface 22aa of the semi-circular portion 22a is reflective.
- the support 22 also forms a reflector making it possible to optimize the light flux emitted by the luminaire 10, by reflecting the light emitted by the fluorescent tubes 25.
- the support 22 is placed inside the casing 12 by engaging the lug 16d of each bracket 16 in a first groove 22b.
- the windows 16f of the brackets 16 have the same width as the second grooves 22c.
- the lighting device 14, and more particularly in this example the support 22, is thus carried and locked in rotation around the axis of the housing 12 by the lugs 16d. Furthermore, the lighting device 14, and more particularly in this example the support 22, cooperates in abutment in the longitudinal direction X with the pair of stops 16e carried by the tab 16c of each of the brackets 16.
- the support 22 (and therefore the lighting device 14) is blocked in translation in a first direction in the longitudinal direction X by the stops 16e of a first pair of brackets 16 disposed on a first longitudinal end portion 12a of the housing 12 while that it is blocked in translation in a second direction in the longitudinal direction X, opposite to the first direction, by the stops 16th of the second pair of brackets 16 arranged on the second longitudinal end portion 12a of the housing 12, arranged at the opposite in the longitudinal direction X of the first end portion 12a.
- the support 22 and the housing 12 are made from a material of the same nature, namely polycarbonate, so that the thermal expansion of the housing 12 is similar to the thermal expansion of the support 22.
- the housing 12 is transparent while the support 22 is opaque.
- the outside diameter of the support 22 is substantially equal to the inside diameter of the housing 12 (while of course allowing the support 22 to be fitted inside the housing 12), so that the support 22 cooperates with the casing 12 by complementary shape.
- the plate 24 is also blocked in translation in the longitudinal direction X using stops 16e.
- a tongue 26 is disposed between the stops 16e extending from the tabs 16b and 16c of one and the same bracket 16.
- the stops 16e carried by a tab among the tabs 16b and 16c block the tab 26, and therefore the plate 24, in translation in a first direction in the longitudinal direction X
- the stops 16th carried by the other tab among the tabs 16b and 16c block the tongue 26, and therefore the plate 24, in translation in a second direction according to the longitudinal direction X, opposite to the first direction.
- the tongue 16 is an "L" shaped plate screwed onto the plate 24.
- the plate 24 is metallic.
- the plate 24 is also reflective, so as to optimize the light flux emitted by the luminaire 10, by reflecting the light emitted by the fluorescent tubes 25.
- the plate is not clamped and is free to thermally expand.
- the thermal expansion differential between the plate 24 and the casing 12 on which the brackets 16 are fixed does not generate any mechanical stress in the assembly of these two elements.
- the thermal expansion differential between the plate 24 and the support 22 does not generate any mechanical stress in the assembly of these two elements.
- Each end portion 12a of the casing 12 is provided with a seal 28.
- the two seals 28 being identical, only one of the two seals is described, this description applying of course to the other seal 28.
- the seal 28 is annular and comprises a groove 28a which receives the longitudinal end 12aa of the casing 12.
- the seal 28 comprises an outer skirt 28b configured to be disposed outside the casing 12, and an inner skirt 28c configured to be disposed inside the casing 12. These two skirts 28b and 28c are connected by a portion of the flange 28d, these three parts thus defining the groove 28a.
- the inner skirt 28c has two cutouts 28ca, these cutouts each receiving a bracket 16.
- the outer skirt 28b has two concavities 28ba formed on its inner face, these concavities 28ba receiving the head of the screws 18. It will be noted that the length in the longitudinal direction of the outer skirt 28b is greater than the length in the longitudinal direction of the inner skirt 28c. Beyond the concavities 28ba of the outer skirt 28b in the longitudinal direction starting from the flange portion 28d, an annular groove 28bb is provided on the outer face of said outer skirt 28b. This groove 28bb is configured to receive a clamp 30, to tighten the seal 28 radially on the casing 12 in order to ensure the seal, and this without the screw heads of the screws 18 disturbing the proper functioning of the seal.
- the groove 28bb has indexes 28bc housed in cutouts 30a of the collar 30, so as to position the collar 30 in a predetermined position relative to the seal 28 and to the casing 12.
- these cutouts 30a and index 28bc substantially correspond to the position of the brackets 16 and to the cutouts 28ca.
- the enclosure of the housing 12 is closed, at each of the two open longitudinal ends 12aa, respectively by a cover 20a and a cover 20b.
- the difference between the cover 20a and the cover 20b is that the cover 20a has holes equipped with cable glands 20aa for the passage of electric power cables, and that it is provided with an internal projection 20ab extending longitudinally.
- the covers 20a and 20b are identical.
- the 20aa cable glands can be replaced by one or more connectors.
- the two covers can be fitted with cable gland (s) and / or connector (s).
- the luminaire can be fitted with two identical covers.
- the lids 20a and 20b each have a skirt 20ac and 20bc extending longitudinally and partly covering the outer face of the outer skirt 28b of the seal 28.
- the skirt 20ac, 20bc of each of the covers 20a, 20b extends to the groove 28bb (or the collar 30) without however covering this groove 28bb. This makes it possible in particular to protect the corresponding portion of the seal from any external attack.
- the covers 20a and 20b are fixed by means of screws 32 on the brackets 16. More particularly, in this example each screw 32 is screwed into the tapped hole of the tab 16b of one of the brackets 16. Thus, each cover 20a, 20b is fixed by means of two screws 32, to two brackets 16. Of course, the tightening of these screws makes it possible to ensure the seal between the gasket and the cover. Of course, the covers can be attached with a single screw, or more than two screws.
- the projection 20ab cooperates with the switch 34 of the lighting device 14.
- the switch 34 is configured to power the device. lighting 14 with electric current from the mains, while when the cover 20a is not mounted on the housing 12, the switch 34 is configured to isolate the lighting device 14 from the mains, and therefore forms a protection in case of intervention of an operator on the luminaire 10.
- the switch 34 is protected by a cover 24b having an oblong hole configured to allow the projection 20ab to pass.
- the tongue 26 allows, in addition to blocking in translation in the longitudinal direction X of the plate 24, to have the plate 24 at a predetermined position within the housing 12, whereby it is ensured that the plate 24 (or, more generally, the lighting device 14), and therefore the switch 34, has a suitable position with respect to the cover 20a so as to be able to be activated in a satisfactory manner during the assembly / disassembly of the cover 20a.

La fabrication des luminaires longitudinaux connus est souvent complexe, longue et couteuse. En effet, le nombre de pièce est en général élevé tandis que les opérations d'assemblage comprennent généralement au moins une étape de collage, la colle étant coûteuse et le temps de séchage long. Il existe donc un besoin en ce sens. Les documents
Un mode de réalisation concerne un luminaire longitudinal comprenant un carter cylindrique s'étendant selon une direction longitudinale, ledit carter étant au moins en partie transparent, et un dispositif d'éclairage disposé à l'intérieur du carter, dans lequel le dispositif d'éclairage et le carter sont assemblés uniquement à l'aide d'une pluralité d'équerres.One embodiment relates to a longitudinal luminaire comprising a cylindrical casing extending in a longitudinal direction, said casing being at least partly transparent, and a lighting device arranged inside the casing, in which the lighting device and the housing are assembled using only a plurality of brackets.
On comprend que le carter est un carter extérieur qui forme une enveloppe recevant le dispositif d'éclairage et l'isole du milieu extérieur. Le carter présente une forme cylindrique, dont la section transverse à la direction longitudinale peut être circulaire, mais pas nécessairement. Ainsi, le carter présente une forme de profilé, ouvert à ses deux extrémités longitudinales. Bien entendu, le carter est en tout ou partie transparent de manière à laisser passer la lumière émise par le dispositif d'éclairage. Selon une variante, le carter est entièrement transparent. Une seule extrémité longitudinale du carter peut être ouverte, ou bien les deux extrémités longitudinales sont ouvertes.It is understood that the casing is an outer casing which forms an envelope receiving the lighting device and isolates it from the external environment. The housing has a cylindrical shape, the section of which transverse to the longitudinal direction may be circular, but not necessarily. Thus, the casing has the shape of a profile, open at its two longitudinal ends. Of course, the casing is wholly or partly transparent so as to allow the light emitted by the lighting device to pass. According to a variant, the casing is entirely transparent. Only one longitudinal end of the housing can be open, or both longitudinal ends are open.
Une pluralité d'équerres, c'est-à-dire au moins deux équerres, permettent d'assembler le dispositif d'éclairage au carter, le dispositif d'éclairage étant logé au sein du carter. Ainsi, le dispositif d'éclairage est monté au sein du carter via les équerres. En d'autres termes, le dispositif d'éclairage est monté sur les équerres, qui elles-mêmes sont montés sur le carter. Par conséquent, le dispositif d'éclairage est monté sur le carter par l'intermédiaire des équerres uniquement. On comprend donc qu'aucun autre élément que les équerres n'intervient dans l'assemblage réalisé entre le dispositif d'éclairage et le carter.A plurality of brackets, that is to say at least two brackets, make it possible to assemble the lighting device to the housing, the lighting device being housed within the housing. Thus, the lighting device is mounted within the housing via the brackets. In other words, the lighting device is mounted on the brackets, which themselves are mounted on the housing. Consequently, the lighting device is mounted on the housing by means of the brackets only. We therefore understand that no any element other than the brackets is involved in the assembly made between the lighting device and the casing.
Un tel assemblage présente une structure simple, ayant un nombre de pièce réduit, qui est donc facile à assembler, et présente un coût réduit de fabrication et d'assemblage tout en étant fiable et robuste.Such an assembly has a simple structure, having a reduced number of parts, which is therefore easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust.
Dans certains modes de réalisation, les équerres sont fixées au carter par boulonnage ou équivalent (i.e. par des moyens de boulonnage ou équivalent).In some embodiments, the brackets are fixed to the housing by bolting or the like (i.e. by bolting means or the like).
Par « boulonnage ou équivalent » on entend tout mode de fixation qui permet d'assembler les équerres au carter en traversant la paroi du carter, par exemple à l'aide d'un boulon, d'une vis, d'un rivet, etc.By "bolting or equivalent" is meant any method of fixing which makes it possible to assemble the brackets to the casing by passing through the wall of the casing, for example using a bolt, a screw, a rivet, etc. .
Chaque équerre est donc fixée au carter via au moins un trou ménagé dans la paroi du carter. Selon une première variante, chaque équerre est boulonnée au carter via un unique trou. Selon une autre variante, chaque équerre est fixée au carter via deux trous, un trou servant au boulonnage ou équivalent de ladite équerre, l'autre trou servant à bloquer l'équerre en rotation via un taquet de blocage. Selon encore une autre variante, chaque équerre est fixée au carter via deux trous, chacun des deux trous servant au boulonnage ou équivalent de ladite équerre.Each bracket is therefore fixed to the casing via at least one hole made in the wall of the casing. According to a first variant, each bracket is bolted to the housing via a single hole. According to another variant, each bracket is fixed to the housing via two holes, one hole serving for bolting or equivalent of said bracket, the other hole serving to block the bracket in rotation via a locking cleat. According to yet another variant, each bracket is fixed to the casing via two holes, each of the two holes serving for bolting or the equivalent of said bracket.
Dans certains modes de réalisations, chaque équerre est fixée au carter via deux trous, ces trous étant distants de moins de 5.0 cm (cinq centimètres) selon la direction longitudinale. Un tel écartement entre les trous n'est pas ou très peu modifié lors de la dilatation thermique du carter lorsque le luminaire est éclairé ou lorsqu'il est placé dans un environnement particulièrement chaud (et ne génère donc aucune contrainte mécanique additionnelle), tandis que la fixation des équerres au carter via deux trous est satisfaisante.In some embodiments, each bracket is fixed to the housing via two holes, these holes being less than 5.0 cm (five centimeters) apart in the longitudinal direction. Such a spacing between the holes is not or very little modified during the thermal expansion of the casing when the luminaire is lit or when it is placed in a particularly hot environment (and therefore does not generate any additional mechanical stress), while the fixing of the brackets to the casing via two holes is satisfactory.
Grâce à la fixation des équerres au carter par boulonnage ou équivalent, la structure d'assemblage du luminaire est simple, présente un nombre réduit de pièces, est facile à assembler, et présente un coût réduit de fabrication et d'assemblage tout en étant fiable et robuste.Thanks to the fixing of the brackets to the housing by bolting or equivalent, the assembly structure of the luminaire is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable. and robust.
Dans certains modes de réalisation, le carter est en verre ou en matériau polymérique. Par exemple, le matériau polymérique est du polycarbonate (également connus sous l'acronyme « PC) » ou du polyméthacrylate de méthyle (également connus sous l'acronyme « PMMA »). De manière plus générale, le matériau polymérique est par exemple un matériau polymérique organique de synthèse ou polymère organique de synthèse.In some embodiments, the housing is made of glass or a polymeric material. For example, the polymeric material is polycarbonate (also known by the acronym "PC)" or polymethyl methacrylate (also known by the acronym "PMMA"). More generally, the polymeric material is for example a synthetic organic polymeric material or synthetic organic polymer.
Le verre et le matériau polymérique sont résistants tant du point de vue mécanique que thermique, et présentent, bien entendu sous forme transparente, de très bonnes propriétés de transmission de la lumière. Par ailleurs, de tels matériaux peuvent être percés pour l'assemblage des équerres par boulonnage ou équivalent sans être endommagés. Le matériau polymérique présente par ailleurs l'avantage d'être particulièrement léger, ce qui facilite sa manipulation et permet l'utilisation de fixations moins robustes et donc moins coûteuses.The glass and the polymeric material are resistant both from a mechanical and thermal point of view, and have, of course in transparent form, very good light transmission properties. Furthermore, such materials can be drilled for the assembly of brackets by bolting or the like without being damaged. The polymeric material also has the advantage of being particularly light, which facilitates its handling and allows the use of less robust and therefore less expensive fasteners.
Dans certains modes de réalisation, le carter présente une section transversale (à la direction longitudinale) circulaire, chaque équerre comprenant un ergot de blocage en rotation du dispositif d'éclairage autour de l'axe du carter.In certain embodiments, the casing has a circular cross-section (in the longitudinal direction), each bracket comprising a lug for locking the lighting device in rotation around the axis of the casing.
Dans ce cas, le carter ayant une section transversale circulaire, il présente une symétrie de révolution et présente un axe de révolution parallèle à la direction longitudinale, cet axe étant appelé l'axe du carter.In this case, the casing having a circular cross section, it has a symmetry of revolution and has an axis of revolution parallel to the longitudinal direction, this axis being called the axis of the casing.
Un tel carter cylindrique de section circulaire, grâce à sa symétrie de révolution, est particulièrement facile à mettre en œuvre, et n'impose aucun sens de montage. Par ailleurs, en équipant chaque équerre d'un ergot de blocage en rotation, on assure le maintien en position autour de l'axe du carter, et ce en toute circonstance, du dispositif d'éclairage au sein du carter. On comprend bien entendu que, vis-à-vis de chaque équerre, le blocage opéré par l'ergot est un blocage relatif entre l'équerre et le dispositif d'éclairage. En d'autres termes, l'ergot bloque le dispositif d'éclairage par rapport à l'équerre. On comprend également que chaque ergot forme une seule et même pièce avec une équerre. Ainsi, les ergots sont des éléments distincts des moyens de boulonnage ou équivalent pour assembler l'équerre au carter.Such a cylindrical casing of circular section, thanks to its symmetry of revolution, is particularly easy to implement, and does not impose any direction of assembly. Furthermore, by equipping each bracket with a rotational locking lug, the lighting device within the casing is maintained in position around the axis of the casing, in all circumstances. It will of course be understood that, vis-à-vis each square, the blocking effected by the lug is a relative blocking between the square and the lighting device. In other words, the lug blocks the lighting device relative to the square. It is also understood that each lug forms one and the same part with a square. Thus, the lugs are separate elements from the bolting means or the like for assembling the bracket to the housing.
Ainsi, grâce à la forme du carter et aux ergots des équerres, la structure du luminaire est simple, présente un nombre réduit de pièces, est facile à assembler, et présente un coût réduit de fabrication et d'assemblage tout en étant fiable et robuste.Thus, thanks to the shape of the housing and the lugs of the brackets, the structure of the luminaire is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust. .
Dans certains modes de réalisation, le dispositif d'éclairage comprend un support s'étendant longitudinalement et comprenant une paire de gorges (ou premières gorges) s'étendant longitudinalement, l'ergot de chaque équerre étant engagé dans une gorge (ou première gorge).In some embodiments, the lighting device includes a longitudinally extending support including a pair of grooves (or first grooves) extending longitudinally, the lug of each square being engaged in a groove (or first groove).
On comprend que le support présente la forme d'un profilé, et sert au montage du dispositif d'éclairage sur les équerres. Un tel support peut par exemple présenter d'autres fonctions que le montage du dispositif d'éclairage sur les équerres, comme par exemple former un cache pour cacher les parties telles que l'alimentation et les câbles du dispositif d'éclairage, et/ou former un réflecteur pour réfléchir la lumière vers une direction prédéterminée. Selon une variante, le support est fabriqué dans un matériau de même nature que le carter, grâce à quoi les différentiels de dilatation thermiques sont évités. Ainsi, un tel support permet d'intégrer en une seule pièce plusieurs fonctions, grâce à quoi la structure du luminaire est simple, présente un nombre réduit de pièces, qui est donc facile à assembler, et présente un coût réduit de fabrication et d'assemblage tout en étant fiable et robuste.It is understood that the support has the shape of a section, and is used for mounting the lighting device on the brackets. Such a support may for example have other functions than the mounting of the lighting device on the brackets, such as for example forming a cover to hide the parts such as the power supply and the cables of the lighting device, and / or forming a reflector to reflect light towards a predetermined direction. According to a variant, the support is made of a material of the same nature as the casing, whereby thermal expansion differentials are avoided. Thus, such a support makes it possible to integrate several functions in a single piece, thanks to which the structure of the luminaire is simple, has a reduced number of parts, which is therefore easy to assemble, and has a reduced cost of manufacture and of assembly while being reliable and robust.
Dans certains modes de réalisation, chaque équerre comprend au moins une butée pour bloquer le dispositif d'éclairage en translation selon la direction longitudinale.In certain embodiments, each bracket comprises at least one stop for locking the lighting device in translation in the longitudinal direction.
On comprend que chaque équerre comprend une ou plusieurs butées, le dispositif d'éclairage coopérant en butée selon la direction longitudinale avec une seule, plusieurs ou encore avec toute les équerres. On comprend bien entendu que, vis-à-vis de chaque équerre, le blocage opéré par la ou les butée(s) est un blocage relatif entre l'équerre et le dispositif d'éclairage. En d'autres termes, la ou les butée(s) bloque(nt) le dispositif d'éclairage par rapport à l'équerre. On comprend également que chaque butée forme une seule et même pièce avec une équerre. Ainsi, les butées sont des éléments distincts des moyens de boulonnage ou équivalent pour assembler l'équerre au carter. Les butées sont également des éléments distincts des ergots de blocage en rotation du dispositif d'éclairage autour de l'axe du carter.It is understood that each bracket comprises one or more stops, the lighting device cooperating in abutment in the longitudinal direction with one, several or even with all the brackets. It will of course be understood that, vis-à-vis each square, the blocking effected by the stop (s) is a relative blocking between the square and the lighting device. In other words, the stop (s) block (s) the lighting device relative to the square. It is also understood that each stop forms one and the same part with a square. Thus, the stops are separate elements from the bolting or equivalent means for assembling the bracket to the housing. The stops are also separate elements from the lugs for locking the lighting device in rotation around the axis of the housing.
Grâce à ces butées, le dispositif d'éclairage est maintenu en position selon la direction longitudinale au sein du carter. Ces butées étant formées sur les équerres, la structure du luminaire est simple, présente un nombre réduit de pièces, est facile à assembler, et présente un coût réduit de fabrication et d'assemblage tout en étant fiable et robuste.Thanks to these stops, the lighting device is held in position in the longitudinal direction within the casing. These stops being formed on the brackets, the structure of the luminaire is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust.
Dans certains modes de réalisation, le dispositif d'éclairage comprend une platine, la platine comprenant au moins une languette coopérant en butée avec la au moins une butée d'une équerre.In certain embodiments, the lighting device comprises a plate, the plate comprising at least one tab cooperating in abutment with the at least one abutment of a square.
On comprend que la platine est la partie du dispositif d'éclairage qui porte l'alimentation, les câbles et les ampoules ou équivalent du dispositif d'éclairage. Par « ampoule ou équivalent », on entend tout élément d'éclairage tel qu'une ampoule, un tube fluorescent, un tube néon, une ou plusieurs diodes électroluminescente (ou LED), etc.It is understood that the plate is the part of the lighting device which carries the power supply, the cables and the bulbs or equivalent of the lighting device. By "bulb or equivalent" is meant any lighting element such as a bulb, a fluorescent tube, a neon tube, one or more light-emitting diodes (or LED), etc.
La languette de la platine coopère avec une ou plusieurs butées d'une équerre. Par exemple, si l'équerre ne comprend qu'une seule butée, la languette peut présenter une découpe recevant ladite butée de manière à coopérer avec la butée dans les deux sens opposés selon la direction longitudinale. Selon un autre exemple, si l'équerre comprend deux butées, la languette est disposée entre les deux butées de manière à coopérer en butée dans un sens selon la direction longitudinale avec chacune des butées. Grâce à la languette de la platine et à la butée de l'équerre, la structure du luminaire est simple, présente un nombre réduit de pièces, est facile à assembler, et présente un coût réduit de fabrication et d'assemblage tout en étant fiable et robuste.The tongue of the plate cooperates with one or more stops of a square. For example, if the square comprises only one stop, the tongue may have a cutout receiving said stop so as to cooperate with the stop in the two opposite directions in the longitudinal direction. According to another example, if the square comprises two stops, the tongue is disposed between the two stops so as to cooperate in abutment in one direction in the longitudinal direction with each of the stops. Thanks to the tongue of the plate and the stop of the square, the structure of the luminaire is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust.
Dans certains modes de réalisation, le support comprend une paire de deuxièmes gorges, ces deuxièmes gorges étant en vis-à-vis, la platine étant montée sur le support en étant insérée dans les deuxièmes gorges. Une telle structure est simple, présente un nombre réduit de pièces, est facile à assembler, et présente un coût réduit de fabrication et d'assemblage tout en étant fiable et robuste.In certain embodiments, the support comprises a pair of second grooves, these second grooves being opposite each other, the plate being mounted on the support by being inserted in the second grooves. Such a structure is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust.
Dans certains modes de réalisation, le luminaire tubulaire comprend quatre équerres, deux équerres étant montées sur chaque portion d'extrémité du carter en étant disposées en vis-à-vis.In certain embodiments, the tubular luminaire comprises four brackets, two brackets being mounted on each end portion of the casing being disposed opposite each other.
Une telle disposition symétrique des équerres permet de monter le dispositif d'éclairage au sein du carter indépendamment du sens et de l'orientation relative entre le dispositif d'éclairage et le carter. Une telle structure est simple, présente un nombre réduit de pièces, est facile à assembler et présente un coût réduit de fabrication et d'assemblage tout en étant fiable et robuste.Such a symmetrical arrangement of the brackets makes it possible to mount the lighting device within the casing independently of the direction and of the relative orientation between the lighting device and the casing. Such a structure is simple, has a reduced number of parts, is easy to assemble and has a reduced cost of manufacture and assembly while being reliable and robust.
Dans certains modes de réalisation, le luminaire longitudinal comprend un joint d'étanchéité emmanché sur chaque portion d'extrémité du carter, chaque joint présentant une gorge recevant une extrémité du carter et au moins une découpe recevant une équerre.In some embodiments, the longitudinal luminaire includes a seal fitted onto each end portion. of the casing, each seal having a groove receiving one end of the casing and at least one cutout receiving a square.
Par « portion d'extrémité » on entend une portion du carter qui s'étend depuis une extrémité longitudinale du carter sur maximum 20% de la longueur du carter selon la direction longitudinale. On comprend que chaque portion d'extrémité du carter selon la direction longitudinale est engagée dans une gorge d'un joint. Ainsi, le joint recouvre l'intérieur, l'extérieur et la face perpendiculaire à la direction longitudinale de la portion d'extrémité du carter. Le joint présente, sur sa partie interne disposée à l'intérieur du carter autant de découpes que d'équerres disposées sur la portion d'extrémité en question, grâce à quoi les équerres n'interagissent pas avec le joint et ne perturbent le bon fonctionnement du joint. Dans le cas où les équerres sont fixées au carter par boulonnage ou équivalent, la portion du joint qui recouvre l'extérieur du carter présente des concavités recevant les têtes des boulons ou équivalent, grâce à quoi le joint recouvre lesdites têtes sans que la surépaisseur que représentent les têtes ne perturbe le bon fonctionnement du joint, assurant ainsi l'étanchéité du luminaire au niveau des trous du carter pour la fixation des équerres.By “end portion” is meant a portion of the casing which extends from a longitudinal end of the casing over a maximum of 20% of the length of the casing in the longitudinal direction. It will be understood that each end portion of the housing in the longitudinal direction is engaged in a groove of a seal. Thus, the seal covers the inside, the outside and the face perpendicular to the longitudinal direction of the end portion of the housing. The seal has, on its internal part arranged inside the casing as many cutouts as there are squares arranged on the end portion in question, thanks to which the squares do not interact with the seal and do not interfere with correct operation. of the seal. In the case where the brackets are fixed to the casing by bolting or equivalent, the portion of the seal which covers the outside of the casing has concavities receiving the heads of the bolts or the like, whereby the seal covers said heads without the extra thickness that represent the heads does not interfere with the proper functioning of the gasket, thus ensuring the tightness of the luminaire at the level of the holes in the housing for fixing the brackets.
Un tel joint unique sur chaque extrémité du carter, permet d'assurer tant une étanchéité au niveau de la face d'extrémité du carter que des faces longitudinales du carter. Par exemple, un ou plusieurs colliers de serrage peuvent coopérer avec le joint, participant ainsi à l'étanchéité assurée par le joint. Par exemple, un tel collier de serrage peut également servir d'élément de fixation pour fixer le luminaire par exemple à un support mural ou directement à un mur. Grâce à un tel joint unique sur chaque extrémité libre du carter, la structure du luminaire est simple, présente un nombre réduit de pièces, est facile à assembler, et présente un coût réduit de fabrication et d'assemblage tout en étant fiable et robuste.Such a single seal on each end of the casing makes it possible to ensure both a seal at the level of the end face of the casing and of the longitudinal faces of the casing. For example, one or more clamps can cooperate with the seal, thus participating in the sealing provided by the seal. For example, such a clamp can also serve as a fixing element for fixing the luminaire for example to a wall bracket or directly to a wall. Thanks to such a single seal on each free end of the housing, the structure of the luminaire is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust.
Selon l'invention, le luminaire comprend un couvercle monté sur une extrémité du carter, le couvercle étant fixé à au moins une équerre.According to the invention, the luminaire comprises a cover mounted on one end of the housing, the cover being fixed to at least one bracket.
On comprend que le couvercle obture une extrémité longitudinale ouverte du carter. On comprend que le carter présente au moins une extrémité longitudinale ouverte pour y monter le dispositif d'éclairage. Au moins une équerre présente une patte de fixation pour fixer le couvercle monté sur le carter. La fixation est réalisée par exemple par vissage sur la patte. Ainsi, les équerres assurent plusieurs fonctions, à savoir l'assemblage du dispositif d'éclairage avec le carter et la fixation du couvercle sur le carter. Un tel couvercle peut également coopérer avec le joint éventuel, participant ainsi à l'étanchéité assurée par ledit joint. Grâce à de telles équerres, la structure du luminaire est simple, présente un nombre réduit de pièces, est facile à assembler, et présente un coût réduit de fabrication et d'assemblage tout en étant fiable et robuste.It is understood that the cover closes an open longitudinal end of the housing. It is understood that the casing has at least one open longitudinal end for mounting the device therein. lighting. At least one bracket has a fixing lug for fixing the cover mounted on the housing. The fixing is carried out for example by screwing on the tab. Thus, the brackets perform several functions, namely the assembly of the lighting device with the housing and the fixing of the cover on the housing. Such a cover can also cooperate with the optional seal, thus participating in the sealing provided by said seal. Thanks to such brackets, the structure of the luminaire is simple, has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable and robust.
Dans certains modes de réalisation, toutes les équerres sont identiques, ce qui simplifie encore la structure et le montage de luminaire.In some embodiments, all the brackets are the same, which further simplifies the structure and mounting of the luminaire.
Selon l'invention, le dispositif d'éclairage comprend au moins un interrupteur qui coopère avec le couvercle lorsque le couvercle est monté sur le carter.According to the invention, the lighting device comprises at least one switch which cooperates with the cover when the cover is mounted on the housing.
On comprend que lorsque le couvercle est monté sur le carter, l'interrupteur est configuré pour alimenter le dispositif d'éclairage en courant électrique depuis le secteur, tandis que lorsque le couvercle n'est pas assemblé au carter, l'interrupteur est configuré pour isoler le dispositif d'éclairage du secteur. Un tel interrupteur permet à l'opérateur d'intervenir sur le luminaire, par exemple pour remplacer une ampoule ou équivalent, en toute sécurité et sans besoin de couper le courant du secteur. Dans certains modes de réalisation, le au moins un interrupteur est escamoté par un capot tout en pouvant coopérer avec le couvercle lorsque le couvercle est monté sur le carter. Ceci renforce la protection de l'opérateur en cas d'intervention et lui évite d'activer l'interrupteur par inadvertance. Dans certains modes de réalisations, l'alimentation et les câbles sont également escamotées. Ceci renforce également la protection de l'opérateur. La coopération directe entre le couvercle et l'interrupteur, participe à la simplicité de la structure du luminaire, qui présente ainsi un nombre réduit de pièces, est facile à assembler, et présente un coût réduit de fabrication et d'assemblage tout en étant fiable et robuste.It will be understood that when the cover is mounted on the housing, the switch is configured to supply the lighting device with electric current from the mains, while when the cover is not assembled to the housing, the switch is configured to isolate the lighting device from the mains. Such a switch allows the operator to intervene on the luminaire, for example to replace a bulb or equivalent, in complete safety and without having to cut off the mains current. In some embodiments, the at least one switch is retracted by a cover while being able to cooperate with the cover when the cover is mounted on the housing. This increases the protection of the operator in the event of an intervention and prevents him from activating the switch inadvertently. In certain embodiments, the power supply and the cables are also retracted. This also strengthens the protection of the operator. The direct cooperation between the cover and the switch contributes to the simplicity of the structure of the luminaire, which thus has a reduced number of parts, is easy to assemble, and has a reduced cost of manufacture and assembly while being reliable. and robust.

Le luminaire 10 est décrit plus en détail en référence aux
Le luminaire 10 comprend un carter 12 dans lequel est logé un dispositif d'éclairage 14. Le carter 12 est transparent, et présente une forme de profilé cylindrique de section circulaire d'axe parallèle à la direction longitudinale X, et ouvert à ses deux extrémités longitudinales 12aa. Plusieurs équerres 16, dans cet exemple quatre équerres 16, permettent d'assembler le dispositif d'éclairage 14 avec le carter 12, à l'intérieur du carter 12.The
Dans cet exemple, toutes les équerres 16 sont identiques. Ci-après, une seule équerre 16 est décrite en détail, mais bien entendu cette description s'applique à toutes les équerres 16. L'équerre 16 comprend une portion de fixation 16a, en forme de plaque s'étendant selon la direction longitudinale X, et présentant deux trous taraudés pour la fixation de l'équerre 16 sur le carter 12, à l'aide de vis 18. Deux pattes 16b et 16c s'étendent perpendiculairement à la portion de fixation 16a, de part et d'autre de la portion de fixation 16a selon la direction longitudinale X. Les pattes 16b et 16c ont sensiblement une forme de plaque s'étendant perpendiculairement à la direction longitudinale X. La première patte 16b présente un trou taraudé pour la fixation d'un couvercle décrit ultérieurement. La deuxième patte 16c porte un ergot 16d s'étendant parallèlement à la portion de fixation 16a, à l'opposé de la portion de fixation 16a par rapport à la patte 16c. Dans le prolongement de chaque patte 16b et 16c s'étendent deux butées 16e. Sur chaque patte 16b et 16c, les deux butées 16e sont espacées et manière à délimiter une fenêtre 16f.In this example, all the
Les équerres 16 sont fixées sur le carter 12 à l'aide de vis 18, le carter 12 présentant des trous 13 à cet effet. Dans cet exemple chaque équerre 16 est fixée à l'aide de deux vis 18 arrangées selon la direction longitudinale X l'une par rapport à l'autre. Plus particulièrement, deux équerres 16 sont fixées sur chaque portion d'extrémité 12a du carter 12, à l'intérieur du carter 12 et en vis-à-vis. En d'autres termes, les équerres 16 sont disposées deux à deux diamétralement opposées. De plus, les équerres 16 sont alignées deux à deux selon la direction longitudinale X. Par ailleurs, les équerres 16 sont disposées de manière à ce que les ergots 16d s'étendent vers l'intérieur du carter 12 selon la direction longitudinale X tandis que les pattes 16b sont disposées vers le côté extérieur du carter 12 selon la direction longitudinale X.The
Le dispositif d'éclairage 14 comprend un support 22 et une platine 24. Le support 22 présente une forme d'un profilé s'étendant selon la direction longitudinale X, et présente une section transversale sensiblement demi-circulaire, et forme ainsi une portion demi-circulaire 22a. Des gorges sont formées aux extrémités de la section demi-circulaire, formant ainsi des gorges s'étendant selon la direction longitudinale X. Ainsi, deux premières gorges 22b sont orientées vers l'extérieur de la portion demi-circulaire 22a tandis que deux deuxièmes gorges 22c sont orientées vers l'intérieur de la portion demi-circulaire 22a. Chaque extrémité de la section demi-circulaire présente une seule première gorge 22b et une seule deuxième gorge 22c. Dans cet exemple, les gorges 22b et 22c sont orientées radialement par rapport à la forme demi-circulaire 22a.The
La platine 24 présente une forme sensiblement de plaque s'étendant longitudinalement et présentant des bords longitudinaux 24a. Des tubes fluorescents 25 et leurs bornes de montages sont disposés sur un premier côté de la platine 24 tandis que l'alimentation et les câbles d'alimentation (non représentés) des tubes fluorescents 25 sont disposés sur un deuxième côté, opposé au premier côté, de la platine 24. La platine 24 est montée sur le support 22 en insérant les bords longitudinaux 24a dans les deuxièmes gorges 22c. Les deuxièmes gorges 22c forment ainsi une glissière recevant la platine 24.The
La platine 24 est montée sur le support 22 de manière à ce que les tubes fluorescents 25 soient visibles tandis que l'alimentation et les câbles non représentés soient du côté du support 22 et donc escamotés. Ainsi, le support 22 forme un cache qui permet d'escamoter l'alimentation et les câbles, assurant ainsi une fonction esthétique. Par ailleurs, la surface intérieure 22aa de la portion demi-circulaire 22a est réfléchissante. Ainsi, le support 22 forme également un réflecteur permettant d'optimiser le flux lumineux émis par le luminaire 10, en réfléchissant la lumière émise par les tubes fluorescents 25.The
Pour monter le dispositif d'éclairage 14 au sein du carter 12, on dispose le support 22 à l'intérieur du carter 12 en engageant l'ergot 16d de chaque équerre 16 dans une première gorge 22b. On note que les fenêtres 16f des équerres 16 présentent la même largeur que les deuxièmes gorges 22c. Ainsi, même lorsque le support 22 est monté au sein du carter 12, il est possible de monter ou démonter la platine 24.In order to mount the
Le dispositif d'éclairage 14, et plus particulièrement dans cet exemple le support 22, est ainsi porté et bloqué en rotation autour de l'axe du carter 12 par les ergots 16d. Par ailleurs, le dispositif d'éclairage 14, et plus particulièrement dans cet exemple le support 22, coopère en butée selon la direction longitudinale X avec la paire de butées 16e portée par la patte 16c de chacune des équerres 16. Ainsi, le support 22 (et donc le dispositif d'éclairage 14) est bloqué en translation dans un premier sens selon la direction longitudinale X par les butées 16e d'une première paire d'équerres 16 disposée sur une première portion d'extrémité longitudinale 12a du carter 12 tandis qu'il est bloqué en translation dans un deuxième sens selon la direction longitudinale X, opposé au premier sens, par les butées 16e de la deuxième paire d'équerres 16 disposée sur la deuxième portion d'extrémité longitudinale 12a du carter 12, disposée à l'opposé selon la direction longitudinale X de la première portion d'extrémité 12a. Dans cet exemple, le support 22 et le carter 12 sont fabriqués à partir d'un matériau de même nature, à savoir du polycarbonate, de sorte que la dilatation thermique du carter 12 est similaire à la dilation thermique du support 22. Il n'y a donc pas, ou très peu, de différentiel de dilatation thermique entre le support 22 et le carter 12, de sorte que le blocage en translation selon la direction longitudinale X décrit ci-avant n'induit aucune contrainte liée aux dilatations thermiques de ces éléments. Bien entendu, bien qu'étant fabriqués à partir d'un matériau de même nature, le carter 12 est transparent tandis que le support 22 est opaque. Dans cet exemple, le diamètre extérieur du support 22 est sensiblement égal au diamètre intérieur du carter 12 (tout permettant, bien entendu, d'emmancher le support 22 à l'intérieur du carter 12), de sorte que le support 22 coopère avec le carter 12 par complémentarité de forme.The
La platine 24 est également bloquée en translation selon la direction longitudinale X à l'aide de butées 16e. Une languette 26 est disposée entre les butées 16e s'étendant depuis les pattes 16b et 16c d'une seule et même équerre 16. Ainsi, les butées 16e portées par une patte parmi les pattes 16b et 16c bloquent la languette 26, et donc la platine 24, en translation dans un premier sens selon la direction longitudinale X, tandis que les butées 16e portées par l'autre patte parmi les pattes 16b et 16c bloquent la languette 26, et donc la platine 24, en translation dans un deuxième sens selon la direction longitudinale X, opposé au premier sens. Dans cet exemple, la languette 16 est une plaque en forme de « L » vissée sur la platine 24. Bien entendu toute autre forme de languette est envisageable. Dans cet exemple, la platine 24 est métallique. Par ailleurs, la platine 24 est également réfléchissante, de manière à optimiser le flux lumineux émis par le luminaire 10, en réfléchissant la lumière émise pas les tubes fluorescents 25.The
Ainsi, le blocage en translation de la platine 24 étant opéré par une seule équerre 16, la platine n'est pas bridée et est libre de se dilater thermiquement. Ainsi, grâce à ce blocage à l'aide d'une seule équerre 16, le différentiel de dilatation thermique entre la platine 24 le carter 12 sur lequel les équerres 16 sont fixées ne génère aucune contrainte mécanique dans l'assemblage de ces deux éléments. De même, grâce au montage en glissière de la platine 24 avec le support 22, le différentiel de dilatation thermique entre la platine 24 et le support 22 ne génère aucune contrainte mécanique dans l'assemblage de ces deux éléments.Thus, the blocking in translation of the
Chaque portion d'extrémité 12a du carter 12 est munie d'un joint d'étanchéité 28. Les deux joints 28 étant identiques, un seul des deux joints est décrit, cette description s'appliquant bien entendu à l'autre joint 28. Le joint 28 est annulaire et comprend une gorge 28a qui reçoit l'extrémité longitudinale 12aa du carter 12. Le joint 28 comprend une jupe extérieure 28b configurée pour être disposée à l'extérieur du carter 12, et une jupe intérieure 28c configurée pour être disposée à l'intérieur du carter 12. Ces deux jupes 28b et 28c sont reliées par une portion de flasque 28d, ces trois parties délimitant ainsi la gorge 28a. La jupe intérieure 28c présente deux découpes 28ca, ces découpes recevant chacune une équerre 16. La jupe extérieure 28b présente deux concavités 28ba ménagées sur sa face intérieure, ces concavités 28ba recevant la tête des vis 18. On notera que la longueur selon la direction longitudinale de la jupe extérieure 28b est plus grande que la longueur selon la direction longitudinale de la jupe intérieure 28c. Au-delà des concavités 28ba de la jupe extérieure 28b selon la direction longitudinale en partant de la portion de flasque 28d, une rainure annulaire 28bb est ménagée sur la face extérieure de ladite jupe extérieure 28b. Cette rainure 28bb est configurée pour recevoir un collier de serrage 30, pour serrer le joint 28 radialement sur le carter 12 afin d'assurer l'étanchéité, et ce sans que les têtes de vis des vis 18 ne perturbent le bon fonctionnement du joint. Par ailleurs, la rainure 28bb présente des index 28bc logés dans des découpes 30a du collier 30, de manière à positionner le collier 30 dans une position prédéterminée par rapport au joint 28 et au carter 12. Dans cet exemple, ces découpes 30a et index 28bc correspondent sensiblement à la position des équerres 16 et aux découpes 28ca. On notera que la fixation du luminaire 10, par exemple à un support mural non représenté, est opérée via les colliers 30. Ainsi, les colliers 30 portant le carter 12 via les joints 28, ces derniers forment également un amortisseur de vibrations, préservant ainsi le luminaire 10 des vibrations qui pourraient être transmises au luminaire 10 via le support mural. La durée de vie des composants du luminaire 10 est ainsi améliorée.Each
L'enceinte du carter 12 est fermée, au niveau de chacune des deux extrémités longitudinales ouvertes 12aa, respectivement par un couvercle 20a et un couvercle 20b. La différence entre le couvercle 20a et le couvercle 20b est que le couvercle 20a présente des trous équipés de presse-étoupes 20aa pour le passage de câbles d'alimentation électrique, et qu'il est muni d'une saillie interne 20ab s'étendant longitudinalement. Ainsi, à l'exception de ces différences, les couvercles 20a et 20b sont identiques. Bien entendu, les presse-étoupes 20aa peuvent être remplacés par une ou plusieurs connecteurs. Par ailleurs, les deux couvercles peuvent être équipés de presse-étoupe(s) et/ou de connecteur(s). Selon encore une autre variante, le luminaire peut être équipé de deux couvercles identiques.The enclosure of the
Les couvercles 20a et 20b présentent chacun une jupe 20ac et 20bc s'étendant longitudinalement et recouvrant en partie la face extérieure de la jupe extérieure 28b du joint 28. Comme cela est visible sur la
Les couvercles 20a et 20b sont fixés au moyen de vis 32 sur les équerres 16. Plus particulièrement, dans cet exemple chaque vis 32 est vissée dans le trou taraudé de la patte 16b d'une des équerres 16. Ainsi, chaque couvercle 20a, 20b est fixé à l'aide de deux vis 32, à deux équerres 16. Bien entendu, le serrage de ces vis permet d'assurer l'étanchéité entre le joint et le couvercle. Bien entendu, les couvercles peuvent être fixés avec une seule vis, ou plus de deux vis.The
Lorsque le couvercle 20a est monté sur le carter 12, la saillie 20ab coopère avec l'interrupteur 34 du dispositif d'éclairage 14. Lorsque le couvercle 20a est monté sur le carter 12, l'interrupteur 34 est configuré pour alimenter le dispositif d'éclairage 14 en courant électrique depuis le secteur, tandis que lorsque le couvercle 20a n'est pas monté sur le carter 12, l'interrupteur 34 est configuré pour isoler le dispositif d'éclairage 14 du secteur, et forme donc une protection en cas d'intervention d'un opérateur sur le luminaire 10. On note que l'interrupteur 34 est protégé par un capot 24b présentant un trou oblong configuré pour laisser passer la saillie 20ab. Ainsi, l'opérateur qui démonte le couvercle 20a ne peut pas, sauf de manière délibérée, agir sur l'interrupteur autrement qu'en remontant le couvercle 20a. On notera que la languette 26 permet, en outre du blocage en translation selon la direction longitudinale X de la platine 24, de disposer la platine 24 à une position prédéterminée au sein du carter 12, grâce à quoi on s'assure que la platine 24 (ou, plus généralement, le dispositif d'éclairage 14), et donc l'interrupteur 34, a une position adéquate par rapport au couvercle 20a de manière à pouvoir être activé de manière satisfaisante lors du montage/démontage du couvercle 20a.When the
