Description

Title of the invention: SIGNAL LIGHTING BLOCK TECHNICAL FIELD OF THE INVENTION

[0001] The technical field of the invention is that of home automation signaling lighting blocks.

[0002] The present invention relates to a signal lighting unit for ceiling or wall mounting and in particular to an emergency exit signal lighting unit. TECHNOLOGICAL BACKGROUND OF THE INVENTION

[0003] The present invention relates to an emergency or information signaling lighting unit, in particular an evacuation signaling lighting unit.

[0004] Due to the structural conditions of a building, signaling lighting units must be installed where they clearly and unambiguously indicate information such as emergency routes. This means that these lighting units must be mounted on the wall or ceiling depending on the room configuration and available space. The lighting units must have mounting devices suitable for different types of ceiling or wall mounting, comprising a mounting base and a signaling light panel unit removably connected to each other by means of connecting elements.

[0005] Lighting units often require, on the one hand, electronics to convert the alternating current supply to direct current for the light illuminating the sign, and on the other hand, connection plugs for connecting to the alternating current mains supply. Furthermore, emergency lighting units for informing emergency routes include batteries in case of a mains power failure. The electronic components and the connection plugs are often connected to each other by a cable, which can be difficult for the operator to connect, particularly when the unit is ceiling-mounted.

[0006] Two-part lighting units are known, comprising a mounting housing with fixing elements for ceiling or wall mounting, and two different panel-holding housings for attaching to the mounting housing depending on whether it is ceiling or wall mounted. However, such a lighting unit requires one of the two panel-holding housings to be discarded depending on the mounting method (ceiling or wall), which is costly and environmentally unfriendly.

[0007] A lighting unit comprising a base having a surface area substantially identical to that of the display panel is also known, allowing the panel to be mounted either against a wall parallel to the base or against a ceiling perpendicular to the base. However, the base comprises a large surface area in the case of Mounting against a ceiling may prevent installation in certain areas. Furthermore, the mounting hardware and electrical connection between the base and the panel are different and should be discarded if not used.

[0008] Furthermore, the panels of lighting units are often complex to mount. Indeed, when choosing the pictogram to display in the lighting unit, a removable panel is necessary to allow for interchangeability with the panel containing a different pictogram. Specifically, it is known to use a portion of the housing that provides the mechanical connection between the panel and the part fixed to the vertical or horizontal support (wall or ceiling). This housing includes a slot in its longitudinal surface into which the panel is inserted, held in place on the inside and protruding on the outside. However, such a mounting method is complex and can scratch and weaken the panel.

[0009] There is therefore a need for a simple, robust, and adaptable signal lighting unit that can be mounted on a ceiling or wall without any parts requiring disposal depending on the installation. Summary of the invention

[0010] The invention offers a solution to the problems mentioned above, by proposing a lighting unit adaptable to mounting on a wall or ceiling without adding any parts, through a simple and efficient assembly.

[0011] One aspect of the invention relates to a signal lighting unit comprising: • a mounting base, extending longitudinally and comprising: • a first connector housing, a second connector housing, oriented at 90° to the first connector housing to receive a connector, • a first and a second interlocking element on each longitudinal side, • a removable electrical connector, fixed to the base in the first or second housing, • a luminous traffic sign system comprising: • a framework including: • a first and a second interlocking element on each longitudinal side of the frame, in which one of the two interlocking elements of the base or frame are elastically deformable tabs inserted into the other two interlocking elements of the frame or base respectively, • a closing panel mounted against the base, together forming a casing, a lighting device housed within the frame, including a connector electrical plugged in with the removable electrical connector, • a panel mounted in the frame and including a pictogram. ?

[0012] Thanks to the invention, the lighting unit can be installed on a wall or ceiling without requiring the use of different parts and in a simple manner. Having a removable connector that can be positioned in two different slots in the base allows the user to connect the lighting device to the electrical network without needing to be connected by simply fitting the first and second interlocking elements of the frame and base together. Such a lighting unit allows the user to have only one part in hand at each stage of installation at height (on a ladder, stepladder, or scaffolding, for example). In fact, they only need to have the following in hand: • the base for attaching it to the support, • the connector for connecting it to the network (including the mains power) and its insertion into the fixed base housing, • of the light sign device to fit it with the base by means of the first and second interlocking elements of the frame and the base by blindly inserting the removable connector with that of the light device.

[0013] The blind connection of the two electrical connectors simplifies installation for the installer. Indeed, unlike prior art, the operator does not need to wire the lighting device overhead. Furthermore, the two housings are not additional parts, so there are no parts to discard depending on the installation direction; the removable connector serves as a link between the device's electrical connector and the network in both mounting orientations. In other words, the lighting device only requires one electrical connector for connection to the home automation electrical network. Moreover, this allows the illuminated sign device to require only one electrical connector.The illuminated traffic sign device has two mounting positions relative to the base: a wall mounting position and a ceiling mounting position via the first and second interlocking elements of the base.

[0014] In addition to the characteristics just mentioned in the preceding paragraph, the lighting unit according to one aspect of the invention may have one or more complementary characteristics among those described in the following paragraphs, considered individually or according to all technically possible combinations.

[0015] According to one embodiment, the base further comprises: • a first flat wall extending longitudinally and comprising: • an external positioning surface, • an internal surface opposite to the external surface, and • means of fixing to a support, • a second wall extending perpendicularly from one edge of the first wall, comprising an internal surface and, opposite it, an external surface, • in which the first dwelling extends from the internal surface of the first wall and the second dwelling extends from the internal surface of the second wall. • According to an example, the second wall is flat. • In another example, the second wall is curved, for example in the shape of of a cylinder section. • As an example, the first interlocking element of the base extends perpendicularly to the first longitudinal ends of the first and second walls, and the second interlocking element of the base extends perpendicularly to the second longitudinal ends of the first and second walls located longitudinally opposite to the first longitudinal ends. This allows the interlocking element to be used as lateral support for the housing formed between the base and the frame, and also to utilize a readily deformable area of ​​the base for the interlocking element.

[0016] According to one embodiment, the base further comprises at least one cable gland located between the first and second compartments of the base. This allows for the passage of mains or data cables for connection to the removable connector. The cable gland may be made of rubber or plastic and passes through from the inner surface to the outer surface.

[0017] According to one embodiment, • The lighting device includes an electronic circuit board mounted in the frame and electrically connected to the electrical connector, • the base further includes a partition wall located on one side between the first and second connector housing and on the other side between the electronic board and a second external wall of the base.

[0018] This allows the wiring wires to be channeled to prevent the cables from coming into contact with the electronic board.

[0019] According to an example of this embodiment and the preceding embodiment, the partition wall is located opposite the cable gland. This helps to fold the cables in the base and thus facilitates the operator's assembly of the base with the light panel device.

[0020] According to one example, the separating wall is in contact with an edge of the electronic board. This allows for simplified mounting of the lighting unit and the use of the base as a means of securing the electronic board.

[0021] According to one example, the separating wall extends perpendicularly from the second wall of the base and is arranged to hold the electronic board either by a flat surface perpendicular to the wall of the base or by its free edge parallel to the wall of the base depending on the horizontal or vertical mounting of the lighting block.

[0022] According to one embodiment, the elastically deformable tabs comprise a circular projection or a circular opening for cooperating with, respectively, a circular opening or a circular projection of the other interlocking elements. The circular projection facilitates assembly because the elastically deformable tabs can fit into the openings regardless of the angle between the base and the illuminated traffic signal panel device.

[0023] According to one embodiment, the first and second housings are each delimited by a pair of clip-on walls with two walls of the removable electrical connector. This simplifies the mounting of the removable connector in the base. For example, the two pairs of clip-on tabs are identical. Thus, the first clip-on tab of both pairs is identical but oriented differently, and the second clip-on tab of both pairs is identical but oriented differently.

[0024] According to an example of this embodiment, one of the two clip-on panels of the first and second pairs of clip-on panels is formed by the first and second interlocking elements, respectively. This reduces the amount of material and therefore the weight, cost, and CO2 footprint.

[0025] According to one embodiment, the removable electrical connector or the electrical connector of the lighting device comprises female plugs that are open laterally and open at the front, and in that, respectively, the electrical connector of the lighting device or the removable electrical connector comprises male plugs inserted through the lateral opening or the front opening of the other electrical connector. This allows the electrical connector of the illuminated sign device and the removable connector to comprise only one electrical plug per mains line, i.e., a first plug for a neutral line, a second plug for an earth line, a third plug for a phase line, and optionally a fourth plug for an information line.Furthermore, the opening plane (lateral and frontal) of these plugs allows for random angular mounting of the light block on the base (in this plane), making it easier for the installer to plug in, since the mounting is angularly free between the two extreme positions and not only strictly lateral or frontal.

[0026] According to one embodiment, the lighting device comprises a light strip electrically powered via the electrical connector, and the illuminated traffic sign device further comprises: • a first and a second glass jar, • a reflective screen, and • in which the frame includes central support tabs to create a lighting gap between the reflector and the sign, with the light strip mounted on the frame to illuminate this gap. This allows the sign to be easily positioned within the frame for visibility from either side. Furthermore, the light strip illuminating the space between the reflector and the sign provides simple and effective illumination of the entire sign. • In one example, the reflective screen includes a pictogram. The illuminated unit then has two viewing faces, each with a pictogram (as in a double-sided ceiling installation). The two pictograms, while illuminating, act as reflectors for each other, reflecting some of the light back into the illuminated area of ​​the signpost. The reflective screen can be transparent, allowing its pictogram to be illuminated from its outer surface while reflecting some of the light back towards the sign. The sign itself can also be transparent and reflective, illuminating the pictogram and reflecting some of the light back towards the reflective screen.

[0027] Another aspect of the invention relates to an assembly comprising the lighting unit according to one of the preceding embodiments and a plurality of panels, each bearing different evacuation pictograms. This allows the desired pictogram to be displayed as needed, thus requiring only one reference. According to an example of the lighting unit embodiment comprising a reflective screen, the reflective screen is one panel among the plurality of panels.

[0028] Another solution is for the user to choose the lighting unit with the panel having the desired pictogram.

[0029] Another aspect of the invention relates to a method of mounting the lighting unit against a vertical support, i.e. a wall or a horizontal support, i.e. a ceiling, the method comprising; • a first step of fixing the base against the horizontal or vertical support, • a second step of connecting the removable connector electrically to the mains, • a third step of inserting the removable connector into the first or the second housing according to its fixing against the horizontal or vertical support, • then, after mounting the panel if necessary in the frame, a fourth step of fitting the first and second fitting elements of the frame and base together by blindly inserting the removable connector with that of the light device.

[0030] The invention and its various applications will be better understood by reading the following description and examining the accompanying figures. BRIEF DESCRIPTION OF THE FIGURES

[0039] The figures are presented for illustrative purposes only and are in no way limiting of the invention.

[0040] [Fig. 1A] and [Fig. 1B] show an exploded schematic representation of a signal lighting unit according to an embodiment of the invention in two different views. The signal lighting unit comprises a mounting base 1, a removable electrical connector 2, and a signal light panel device 3.

[0041] Figures 3 and 4 show, on each side, an exploded perspective view of the lighting unit comprising the mounted signal light panel device 3, the electrical connector 2, and the base 1 configured for mounting on a horizontal support. Figures 5 and 6 show, on each side, an exploded perspective view of the lighting unit comprising the signal light panel device signaling 3 mounted, electrical connector 2 and base 1 configured to be mounted on a vertical support.

[0042] The base comprises a first longitudinal wall 10 for fixing to a support extending longitudinally between a first longitudinal end 10a and a second longitudinal end 10b, and a second longitudinal wall 11 extending perpendicularly from a longitudinal edge of the first wall 10 between a first longitudinal end 1a and a second longitudinal end 11b.

[0043] Preferably, the first wall 10 is flat. The first wall 10 comprises an internal surface lOi and an external surface 10e, opposite the internal surface lOi. Figure 2 shows a view of the base 1 from the side of the internal surface lOi. The external surface 10e is arranged to be pressed against a horizontal or vertical support. In this example, the first wall 10 includes fastening means, which are in this case two oblong through-holes lOv, 10v', perpendicular to each other, allowing the base 1 to be easily fixed, for example, with screws. Optionally, in this example, the base 1 includes a partition wall 14 and, in this case, at least one cable gland lOf (concealed by the partition wall 14 in Figure 2).The separating wall 14 extends perpendicularly from the second wall 11, parallel to the first wall 10, and is located between the first and second connector housings 12a, 12b, opposite the cable gland lOf. The cable gland lOf allows for the sealed insertion of wires from an electrical network or cable. The cable gland lOf can, for example, be made of an elastomer with elastic properties, such as SEBS (polystyrene polyethylene-butylene), and the first wall 10 is made of a rigid plastic, such as polypropylene plastic (PP) or polycarbonate (PC). For example, the cable gland lOf is overmolded into the first wall 10 or fitted into an opening in the first wall 10. In another example, the cable gland lOf forms part of the first wall 10.

[0044] In this example, the second wall is flat and therefore extends longitudinally perpendicular to the first wall 10.

[0045] The removable electrical connector 2 includes electrical plugs, in this case female, and two clips 21, in this case female, for fitting into the base 1. In addition, the electrical connector 2 includes a bogie (with or without screws, of the pinch spring type), for connecting to conductor cores of a network whose sector (phase, neutral and earth) and at least one information line.

[0046] The base 1 comprises a first connector housing 12a and a second connector housing 12b, oriented at 90° to the first connector housing 12a, each designed to receive the removable electrical connector 2, depending on whether the base is mounted on a horizontal or vertical support. The base 1 comprises a first pair of snap-on partitions 121a, visible in [Fig. 2], delimiting the first connector housing 12a and a second pair of snap-on walls 121b delimiting the second connector housing 12a. In this example, the snap-on walls 121a, 121b of each pair extend from the first and second walls 10, 11, thus solidifying the base 1. According to another example not shown, the snap-on walls 121a of the first pair extend only perpendicularly from the internal surface lOi of the first wall 10 and the snap-on walls 121b of the second pair extend only perpendicularly from the internal surface 1li of the second wall 11.

[0047] In this example, each of the snap-on partitions 121a, 121b of the two pairs includes a stop 1210 and a clip 1211, in this case male, each located on one of the two free edges of the corresponding snap-on partition 121a, 121b. The stop 1210 and the clip 1211, together with the first and second partitions 10, 11, retain the removable electrical connector 2 in the first or second corresponding slot 12a, 12b. The clips 1211 each snap into one of the two corresponding clips 21 of the removable electrical connector 2.

[0048] The illuminated traffic sign device 3 comprises: • a frame 30 comprising a first and a second interlocking element 31a, 31b to fit together with the base 1, • a light device 32 housed in the frame 30, comprising an electrical connector 321 including plugs, in this case male, for connecting with the plugs of the removable electrical connector 2, and • a panel 34 mounted in frame 30 including a pictogram.

[0049] In this case, the removable electrical connector 2 comprises female plugs that are open laterally and open at the front, and the electrical connector 321 of the light-emitting device 32 comprises male plugs inserted through the lateral opening when the removable electrical connector 2 is housed in the first slot 12a, or through the front opening when the removable electrical connector 2 is housed in the second slot 12b. The front and lateral openings form an opening plane for these plugs, allowing for random angular mounting of the light-emitting unit on the base (within this plane), thus facilitating insertion for the installer, since the mounting is angularly free between the two extreme positions and not only strictly lateral or frontal.

[0050] The base 1 comprises a first interlocking element 13a located on one longitudinal side and a second interlocking element 13b located opposite the first interlocking element, on the other side of the base 1.

[0051] In this example, the first and second interlocking elements 13a, 13b are each an elastically deformable tab. According to another example, the first and second interlocking elements 31a, 31b of the frame 3 are each an elastic tab- tickly deformable.

[0052] In this case, the first interlocking element 13a includes a tab 131a extending at 45° between the first and second walls 10, 11, at the corner formed between the first longitudinal end 10a of the first wall 10 and the first end 1a of the second wall 11. The second interlocking element 13b includes a tab 131b extending at 45° between the first and second walls 10, 11, at the corner formed between the second longitudinal end 10b of the first wall 10 and the second end 11b of the second wall 11.

[0053] The first interlocking element 13a further comprises, in this example, a circular projection 130a for interlocking with the first interlocking element 31a of the frame 30, in this case a circular opening. The second interlocking element 13b further comprises, in this example, a circular projection 130b for interlocking with the second interlocking element 31b of the frame 30, in this case a circular opening. Of course, according to other examples, the projection may be on one or both of the interlocking elements 31a, 31b and the opening on one or both of the interlocking elements 13a, 13b.

[0054] The shape of the projection 130a, 130b and the shape of the opening 310a, 310b are preferably identical but may have a shape other than circular, such as square.

[0055] The frame 30 comprises a closing wall 301 extending longitudinally, in this case between the two interlocking elements 31a, 31b, to form a housing with the base 1 by interlocking them. The free edge of the closing wall 301 is in contact either with the free edge of the first wall 10 for mounting on a horizontal support, or with the free edge of the second wall 11 for mounting on a vertical support. The base further comprises, in this example, a first side wall 15a and a second side wall 15b, each located near the first and second interlocking elements 13a, 13b, respectively. The closing wall 301, the first and second longitudinal walls 10, 11, form a housing, in this case with a U-shaped cross-section, closed laterally by the first and second side walls 15a, 15b.

[0056] Thus, when the user mounts the signal lighting unit on a horizontal or vertical support, he begins by: • pass the wires or cables of the electrical network through the cable gland lOf, • fix the base 1 to the support by pressing the outer surface 10e of the first wall 10, (this step can be carried out before or after one or both of the following steps), • Connect the network wires to the terminal block of removable electrical connector 2, • Insert the removable electrical connector 2 into the first 12a slot if the support is vertical or in the second housing 12b if the support is horizontal, • Fit the frame 30 of the light sign device 3 against the base 1 by fitting its fitting elements 31a, 31b with those of the base 1, orienting the panel 34 vertically when the support is horizontal or orienting the panel 34 horizontally when the support is vertical; during this step, the plugs (in this case male) of the electrical connector 321 of the light device 32 are inserted blindly into the plugs (in this case female) of the removable electrical connector 2 either through the side opening when it is in the first housing 12a or through the front opening when it is in the second housing 12b.

[0057] In this example of the signal lighting unit, the signal light panel device 3 is removable to allow the user to insert the panel 34 with a chosen signal pictogram.

[0058] The lighting device 32 includes, in this instance, an electronic board 320 mounted in the frame 30 and electrically connected to the electrical connector 321. The separating wall 14 is located between the electronic board and the second wall 12, from which it extends to guide and secure the cables. In this example, the edge of the electronic board 320 is secured against the separating wall 14. The frame 30 includes two internal housing walls 302 open on the side of the base 1, forming a housing for the electronic board 320. The two internal housing walls 302 further include a housing 303 for a battery 33 of the lighting device 32, which is electrically connected to the electronic board 320 to illuminate the panel 34 when the mains power is off.In this particular example, the two internal walls of housing 302 are curved, forming a housing whose laterally widened cross-section as they were joined together, forming a bottom opposite the base 1. Each of the two internal walls of housing 302 includes two openings for the passage of battery 33, because in this example the cross-section at the bottom of the battery housing is narrower than that of battery 33.

[0059] The lighting device 32 includes a light strip 322 connected to the electronic board 320 to be electrically powered by the network via the electrical connector 321 or by the battery 33.

[0060] The illuminated traffic sign device 3 further comprises a first and a second lens 35a, 35b and a reflector screen 36 for reflecting light towards the side of the sign 34. Thus, the user can choose from which side the sign 34 is visible. Each of the two lenses is clipped to the frame 30 by its peripheral edges and optionally by a clip on the closing wall 301. The sign 34 is transparent in this case, but it could be opaque. The frame 30 comprises Central mounting brackets 307 create a lighting gap between the reflector screen 36 and the panel 34. The light strip 322 is mounted on the frame 30 to illuminate this gap. Specifically, the central mounting brackets 307 extend from the bottom of the internal walls of the housing 302 to a peripheral longitudinal wall of the frame 30 located opposite the base 1. In one example, the reflector screen 36 also includes pictogram(s), i.e., it functions as a sign. The illuminated sign 3 then has two reading faces with two pictograms (as in a double-sided ceiling installation). The panel 34 also reflects light towards the reflector screen 36, and together, while illuminating, they act as reflectors for each other within the lighting gap. The reflective screen 36 can, according to another example, comprise only an internal reflective surface.

[0061] In this case, the frame 30 further includes a light strip support 305 extending longitudinally in the frame 30 between two peripheral side walls of the frame 30, and the light strip 322 is mounted on this light strip support 305. In this case, the light strip support 305 is closer to the peripheral longitudinal wall of the frame 30 than to the internal walls of the housing 302.

[0062] The invention also relates to an assembly comprising the lighting unit according to this example and a plurality of panels each comprising different evacuation pictograms.

[0063] Unless otherwise specified, the same element appearing on different figures has a unique reference.
