Description

Title of the invention: SIGNALING LIGHTING UNIT 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 signaling lighting unit for ceiling or wall mounting and in particular to an emergency exit signaling lighting unit. TECHNOLOGICAL BACKGROUND OF THE INVENTION

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

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

[0005] Lighting units often require, on the one hand, electronics to transform the AC power supply current into DC for the light device illuminating the panel, and on the other hand, connection plugs for connecting to AC mains. In addition, emergency type lighting units for informing emergency routes include batteries in the event of a power outage. The electronic part and the connection plugs are often connected to each other by a cable, which can be difficult for the operator to connect together, especially when mounted on the ceiling.

[0006] Two-part lighting blocks are known, comprising a fixing housing part having fixing elements for ceiling or wall mounting, and two different panel holding housing parts for fixing to the fixing housing part depending on whether it is mounted on the ceiling or wall. However, such a lighting block requires throwing away one of the two panel holding housing parts depending on whether it is mounted on the ceiling or wall, which is expensive and not very environmentally friendly.

[0007] Also known is a lighting unit comprising a base having a surface area substantially identical to that of the panel to be displayed, making it possible to mount the panel either against a wall while being parallel to the base, or against a ceiling while being mounted perpendicular to the base. However, the base comprises a large surface area in the event of mounting against a ceiling may prevent mounting in certain areas. In addition, the fixing means and the electrical connection between the base and the panel are different and should be discarded if not used.

[0008] Furthermore, the panels of the lighting blocks are often complex to mount, in fact, in the case of choosing the pictogram to be displayed in the lighting block, it is necessary to have a removable panel to interchange the panel comprising another pictogram. In particular, it is known to use a part of the housing making the mechanical connection between the panel and the part fixed to the vertical or horizontal support (wall or ceiling), comprising a slot in a longitudinal surface, in which the panel is inserted to be retained inside and protrude outside. However, such mounting is complex, this can scratch the panel and weaken it.

[0009] There is therefore a need for a signaling lighting unit that is simple to mount, solid, and adaptable to a ceiling or a wall without any parts to be discarded depending on the mounting. 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 a room, by simple and effective mounting.

[0011] One aspect of the invention relates to a signaling lighting unit comprising: • a fixing base, extending longitudinally and comprising: • a first connector housing, a second connector housing, oriented at 90° relative 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 housing or in the second housing, • a luminous signal panel device comprising: • a framework comprising: • a first and a second interlocking elements on each longitudinal side of the frame, in which one of the two interlocking elements of the base or of the frame are elastically deformable tabs inserted into the other two interlocking elements respectively of the frame or of the base, • a closing wall mounted against the base together forming a box, a light device housed in 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 on a ceiling without requiring the use of different parts and in a simple manner. Having a removable connector that can be positioned in two different housings in the base allows the user to connect the lighting device blindly to the electrical network via this removable connector by fitting the first and second fitting elements of the frame and the base together. Such a lighting unit allows the user to have a single part in hand at each stage of assembly at height (on his ladder, stepladder, or scaffolding for example). Indeed, he only needs to have on hand: • the base for its attachment to the support, • the connector to connect it to the network (including the mains) as well as its insertion into the housing of the fixed base, • of the luminous signal panel device to fit it with the base by means of the first and second fitting elements of the frame and the base by blindly plugging the removable connector with that of the luminous device.

[0013] The blind connection of the two electrical connectors thus simplifies assembly for the installer. Indeed, unlike the prior art, the operator does not need to wire the light device at height. In addition, the two housings are not additional parts, so there are no parts to discard in the event of one assembly or the other, the removable connector serves as a link between the electrical connector of the device and the network in both assembly directions. In other words, the light device only includes a single electrical connector to connect to the home automation electrical network. In addition, this allows the light sign device to include only a single electrical connector.The illuminated signage device has two mounting positions relative to the base, a wall mounting position and a ceiling mounting position via first and second interlocking members interlocked with the first and second interlocking members of the base.

[0014] In addition to the characteristics which have just been 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 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 an external surface, • wherein the first housing extends from the inner surface of the first wall and the second housing extends from the inner surface of the second wall. • In one example, the second wall is flat. • In another example, the second wall is curved, for example in the shape of a cylinder section. • According to one example, the first nesting element of the base extends perpendicular to first longitudinal ends of the first and second walls and the second nesting element of the base extends perpendicular to second longitudinal ends of the first and second walls located longitudinally opposite the first longitudinal ends. This makes it possible to use the nesting element as lateral support for the housing formed between the base and the frame but also to use an easily deformable area of ​​the base for the nesting element.

[0016] According to one embodiment, the base further comprises at least one wire grommet located between the first and second housing of the base. This allows for a passage of wires or mains or information cables, for connection to the removable connector. The wire grommet can be made of rubber or plastic, it passes through from the internal surface to the external surface.

[0017] According to one embodiment, • the lighting device includes an electronic card mounted in the frame and electrically connected to the electrical connector, • the base further comprises a separating wall located on the one hand between the first and second connector housing and on the other hand located between the electronic card 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 previous embodiment, the separating wall is located opposite the cable grommet. This helps to fold the cables in the base and thus makes it easier for the operator to mount the base with the light panel device.

[0020] According to one example, the separating wall is in contact against an edge of the electronic card. This allows for simplified mounting of the lighting unit and for the base to be used as a means of wedging the electronic card.

[0021] According to one example, the separating wall extends perpendicularly from the second wall of the base and is arranged to wedge the electronic card 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 whether the lighting unit is mounted horizontally or vertically.

[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 makes it easier to mount because the elastically deformable tabs can fit into the holes regardless of the angle between the base and the signaling light 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 makes it possible to simplify the mounting of the removable connector in the base. According to one example, the two pairs of clip-on tabs are identical. Thus the first clip-on tab of the two pairs are identical but oriented differently and the second clip-on tab of the two pairs are identical but oriented differently.

[0024] According to an example of this embodiment, one of the two clip-on walls of the first and second pairs of clip-on walls is formed by the first and second interlocking elements respectively. This makes it possible to reduce the quantity of material and therefore reduce the weight, the cost, and the CO2 footprint.

[0025] According to one embodiment, the removable electrical connector or the electrical connector of the light device comprises laterally open and frontally open female plugs, and in that, respectively, the electrical connector of the light 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 light signaling panel 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 possibly a fourth plug for an information line.In addition, the opening plane (lateral and frontal) of these plugs allows 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 light device comprises a light strip electrically powered via the electrical connector, and the light signaling panel device further comprises: • a first and a second verrine, • a reflective screen, and • wherein the frame comprising central wedging tabs making it possible to form a lighting space between the reflector screen and the panel, the light strip being mounted on the frame to illuminate the lighting space, this makes it possible to easily place the signage panel in the frame to be visible from one side or the other side. In addition, the light strip illuminating the volume between the reflector and the panel makes it possible to have light illuminating the entire panel in a simple and effective manner. • According to one example, the reflective screen includes a pictogram. The light block then has two reading faces with two pictograms (case of a double-sided ceiling installation). The two pictograms, while illuminating, then act as reflectors for each other by reflecting part of the light into the lighting space of the illuminated signage device. The reflective screen can be transparent, allowing its pictogram to be illuminated from its external face and reflecting part of the light towards the sign. The sign can therefore also be transparent and reflective to illuminate the pictogram and reflect part of the light 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 comprising different evacuation pictograms. This makes it possible to put the desired pictogram according to the need and thus have only one reference. According to an example of the embodiment of the lighting unit 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 block 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 electrically removable connector to the mains, • a third step of inserting the removable connector into the first or second housing according to its fixing against the horizontal or vertical support, • then, after having mounted the panel if necessary in the frame, a fourth step of fitting the first and second fitting elements of the frame and the base together by blindly plugging the removable connector with that of the lighting 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 information purposes only and in no way limit the invention.

[0040] [Fig.lA] and [Fig.lB] show an exploded schematic representation of a signaling lighting unit according to an example of the invention in two different views. The signaling lighting unit comprises a fixing base 1, a removable electrical connector 2 and a signaling light panel device 3.

[0041] Figures 3 and 4 show, from each side, a perspective view of the exploded lighting unit comprising the mounted signaling light panel device 3, the electrical connector 2 and the base 1 configured to be mounted on a horizontal support. Figures 5 and 6 show from each side a perspective view of the exploded lighting unit comprising the 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 attachment 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 11a and a second longitudinal end 11b.

[0043] Preferably, the first wall 10 is flat. The first wall 10 comprises an internal surface 10i and an external surface 10e, opposite the internal surface 10i. [Fig. 2] represents a view of the base 1 from the side of the internal surface 10i. The external surface 10e is arranged to be pressed against a horizontal or vertical support. The first wall 10 comprises in this example fixing means which are in this case two oblong through fixing orifices 10v, 10v' perpendicular to each other allowing the base 1 to be fixed easily, for example using screws. The base 1 optionally comprises in this example, a separating wall 14 and in this case at least one grommet 10f (hidden by the separating wall 14 in [Fig. 2]).The separating wall 14 extends perpendicularly from the second wall 11 in parallel to the first wall 10 and is located between the first and second connector housings 12a, 12b opposite the grommet 10f. The grommet 10f makes it possible to insert wires of an electrical network or a cable in a sealed manner. The grommet 10f may for example be an elastomer having elastic characteristics, for example SEBS (Polystyrene Polyethylene-butylene), and the first wall 10 is made of hard plastic, for example Polypropylene Plastic PP or polycarbonate PC. For example, the grommet 10f is overmolded in the first wall 10 or fitted into an opening in the first wall 10. According to another example, the grommet 10f is 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 comprises electrical plugs, in this case female, and two clips 21, in this case female, to fit into the base 1. In addition, the electrical connector 2 comprises a terminal block (with or without screws, of the pinch spring type), to connect to conductor cores of a network including the 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° relative to the first connector housing 12a to each receive the removable electrical connector 2 according to a mounting of the base on a horizontal or vertical support. The base 1 comprises a first pair of clip-on walls 121a visible in [Fig.2] delimiting the first connector housing 12a and a second pair of clip-on walls 121b delimiting the second connector housing 12a. In this example, the clip-on walls 121a, 121b of each pair extend from the first and second walls 10, 11, making it possible to solidify the base 1. According to another example not shown, the clip-on walls 121a of the first pair extend only perpendicularly from the internal surface 10i of the first wall 10 and the clip-on walls 121b of the second pair extend only perpendicularly from the internal surface 11i of the second wall 11.

[0047] In this example, each of the clip-on walls 121a, 121b of the two pairs comprises a stop 1210 and a clip 1211, in this case a male clip, each located on one of the two free edges of the corresponding clip-on wall 121a, 121b. The stop 1210 and the clip 1211, with the first and second walls 10, 11, make it possible to retain the removable electrical connector 2 in the corresponding first or second housing 12a, 12b. The clips 1211 each clip into one of the two corresponding clips 21 of the removable electrical connector 2.

[0048] The luminous signal panel device 3 comprises: • a frame 30 comprising a first and a second interlocking element 31a, 31b to interlock with the base 1, • a light device 32 housed in the frame 30, comprising an electrical connector 321 comprising plugs, in this case male, for plugging into the plugs of the removable electrical connector 2, and • a panel 34 mounted in the frame 30 comprising a pictogram.

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

[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- tically deformable.

[0052] In this case, the first interlocking element 13a comprises 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 11a of the second wall 11. The second interlocking element 13b comprises 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 nesting element 13a further comprises, in this example, a circular projection 130a for fitting into the first nesting element 31a of the frame 30, in this case a circular opening. The second nesting element 13b further comprises, in this example, a circular projection 130b for fitting into the second nesting 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 nesting elements 31a, 31b and the opening on one or both nesting 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 together with the free edge of the closing wall 301 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 of U-shaped section laterally closed by the first and second side walls 15a, 15b.

[0056] Thus, when the user mounts the signaling lighting unit on a horizontal or vertical support, he begins by: • pass the wires or the cable(s) of the electrical network through the cable gland 10f, • fix the base 1 to the support by placing the external surface 10th 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 the removable electrical connector 2, • insert the removable electrical connector 2 into the first housing 12a if the support is vertical or in the second housing 12b if the support is horizontal, • fit the frame 30 of the luminous signaling panel device 3 against the base 1 by fitting its fitting elements 31a, 31b with those of the base 1, by orienting the panel 34 vertically when the support is horizontal or by 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 luminous device 32 are inserted blindly into the plugs (in this case female) of the removable electrical connector 2 either through the lateral 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 signaling lighting unit, the signaling light panel device 3 is removable to allow the user to insert the panel 34 with a chosen signaling pictogram.

[0058] The lighting device 32 comprises in this case an electronic card 320 mounted in the frame 30 and electrically connected to the electrical connector 321. The separating wall 14 is located between the electronic card and the second wall 12 from which it extends to guide and wedge the cables. In this example, the edge of the electronic card 320 is wedged against the separating wall 14. The frame 30 comprises two internal housing walls 302 open on the side of the base 1 forming a housing housing the electronic card 320. The two internal housing walls 302 further comprise a housing 303 housing a battery 33 of the lighting device 32 electrically connected to the electronic card 320 to enable the panel 34 to be illuminated when the network is cut off.In this example, the two internal housing walls 302 are curved, forming a housing whose section seen laterally decreases by being connected to each other, forming a bottom opposite the base 1. The two internal housing walls 302 each comprise two openings for the passage of the battery 33 because in this example the section at the bottom of the battery housing is less wide than that of the battery 33.

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

[0060] The luminous signaling panel device 3 further comprises a first and a second glass pane 35a, 35b and a reflective screen 36 for reflecting the light from the side of the panel 34. Thus, the user can choose from which side the panel 34 is visible. Each of the two glass panes is clipped to the frame 30 by its peripheral edges and optionally a clip on the closing wall 301. The panel 34 is in this case transparent but it could be opaque. The frame 30 comprises central wedging tabs 307 making it possible to form a lighting space between the reflective screen 36 and the panel 34, the light strip 322 being mounted on the frame 30 to illuminate the lighting space. In this case, the central wedging tabs 307 extend from the bottom of the internal housing walls 302 towards a peripheral longitudinal wall of the frame 30 located opposite the base 1. According to one example, the reflective screen 36 also comprises one or more pictograms, i.e. it can be a panel. The illuminated signaling panel device 3 then comprises two reading faces with two pictograms (case of a double-sided ceiling installation). The panel 34 also reflects the light towards the reflective screen 36 and together, therefore, while illuminating, they act as a reflector for each other in the lighting space. The reflective screen 36 may, according to another example, comprise only an internal reflective surface.

[0061] In this case, the frame 30 further comprises 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 housing walls 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 in different figures has a single reference.
