In the invention, a luminaire is a lighting device intended to be installed in a room, a dwelling to illuminate at least locally its interior volume. It can still be used in industry, for example, for lighting animal incubators to promote the growth of farm animals, in an oven to increase the development of algae.

The luminaire 100 presented on the Fig. 1 features an elliptical geometry. It is intended to be fixed under a ceiling by being suspended therefrom, for example by means of cables.

It consists of a receiving profile 200 forming a frame, a lighting means 150 comprising a support profile 300 in which are inserted two lighting modules equipped with electroluminescent components, two light diffusers 800, and two strips 820 forming a retaining belt of the two diffusers 800 on the receiving profile 200.

The receiving profile 200 consists of a plate of metal material folded so as to have a section C. It is closed at its two ends respectively by two flanges 202 for fixing the retaining belt of the diffusers. Cross members 250 laterally secured to the receiving profile 200 reinforce the supporting structure of the luminaire when they are fixed on the diffuser retaining belt.

A connector intended to be connected to a power supply circuit completes the structure of the luminaire.

Electroluminescent components are objects capable of emitting light when traversed by an electric current. They can be in the form of light-emitting diodes also called "LEDs". They can still be based on conductive inks, or come from products under development. On the Fig. 2 the lighting means 150 has an elongated geometry.

The support 300 is formed of a metal section, for example made of aluminum. It presents in end view, visible on the Fig. 5 an inverted T-section, comprising a relatively thick central core 310, seated one edge and perpendicular to a base wall 320. The central core 310 has respectively on its free edge and on its two sides, two returns. Two other returns are formed vis-à-vis under the base wall 320 so as to form two rails in which can be inserted respectively at least two lighting modules 400.

At least one quarter-turn captive screw 330 passes freely through the base wall 310 and its free end is provided with at least one lateral lug which is capable of being retained in the housing attached to a notch corresponding made in a threaded insert 332 fixed on the intermediate wall 204 and inside the receiving profile 200, for retaining said support after rotating a quarter turn of said screw.

A spring 334 interposed between the insert 332 and the head of the screw 330 facilitates the exit of said screw head.

Each lighting module 400 consists of a PCB printed circuit board (English language) of rectangular section adapted to be inserted into a corresponding slide. A plurality of electroluminescent components such as light emitting diodes 420 are implanted on the face intended to be turned towards the outside of the printed circuit providing illumination means the ability to illuminate in two opposite directions. The diffusers 800 are positioned so that one of their side edges can be placed vis-à-vis the corresponding light emitting diodes 420. They rest for this on the base wall 320. They are held at their periphery by a metal belt anchored to the two flanges 202 and which is visible only on the Fig. 1 . The diffusers 800 remain under the receiving profile 200.

Each diffuser 800 is designed to diffuse in a direction perpendicular to that of emission of light-emitting diodes 420, that is to say downwards for a ceiling light or horizontally for a wall luminaire.

The luminaire 100 is equipped with at least one electrical connector 500, visible on the Fig. 2 , for reasons of maintenance, the mounting and rapid replacement of the lighting modules 400. The connector 500 thus consists of two electrical contacts 600 made of a conductive material such as copper, an electrical insulator 700 interposed between the two contacts and also serving as support in the receiving profile 200.

Each contact 600 has, in side view, an L-shaped section comprising a small branch intended to be fixed on the insulator 700 and a long contact leg with a corresponding module and whose free end is bent towards the outside of the L for facilitate the sliding of the contact.

The insulator 700 has, in front view, a T-shaped geometry, the vertical branch of which is arranged between the two contacts 600 while its horizontal branch is fixed on one side to the intermediate wall 204 and inside the receiving profile. 200. On the other side of the horizontal leg are fixed the two contacts 600. Two son of a power supply M are respectively welded on the long branches of the two contacts 600. The power cable through a cable pass mounted through of the reception profile 200.

The groove 340 of the central core 310 of the support 300 is widened locally to allow the introduction and removal of the two contacts 600.

On their inner faces turned vis-à-vis, the two lighting modules 400 are provided with copper plated contact zones 440 for receiving the contacts 600. Similarly and on the other side of the two modules, two other contact zones 440 copper are made and are electrically connected by a contact 620 C section to ensure electrical continuity in series between the two modules. This contact 620 is fixed by a screw 630 in the bottom of the groove 340 and through an insulated shoulder washer 640 and a wafer 650 also made of an insulating material and on which bears said contact.

The mounting of the luminaire is as follows. The two lighting modules 400 are inserted in their respective rails of the support profile 300. The contact 620 is fixed in the groove 340. This lighting subassembly is then ready to be installed in the luminaire. For this, the support 300 is placed under the receiving profile 200 and introduced by depression between the two diffusers. If necessary, its positioning is refined by pointing the screws 330 in their respective inserts. In this depressing movement, the contacts 600 come to contact areas 440 to establish an electrical connection with the modules. The screws 330 are then screwed into the inserts 332 to clamp the support 300 under the reception profile 200 of the luminaire 100.

The electrical connection of the lighting modules is thus automatically achieved during the assembly of the support profiles with the frame. Conversely, the electrical disconnection of the lighting modules is obtained by removing the profiles from the chassis.

To connect two neighboring lighting modules arranged in end-to-end alignment, they can also be connected via a connector 500 ⁽¹⁾ , shown on the drawing. Fig. 6 . It is used to connect lighting modules of relatively short length to advantageously manufacture large luminaires, that is to say incorporating several aligned lighting modules. Many of these connectors can be used to connect to track lighting modules.

It consists of an electrical insulation 700 ⁽¹⁾ , T-section and on the central wall of which are mounted overlapping four pairs of electrical contacts 600 ⁽¹⁾ capable of electrically connecting up to four lighting modules 400 , through their coppered contact areas. Each pair of electrical contacts consists of two contacts electrically joined by a conductive plate 602 fixed by a screw 604 in the edge of the central wall of the insulator 700 ⁽¹⁾ . The horizontal portion of the T-section of the insulation 700 ⁽¹⁾ is intended to be fixed on the intermediate wall and inside the receiving profile 300.

In the variant embodiment presented on the Fig. 7 , the luminaire 100 ⁽¹⁾ has a geometry in the form of a luminous slab and which is here square. The luminous slab can still have a rectangular, triangular, circular or elliptical geometry.

The luminaire 100 ⁽¹⁾ comprises a frame 200 ⁽¹⁾ perimetric, intended to be fixed on a wall, on a ceiling, on a floor covered with a glass plate or a translucent protective material, sufficiently resistant . It supports a power supply M, as well as at least one receiving section of a lighting module equipped with electroluminescent components such as light-emitting diodes. The power supply M can also be deported.

In this square luminaire, four profiles including respectively four lighting modules, are mounted at the periphery of the frame so as to illuminate towards the interior of the luminaire. Such a lighting module 400 disposed in a support profile 300 ⁽¹⁾ integral with the frame 200 ⁽¹⁾ is visible in the sectional view of the Fig. 8 .

The chassis 200 ⁽¹⁾ is constituted on these Figs. 7 and 8 , an upper wall 210 intended to be turned towards the wall, towards the ceiling or to the ground, and which is bordered at its periphery with a perimetric edge wall 220, itself extended by a short wall of 230, parallel to the upper wall 210.

On the Fig. 8 each support profile 300 ⁽¹⁾ includes, in the luminous slab luminaire, only one lighting module 400. It is made of aluminum. It presents in end view, visible on the Fig. 8 , an inverted T-section, comprising a relatively thick central core 310, seated one edge and perpendicularly to a base wall 320. The central core 310 has on its free edge and on one side, a return. Another return is formed vis-à-vis the base wall 320 so as to form a slide in which can be inserted at least one lighting module 400.

330 ⁽¹⁾ screws, captive type, through the base wall through holes 321 and open into a groove 340 ⁽¹⁾ formed in the central core 310 to fix the support profile 300 ⁽¹⁾ in the frame 200 ⁽¹⁾ and more precisely on its upper wall 210. Said screws can be anchored in threaded inserts 240 fixed in the upper wall 210. The inserts are positioned so that the lateral edge of the central core 310 of a profile, which does not contain the lighting module, is positioned against the free edge of the short wall of corresponding return 230. The height of the central core 310 is such that the base wall 320 is brought into contact with the outer face of the return wall 230. The support profiles 300 ⁽¹⁾ can thus be fixed in the frame 200 ^(1). being wedged laterally.

A diffuser 800 is placed in the frame 200 ⁽¹⁾ to diffuse, in a direction affixed to its upper wall 210 and perpendicular to that of emission of the light-emitting diodes 420, the light emitted by said diodes of the lighting modules 400. consists of a superposition of parts. The geometry of its perimeter is such that a lateral edge can be arranged opposite the light-emitting diodes 420. Its height is calculated so that the edge of its lower face rests on the rim of the base wall 320 which is turned towards the lighting modules 400, and its upper face is applied against the upper wall 210.

The diffuser 800 is also retained in the frame 200 ⁽¹⁾ via connection flanges arranged at the corners of the frame and which also serve as electrical connectors for neighboring lighting modules.

Such a connection flange 900 disposed in each of the corners of the luminaire 100 ⁽¹⁾ is presented on the Fig. 9 . The connection flange 900 is intended to locally retain the diffuser 800 in the frame 200 ⁽¹⁾ and to electrically connect the lighting modules mounted in their corresponding profiles. Specifically, it connects two neighboring modules. This connection operation is performed automatically during the depression of the support profiles 300 ⁽¹⁾ in the frame 200 ⁽¹⁾ . Conversely, the electrical disconnection is obtained by removing the profiles from the chassis.

The connection flange 900 is composed, on the Fig. 11 , a corner 910 forming an electrical insulator, at least one electrical contact 950 may be embedded in the insulation, a clamping plate 960 and a fastening means 970 such as a screw capable clamping said wafer on the corner to retain the diffuser by pressing against the upper wall of the frame. Two contacts 950a and 950b are implemented on this Fig. 11 so that two lighting modules can be connected in parallel and, if necessary, supply them with power.

The corner 910 is made of an electrically insulating material, such as a plastic material. It is intended to retain, in the frame, the two electrical contacts 950 so that they can be electrically connected with two neighboring lighting modules. It consists of a triangular plate 912 which has on its internal face intended to be turned towards the frame, two grooves 914 for receiving the two electrical contacts 950, four stops 920 for the four free ends of the two contacts, a fixing stud 930 with the clamping plate 960, and a corner pin 940.

The plate 912 has a front view of a triangle geometry and here a right isosceles triangle in correspondence with the geometry at right angles to the corners of a square or rectangular frame.

The two grooves 914 are hollowed into the inner face of the plate 912 and parallel to its longer side.

Each electrical contact 950 consists of a lamella 952 made of copper and whose two ends 954 are folded perpendicularly, forming between them a right angle. Each end 954 is folded on itself in two facets whose intersection forms an electrical contact line 955. It will be noted, in the detail view, that the ends are split longitudinally and this by crossing the electrical contact line 955 to improve the quality of the electrical contact with the contact areas of the lighting modules.

At least one positioning pin 916 spring from the bottom of each groove 914 to be housed in a corresponding hole 953 made through said blade for positioning the contact vis-à-vis the corner 910. Said pin 916 is riveted to the result of placing the electrical contact 950 in its corresponding groove 914 to hold it in place.

A dig 918 is made in the inner face of the plate 912 from its largest side and joins the two grooves 914, so as to form a passage for an electrical connection sheath to the two contacts 950.

Each stop 920 protrudes from the inner face of the plate 912 so as to serve as a support for an end 954 of an electrical contact 950 so that it can be suitably applied to a corresponding contact area of a module. lighting. It consists of a half-cylinder attached to a support plate a little longer than said half-cylinder and against which the dorsal surface of an end 954 can bear.

With reference to the Fig. 12 and in the detail view AA, the clamping plate 960 is intended, in cooperation with the fixing stud 930, to fix a corner of the diffuser 800 in the frame 200 ⁽¹⁾ . The clamping plate 960 consists of a plate 962 of square shape under which a strip 964 protrudes laterally in the corner so that its free beveled end can fit into a recess provided internally in the lug 940 so that the clamping plate is oriented in the correct position. A groove 932 at right angles is made longitudinally in the angle of the attachment stud 930 which is opposite to the one carrying the strip 964. The corner of a diffuser 800 can take place in order to be wedged laterally. The wafer is used to apply a corner of the diffuser 800 against the upper wall of the frame 200 ⁽¹⁾ , in order to retain it prisoner. The wafer 962 is traversed by a hole 965 in which the screw 970 makes it possible to clamp the clamping wafer 960 on the fixing pad 930 by screwing said screw into a tapping 934 made from the upper face of said pad and on which bears said wafer.

On the Fig. 12 the contact zones 440 of the two lighting modules 400 are mutually connected via the connector 900.

On the Fig. 9 , the lug 940 and the strip 964 take place in a gap provided between the edge walls 220 and the short walls 230 of the frame 200 ⁽¹⁾ . This gap I, delimited between the fold edges of said walls, is clearly visible on the Fig. 10 .

On the Fig. 9 , it is found that the profiles 300 ⁽¹⁾ adjacent to the wafer 962. It is then possible to extract the profiles 300 ⁽¹⁾ including the lighting modules 400 while the diffusers 800 are held in place by the connection flanges 900 .

On the Figs. 13 and 14 , passages 212 and 213 are made through the upper wall 210 of the frame 200 ⁽¹⁾ allowing the insertion of the abutments and the fixing stud so that the triangular plate of the corresponding electrical connection flange can come into abutment on said upper wall.

In an alternative embodiment, not shown, the connection flange is retained by being inserted between the upper wall 210, the short return walls 230 and being abutted against the edge walls 220.

The free end of each support plate of the connector, a little longer than said half-cylinder which adjoins it, can bear laterally on the short return wall 230 of the frame 200 ⁽¹⁾ , while the half-cylinder can bear on the upper face of the short return wall 230.

On the Fig.7 each triangular plate 912 of the connector 900 is provided with a suspension ring 919 of the luminaire 100 ⁽¹⁾ .

Each support section of a lighting module can be extracted from the luminaire frame after having unscrewed the retaining screw or screws. The electrical disconnection is performed during the extraction of the profile.

This assembly system is replaced, in a variant embodiment presented on the Figs. 15 and 16 by a clip 980 inserted and fixed, for example using a screw V, in each end of each profile 300 ⁽¹⁾ .

The clip 980 comprises a front wall 982 elastically connected to a transverse edge with a portion inserted into the end of the profile and which naturally emerges from its opposite edge, in the form of a redan 984, the frame of said inserted portion. The front wall 982 is disposed in the extension of the central core of the profile 300 ⁽¹⁾ .

The redan 984 is disposed at the junction of the base wall 320 with the central core of the profile. On the Fig. 16 this redan can be retained at the rear of the wafer 962 by simply clipping the profile in the frame 200 ⁽¹⁾ of the luminaire in the direction indicated by the arrow A. The release of the support section 300 ⁽¹⁾ can be set implemented by means of a button 986 extending the front wall 982, said button being able to pivot the front wall 982 in the direction indicated by the arrow B so that the redan 984 can be released from the clamping plate 960. The extraction of the support section 300 ⁽¹⁾ can then be envisaged.

The luminaires presented in this description are manufactured with support profiles which are rectilinear elements. It is now possible to manufacture printed circuits of flexible structure. By using curved profiles in which lighting modules made with such printed circuits are placed, it is possible to design luminaires of original shape.

For the same purpose, the electrical connection flanges can be designed to connect lighting modules other than at right angles.

In the luminaire of the invention, the replacement of the lighting modules is made possible. The connection, the electrical disconnection is performed during the depression, extraction of the profile that supports said lighting module, in the frame of the luminaire. When a light-emitting diode is defective, when you want to change the lighting quality, it is no longer necessary to replace the luminaire. The lighting means are exchanged and replaced easily in the luminaire frame.

No special knowledge of electricity is required to carry out this operation.

In use, the luminaire is economical.

On the Fig. 17 , the luminaire 100 ⁽¹⁾ which is shown is a luminous slab which has a rectangular geometry. It comprises lighting means 150 which consist of several support profiles 300 ⁽²⁾ arranged at the periphery of the frame 200 ⁽¹⁾ to illuminate towards the interior of the chassis in order to illuminate the periphery of a diffuser 800 At least one lighting module 400 incorporating light-emitting diodes is housed in each profile 300 ⁽²⁾ .

Each support section 300 ⁽²⁾ has, on the Fig. 18 , an L-shaped section comprising a side wall 350 intended to cover a edge wall 220 of the frame 200 ⁽¹⁾ , and which is extended perpendicularly by one edge by a bearing wall 360 intended to rest on the diffuser 800 to take it sandwich between the upper wall 210 of the frame 200 ⁽¹⁾ and the bearing wall 360 of the profile 300 ⁽²⁾ _.

The side wall 350 is flanked by its free edge with a first return while a second return is formed under the seat wall 360, both preferably arranged parallel to said side wall so as to form a receiving slide. at least one lighting module 400, which can thus take place in the section 300 ⁽²⁾ . This slide is also pressed against the edge wall 220 when the lighting means is fixed to the frame 200. The light-emitting diodes 420 are arranged on the lighting module 400 so as to illuminate the diffuser 800 laterally.

On the Fig. 17 , electrical connectors 500 ⁽²⁾ for supplying the lighting modules are fixed on the frame 200 ⁽¹⁾ . They are, again, connected to the lighting modules during the installation of the profiles 300 ⁽²⁾ . Each electrical connector 500 ⁽²⁾ consists of two electrical contacts 502 of U-shaped geometry, fixed, for example by screwing, on an insulator 700 ⁽²⁾ so as to be nested one inside the other without touching. The insulator 700 ⁽²⁾ also has a U-shaped geometry. It is fixed in a U-section reinforcement profile disposed inside the frame 200 ⁽¹⁾ and exits through a passage P made locally in the upper wall 210 and in a corresponding edge wall 220 of the frame 200 ⁽¹⁾ . The free ends of the two electrical contacts 502 are bent to come into contact with the contact zones 440 made on the lighting modules 400 towards their center to establish an electrical connection with the modules after the fixing of the profiles 300. ⁽²⁾ on the chassis. These reinforcing profiles are identifiable on the Fig. 19 under the reference 302.

We insert, with reference to Figs. 17 to 19 the lighting module or modules 400 in each profile 300 ⁽²⁾ , and then, for example by means of screws V, each profile 300 ⁽²⁾ is fixed on the edge walls 220 of the frame 200 ⁽¹⁾ . The screws V also pass through the lighting modules 400 to wedge them in position in the profiles 300 ⁽²⁾ and anchor in tabs 304 provided at the end of the U-section reinforcement profiles. Six sections 300 ⁽²⁾ are fixed. at the periphery of the chassis on the Fig. 17 . The mounting of the profiles 300 ⁽²⁾ electrically connects the lighting modules 400 with the supply circuit of the luminaire.

To allow the use of lighting modules equipped with larger electroluminescent components, each contact zone 440 can be electrically connected via an offset jumper with a corresponding electrical contact 502 disposed under the support wall 360 of the support profile 300 ⁽²⁾ , thus avoiding, in particular, the insulator 700 ⁽²⁾ shading the diffusers 800.

The connection of the side lighting modules 300 ⁽²⁾ is performed in the same way using electrical connectors 500 ⁽²⁾ . Each connector 500 ⁽²⁾ is also mounted in a U-section reinforcement profile, perpendicular to the first reinforcement sections, fixed inside the frame 200 ⁽¹⁾ and exits through a passage P made locally in the upper wall 210 and in a corresponding edge wall 220 of the frame 200 ⁽¹⁾ . On the Fig. 19 the reinforcing profiles 302 are secant and form reinforcing braces of the frame structure 200 ⁽¹⁾ .

On the Fig. 17 , a support section 300 of T-section incorporating lighting modules 400 on each side of its central core 310 can take place by depression in the frame 200 ⁽¹⁾ to increase the lighting power of the luminaire. He is willing on this Fig. 17 , in a median plane, midway between the two longitudinal edge walls 220 of the frame 200 ⁽¹⁾ . It is the same way as the one described with reference to Figs. 1 to 4 . Their electrical connectors, not shown, are identical to those 500 ⁽¹⁾ presented with reference to the Fig. 6 for connecting the lighting modules 400 in the profiles 300. The electrical connection lighting modules is produced at the end of the depression of the support profile 300 in the frame 200 ⁽¹⁾ . Each support section 300 is fixed on this Fig. 17 , using screws V in frame 200 ⁽¹⁾ .

The luminaire 100 presented on the Fig. 20 , proposes a rectangular geometry similar to that described above. It thus comprises lighting means 150 comprising lighting modules 400 arranged along the longitudinal edges of the frame 200 ⁽¹⁾ and lighting modules 400 arranged in a longitudinal plane midway between the two longitudinal edges of the frame 200 ⁽¹⁾ .

Unlike the previously described, the support profiles 300 and 300 ⁽²⁾ for the lighting modules are here previously mounted on the frame 200 ⁽¹⁾ and the lighting modules are then housed or removed by insertion into their respective support profiles as suggested by the arrows F + and F-. Shutters 410 intended to be fixed to the corners of the frame, on its side edge walls, allow to retain in place the lighting modules 400 in their respective profiles.

On the Fig. 22 a support section 300 ⁽²⁾ having in section an L-shaped geometry intended to be fastened, for example by screwing, on each of the two longitudinal edge walls 220 of the frame 200 ⁽¹⁾ and a profile 300 designed to be fixed, is thus distinguished. pushed through an opening in its upper wall 210 to be housed in a reinforcing section 302 U section.

The support profile 300 ⁽²⁾ again has an L-shaped section comprising a side wall 350 intended to be applied on a longitudinal edge wall 220 of the frame 200 ⁽¹⁾ , and which is extended perpendicularly by an edge by a wall support 360 intended to rest on the diffuser 800 to sandwich it between the upper wall 210 of the frame 200 ⁽¹⁾ and the support wall 360 of the profile 300 ⁽²⁾ .

On the Fig. 20 , the other two profiles 300 ⁽²⁾ intended to be fixed on the side edge walls are devoid of return because they are not intended to contain lighting modules. They are also crossed in the middle of a passage to insert the lighting modules in the central support section 300.

The central support section 300 is identical to the other profiles 300 described above. On the Fig. 22 it is fixed by means of screws V passing through its central core 310, in a U-section reinforcement section 302 of the frame 200 ⁽¹⁾ .

On the Fig. 21 , the lighting modules 400 are powered via connectors 500 ⁽³⁾ and 500 ⁽⁴⁾ when they have been fully inserted into their corresponding support profiles. Each connector is fixed in the chassis via an electrical insulator.

For this purpose, contact zones 440 are made on the lighting modules 400 at their two ends so that two lighting modules are electrically connected by the connectors 500 ⁽³⁾ and 500 ⁽⁴⁾ when they are positioned end to end.

The connector 500 ⁽³⁾ is designed to connect two 400 central lighting modules held in a T-section while the connectors 500 ⁽⁴⁾ are designed to connect the lighting modules 400 arranged on the longitudinal edge walls of the frame of the luminaire, being held in L-shaped sections.

The connector 500 ⁽³⁾ is constituted by a plurality of jumper-shaped electrical contacts having, in end view, a U-shaped geometry, comprising an intermediate fixing part in the chassis, extended from one end of two contacts 504. Each electrical contact has two wings delimited by a fold forming a clean line of electrical contact on a corresponding contact zone 440. Three jumpers constitute the connector 500 ⁽³⁾ on this Fig. 21 . One of the jumpers is mounted astride the four end-to-end ends of two parallel pairs of lighting modules 400 so as to contact polarity contact zones to electrically connect the two modules while the other two jumpers overlap. respectively contact areas of another polarity of the four lighting modules.

The connector 500 ⁽⁴⁾ consists of a plurality of jumper-shaped electrical contacts, having an L-shaped geometry in the end view, including an intermediate fixing portion in the chassis, extended by an electrical contact 504. Each electrical contact has two wings delimited by a fold forming a clean line of electrical contact on a corresponding contact zone 440. Three jumpers constitute the connector 500 ⁽⁴⁾ on this Fig. 21 . One of the jumpers is mounted in contact with the two end-to-end ends of two lighting modules so as to contact polarity contact zones to electrically connect the two modules while the other two jumpers are brought into contact. respectively on contact areas of another polarity of the two lighting modules.

On the Figs. 20 and 21 , the lighting modules 400 are threaded into their corresponding supports 300 ⁽²⁾ and 300 until their contact zones 440 are brought into contact with the electrical contacts 504 of the connectors 500 ⁽³⁾ and 500 ⁽⁴⁾ . The two types of connectors 500 ⁽³⁾ and 500 ⁽⁴⁾ are also visible on the Fig. 22 .

In these versions of the luminaire of the invention, the replacement of the lighting modules is made possible. The connection, the electrical disconnection is performed during the lateral installation of the profile that supports said lighting module, in the frame of the luminaire. These operations can still be performed by inserting, removing the lighting modules from their profiles permanently attached to the luminaire frame.

On the Fig. 23 , the lighting module 400 which is presented is positioned parallel to the upper wall 210 of the frame 200 ⁽¹⁾ of the luminaire 100, being disposed in a profile 300, so that it illuminates perpendicular to the plane of said wall higher. The profile 300 is positioned towards the middle of the frame 200 ⁽¹⁾ . A transparent optical prism PO forming an optical refractive means is placed under the lighting module 400 so that it can refract the light it emits towards two diffusers 800 arranged on either side of the prism PO , as suggested by the two arrows F1 and F2. A luminous slab is thus obtained with a proportion of illuminating surface which is larger. The light-emitting components of the lighting modules can also be placed elsewhere than vis-à-vis the diffuser wafer.

On the Fig. 24 , the two sections are positioned laterally to the frame 200 ⁽¹⁾ and incorporate two lighting modules 400 which are also positioned parallel to the upper wall 210 of said frame. Two prisms PO are respectively placed under the two lighting modules 400 so as to refract the light they emit towards a diffuser 800 disposed between the two prisms PO, as suggested by the two arrows F3 and F4.

On the Figs. 25 and 26 , the transparent prism is replaced by an optical reflection means MR consisting of a reflective prism, that is to say whose faces are covered with an optically reflective material or is still constituted by one or more mirrors .

On the Fig. 27 , the luminaire 100 ⁽¹⁾ presented comprises a frame 200 ⁽¹⁾ whose upper wall 210 is perforated. Two diffusers 800 are superimposed in the height of the frame and are separated by an optical reflector RO. At least one module 400, disposed in a profile 300, laterally illuminates each diffuser, allowing the luminaire in operation to illuminate in two opposite directions through its two main faces, as shown by the two arrows F5 and F6. Such a luminaire can be used in a vertical wall wall to illuminate both sides of the wall. It is still possible to design a suspended luminaire diffusing downward a direct light and upwards an indirectly reflected light, for example by a ceiling. It may be interesting then to adjust the power of direct or indirect lighting to provide the user with comfort adapted to his needs.

On the Fig. 28 , the two luminaires 100 ⁽¹⁾ presented are suspended from a ceiling in replacement of a false ceiling slab which normally rests on a supporting framework. They are arranged with two of their singing walls 220 which are adjacent and which can be retained in clamps E integral with the suspension rails R of the false ceiling. Each clamp E is formed of two elastic branches terminated by two return walls bent inwards and which join to clamp the two edge walls 220. Bosses 222 are formed for this purpose on the inner side of the edge walls 220 so that each luminaire can be fixed by simple clipping in the clamps E. The bosses 222 are offset in height and thus allow to precisely align the height of the fixture in the clamps. The installation of the luminaire is particularly fast. Its disassembly can be performed using a spacer tool of the two return walls.

On the Fig. 29 , the luminaire 100 ⁽¹⁾ can be suspended with the ability to tilt around supports held in the rails. For this purpose, two parallel edge walls 220 of the frame 200 ⁽¹⁾ are each provided with two retaining hooks 225 on said support. The two hooks are foldable to be able to overlap said supports.

On the Fig. 30 , this support S has in section, a U-shaped geometry whose ends of the two branches are provided with folds to be fixed on a rail while its lower part is formed of two intermediate branches, one of which forms a tilting retaining means for a corresponding hook 225.

The mounting of a luminaire of the invention can thus easily be realized in a false ceiling.
