Description

The present invention relates to illuminating mirrors and more particularly to an illuminating mirror with light emitting diodes. Light-emitting diodes (LEDs) were originally used to provide warning lamps or indicator lights for electrical and electronic devices, and have already been used for a few years to illuminate signaling devices such as traffic lights. signaling, motor vehicle lights (turn signals, position lights), or portable lights or markers. The interest of the diodes is their long life, their illuminating efficiency, their robustness, making the equipment employing them more durable, and requiring a reduced maintenance. Recently their use has developed in the field of mirrors to provide illuminating mirrors. From the patent application WO2012028819, in the first embodiment shown in FIG. 1, is known an LED illuminating mirror which comprises: a glazing unit with a first main face forming the rear face, and a second principal face forming the front face; a mirror central zone, diffusing patterns on the rear face of the glass obtained here by sanding or acidizing the glass, peripheral to the mirror, along the first longitudinal edge of the glazing with a width of less than 200 mm, a group of diodes inorganic electroluminescent (or LED) arranged on the side of the rear face, along the most peripheral longitudinal edge of the diffusing strip. Each of the diodes has a given emission spectrum in the visible, for example a white light, and with a main emission radius F, said first main ray, substantially parallel to the rear face. The emission cone may be, for example, lambertian. The beam of each diode is divergent and defined by a half-angle at mid-height of 60 °. The mirror further comprises on the side of the rear face, a profile forming a reflector of the light coming from the diodes, positioned along the most central edge of the diffusing band.

The reflector profile is metallic, for example made of anodized aluminum, with a thickness of less than or equal to 3 mm, and comprises: a so-called main portion which is elongated and oblique with respect to the rear face, extending until it comes into contact with the rear face, - an elongated part, extending the main part, facing the rear face. The reflector section also includes an elongated lateral portion, extending the flat portion and substantially normal to the rear face, and carrying diodes on their PCB or PCB. To hide the end of the main part, the central mirror area overflows below the main part. The mirror is fixed to a wall (wall, ceiling, partition ...) by the lateral part forming an entourage of the mirror with a return on the front face. As an example of the dimensions of the various elements: - the surface of the glazing is 600x600mm and it is an extra-clear glass of 2.9mm thickness, - the distance between the wall and the glazing is 28mm, - the width of each first illuminating strip is 40mm and the length of each first illuminating strip is 550mm, - the width of the central decorative zone is approximately 400mm, - each card holder diodes, is 10mm wide, 550mm long, d thickness of the order of 1.9 mm and, - the diodes, without optics, are of height of the order of 2 mm, width less than 6 mm, with a regular distance between diodes of 18 mm, - the height, distance between the diodes and the first scattering patterns are of the order of 15mm, the diodes have an individual power of 0.3VV (approximately), an efficiency of at least 40 Im / VV (lumens / Watt). We seek to improve the robustness of this mirror without penalizing the efficiency or complicating its design.

For this purpose, the present invention firstly proposes an illuminating mirror which comprises: a glazing, plane or curved, in mineral glass, called facade glazing, with a first main face forming the front face, and a second main face forming the rear face and a slice, glazing preferably of thickness less than 6 mm, better 5 mm, TL light transmission greater than 85%, and better or equal to 90%, - on the back side, a metal layer based on silver (preferably silver or essentially silver, and typically coated with a protective layer), said mirror layer, giving the mirror functionality on the front side, with a light reflection RL greater than 85% better than or equal to at 90% measured on the front side of the mirror, in particular a metal layer present in a central zone of the facade glazing and preferably also at the periphery, - a diffusing pattern, on the rear face and adjacent to the mirror layer (possibly surrounded by the mirror layer except in the edge or edges of the facade glazing such as shaped edges), lateral dimension pattern of at least 10 mm, even at least 20 mm and preferably less than or equal to at 230mm, and even at less than or equal to 150mm, a pattern diffusing into a continuous diffusing element or several spaced diffusing elements: an elongated lateral dimension pattern which is the width VV1 and of length L1 (greater than VV1), preferably greater than 100mm, at least 150 mm, even at least 300 mm, in particular a rectangular pattern, in a triangular or non-geometric L-shape, preferably inscribed in a rectangular zone or in an L-shape, or disk or square-dimensional pattern of lateral dimension which is the radius r1 or the side, - or frame pattern, in one or more spaced apart bands, lateral size band (s) which is the VV1 bandwidth, a frame pattern extending over a length 1 (greater than VV1) of pref greater than 100 mm, better still at least 150 mm, even at least 300 mm, for example a frame whose outer contour is spaced from the edge of the facade glazing by at most 50 mm, the facade glazing with the diffusing pattern presenting a blur of at least 80%, better still at least 90% and even at least 95%, front side, a light transmission TL greater than 40% better or equal to 50% and even at least 65%, front side side - the side of the rear face, a first group of light emitting diodes, in a row, on a first printed circuit board PCB, preferably emitting from the top and even (substantially) perpendicular to the glazing of frontage, carried by a profile said support part, - a so-called main reflector, preferably metal or plastic or glass coated with a reflective layer (metallized, lacquered, enamelled ...), main reflector facing the first group of diodes and spaced from the first group of diodes by a so-called internal space, main reflector preferably plane or concave towards the internal space, -the light rays coming from the diodes propagating in the internal space-, main reflector comprising a reflecting wall and / or a so-called reflecting layer main internal space side -on a given wall- or main reflecting layer opposite side and on a transparent wall (preferably plastic), - a so-called bottom reflector, rear side, which is a reflecting wall - in particular parallel to the facade glazing or concave towards the inner space and / or with a reflective layer, bottom reflector adapted to receive from the first group of diodes light rays deviating from the rear face and to return them to the diffusing pattern or to the main reflector, background reflector spaced apart from the diffusing pattern by a distance H of not more than 50mm better than 40mm and in particular not less than 10mm at least 15 mm, - a support for fixing the mirror, said mirror support, preferably metal (and rear side), fixed to the rear face and / or to the bottom reflector, in particular which comprises an aperture of attachment or means of attachment to a wall including wall or furniture. The first PCB is shifted laterally from the diffusing pattern (thus without vis-à-vis with the scattering pattern) -preferably under the mirror layer-, especially in the central area or a more peripheral area. Each diode preferably has a main light ray F forming an angle of at most 10 ° better than at most 5 ° with the facade glazing (average plane of the glazing if it is curved) and a diverging beam and defined by a half-angle at mid-height of at least 40 ° better by at least 50 ° (angle defined from radius F of angle at 0 °), the adjacent diode bundles of the first group overlapping on the diffusing pattern . The first PCB is arranged (substantially all) along a first longitudinal edge of the elongate pattern or surrounds (continuously or in pieces) the disk or square pattern or surrounds (in continuous or in pieces) an internal outline or external, the frame pattern said injection contour, (without necessarily being parallel or equidistant from the scattering pattern). The illuminating mirror according to the invention comprises (rear side) a reflective surround surrounding the diffusing pattern (without necessarily being parallel or equidistant from the scattering pattern). Reflector naturally means an element reflecting visible light. In a first configuration (a), the reflective surround comprises the main reflector and the support piece for the elongate or disc or square pattern, or the surround comprises the main reflector or the support piece for the frame pattern thus surrounding the injection contour or the other contour. The reflective surround forms with the facade glazing and the bottom reflector a housing (especially sealed with liquid water) enclosing the first PCB, said dedicated housing, the surround being attached to the rear face, under the mirror layer directly and / or indirectly via one or more attachment profiles (angle etc.), in particular L, preferably made of metal, by a double-sided, liquid-tight adhesive having a thickness greater than 0.6 mm and even greater than or equal to 1 mm fixation on the periphery or at least along the two opposite walls of the entourage, (said attachment walls).

The reflective surround is in at least two parts spaced less than 5 mm especially if the assembly PCB and diodes is tight liquid water, better than 2 mm, or connected with a seal, abutment, d sealing with liquid water which is a putty, or the reflective surround forms a monolithic frame. In a second configuration, a housing (in particular waterproof liquid water), said common housing, contains the first PCB diodes and power supply means of the diodes, or means of driving the diodes ("dimmer") . The common housing comprises a frame in at least two parts spaced less than 5 mm or connected with a seal, abutment, sealing with liquid water which is a sealant, or the joint housing comprises a monolithic frame.

The most peripheral element of the facade glazing between the main reflector or the support part is part of the surround and the frame of the common housing, the frame of the common housing surrounding the element among the main reflector or the support part the less at the edge of the facade glazing (especially adjacent to the central area).

The frame of the common box is fixed to the rear face, under the mirror layer, directly or indirectly via one or more hanging profiles (brackets, etc.), in particular L-shaped, preferably made of metal, by a double-sided, watertight adhesive. liquid water, with a thickness greater than 0.6 mm fastening on the periphery or at least along the two opposite walls of the joint housing, (said hooking walls). The invention makes it possible to efficiently illuminate various light patterns on the back of a mirror and to close the product completely or sufficiently to hide the lighting system (LED + transformer ...) and protect it from water. In addition to allow more freedom for architects and designs, hotel rooms for example, the lighting solution is flexible adapting to the reasons requested. The diodes are laterally offset from the scattering pattern so as not to favor important hot spots. The diodes are not fixed to the bottom reflector to emit direct light that is too dazzling but to the support piece, lateral to the diffusing pattern.

The double-sided adhesive forms a first seal for the implantation of the mirror in a body of water (bathroom, kitchen, etc.). The double-sided adhesive between the facade glazing and the surrounding and possibly between the profile and the plate bottom reflector (spacer-type surround) also ensures efficient mechanical maintenance in a simple way because unlike a Glue is not likely to flow into the internal space at the risk of deteriorating the reflection of light rays and dropping efficiency Its application is also cleaner and sharper than glue. The double-sided adhesive is also more effective for fixing and sealing than a UV adhesive or even two-component too thin, irregular thickness.

The thickness of the double-sided adhesive is calibrated and a minimum thickness has been determined so that the fixing of the housing is resistant to humid atmospheres so that the product is robust. According to the invention, the double-sided adhesive and even the dedicated or common housing can meet the IP 44 standard of sealing well-known liquid water and even dust so protected against solid bodies greater than 1 mm, and protected against splashing water from all directions. The double-sided adhesive is preferably present on at least two preferably longitudinal edges of the dedicated housing (of the entourage) or common, on three edges on four edges and or even frame all the case to be fixed to the rear face.

The double-sided adhesive is preferably a rectilinear strip including constant width and constant thickness. The double-sided adhesive may be applied to the surround (profile or box) or the attachment profile or profiles with a contact width of preferably at least 5 mm.

If the surround is a thin wall (less than 5mm) it may be preferable to apply the double-sided adhesive on the mirror layer and then bring back the entourage (section (s) or box) and the profile (s). hangs possible especially in the internal space. Preferably for an elongated pattern, for the dedicated case only one of the longitudinal edges of the entourage or two lateral edges of the entourage (opposite the lateral edges of the elongate pattern) may be joined by a putty and the other edges of the surroundings fixed by the double-sided adhesive, without recourse to the additional seal. When the double-sided adhesive is fixed on the back side (the mirror layer) rather than prefixed on the housing (surround) before assembly can be chosen the double-sided adhesive width of at least 10 mm and preferably of at most 20mm, adhesive protruding outside the case. One can choose a double-sided adhesive thickness of at least 0.8 mm even at least 1 mm for more precaution and preferably at most 2 mm. For an even more secure fixation of the case to the facade glazing, the double-sided adhesive between the surround and the facade glazing (directly and even via the attachment profile or profiles) has a contact width of at least 5mm and even at least 8mm. As double-sided adhesive there may be mentioned a strip, generally foam or cellular, with principal faces carrying adhesive, for example acrylic tape (with acrylic adhesive) or polyester tape or polyethylene. Preferably, according to the invention, when referring to a distance ("horizontal") of an element (diode emitting face, surrounding wall, box, base or profile return, mirror support, etc.) at the edge of the scattering pattern, the distance between the orthogonal projection of the element on the plane of the scattering pattern and the edge of the scattering pattern is considered. Preferably, to form a dedicated case sealed to liquid water, when the double-sided adhesive and the optional abutment seal is not around the perimeter of the dedicated housing, an additional sealing seal with liquid water mastic type complements the tightness of the dedicated housing, externally to the internal space and against the entourage, particularly in the case of an indirect fixation of the entourage via the (s) profil (s) hanging, seal then present on the separate walls of the hanging walls. Preferably, to form a liquid water-tight common housing and when the double-sided adhesive and the optional abutment joint are not around the perimeter of the joint housing, an additional sealing seal with liquid water sealant type completes the tightness of the common housing, externally to the internal space and against the common housing, particularly in the case of an indirect fixing via the (s) profiled (s) attachment attached to the walls separate hanging walls.

A liquid water sealing system of the dedicated or common housing may preferably consist of double-sided adhesive and any putty joints. Optionally, each attachment profile is fixed to a wall of the enclosure of the dedicated or common housing by a screw or nut passing through the wall, and a sealing washer, in particular made of rubber, is interposed between the wall and each attachment profile. liquid water sealing system of the dedicated or common housing may consist of said double-sided adhesive and possibly sealant (s) mastic (s), preferably preferably transparent silicone if surrounding visible through the thickness of the illuminating mirror .

Alternatively, one (or each) PCB is used with diodes sealed with liquid water, preferably at least according to the IP44 standard and, where appropriate, the parts forming the surrounding of the dedicated box or flanking the common box are in contact or spaced less than 1 mm apart. The PCB (s) can be liquid watertight (according to at least IP44 standard) by adding a nanolayer, or a transparent layer such as a silicone on the PCB (s) and the diodes or else an encapsulation (coating of the assembly) for example PVC (polyvinyl chloride). So the parts forming the entourage of the dedicated box or flanking the common box are then in contact or spaced less than 1 mm, possibly without joint (s) abutment between the parts, and the first PCB with the first group of diodes is watertight liquid preferably at least according to the IP44 standard. In the case of a common housing, the least peripheral element (preferably the support part) is preferably in contact or spaced less than 5 mm from the other part or parts.

Preferably for an elongated pattern, for the common box only one of the peripheral edges of the entourage or two lateral peripheral edges of the entourage (opposite the lateral edges of the elongated pattern) may be joined by a putty and the other edges of the entourage fixed by the double-sided adhesive, without recourse to the additional seal. The butt joint is recessed or at the edge of the diffusing pattern. The sealant, especially a silicone, is preferably at least 2 mm wide. The additional seal may come as a sealing reinforcement locally especially in case of recourse to the (x) profile (s) of attachment if the entourage in particular of lateral section I and / or is of small width typically less than 5 mm or less than 3mm or even 1.5mm. The additional seal may be a flexible seal made from a cartridge. It may be silicone for example white or transparent. An additional seal is preferred outside the surrounding area rather than under the surrounding area. The additional sealant seal is deposited after fixing the entourage. It can however spread under the edge of the case (of the entourage) while remaining in withdrawal or even the edge of the scattering pattern. If the surrounding of the dedicated housing or the side walls of the joint housing are in several parts, the butt joint may be preferably a silicone type sealant because the application is easy, touch-ups for sealing simple and secure corners .

The liquid water sealing system for a monolithic surround may be a double-sided adhesive around the periphery of the diffusing pattern prefixed to the surround or if the slice (the thickness) of the surrounding is fine, of not more than 3mm, double-sided adhesive prefixed on the back side (on the mirror layer). In a simple design, the sealing system of the dedicated or common housing consists of said double-sided adhesive, such as a support (foam) with two acrylic adhesive faces, and possibly a sealant seal such as silicone, including the possible abutment joints of the entourage. In an advantageous design, the dedicated box or the common box is attached to the rear face (under the mirror layer) with the double-sided adhesive except at least in a shaped edge of the facade glazing (of the slice). In this (each) shaped edge, the dedicated housing or the common housing is bonded to the rear face by a seal which is a putty, said border seal, facade glazing including at most 2mm or even d at most 1 mm, the dedicated or common housing having a wall of thickness less than or equal to the shaping width joined by the edge seal to the rear face, the edge of the pattern diffusing along the edge seal preferably being less than 3 mm, and even at most 1 mm from the shaped edge and even to the shaped edge. It is preferred that the wall under the shaped edge be devoid of diodes to avoid hot spots because the diodes would be very close to the edge of the scattering pattern. This wall under the shaped edge is preferably of rectangular or L-shaped section with a base and a single return plate reflector bottom. The edge seal is preferably transparent and / or preferably silicone.

The shaping may be: - cut-to-square, round or square notch - with cut edges or bevelled edge; or grinded or grinded ground or grind smooth or polished with a matte (satin) or polished slice for example according to EN12150 - or a shaping like a chamfer, a bevel. The width of the shaped edge can be at most 4mm and even 2mm or 1mm. The edge seal may preferably be along a lateral edge of the elongate diffusing pattern. It is even possible to provide two edge joints along the two lateral edges of the elongate diffusing pattern. For a frame pattern, the border seal may be on all or a fraction of a small side of the frame pattern or even two small sides of the frame pattern. The border seal may be along a longitudinal edge of the elongate diffusing pattern or frame.

For an elongated pattern, the edge seal may be a fraction of a longitudinal edge preferably less than half the length L1 to provide greater comfort of attachment by the double-sided adhesive. One longitudinal edge can be alternated: U-section with double-sided adhesives (bottom plate reflector side, facade glazing side) / L-shaped profile with edging under the shaped edge and double-sided reflective side adhesive from bottom to plate. For a frame pattern, the border seal may be a fraction of a large side of the frame preferably less than half the length of the long side to have enough attachment by the double-sided adhesive.

Then, a liquid water sealing system of the dedicated or common housing is preferably said double-sided adhesive and the or any abutment joints of the entourage, including silicone, and the edge seal (or the border seals preferably lateral) including silicone.

The double-sided adhesive is recessed or at the edge of the diffusing pattern. The double-sided adhesive may preferably exceed at most 10 mm better 5mm of the entourage (profile (s) or side of box) if the one or more hooks profiles are in the internal space. The main reflector may be oblique as in the prior art. For example for the reflection of the central rays, it can form an acute angle of 20 ° to 60 °, especially 30 ° to 50 ° relative to the rear face. However, it is preferred that the main reflector has a normal N forming an angle of not more than 10 °, better not more than 5 ° with the plane of the facade glazing and not more than 10 ° with the plane of the bottom reflector And more widely than: the surrounding or the common case (and the support part inside for example) has one or internal walls which have a normal N forming an angle of at most 10, better not more than 5 ° with the plane of the facade glazing and at most 10 ° with the plane of the bottom reflector, and preferably the first PCB has a normal N forming an angle of not more than 10 ° better than 5 ° with the plane of the facade glazing and not more than 10 ° with the plane of the bottom reflector. This simplifies the manufacture of the case in the case of several profiles. In addition, a straight section is narrower than an oblique profile can make it possible to produce diffusing patterns closer to the edge of the facade glazing. This invention allows for very diverse patterns. If the thickness H remains less than 50mm, the lighting system is not easily visible from the outside. The entourage can play the role of support and heat sink for the LEDs, if metallic. The entourage may be in one piece or in several sections and forming a spacer between a flat plate bottom reflector and the facade glazing. The surround and the bottom reflector can also form a monolithic metal box.

The entourage can follow the contour of the diffusing pattern: elongated pattern in rectangular or square band, in L etc. In the same way, a plate (metallic, transparent with reflective layer) having a portion forming the bottom reflector may follow the contour of the diffusing pattern or extend to form bottom reflector of at least one other scattering pattern. The surround may include one or more profiles: - in particular with a base and a return towards the internal space on the rear side of the facade glazing, back indented or on the edge of the diffusing pattern or opposite the diffusing pattern of not more than 5mm from the edge of the pattern - and / or a spacer of rectangular or square section devoid of recessed diodes or on the edge of the diffusing pattern or opposite the diffusing pattern of not more than 5mm from the edge of the pattern .

Thus, on the bottom reflector side, the possible return (s) of the profile (s) of the entourage or profiling (s) of attachment of the entourage preferably exceed at most 5mm on the bottom reflector facing the diffusing pattern. On the rear side of the facade glazing, the possible return (s) of the profile (s) of the entourage or profiling (s) of attachment of the entourage preferably do not exceed the rear face on the diffusing pattern. It is preferable to fix the mirror illuminating from behind and masked (mirror support not exceeding the edge) as opposed to a frame around the edge of the edge of the facade glazing or a frame or profile with a return to the face before. This preserves the front face. More broadly, the front face is preferably devoid of masking element or fixing the illuminating mirror (screw, return of a frame of the illuminating mirror, etc.), walking or hollow macroscopic at least lpm and even the slice is preferably devoid of fastening element or even masking. The front face may be a free surface optionally entirely coated with one (or more) functional thin layer. Preferably on the face opposite to the rear face of the pattern diffusing the front face is free. The mirror can be attached to a wall at a piece of furniture. The bottom reflector is preferably separate from a wall or a furniture wall (even glass or metal).

It is then preferred to form a dedicated or common sealing case before assembly for better control. The mirror support can therefore be devoid of any protruding part of the edge of the facade glazing and is chosen from: one or more profiles fixed to the rear face, preferably metallic and / or a plate (preferably metal) fixed by bonding or mechanically on the outer main surface of the bottom reflector and with a fixing means (hook, retaining means, etc.), possibly fixed by a screw or nut passing through the bottom reflector, a sealing washer with liquid water being then preferably interposed between the plate and the bottom reflector. The mirror support in particular forming: - a monolithic frame in the central zone of the mirror and / or peripheral of the mirror, in particular distinct from the dedicated or common sealed housing, frame spaced or attached to the housing - several profiles including frame (two, three or four straight profiles spaced or abutted) in the central zone of the mirror and / or peripheral of the mirror, in particular with at least one profile separate from the dedicated waterproof housing (of the entourage) or of the common housing, spaced or attached and / or optionally least one profile serving for the entourage - and / or two lateral or longitudinal profiles to the facade glazing possibly serving for the entourages of several diffusing patterns. It may be preferable to leave a free space in the central area to place a non-condensing heating element of the mirror layer.

The bottom reflector may be of any shape rectangular or round or square. It can be a metal frame or plastic or glass all around the facade glazing to serve for several diffusing patterns and leave in the center space for attachment to a wall. The mirror support is for example spaced or attached to the outside of the entourage and / or the dedicated or common housing, in particular with a hooking aperture sufficiently offset from the bottom reflector for attachment to a fixing wall (furniture, Wall). The mirror support may have an attachment aperture in a plane parallel to the rear face or normal to the rear face. The fixing wall (wall or furniture) may have one or more fastening hooks.

It may be desired to use in particular use profiles for the entourage that are not strong enough to participate in fixing the mirror, being too thin typically. Preferably, for a secure fixation of the illuminating mirror, the mirror support is fixed by a double-sided adhesive to the rear face of the facade glazing, on the mirror layer. Preferably the width of the adhesive, on the mirror layer, is at least 10 mm and preferably a thickness of at least 1 mm. A simple double-sided adhesive of identical nature (or similar) is preferably chosen for the double-sided adhesive for fastening the dedicated or common box to the facade glazing. In a first embodiment, the bottom reflector is a plate (flat or concave towards the facade glazing, without returns against the rear face), the mirror support comprises a profile which forms a wall of the dedicated or common housing and corresponds to the support piece or the main reflector or another part of the entourage, including a U-section straight section or closed type of square or rectangular. The mirror support is fixed by a double-sided liquid-tight adhesive with a thickness greater than 0.6 mm on the bottom reflector, preferably identical (or similar) to the double-sided adhesive for fixing ( its fixation) to the facade glazing.

This mirror support has at least one portion or end protruding from the bottom reflector (under the rear face, on the mirror layer) for fixing the illuminating mirror to a wall (better two projections or ends protruding from the bottom reflector are provided on two opposite edges of the bottom reflector). The profile is preferably metal (aluminum etc.) at least 1.5 mm thick.

The double-sided adhesive between the mirror support and the bottom reflector may have a width (of contact with the bottom reflector) of at least 10 mm and in particular identical to that with the facade glazing and even a thickness of at least 1mm. In this embodiment we take advantage of the mounting profile to form the housing or even the support part. This profile may be more peripheral than the diffusing pattern or in the central area of the mirror. In a second embodiment, the bottom reflector is a plate (flat or concave, without return on the rear face), the mirror support forms a wall of the dedicated or common housing and corresponds to the support piece or to the main reflector or to a Another part of the entourage, in particular is a profile (right) section U or closed rectangular or square type. This mirror support is against or even connected to the edge of the bottom reflector (in a liquid watertight manner). This mirror support can be fixed by a liquid-tight adhesive on the edge of the bottom reflector, in particular glue or double-sided adhesive preferably identical (or similar) to the double-sided adhesive for fixing to the glazing facade. The mirror support may also be against the edge of the bottom reflector and is added a sealant (such as silicone) preferably identical to the butt joint.

The term wall for the bottom reflector is taken in the broad sense, and does not imply a minimum thickness. It can be a movie or a sheet. The wall may be flexible or rigid, mineral or organic. The term plate for the bottom reflector is taken in the broad sense and does not imply a minimum thickness. It can be a film or a leaf, it can be flexible or rigid, mineral or organic. For a better mechanical strength, however, a rigid wall is preferred for the bottom reflector (bottom of a box or plate). It is also preferred for heat resistance even better a mineral glass plate less than 6mm thick and at least 0.5mm and even 2mm.

As already said, the entourage can act as a spacer between the facade glazing and the reflector. For example, the bottom reflector being: a transparent plate (plate preferably flat or concave towards the internal space) made of mineral or plastic glass with the bottom reflective layer (inner face or outer face) or a metal plate (aluminum etc.) optionally coated with a reflector including diffuse reflection -or a wall or furniture wall (flat or concave towards the internal space) as a wooden board (solid, laminate) with the reflective layer including diffuse reflection on the space side internal, all or part of the entourage being fixed to the bottom reflector by a double-sided waterproof adhesive with liquid water greater than 0.6 mm thick preferably identical (or similar) to the double-sided adhesive for fixing to the facade glazing.

Each double-sided adhesive may preferably have a width (in contact with the bottom reflector or the facade glazing) of at least 5 mm and preferably at least 10 mm (with the front glazing) if mirror support. And in a preferred embodiment for its simplicity and flexibility, the support part, preferably metal, is selected from: - a hollow or solid spacer including rectangular or square side section, between the front glazing and the bottom reflector carrying the first PCB, spacer of thickness greater than or equal to 5 mm and preferably not more than 15 mm, and fixed by the double-sided adhesive to the bottom reflector preferably identical (or similar) to the adhesive double-sided for fixing to the facade glazing, and / or a preferably U-shaped part, or Z or H turned to 900, which comprises a bearing base of the first PCB and on both sides of the base at least the first and second returns (returns with identical orientations to the internal space or the opposite of the internal space, or with opposite orientations), returns each width greater than or equal to 5mm and preferably d not more than 30 mm: - the first preferably metallic return oriented towards the internal space being between the base and the facade glazing and fixed by the double-sided adhesive and the second preferably metallic return facing towards the inside. internal space being between the base and the bottom reflector and fixed by the double-sided adhesive preferably identical (or similar) to the double-sided adhesive for attachment to the facade glazing, and / or a piece of I (Rectangular or Square Side Section) which has a carrier base of the first PCB, (Rectangular or Square Side Section) an L-shaped L-Profile Mechanically Fastened to the Base and secured by the Double Sealant -face to the facade glazing (under the mirror layer), and another L-shaped attachment profile mechanically fixed to the base and fixed by the double-sided adhesive to the bottom reflector, each section having a width greater than or equal to 5 mm and preferably d not more than 30mm - or alternatively a U-shaped attachment profile mechanically fastened to the base and fixed by the double-sided sealing adhesives (thickness greater than 0.6mm) to the façade glazing and the bottom reflector preferably identical (or similar), profiled width greater than or equal to 5mm and preferably at most 30mm. And / or the main reflector, preferably metallic, is chosen from: - a hollow or solid spacer, in particular of rectangular or even square lateral section, between the front glazing unit and the bottom reflector, spacer having a thickness greater than or equal to 5 mm and preferably at most 15mm, and fixed by the double-sided adhesive to the bottom reflector preferably identical (or similar) to the double-sided adhesive for attachment to the facade glazing - and / or a piece preferably in U, or Z or H turned to 900, which comprises a possible bearing base of a PCB and on either side of the base of the first and second returns (returns with identical orientations to the internal space or to the opposite of the internal space, or with opposing orientations), returns each of width greater than or equal to 5 mm and preferably of at most 30 mm: the first metal preferably return and oriented towards the internal space being between base and the facade glazing and fixed by the double-sided adhesive and the second preferably metallic return and oriented towards the inner space being between the base and the bottom reflector and fixed by the double-sided adhesive preferably identical (or similar) to the double-sided adhesive for fixing to the facade glazing - and / or an I-shaped part, of rectangular or square lateral section in particular of thickness less than 5 mm and even to 3 mm or 1.5 mm, which includes a base possibly carrying a PCB with diodes, (base without return) and: - an L-shaped attachment profile mechanically fixed to the base and fixed by the double-sided adhesive to the facade glazing (under the mirror layer), and another L-shaped attachment profile mechanically fixed to the base and fixed by the adhesive to the bottom reflector, each section having a width greater than or equal to 5 mm and preferably not more than 30 mm - or alternatively a U-shaped attachment profile canically at the base and fixed by the double-sided adhesives (thickness greater than 0.6mm) front glazing and reflector bottom preferably identical (or similar) profiled width greater than or equal to 5mm and preferably d at most 30 mm.

In the case of a pattern close to the shaped edge, as already said, the main reflector may comprise or consist of an L-shaped section with a base (forming the wall joined by its edge) and a return to the internal space secured by the double-sided adhesive preferably identical (or similar) to the double-sided adhesive for attachment to the facade glazing. Preferably the width of the double-sided adhesive in the other areas (without shaped edge) is at least 5mm for a more robust attachment. Preferably the surround (in particular of the dedicated housing), preferably metal, is formed of sections which are chosen from: a hollow or solid spacer, in particular of rectangular or square lateral section, between the front glazing unit and the bottom reflector, spacer thickness greater than or equal to 5 mm and preferably not more than 15 mm, and fixed by the double-sided adhesive to the bottom reflector preferably identical (or similar) to the double-sided adhesive for fixing to the facade glazing and / or a preferably U-shaped piece, or Z or H turned to 900, which comprises a possible carrier base of a PCB and on either side of the base of the first and second returns (returns with orientations identical to the internal space or the opposite of the internal space, or with opposite orientations), returns each of width greater than or equal to 5 mm and preferably of at most 30 mm: the first preferably metal return the inner space being between the base and the facade glazing and fixed by the double-sided adhesive and the second preferably metallic return and oriented towards the internal space being between the base and the bottom reflector and fixed by the double-sided adhesive preferably identical (or similar) to the double-sided adhesive for attachment to the facade glazing - and / or an L-shaped part, of rectangular or square lateral section, in particular of thickness less than 5 mm and even 3mm or 1.5mm, which includes a base possibly carrying a PCB with diodes, (base without return) and: - an L-shaped rail fastened mechanically to the base and fixed by the l double-sided adhesive to the façade glazing (under the mirror layer), and another L-shaped attachment profile mechanically fastened to the base and fixed by the double-sided adhesive to the bottom reflector, each section having a greater width or equal to 5mm and preferably not more than at 30mm - or alternatively a U-shaped attachment profile mechanically fixed to the base and fixed by the double-sided adhesives (thickness greater than 0.6mm) to the facade glazing and the bottom reflector preferably identical (or similar ), profile width greater than or equal to 5mm (to prefix the double-sided adhesive) and preferably not more than 30mm The support of the mirror may be spaced or attached to the outside of the environment (of the room support, the main reflector, a lateral reflector) and / or the dedicated or common housing or be part of one of the profiles of the entourage (of the support part, the main reflector, a lateral reflector).

The advantage of a rectangular or square section spacer for the main reflector (or so-called lateral reflectors on lateral edges of an elongated pattern) is that it can be as far as possible at the edge of the diffusing pattern. This is particularly useful when the main (or lateral) reflector is devoid of diodes, source of hot spots.

The width of at least 5mm of the double-sided adhesive on the facade glazing and the bottom reflector allows a robust attachment. The width of up to 25mm of the double-sided adhesive on the facade glazing and the bottom reflector allows a greater freedom of design of diffusing patterns. When the profiles have contact with the facade glazing or the reflector less than 5 mm, one or more attachment profiles are preferably used. The advantage of a profile with a return directed towards the inner space and mirror layer side for the support piece (or reflectors on lateral edges of an elongated pattern carrying diodes) is that the return can reflect the lateral light instead of going on the protective layer of the silver layer. One can even place the return along the edge of the diffusing pattern, preferably with a base capable of sufficiently moving the diodes away from the edge of the diffusing pattern to avoid hot spots. In another embodiment: the dedicated housing comprises a metallic monolithic housing optionally shiny or coated with a diffusing reflective layer (white reflector, white paint or lacquer, etc.) or plastic coated with a reflecting layer, preferably by diffusion (white reflector, paint or white lacquer), whose bottom is the bottom reflector and flanks (walls) said surround of the scattering pattern; OR - the common box comprises a metallic monolithic box optionally shiny or coated with a reflective layer (reflector white paint or white lacquer) or plastic coated with a reflective layer preferably by diffusion (reflector white paint or white lacquer), including the bottom is the bottom reflector and the flanks (walls) said surround of the diffusing pattern, and the power supply, of the first PCB, in particular along an inner edge of the diffusing pattern, and possibly another diffusing pattern , another PCB on another support piece on an inner edge of the other particular diffusing pattern, the mirror support being optionally attached to the outer face (opposite to the inner space) of the bottom reflector preferably without breaking the sealing therefore preferably by a double-sided adhesive (in the case of slots it is preferably sealed with a double-sided adhesive as already described) . It is preferred that the box has: - one or more returns to the internal space (or the opposite) of at least 5mm for fixing and sealing by the double-sided adhesive (exclusively) - and / or a contact width external to the internal space of at least 5mm for fixing and sealing by double-sided tape (exclusively). Alternatively, the dedicated or common box comprises a monolithic box, metal or plastic coated with a reflective layer, the box (the surrounding for the dedicated box) including I-section, thickness or width of connection with the face rear less than 5mm in particular of not more than 2mm (possibly with side (s) or wall (s) under bors (s) shaped (s) of the front glazing), box being attached to the rear face, under the mirror layer directly by the double-sided adhesive on its edge and indirectly via at least two fastening profiles, in particular L, in the internal space, with the double-sided adhesive (on their edges), along with minus two walls or opposite sides of the box (of the entourage), the double-sided adhesive preferably forming a sealing frame alone or with a putty including a border seal (side of the box without a hanging profile under edge shape).

We can prefer a fixing by three or four sides of the box for example with three or four profiles (one profile per sidewall). The edge seal is deposited after fixing the entourage it avoids more easily that it overflows on the scattering pattern nearby.

It is preferred to fix the illuminating mirror on at least two sides rather than for example on the top of the glazing to prevent the user by manipulating the mirror does not destabilize. According to the invention, the term "element (fixing support, surround, in particular box or profile, etc.) on the mirror layer is an element directly on the so-called mirror metal layer or preferably directly on a protective layer (paint, etc.) covering the mirror layer. Preferably, the diodes each have an emitting face whose projection orthogonal to the plane of the diffusing pattern is at a distance of at least 5 mm, 10 8 mm better of at least 10 mm and even 12 mm from the (nearest) edge of the pattern diffusing and less than 50mm and even less than or equal to 40mm. The remoteness of the diodes from the diffusing pattern makes it possible to limit the hot spots of the LEDs to large angles for the user while keeping the illumination of the diffusing zone effective while not moving too far. The surround (and / or the other surround) preferably comprises one or more internal walls (base of a profile) whose orthogonal projection on the plane of the diffusing pattern is at a distance less than 10 mm from the edge closer to the diffusing pattern and possibly at most 5mm in the zone or zones without diodes. The entourage (and / or the other entourage) comprises for example: 20 - one or profiles optionally devoid of diodes, in particular L or U, with facade glazing side a return towards the internal space, back recessed not more than 5 mm, preferably at the edge of the pattern diffusing or protruding from the edge of the diffusing pattern of not more than 5 mm, and / or the (or each) fastening profile in the internal space and devoid of 25 diodes , has facade glazing side, a return towards the internal space, back indented of not more than 5mm preferably or the edge of the pattern diffusing or protruding on the edge of the diffusing pattern of not more than 5mm, - and / or a wall or flank of a box of rectangular or square section or a spacer of rectangular or square section, flank or spacer devoid of 30 diodes, recessed by at most 5 mm preferably or at the edge of the pattern diffusing or protruding on the edge of the diffusing pattern of not more than 5mm. Thus, on the bottom reflector side, the possible return (s) of the profile (s) of the entourage or profiling (s) of attachment of the entourage preferably exceed at most 5mm on the bottom reflector facing the diffusing pattern.

Rear side of the facade glazing, the possible return (s) of the profile (s) of the entourage or profiling (s) of attachment of the entourage does not exceed (s) preferably of the back side on the motive broadcasting. The choice to create an optimized remote surround of the diffusing pattern guarantees the best efficiency. The diodes are positioned judiciously around the pattern, the lighting is very homogeneous up to a pattern width of 230mm. In particular, the width (maximum) (constant or variable width) of the first illuminating zone (of any possible shape) may preferably be less than 200 mm or even less than or equal to 180 mm, in particular to leave a mirror area surface (central) important. The diodes are positioned to form a continuous illuminating area along the length of the scattering pattern. The "intra-group" distance between adjacent diodes of the first group may preferably be the same for all the diodes to simplify beam overlap.

The bottom reflector, positioned opposite the diffusing pattern against the surround, creates a closed light box to diffuse light from the LEDs onto the diffusing pattern area of the mirror. If the bottom reflector is large enough for example of the same size as the mirror, it hides the complete lighting system (LED and transformer) placed at the back of the mirror. If the bottom reflector is a flat plate that extends beyond the surroundings of the diffusing pattern, it is preferred that it be a glass plate (textured and / or coated) or even plastic rather than metallic (and can be coated). The choice to make a dedicated case for a pattern diffusing in a restricted area of the total surface of the glazing is more economical than a "total" housing substantially covering the rear of the facade glazing, in particular for large mirrors of at least 500mm in length. Preferably the distance between the main reflector and the slice of the plate bottom reflector is at most 10 mm and even at most 5 mm. Preferably, the width of the common box is less than 70% better than 50% of the width of the facade glazing. The choice of making a common box in a restricted area of the total surface of the glazing is more economical than a "total" housing substantially covering the rear of the facade glazing, in particular for large mirrors of at least 500 mm length. Just 30mm wide to house the power supply (transformer connector etc).

It is preferred that the scattering pattern be off-center, that the mirror be kept in the central area by at least 500mm by 500mm. The inner edge is spaced preferably at least 200mm from the middle of the facade glazing. The peripheral zone between the outer edge and the edge of the facade glazing with mirror is at least 25 mm. From a dimensional point of view, at least one of the following characteristics can be provided: the width of the diffusing pattern is width less than 30% of the width of the facade glazing (even 20% or 10%), the length of the diffusing pattern is at least 50 mm, better still at least 100 mm and even 200 mm in particular, substantially equal to the length of the lateral or longitudinal edge of the corner facade glazing (square, rectangular, etc.), - the length of the surround and the bottom reflector is at least equal to the length of the diffusing pattern, - the length of the surround and the bottom reflector is at least 50mm and in particular, substantially equal to the length of the lateral or longitudinal edge of the facade glazing, with corners (square, rectangular ...), - for an elongated pattern, the diode end of the first group (and the second group) is at least 1cm of the first lateral edge of the diffusing pattern and the other end diode of the first group (and the second group) is less than 1cm from the second side edge of the scattering pattern. It is preferred that the surround has no wall connecting the main reflector to the diode support part or any other wall under the diffusing pattern. The edges (internal and / or external) of the scattering pattern may be straight or curved. It is preferred that the entourage is based on straight profile (s) extending rectilinear optionally bent L or U (forming a sealed frame by abutting and jointing). For simplicity, the entourage (preferably for the dedicated case) may be of rectangular outline and / or follow the contour of the pattern diffusing preferably by means of profiles (preferably metallic) U-section and / or L-shaped sections in particular butted or spaced less than 1 mm or jointed by butt joint Preferably a central mirror area is preserved over at least 30% or even the majority of the surface of the facade glazing, still 60 or even 80%. The main reflector may be a metal wall (with or without a coating), in particular with a light reflection RL greater than or equal to 70% better than 80% or matt (diffuse reflection). The wall can be matte, metal (aluminum etc) raw, or polished by polishing for example or rough (frosting, sanding etc.). Typically, the side wall of an aluminum box (anodized) or an aluminum section (anodized) reflects enough but we can add a white reflector or a shinier metal layer or polish or texturize its surface at the same time as the bottom wall (of a box etc) is covered. The main reflector may be a metal wall, coated with a main reflecting layer which may be, by specular or diffusing reflection, for example: a metal layer, generally specularly reflective, glossy or matte, for example a silvering on glass, on the inner space side - a diffuse reflection layer, usually white: enamel, lacquer, paint, for example essentially titanium oxide-based, on the inner space side.

The main reflector may be a transparent, plastic wall (PMMA for polymethyl methacrylate, for example polycarbonate), in particular of thickness from 1 mm to 5 mm, or even in glass, wall coated with a main reflecting layer which may be, by reflection specular or diffusing, for example: - a metal layer, generally specularly reflective, glossy or matte, for example a silvering on glass, on the side of the internal space or the opposite side - a diffuse reflective layer, usually white: enamel , lacquer, paint, for example substantially based on titanium oxide, the side of the internal space or the opposite side.

A layer may be diffuse reflection and specular, for example with a coefficient in diffuse reflection equal to at least 0.8 times the coefficient in specular reflection. The bottom reflector may be a metal wall (with or without a coating), especially with a light reflection RL greater than or equal to 70% better than 80% or matt (diffuse reflection). The wall can be matte, metal (aluminum etc) raw, or polished by polishing for example or rough (frosting, sanding etc.). The bottom reflector may be a metal wall, coated with a main reflecting layer which may be, by specular or diffusing reflection, for example: a metal layer, generally with specular reflection, glossy or matte, for example a silvering on glass on the inner space side - a diffuse reflection layer, usually white: enamel, lacquer, paint, for example essentially titanium oxide-based, on the inner space side. This layer may be diffuse reflection and specular for example with a coefficient in diffuse reflection equal to at least 0.8 times the coefficient in specular reflection. The bottom reflector may be a transparent wall, plastic (PMMA, polycarbonate), for example wall thickness of 1mm to 5mm, or even glass, for example of thickness less than 6 mm, even at 5mm, coated with a reflective background layer which may be, by specular or diffusive reflection, for example: a metallic layer, generally specularly reflective, glossy or matte, for example silvering on glass on the side of the internal space or the opposite side, - A diffuse reflective layer, usually white: enamel, lacquer, paint, for example mainly based on titanium oxide on the side of the inner space or the opposite side.

This layer may be diffuse reflection and specular for example with a coefficient in diffuse reflection equal to at least 0.8 times the coefficient in specular reflection. The wall of the bottom reflector may be a plastic film such as a fluoropolymer film, in particular FEP (Fluorinated ethylene propylene in English), ETFE (ethylene-co-tetrafluoroethylene) in English). The bottom reflector in the form of a transparent plate with a specular or diffuse reflecting layer preferably has a light transmission of less than 15% and even 10% of the opposite side to the internal space. In particular, it is possible to envisage as a bottom reflector a transparent wall (glass or even plastic), in particular a glazing unit or the bottom of a transparent box (planar or concave), with: - on the opposite side to the internal space a reflective layer diffuse white: enamel, lacquer, paint, qualified as a white reflector - or on the internal space side a diffuse white reflection layer: enamel, lacquer, paint, qualified as a white reflector, with a TL of at least 20% or even 30% and the opposite side to the inner space, a specular reflection layer like a silver mirror.

A reflective layer is preferred on the opposite side to the inner space. Deposited on the outer face of the transparent wall (preferably flat plate or bottom of the transparent box) the LED light passes through the thickness of the wall before being diffused by the reflective layer. This allows certain light rays to be guided by the transparent wall to be diffused further and thus contribute to the homogenization of the illumination of the pattern. With a white reflector on the back, the colors are also better reproduced. The color temperature on the mirror is closer to that of the LEDs. Typically, the surround may be formed by folds and / or curvatures of a metal sheet possibly coated with a white reflector and / or by molding and / or by extrusion of a plastic. When the dedicated case is formed of a transparent case in a pastic with a reflective layer or preferably chooses as polycarbonate plastic or PM MA. The illuminating mirror can be placed on a wall of a piece of furniture or a wall that then forms the bottom reflector like a white wall, a piece of white wood furniture. However it is preferred to make the waterproof housing before assembly for better control of the sealing and positioning. The diffusing pattern is arranged on the rear face to be protected and the front face preferably in contact with the external environment can be smooth and easily cleaned. The diffusing pattern is preferably formed by surface texturing of the glazing, in particular sandblasting, acidizing, abrasion or by adding a diffusing element, especially in a layer, preferably by screen printing of an enamel or a diffusing layer or formed from a diffusing plastic material. If the diffusing pattern is enamel, acidification is formed the diffusing pattern on a glazing with a partial mirror. The sanding allows him to remove the mirror (painting and silvering). Acid etching, sandblasting, etching (advantageously by laser) or screen printing may be preferred because providing a delineation of the treated areas easily controllable and reproducible industrially.

Acidic glass includes the SAINT-GOBAIN GLASS Satinovo® glass and the SAINT-GOBAIN GLASS Smoothlite® diffuser glass. The glazing (bare) can have a TL of at least 70%, or even at least 80%. The glazing can be made of clear or even extra-clear mineral glass. For extra-clear glass; reference can be made to application W004 / 025334 for the composition of an extra-clear glass. In particular, it is possible to choose a silicosodocalcic glass with less than 0.05% of Fe III or Fe 2 O 3. We can choose, for example, the SAINT-GOBAIN Diamant® glass, the SAINT-GOBAIN® Solar Glass®, the SAINT-GOBAIN® Albarino® glass (textured or smooth), the Pilkington OptiVVHITE® glass, and the Schott B270® glass.

In addition, a mineral glass is preferred for glazing for its many advantages: - the glass having a good resistance to heat, it can be close to the diodes despite the fact that they constitute hot spots, - the glass is mechanically resistant so that it is easy to clean and does not scratch, which is of particular interest for panels installed in locations imposing strict hygiene, - glass meets the requirements of fire safety standards. It may be as an example, depending in particular on the aesthetic rendering or the desired optical effect and / or the destination of the mirror: - glass of standard composition, such as Planilux® glass from SAINT-GOBAIN GLASS , of slightly green coloring, - extra-clear glass without coloration (neutral) such as Diamant @ and Diamant Solaire @ glasses of the company SAINT-GOBAIN GLASS, The diodes of the first group, notably substantially aligned, are (regularly) distributed over a PCB printed circuit board (for "Printed Circuit Board"). It is made of plastic or is metallic. Most often, a bar is metallic. The PCB may be of any shape, for example flat, in particular a strip, for example rectilinear of square or rectangular cross section. The use of such a support with its connection circuits already simplifies the manufacture, maintenance of the mirror and further limits the scrap rate. For even better light efficiency, the first PCB can carry a free surface (flat or inclined) around the first group of diodes and diffusing, for example diffuse reflection layer which is a lacquer or paint.

According to one characteristic, the diodes can be encapsulated, that is to say include a semiconductor chip and an envelope, for example epoxy resin type or PMMA, encapsulating the chip. The functions of this envelope can be multiple: wavelength conversion, scattering element.

The diode may be for example a semiconductor chip of the order of one hundred pm or mm; and possibly with a minimal encapsulation for example of protection. It is not necessary to use optics such as lenses directing the light emitted by the diode to the privileged areas. The diodes can be embedded in a common protective material (waterproof, dustproof ...). Preferably, the diodes can thus be simple chips or with a low volume encapsulation of the SMD type ("Surface Mounting Device" in English) or "Chip on Board" rather than the conventional, (first generation) voluminous diodes. low power and luminous efficiency.

From a dimensional point of view, one can provide at least one of the following characteristics for the diodes: the diodes are less than 1 cm high, or even 5 mm, the diodes are of width less than 1 cm the diodes are identical and regularly spaced from each other with an intra-group distance designating the distance between the axes of the successive diodes, possibly of the same order as the eigenvalues of the diodes, the number of diodes of the first group is at least equal to 10. The diode can be: - a diode "medium power" that is to say> 0.1 VV or brightness> or equal to 8 lumens, - a diode "high power" that is ie> equal to 1 VV or brightness> or equal to 80 lumens. The robustness of the diodes is particularly interesting in intensive applications such as in public transport such as trains, planes, coaches, pleasure craft .... The group or groups of diodes can be coupled to control means for to emit light either continuously, intermittently, with different intensities, or in a given color, or in different colors, especially depending on the amount of natural light. It can be provided that: - the length of the PCB is substantially equal to the length of the support part, - the first PCB is less than 1 cm thick better than or equal to 5 mm, - the first PCB is flexible and for example surrounds the diffusing pattern - the diodes and / or the PCB may be free of varnish or sealing encapsulation. A reflective surface for providing mirror function is usually a silver-based layer. The mirror may be the SGG Miralite product of the company SAINT-GOBAIN GLASS, with a protective paint to oxidation. The mirror according to the invention can include any other functional coating (anti-scratch, antifouling, etc.) on the back side of a heating layer for an anti-condensation effect. The lighting of the first illuminating area can be decorative, architectural, signaling or display. The illuminating and illuminating mirror may be particularly intended for: - the building, as a ceiling lamp, wall tile; a partition, - to a transport vehicle, in particular public transportation, train, metro, tramway, bus or aquatic or aerial vehicle (airplane), - street or urban lighting, - a window of street furniture, as a part of a bus shelter, a railing, a display, a display case, a shelf element, - an interior furnishing glazing, a bathroom wall, a piece of furniture. If necessary we can replace one or mirror areas outside the inner space of the entourage by one or decorative areas or even functional (switch etc). For example, a partially central partial mirror is formed and a decorative glaze (white, colored, etc.) is preferably used around the periphery. The diffusing pattern can therefore even be peripherally and surround by the mirror layer completed by the decorative layer (enamel etc.). It is preferred that the entourage remains masked by the mirror layer and / or the decorative layer as well as the attachment of the mirror to a wall. Other details and advantageous features of the invention appear on reading the examples of illuminating mirrors according to the invention illustrated by the following figures: FIGS. 1, 2, 3, 4, 5, 5 ', 6, 7, 8, 9, 9 ', 9 "are diagrammatic views, possibly partial, in section of a light-emitting diode illuminating mirror in various embodiments of the invention; FIGS. 1', 1a, 2 ', 2a, 3a, 4a, 5a, 5a, 5a, 6a, 6a, 7a, 8a, 9a to 9c, 9a to 9b are schematic front views (rear side) of the illuminating mirrors or housings; FIGS. 1a, 1b, 1c, 1d, 1c show examples of the scattering patterns and the arrangement of diodes on PCBs.

It is specified that for the sake of clarity the various elements of the objects (including angles) represented are not necessarily reproduced on the scale. FIG. 1 schematically represents a longitudinal sectional view of a light-emitting diode illuminating mirror 100 in a first embodiment of the invention.

The mirror 100 comprises a front glazing 1, made of flat mineral glass, for example a rectangular glass sheet, with a first main face 11 forming the rear face with lateral and longitudinal edges, and a second main face 12 forming the front face. , and a slice 13, glazing preferably less than 6mm thick, with a light transmission of at least 85%, such as the PLAN ILUX glass sold by the applicant company. The rear face 11 is coated with a metal layer 2 based on silver (made by silvering) called the mirror layer, giving the mirror functionality on the front face, with a light reflection RL of at least 85%, coated itself a protective layer (not shown), mirror layer present in particular in a central zone of the facade glazing, and at the periphery of the glazing. Take for example a glass with a partial mirror MIRALITE or MIRALITE EVOLUTION sold by the applicant company.

On the back side, a diffusing pattern 3 is adjacent to the mirror layer 2 in the central zone, the mirror layer surrounding the diffusing pattern preferably alone or optionally with a masking layer (decorative enamel, etc.). More specifically, it is preferred that the rear face 11 comprises the mirror layer with one or discontinuities formed or filled by the scattering pattern and even other scattering patterns. The diffusing pattern is capable of modifying the light transmission of the facade glazing 1, for example so that it is between 40 and 85% on the front side of the mirror. The diffusing pattern prevents too intense transmission of the rays (direct lateral or reflected by the bottom reflector in particular) emitted by the diodes, substantially reduce the glare of an individual looking towards the mirror 100. The facade glazing 1 with the 3 diffuse pattern has a blur of at least 80% preferably at least 90% or even 95% front side side of the mirror measured by Hazemeter in a conventional manner. The pattern diffusing on the rear face 11 of the glass is preferably obtained by texturing the glass preferably already coated with the mirror layer, in particular by sanding. The pattern can also be formed by acidifying the glass as produced for the SAINT-GOBAIN GLASS Satinovo® glass. Finally, the diffusing pattern 3 may be a diffusing layer (in this case a partial mirror is preferably made from the outset) preferably mineral essential, for example made by screen printing of an enamel (white) screen printing having the advantage of allow to obtain any type of design with well-defined boundaries. It may be an enamel such as that made for Smoothlite® glass from SAINT-GOBAIN GLASS or a Lambertian enamel for example as described in the example of application WO2012168647.

To form a light pattern, it is decided to place on the side of the rear face 11 a first group of inorganic light-emitting diodes 41 (or LEDs) along the longitudinal edge 31 preferably the innermost to the diffusing pattern 3. The choice of the inner edge avoids visual discomfort (low-angle hot spots, less than 10 °) when a person looks at the mirror in the central area at a short distance.

Preferably, for simplicity, the PCB 40 is parallel to the inner edge and all along the inner edge 31. The diodes are aligned, in a row, and evenly distributed on the first PCB 40, of the bar type (rigid or flexible ), rectilinear, in particular aluminum, and optionally with a diffusing layer around the diodes 41, for the recycling of rays, in the form of a white paint or lacquer.

It is preferred that the end diodes of the PCB be within 1cm of the side edges of the elongated pattern. For simplicity of assembly, the diodes 41 each have an emitting face perpendicular to the PCB 40 ("top emitting English") rather than a lateral side emission ("side emitting" in English). The first PCB 40 is carried (from the rear) by a profile said support piece 51. Here is inserted a thermal conductive fastening material 6 which is for example glue or double-sided adhesive tape to obtain even better thermal dissipation. The adhesive tape has the advantage of providing a calibrated thickness, allowing the PCB of the diodes to be perfectly flat and to ensure that the diodes are all equidistant from the reflector or scattering pattern. In addition, the adhesive tape allows its prior attachment to the PCB. It is also possible to use thermal grease between the PCB and the base, such as the compound CK4960® sold by Jetart.

The PCB 40 may be metallic. Then the diodes are soldered on tracks that are electrically insulated from the metallic material of the PCB. Since the metallic material of the PCB is thermal conductor, the PCB can be directly pressed against the thermal conductive base to achieve heat dissipation. Fixing the PCB to the base can then be carried out for example by clipping and / or screwing but it can retain a double-sided adhesive. The diodes 41 are SMD type or "Chip on Board" type. Each of the diodes 41 has a given emission spectrum in the visible, for example a white light, and with a main emission radius F, said first main ray, preferably forming an angle of less than 5 ° with respect to the glazing If the radius F is very inclined towards the mirror layer then the LEDs are more easily visible by the user. To facilitate homogeneity, the diodes are preferably chosen with the same (only) main direction of emission F. For uniform illumination, the diodes are chosen with the same spectrum in the visible, mono or polychromatic. We prefer a white or yellow light. The emission cone may preferably be symmetrical with respect to F. The emission cone may be, for example, lambertian. The beam of each diode is divergent and defined by a half-angle at mid-height of 60 °. The adjacent diode bundles of the first group overlapping on the surface of the scattering pattern.

The vertical distance e (normal distance to the facade glazing) between the emitting face and the rear face (the mirror layer) is preferably greater than 5 mm better than or equal to 10 mm in order to prevent the diode from heating the paint and silvering therefore degrades it.

The vertical distance ef (distance normal to the facade glazing) between the emitting face and the bottom reflector is preferably such that ei - ef 20mm even 10mm, in order to improve the homogeneity of the illumination. The radius F may preferably be centered. The distance e is for example substantially equal to the distance ef and between 15mm and 25mm.

In order to make the lighting effective and durable, a light-water-tight light-reflective box (according to the IP 44 standard) defining an internal space 14, dedicated to the diffusing pattern, is formed, comprising: a reflective surround surrounding the diffusing pattern; , of external length greater than or equal to length L1 and of external width greater than or equal to width VV1, reflective surround masked by the mirror layer and: - in several parts, profiled, spaced apart by less than 5 mm and joined by joints said butt sealants which are putty 63 and adhered by a liquid water sealing adhesive 61 which a double-sided adhesive tape to the facade glazing by the rear face 11, or alternatively a piece forming a monolithic frame (preferably of rectangular shape), - a bottom reflector in the form of a transparent plate 1 ', said bottom, such as a mineral glass pane or a plastic coated on the front face rear blade 11 'opposite the main face 12' facing the diffusing pattern 3, a reflective layer preferably diffuse reflective reflection 7, white, which is a lacquer or paint or an enamel, bottom reflector longer than the length L1 and width greater than the width VV1, bonded by a sealing adhesive 62 which is a double-sided adhesive tape with the surrounding, bottom reflector whose edge 13 'is vis-à-vis the slice 13 or preferably set back a few mm at least, - the facade glazing 1 in the area of the diffusing pattern 3, forming the cover of the sealed waterproof case. If the design of the pattern allows (as detailed later), it is preferred that the reflective surround forms a rectangular frame from two, three or four straight sections (preferably curved) and preferably of section (constant), of height (constant) and identical material. In fact one can choose as many profiles as sides of the diffusing pattern for example six profiles for an L etc. When the diffusing pattern is elongated, inscribed in a rectangular area; defined by two longitudinal edges and two lateral edges, the reflective surround comprises for example four identical U-shaped sections 51 to 54 with a base perpendicular to the facade glazing and on either side of the base two wings or returns oriented towards the internal space 14, therefore: - the support part 51, reflecting the light on both sides of the first PCB, with a base 5 perpendicular to the facade glazing and on both sides of the base two returns 5a , 5b oriented towards the internal space 14, - a said main reflector 52 positioned in front of the first PCB, - to laterally partition the light, first and second lateral parts 53 and 54 (see Figure la), along the side edges of the elongated diffusing pattern, for maximum recycling of light rays. The wing 5a of the support piece facade glazing side is fixed to the rear face 11 by the double-sided adhesive 61 which is a strip all along the support piece with a width of at least 5mm which is called width contact with the mirror layer (protected). The wing 5b is fixed to the bottom reflector 1 'by the double-sided adhesive 62, identical, for example with a contact width of at least 5mm. It is the same for the profiles 52 to 54. For simplicity we precolled each double-sided adhesive tape 61 on the wings facade glazing side before their attachment to the mirror layer. Then, after bonding, the four abutments are made.

The abutment seals 63 are for example silicone, white or transparent or even this double-sided adhesive again, but this is less easy to put in place. In a simple manner, each profile 51 to 54 of the reflective surround is: metallic, preferably of aluminum, anodized, rough, polished or optionally coated with a diffuse reflection layer around the diodes 2, for the recycling of rays, - or plastic, for example PMMA or PC, coated with a specular or diffuse reflecting layer for ray recycling, in the form of a white paint or lacquer on the inside or outside face.

In a simple manner, the reflective section 51 to 54 is straight metal, of U section, of thickness less than or equal to 3 mm even at 1 mm. Alternatively, the reflector profile 51 to 54 is PC or PMMA coated, straight, U-section, thickness less than or equal to 5mm.

The main reflector, the support piece, the first and second lateral parts flanking the diffusing pattern, preferably rectangular frame, and are spaced apart for example from a constant distance from the scattering pattern. Thus, the main reflector, the support piece, the first and second side pieces form with the front glazing and the bottom reflector a waterproof housing liquid water particularly suitable for a water room, a bathroom. The first PCB 40 does not need to have encapsulation, a tropicalization varnish for waterproofing. Alternatively, the profiles 51 to 54 are spaced less than 1mm are joined by butt joint and the PCB and the diodes are waterproof.

The double-sided adhesive on almost all the surrounding provides a satisfactory first level of sealing and maintains a robust and durable attachment. On the other side edge of the facade glazing 100 can be duplicated means to make a second efficient, homogeneous and durable light pattern: second scattering pattern, second PCB with the diodes, second reflective surround 51a 52a, second bottom reflector and that second fastening means and second sealing means (possible butt joints). The first PCB 40 comprises a power supply wire 91 coming out of the support piece 51 via an opening sealed by means of a cable clamp, wire leading to a connector 92 and to the connection wire of the second PCB for the second diffusing pattern. As shown in FIG. 1A, the second PCB (like the first PCB) is electrically powered via a feed wire 91 'leaving the support piece 51a of the second card via a sealed opening and connected to a resistant transformer 93 to the humid atmosphere. It is preferred to avoid making a surrounding diffusing element 3i of small extent (typically less than 110mm in length even less than 200mm in length) while preserving the homogeneity and efficiency. It is furthermore preferred not to interpose separating reflective walls between the support piece and the main reflector in the pattern area.

In an example 1A, one chooses as tape or double-sided adhesive tape (for sealing according to the IP44 standard) with a width of 10 mm: an acrylic (hardened) foam with two main faces carrying an acrylic adhesive, such as that the hyper joint H9012 (thickness 1.2 mm) or H9008 thickness 0.8mm, both sold by the company Nitto Denko, or alternatively: - a foam (hardened) polyvinyl chloride (PVC) with two main faces carrying an acrylic adhesive such as Scapa 5164 sold by the company Scapa, 0.8 mm thick, - a foam (hardened) polyester with two main faces carrying an adhesive, such as the S7080 sold by the company STOKVIS of thickness 0.8 mm. The seal for the abutments is a silicone with the choice white or transparent which joins it RUBSON HP. The dimensions of the parts and distances between parts are the following: - the surface of the glazing of facade 1 is 600x900mm and it is a glass of 4 mm thick, - the surface of the bottom glazing 1 'is 480x160mm and it is a 4mm thick glass, - the U-shaped sections 51 to 54 are 1mm thick, 480mm long, the width of the wings 51a is 20mm, the base 5 is 25mm wide - longitudinal edge side, the distance between the edge of the glazing 1 'and the glazing portion of the facade 1 is 45mm, - lateral edge side, the distance between the edge of the glazing 1' and the glazed portion of the facade 1 is 65mm, - the width of the zone mirror center is about 700mm, - the width of the peripheral mirror area between the inner edge and the edge is 70mm. - The height H of the internal space (between bottom reflector and facade glazing) is about 25mm.

To meet the IP 44 sealing standard, the glazing 100 is placed according to Example 1A in an oven, glazing 100 without fastening element (s) 8 to a wall type wall, elements described below. The oven test for sealing follows the protocol FCBAAMB-FIN 004 defined by the NF furniture, according to different cycles indicated in Table 1.

Oven cycle Temperature (° C) Moisture content (%) Duration (Week) 1 23 (+ 1- 2) 50 (+ 1- 5 stabilization) 1 2 23 85 2 3 23 30 2 4 40 30 1 23 ( + 1- 2) 50 (+ 1- 5 stabilization) 1 Table 1 The test is conclusive: the seal is confirmed and the fixation of the light box reliable. With the aforementioned alternative tapes, the test is also conclusive. In counter-example, if one uses the double-face adhesive H9004 of thickness 0,4mm, sold by the company Nitto Denko, one does not have waterproofing according to the standard IP 44. One avoids a double adhesive tape too thick, thicker than 3 mm and even 2mm.

By replacing the double-sided adhesive with a glue the seal is broken (and external), it is preferred that the mirror is not on the outer face of the bottom reflector so as not to risk tearing the adhesive 62 by sliding bottom reflector or excess weight forward. If a compression gasket is used on the bottom reflector side and the facade glazing side (against the wings of the profiles or of a monolithic frame), this overlaps too much over the diffusing pattern or on the bottom reflector and Other means of attachment must be provided, which complicates the product and the optical alignment. Alternatively, the main reflector is L and the base of the main reflector 52 is under the shaped edge (for example a beveled slice of the facade glazing) and the pattern 3 extends to or near this edge shaped. The main reflector 52 is then not carrying diodes even if the outer edge of the scattering pattern stops at the shaped edge, so there is no formation of low angle hot spots. The bottom reflector side flange is preferably not protruding under the pattern by more than 5mm. In a variant, the base of the lateral reflector 53 or 54 is under the shaped edge (beveled edge of the facade glazing) and the pattern 3 is extends to near or even to this shaped edge. The reflector 53 is then not carrying diodes even if the outer edge of the scattering pattern stops at the shaped edge, so there is no formation of low angle hot spots. The bottom reflector side flange is preferably not overflowing under the pattern of more than 5 mm. Alternatively, the flanges of the U-shaped profiles can be oriented opposite to the internal space and, if appropriate, the diodes can be placed on the base at the opposite of the wings because the rear face of the mirror reflects the rays received the most lateral. It is preferred to avoid for the entourage the use of one or more profiles in particular L less than 5mm thick and / or contact width with the facade glazing and with the bottom reflector less than 5mm or so Fixed by L-shaped brackets (square) as detailed later.

The illuminating mirror 100 is fixed to a wall (furniture, wall, ceiling, partition ...) using one or more profiles said fastening profiles 8, 81 to 84, here separated from one of the profiles 51 to 54 above the entourage. For mechanical reasons, it is preferred that the bottom reflector in the form of a (mineral) glass plate does not participate in fixing at the risk of loosening the adhesive sealing strips 62 and because the (mineral) glass is enough heavy. Still in Example 1A, four fastening profiles 81 to 84 forming a peripheral frame, abutting, are used near the edge of the facade glazing less than 15 mm. In fact, the bottom reflector is shifted inward with respect to the edge of the facade glazing. The fastening frame 8 is therefore glued in the area of the protruding rear face of the bottom reflector 1 '. We choose more precisely four U-shaped profiles 81 to 84 with a bottom and two returns directed towards the inside of the glazing, each: - in aluminum, - wide of 30mm, height (of the base) between the returns of 15mm, long of 890mm, thickness of the order of 1.5mm, returns spaced 5mm from the edge of the facade glazing, - the width of the double-sided adhesive tape 61 'on the fastening profiles, 20mm, - with an attachment opening 80 on a wing (rather than preferably a double-sided adhesive or glue). To evaluate the fixing of the illuminating mirror, the illuminating mirror 100 is fixed on a wall by hooks engaging in the fixing openings, a weight of 1 kg is placed on the mirror 100 and the test of the oven described in FIG. Table 1. It is found that the attachment is intact: no mirror support section is collapsed or even slipped. In contrast, if we replace the mounting profiles by one or more mounting plates placed on the plate bottom reflector on its outer face, it is found that the fixing is less reliable. Alternatively, the profiles 51 to 54 are spaced less than 1 mm without being joined by butt joint and the PCB and the diodes are watertight at least according to the IP44 standard. The double-sided adhesive on almost all the entourage maintains a robust and durable attachment. If a weight of 1 kg is placed on the mirror and the test of the oven described in Table 1 is repeated, it is found that the attachment is intact. The profiles 81 to 84 are masked by the mirror layer 2 and are devoid of return on the front face contrary to the prior art. The front face 12 of the facade glazing is devoid of masking element or fixing, or even walking or hollow macroscopic at least 1 pm and also surface texturing for the diffusion of light. This makes it easy to clean the front panel. Rather than a U-shaped section, a typically rectangular or hollow rectangular closed section can be employed. Still for example lA: - the PCB 40 carries 30 diodes, is 10mm wide, is flexible, with a thickness of about 1mm, - the PCB 40 + diodes 41 has an efficiency between 80 and 90 Im / VV - the distance ei between the diodes and the diffusing pattern 3 is of the order of 10 mm, the distance ef between the diodes and the bottom reflecting surface of the bottom reflector is of the order of 10 mm, the diodes , without optics, are of height of the order of 3mm, width less than 4mm, with a regular distance between diodes of 10mm ± 2mm. As shown in FIG. 1, which is a rear-side view of the illuminating mirror 100, the diffusing pattern 3 is elongated, composed of five spaced-apart diffusing elements 3i, in the form of rolls of the same or similar size, inscribed in a rectangular band R (in a line full). The width VV1 of the pattern 3, the band R is centimeter and less than 70mm. The diffusing pattern 3 is spaced from the slice 13 of the facade glazing.

The elongated pattern is defined by a first longitudinal edge 31, said internal, on the side of the central zone of the mirror, a second outer longitudinal edge 32, the most peripheral, along the lateral edge of the front glass 1, a first edge lateral 33 (top in the figure), a second opposite lateral edge 34. The dashed lines show the contours (the slice 13 ') of the bottom reflector 1' which is not shown to clarify the figure. The distance D1 between the inner edge 31 and the orthogonal projection on the plane of the diffusing pattern of the nearest emitting face on the first PCB is preferably at least 10 mm. The maximum distance Dmax between the inner edge 31 and the orthogonal projection on the plane of the diffusing pattern of the nearest emitting face is less than 50 mm and even less than or equal to 45 mm and better still 40 mm. The distance between the orthogonal projection on the plane of the diffusing pattern of the base 5a of the U-shaped support piece 51 and the inner longitudinal edge 31 is less than 25 mm better than 20 mm.

Preferably, the ends of the wings of the support piece are at the edge of the diffusing pattern and have a predetermined width to place the diodes at the distance D1 of at least 10 mm. It is preferred that the ends of the wings do not exceed under the diffusing elements of at most 5 mm because the bottom reflector by its layer 7 forms a better reflector.

The distance between the orthogonal projection on the plane of the diffusing pattern of the base of the main reflector 52 (devoid of PCBs, diodes) and the inner longitudinal edge is less than 10 mm. Preferably the ends of the wings of the main reflector 52 are at the edge of the diffusing pattern. It is preferred that the ends of the wings do not exceed under the diffusing elements of at most 5 mm because the bottom reflector by its layer 7 forms a better reflector. The distance between the orthogonal projection on the plane of the diffusing pattern of the base of a lateral piece 53 or 54 and the lateral edge is less than 10 mm. Preferably the ends of the wings of this part 53 or 54 are at the edge of the diffusing pattern. It is preferred that the ends of the wings do not exceed under the diffusing elements of at most 5 mm because the bottom reflector by its layer 7 forms a better reflector. The main reflector (like the side parts) could be oblique with respect to the facade glazing, as in the prior art, but this complicates the room, the way to guarantee the tightness or a small spacing and is more bulky and imposes a peripheral area of minimal mirror even larger. In example 1A: the width VV1 of the elongate pattern (therefore of the area R) is 40 mm, the length Li of the elongated pattern (hence of the area R) is 420 mm, the distance D 1 is 15 mm. A single row of diodes along the inner longitudinal edge 31 (or outer) suffices for the homogeneity of the illumination to normal as long as VV1 is less than or equal to 70 mm, but it is possible to add another row of diodes along the outer longitudinal edge, if we want to further increase the luminous efficiency. In this case, the main reflector carries this second row of diodes on its normal base to the facade glazing of at most 5 °. If it is desired to increase the efficiency by adding a row of diodes once the product has been designed, it is easy to break the seal between the sections by removing the bottom reflector for example by means of alcohol. It is the same for the replacement of the diodes (change of color, breakdown, change of power ...). A single row of diodes along the inner (or outer) longitudinal edge is not sufficient for homogeneity of illumination to normal if VV1 is greater than 70mm.

We must add another row of diodes symmetrically on the base of the main reflector profile 52, so here the outermost or even for simplicity surrounding the entire pattern. In this case, the main reflector carries this second row of diodes on its normal base to the facade glazing of at most 5 °. In an example 1B, the differences with example 1A are as follows: the width VV1 of the elongated pattern (hence of the area R) is 116 mm, the PCB 40, carries 90 diodes spaced apart with a regular distance 15mm, surrounding all the scattering pattern. As shown in FIG. 1a, the distance D2 between the external longitudinal edge and the orthogonal projection on the plane of the diffusing pattern of each emitting face of the second row of diodes 42 is then preferably at least 10 mm. The maximum distance Dmax the outer edge 32 and between the orthogonal projection on the plane of the diffusing pattern of the nearest emitting face is preferably less than or equal to 50 mm and even 45 mm and better still to 40 mm.

Diodes (on PCB) can also be placed on the lateral edges, carried for example by the lateral parts 53, 54 of the reflective surround. The distance D3 between the lateral edge and the orthogonal projection on the plane of the scattering pattern of the nearest emitting face is then preferably at least 10 mm. The maximum distance Dmax between the lateral edge 33 and the orthogonal projection on the plane of the diffusing pattern of the nearest emitting face and even the majority or each emitting face on the first PCB is preferably less than or equal to 50 mm and even 45 mm. The distance D4 between the opposite lateral edge and the orthogonal projection on the plane of the diffusing pattern of the nearest emitting face is then preferably at least 10 mm. The maximum distance Dmax between the lateral edge 34 and the orthogonal projection on the plane of the diffusing pattern of the nearest emitting face and even the majority or each emitting face of diodes of the first PCB is preferably less than or equal to 50 mm and even 45 mm and better at 40mm.

When the PCB 40 is flexible, completely surrounding the diffusing pattern 3 of a single PCB, with regularly distributed diodes, is simpler and faster than setting two groups of diodes on two PCBs along the inner and outer edges 31, 32 and connect them by one of the side edges 33, 34 for a common power supply.

The arrangement of the diodes along the edges depends on the design of the diffusing pattern. Whatever the diffusing pattern, it is preferred that the distance between each edge of the diffusing pattern and each nearest emitting face be greater than 10 mm and less than 50 mm and even 45 mm and better still 40 mm. The reflector surround and the diodes are positioned in the same way, preferably respecting D1 and, where appropriate, D2, D3, and D4, and the bottom reflector for a diffusing pattern forming a single rectangular band R, as shown in FIG. . In the band R of the scattering pattern there may be locally one or more mirror areas preserved, as shown by the dashed lines. FIG. 1c shows a pattern composed of a series of scattering elements 3i, round or oval, for example, of various sizes, inscribed in a rectangular zone R (or square if necessary) passing through the edges of the elements of the most attractive pattern. decentered. We then define: - D1 as the distance between the inner edge 31 of the scattering pattern 3 (thus also the inner longitudinal edge of the area R) and the nearest emitting face (always facing the inner edge), which distance is preferably at least 10 mm and at most 50 mm, and even 45 mm and better at 40 mm - D 2 as the distance between the outer edge 32 of the diffusing pattern (and therefore of the area R) and the emitting face closest to the row of diodes (always opposite the outer edge), preferably at least 10 mm and less than or equal to 50 mm and even 45 mm and better at 40 mm - D3 as the distance between the first lateral edge of the diffusing pattern (thus also of zone R) and the emitting face closest to the row of diodes (always facing the side edge), preferably at least 10 mm and less than or equal to 50 mm and even 45 mm and better still at 40 mm-D4 as the distance between the second lateral edge (thus also of the zone R) and the emitting face the p read near the row of diodes (always opposite the side edge), preferably at least 10mm and less than or equal to 50mm and even 45 mm and better at 40mm.

The entourage, the PCB or PCBs, the diodes are equidistant from the area R. Figure 1d shows a scattering pattern 3 'disk pattern inscribed in a square or rectangular area R (if oval, ellipsoid). In this configuration it is preferred to place the diodes all around the disk either by forming a rectangular frame or following the round outline if the PCBs and the entourage are fit (sufficiently flexible) to form a round. D is the distance between the edge 31 'of the round and each face is preferably at least 10 mm and less than or equal to 50 mm and even 45 mm and better at 40 mm. The figure shows a diffusing pattern forming a frame 3 "with a rectangular (or rounded-off) inner contour 31 "and a rectangular (or rounded) outer contour 32" In this configuration it is preferred to place the diodes all around the inner contour forming a preferably rectangular frame with a distance D1 ( constant) between the nearest emitting face and the inner contour preferably at least 10 mm and less than or equal to 50 mm and even 45 mm and better at 40 mm Figure 1f shows how to preferably position the diodes in the case of diffusing elements close enough but too wide in width to be surrounded by a single entourage.

It is arranged to define as many scattering patterns as necessary, elongated and each respectively inscribed in a rectangular area (or square) R, R1, R2 of width VV1, VV2, VV3 less than 230mm, better at 200mm, each zone R, R1, R2 being distant from the emitting faces - from the distance D1, D'1, D "1 of the longitudinal edge (preferably internal 31, 31 ', 31") of at least 10 mm and less than or equal to 50 mm, - the where appropriate, the distance D2, D'2, D "2 (if VV1 greater than 70mm) from the other longitudinal edge (preferably external 32, 32 ', 32") of at least 10mm and less than or equal to 50mm - and (for simplicity), where appropriate, distances D3, D'3, D3 and / or D4, D'4, D4 of the lateral edges (preferably 33 to 34 ") of at least 10 mm and less than or equal to 50mm The surrounds are not represented for the sake of clarity.A surrounding wall such as a U-shaped profile can serve as both a support piece of the diodes for two adjacent patterns. x adjacent patterns can be used a same profile of rectangular or square section. As shown in Figure 1 'which is a rear view of a mirror 10 "incorporating the frame pattern 3" the reflective surround 51b to 54b meanwhile is a rectangular frame all around the outer contour. In this frame pattern configuration the reflective surround forms with the bottom reflector (shown in dashed lines) and the facade glazing a dedicated waterproof case that does not include the support piece 51 and two mirror support profiles 81, 82 are used on the lateral edges of the glazing.

Again, if the width VV1 of the frame pattern is greater than 70 mm, all around the outer contour 32 'of the similar diodes 42 are also placed on the surround with a distance D2 between the nearest emitting face and the internal contour of preferably at least 10mm and less than or equal to 50mm and even 45mm and better at 40mm.

FIG. 2 schematically represents a partial cross-sectional view of a light-emitting diode illuminating mirror 200 in a second embodiment of the invention.

Only differences from the first mode are described. The illuminating mirror 200 differs in particular from the mirror 100 first by the width VV1 of the pattern, greater than 70mm. A single row of diodes 41 along the inner edge 31 (or outer) is not sufficient for the homogeneity of the illumination to normal. One may then wish to add another row of diodes 42 identical or similar to the first row, on the base of the main reflector section 52, thus along the outermost edge 32. It is recalled that the main reflector is preferably normal to the facade glazing for a better homogeneity. The main spokes F, F 'of the two groups 41, 42 are therefore at an angle of at most 5 ° with the facade glazing. Again, the distance D2 between the outer edge and the closest emitting face on the second PCB is preferably at least 10mm. The maximum distance Dmax between the outer edge and each emitting face on the second PCB is preferably less than or equal to 50 mm and even 45 mm and better to 40 mm.

The first PCB may be connected to the second PCB 40 'between the side edge of the diffusing pattern and the side piece of the surround. In fact, for simplicity, the first and second PCBs may be replaced by a single PCB and diodes all around the scattering pattern 3, the PCB being carried by the reflective surround 51 to 54.

The base glazing is this time, in a variant, coated with a specular reflection layer 7 ', preferably a mirror layer, such as a silver coating protected by its paint. In fact we can choose a background glass with mirror area identical to the front glazing (except here by their size). As a variant of attachment with respect to FIG. 1, as shown in FIG. 2a, the fastening frame 8, 81 to 84 is in the central zone of the mirror 200. Also the outer edge of the diffusing pattern 31 may be closer to the edge 13 of the facade glazing, typically less than 25 mm taking into account the distance D2 and the thickness of the profile of the entourage 52. The diffusing pattern 3 is here composed of five diffusing elements 3 complex shape (round and contiguous rectangles) or non-geometric variant inscribed in a rectangular area R as already explained which can be used to define D1, D2 and possibly D3 and D4 if necessary. FIG. 2 'schematically represents a rear-end view of a light-emitting diode illuminating mirror 200' in a variant of the second embodiment of the invention. Only the differences from the second mode are described. The illuminating mirror 200 'differs in particular from the mirror 200 by the first pattern forming a large L (hence six sides) on a lateral and longitudinal edge of the facade glazing 1 and by another pattern in small L (hence six sides) on the outside. Another longitudinal side edge of the facade glazing 1. Two L-shaped surrounds are used: - first surround with six U-shaped sections 51 to 56 here abutted by mastic 63 such as silicone, ie a profile for each side or edge of the large pattern diffusing, - second surround with six U-shaped profiles 51a to 56a here abutted by mastic 63 such as silicone, so again a profile by side or edge of the small scattering pattern. A single glazing 1 'is used, with the specular reflecting layer 7' (or diffuse 7), to form the two bottom reflectors of the small and large diffusing pattern, thus forming a frame, absent from the center of the mirror, for wall mounting. , (inner and outer contour 13 'of the potted glass 1). This glazing 1 'of mineral glass may alternatively be a plastic made of PMMA or polycarbonate. We can also use for each entourage a L-shaped glazing, so the shape of each scattering pattern.

Alternatively, the profiles 51 to 56 are spaced less than 1 mm are joined by abutment and the PCB or diodes and are waterproof. The double-sided adhesive on almost all the surrounding provides a satisfactory first level of sealing and maintains a robust and durable attachment.

FIG. 3 schematically represents a partial view in longitudinal section of a light-emitting diode-illumination mirror 300 in a third embodiment of the invention. Only differences from the first mode are described. The illuminating mirror 300 differs in particular from the mirror 100 by the size of the bottom reflector 1 'which extends in the central zone and the zone of the second diffusing pattern (not shown). In other words, only one bottom reflector is used for the two scattering patterns. In addition, the four U-shaped profiles forming the reflective surround of the first diffusing pattern are replaced by profiles 51 'to 54' as spacers, of rectangular or square closed section. For greater efficiency, the sidewall 5 'internal space side of the main reflector 52' is at the border with the outer edge 32 of the diffusing pattern or less than 10mm. Alternatively, the sections 51 'to 54' are spaced less than 1mm are joined by abutment and the PCB or diodes and the diodes are watertight. The double-sided adhesive on almost all the surrounding provides a satisfactory first level of sealing and maintains a robust and durable attachment. As shown in FIG. 3a, each diffusing pattern 3 is formed of two diffusing elements 3i in a band inscribed in a rectangular zone R. In addition, the watertight case is a case common to each diffusing pattern, instead of use a dedicated case by diffusing pattern, and also protects the power wire 91 and the transformer 93 which no longer need to be sealed. To do this, the lateral sections 53 'and 54' are enlarged. The diode support parts 51 'and 51'a more central than the main reflectors 52 are not part of the waterproof housing. The support parts 51 'and 51'a are not necessarily joined to the common box.

It is of course possible to use a U-shaped profile (or H or Z or even L) for the diode support piece 51 'or 51'a. In a variant, the bottom reflector is coated on the internal face of the diffuse reflective layer already described in FIG. 7. It may then be a large metal plate coated with this diffusing layer or even a metal plate. brute. Figure 4a schematically shows a rear view of a light-emitting diode illuminator mirror 400 in a fourth embodiment of the invention. FIG. 4 is a partial side sectional view from a longitudinal edge 131 of the facade glazing 1. The diffusing pattern 3 inscribed in a rectangular zone R is in the form of six bubbles (including a cut-off bubble) and the lateral edge 34 of which extends to the shaped edge Z of the wide edge 34 of at most 2 mm. In order to illuminate the diffusing pattern 3 in all its extent, a non-return profile is placed against the rear face 11, which is a square 54 ", L, metallic (or reflective) joint joined to the rear face by a so-called joint edge which is a silicone sealant 610 white or preferably transparent in the edge Z. The single return 54b, bottom reflector side 1 ', extending opposite the diffusing pattern 3 and still fixed by the double-sided adhesive face 62. The bracket is of ep thickness of 0.8 mm or 1 mm.It is preferred that the bracket 54 "is devoid of diodes (source of hot spots).

In a variant, a plastic box (preferably with a reflective layer on the rear face) or even an aluminum, U-shaped, with a thickness of at most 0.8 mm or even 1 mm is used for the entourage, optionally with hanging profiles for the support member 51 and main reflector 52 sections for a contact width of at least 5mm on the rear face 11 with the double-sided adhesive 61. One can achieve the same system of square and edge seal under an edge shaped from the other side edge (in addition) preferably angle devoid of diodes and even realize the same system of square and edge joint on a longitudinal edge and preferably the main reflector is not carrying diodes. The fixing by the double-sided adhesive 61 on three sides of the rear face or even on two sides is sufficient. Alternatively one can realize a plastic box with reflective layer (outer or inner side) or metal box with fasteners returns or hanging profiles except in the shaped edge or edges with edge joints as described. Figure 5a schematically shows a rear and partial view of a light emitting diode illuminator mirror 500 in a fifth embodiment of the invention. Figure 5 is a partial longitudinal sectional view of the mirror 500.

In this configuration, the dedicated waterproof case further comprises three U-shaped profiles glued by the double-sided adhesive 61 to the rear face of the facade glazing 1 and under the mirror layer 2 and by the double-sided adhesive 62 to the reflector of bottom 1 '. A fourth section 8, straight, in U with a base 8a and two returns 8b opposite the internal space 14 (or in a rectangular or square closed section, spacer type), made of metal (alternatively plastic or in glass and with a reflective layer). This fourth section has a contact width of the adhesive 61 'of at least 10 mm for good attachment of the mirror and a material thickness of at least 1.5 mm and possibly a height H' greater than H. This profile 8 serves not only for attachment to a wall (furniture, wall ...) via one or two mounting openings 80 but also for the entourage, as support part of the diodes on the face 8'a. This fastening profile thus carries via this right wall 8'a the first PCB 40 with the diodes 41 along the longitudinal inner edge 31 of the scattering pattern 3, for example three bubbles with a width of at most 60mm and at a distance D1 of At least 10 mm of the inner edge 31. The surface of this fastening section opposite the edge 13 'of the reflector 1' is sealed by adding a "lateral" sealing element such as a silicone sealant seal 64 '. The profile is abutted with the profiles 53 'and 54' by sealant 63 silicone. Alternatively rather than cumulatively, the longitudinal outer section (main reflector) can be replaced by a mirror support section in the same configuration. This is also possible if it is a common box including surrounding also a second scattering pattern.

Figure 5'a schematically shows a rear and partial view of a light emitting diode mirror 500 'in a variant of the fifth embodiment of the invention. This mirror 500 'differs from the mirror 500 in that the fastening profile 8 replaces not a support part of the first PCB but a profile, forming part, as preferably longitudinal wall to the inner edge (or external variant) of the housing common sealing of the first PCB 40 and the power supply. Here the diode support section 51 'for example a spacer of square or rectangular section is not necessarily abutted or fixed by adhesive or joined to the other lateral sections 53', 54 '.

Figure 5 "schematically shows a rear view of a 500-light-emitting diode illuminating mirror in a new embodiment of the invention. It differs from the mirror 500 in that each scattering pattern 3 (strip with central return, forming a "T" therefore with eight sides or edges) is surrounded by a PCB on seven profiles (type spacers of rectangular or square lateral section, butt jointed 64) and on one of the mirror support profiles 81 or 82 forming part of the fastening profile 8 (four-piece frame 81 to 84 in the central mirror area). Each of the profiles is part of the surrounding of a diffusing pattern and carries the diodes for its pattern diffusing on a portion 810, 820 of the profile.

Figure 6a schematically shows a rear and partial view of a light emitting diode illuminator mirror 600 in a sixth embodiment of the invention. Figure 6 is a partial view and longitudinal section of the mirror. In this configuration, the dedicated waterproof case further comprises three U-shaped profiles glued by the double-sided adhesive 61 to the rear face of the facade glazing 1 and under the mirror layer 2 and by the double-sided adhesive 62 to the reflector of bottom 1 '. A fourth section 8 straight, is U with a base 8a and two returns 8b opposite the inner space 14 (or in the form of a rectangular or square section closed section, spacer type) is between the bottom reflector and the facade glazing but of different dimensions. This profile is made of metal or plastic or reflective layer glass. It has a material thickness of at least 1.5 mm, a width of contact with the mirror layer by the double-sided adhesive 61 'of at least 10 mm and a width of contact with the bottom reflector by the adhesive double-sided 62 'of at least 10mm. This profile 8 carries, via a straight wall 8'a of the base, the first PCB with the diodes 41 along the longitudinal inner edge 31 of the diffusing pattern 3, for example three rollers 3i with a width of at most 65 mm and at a distance D1 at least 12 mm from the inner edge 31 of the diffusing pattern. This profile 8 serves not only for the entourage and the waterproof housing but also for fixing to a wall (furniture, wall ...). Also this fastening section 8 comprises two protruding ends 8c, 8d (here longitudinal) of the bottom reflector 1, on two opposite edges ends still under the mirror layer 2 at the periphery of the facade glazing 1 and with means for fixing such that an opening 80 or a double-sided adhesive.

Alternatively rather than cumulatively, the longitudinal outer section (main reflector) can be replaced by a mirror support section in the same configuration. This is also possible if it is a common box including surrounding also a second scattering pattern.

Figure 6'a schematically shows a rear and partial view of a light emitting diode mirror 600 'in a variant of the sixth embodiment of the invention. This mirror 600 'differs from the mirror 600 in that the fastening profile 8 replaces not a support part of the first PCB but a profile, forming part, preferably as a wall along the inner edge (or the outer edge alternatively ), the common sealing box of the first PCB 40 and the power supply 93. Here the diode support profile 51 'for example of rectangular section, is not necessarily abutted or attached by adhesive or joined to others lateral sections 52 ', 53', 54 ', for example of rectangular section.

FIG. 7 schematically represents a partial view in longitudinal section of a light-emitting diode illuminating mirror 700 in a seventh embodiment of the invention.

Only differences from the first mode are described. The illuminating mirror 700 differs in particular from the mirror 100 by the choice of the bottom reflector 1 "which is a metal plate (aluminum sheet for example of thickness 0.8 mm), for example coated on the face facade glazing side of a diffuse reflection layer 7 or alternatively polished or still raw and in that the main reflector 52 'is a profile (spacer and between the mirror layer 2 and the bottom reflector 1 ") of rectangular section along the outer longitudinal edge 32. FIG. 8 schematically represents a longitudinal sectional view of a light-emitting diode illuminating mirror 800 in an eighth embodiment of the invention. Only differences from the first mode are described. The illuminating mirror 800 differs from the mirror 100 by the choice of the dedicated housing. A metal casing 50 is used whose bottom, plane (or concave towards the internal space) forms the bottom reflector 1 "and four side walls or flanks 501, 502, 503, 504, normal to the facade glazing, are part of the casing does not have a simple U-shaped section but also has a return 50a oriented in the internal space 14 and with the double-sided adhesive 61 on its periphery (see Figure 8a which is a top view of the box 50 alone), forming a sealing frame, the return is perpendicular to the side walls or flanks 501 to 504, and surrounds the diffusing pattern without overflowing on the diffusing pattern 3. FIG. 8a shows a schematic view from above of the dedicated box with the frame return 50a, the four walls 501 to 503, the double-sided adhesive forming a sealing frame 61. For fixing the contact width via the double-sided adhesive 61 with the facade glazing 1 all around the return frame, under the c mirror, is at least 5mm preferably. The thickness of the box is less than 5mm, for example 0.8mm. Such a piece can be made by double folding. If it is preferred to fold the sheet to form a plurality of returns (not shown) for example four returns, the latter are joined by silicone sealant between the four areas (strips) of double-sided adhesive. As a variant of fixing: the frame return is outside the internal space but the compactness is lost and the scattering pattern is removed from the edge of the facade glazing; returns are external or at least one return is outside (for example back of the innermost longitudinal wall 501) and extends laterally beyond the case on the center side of the mirror, for example in a U-shaped section with an opening, to form a wall-wall attachment area (fixed to the glazing of facade preferably by double-sided adhesive) related to the area of the diffusing pattern. As a variant of the box, the material of the wall 1 "is plastic, such as polycarbonate or PMMA, with a reflective layer, preferably opposite the internal space The thickness of the box is less than 5 mm, for example 3 mm It is possible to use the mirror support profiles as already described on either side of the box or on the outer face of the bottom reflector FIG. 9 schematically represents a partial view of a longitudinal section of a light-emitting diode-illumination mirror 900 in a ninth embodiment of the invention.

Only differences from the eighth mode are described. The illuminating mirror 900 differs from the mirror 800 firstly by the shape of the box and by its attachment. A box of simple section in U (bottom wall forming the base and sidewalls format the wings) of thickness of about 1 mm is used. The bottom is planar (or alternatively concave towards the internal space) forming the bottom reflector 1 ", possibly with a white reflector-type layer on the internal space side.For its fixing, two fastening profiles 511, 512 are used, which are L-shaped brackets each with: - a first part against a side wall 501, 502 along a longitudinal edge 31, 32 of the diffusing pattern and internal space side 14, - a second part at 90 ° against the mirror layer 2 always in the internal space and without exceeding the edges 31, 32. The fixing is done by screw 6.e Place two diode strips 41, 42 bonded by double-sided adhesive 6 on the attachment profiles along the edges 31 , 32.

If this screw goes through 6e entourage, it is preferred to place a sealing washer (elastomer, rubber) between the screw and the wall. The screw (and / or other screws or nuts) may also be used to secure the PCB to the bracket. The box 50 is for example fixed to a wall, a furniture wall, via fastening plates 8 'with housing type fastening handles, metal plates bonded for example via the same double-sided adhesive 6' rather than by drilling by screws (to prevent breakage of leakage according to 1P44). As shown in FIG. 9a, which is a top view of the box with the attachment profiles and the double-sided adhesive, the box is fixed by the double-sided adhesive 61 all around the diffusing pattern 3, forming thus a sealing frame, for simplicity double-sided adhesive prefixed on the mirror layer 2. For sealing this adhesive being in contact not only with the brackets but also on the entire edge of the box (and exceeds beyond the surrounding, outside) including adhesive capable of compensating for any defects in flatness of the wafer to avoid a water diffusion path for example between the inner wall of the sidewall and the back of the square. The adhesive is of sufficient width for good mechanical fixing, so preferably at least 5 mm with each bracket 511, 512. Its total width is preferably at least 10 mm. As an alternative fastener shown in FIG. 9b, four brackets 511 to 514 with butts are used. As a variant of sealing and fixing, shown in FIG. 9c, only two longitudinal (or alternatively lateral) strips of double-sided adhesive 61 are placed under the edge of the box (opposite longitudinal walls 501, 502) and two brackets and protruding outside the box, and the sealing is completed by connecting them externally by an additional seal which is a putty 64 like silicone, white or transparent, additional seal against the side walls 503, 504. Alternatively of box, it is plastic, such as polycarbonate or PMMA with a reflective layer preferably opposite the internal space. The thickness of the box is less than 5mm, for example 3mm.

FIG. 9 'schematically represents a partial view of a longitudinal section of a light-emitting diode illuminating mirror 900' in a variant of the ninth embodiment of the invention.

Only the differences from the ninth mode are described. The illuminating mirror 900 'differs from the mirror 900 firstly by its external attachment to the internal space by the brackets 511, 512. As shown in FIG. 9'a, the seal is preserved by two double-sided adhesive strips 61 on the portion of two longitudinal walls 501, 502 and an additional seal external to the box which is a peripheral sealant 64 such as silicone against the side walls 503, 504. Alternatively shown in Figure 9'b four brackets are used for fixing by four walls of the box. The double-sided adhesive 61 forms a sealing frame and for simplicity and is prefixed all around the diffusing pattern 3. The fastening brackets and the slices of the walls 501 to 504 are in contact with the double-sided adhesive which also overflows outside the box for example of at most 5mm or 2mm. FIG. 9 "schematically represents a longitudinal sectional view of a light-emitting diode-reflecting mirror 900" in another variant of the ninth embodiment of the invention. Only the differences from the ninth mode are described. The illuminating mirror 900 "differs from the mirror 900 by its extent over almost the entire surface of the facade glazing 1 forming a common box for the power supply or even for other diffusing patterns (not shown) Naturally the support part 51 ' Here, a section of rectangular section completes the reflective surround and is protected by the common case Optical measurements are made on illuminating mirrors with four architectures of reflectors to evaluate the efficiency.

In the four examples Ex1 to Ex4, the illuminating mirror comprises a facade glazing with a mirror layer, a scattering pattern, diodes on a PCB and a dedicated box, as described for Example 1B. More precisely, in the four examples, the diodes are the product called 5MD3528 from ILLUSION LED Limited. The PCB with the diodes has an efficiency of 80 lm / w. The RL is, like the TL, defined in the EN410 standard. The measurements were carried out under illuminant D65 with a Konica Minolta CM-3700d spectrophotometer. In the four examples, the façade glazing is a 4 mm Planilux glazing of the plaintiff company covered on its back side with a layer of silver of at least 50 nm with a protective paint. The silvering and its protection were sandblasted to form the diffusing pattern giving a blur of 95% and a TL of about 70%. This is the product Miralite REVOLUTION, sandblasted, the plaintiff company. In Example Ex1, the glazing of the bottom reflector is provided with a diffuse reflective layer which is on its outer main face and therefore opposite to the internal space. Specifically, it is the white Planilaque product of the plaintiff company composed of a 4mm Planilux glazing and a white lacquer. In Example Ex2, the bottom reflector glazing is provided with a specular reflecting layer which is on the outer face and therefore opposite to the internal space. Specifically, it is the product Miralite REVOLUTION, the plaintiff company composed of a 4mm Planilux glazing covered on its outer surface with a silver layer of at least 50nm, with a protective paint. In Example Ex3, the glazing of the bottom reflector is provided with a diffuse reflective layer which is on the inner face and thus on the internal space side. More precisely, it is the product Planilaque white composed of a Planilux glazing of 4mm and a white lacquer. In Example Ex4, the bottom reflector is an aluminum plate covered with a diffusing white paint. Table 2 below shows the optical measurements of case comparison using the four aforementioned bottom reflectors. Ex1 Ex2 Ex3 Ex4 RL (%) 55 92 80-85 85-97 TL (c) / 0) 2.3 0 2 - Flux (lm) 40 46 45 42 Efficiency (Im / VV) 12 14 13 12 Table 2 The flow measurement protocol and efficiency is as follows, for each example. The mirror is first fixed in the center of an integrating sphere to measure the luminous flux. From the measured luminous flux, it is then possible to calculate the luminous efficiency of the mirror.

The RL value of Example 1 measured is not significant because it does not take into account the light propagating on the wafer. The light transmission TL measured on the outside of the internal space is low enough not to lose light.

The flow is satisfactory for all the examples. The internal space-side surface of the glass plate may be smooth as here or alternatively textured or with a diffusing layer.
