ι + LIGHTING MIRROR WITH LIGHT EMITTING DIODES

The present invention relates to lighting mirrors and more particularly to a lighting mirror with light emitting diodes.

Light-emitting diodes or LEDs (LEDs in English) were originally used to constitute indicator lamps or indicator lights for electrical and electronic devices, and have already been used for several years to light signaling devices such as traffic lights. signaling, motor vehicle lights (turn signals, position lights), or portable or beacon lamps.

The interest of the diodes is their long lifespan, their lighting efficiency, their robustness, making the devices using them more durable, and requiring reduced maintenance.

Recently their use has grown in the field of mirrors in order to offer illuminating mirrors.

We know from patent application WO2015 / 004363, in the embodiment presented in FIG. 3, an LED illuminating mirror which comprises:

- facade glazing with a first main face forming the rear face, and a second main face forming the front face,

- a central area forming a mirror,

- a diffusing strip on the rear face of the facade glazing obtained here by sanding or acidifying the glass, peripheral to the mirror,

- a group of inorganic light-emitting diodes (or LEDs) arranged on the side of the rear face, along the diffusing strip.

- a rear glazing, smaller in size than the front glazing, carrying a layer reflecting the rays emitted by the diodes in the internal space between the two glazing.

This illuminating mirror is fixed to a wall wall via peripheral fixing means at the rear of the facade glazing.

The object of the invention is to provide an alternative lighting mirror which can be used more in applications in which the rear face of the lighting mirror is accessible without making the design of the mirror more complex.

To this end, the present invention firstly provides an illuminating mirror which comprises:

- a first glazing, forming facade glazing, preferably mineral glass in particular tempered glass (preferably clear or extra-clear glass, rather than bronze, gray, green) or organic, with a first main face called face F1, and a second face main face called F2 and a first edge called edge CT1, preferably of thickness E1 at most 4.5 mm, and even at most 3.5 mm and better at least 2 or 2.5 mm preferably rectangular or square shape (CT1 edge then including two longitudinal sections and two lateral sections),

- a reflective metal layer on the face F2, called the mirror layer, giving the mirror functionality on the face F1, in particular present in a central area of the first glazing and even occupying at least 50% and even at least 70% or at least 80% of the face F2, preferably with a thickness Ec of at most 0.5 μm, in particular a silver-based mirror layer and even preferably a silver-based deposit, in particular by silvering, the first glazing and mirror layer assembly present a light reflection R _L preferably greater than or equal to 85%, 88% and even 90%, measured on the face F1 side

- (to have at least one light area on the side F1 face in the on state) the face F2 locally has a surface roughness thus forming a contiguous diffusing textured area surrounded by the mirror layer, diffusing textured area of width W1 of at least minus 10mm and even 20m, and at most 100m and better at most 80 or 60mm and of length L1> W1, opposite this diffusing zone and side F1 face, the first glazing having in the diffusing textured zone a blur at least 80% and even at least 85 or 90% on the side F4, a light transmission T _L greater than 50% and even 70% and in particular at most 85 or 80%,

- a second glazing, preferably mineral glass in particular tempered glass preferably clear or extra-clear glass, rather than bronze, gray, green) or organic with a main face called face F3, and a main face called face F4 and a second edge said edge CT2, preferably of thickness E2 of at most 4.5mm, and even of at most 3.5mm and better of at least 2 or 2.5mm, in particular of size and shape (and even of thickness ) identical to facade glazing, preferably rectangular or square (edge CT2 then including two longitudinal sections and two lateral sections), preferably first and second glazing are made of mineral glass

- between the first and second glazing, a group of inorganic light-emitting diodes, in a row on a support for electrical tracks called PCB (PCB in particular parallelepipedic, preferably of thickness at most 3mm, in one or more pieces aligned or even abutted on along the textured area T3), the PCB being on a metal profile in particular of U or L section forming in particular a heat sink, the group diodes (with emission from the front or from the side) each having one emitting face of light forming an angle between 85 ° and 95 ° with the face F2 and even between 88 ° and 92 °.

In addition, the faces F2 and F3 are facing each other, and the first and second glazing are spaced and associated at the periphery of the faces F2 and F3 by means of sealing with liquid water, masked (side face F1) by the layer mirror and masked (face side F4) by a masking layer on face F3 -which may be another mirror layer or an opaque layer possibly diffusing possibly on another mirror layer-. Preferably the edges CT 1 and CT2 (in particular polished, planes), are visible and the water-tightness means are flush with the edges CT 1 and CT2 or set back at most 1 mm, sealing means at liquid water at least 10mm wide and better at most 40mm or 30mm,

The total thickness E _T between the faces F1 and F4 is at most 13mm and even at most 10mm.

Furthermore, the second glazing comprises at least a first through hole from the face F3 to the face F4 for the power supply, first through hole which is more central than the peripheral liquid water sealing means, first through hole suitable for accommodating, and preferably housing, a first insert (preferably metallic) coming out on face F4 and attached to an electrical supply box on the side of face F4 (autonomous case or adapter to the mains).

Finally, the diode group, the PCB, the metal profile (and the first insert) are spaced from the liquid water sealing means, the diode group, the PCB and the metal profile (and even the internal connections) being between the mirror layer and the masking layer.

Thus, the invention provides an illuminating mirror which is compact, protected in particular from projections (water, in a room such as the bathroom, etc.) and the rear of which presents no danger.

In particular, the first through hole with the first insert mounted on the second glazing makes it cleverly and discreetly possible to supply electricity. In particular, this first insert may be an element forming part of the connectors and / or a fixing element for the lighting mirror (hinge, fixing hook, etc.).

The illuminating mirror does not need a particularly metallic frame, the edges CT1 and CT2 (planes, aligned, polished, etc.) of the first and second glazing are thus visible. The internal connections and the diodes are masked by the glazing made opaque outside the light area.

In addition, the illuminating mirror retains design flexibility for the shape and extent and location of the diffusing textured area. The diffusing textured area prevents glare. The diffusing textured zone is arranged on the face F2, to be protected and the front face F1 in contact with the external environment can be smooth and easily cleanable.

The metal profile forms a heat sink for the diodes, there is also no risk of burns.

We may wish for decorative or functional lighting, in particular at least 100 lux at 1m on the F1 side.

Preferably the intensity of the electric current in the power supply circuit of the first group of diodes (and of any other group of diodes if necessary) is less than 0.5 mA.

The first through hole may preferably be round (or equivalent: oval, etc.) with a width of at least 15mm, preferably of at least 20mm and even of at least 25mm and preferably of at most 50mm and even 35mm.

The first insert, notably hollow, for example made of plastic, and used to hide an electrical wiring (for example electrically insulated from the insert if metallic) going to the power supply box.

The first insert may however advantageously be metallic (aluminum, stainless steel, etc.) and form part of the external electrical supply connection.

The second glazing may include a second through hole, preferably identical to the first - preferably spaced from the first through hole in particular at least 10 cm between the edges of the holes -, with a second insert, preferably identical to the first, and even as much through hole with insert as necessary preferably identical to the first through hole with first insert.

Local through holes are preferred rather than a single elongated through hole forming a groove with an elongated insert (adapted accordingly), for example, for fixing to a wall (partition, etc.).

One or more through holes with inserts (for example hinges) can be used for fixing the lighting mirror without being used for power supply.

In a first embodiment, the group of diodes is supplied electrically at a DC voltage of at most 30V, for example at 12V, and on the face side

F3;

a first end of a first internal connector (in the internal space), in particular a first given terminal (for example negative) is in electrical contact with the first metal insert,

- and preferably with a first end of a second internal connector (in the internal space) - in particular of a second given terminal (for example positive) - is in electrical contact with a second, metallic insert, housed in a second through hole, from face F3 to face F4, spaced from the first through hole, second insert coming out from face F4 and attached to said electrical supply box on the side of face F4 (fixed on face F4 or associated with a cheek of a piece of furniture when the lighting mirror is a door of this piece of furniture).

The electrical contact between the first internal connection and the first metal insert preferably on a particularly projecting area of the first insert on the side F3 side (and even between the second internal connection and the second metal insert) comprises, as desired: a solder, a conductive bonding or a mechanical contact (screwing; clipping, plugging in, etc.).

In a preferred configuration of this first embodiment:

- the first insert is a first metal hinge and the second insert is a second metal hinge

- or the first insert is a first wall fixing element (of the mirror) and the optional second insert is a second wall fixing element (of the mirror).

The internal connections advantageously include:

- a first internal connection comprising a first wiring between the PCB and the first through hole (in particular a first metallic foil, for example for the positive terminal, for example made of copper and better bonded to the face F3)

- a second internal connection comprising a second wiring between the PCB and the second through hole (in particular a second metallic foil, for example for the negative terminal, for example made of copper and better bonded to the face F3)

The first and second metallic foils may be in electrical contact (soldering, conductive bonding) in one or more separate areas of connection of the PCB or may each be connected to an electrical wire at the outlet of the PCB, for example of short length (for example from 2 to 10 cm).

The first and / or second metallic foil, for example copper, is for example at most 2 cm wide and even 1 cm or even at most 5 mm.

As many foils are used as necessary.

If another group of diodes is used (opposite edge of the diffusing textured area), a third internal connection can be in electrical contact with the first insert (like the first internal connection), in particular the metal hinge, and a fourth internal connection can be in electrical contact with the second insert (like the first internal connection), in particular the metal hinge.

If the face F2 has another diffusing textured zone associated with a group of additional inorganic light-emitting diodes (to form an additional light zone) an internal connection can be in electrical contact with the first insert (like the first internal connection), in particular the hinge metal, and an internal connection can be in electrical contact with the second insert (like the first internal connection), in particular the metal hinge.

There can be as many through holes and preferably metallic inserts as desired (for example third metal hinge and even fourth metal hinge) for independent control of several light zones on the face F1 side, for example for piloting first and second zones luminous, in particular forming peripheral peripheral bands along opposite edges of the mirror, continuous bands or formed by a set of patterns.

Preferably, the peripheral means for sealing with liquid water - in the form of a frame - comprise:

- an adhesive polymeric strip, in particular adhesive foam (forming a spacer), for example acrylate or polyurethane foam; preferably opaque foam to hide the internal space

- or a metallic spacer (steel, aluminum, etc.), made of one or more metal parts at least abutted, spacer comprising:

- a first longitudinal part with a longitudinal face bonded to the face F2 (in particular on the mirror layer or its protective layer),

a second longitudinal part with a longitudinal face bonded to the face F3 (in particular on the masking layer, in particular on a mirror layer or its protective layer),

- a side part with an apparent side face flush with the edges CT 1 and CT2 or set back no more than 2 or 1mm, optionally another side part on the internal space side.

The spacer is preferably as light as possible, for example it is hollow, in particular of rectangular or square section, or is open towards the internal space, in particular of C section. The thickness of this hollow or open part is preferably at most 1mm or even at most 0.5mm for the longitudinal parts and / or for the visible side part (and even the other side part).

The visible side face can be brushed, polished and / or include a decorative finishing layer, which is a deposit (paint, etc.) or an attached strip glued to the metal side part (wood look, etc.).

Preferably, for bonding the longitudinal faces, a double-sided adhesive, for example at most 0.5 mm thick and even at most 0.3 mm, is chosen.

Preferably the internal space is at most 6mm and even at most 4.5mm and better at least 2 or 3mm, especially if an internal light guide is incorporated.

To improve light extraction advantageously, in a preferred embodiment the illuminating mirror comprises a glazing called internal glazing, transparent, in mineral or organic glass, between the faces F2 and F3, with a main face called F5, and a face so-called main F6 and a first so-called T3 wafer, the internal glazing being in the internal space delimited by the sealing means with liquid water, internal glazing of thickness Eg at most 4.5 mm or better at least plus 3.5mm and greater than the height of the emitting faces, for example at least 2mm or 2.5mm.

Each light emitting face is opposite the slice T3, the internal glazing being thus optically coupled with said group of diodes, the distance between the slice T3 and each emitting face of the diode group is less than or equal to 5 mm and better than 2 or 1mm and preferably not zero.

Preferably, the internal glazing is of rectangular shape. Preferably the section T3 is a longitudinal section.

The internal glazing includes:

a central region facing the textured diffusing zone, of width W'1 at least equal to W1, comprising means for extracting the light via the face F5 and / or the face F6, which are means for diffusing surface of face F5 and / or face F6 or volume diffusion means in the internal glazing, for example a central region in the form of a rectangular strip

- a peripheral region on the side of the slice T3 and contiguous to the central region, peripheral region opposite the mirror layer (and the masking layer) over a width D -between the edge of the central region and the slice T3- at least 5mm and at most 20mm and preferably 8 to 12mm

- preferably (if another group of diodes associated) another peripheral region contiguous to the central region, peripheral region opposite said peripheral region opposite the mirror layer (and the masking layer) over a width D ′ -between the edge of the central region and a slice T'3 of the internal glazing opposite to T3- of at least 5mm and at most 20mm and preferably from 8 to 12mm.

In addition, the thickness of the internal glazing is preferably greater than the width of the emitting face of the diodes. Preferably the internal space is at least 2mm thick (high), especially if the internal glass is incorporated into the internal space.

The internal glazing thus extends between the mirror layer and the masking layer to avoid hot spots due to diodes too close to the edge of the diffusing textured area.

In the absence of internal glazing, it can also be ensured that the diodes are at least 10mm from the edge of the diffusing textured area and preferably 15-25mm.

The internal glazing is a monolithic glass rather than a laminated glass for example with a diffusing laminating interlayer.

The internal glazing can be a plastic diffusing for example a PMMA Evonik SM for example of thickness 4mm.

Preferably, the light extraction means are chosen from:

- a diffusing texturing of the face F5 or F6 of the internal glazing, in particular in mineral glass, for example a sandblasted glass

- a diffusing layer, in particular with diffuse reflection on the face F6 of the internal glazing made of mineral glass, for example a white paint (allowing light to pass through on the face side F3 or not)

For example, the diffusing textured zone can be a diffusing strip (solid) or comprises diffusing patterns (cloud, star, geometric pattern, etc.) spaced at least 5 cm apart (inscribed in a strip) along a section of the glazing. and T3 is a longitudinal section along the diffusing strip or the area covering the diffusing patterns.

In one embodiment of the invention, the illuminating mirror comprises:

- between the first and second glazings along an edge of the diffusing textured zone opposite the edge of the textured zone of said group of diodes, another group of inorganic light-emitting diodes, in row on another support for electrical tracks called another PCB (PCB in particular parallelepiped in one or more aligned or even abutting parts), the other PCB being on another metal profile in particular of U or L section forming in particular heat sink, the diodes of said other group (with emission from the front or by the side) each having a light emitting face forming an angle between 85 ° and 95 ° with the face F2 and even between 88 ° and 92 °.

The other group of diodes, the other PCB, the other profile are spaced from the liquid water sealing means, the other group of diodes, the other PCB and the other profile being between the mirror layer. and the masking layer.

Preferably for W1 of at least 60mm, another group of diodes is used for a uniformity of light.

Preferably for W1 of at least 80mm with internal glazing having a diffusing textured face, the other group of diodes is used.

To further improve light extraction, the illuminating mirror preferably includes:

a first reflecting or diffusing zone, between the masking layer and said peripheral region of the internal glazing, of thickness preferably at least ίο plus 0.4mm and even at most 0.2mm or 0.1mm, along the edge of the textured diffusing area on the first group of diodes (and edge T3), of width DL -from the edge of the textured diffusing area on the first group of diodes-, D1 being at least 5mm and at most 20mm and preferably from 8 to 12mm, a second reflecting or diffusing zone, between the mirror layer and said peripheral region of the internal glazing, preferably of thickness at most 0.4mm and even at most 0.2mm or 0, 1mm, along the edge of the diffusing textured area on the first group of diodes (side edge T3), of width D2 'from the edge of the diffusing textured area edge side T3 of at least 5mm and at most 20mm and preferably 8 to 12mm possibly (if other group of diodes) a third reflecting or diffusing zone, between the masking layer and an opposite peripheral region of the internal glazing, in particular of thickness of at most 0.4mm and even at most 0.2mm or 0.1mm, along from the edge of the textured diffusing area on the side opposite to the edge T3, of width D3 · from the edge of the textured diffusing area opposite the edge T3, D3 "being at least 5mm and at most 20mm and preferably from 8 to 12mm possibly (if another group of diodes) a fourth reflecting or diffusing zone, between the mirror layer and an opposite peripheral region of the internal glazing, in particular of thickness at most 0.4mm and even at most 0.2mm or 0.1mm, along the edge of the textured diffusing area opposite the edge T3, of width D4 · -from the edge of the textured diffusing area opposite the edge T3-, D4 being of at least 5mm and at most 20mm and preferably 8 12mm.

In this latter embodiment preferably:

- a diffuse reflection layer, in particular a white paint on the masking layer or a texturing of the peripheral zone opposite F5 forms the first diffusing zone

- And / or a diffuse reflection layer, in particular a white paint on the mirror layer (with silver), in particular on a protective layer of the mirror layer, or a texturing of the peripheral zone opposite F6, forms the second diffusing zone or

- a metallic adhesive tape - mono or even double face on the masking layer or on the peripheral zone of the face F5 forms the first reflective zone

- And / or a metallic adhesive tape - mono or even double face on the mirror layer (with silver), in particular on a protective layer of the mirror layer, or on the peripheral zone of the face F6 forms the second reflecting zone .

The diffuse reflection layer according to the invention can be used to form the first diffusing zone or for the extraction of light in the central region.

The diffuse reflection layer, in particular white, preferably has a light reflection R _L greater than or equal to 80%. For example it is a painting, a lacquer, an enamel.

A lacquer is a non-transparent coating, generally opaque, and which can comprise at least one polymeric resin, at least one pigment, and generally mineral fillers. Polymeric resin is used to bind pigments and mineral fillers, while pigments are used to impart the desired color and opacity.

The lacquer can comprise, like any lacquer, a binder based on synthetic resin, of a polymeric nature. The binder is preferably based on acrylic resin, in particular crosslinked with melamine and / or an isocyanate. The binder can also be a polyurethane resin, obtained by crosslinking, with an isocyanate or a polyisocyanate, of hydroxylated resins, in particular polyester or polyether resins, or preferably acrylic resins (or polyacrylates). This particular combination makes it possible in particular to obtain low permeability to water, good mechanical properties (for example in terms of resistance to scratching).

The lacquer binder can also contain or be based on alkyd resin (s), obtained by chemical reaction between at least one polyol, at least one polyacid and at least one fatty acid or an oil. These alkyds are preferably short in oil, that is to say that the weight content of oil or fatty acid in the resin is preferably less than or equal to 40%. The polyols can be, for example, compounds of glycerol or pentaerithritol. The polyacids can be based on phthalic anhydride. The oils can be siccative (such as linseed, wood or Chinese oil), semi-siccative (such as soybean, tall oil, safflower or dehydrated castor oil), or even non-siccative (such as coconut or castor oil).

In order to improve their water resistance properties, the alkyd binders can also be modified by monomers such as styrene, vinyltoluene or acrylates or by phenolic or epoxy resins. Aminoplast alkyd resins which crosslink under the effect of heat are particularly advantageous binders for lacquer. The aminoplast crosslinker is preferably a ureaformol or melamine-formaldehyde resin, which confer good resistance to water, especially when they are made in an amount of 20 to 30% by mass relative to the dry alkyd binder.

The lacquer can also comprise a binder based on a thermosetting acrylic resin, for example obtained by crosslinking of an acrylic resin carboxylated with an epoxy, formo-phenolic or melamine-formaldehyde resin or an isocyanate, of an acrylic resin with carboxamide function by an epoxy or alkyd binder, or an acrylic resin with an epoxy function using acids or polyamines.

An adhesion promoter may preferably be present dispersed in the lacquer and / or in the form of a layer interposed between the lacquer layer and the bottom reflector plate. Glass adhesion promoters such as silanes can also be dispersed in the lacquer.

The lacquer can comprise pigments, mineral and / or organic, preferably mineral. Among the pigments used, there are for example titanium or zirconium oxides optionally doped with ions of transition elements, or also mixed oxides of the zircon type (ZrSiO ₄ ). The pigments are preferably free of heavy metals such as cadmium or lead.

The lacquer can also contain mineral fillers intended to optimize its physico-chemical parameters, for example its viscosity. The total content of mineral species (pigments and fillers) of the lacquer is preferably, expressed as a percentage by mass relative to the dry extract, of between 40 and 70%, or even between 50 and 60%.

The thickness of the lacquer is for example between 40 and 60 μm. The clarity L * can be at least 65.

Alternatively the masking layer (and / or respectively the mirror layer) is a reflective film bonded to the face F3 (and / or respectively the face F2) and capable of reflecting the rays at high angle coming from the group of diodes. In this case it forms the first reflecting zone (resp the second reflecting zone).

The first glazing and / or the second glazing and / or the internal glazing is a mineral glass glazing of thickness less than 4.5 mm and better than 3.5 mm or is made of plastic preferably chosen from polycarbonate, polymethacrylate of methyl thickness less than 4.5mm and better than 3.5mm.

The first or second glazing may be made of clear or even extra-clear mineral glass. For extra clear glass; reference may be made to application WO04 / 025334 for the composition of an extra-clear glass. One can choose in particular a silica-calcium lime glass with less than 0.05% Fe III or Fe ₂ O ₃ . We can choose, for example, Diamant® glass from SAINT-GOBAIN, Diamant Solaire® glass from SAINTGOBAIN, OptiWHITE® glass from Pilkington, B270® glass from Schott.

It may be by way of example, depending in particular on the aesthetic rendering or the desired optical effect and / or the destination of the mirror of:

- glass of standard composition, such as Planilux® glass from the company SAINTGOBAIN GLASS, of slightly green coloring,

- extra-clear glass without coloring (neutral) such as Diamant® and Diamant Solaire® glasses from the company SAINT-GOBAIN GLASS,

In a realization of the mirror:

a reflective metallic layer known as another mirror layer forms said masking layer, giving the mirror functionality on the face F4, in particular present in a central area of the second glazing and even occupying at least 50% and even at least 70% or at least 80% and even the entire face F4 (outside of the through hole (s)), preferably with a thickness of at most 0.2 μm, in particular a silver-based mirror layer

- (to have at least one other light area on the side F4 in the on state), the side

F4 locally has a surface roughness thus forming another contiguous diffusing textured area surrounded by the other mirror layer, another diffusing textured area of width W2 of at least 1cm and preferably of at most 5cm and of length L2> W2 , opposite this other diffusing zone and on the face F4 side, the second glazing having in the other diffusing textured zone a blur of at least 70% on the side F4, and even a light transmission T _L greater than 50%,

Preferably the group of diodes is spaced from one of the first and second glazing in particular by virtue of the profile and is against or glued to the other of the first and second glazing.

The support part of said group of diodes can be chosen from:

- a part which has a base carrying the PCB (with top or side emission diodes), preferably wider than the PCB

- a U-shaped part which has a base carrying the PCB (with top-emitting diodes) opposite the section T3 and on either side of the first and second wings, one on the side F2 ( or F3) and the other preferably on the F3 side (or F2)

- an L-shaped part which has a base carrying the PCB opposite the section T3 with top-emitting diodes) and a first wing on the face F3 or F2.

Preferably, for simplicity, the diodes of each group of diodes are chosen with the same (only) main direction of emission F.

And preferably, for uniform lighting, the diodes of each group are chosen with the same spectrum, mono or polychromatic.

The emission cone may for example be Lambertian.

In one embodiment, the mirror layer is a silver-based layer (even essentially silver, and typically coated with a protective layer). For example, the thickness of silver is at least 50 or 60nm and at most 150nm.

We prefer a mirror layer which is a deposit rather than an attached and glued film (metal film or plastic support carrying a reflective metal layer ...). The mirror layer can be part of a stack of layers directly on the face F2 comprising:

-under any layer / mirror layer / protective layer (monolayer or multilayer) in particular against corrosion like a paint, the assembly of first glazing and mirror layer has a light reflection R _L preferably greater than or equal to 85%, to 88% and even 90%, measured on the F1 side

Take for example a MIRALITE or MIRALITE EVOLUTION glass (with paint without the addition of lead) sold by the applicant company.

The other mirror layer on the face F3 can be identical to the mirror layer in particular as mentioned above.

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

The diode may for example be a semiconductor chip of size on the order of a hundred μm or mm; and possibly with minimal encapsulation, for example of protection. It is not necessary to use optics such as lenses directing the light emitted by the diode towards the privileged areas. The diodes can be embedded in a common protective material (waterproofing, dust, etc.).

Preferably, the diodes can thus be simple chips or with a low volume encapsulation in particular of SMD (“Surface Mounting Device” in English) or “Chip on Board” type rather than conventional, (first generation) bulky and low power and light efficiency.

One can foresee at least one of the following characteristics for the diodes:

- the side-emitting diodes are less than 5mm high, better than 4mm or even 2mm,

- the top emitting diodes are less than 1cm or 5mm in height

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 dimensions of the diodes,

- the number of diodes in the first group is at least equal to 10 or even 50.

The diode group can have a luminous flux of at least 900lm / W or even 1400lm / m (used alone) or at least 400 or 500lum / W (used with the other group of diodes).

The DC supply voltage can be 12V.

You may want a cool white (temperature of 600K).

The group or groups of diodes can be coupled to control means making it possible to emit light either permanently or intermittently, with different intensities, or of a given color, or of different colors, in particular depending on the amount of natural light.

The invention further relates to a furniture door (cupboard, cupboard), in particular for a water feature, formed by the lighting mirror according to the invention as described above.

The invention finally relates to a piece of furniture comprising:

- a part of furniture (cupboard, cupboard) with a bottom (against a wall), a base (normal to the wall) and first and second side walls (wood etc) called cheeks

- And at least one furniture door formed by said illuminating mirror according to the invention as described above, as well as the second ends of the first and second metal inserts (hinges) being on the first side wall (and also the power supply unit preferably electric).

FIG. 1f is a view of a piece of furniture provided with a lighting mirror door according to the invention

Figures 4a, 5b show illuminated mirror glazing with different diffusing textured areas.

It should be noted that for the sake of clarity the various elements of the objects (including the angles) shown are not necessarily reproduced to scale.

FIG. 1 schematically represents a view in longitudinal section of a light-emitting diode mirror 100 in a first embodiment of the invention.

The mirror 100 firstly comprises a first glazing called facade glazing 1, made of planar mineral glass preferably clear or extra-clear, for example a rectangular glass sheet, with a first main face 11 called face F1, and a second main face 12 forming the rear face called F2, and two sections 15,16. The glazing is preferably less than 4.5 mm thick.

The rear face 12 called F2 of the facade glazing is coated with a stack 2 comprising a metallic layer 20 based on silver (made by silvering) called the mirror layer, giving the mirror functionality on the front face, with a light reflection R _L at least 85%, itself coated with a protective layer 21 like a paint. For example, take a MIRALITE or MIRALITE EVOLUTION glass sold by the applicant company.

On the rear face 12 there is a diffusing textured area 32 t adjacent to the mirror layer 2 and surrounded by the mirror layer 2. The diffusing textured area 32 is in the form of a rectangular strip here of width W1 40mm.

The texturing is able to modify the light transmission of the facade glazing 1 for example so that it is between 40 and 85% on the front face of the mirror. Texturing prevents too intense transmission of the rays emitted by diodes, substantially reducing the glare of an individual looking towards the mirror 100.

The facade glazing 1 with the diffusing texturing 32 has a blur of at least 90% or even at least 95% on the front face of the mirror measured by Hazemeter in a conventional manner.

The diffusing texturing on the rear face 11 is preferably obtained by texturing the glass already coated with the mirror layer, in particular by sandblasting. You can also form the pattern by acidifying the glass as produced for Satinovo® glass from SAINT-GOBAIN GLASS.

The mirror 100 then comprises a second glazing T, made of planar mineral glass, preferably clear or extra-clear, for example a rectangular glass sheet, with a main face 11 ′ called face F2 on the side of face F2, and a main face 12 ′ forming the face the rear most known as F4, and two sections 15 ', 16'. The glazing T is preferably less than 4.5mm thick.

The face 13 of the second glazing is coated with a stack 2 ′ comprising for example a metallic layer 20 ′ based on silver (made by silvering) called another mirror layer, giving the mirror functionality on the face F4, with a light reflection R _L at least 85%, itself coated with a protective layer 21 'like a paint. Take for example a MIRALITE or MIRALITE EVOLUTION glass sold by the applicant company as for the first glazing.

Opposite 13 called F3, there is another textured diffusing zone 33 which is adjacent to the other mirror layer 2 ’and surrounded by the other mirror layer 2’. The diffusing textured zone 33 is in the form of a rectangular band of width W2 for example equal to W1 therefore here of 40mm

The texturing 33 is able to modify the light transmission of the second glazing T for example so that it is between 40 and 85% on the side F4 of the mirror. The diffusing texturing prevents too intense transmission of the rays emitted by diodes, substantially reducing the glare of an individual looking towards the mirror 100.

The second glazing is the same size as the first glazing. The faces F2 and F3 are facing each other, and the first and second glazing are spaced and associated at the periphery of the faces F2 and F3 by means of sealing with liquid water 7, masked by the mirror layer and masked by the other mirror layer on the face F3 in the form of an adhesive, opaque, for example black, polymeric strip flush with the edges 15 to 16 ′ of the glazing.

The total thickness E _T between the faces F1 and F4 is at most 13mm.

The edges of the glazing are visible, the illuminating mirror 100 has no frame.

To form a light area L1 on the face F1 and L2 side face F4 side, we choose to place between the first and second glazing 1.1 ’, in the internal space defined by the liquid water sealing means:

a first group of inorganic light-emitting diodes 4 (or LEDs) along a first longitudinal edge of the textured zone 32 in row on a support for electrical tracks called PCB 40, the PCB being on a metal L-shaped profile, the diodes each having a light emitting face 41 forming an angle of between 85 ° and 95 ° with the face F2, emitting face 41 perpendicular to the PCB 40 (“top emitting in English”)

- another group of inorganic light-emitting diodes 4 (or LED) along a second longitudinal edge of the textured zone 32 in row on a support for electrical tracks called PCB (40), the PCB being on a metal profile (51, 52), the diodes each having a light emitting face (41) forming an angle between 85 ° and 95 ° with the F2 face, emitting face 41 perpendicular to the PCB 40 ("top emitting in English")

- a glazing called internal glazing 1a transparent, in mineral glass here, preferably clear or extra-clear, with a main face 12a called F5 on the side facing F2, and a main face 13a called F6 on the side facing F3, a first section called T3 15a on the first side diode group, another section called T'3 16a next to another group of diodes.

Each light emitting face 41 of the first group of diodes being opposite the slice T3, the internal glazing being thus optically coupled with said first group of diodes, the distance between the slice T3 and each emitting face of the group of diodes 41 is less or equal to 2mm. Each light emitting face 41 of the second group of diodes being opposite the slice T'3, the internal glazing being thus optically coupled with said other group of diodes, the distance between the slice T3 and each emitting face of the group of diodes is less than or equal to 2mm.

The internal glazing also includes:

a central region 32a, facing the diffusing textured zone (and the other diffusing textured zone) of width W'1 at least equal to W1, comprising means for extracting light via the face F5 and / or the face F6, which are here a surface texturing of the face 12a called F5, for example by sanding or acidification a peripheral region 32b, on the side of the wafer T3 and contiguous to the central region, peripheral region opposite the mirror layer 20 (and the other mirror layer 20 ′), over a width D of at least 5mm and at most 20mm and preferably from 8 to 12mm from the edge of the central region and up to the edge T3 a other peripheral region 32c, on the side of the slice T'3 opposite to T3 and contiguous to the central region, other peripheral region opposite the mirror layer 20 (and the other mirror layer 20 '), over a width D d '' at least 5mm and at most 20mm and preferably 8 to 12mm from from the edge of the central region to the T’3 section.

The internal glazing here is 3mm thick.

To extract more light, four reflective adhesive strips are placed: two reflective adhesive strips facing the peripheral region 32b:

- the first 61 on the masking layer 21 ’of the face F3, in the form of a strip of width D1 equal to D and or even projecting towards the PCB

the second 62 on the protective layer 21 of the mirror layer, in the form of a strip of width D2 equal to D and or even projecting towards the PCB two reflective adhesive strips facing the other peripheral region 32c:

- the third 63 on the masking layer 21 of the face F2, in the form of a strip of width D3 equal to D and or even protruding in the direction of the PCB

- the fourth 64 on the masking layer 21 of the face F2, in the form of a strip of width D4 equal to D and or even protruding in the direction of the PCB.

The first PCB 40 is carried (by the rear) by a base 51 of the support profile 51 in L. A thermal conductive fastening material 54 is inserted here, which is for example glue or double-sided adhesive tape to obtain even better heat dissipation. The adhesive tape has the advantage of providing a calibrated thickness, allowing the PCB of the diodes to be perfectly flat and ensuring that the diodes are all equidistant from the textured area. In addition, the adhesive tape allows its prior fixing to the PCB. It is also possible to preferably use thermal grease between the PCB and the base 51 such as the compound CK4960® sold by the company Jetart.

The PCB 40 can be metallic. Then the diodes are soldered on tracks which are electrically insulated from the metallic material of the PCB. Since the metallic material of the PCB is thermal conductive, the PCB can be directly pressed against the thermal conductive base to obtain heat dissipation. The PCB can then be fixed to the base, for example by clipping and / or screwing, but a double-sided adhesive can be kept.

The diodes 41 are of the SMD type or of the “Chip on Board” type.

For uniform lighting, the diodes are chosen with the same visible spectrum, mono or polychromatic. We prefer white light (“cold” white).

The second glazing unit has a through hole 8 for the electrical supply, as detailed later, capable of accommodating a first insert emerging from the face F4 and attached to an electrical supply unit on the side of the face F4.

For example, each LED strip used is a strip sold by Neolux of 12V (reference: FLS-12V-1W4-580-60-02) composed of 100 LEDs / m of SMD 3528 type with a performance 1500lm / m .

Each reflective tape is made of smooth aluminum (acrylic adhesive) sold by Scapa with a thickness of around 300pm.

The peripheral sealing means are an adhesive strip which is an adhesive foam, here polyurethane of the Thermalbond V2100 type sold by Saint Gobain, the thickness of which is 3mm and width of about 15mm or even acrylic (black) like the tesa® product. ACXplus 70730.

Alternatively, a diffuse reflection layer is chosen which is a white paint deposited on the masking layer (air drying).

Figures 2, 3, 4, 4 ’show schematic sectional views of a light-emitting diode mirror in different embodiments of the invention.

Only the differences compared to the first embodiment are described

The lighting mirror 200 differs in that the internal glazing is not textured but is coated with a diffuse reflection layer 34 on the face F6 preferably preferably in full plate or at least in the central region facing the diffusing textured areas of the 1.1 'glazing.

You can choose 1 ’lacquered glazing like the Applicant’s white Planilaque product, 4mm or even 3mm thick.

Furthermore, in particular if the layer 34 is absent in the peripheral regions 32b and 32c, the reflective tape is replaced by four diffusing strips 61 ’to 64’, for example white paints on the faces F2 and F3.

Furthermore, as a peripheral sealing means 7 ′, a metal profile (steel, aluminum) was chosen with faces 71 and 72 bonded to the faces F2 and F3 by a tape 75 and a face 73 which may be aesthetic (finish layer or brushed aluminum etc) for example sold Nitto (product 501 F) of thickness around 300pm.

The lighting mirror 300 differs from the first lighting mirror 100 in that the diodes are emitted from the side and the profile 52 is a simple strip on the face F3

The illuminating mirror 400 differs from the first illuminating mirror 100 by the absence of the diffusing textured zone of the face F3, a layer in diffuse reflection on the face F6 and a smooth face F5.

It can be a lighting mirror to be fixed on a wall; the insert 9 linked to the housing 90 against the face F4 is no longer a hinge. Furthermore, at least one fixing hook 93 is used, for example with a fixing hole 81

The lighting mirror 400 ’differs from the last lighting mirror 400 in that the insert 9 is also used for fixing (with a fixing hole 81) and for removing the internal glazing. Also, a reflective tape 65 is preferably used opposite the diffusing textured zone and beyond, opposite the mirror layer (strips 61 and 63).

FIGS. 4a, 5b show glazing with illuminating mirror with different diffusing textured zones 32 of the face F2.

In FIG. 4a, the light strip L1 is in L and it is chosen to join two internal glazings 1a and 1b in L (dotted because masked).

The peripheral sealing means 7 frame the mirror (dotted because hidden).

In FIG. 4b, the light strip L1 comprises three spaced diffusing patterns 32 and a single internal glazing 1a rectangular is chosen (dotted because hidden).
