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.

• between the first and second glazings, a (first) group of inorganic light-emitting diodes, in a row on a support of electrical tracks called PCB (especially parallelepipedal PCBs, preferably with a thickness of at most 3 mm, in one or more aligned pieces, even butted along the textured zone T3), the PCB being preferably on a profile preferably of metal, in particular of U-shaped or L-shaped section forming in particular heat sink, the diodes of the group (forward or side emission) each having a light-emitting face forming an angle of between 85 ° and 95 ° with the face F2 and even between 88 ° and 92 ° in particular a group of diodes along an edge of the diffusing textured area, in particular the light coming from said (first) group of diodes leaving by the face F1 and possibly by the face F4.

In addition, the faces F2 and F3 are facing each other, and the first and second glazings are spaced apart and associated at the periphery of the faces F2 and F3 by masked liquid water sealing means (face side F1) by the layer mirror and masked (face side F4) by a masking layer opposite F3 -which may be another mirror layer or an opaque layer possibly diffusing possibly on another mirror layer.

Preferably, the edges CT1 and CT2 (in particular polished, flat), are visible and the watertight means are flush with edges CT1 and CT2 or recessed by at most 5 or 2mm or even 1mm, means of sealing. liquid watertightness of width preferably at least 10mm and better at most 40mm or 30mm.

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

Finally, the group of diodes, the PCB, the metal section are spaced apart from the liquid water sealing means, the group of diodes, the PCB and the metal section (and even the internal connections for the group of diodes), internal because in the internal space between the faces F2 and F3) being between the mirror layer and the masking layer.

The illuminating mirror further comprises a so-called internal glazing, transparent, mineral or organic glass (preferably clear or extraclair), between the faces F2 and F3, with a main face called F5 facing the face F2, and a face main said F6 facing the face F3 and a first portion said T3, the inner glazing being in the internal space delimited by the sealing means with liquid water, glazing internal thickness Eg at most 4.5mm or better at most 3.5mm and preferably greater than the height of the emitting faces for example at least 2mm or 2.5mm.

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

• une région centrale en regard de la zone texturée diffusante, de largeur W'1 au moins égale à W1, comprenant des moyens d'extraction de la lumière via la face F5 et/ou la face F6, qui sont des moyens de diffusion en surface de la face F5 et/ou la face F6 ou des moyens de diffusion en volume dans le vitrage interne, par exemple une région centrale en forme de bande rectangulaire

• de préférence (si autre groupe de diodes associé) une autre région périphérique contiguë à la région centrale, région périphérique opposé à ladite région périphérique en regard de la couche miroir (et de la couche de masquage) sur une largeur D' -entre le bord de la région centrale et une tranche T'3 du vitrage interne opposé à T3- d'au moins 5mm et d'au plus 20mm et de préférence de 8 à 12mm

The internal glazing comprises:

• a central region facing the 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 surface diffusion means of the face F5 and / or the 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-d 'at least 5mm and not more than 20mm and preferably 8-12mm

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 of thickness (height) of at least 2 mm especially if the internal glass is incorporated in the internal space.

Thus, the invention provides an illuminating mirror which is compact, protected in particular projections (water, in a room like the bathroom etc.) and whose rear is not dangerous.

In addition, the illuminating mirror retains design flexibility for the shape and extent and location of the diffusing textured area. The diffused textured area avoids dazzling. 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 cleaned.

The inner 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. Internal glazing improves light extraction.

We may wish decorative or functional lighting, including at least 100 lux to 1m face F1 side.

The illuminating mirror does not need a particular metal 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 glazings made opaque outside light zone.

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

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

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

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

• une texturation diffusante de la face F5 ou F6 du vitrage interne, notamment en verre minéral, par exemple un verre sablé
• une couche diffusante notamment à réflexion diffuse sur la face F6 du vitrage interne en verre minéral, par exemple une peinture blanche (laissant passer de la lumière côté face F3 ou non)

Preferably, the light extraction means are chosen from:

• a diffusing texturing of the face F5 or F6 of the internal glazing, in particular of mineral glass, for example a sandblasted glass
• a diffusing layer including diffuse reflection on the face F6 of the internal glass of mineral glass, for example a white paint (letting F3 side light or not)

For example, the diffusing textured zone may be a diffusing band (full) or has scattering patterns (cloud, star, geometric pattern, etc.) spaced at least 5 cm apart (inscribed in a band) along a slice of the glazings and T3 is a longitudinal slice along the diffusing band or the area covering the scattering patterns.

• et/ou une couche à réflexion diffuse, notamment une peinture blanche sur la couche miroir (à l'argent), en particulier sur une couche de protection de la couche miroir, ou une texturation de la zone périphérique en face F6, forme la deuxième zone diffusante
  ou
• un ruban adhésif métallique -mono ou même double face sur la couche de masquage ou sur la zone périphérique de la face F5 forme la première zone réfléchissante

et/ou un ruban adhésif métallique -mono ou même double face sur la couche miroir (à l'argent de préférence), en particulier sur une couche de protection de la couche miroir, ou sur la zone périphérique de la face F6 forme la deuxième zone réfléchissante.La couche à réflexion diffuse selon l'invention peut être utilisée pour former la première zone diffusante ou pour l'extraction de lumière en région centrale.In this last 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 (silver), in particular on a protective layer of the mirror layer, or a texturing of the peripheral zone on the face F6, forms the second diffusing area
  or
• a metal adhesive tape -mono or even double-sided on the masking layer or on the peripheral zone of the face F5 forms the first reflective zone

and / or a metal-mono or even double-sided adhesive tape on the mirror layer (preferably with silver), in particular on a protective layer of the mirror layer, or on the peripheral zone of the face F6 forms the second Reflective 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 central region.

The diffuse reflective layer, especially 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 may comprise at least one polymeric resin, at least one pigment, and generally mineral fillers. The polymeric resin serves to bind the pigments and mineral fillers, while the pigments are intended to impart the desired color and opacity.

The lacquer may comprise, as 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 may also be a polyurethane resin, obtained by crosslinking, by an isocyanate or a polyisocyanate, of hydroxylated resins, in particular polyester resins or polyethers, or preferably acrylic resins (or polyacrylates). This particular combination makes it possible in particular to obtain low water permeabilities, good mechanical properties (for example in terms of scratch resistance).

The binder of the lacquer may 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 may be, for example, glycerol or pentaerythritol compounds. The polyacids may be based on phthalic anhydride. The oils can be drying (such as linseed oil, wood or china oil), semi-drying (such as soybean oil, tall oil, safflower or dehydrated castor oil), or non-drying (such as coconut oil or castor oil). In order to improve their water resistance properties, alkyd binders can also be modified by monomers such as styrene, vinyltoluene or acrylates or by phenolic or epoxy resins. Heat-curing aminoplast alkyd resins are particularly advantageous binders for lacquer. The aminoplast crosslinking agent is preferably a urea-formaldehyde or melamine-formaldehyde resin, which gives good resistance to water, especially when they are provided at a rate of 20 to 30% by weight relative to the dry alkyd binder.

The lacquer may also comprise a binder based on a thermosetting acrylic resin, for example obtained by crosslinking an acrylic resin carboxylated with an epoxy resin, formophenol or melamine-formaldehyde or an isocyanate, with a carboxamide-functional acrylic resin. an epoxy or alkyd binder, or an epoxy-functional acrylic resin with acids or polyamines.

An adhesion promoter may preferably be present dispersed in the lacquer and / or as a layer under the lacquer layer and the plate. Adhesion promoters with a glass, such as silanes, can also be dispersed in the lacquer.

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

The lacquer may also contain mineral fillers intended to optimize its physicochemical parameters, for example its viscosity. The total content of mineral species (pigments and fillers) of the lacquer is preferably, expressed as a percentage by weight relative to the solids content, of between 40 and 70%, and even between 50 and 60%.

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

• un ruban adhésif métallique double face sur la couche de masquage (par exemple miroir, à l'argent) et sur la zone périphérique de la face F5 qui forme la première zone réfléchissante,
• un ruban adhésif métallique double face sur la couche de masquage et sur une autre zone périphérique de la face F5 par exemple à l'opposé de la première zone réfléchissante
  et/ou
• un ruban adhésif métallique double face sur une couche de protection de la couche miroir (à l'argent de préférence) et sur la zone périphérique de la face F6 qui forme la deuxième zone réfléchissante
• un autre ruban adhésif métallique double face sur une couche de protection de la couche miroir et sur une autre zone périphérique de la face F6 par exemple à l'opposé de la deuxième zone réfléchissante.

The double-sided metal tape can be used to position the inner glazing. We can use for example at least two, even three or four:

• a double-sided metallic adhesive tape on the masking layer (for example mirror, silver) and on the peripheral zone of the face F5 which forms the first reflective zone,
• a double-sided metal adhesive tape on the masking layer and on another peripheral zone of the face F5 for example opposite the first reflective zone
  and or
• a double-sided metallic adhesive tape on a protective layer of the mirror layer (preferably silver) and on the peripheral zone of the face F6 which forms the second reflective zone
• another double-sided metal adhesive tape on a protective layer of the mirror layer and on another peripheral zone of the face F6 for example opposite the second reflective zone.

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

Furthermore, advantageously, the second glazing comprises at least a first through hole of 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 housing, and preferably housing, a first insert (preferably metal) coming out face F4 and attached to a power supply box face side F4 (standalone box or power adapter).

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

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

The first insert is particularly hollow, for example plastic, can be used to hide (house) electrical wiring (for example electrically isolated from the insert if metal) to the power supply box.

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

The second glazing may comprise a second through-hole, preferably identical to the first-preferably spaced apart 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 as through hole with insert as needed preferably identical to the first through hole with first insert.

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

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

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

The electrical contact between the first internal connector and the first metal insert preferably on a particularly protruding area of the first face-side insert F3 (and even between the second internal connector and the second metal insert) comprises the choice: a solder, a conductive bonding or a mechanical contact (screwing, clipping, plugging, etc.)

The other mirror layer F3 face may be identical to the mirror layer especially as mentioned above.

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: protection of the oxidation and humidity, conversion of wavelength, diffusing element.

The diode may for example be a semiconductor chip of the order of one hundred microns 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.

The figure 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 first comprises a first glazing unit called front glazing 1, made of flat or preferably extraclear mineral glass, for example a rectangular glass sheet, with a first main face 11, said F1 face, and a second main face 12 forming the so-called rear face F2, and two slices 15,16. The glazing is of thickness preferably less than 4.5 mm.

The rear face 12 called F2 front glazing is coated with a stack 2 comprising a metal layer 20 based on silver (made by silvering) said mirror layer, giving the mirror function on the front face, with a light reflection R _L at least 85%, itself coated with a protective layer 21 as a paint. Take for example a glass MIRALITE or MIRALITE EVOLUTION sold by the applicant company.

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

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 side of the mirror. The texturing prevents too intense transmission of the rays emitted by diodes, substantially reduce the glare of an individual looking towards the mirror 100.

The facade glazing 1 with diffusing texturing 32 has a blur of at least 90% or even at least 95% on the front side 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. The pattern can also be formed by acidifying the glass as produced for the SAINT-GOBAIN GLASS Satinovo® glass.

The mirror 100 then comprises a second glazing 1 ', made of flat mineral glass, preferably clear or extraclear, for example a rectangular glass sheet, with a main face 11' called face F2 face side F2, and a main face 12 'forming the rearmost face said F4, and two slices 15 ', 16'. The glazing 1 'is preferably less than 4.5mm thick.

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

In face 13, said F3, is present another diffusing textured 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 strip of width W2 for example equal to W1, so here 40mm

The texturing 33 is able to modify the light transmission of the second glazing 1 'for example so that it is between 40 and 85% face side F4 of the mirror. The diffusing texturing prevents too intense transmission of the rays emitted by diodes, substantially reduce 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 glazings are spaced apart and associated at the periphery of the faces F2 and F3 by liquid water sealing means 7, masked by the mirror layer and masked by the other mirror layer opposite F3 in the form of an adhesive polymeric strip, opaque, for example black flush with the edges 15 to 16 'glazing.

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

The songs of the windows are visible, the illuminating mirror 100 is devoid of framing.

• un vitrage dit vitrage interne 1a transparent, en verre minéral ici, de préférence clair ou extraclair, avec une face principale 12a dite F6 côté face F2, et une face principale 13a dite F5 côté face F3, une première tranche dite T3 15a coté premier groupe de diodes, une autre tranche dite T'3 16a côté autre groupe de diodes.

To form a luminous area L1 face side F1 and L2 face side F4, it is chosen to place between the first and second glazings 1,1 ', in the internal space delimited 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 a row on an electrical track support said PCB 40, the PCB being on an L-shaped metal section, the diodes having each 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")
• another group of inorganic light-emitting diodes 4 (or LEDs) along a second longitudinal edge of the textured zone 32 in a row on an electrical track support said PCB (40), the PCB being on a metal section (51, 52 ), the diodes each having an emitting face (41) of light forming an angle of between 85 ° and 95 ° with the face F2, emitting face 41 perpendicular to the PCB 40 ("top emitting")

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

• une région centrale 32a, en regard de la zone texturée diffusante (et de l'autre zone texturée diffusante) de largeur W'1 au moins égale à W1, comprenant des moyens d'extraction de la lumière via la face F5 et/ou la face F6, qui sont ici une texturation de surface de la face 12a dite F5, par exemple par sablage ou acidage
• une région périphérique 32b, du côté de la tranche T3 et contiguë à la région centrale, région périphérique en regard de la couche miroir 20 (et de l'autre couche miroir 20'), sur une largeur D d'au moins 5mm et d'au plus 20mm et de préférence de 8 à 12mm à partir du bord de la région centrale et jusqu'à la tranche T3
• une autre région périphérique 32c, du côté de la tranche T'3 opposée à T3 et contiguë à la région centrale, autre région périphérique en regard de la couche miroir 20 (et de l'autre couche miroir 20'), sur une largeur D d'au moins 5mm et d'au plus 20mm et de préférence de 8 à 12mm à partir du bord de la région centrale et jusqu'à la tranche T'3.

The internal glazing further comprises:

• 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 so-called F5 face 12a, for example by sanding or acidifying
• a peripheral region 32b, on the side of the slice T3 and contiguous with the central region, peripheral region opposite the mirror layer 20 (and the other mirror layer 20 '), on a width D of at least 5 mm and not more than 20mm and preferably from 8 to 12mm from the edge of the central region to the T3 range
• another peripheral region 32c, on the side of the slice T'3 opposite to T3 and contiguous to the central region, another peripheral region facing the mirror layer 20 (and the other mirror layer 20 '), on a width D at least 5mm and not more than 20mm and preferably 8-12mm from the edge of the central region to the T'3 wafer.

• deux bandes adhésives réfléchissantes face à la région périphérique 32b :
  • la première 61 sur la couche de masquage 21' de la face F3, sous forme d'une bande de largeur D1 égale à D et ou même dépassant en direction du PCB
  • la deuxième 62 sur la couche de protection 21 de la couche miroir, sous forme d'une bande de largeur D2 égale à D et ou même dépassant en direction du PCB
• deux bandes adhésives réfléchissantes face à l'autre région périphérique 32c :
  • la troisième 63 sur la couche de masquage 21' de la face F3, sous forme d'une bande de largeur D3 égale à D et ou même dépassant en direction du PCB
  • la quatrième 64 sur la couche de protection 21 de la couche miroir sur laface F2, sous forme d'une bande de largeur D4 égale à D et ou même dépassant en direction du PCB.

The internal glazing is here of thickness equal to 3mm.
To extract more light, four reflective tapes are placed, such as reflective scotches:

• 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 band of width D1 equal to D and or even exceeding in the direction of the PCB
  • the second 62 on the protective layer 21 of the mirror layer, in the form of a band of width D2 equal to D and or even exceeding in the direction of the PCB
• two reflective adhesive strips facing the other peripheral region 32c:
  • the third 63 on the masking layer 21 'of the face F3, in the form of a band of width D3 equal to D and or even exceeding in the direction of the PCB
  • the fourth 64 on the protective layer 21 of the mirror layer on the surface F2, in the form of a band of width D4 equal to D and or even exceeding in the direction of the PCB.

All or part of the metal adhesive tapes (for example two, three or four) may alternatively be double-sided, in particular to position and immobilize the internal glazing 1a, for example first and third band 61 and 63 and / or second and fourth bands 62 and 64 are also glued to the glazing facing (first or second glazing).

The first PCB 40 is carried (from the rear) by a base 51 of the L-shaped support section 51. A thermal conducting fastening material 54 is interposed here, which is, for example, glue or double-sided adhesive tape to obtain still better heat dissipation. The adhesive tape has the advantage of providing a calibrated thickness, allowing the diode PCB to be perfectly flat and to ensure that the diodes are all equidistant from the textured area. 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 51 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.

For uniform illumination, the diodes are chosen with the same spectrum in the visible, mono or polychromatic. We favor a white light ("cold" white).

The second glazing comprises a through hole 8 for the power supply, as detailed later able to accommodate a first insert exiting face F4 and attached to a face-side power supply box F4.

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

Each scotch reflector is smooth aluminum (acrylic adhesive) sold by Scapa about 300μm thick

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

Alternatively one chooses a diffuse reflective layer which is a white paint deposited on the masking layer (air drying).

The group of diodes on PCB 40 is electrically powered at a DC voltage of 12V.

The first internal connector has a first metal foil 80 for example copper bonded to the face F3. The first metal foil is connected to a first electrical wire 8a at the output of the PCB 40, for example a wire of short length (for example from 2 to 10 cm).

The figures 2 , 3, 4, 4 ' are schematic sectional views of a light emitting diode illuminating mirror in different embodiments of the invention.Only the differences are described.
The illuminating mirror 200 differs in that the internal glazing is not textured but is coated with a diffuse reflective layer 34 facing F6 preferably preferably in full plate or at least in the central region facing the diffused textured areas of the glazing 1, 1 '.
One can choose a lacquered glass 1 'as the Planilaque white product of the plaintiff of 4mm or even 3mm thick.
Moreover, in particular if the layer 34 is absent in the peripheral regions 32b and 32c, the reflective scotches are replaced by four diffusing strips 61 'to 64', for example white paints on the faces F2 and F3.
Furthermore, a metallic profile (steel, aluminum) with faces 71 and 72 bonded to the faces F2 and F3 by a Scotch 75 and a face 73 which may be aesthetic (topcoat or brushed aluminum etc), Scotch 75 for example sold by Nitto (product 501F) of thickness 300μm approximately.

The illuminating mirror 300 differs from the first illuminating mirror 100 in that the diodes are emission 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 area of the face F3, a diffuse reflective layer on the face F6 and a smooth face F5.
It can be a mirror to fix on a wall; the insert 9 connected to the housing 90 against the face F4 is no longer a hinge. One or more fastening hooks 93 are also used, for example with an attachment hole 81.

The illuminating mirror 400 'differs from the last illuminating mirror 400 in that the insert 9 also serves for fixing (with a fixing hole 81).
