    [0001] The present invention relates to the insulating glazings of a refrigerated furniture door, and in particular to a luminous glazed unit for a refrigerated furniture door, the door with such an assembly and the piece of furniture with a refrigerated cabinet door. such door, and its manufacture. An insulating glazing unit is known for opening a refrigerated enclosure, an enclosure in which cold or frozen products, such as food products or beverages, or any other products requiring conservation in the cold, for example products, are exposed. pharmaceuticals or even flowers. The insulating glazing consists of at least two glass substrates separated by a gas strip and provided for at least one of them with a low emissive coating. When products kept in a refrigerated enclosure must remain visible as is the case in many commercial premises today, we equip the refrigerated enclosure of glass parts that transform it into a refrigerated "showcase" whose common name is "refrigerated cabinet of sale ". There are several variants of these "showcases". Some are cabinet-shaped and then the door itself is transparent, others are chests and it is the horizontal cover (door horizontally) that is glazed to allow observation content.
    [0002] The light function is usually inside the speaker. More recently in the application W02013 / 017792 is proposed an illuminated refrigerated furniture door comprising an insulating glazing electroluminescent diodes optically coupled to the edge of one of the two glasses and whose door mounting profile is hollowed out to insert the diodes via a cover masking this recess of the profile. Also, the present invention aims a light insulating glazing refrigerated furniture door to light source and ecological efficient (light-emitting diodes, optical fiber (s) coupled to one or more diodes for example), robust and reliable, without need to modify the door profile.

    [0007] Preferably, the fixing piece and / or the bottom piece or the second wafer protects the light source from misalignment and / or crushing against the injection edge, particularly during the assembly of a profile. 'framing. For the protection function (mechanical) of the source, the fixing piece or the second wafer (protruding from the injection edge) may be protruding from the source support or the optical fiber directly on the bottom piece, projecting from the side opposite to the injection edge.

More generally, the fastener-bottom piece and cover assembly is preferably dimensioned and arranged to protect (the source support and) the source of the adhesive during assembly of the frame profile. If the glue is present in a corner between the injection edge and an adjacent edge, it is preferred to supplement the protection with an additional lateral piece on the lateral end.

Preferably, the diodes are not attached to the injection edge (double-sided tape or glue) or must be pre-encapsulated The fastener may be a straight piece on a single edge of the insulating glass. The fastener may also be an angled L-shaped member for attachment to the first seal also at an edge of the separate glazing and adjacent to the injection edge.
    [0009] The fastener may also be a frame in several pieces (abutments), for example two pieces L or four pieces. Indeed, it is desirable to illuminate by injection of light on two adjacent edges, two opposite edges or on the three or four edges.

Preferably, to avoid a thermal bridge, the fastener which is metallic is not in contact with both the first glazing and the second glazing. For optimum protection against glue and / or mechanical protection, the fastener is preferably of length L1 at least substantially equal to the length L of the injection edge or at least the length of the light source, if on a limited area of the injection edge. The source support is of length less than or equal to L1 (absent corner area, without glue) and preferably slightly less than or equal to L. A heat sink metal under the source support may be the fastener, the bottom room or hood. In the case of the optical fiber the source support can be directly the fixing piece and / or the bottom piece.

The source support (printed circuit board) is preferably less than the thickness of the injection edge plus 1 mm.
    [0012] With lateral emitting diodes ("side emitting" in English), the emitting faces are opposite the injection edge and the source support (printed circuit board) parallel to the external face and preferably against the fastener part. playing the role of heat sink or even is confused with the fastener (without disassembly possible).
    [0013] Preferably, the light source extends along the injection edge to avoid dark areas. The length of the light source is substantially equal to the length of the injection edge. The bottom piece is preferably: - metallic and thick if it plays the role of heat sink (rear of the source support, in contact) - reflective to redirect the rays, in particular metallic or polymer (hard preferably) metallized - a profile as a flat - a simple form: rectangular section (extended by a possible cover) - with an inner wall facing the plane injection edge, parallel to the middle plane of the first sheet. The bottom piece is preferably of length L5 at least substantially equal to the length L of the injection edge (absent from the corner area, without glue) and preferably slightly less (of at most 20 mm or equal to L) and more preferably equal to the length L4 of the fastener. The bottom piece is preferably of thickness Ep5 of at least 0.8 mm and even at least 1 mm and better still at least 1.5 mm, for example a metal sheet (aluminum etc.), Ep5 being able to be equal to to Ep4 (monolithic piece in particular and with separate cover or not).

The VV5 width of the bottom piece may be slightly greater than the thickness of the first sheet (especially if single glazing) to house the top-emitting diode support typically typically 5mm wide VV2. The bottom piece can be a straight fastener on a single edge of insulating glass.
    [0014] Like the fixing piece, the bottom piece can also be opposite an edge of the separate glazing unit and adjacent to the injection edge or even other edges: - an angled L-piece - or abutments (at the corner, etc.) ) for attachment to the first seal also at an edge of the separate glazing and adjacent to the injection edge - or a frame in one piece (bent at the four corners) or in several butted pieces. Indeed, it is desirable to illuminate by injection of light on two adjacent edges, two opposite edges or on the three or four edges.
    [0015] For simplicity preferably the bottom piece is against, better secured to the fastener (for sealing against the glue) even if it can also be against, better secured to the second glazing (for sealing against the glue) including second glazing protruding ( for mechanical protection). Advantageously, for simplicity, the bottom piece extends the fastener forming a monolithic piece metal (or metallized), including a folded sheet - aluminum- in particular bottom piece forms a lateral recess of the fastener. When the second protruding edge of the injection edge protrudes from the source carrier or the optical fiber directly onto the bottom piece, protruding from the injection edge, and the source carrier is directly in adhesive contact with the first seal possibly confused with the fastener. In particular, the source support is a printed circuit board and the source of the side-emitting diodes. The source medium, in particular a printed circuit board or `PCB ', may preferably be in a cavity (laterally open) formed by the injection edge, the bottom piece and the fastener, and is in non-adhesive contact with the metal bottom piece or the metal fastener, or carried by the metal cap which can be dismountable or further extending the metal bottom piece.

    [0017] The source medium (printed circuit board) is preferably not embedded in a polymeric encapsulation (and with the diodes). The source support and / or the optical fiber is then simply against the bottom piece and / or fixing spaced or not the injection edge. Preferably, before installation of the frame profile (with glue), it is possible to add a cover closing a cavity (laterally opening) delimited by the injection edge, the fixing piece and the bottom piece, preferably against or integral with the fastener, housing the light source (and the source support, especially diodes) closure in the longitudinal direction of the injection edge, preferably metal cover (or metallized).
    [0018] The cavity is not closed laterally, it has open lateral ends. It is not necessary to disassemble the cover even if you want to disassemble the source (disassembly laterally). The hood can be fixed (one or two sides) without being disassembled.
    [0019] In a first (preferred) embodiment, the cover may be metallic (aluminum), or metallized plastic (or other light reflecting layer), glued (double-sided adhesive, glue) or against the outer face (typically over at most one width 15mm from the injection edge) by creating an allowance of at most 1.5mm and even at most 1mm or even at most 0.5mm. Indeed, it should not too far out of the frame profile of the first glazing. The hood is preferably of thickness of at most 250pm and even 100pm 50pm. The cover can be flexible, the source support (preferably diodes) is then preferably against the bottom piece or the fastener.
    [0020] The hood and the bottom piece can form a monolithic piece. The cover may be metallic or preferably metallized (or other light reflective layer), in particular adhesive at one or at the ends or over the entire surface, with a portion bonded to the external face, creating an excess thickness of at most 1 mm and even 0.5m or 0.2mm (double sided or glue), extending to form the bonded back piece or against the fastener. the bottom piece is glued or against the fastener or the bottom piece is spaced from the fastener and extends to be against or glued to the second glazing. And the second slice may be protruding from the source support or the optical fiber directly on the bottom piece, protruding from the opposite side of the injection edge. The cover may extend the bottom piece then bent, the fastener assembly- bottom-cover part being a monolithic metal part the end of the cap being against the first face preferably without fixing means (adhesive etc.). It is preferred that Ep4 is at least 1 mm better 1.5 mm (mechanical protection) and the cover creating an extra thickness of at most 1 mm on the outer face. It can be an extruded part.
    [0021] The cover can extend the bottom part then bent, the set-fixing piece-bottom-cover part being a monolithic metal part, the end of the cover (edge of its main side glazed side) preferably against (affixed) the external face (usually the first face) -and better without adhesive or any means of attachment to facilitate its implementation. The source and / or the source support are then mounted (by sliding) via a lateral end (open) of the opening cavity of the source. Preferably, at least one of the following features is provided: - the assembly of the fastening part-bottom part-cover, if any, is associated with the insulating glazing without creating a thermal bridge, - the assembly of the fixing piece-bottom piece -Capot eventual is a reflector, metallic or metallized, - there is another injection edge (other sources and fasteners and bottom and even a hood) opposite the injection edge preferably on an edge of the first leaf (if first laminated glass). Preferably illuminates at least on a longitudinal edge (vertical for conventional speaker door) and as a function of the width of the glazing on the opposite edge. Of course, it is possible to duplicate the means and to provide, in a similar or identical manner, second fixing pieces, second bottom piece, second cover, second source support, second light source, for light injection lighting - in the edge of the first sheet adjacent to the injection edge (lateral edge for example) - in the edge of the first sheet opposite to the injection edge (longitudinal edge for example) can even provide all of these means on each edge of the first leaf. Of course, it is possible to duplicate the means and to provide, in a similar or identical manner, second fixing pieces-second bottom piece-second cover-second source support-second light source for lighting by injection of light into the edge of the second sheet adjacent to the injection edge - in the edge of the first sheet opposite the injection edge (longitudinal edge for example).
    [0022] The second fastener may be contiguous to the first which is then reduced in width accordingly for example by half so that the two are one ¬ opposite the first seal. Alternatively the second fastener is merged with the fastener. In case (for future addition of diodes), the fastening profile may comprise an identical or similar side-side side extension (less wide if less thick glass sheet for example) opposite the bottom piece, the together being monolithic with fixing piece forming the central body preferably of rectangular section and the bottom piece and the extension two symmetrical wings including flat rectangular section or L (return to the inner face of the glazing). In the present invention, the term bonding involves a glue or double-sided adhesive tape; the term glue does not cover a double-sided tape. Preferably, the glazed assembly comprises a frame profile comprising a frame amount, facing the injection edge and on at least the internal face or the external face fixed to the insulating glazing by gluing preferably by a so-called glue mounting (rather than a double-sided adhesive at least on both glasses). And so preferably it is in adhesive contact by the glue with the fastener (back side), and even in adhesive contact by glue with the bottom piece (back side) and the cover (back side). Possible mounting glue is absent from the space between the light source and the injection edge (in the cavity housing the source and source support). The framing profile is preferably associated with the insulating glazing without creating a thermal bridge. It is preferred that it has a metal part on the outer face. The amount of frame preferably comprises: a first part (bent, section L ...) in particular metal, opposite the injection edge and protruding on the external face, glued to the outer face and preferably glued to the fastener, which is offset from the second glazing (not facing), and a second part, in particular thermal insulating, preferably polymeric, secured by bonding means with the first part, facing the second edge adjacent to the edge; injection and eventually exceeding the inner face (glued to the inner face).
    [0023] One of the parts is metallic (preferably first part, user side) the other being thermal insulation preferably polymeric preferably second part, pregnant side). The first or second part may have a hollow area.
    [0024] In an advantageous embodiment, the second slice is protruding from the injection edge and preferably protrudes from the source support or the optical fiber directly on the bottom piece, protruding from the side opposite the injection edge, the amount of frame includes a return to the inner face, in particular is L-section, and the inner face comprises masking means of the first seal (and the spacer, generally metallic, attached), masking means preferably in mineral material, such as enamel, having an optical density of at least 2 and even at least 2.5. The frame profile may be a frame preferably in several pieces (bent, abutments in particular at the corners of the insulating glazing, bevel ..) The frame profile may further comprise, preferably the horizontal amount, in particular on a post an edge adjacent the injection edge (preferably longitudinal and vertical injection edge when mounted and adjacent edge horizontal and high when mounted) a recess covered by a blanket (eg flat piece) leaktight and with watertight means sealing (infiltrations if condensation on the glass door), the assembly preferably allowing the passage of power supply son of the source, the cover and / or the sealing means (seal etc) being removable and forming a trap access to the source, without the presence of mounting glue between this flap and the source housed in the outlet cavity laterally, without adhesive contact or at least permanent attachment).
    [0025] The recess and the hole are dimensioned to be able to exit the source and preferably its source support as the printed circuit board distinct from the bottom piece. The source is for example removable by the aid of said son laterally to the cavity.
    [0026] The cover may be a part fixed, preferably by gluing, to the frame profile and further comprising a pivot (for a door opening to the outside of the enclosure). The profile may preferably be glued by an adhesive to the frame. insulating glazing and the glue is absent between the access door and the lateral end closest to the opening cavity. If the door is a refrigerated trunk lid in particular, the glazings can be curved, and it is preferable that the profile be frame is flexible material to adapt to curvatures. The invention naturally also relates to a professional refrigerated furniture door (cold positive, cold negative) comprising a luminous glazed assembly as described above and the refrigerated enclosure with such a door. Preferably the injection edge is the longitudinal edge, and vertical after installation of the door, the recess is on a frame amount opposite a side edge and upper after installation of the doorLa porte is preferably opening ( to outside the enclosure) and comprises for this purpose a pivot on the top of the upper frame profile. The enclosure may comprise two or more glazed doors Naturally, the insulating glazing unit may comprise, as a thermal function layer: an anti-frost layer, and / or an emissive or "low E" layer (silver stacking, preferably a single layer of silver), preferably on the second face in a double-glazed version (first laminated glazing or not, preferably second single glazing) or triple glazing and even on the internal face for triple glazing - and / or heating layer, on the inner face for the triple glazing From a cavity of given width (bottom piece distance and predetermined injection edge) the invention allows a good positioning of the diode with respect to the injection zone light.
    [0027] The face or emitting area (for the diode, preferably chip with its pre-encapsulation - silicone type etc) can approach in a controlled manner as close as possible to the injection edge without risk. Preferably, the positioning of the source support (and preferably of the carrier cover or not of the support) is not done under stress because it implies too much deformation and thus does not allow precise control of the position: there is not one possible position, but several. Preferably, any adhesive system (glue), even reversible, as well as any forced mounting of the source support is avoided. The at least one diode support (or even the chips) is provided, advantageously before it is integrated into the glazing (during their manufacture, etc.), with at least one monolayer or multilayer protection layer against humidity and / or encapsulation such as a silicone, epoxy or acrylic type varnish. More specifically, the protective layer protects at least printed circuit board, welds, connectors if not sealed.
    [0028] The diodes (at least the emitting face) are preferably not protected and if already covered (pre-encapsulated) silicone. The LED strips are protected before integrating into the housing). The protection can be of the type of protection varnish (silicone, epoxy, acrylic ...), encapsulation or "potting" of the bar of LEDs (silicone, epoxy, acrylic ...).
    [0029] We can mention the tropicalization varnish sold by Syneo, with an acrylic base or PU or Silicone and 3M layer "Novec Electronic coating EGO 1700". We can mention the protective varnish Abchimie. The removal is by immersion, selective removal or vaporization (layers of 25-50 microns). Preferably, the distance between the emitting face or emitting zone (spaced apart or not from the wafer) and the injection wafer may be less than 2 mm. The diodes may be (pre) encapsulated, that is to say comprising a semiconductor chip and an envelope, for example epoxy resin or PMMA, encapsulating the chip and whose functions are insulating: diffusing or focusing element, wavelength conversion. The envelope is common or individual.
    [0030] The diodes may preferably be single semiconductor chips, for example with a size of the order of one hundred pm or one millimeter. The diodes may optionally comprise a protective envelope (temporary or not) to protect the chip during handling or to improve the compatibility between the materials of the chip and other materials.
    [0031] The diode may be chosen in particular from at least one of the following light-emitting diodes: a side-emitting diode, ie parallel to the (faces of) electrical contacts, with a lateral emitter face with respect to the support, a diode whose main direction of emission is perpendicular or oblique with respect to the emitting face of the chip. The diode support profile can be a conventional PCB or be metallic The diode support profile can have a rectangular section. The total number of diodes, the power of the diodes are chosen by the size and location of the areas to be illuminated, by the desired light intensity and the required light homogeneity.
    [0032] The length of the diode support profile varies depending on the number of diodes and the extent of the surface to be illuminated. Preferably, the transmission factor of the first sheet around the peak of the radiation of the chips (perpendicular to the main faces) is greater than or equal to 50%, even more preferably greater than or equal to 70%, and even greater than or equal to 80% . For the coupling edge or edges of the first sheet, it is possible to provide rounded edges. Particularly in the case where the emitted radiation space is air, it is possible to take advantage of the refraction at the air interface / first sheet of appropriate geometry (rounded edge, or even bevelled ... ) thus allowing to focus the rays in the first sheet. The glass may have optionally previously undergone a heat treatment of the type hardening, annealing, quenching, bending. The edge of the first sheet (trimming with recesses before soaking) can be cut from an insulating glazing unit to house the diodes. The first and / or second sheets can be of any shape (rectangular, square, round, oval, ...), and be flat or curved. The first sheet may be preferably soda-lime glass, for example PLAN ILUX glass from the company SAINT GOBAIN GLASS.
    [0033] The light extraction means guided via the first and / or the second main face are surface diffusion means of the first and / or second main face or volume diffusion means in the first sheet. light extraction is used diffusion means, formed either by a surface treatment of sandblasting type glass sheet, acid attack, deposition of enamel or diffusing paste, or by a treatment in the mass of the glass of type laser engraving. The diffusing particles may be chosen from semi-transparent particles and preferably mineral particles such as oxides, nitrides, carbides. The particles will preferably be chosen from oxides of silica, alumina, zirconia, titanium, cerium, or a mixture of at least two of these oxides. For example, a diffusing mineral layer of about 10 μm is chosen. The distance of the emitting face and the first sheet may be less than 2 mm. In particular, it is possible to use diodes with reduced bulk, for example chips without a lens and / or without pre-encapsulation, in particular with a width of the order of 1 mm, a length of about 2.8 mm, a height of the order of 1.5 mm. The luminous zone or zones, in particular are peripheral, in band (s) framing the glazing.
    [0034] The light can be: - continuous and / or intermittently, - monochromatic and / or plurichromatic. As decorative patterns, one can form for example one or more light strips, a peripheral light frame.
    [0035] The invention also relates to a method of manufacturing a luminous glazed assembly as described above in which the attachment piece is fixed on the first seal still in the tacky state. The manufacturing method may include the following steps in this order. a cavity defined by the injection edge is formed, the fixing piece and the bottom piece forming a lateral recess of the fastener, cavity along the injection edge and opening laterally, the source is housed; of light and the source support in the cavity, - is closed by a cover the cavity in the longitudinal direction of the injection edge the remaining cavity opening laterally - the mounting profile is mounted to the insulating glass by gluing, with the glue or double-sided, including the frame amount facing the injection edge. Better, for disassembly, (it is arranged that) the mounting adhesive of the optional profile is absent at least between the frame amount and the lateral end of the cavity, and the frame profile having a recess covered by a waterproof cover and with sealing means, the cover and / or the sealing means being removable and forming access hatch to the source and the assembly preferably allowing the passage of power supply son of the source, the cover and / or the sealing means are removed, the source is removed. by the lateral end of the cavity The recess is preferably in said amount adjacent to the amount facing the injection edge.
    [0036] The fastener and / or the bottom piece or the second slice can protect the light source from misalignment and / or crushing against the injection edge. Other details and advantageous characteristics of the invention appear on reading the examples of glazing according to the invention illustrated by the following figures: FIG. 1a shows a refrigerated luminous enclosure - FIGS. 1,1 ', 1a, 2 , 2 ', 2 ", 3, 3a, 3b, 3c, 3d, 3', 5a to 5g, 6, 7, 8 show schematic and partial cross-sectional views of the refrigerated furniture lighted glass doors in various embodiments. 4a is a schematic front view of a light refrigerated cabinet door with access hatch of the light source - FIGS. 4b and 4c show the access door.
    [0037] It is specified that for the sake of clarity the various elements of the objects represented are not necessarily reproduced on the scale. Figure la shows a schematic view of a refrigerated enclosure 1000 in a first embodiment of the invention.
    [0038] This enclosure is here a cabinet with shelves 101 (in dashed lines) and two doors each comprising a light insulating glazing unit having an external main face 11 on the user side (visible here) and an inner main face (shelf side) and a slice with four edges . The longitudinal edges of the wafer are vertical. A framing profile is a frame fixed at the periphery of the insulating glass (double glazing or triple glazing) rectangular. The frame has four studs abutting the corners of the insulating glass. The two longitudinal uprights 7a and 7b are identical and vertical. Two lateral uprights 7c and 7d are horizontal. Two light sources (dashed or masked) are inserted respectively between the first longitudinal upright 7a and a first longitudinal edge 13a of the slice and between the second longitudinal upright 7b and a second longitudinal slice edge. Each door is open to the outside thanks to a 7p pivot on the upper and lower uprights. FIG. 1 represents a partial diagrammatic sectional view of a light refrigerated cabinet door 100 in a first embodiment of the invention. This luminous glazed door 100 comprises an insulating glazing unit with an external main face 11 on the user side and an inner main face (12 'on the tablet side) comprising: a first glazing unit comprising the external face and a first section consisting of four edges, a first edge of which longitudinal 13a, first simple glazing comprising a first glass sheet 1 having a first main face 11 and a second main face 12, the first face therefore being the outer face, for example a silicosodocalcique and extraclair glass sheet, of equal thickness at least 3.8mm (4mm in or 6mm standard), a second glazing having the inner face 12 'and a second slice formed of four edges including a second longitudinal edge 13'a, second glazing here simple comprising a second glass sheet 1 ', with a third face 11' and a fourth main face 12 'being here the inner face, the second and third faces being spaced apart by a first gas strip, - at the periphery of the second and third faces a first polymeric seal 3 in a frame and a spacing spacer spacer 3 '.
    [0039] Usually, the spacer 3 'is fixed inside the glazing by its side faces to the faces 12 11' of the glass sheets by butyl rubber 81 which also serves to seal the interior of the insulating glazing with steam of water. The spacer 3 'is set back inside the glazing and near the longitudinal edges of the slices of said glass sheets, so as to provide a peripheral groove into which are injected a first polymeric seal 3 of the mastic type, such as in polysulfide or polyurethane. The sealant confirms the mechanical assembly of the two glass sheets 1,1 'and ensures a seal with liquid water or solvents. A light source 2 is external to the insulating glass. Electroluminescent diodes 2 each having a semiconductor chip with an emitting face 21 are preferred. The diodes are optically coupled with the first longitudinal edge 13a, called the injection edge, for propagation of light by total internal reflection in the emitter. thickness of the first glazing, then playing the role of guide light. The diodes are on a printed circuit board or PCB support 20 and extend facing the first (injection) edge 13a. The PCB support 20 is monolithic, thin, with a thickness equal to 1.8 mm wide by 5mm. It is a flat part (strip) of rectangular section, "FR4" or metal.
    [0040] The PCB support 20 does not protrude from the first wafer towards the outer face and is here on a metal for heat dissipation. The light-emitting diodes each having an emitter chip capable of emitting one or more visible-light radiations guided in the first sheet 1. The diodes are small in size, typically a few mm or less, conventionally no more than 2 mm thick, in particular of the order of 2x2x1 mm. The diodes are with or without optics (lens), not pre-encapsulated to minimize congestion or encapsulated for example a simple varnish. The emitting faces are preferably spaced apart from the injection edge and without adhesive contact but may be pre-thickened and bonded by a double-sided adhesive or optical tape preferably of thickness of at most 0.5 mm. It is possible to choose diodes emitting in white or colored light. The distance between the emitting face and the injection wafer is minimized, for example by 5 mm, better still from 0.2 to 2 mm. The main direction of emission is perpendicular to the face of the semiconductor chip, for example with a quantum multiwell active layer of AlInGaP technology or other semiconductors. The cone of light is a lambertian-type cone, of +/- 60 °. In the configuration illustrated, the emitting face 20 of the chip is perpendicular to the PCB 20. The extraction of the light 12 'is for example via the outer face 11.
    [0041] The extraction 12 'is carried out by any diffusion means on the surface of the second face 12: sandblasting, acid attack, diffusing layer such as white enamel ... or alternatively by laser etching in the first sheet 1. The light pattern may be for commercial purposes, signage .... The second glazing 1 'has a first thermal function layer 15, on the third face 11'. The PCB support 10 and the source 2 are in a cavity delimited by the injection edge, a so-called attachment piece 4, a bottom piece 5, and closed by a cover 6 longitudinally. This elongate cavity is laterally open. The fastener 4 is a metal profile, here a sheet -extruded or folded-aluminum thickness Ep4 1.5mm forming a hollow part of rectangular section of thickness E4 7mm. This profile 4 is mounted on the sealant 3 still in the tacky state (the glazing is generally horizontal) so that the outer edge of the sealant 31 is in direct adhesive contact with the fastener, which can be inserted typically from 1 to 3mm in the mastic 3. The projecting thickness E'4 is for example 5mm. The fastener 4 does not touch both first and second glazing not to form a thermal bridge. It may in particular be spaced 2mm from the second face 12 so that the source support does not protrude towards the outer face. The fastener 4 protects the light source 2 from misalignment and / or crushing against the injection edge, protruding opposite the injection edge by its flat rear portion 42. The bottom part 5 is as for it opposite and spaced from the injection edge, it is here a lateral recess of the fastener so is a flat of thickness Ep5 1.5mm in the extension of the flat rear wall 42. The folded or extruded aluminum sheet to form a fixing piece and a bottom piece. The bottom piece 5 could even be bent towards the injection edge without touching it or by touching it (if the fastener 4 does not touch the second glazing preferably) if the diodes on PCB support are mounted by sliding via lateral end of the open cavity.
    [0042] The glazing further includes a cover 4 closing the cavity, closing in the longitudinal direction of the injection edge 13a. The cover is a metal sheet 6 adhesive-coated 50 to 100 μm thick with a portion 62 bonded to the outer face 11 by creating a small excess thickness of at most 1 mm and a portion 61 bonded to the fastener via its rear face.
    [0043] For example, an aluminum foil adhered by double-sided adhesive or a metal tape with an adhesive on its side injection edge side To insert diodes after rollover or change them it is not necessary to disassemble the cover 6 because one can insert or leave the diodes on their support PCB or an optical fiber on its support as shown in figure ibis) laterally preferably by the top of the door. we can also insert the diodes before rollover. Also the PCB support 20 and the diodes 2 above are inserted into the cavity against the bottom part, non-adhesive contact with the metal bottom piece or the metal fastener and even without fixing that would prevent its desired withdrawal laterally. A magnetic attachment contact is possible. A possible slight gap between diodes and the injection edge is possible if it does not disturb the optical alignment. The bottom part 5 heat sink form. It is preferable to avoid force-mounting and even close-fitting. In addition, the cover piece is provided with a recess 50 blind or through (sealed by foam or gasket ...) for the passage of the connector. The fastener-base part-hood assembly is associated with the insulating glazing without creating a thermal bridge. The hood and the attachment piece reflect the lateral light to direct it towards the injection edge.
    [0044] The glazed door 100 further comprises a frame profile fixed to the insulating glazing preferably by a said mounting adhesive 8 and masking first seal 3 and spacer 3 '. It comprises a longitudinal frame amount 7a (vertical on the mounted door) along the injection edge 13a fixed to the insulating glass by the mounting glue 8, and here in adhesive contact with the glue with the fastener, the piece bottom, the hood, the mounting glue 8 being absent from the space between the light source and the injection edge and better the space between the end of the cavity open laterally (upper on the mounted door) to save access (as detailed later). The amount of framing 7a is in two parts to avoid the thermal bridge (if metallic). A first metal portion 70 is bent, for example section section L, to be opposite the injection edge () and protrude on the outer face: - with a portion 71 bonded to the outer face and a portion (flat) the cover used to close the cavity, - with a portion 72 facing the edge of the insulating glazing (and offset from the edge 13'a of the second glazing), glued to another portion of the cover 61, to the bottom piece (rear face 51), to the fastener (rear flat portion 42) The second portion 70 'is heat insulating, preferably polymeric secured by an adhesive 80 with the first portion, bent, to be opposite the second portion 13 adjacent the injection edge and protruding on the inner face 12 '. The mounting of the frame profile is preferably horizontal, with the cover closing the upper part of the cavity. FIG. 1 shows alternatively and in detail view of the door 100 'a bottom part 5. and fastening 4 in two integral parts, with an L-shaped bottom piece with a short portion of the L bonded by a double-sided adhesive 80 'to a lateral portion 40 of the fastener 4.
    [0045] Figure 2 shows a partial schematic cross-sectional view of a refrigerated furniture light door 200 in a second embodiment of the invention. The door 200 differs from the door 100 by the choice of side emitting diodes with emitting face parallel to the PCB support 20, and therefore the position of the PCB support 20 which is here against the lateral part 40 of the metal fastener (bottom of the cavity). The fastener can touch the face 12 of the first glazing (second face) for example to center (raise) the diodes in the middle of the guide glass 1. Otherwise the thickness of the PCB is adapted for example If the piece 4 becomes a plastic we can insert a metal part. . FIG. 2 'is a partial cross-sectional schematic view of a refrigerated cabinet light glazed door 200' in a variant of the second embodiment of the invention.
    [0046] The door 200 'differs from the door 100 by the choice of side emitting diodes with emitting face 21 parallel to the PCB support 20, and therefore the position of the PCB support 20 which is fixed (removable or not laterally) on the cover 6' of closure of the cavity which is here an extension of the bottom piece and it monolithic with the attachment piece 4 (metal like an aluminum sheet) of Ep4 thickness kept at of at most 1.5mm. The thickness of the cover Ep6 (or of the bottom piece 5) is less than 1mm and even 0.8mm to not create extra thickness on the outer face 11. The monolithic piece is for example an extrudate. Alternatively the PCB support is against the fastener 3 or we keep the side emission diodes with PCB support against the fastener 3.Cela avoids having to fix the PCB support. If we reduce the thickness of the monolithic part forming bottom and fixing part and hood under 1mm it is preferred that the second glazing is protruding to protect the diodes. FIG. 2 "represents a partial schematic view of a cross-section of a refrigerated furniture light door 200 "in another variant of the second embodiment of the invention. The door 200 'differs from the door 100 by the choice of side emitting diodes with emitting face 21 parallel to the PCB support 20, and therefore the position of the PCB support 20 which is fixed (removable or not laterally) on the cover 6' of closing the cavity which is here an extension of the bottom piece. The thickness of the cover Ep6 (or of the bottom piece 5) is less than 1mm and even 0.8mm to avoid creating extra thickness on the outer face 11. The monolithic piece hood bottom piece is for example a extrudate. The bottom piece is separate from the fastener 5 and fixed by gluing 80 by a return. Figure 3 shows a partial schematic cross-sectional view of a refrigerated furniture light-door 300 in a third embodiment of the invention. The door 300 differs from the door 100 by the dimensions of the second glazing 1 'whose second wafer 13' protruding from the injection edge 13a protrudes from the source support 20, and even from the attachment piece 4 and the workpiece bottom 5, and the cover on the rear face of the protruding bottom part opposite the injection edge protecting the light source including misalignment and / or crushing against the injection edge. The second slice is closer to the polymeric portion of the frame profile 7a It may be in the back of the 1mm attachment piece and at most 3mm for example to avoid creating extra thickness of glazing. Figure 3 'shows a partial schematic cross sectional view of a refrigerated furniture light glass door 300' in a variant of the third embodiment of the invention. The door 300 'differs from the door 300 by the section of the amount of frame 7 which does not include a return on the inner face 12', in particular is of section L. And the inner face 12 comprises masking means 17 of the first seal 3 and the spacer 3 'namely a sufficiently opaque enamel for example black or white optical density equal to 3.
    [0047] A mixed solution consists in making the profile 70 'pass only over a short distance that does not mask all the peripheral means 3 and 3', the layer deposition masking means completing the masking.
    [0048] Figure 3a shows a partial schematic cross-sectional view of a refrigerated furniture light glazed door 300a in a variant of the third embodiment of the invention. The door 300a differs from the door 300 by the cover which extends to form the bottom part 5, 62 and with a portion 63 extending even to attach to the rear face 42 of the fastener. The PCB support is therefore pre-mounted on the rear face of the fixing piece In a removable variant, the PCB support is against the side face 42 and the cover is in contact with its edge support preferably non-adhesive contact. A plastic square (with internal reflector) fixed rear face 40 of the fixing part is then chosen.

The door 300b differs from the previous door 300d because the source support is in direct adhesive contact in the sealant as the metal fastener here a section of rectangular section. The cover 6 is an adhesive-coated metal sheet extending from the outer face 11 to the side face 43 opposite to the face 40. FIG. 4a shows a partial schematic front view of a light refrigerated display cabinet door 100 "in a variant. of the first embodiment of the invention with an access door of the diodes on their PCB support The framing profile comprises a recess 73 covered by a perforated cover piece 9 with sealing means as a seal 91 4b (sectional view) and 4c (seen from above) Here, the seal 91 is drilled in the center (orifice 9b) allowing the passage of electrical supply wires 90 from the source and radially (orifice 9a) for The seal is also removable and forming an access hatch to the source The orifice 9b is the cover 9 is for example glued to the amount of upper frame (horizontal) and may also include a pivot 7p.
